Yuan Lei | Kaolin Series-Calcined Kaolin (Special for Paint and Ink)


Calcined kaolin (special for paint and ink)



Performance:Kaolin is a non-metallic mineral, which is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, also known as white earth.


Features:Due to the high purity of kaolinite, the content of harmful elements is very low, so not only the treatment process is simple, but also the whiteness of the product is high, the average whiteness can reach 93%, the highest whiteness can reach 97%, used in papermaking can improve the whiteness of coated paper, instead of some titanium dioxide, can reduce costs. The viscosity concentration is high, up to 74%, the dispersion is good, the covering rate is strong, and it has good compatibility with natural and synthetic adhesives and other additives in the formula, which can make the coating have good rheological properties, especially suitable for coating machine with high solid content. The abrasion value is low, the material is heated evenly, and local over-burning will never occur. The tested abrasion value is only 3.6mg/2000 times.


Scope of application:Suitable for high-grade paint, paint, ink, rubber, plastic, wire and cable, etc.

1. Papermaking, coating can replace some expensive titanium dioxide.

2. Paint, water-based latex coatings.

3. Rubber and special cable reinforcing agent, industrial plastic functional filler, ink, food, medicine, cosmetics filler.

4. Advanced porcelain and special ceramic raw materials.

Yuanlei Classroom | As a key material, how many applications does precipitated barium sulfate have?


The appearance of precipitated barium sulfate is a white amorphous powder, with a relative density of 4.50 (15 ℃) and a melting point of 1580 ℃. Due to its high refractive index (1.63-1.65), it exhibits a relatively white color and a certain degree of covering power. It is almost insoluble in water, ethanol, and acid, soluble in hot sulfuric acid. It is easy to form mixed crystals with potassium permanganate, calcium carbonate, or metal nitrates, and can be reduced to barium sulfide with carbon at high temperatures.

Yuan Lei's Little Knowledge | Application of Wet Mica Powder in Other Fields


Wet mica powder is a high-quality mineral filler made from high-quality mica raw materials, which are washed, impurity removed, soaked, crushed, low-temperature dried, and screened. Its unique production process maximizes the preservation of mica's sheet-like structure, large diameter to thickness ratio, high refractive index, high purity, high whiteness, high gloss, low sand and iron content, and other industrial characteristics that cannot be compared to dry process technology. The unique performance of wet mica powder has greatly improved its application in multiple industries such as plastics, paint, rubber, etc., and has a significant effect on improving product performance and reducing costs.

Yuan Lei's Little Knowledge | Application of Wet Mica Powder in Resin and Plastics


Wet mica powder is a high-quality powder with good whiteness, large diameter to thickness ratio, smooth surface, and uniform particle size obtained by special processes of crushing, drying, and grading mica fragments after washing, impurity removal, and purification. It is widely used in rubber, plastics, coatings, paints, cosmetics, and other industries.
