Organoclay in Paint coatings

Organoclay in Paint : Jedna od primarnih uloga suspendirajućeg sredstva je osigurati da krute komponente boje ostanu ravnomjerno suspendirane kroz formulaciju. Bez odgovarajućeg suspendirajućeg sredstva, čestice boje se talože na dnu posude, što dovodi do neravnomjerne raspodjele i mogućih problema sa stvrdnjavanjem. Organoclay učinkovito rješava ovaj problem u proizvodnji boja osiguravajući potrebnu viskoznost i granicu tečenja kako bi se čestice boje raspršile i spriječilo njihovo taloženje.

ORGANOGLINA:

Our Five-Star Treatment Media

Your first choice for removing organic contaminants from water or sediment, the ORGANOCLAY product range provides formulations to meet almost any adsorption application.

Used and trusted worldwide, it’s proven to work efficiently and effectively.

A little goes a long way – and reduces costs

ORGANOCLAY’s substantial adsorption capacity not only reduces necessary cap thickness compared to a conventional sand cap but can also extend cap life—in some circumstances, for years—and reduce overall costs.

Because ORGANOCLAY can be used as a pre-treatment to Granular Activated Carbon (GAC), ORGANOCLAY can increase overall efficiency by preventing surface pores in GAC from blinding.

The ORGANOCLAY Product Range

Powerfully adsorbant ORGANOCLAY is available in multiple formulations to best mitigate water and sediment contamination in a variety of specific conditions:

ORGANOGLINA: Our coarsest grain media, ORGANOCLAY is a larger and denser version of ORGANOCLAY CP-200 to aid in settling through the water column. When used for sediment capping, ORGANOCLAY can be placed hydraulically or mechanically.

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.

Prijave

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.

Što je 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, bentonitna glina, 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, tj. dissolved metals) or anions (negatively charged ions, tj. phosphate, nitrate). The bilayer that contains hydrophobic chains will capture non-polar organics such as benzene.

Illustration of How Organoclay Works

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, mast, tinte, oil drilling fluids, rheological products, kozmetika, 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. Tipično, 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 (tj. granular activated carbon, organoklana, 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. Tipično, pollutants found in stormwater are monitored by state regulators to ensure we have clean lakes, rijeke, 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.

Svojstva & Markets

Boje & Premazi : 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.

Kozmetika : 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.

Tekućine za bušenje : 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 :

Increased Modular Strength without Sacrificing Impact Resistance
Improved Gas Barrier Properties
Increased Solvent and Heat Resistance
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.

Međutim, 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, međutim, 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.

Što je organofilna glina?

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, uključujući tekućine za bušenje, boje, i kozmetike.

[Tekućine za bušenje]

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.

Prijave

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 do 10 lbm/bbl [5.7 do 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 do 15 lbm/ bbl [28.5 do 43 kg/m3] range.

Prednosti

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. Spremnik držati zatvoren. 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.

Organofilna glina

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.

Primjena

Organophilic clay is a self-activating gallant offering rapid yield development, visoke čvrstoće gela, i povećanu učinkovitost.

Organoclay u boji kao suspendirajuće sredstvo

Organoclay in Paint : Povećanjem viskoznosti boje, organska glina pomaže u postizanju željenog tečenja i svojstva izravnavanja. Ova kontrola viskoznosti neophodna je za nanošenje boja, budući da utječe na čimbenike kao što je mogućnost četkanja, otpornost na kapanje, i formiranje filma. Prisutnost organogline omogućuje gušću konzistenciju boje, omogućujući bolju kontrolu tijekom primjene i smanjujući pojavu kapanja ili curenja.

Organoclay se može koristiti u raznim vrstama boja, uključujući sustave na bazi vode i otapala, pružanje stabilnosti u različitim medijima. Ova prilagodljivost čini Organoclay preferiranim izborom za proizvođače boja koji traže pouzdana suspendirajuća sredstva.

Organoclay in Paint & Premazi

Organoclay je vrijedna komponenta u formuliranju boja i premaza na bazi vode i otapala. Njegova uporaba u postizanju stabilnih emulzija doprinosi poboljšanoj stabilnosti, reologija, i ukupnu izvedbu konačnog proizvoda boje.

Organoclay u bojama i premazima na bazi vode

Voda je uobičajeni medij koji se koristi u bojama na bazi vode, a održavanje odgovarajuće razine pH bitno je za optimalnu učinkovitost. Tipično, pH raspon od 7.0 do 8.0 smatra se idealnim za boje na bazi vode. Organoklina se može dispergirati u vodi unutar tog pH raspona.

Tijekom procesa proizvodnje boje, raspršivanje sastojaka velikom brzinom tijekom razdoblja od 20 do 30 minuta je često potrebno. Ovo raspršivanje velikom brzinom pomaže u razbijanju nakupina i postizanju homogene smjese.

Kod formuliranja boja na bazi vode, emulzije se obično koriste za raspršivanje veziva i drugih komponenti. Pravilno miješanje emulzija bitno je za osiguranje stabilnosti i učinkovitosti boje. Korištenje organogline u bojama na bazi vode omogućuje formulatorima naknadnu korekciju. Prilagodbe se mogu izvršiti ugradnjom dodatnih aditiva ili modificiranjem količine organogline kako bi se postigli željeni rezultati.

