Characteristics of conventional powders in the chemical industry

Characteristics of talc powder

Talcum powder, whose main component is hydrated magnesium silicate, is a white or off-white fine sand-free powder. It has excellent physical and chemical properties such as lubricity, fire resistance, acid resistance, insulation, high melting point, and chemical inertness.

Characteristics of kaolin clay

Kaolin, also known as dolomite, is a non-metallic mineral mainly composed of clay minerals of the kaolinite family, forming clay and clay rock.

In terms of chemical properties, kaolin has excellent electrical insulation properties, good acid solubility resistance, very low cation exchange capacity, high refractoriness and other physical and chemical properties.

Characteristics of mica powder

Mica powder is a non-metallic mineral whose main components are silica and aluminum oxide.
In terms of chemical properties, mica powder shows good acid and alkali corrosion resistance, high temperature resistance and other properties. In addition, plastic mica powder processed through special processes has the characteristics of high diameter-to-thickness ratio, high temperature resistance, acid and alkali resistance, and wear resistance. It is a natural functional powder filling material.

Characteristics of silica powder

Microsilica powder is a fine granular solid material with a particle size generally less than 1 micron. It is a new functional mineral raw material composed of natural microcrystalline quartz (a-quartz). It is mainly white or off-white.
Microsilica powder has a series of excellent properties: low thermal expansion coefficient, excellent dielectric properties, high thermal conductivity and good suspension performance.

Characteristics of aluminum hydroxide

In the chemical industry, aluminum hydroxide is mainly used as a flame retardant. It is not only flame retardant, but also prevents smoke, dripping, and toxic gases. Therefore, it has been widely used in electronics, chemicals, cables, plastics, rubber and other industries. In particular, ultrafine aluminum hydroxide has become the most widely used and widely used low-smoke, halogen-free material due to its multiple functions such as flame retardancy, smoke suppression, filling, and environmental protection.

Characteristics of alumina

Aluminum oxide, with the chemical formula Al2O3, is an inorganic substance. It is a compound with high hardness and a melting point as high as 2054°C. It is a typical ionic crystal and can be ionized at high temperatures.

Chemically, alumina is a highly hard material with a Mohs hardness of up to 9, which makes it widely used as a wear-resistant and corrosion-resistant material in many applications. Alumina has good thermal conductivity, and Al2O3 with high purity requirements is generally prepared by chemical methods.
In terms of industrial applications, aluminum oxide is widely used in the materials industry due to its high hardness, wear resistance and corrosion resistance.

Characteristics of barium sulfate

Barium sulfate is a colorless orthorhombic crystal or white amorphous powder with stable chemical properties and insoluble in water, acid, alkali or organic solvents. Barium sulfate is made from barite as the main raw material, and is processed through a series of processes such as mineral processing, mineral washing, and crushing.

Characteristics of diatomite

Diatomaceous earth is a naturally occurring inorganic mineral with colors such as white, off-white, gray and light gray brown, and has the characteristics of fine, loose, light and porous. It has very strong water absorption and permeability, so it is often used as a filler or anti-settling agent in paint, coating, rubber, plastic and other industries.

Diatomite also has good stability and is an important industrial material for heat insulation, grinding, filtration, adsorption, anticoagulation, demoulding, filling, carrier, etc.

Bentonite characteristics

Bentonite, also known as bentonite, bentonite or bentonite, is a non-metallic mineral whose main mineral component is montmorillonite.
The color of bentonite is usually white or light yellow, but due to changes in iron content, it may also appear light gray or light green.

Characteristics of transparent powder

Transparent powder is a new type of functional filler. It is a composite silicate. Its main component is a composite silicate containing magnesium, aluminum and calcium, which is an inorganic salt. Its characteristics are as follows:
1. High transparency
2. Good hardness and gloss
3. Low oil absorption
4. Good collapse resistance and less dust during use.
5. Ultra-transparent ultra-fine powder material is developed through the process of raw material selection-mixing-melting-rough grinding-fine grinding-grading.
