Talc silicate minerals have a slimy hand feel

Modern industrial manufacturing; For example, in paper making, the amount of talc added by kaolin (or calcium carbonate) in high-grade copper paper is as high as 40%. Also like plastic products, the amount of modified talc powder can be up to 30%-50% depending on the product requirements. Some PVC products have been added up to 70%. Talc powder is used in plastics, rubber, electronics, cables, paints, coatings, abrasives, pharmaceuticals, cosmetics, ceramics, building materials, food processing and household appliances.

Talc is a hydrothermal alteration mineral, and magnesium-rich mineral is often changed into talc by hydrothermal alteration. Haicheng talc is a common silicate mineral. It is very soft and greasy. Ten minerals have been selected to represent 10 hardness levels, known as mohs hardness, in which the first, or softest, is talc.

Soft talc can draw white marks instead of chalk. Talc is usually lumpy, bladed, fibrous or radial in color of white, grayish white, and may have a variety of colors due to the presence of other impurities. Talc can be used for many purposes, such as fireproofing, paper making, rubber packing, pesticide absorbent, leather coating, cosmetic materials and carving materials.

In addition to the above general use, talc powder also has a life small wonderful use - talc powder can be used to dissolve the door seal stick knot

The rubber parts of the car body will gradually age with the increase of the service life of the car. If you open the door after rain, there will often be an unsmooth and "creak" sound. In fact, this is the door sealing rubber ring signs of aging. In this case, a handful of talc powder can be applied to the rubber seam in the door, which can immediately restore the surface of the seal rubber strip smooth, so that the door open and close freely, no more noise. This method is applicable to home refrigerator, freezer door seal noise.

Talc powder, as an additive, modifying agent or filler, has been widely used in papermaking, painting, coating, ceramics, chemical industry, daily chemical industry, plastics, rubber, food, medicine and other industries. Talc has the advantages of soft texture, low abrasion, high gloss, low oil absorption and good transparency.

Talc powder has four advantages: enhancement, heat preservation, barrier, nucleation and aging resistance. This is why talc can stand out in many fillers.

The remarkable enhancement effect of reinforced talc on plastic products is mainly due to its unique micro-lamellar structure. After processing talc powder, the more complete the lamellar structure remains, the more obvious its enhancement effect. The larger diameter to thickness ratio (the ratio of the average diameter of sheet particles to their thickness) can improve the rigidity, impact strength, bending modulus and thermal stability of plastic products. For example, bumper, automobile interior decoration, etc.
