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.

01. Application in molds

Coating a formula containing mica powder on the surface of the molding sand mold (including the use of a mold washing agent containing mica powder) can seal the micropores on the mold surface, improve demolding performance, and enhance the surface smoothness of the product.

02. Application in lubricants

For example, used in metal rolling. The pressure of metal rolling is very high. If only liquid lubricant is used, the lubricant at the force point may be completely squeezed out, resulting in a "dry friction" state, which is very harmful (mold wear, rough surface of the product, increased power consumption, etc.). Adding solid lubricants is an effective solution. Extreme pressure lubricants often use solid lubricants to prevent dry grinding (which can cause bearing redness, sintering, and unimaginable consequences). This type of mica powder has high requirements for the surface smoothness and purity of the chip. If it contains impurities such as quartz sand, it will actually accelerate wear.

03. Application in cosmetics

Mica is a natural mineral product with extremely high chemical stability and is a completely inert substance, making it safe, non-toxic, and harmless, suitable for the requirements of cosmetics. Mica chips have a strong pearlescent luster, especially when the particle size is appropriate, they can be used to replace or partially replace expensive pearlescent pigments, enhancing the luster effect of cosmetics. Moisture cannot penetrate mica chips, and when used in moisturizing products, it can inhibit the evaporation of skin moisture.

Mica chips can shield against ultraviolet and infrared rays, making them excellent anti UV agents for cosmetics. Due to its pure nature, non-toxic and harmless nature, it has advantages that synthetic organic anti UV agents do not possess. Due to the extremely thin and strong coverage ability of the chips, only a small amount of these products are needed to form a layer of invisible UV protection and brightening agents on the skin surface.

Mica particle chips are extremely thin, with a thickness usually only a few tens of nanometers. The ratio of chip diameter to thickness (diameter to thickness ratio) is as high as 80-120 times, and the covering power is extremely strong.

04. Application in special powders

Mica powder, if coated with conductive substances (metals, metal oxides) on the surface, generates conductive powder, which is used to manufacture conductive and anti-static polymer materials. If coated with zinc phosphate, it is a corrosion-resistant filler for the coating.

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.
