The ceramic industry is the earliest and most widely used industry for the application of kaolin. The general dosage is 20% to 30% of the formula. The role of kaolin in ceramics is to introduce Al2O3, which is conducive to the formation of mullite, improving its chemical stability and sintering strength. During sintering, kaolin decomposes into mullite, forming the main work of green body strength, preventing the deformation of products, widening the firing temperature, and also making the green body have a certain whiteness. At the same time, kaolin has certain plasticity, cohesiveness, suspension and bonding ability, which endows porcelain clay and porcelain glaze with good formability, making porcelain clay body conducive to turning, grouting and forming. If used in wires, it can increase insulation and reduce dielectric loss.
Compared with uncalcinated kaolin, low-temperature calcined kaolin has a reduced bound water content, an increase in silica and alumina content, an increase in active sites, a change in structure, a smaller and more uniform particle size. Compared with uncalcinated kaolin filled NR rubber, low-temperature calcined kaolin filled NR rubber has basically the same vulcanization characteristic curve, with unchanged Shore A-type hardness and increased tensile strength, Both physical properties meet the requirements of the industry standard for non transparent sports shoe soles.

Barium sulfate is used in latex paint and is known as "acid resistant" latex paint. Even when exposed, it has acid resistance. The dispersibility, optical rotation retention, and flowability of barium sulfate can enhance its chemical properties.
Barium sulfate is superior to most other filling powders and has characteristics such as low cohesion, low light dispersibility, and fine particles. Barium sulfate is particularly suitable for pigment topcoats, varnishes, spray paints, etc. It has chemical resistance and weather resistance. It is inert, insoluble in organic mediators such as water, acid, and alkali, and its excellent glossiness and particle fineness enable the topcoat to be maintained during long-term exposure. Barium sulfate is recommended for topcoats to increase surface hardness and color stability.

Sericite powder has fine and smooth feeling, stable chemical performance, strong adhesion, good dispersion, uniform mixing with water and glycerin, silky luster, UV resistance and other excellent characteristics, and is a high-quality raw material for various cosmetics in the beauty cosmetics industry. Due to its delicate texture, elasticity, suitable glossiness, high whiteness, and minimal or no heavy l elements such as lead and mercury, it can meet the special requirements of some high-end beauty cosmetics.
Sericite, with its unique fine scale structure and silk luster, can significantly improve the optical properties of plastic products, improve the air tightness, rigidity, heat resistance and dimensional stability of plastic products when it is used as a reinforcing filler in the plastic industry, which is also the difference between sericite and other inorganic fillers.
In the rubber industry, sericite is a good filler or extender, which can reduce the rubber content of materials and thus reduce production costs. Sericite has a unique sheet structure, which can effectively improve the damping performance of rubber. Its good compression resistance, tensile resistance, light resistance, fire resistance, weather resistance, heat resistance, acid resistance and electrical insulation physical and chemical properties can improve the mechanical properties, heat resistance, aging resistance and other functions of rubber products with sericite added, and can be used in the development of special rubber products.

National Bureau of Statistics: Promoting a higher level of dynamic balance between supply and demand, and improving the healthy development of industry
Ultra fine sericite powder is a new type of functional filler, which is widely used in the field of paints and coatings. Because sericite powder is in the form of fine flakes, smooth crystal surface, large diameter thickness ratio, high whiteness, stable chemical performance, light weight, smooth, insulation, and radiation resistance, it is a good filler for various high-grade paints, rust prevention, fire prevention, and anti-corrosion coatings. Due to the ed structure of sericite, the dye particles enter the lattice of sericite, which can keep the paint film from fading for a long time.
Polypropylene fiber woven bags have widely replaced jute woven sacks and become the most important basic packaging materials for grains, industrial raw materials, fertilizers, food, mineral sand, and coal. Their forms have long evolved from traditional pillow ladder style to barrel and column style. Due to its low density, light weight, conformability, and easy storage, it has even replaced some small containers.
