Montmorillonite Powder

Montmorillonite Powder is the kind of montmorillonite clay that has a significant amount of calcium as a component of the mineral composition of the clay. Bentonite montmorillonite powder is a more accurate word for montmorillonite clay that includes a large proportion of bentonite in its composition. Some parallels are to be drawn between montmorillonite clay and bentonite clay.

Wax Emulsion for Drilling Fluid

Wax emulsion can not only be used in drilling mud, but also widely used in the fields of coatings and inks, paper and packaging, and plastics.

In the textile and leather industries, it is used as a wear-resistant agent, lubricant, and matting agent, while the use of wax emulsion in leather can give it a better feel and can prevent stains and protect it.

It can be said that the application of wax emulsion is extremely wide.

In addition to the applications we mentioned above, it can also be applied to the ceramic industry, concrete maintenance and sealing industry, as well as adhesives, sealants, and cosmetics.

Wax Emulsion for Drilling Mud

Wax Emulsion

Wax emulsion is used in drilling mud. The first role it plays is to protect the stability of the well wall, and to play a role in lubrication and reducing resistance. At the same time, it can effectively reduce its filtration loss and protect the reservoir.

The reduction of filtration loss is mainly because drilling fluid is more likely to lose drilling fluid, which affects the stability of the well body.

Therefore, we use wax emulsion to seal the gaps in the formation and form a more resilient membrane, so that the pressure membrane of the well wall is not easy to be broken.

Camp Shinning – Pioneer and leader in environmental remediation

Camp Shinning is the leader and pioneer in cutting-edge environmental remediation solutions. Around the globe, our innovative teams of clay mineralogists, chemists, and polymer scientists transform ordinary minerals into extraordinary technology to solve day-to-day problems worldwide.

 

 

Organoclay is an organically modified phyllosilicate, derived from a naturally occurring clay mineral. By exchanging the original interlayer cations for organocations (typically quaternary alkylammonium ions) an organophilic surface is generated, consisting of covalently linked organic moieties. The lamellar structure remains analogous to the parent phyllosilicate.

 

Separation of the layers due to ion exchange, from the initial interlayer spacing of as little as 3 Å in the case of Na+ cations to the distances in the range of 10–40 Å as well as the change of chemical character of the clay surface, allows the in-situ polymerization or mixing with certain polymers to obtain what is known as nanocomposite. When ordered aluminosilicate sheets are lying parallel to each other, separated with polymer chains of certain type, the system is classified as intercalated nanocomposite. If separation of the layers is so significant, that they are no longer lying opposite to one another, but randomly ordered, then one get the exfoliated nanocomposite.

 

Applications

Owing to its large surface area together with hydrophobic chains emerging from the clay surface, organoclay can be used to remove oil from water. It is also applied as a component in paint formulations or as a viscosifier for oil-based drilling fluids.

 

It can be used in polymer chemistry as a nucleating agent.

What is Organoclay?

How Organoclay is Used and the Benefits

 

Organoclay is a naturally occurring material that is commonly used in water treatment. Organoclays are well known for their high removal rate of oils and other hydrophobic compounds in water. The media is a naturally occurring mineral (commonly zeolite, bentonite clay, or a smectite mineral) which is chemically alternated to create a unique surface on the mineral. Camp Shinning’s organoclay is a zeolite based organoclay which has does not swell upon exposure to water.

 

How does Organoclay Work?

Camp Shinning alters zeolite with a surfactant bilayer that enhances the media’s ability to remove pollutants. The surfactant bilayer is created when a quaternary amine or surfactants is added to the mineral to modify the surface commonly referred to as surface-modified-zeolites (SMZ). By modifying the surface, we create a strong affinity with either cations (positively charged ions, i.e. dissolved metals) or anions (negatively charged ions, i.e. phosphate, nitrate). The bilayer that contains hydrophobic chains will capture non-polar organics such as benzene.

How is Organoclay Used?

Organoclays are used in various industries including remediation, water treatment, soil treatment, in polymer chemistry, in paints as a thickening agent, grease, inks, oil drilling fluids, rheological products, cosmetics, and many more commercial and industrial applications.

 

What are the Benefits of Using Organoclay?

Versatile installation — Load the media in standalone units, post-treatment, or pre-treatment units. To learn more about these systems on our Water Filtration Systems Page.

 

Cost Savings — Organoclay is an economical alternative to other treatment technologies such as resins or Granular Activated Carbon (GAC).

 

Increase Efficiency — Organoclays will decrease the loading on other treatment systems and increase the life of capital equipment.

