What factors are related to the quality of talc powder

Release time:2021.06.09

Many people think that the higher the price of the product, the better the quality, in fact, it is not, the quality of the product is related to many factors, below, let's look at the quality of talc powder and what is related to it。

  The higher the purity, the better the enhancement effect, other mineral impurities in talc, metal minerals, etc., the anti-aging function of plastics is very significant。

  Wet whiteness and hue talc by mixing with plastic, will make different degrees of color change, dark plastic products to add Baidu is not too high requirements, but in order to make light products have a good color, so talc powder presented wet whiteness, hue。

  The price of talc powder is an important index to measure the quality of talc powder, and the products are selected according to the functional requirements of different fabrics。If talcum powder with high silicon content should be added to the film, the particle size is small and the particle size is narrow。In this way, the film will have a higher light transmittance, and there will be great changes in tensile strength, puncture resistance and other indicators。The silicon content in injection molding, plate and bar should be low, so the price of talc powder will be low, but it is rich in resources。

  Fluidity in the extrusion process than other granular inorganic data poor fluidity, dispersion difficulties, screw torque, so should choose a better activation agent, which is the key to overcome the above problems。

  Electrostatic talc has a layered structure, large specific surface area, irregular particle shape and convex and concave surface morphology increase its friction coefficient。Therefore, it is easier to generate static electricity, so that the agglutination between the fine particles is completed, and the application effect is affected。

  The above is the main content of what factors are related to the quality of talc powder。
