Talc

We are offering talc.
【product presentation】 \rtalc\'s main component is hydrous magnesium silicate, formula mg3[si4o10] (oh) 2. Talc is monoclinic.\rcrystal was pseudohexagonal crystal or diamond flake, occasionally. Typically a dense block, leaf-\rshaped, radial, fibrous aggregates. Colorless or white, but with a small amount of impurities present\rlight green, light yellow, light brown or reddish; cleavage surface pearly luster. Hardness 1, specific\rgravity 2.7 to 2.8. Talc has a lubricating, anti-adhesion, flow aid, fire resistance, acid resistance,\rinsulation resistance, high melting point, chemically inert, good hiding power, soft, shiny, strong\radsorption and some other excellent physical and chemical properties, as talc the crystal structure is\rlayered, therefore have a tendency to split into scales and a special lubricity easily, will reduce its\rinsulation if in a high content of fe2o3.\r\r【specification 】 \rtalc physical properties:\rname talc powder grade premium grade\rfineness 1250(mesh) origin hebei \rsio 60% allow error ±0.01kg\rmgo 30% whiteness 93 200 mesh, 325 mesh, 500 mesh, 600 mesh, 800 mesh, 1250 mest, etc.\r\r【usage】 \rchemical grade talc\ruses: used in rubber, plastics, paints, and other chemical industries as a reinforcing filler modification. \rfeatures: increasing the stability of the product shape, increased tensile strength, shear strength,\rflexural strength, compressive strength, lower distortion, stretching rate, thermal expansion coefficient,\rhigh whiteness, uniform size dispersion and other characteristics.\r\rceramic grade talc\ruses: used in the manufacture high frequency porcelain, ceramic radio, all kinds of industrial\rceramics, building ceramics, ceramics and pottery glaze. \rfeatures: high temperature does not change color after calcination enhanced whiteness, density,\rgood gloss, smooth surface.\r\rcosmetic grade talc\ruses: it is the quality filler in cosmetics industry.\rfeatures: contains a lot of silicon element. It has a barrier effect of the infrared, thus enhancing the\rcosmetic sunscreen and anti-infrared performance.\r\rpharmaceutical, food-grade talc\ruses: used in medicine, food additives industry. \rfeatures: non-toxic, odorless, white high, good capacitive, high gloss, soft taste, smoothness strong\rfeatures. Ph value is 7-9, does not degrade the characteristics of the original product.\r\rpaper grade talc\ruses: used in a variety grades of paper industry producing. \rfeatures: paper powder has high whiteness, particle size and stability, and low degree of wear. Use\rthis powder can create paper to achieve a smooth, delicate, saving raw materials, improve lipid network life.\r\rstephanie at jnmaofeng dot com.