 

Storage — Organoclays have a long shelf life and require dry ambient environments.

 

Handling — Organoclays are safe and easy to use.

 

How is Organoclay Used in Water Treatment?

CP-200 Liquid Phase, Pure Organoclay

Organoclays are used in industrial and commercial water treatment such as:

Condensate Treatment Systems: Condensate treatment is part of every power plant, refinery, chemical manufacturer, and any facility that uses stream. Typically, the condensate is recycled back into the boiler feed water where it is routed through boiler tubes for continued boiler use.

 

Recycling condensate is a common practice which decreases the amount of water disposal but can be costly if not designed correctly. By not treating the condensate that goes back into your boiler feed water you are introducing high concentrations of pollutants that came off leaking pumps, valves, and piping to your boiler tubes. When these pollutants (hydrocarbons and minerals) are introduced to the boiler tubes they will deposit on the surface which will reduce the heat transfer and overall reducing the boiler efficiency.

 

Camp Shinning’s works with condensate treatment manufacturers and users on providing a specialty blend of filter material for treating the pollutants that are commonly found in condensate. The condensate treatment blend of filter media uses organoclay and activated carbon to trap the contaminates in its’ pore structure.

 

 

Process Water Reuse Systems: Leaking pipes, valves, vessels, or inefficient processes can leave process water tainted with low concentrations of pollutants. These pollutants over time can lead to hazardous water that needs to be hauled off site for treatment. A common use of organoclay is to treat process water onsite in a vessel to reuse the water instead of discharge it or accumulate it and haul it off-site as hazardous waste. Tainted water can lead to downtime of capital equipment and hefty bills for hazardous waste disposal. Examples of process water treatment systems might include the wash water that is used in a metal plating facility, or batch water that has low concentrations of acrylic paint thinner. Simply installing a vessel of organoclay in a process water loop can significantly reduce planned and unplanned downtime.

 

Organoclays are used in remediation projects such as:

Groundwater Treatment: Pump-and-Treat Systems are typically implemented when groundwater is contaminated. For pump-and-treat systems, the water is typically pumped out of the ground into a large vessel. The large vessel or series of vessels is filled with a filter media (i.e. granular activated carbon, organoclay, resin) that removes any pollutants of concern such as heavy metals or oil. The water is then put back into the ground. Pump-and-treat are cost-effective designs for treating water if you select the most appropriate filter media to target your pollutants.

 

Sediment Capping: Capping, also known as permeable reactive barrier  , is an in-situ remediation technology that typically follows dredging operations. Organoclay is used in sediment capping due to its’ ability to isolate contaminated sediment from a surrounding aquafer or aquatic system. It is a cost-effective material for capping as it has strong affinity for removing high molecular weight polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and heavy metals.

 

Stormwater Treatment: Organoclay is used to improve water quality in stormwater runoff. Typically, pollutants found in stormwater are monitored by state regulators to ensure we have clean lakes, rivers, oceans and wetlands

Rheological Additive for Solvent Base System

CP-200 is an organic derivative of bentonite clay act as Rheological additive in low to high polarity systems. Such as Ketones, Glycol, Alcohol, Esters and Ethers, includes Polar System with some Aromatic Solvents.

Properties & Markets

Paints & Coatings : A small addition of ORGANOCLAY can greatly enhance the rheological properties of the paint system. These properties prevent pigment settling and sagging on vertical surface to ensure the proper thickness of the coating is applied. They also ensure good leveling for the removal of brush marks.

Storage stability is guaranteed even with high temperatures. ORGANOCLAY confer water resistance and structure reinforcement with no adverse effect on adhesion and solvent relese. Gloss is minimally affected due to the low levels of addition. ALL ORGANOCLAY are used widely in a vast range of solvent based paint systems

Architectural Paints : Undercoats, Primers, Semi-Gloss, Gloss and Wood Stains

Industrial Coatings : Air Drying, Stoving Enamels, Epoxies, Esters, Urethanes, Vinyls, Acrylics, Anti-Corrosive, Automotive, Bitumionous, Coil, Road Marking, Underbody Car Coatings, Nitro Cellulose and Chlorinated Rubber.

Printing Inks : With the correct ORGANOCLAY, is possible to adjust the consistency of printing inks to the desired values, avoiding pigment sedimentation, providing good color distribution obtaining desired film thickness, reduction in misting, control of track, water pick up and dot gain control. ORGANOCLAY are used in much letterpress, lithographic and offset ink.

