Surface Coating of Wollastonite - Higher Modification Rate with Atomization Process
Wollastonite, as a filler in the rubber and plastic industry, possesses various functions and advantages in rubber and plastic materials. Some of the key functions include:
Strength Enhancement: Wollastonite, as a filler, can enhance the strength and hardness of rubber and plastic materials, improving their wear resistance and durability.
Increased Hardness and Stiffness: The addition of Wollastonite can increase the hardness and stiffness of rubber and plastic materials, making them more suitable for applications that require high strength and rigidity.
Density Adjustment: As a lightweight filler, Wollastonite can increase the volume of rubber and plastic materials without adding much weight, helping to adjust their density.
Improved Heat Resistance and Chemical Resistance: The addition of Wollastonite can enhance the heat resistance and chemical resistance of rubber and plastic materials, making them more suitable for high-temperature or corrosive environments.
Enhanced Processing Performance: Wollastonite, as a filler, can improve the processing performance of rubber and plastic materials, including increasing the efficiency of extrusion, injection molding, and forming processes.
Cost Reduction: Compared to some other fillers, Wollastonite may be a relatively inexpensive filler, helping to reduce manufacturing costs. When directly adding Wollastonite to rubber and plastic substrates, the compatibility between inorganic powder and organic materials is not good, leading to aggregation and affecting the performance of downstream rubber and plastic products. Therefore, before adding Wollastonite, its surface is usually modified with silane coupling agents. Modified and coated Wollastonite can better enhance the performance of rubber and plastic products.
In addition to modifiers, the modification and coating process also has a significant impact on the surface coating effect of Wollastonite. Throughout the modification process, it is essential to ensure thorough dispersion of Wollastonite and silane coupling agents to achieve a more uniform mixture. Currently, it appears that the atomization mixing process is more suitable for the surface coating of Wollastonite. TungKuLa T-MIX powder surface coating machine, employing the atomization process for modifiers, achieves a modification rate of over 99%, making it a relatively perfect Wollastonite modification process.
