1- Talc classification and uses
a- Chemical grade talc
Uses: used in rubber, plastic materials, paint and other chemical industries as a reinforcing filler modification. Features: increasing the stability of the product shape, increased tensile strength, shear strength, flexural strength, compressive strength, lower distortion, stretching rate, thermal expansion coefficient, high whiteness, uniform size dispersion and other characteristics.
b- Ceramic grade talcum powder
Uses: used in the manufacture high frequency porcelain, ceramic radio, industrial ceramics, building ceramics, ceramics and pottery glaze. Features: High temperature does not change color after calcinations enhanced whiteness, density, good gloss, smooth surface.
c- Cosmetic grade talc
Uses: it is the cosmetics industry quality filler. Features: contains a lot of silicon element. It has a barrier effect of the infrared, thus enhancing the cosmetic sunscreen and anti-infrared performance.
d- Pharmaceutical, food-grade talc
Uses: used in medicine, food additives industry. Features: non-toxic, odorless, white high, can be capacitive good, high gloss, soft taste, smoothness strong features. PH is 7-9 straight, does not degrade the characteristics of the original product.
e- Paper grade talc
Uses: used in a variety of low-grade paper industry products. Features: paper powder has high whiteness, particle size and stability, and low degree of wear. Use this pink paper creates paper can achieve a smooth, delicate, saving atomic material, improve lipid network life.

Determination law |
1- Whiteness: measured by DN-B of Hangzhou high-tech instrument company;
2- Fineness: by laser particle sized distribution analyzer obtains the cumulative percentage of median;
3- Lose weight: Jls-k5101 law, Japan (Tokyo) possession of scientific instruments produced by the loose-determination of specific gravity;
4- Specific surface areas: calculated by the United Kingdom MALVERN company MASTERSIZER laser particle size analyzer;
5- Oil absorption: Determined from Jls-k5101 law, adding flax oil titration until the block;
6- LOI: from test material at temperatures above 1000 ℃ blanch to quantitative determination of reduction;
7- PH value: measured from Italy HANNA company H18520-type PH meter. |
