Anti-slip powder and talcum powder read almost, some people may ask talcum powder is not anti-slip powder? Is the white powder used by athletes. so let's take a look at what is the difference between slip powder and talcum powder.

 

 

Anti-skid powder is a kind of harmless to the human body, which can quickly absorb sweat and increase the friction of the contact surface of the object. It is used to prevent sports accidents caused by unstable standing and grasping.

The chemical composition of the anti-skid powder is magnesium carbonate (xMgCO3 · yMg(OH)2 · zH2O ), and the ph value is weak alkaline, white and non-toxic.

The anti-skid principle:

The reason why anti-slip powder is non-slip is determined by the physical properties of its main component magnesium carbonate. Magnesium carbonate is a macromolecular substance, because of its large molecular volume, the contact area with the object is large, so the static friction force of the contact surface is large, and the static friction force between the contact objects is not easy to slide.

Magnesium carbonate is characterized by strong water absorption, the main principle of the use of non-slip powder is to absorb the sweat on the hands, keep the palm dry, play the role of non-slip. Anti slip powder is also known as sports magnesium powder, anti slip magnesium powder.

 

 

Talcum powder and non-slip powder appearance looks little difference, white powder.

However, the main component of talc is magnesium silicate containing water, and the molecular formula is Mg3[Si4O10](OH)2. Talc is monoclinic. The crystals are pseudo-hexagonal or rhombohedral flakes, occasionally. Usually dense massive, leaf-like, radial, fibrous aggregates. Colorless transparent or white, but with a small amount of impurities and light green, light yellow, light brown or even light red; cleavage surface was pearl luster. Hardness 1, specific gravity 2.7~2.8.

◆ Basic characteristics:

Talc has excellent physical and chemical properties such as lubricity, anti-adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, soft, good gloss, and strong adsorption.

Talc is soft, its Mohs hardness coefficient is 1~1.5, with slippery feeling, extremely complete cleavage, easy to split into thin slices, small natural resting angle (35 ° ~ 40 °), extremely unstable, the surrounding rock is silicified and talcated magnesite, magnesite, lean ore or dolomitic marble, except for a few moderately stable, generally unstable, with developed joints and fissures, the physical and mechanical properties of ore and surrounding rock have a great influence on the mining process.

 

 

The scope of application

Talcum powder has a wide range of applications, mainly used in cosmetics (talcum powder, foundation, etc.), medicine, food (food additives), coatings, paper, plastics, rubber, cables, ceramics, waterproof materials, and fine talcum powder.

It can be seen that non-slip powder and talcum powder are not the same thing, each has its own purpose.

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. It is named after Gaoling Village, Jingdezhen, Jiangxi Province.