Lubricating Greases : Thickening lubricating oils with ORGANOCLAY can produce specialty high temperature resistant lubricating greases. ORGANOCLAY also gives good working stability and water resistance to the greases. Such greases are typically used for lubrication in foundries, mills and on high speed conveyors. Other greases can be manufactured for other industries such as agriculture, aviation, automotive and mining.

Cosmetics : The performance of cosmetics is enhanced by the use of ORGANOCLAY and they allow good colour retention and coverage for nail lacquers, lipsticks and eye shadows. They have been tested to be non-irritant for both skin and eye contact.

Food Contact Applications : ORGANOCLAY are used as thixotropic agents in coatings that come into contact with food. They are also used as fillers in plastic food containers. They are acceptable under current EEC legislation on food contact additives.

Drilling Fluids : ORGANOCLAY are used extensively in drilling fluids throughout the world. They are used to suspend the heavy sealing agents, normally barytes and carry the cuttings back to the surface. They also play an important part in lubricating the drill. ORGANOCLAY can also be used as fracfluids, where the gelling ability of them is used to seal rock fractures in the bore hole.

Nanofiller for Plastic : Highly purified organoclays because of their particle size and chemical structure have the unique ability to be able to function in a wide range of monomers and polymers. The resulting properties of polymers, compounded with these unique organoclays include :

  1. Increased Modular Strength without Sacrificing Impact Resistance
  2. Improved Gas Barrier Properties
  3. Increased Solvent and Heat Resistance
  4. Improved Fire Retarding Properties

The combination of these improved properties, convenient processing and relative low costs, makes nano composites a tremendous commercial opportunity as they are superior alternatives to the current fillers used in polymer systems.

 

Hectorite and Bentonite based organoclay grades

Optimum activation of organoclays by ideal organoclay for highest effectivity

 

 Correct activation for highest efficiency

❖ Optimum shear applied for proper delamination

❖ Correct use of polar activator for conventional grades

❖ Right order of addition for best processing result

organoclays can be optimized by improved process parameters including a review of the process temperature.

However, temperature control during organoclay dispersion in solvent based systems is not as important as with e.g.

organic thixotropes.

Various methods used in manufacturing formulations and procedures sometimes suffer in efficiency when order of addition and mixing conditions are less than optimum.Further, the effects of solvent resin temperature on process development and final results will be discussed.

organoclay materials are based on either

bentonite or Hectorite, both minerals from the smectite group. They consist of microfine platelet stacks that, due to their mineralogical structure, expand in water in their natural form. In order to make them compatible with non-aqueous media such as organic solvents, however, it is necessary to modify the surface of their silicate plates with quaternary ammonium compounds.

The choice of this modification and processing conditions also plays an important role in the practical applicability and performance capabilities of the finished end systems. The resulting organoclay will be dried and milled to achieve a powdered material.

To be most rheologically effective, the size of the individual platelets and the total combined edge length following their successful activation is decisive.

the Hectorite platelets are significantly smaller than the bentonite ones, the resulting edge length per gram of silicate in the Hectorite is much larger.

This makes Hectorite additives able to build up a much denser and more rheologically effective network. In order to be activated, organoclays must first be exposed to high shear forces over a defined swelling period.

What is organophilic clay?

Organophilic clay is a type of clay that has been chemically modified to be compatible with organic solvents and non-aqueous systems. It’s a viscosifier and gelling agent used in various applications, including drilling fluids, paints, and cosmetics.

 [Drilling Fluids]

Clay minerals whose surfaces have been coated with a chemical to make them oil-dispersible. Bentonite and hectorite (plate-like clays) and attapulgite and sepiolite (rod-shaped clays) are treated with oil-wetting agents during manufacturing and are used as oil-mud additives. Quaternary fatty-acid amine is applied to the clay. Amine may be applied to dry clay during grinding or it can be applied to clay dispersed in water. The latter process is much more expensive, requiring filtering, drying and other manufacturing steps. Organophilic bentonite and hectorite, “bentones,” are used in oil muds to build rheology for cuttings lifting and solids suspension. They also contribute to low-permeability filter cake. Organophilic attapulgite and sepiolite are used in oil muds strictly to build gel structure, which may not be long lasting due to shear degradation as the mud is pumped through the bit.

CP-2 organophilic clay is a viscosifier and gelling agent used in VERSA oil-based and NOVA synthetic-based systems. This amine-treated bentonite is used to increase carrying capacity and suspension properties, providing support for weighting agents and improved cuttings removal. CP-2 viscosifier also aids in filtercake formation and filtration control.