Boje i premazi na bazi otapala

Boje i premazi na bazi otapala tekući su zaštitni slojevi koji se prvenstveno sastoje od organskih spojeva. Naširoko se koriste za zaštitu raznih materijala’ površine od korozije, pružajući trajnost i estetsku privlačnost. Bentonitna organska glina može ponuditi vrijedne prednosti u formulacijama boja na bazi otapala, posebno u pogledu zaštite od vremenskih uvjeta i pokrivanja kvarova.

Bentonit organoglina služi kao punilo, pomaže u popunjavanju malih nesavršenosti, pukotine, ili površinske nepravilnosti, što rezultira glatkijim i estetski ugodnijim završetkom. Organoclay služi kao dragocjeno disperzijsko sredstvo u bojama i premazima na bazi otapala, posebno u primjenama koje uključuju akrilnu smolu. Ravnomjerno raspršuje akrilnu smolu kroz formulaciju boje za jednoliku raspodjelu.

Studije o organoglini u materijalima za lakiranje

Čvrstoća premaza na udar odnosi se na njegovu sposobnost da se odupre oštećenjima i deformacijama kada je izložen vanjskim silama, poput udara ili sudara. Premazi od polistirena naširoko se koriste u raznim industrijama zbog svojih izvrsnih toplinskih i mehaničkih svojstava.

Ugradnjom aditiva na bazi organske gline u polistirenske premaze, dolazi do značajnog poboljšanja u udarnoj snazi. Organoclays se sastoji od slojevitih mineralnih struktura modificiranih organskim surfaktantima. Posjeduje jedinstvena svojstva koja mogu ojačati matricu premaza. Interkalacija organoglina unutar polimerne matrice povećava sposobnost materijala da apsorbira i distribuira energiju od udaraca, čime se povećava njegova otpornost na udarce.

Kohezijska čvrstoća premaza ključna je za njegovu trajnost i dugovječnost. Aditivi na bazi organske gline pokazali su sposobnost povećanja kohezijske čvrstoće polistirenskih premaza. Uključivanje organoglina u formulaciju premaza poboljšava međupovršinsko vezivanje između polimerne matrice i punila. Ova poboljšana kohezija pomaže u smanjenju pucanja, raslojavanje, i drugi oblici kvara premaza.

Teksturirane boje i boje u debelom sloju

Organoclays nudi uvjerljive karakteristike protiv taloženja i pridonosi dugotrajnoj stabilnosti skladištenja teksturiranih boja i boja nanesenih u debelim slojevima. Ovi dodaci pomažu u razvoju jake elastične strukture koja sprječava ili kontrolira taloženje pigmenata.

Jedan od razloga zašto su gline i organokline učinkovite u borbi protiv taloženja je njihova sposobnost da razviju jaku elastičnu strukturu kada miruju. Ova struktura djeluje kao barijera i sprječava taloženje pigmenata tijekom vremena. Stvaranjem mreže čestica, gline i organogline održavaju suspenziju pigmenata i sprječavaju njihovo taloženje na dno posude.

Važno je postići pravu ravnotežu u reološkim svojstvima organoklina u formulaciji boja. Dok je visok modul skladištenja poželjan kako bi se spriječilo taloženje, ne smije biti previsoka jer može dovesti do sinereze. Sinereza je odvajanje tekućine od gela ili polukrutog materijala, što rezultira stvaranjem sloja tekućine na površini.

Organska modifikacija bentonita i njezin učinak na reološka svojstva

Kao što je prije spomenuto, bentonit je mineral gline koji se pretežno sastoji od montmorilonita, poznat po svojoj sposobnosti bubrenja i formiranja gelastih struktura kada se rasprši u vodi. Ponekad njegova reološka svojstva možda nisu prikladna za određene primjene. Zbog toga je bentonitna glina modificirana kako bi se pretvorila u bijeli praškasti oblik koji se zove organoclay.

Proces organske modifikacije uvodi hidrofobne skupine na površinu gline, što dovodi do poboljšane disperzibilnosti i kompatibilnosti s organskim otapalima ili vezivima. Organski bentoniti djeluju kao sredstva za zgušnjavanje, povećanje viskoznosti formulacije premaza. Ova poboljšana viskoznost pruža bolju kontrolu nad protokom i izravnavanjem premaza tijekom nanošenja za jednoliku pokrivenost i smanjenje vjerojatnosti kapanja ili curenja.

Organocline bentonit je okarakteriziran kao pseudoplastična tekućina. Pokazuje ne-Newtonovsko ponašanje. Zbog toga se viskoznost smanjuje kako se brzina smicanja povećava. Ovo svojstvo omogućuje lakšu primjenu i širenje premaza tijekom procesa bojanja ili premazivanja. Ponašanje pseudoplastičnog tečenja osigurava glatko tečenje premaza pod smičnim naprezanjem, olakšavajući stvaranje ravnomjernog i tankog sloja premaza na površini papira.
