What is the right talc grinding mill machine?

Talc powder, as an additive, modifier or filler, has been widely used in papermaking, paint, coating, ceramics, chemical industry, daily chemical industry, plastics, rubber, food, medicine and other industries. Talc has the advantages of soft texture, low wear, high gloss, small oil absorption value, good transparency, etc.

Talc powder has four advantages: enhancement, heat preservation, barrier, nucleation and aging resistance. This is why talcum powder can stand out among many fillers.

1、 Enhancements

The remarkable reinforcing effect of talc on plastic products mainly comes from its unique micro lamellar structure. Talc powder processed by talc grinding mill produced the more complete the flaky structure is, the more obvious the strengthening effect is. The rigidity, impact strength, bending modulus and thermal stability of plastic products can be improved by a large diameter thickness ratio (the ratio of the average diameter of flake particles to its thickness). For example, bumper, automobile interior trim, etc.

2、 Thermal insulation and isolation

High quality superfine talc powder is in sheet structure, which can be evenly dispersed in the resin in layers when used in plastic products. Like the metal structure mesh embedded in cement products, it can maintain the advantages of plastics, form a reinforced support form with excellent mechanical properties, improve the physical properties of plastic products, and also have obvious thermal insulation and barrier effects.

3、 Nucleation

The talc is very slippery. Adding talc powder processed by talc grinding mill can obviously improve the plastic opening, and also can improve the anti adhesion of the film. When superfine talc powder (1μBelow m) can play the role of nucleating agent when uniformly dispersed in the plastic matrix, such as in PET plastics.

4、 Aging resistance

Talc, mica, kaolin and other silicon (Si) containing minerals have the barrier properties of infrared ray and ultraviolet ray. Talc powder processed by talc grinding mill has obvious heat preservation, aging resistance and other effects in plastic
