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. Next, let's take a look at what the quality of the stone powder is related to.
The higher the purity, the better the strengthening effect. Other mineral impurities and metallic minerals in talc have a significant anti-aging function on plastics.
After the wet whiteness and hue talc is mixed with the plastic, the color will change to different degrees. The Baidu added to the dark plastic product is not too demanding, but in order to make the light-colored product have a good color, talc powder is only Presents wet whiteness and hue.
The price of talcum powder is an important indicator to measure the quality of talcum powder. Products are selected according to the functional requirements of different fabrics. If talc powder with higher silicon content should be added to the film, the particle size is small and the particle size distribution is narrow. Only in this way can the film have a higher light transmittance, and there will be huge changes in the tensile strength, puncture resistance and other indicators. The silicon content in injection molding, plates, and bars should be low, so the price of talc will be lower, but the resources are abundant.
In the extrusion process, the fluidity is worse than other granular inorganic materials, the dispersion is difficult, and the screw torque is larger. Therefore, a better activator should be selected. This is the key to overcoming the above problems.
Electrostatic talc has a layered structure, with large specific surface area, irregular particle shape, and surface convex and concave morphology, which increase its friction coefficient. Therefore, it is easier to generate static electricity, so that the aggregation of fine particles is completed, and the application effect is affected.
The above is the main content related to the quality of talcum powder.
