Do you know the physical characteristics and usage effects of talcum powder?

Talcum powder has the characteristics of soft texture, low abrasion, good chemical stability, high reflectivity, and good hydrophobicity. Haicheng talcum powder manufacturers can improve the mechanical properties of paper, reduce monotonous costs, and improve printing effects.

In fact, many experiments have proved that paper produced with talcum powder not only has a very smooth appearance. It is delicate and comfortable to use, and the storage time is relatively long. Because ordinary paper generally rots when it gets damp, and talcum powder is used, so it is not easy to get damp, so the storage time will be relatively long.

After adding modified talcum powder, the impact toughness is significantly improved, the rheological properties are adjusted, and the flexural modulus and tensile yield strength are also improved. Talcum powder is often used in the process of filling polypropylene. Due to its layered structure and flake structure, talcum powder with finer particle size can be used as a reinforcing filler for polypropylene.

Physical characteristics and usage effects of talcum powder

Modified talcum powder uses specific modifiers to modify the surface of talcum powder through specific process engineering, and has more advantages in use. Due to its layered crystallization, it has excellent physical and chemical properties such as lubricity, non-adhesiveness, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inertness, good covering power, softness, good luster, and strong adsorption. The structure of talc is easy to split into scales and has special lubricity. If the content of Fe2O3 is high, the overall insulation will be reduced.

Talc is soft in texture, with a Mohs hardness coefficient of 1-1.5 and a slippery feel. The cleavage is very complete and it is easy to split into thin slices. The natural repose angle is small (35°–40°). The surrounding rock is silicified slippery magnesite, magnesite, lean ore or dolomitic marble. Except for a few that are moderately stable,
