Study on the application of brucite powder with different mesh sizes in PVC sheets

As a high magnesium non-metallic mineral, brucite has shown wide application potential in many fields due to its unique physical and chemical properties. Especially in the plastics industry, brucite powder of different mesh sizes is used as filler in PVC (polyvinyl chloride) sheets, which can significantly improve the performance of the material. The following is an overview of the key points for the application of brucite powder in PVC sheets:

Properties and Applications of Brucite Brucite, also known as brucite, is a layered hydroxide with high magnesium content and excellent physical and chemical properties. It exists in nature with high purity and is widely used in fire retardant coatings, paper industry, preparation of magnesium oxide and magnesium chloride, environmental protection and other fields.

Preparation and modification of brucite powder The preparation of brucite powder usually involves the crushing and ultrafine grinding of the ore. Through ultra-fine grinding technology, brucite powders of different mesh sizes can be obtained. These powders have undergone surface chemical modification to improve their dispersion and compatibility in polymer materials.

Application in PVC sheets

Improve mechanical properties: Brucite powder as a filler can enhance the mechanical strength and hardness of PVC sheets and improve its wear resistance.

Improve thermal stability: The addition of brucite powder can improve the thermal stability of PVC materials and delay the thermal decomposition process, thereby increasing the service life of the material.

Enhanced flame retardant properties: Brucite powder has good flame retardant properties and can be used as a flame retardant for PVC materials to improve its fire safety.

Adjust optical properties: Brucite powder of different mesh sizes can affect the gloss and transparency of PVC flakes. By adjusting the particle size distribution of the filler, the optical properties of the material can be controlled.

Environmentally friendly advantages of brucite powder As a natural mineral filler, brucite powder is environmentally friendly. It not only has a small impact on the environment during the production process, but also does not produce harmful volatile substances during the use of the material, which meets the requirements of modern environmentally friendly materials.

The application of brucite powder of different mesh sizes in PVC sheets not only improves the physical and chemical properties of the material, but also meets environmental protection and safety requirements. With the continuous advancement of material science and processing technology, the application prospects of brucite powder in PVC materials will be broader
