Монтмориллонитовый порошок

Introduction

A member of the smectite family of minerals, Монтмориллонитовая глина 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.

Химия поверхности и межфазной границы глинистых минералов

Because of its unique chemical composition, бентонит 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.

Бентонит

Bentonite clay vs montmorillonite clay are both types of clay and загуститель. 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.

Физические свойства

Montmorillonite typically has a density ranging from 2 к 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 к 2 по шкале Мооса, 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. Физические свойства монтмориллонита играют решающую роль в его идентификации и классификации в области геологии и материаловедения..

Химические свойства

Он имеет уникальную физическую структуру благодаря своим слоистым листам., которые также определяют его химические свойства. Состоит из двух типов структурных листов.. Это тетраэдрический лист и октаэдрический лист.. Тетраэдрический лист состоит из кремний-кислородных тетраэдров, соединенных друг с другом..

Когда несколько тетраэдров расположены вместе, они делят друг с другом три угла. Это создает сеть, имеющую шестиугольную форму.. Четвертый угол каждого тетраэдра связан с соседним октаэдрическим листом.. 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(Ал,мг)2Си4О10(ОЙ)2·nH2O. It has sodium, кальций, алюминий, магний, кремний, кислород, 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.

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. Кроме того, 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. Повысить термостойкость других материалов можно, включив его в их состав.. Глинистые минералы, такие как монтмориллонит и бентонит, использовались людьми из-за своих теплоизоляционных качеств в различных приложениях, где требуется термостойкость, а также огнестойкость.. Для того, чтобы сделать полимерные композиты более устойчивыми к нагреву и огню., наноглина в настоящее время широко используется и исследуется в качестве потенциальной добавки..

Сорбция воды | Монтмориллонитовый порошок

В ответ на изменения относительной влажности в ближайшем окружении., Частицы монтмориллонитовой глины могут либо поглощать больше воды, либо отдавать часть воды, которую они уже содержат.. Когда вода впитывается, он заполняет пространства, оставшиеся между сложенными слоями силиката.. 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.