Applications

CP-2 viscosifier is proven effective in drilling, coring, workover and completion fluids. The product is also effective in specialty applications such as casing packs, packer fluids and spotting fluids. Good agitation and sufficient shear are required to develop viscosity when using CP-2 viscosifier to build fresh mud.

 

Typical concentrations range from 2 to 10 lbm/bbl [5.7 to 28.5 kg/m3] for most drilling fluid applications, depending on the base fluid and system requirements. Mineral oils generally require higher concentrations than diesel oils. CP-2 viscosifier will not fully yield by the shear and temperature exposure in a mixing plant or mud pit. Care should be taken not to overtreat with CP-2 viscosifier until the fluid has actually circulated through the well. For system maintenance, CP-2 viscosifier should be added as needed to maintain the flow properties and gel strengths in the desired ranges. Specialty applications such as packer fluids and casing packs typically use concentrations in the 10 to 15 lbm/ bbl [28.5 to 43 kg/m3] range.

 

Advantages

Provides gel structure and viscosity for the suspension of weight materials

Increases viscosity for improved hole-cleaning capacity

Improves filter-cake quality and filtration characteristics

Effective gelling agent in casing packs and packer fluids

Toxicity and handling

Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions described in the safety data sheet.

 

Packaging and storage

CP-2 viscosifier is packaged in 50-lb [22.7-kg] multiwall paper sacks. Store in a dry, well-ventilated area. Keep container closed. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping, and stacking.

 

So far I’ve had no luck finding organophilic clays like CP series in China apart from one drilling company that wanted upwards of $200 for a 25Kg bag of oil drilling product. I did a trawl of online patents to see how hard the stuff is to make.

 

Both these chemicals are used in fabric softeners and are available as industrial chemicals. Buying the bentonite and the surfactants above might be a bit more common compared to bentone in countries that don’t drill for oil much.

 

Is it going to be easy to buy these industrial surfactants than Bentone?, probably is if you can find an industrial chemical supplier who’ll sell you less than a 200 litre drum.

 

Organophilic Clay

Organophilic clay is a wet process improved viscosifier and gelling additive, derived from a naturally occurring clay mineral.

Feature

Organophilic clay has good performance efficiency in diesel, mineral oil and synthetic Oil; It can effectively suspends weighting materials and other solids, maintains suspension over a wide temperature range.

 

Application

Organophilic clay is a self-activating gallant offering rapid yield development, high gel strengths, and increased efficiency.

Montmorillonite Powder

Introduction

A member of the smectite family of minerals, montmorillonite clay is distinguished by its peculiar structure, which consists of two layers of silica sheets sandwiching an aluminum sheet in the middle. To examine the particles, which are planar and have an average diameter of around one meter, one needs an electron microscope with a high enough magnification..

It’s a soft clay mineral that precipitates out of mineral-rich aqueous solutions as small crystals. The French village of Montmorillon is where the name originated. The mineral montmorillonite is often found in soil that has expanded. Montmorillonite is a kind of clay that can absorb varying amounts of water, greatly swelling the material when wet.

The process of crushing the clay into a fine consistency, resulting in a powder that may be used in a wide variety of settings. The positive properties of clay, namely its high cation exchange capacity and propensity to absorb water, are preserved in montmorillonite powder.

 

Surface and Interface Chemistry of Clay Minerals

Because of its unique chemical composition, bentonite montmorillonite clay belongs to a class of clay minerals like bentonite, than other types of clay. Montmorillonite clay layers that are built of silicon, the surface is made up of oxygen atoms. It can have aluminum or magnesium.

 

Bentonite

Bentonite clay vs montmorillonite clay are both types of clay and thickening agent. In the same way as bentonite clay falls within the smectite group of minerals, so does montmorillonite powder. Montmorillonite powder may be obtained from montmorillonite clay. It is mostly made up of mineral crystals that are either sodium or calcium montmorillonite. In short, bentonite is a naturally occurring mineral that is mined and processed by Zhejiang Camp-Shinning to produce montmorillonite clay and/or montmorillonite powder.

 

Montmorillonite Structure

Indeed, montmorillonite clay and montmorillonite powder possess incredible characteristics that makes it so important and helpful in a lot of industries. Here are some of its characteristics and properties.

 

Physical Properties

Montmorillonite typically has a density ranging from 2 to 3 grams per cubic centimeter when it is measured. Its crystal system is classified as monoclinic. This material is relatively soft, with a rating of only 1 to 2 on the Mohs scale, and is commonly discovered in a fine-grained form. Montmorillonite breaks in an irregular and uneven way, but it has a perfect cleavage.

