Talc crusher makes talc powder more fully used, and its application in the plastic industry is more than 150000 tons every year, and its scope and application fields have increased sharply. Talc production line can bring more market space for enterprises.
It has the following uses:
1. As a plastic film insulating agent.
Silicon containing minerals such as mica, kaolin and talc have the ability to block infrared rays. Adding an appropriate amount of this mineral powder to the film of agricultural greenhouse can improve the barrier of plastic film to infrared ray, so as to reduce the heat loss of infrared radiation at night and improve the heat preservation performance of greenhouse.
Because talc powder is cheap and easy to operate, its light transmittance and infrared light barrier properties are not as good as mica powder and kaolin, but it can still maintain good light transmittance and improve its insulation. Therefore, it has been widely used in agricultural plastic films. At present, according to the type of membrane (weathering membrane, double membrane, multifunctional membrane, etc), the amount of ultra-fine talc powder used is 2% to 7%.
2. As nucleating agent.
As a nucleating agent for PE or PP, talc requires small particles. The smaller the particle size, the more the number of particles, which means more central crystals, more crystal growth. The smaller the size of the crystal itself, the better the performance of the material. Moreover, the better the dispersion of talc in the molten state, the better the recombination phenomenon.
3. Application in coatings.
Talc powder has good suspension, easy dispersion and low corrosion. In the coating, talc powder as filler can play a role of skeleton, reduce the manufacturing cost and improve the film hardness of the coating. It also has the characteristics of improving the stability of product shape, increasing tensile strength, shear strength, pressure strength, reducing deformation, elongation, thermal expansion coefficient, high whiteness, uniform particle size and strong dispersion. Talc powder with flake particle structure can make the coating have high water resistance and impermeability of enamel paint. Talc powder with fibrous particle structure can improve the rheology and leveling of the coating, and improve the weatherability of the coating at the same time.