The mineral doesn’t have a very bright shine and looks matte. It’s slightly transparent, allowing a small amount of light to pass through. Montmorillonite powders are available in various colors like white, buff, yellow, and green. The color of it may appear pale pink to red due to the presence of high-valence manganese. Montmorillonite’s physical properties play a crucial role in its identification and classification within the geological and material science domains.

 

Chemical Properties

It has a unique physical structure due to their layered sheets, which also define its chemical properties. It is made up of two types of structural sheets. It is tetrahedral sheet and the octahedral sheet. Tetrahedral sheet is made up of silicon-oxygen tetrahedra that are connected to each other.

When multiple tetrahedrons are placed together, they share three corners with each other. This creates a network that has a hexagonal shape. The fourth corner of every tetrahedron is linked to the adjacent octahedral sheet. The octahedral sheet consists of aluminum or magnesium atoms that are typically enclosed by six oxygen atoms from the tetrahedral sheet, as well as some hydroxyl groups.

It has a specific chemical formula of (Na,Ca)0.3(Al,Mg)2Si4O10(OH)2·nH2O. It has sodium, calcium, aluminum, magnesium, silicon, oxygen, and hydrogen. According to the International Mineralogical Association, the symbol for Montmorillonite is Mnt.

Typical Applications

Montmorillonite powder has many uses, but one of its most notable applications is in drilling fluids for oil exploration. This application benefits greatly from its unique properties, which make it highly effective. When you add Montmorillonite powder to drilling fluids, it can help you control the viscosity, improve lubrication, and enhance the overall fluid stability. When it absorbs water, it expands and creates a barrier that protects boreholes from collapsing. This barrier also helps in removing drilling cuttings.

Synonyms

In Spanish, it is referred to as arcilla montmorillonita, emphasizing its clay-like nature. In French, it is known as argile montmorillonite, highlighting its classification as a type of clay mineral.

 

Classification

As mentioned above, montmorillonite powder is classified as smectite clay mineral group together with bentonite, nontronite, saponite, hectorite and beidellite.

 

Functional Properties

Cation Exchange Property

If you break up montmorillonite clay into smaller particles, you’ll see that it has a bigger surface area in relation to its weight. When particles are made smaller to about 0.002-0.001 mm in diameter, their surface area increases significantly. The surface has the ability to attract and hold a larger amount of positively charged ions. The electrical conductivity of Montmorillonite clay is greatly affected by the cations that it absorbs. Modifying the ions in the sheet structure can bring about beneficial enhancements..

 

Electrical Conductivity

The particles of clay have pores. The flow of electricity through a pore is influenced by the fluid present inside it. Porous materials such as montmorillonite clay or powder have their electrical conductivity determined by both the electrical conductivity of the matrix material and the fluid present within the pores.

If there are a greater number of clay particles with a structure in a sample of montmorillonite, the overall electrical conductivity of non-saline soils will go up. The presence of exchangeable cations may be the cause. Additionally, it can cause the transfer of protons due to the dissociation of water content between layers. Montmorillonite clays exhibited the lowest electrical conductivity when there was a reduced amount of water present between their layers.

 

Heat Resistance

It has excellent insulating properties against heat. It is possible to increase the heat resistance of other materials by including it into their composition.  Clay minerals, such as montmorillonite and bentonite, have been used by people for their thermal barrier qualities in a variety of applications that need heat resistance as well as flame retardancy. In order to make polymer composites more resistant to heat and fire, nanoclay is now seeing widespread use and research as a potential additive.

 

Water Sorption | Montmorillonite Powder

In response to changes in the relative humidity of their immediate surroundings, montmorillonite clay particles may either take in more water or give up some of the water that they already contain. When water is absorbed, it fills the spaces that are left behind between the layers of silicate that have been piled. Because of how it interacts with water, beneficial properties are brought into play as a consequence of this interaction. Because water molecules are present, it swells up as a consequence of their existence. This swelling is a result of the complex montmorillonite-water interactions that take place both between the particles and inside each particle itself. These interactions take occur both externally and internally.

In most circumstances, the transformation from montmorillonite into montmorillonite powder involves a process that involves increasing dehydration and a phase change. Developing into a clay that is more durable and long-lasting. The quantity of water that may be lost or acquired by various kinds of clay may cause the specific gravities of certain clays to change in an unpredictable manner. The large majority of the many kinds of clay that can be discovered are found in nature as mixes that contain many different kinds, such as carbonates, feldspars, micas, and quartz. This is true for the vast majority of the clay that can be found.
