Active silicon powder product series: China ultra-white silicon powder, silicon powder for insulating casting of high-voltage electrical devices, silicon powder for casting high-voltage electrical appliances, and copper-clad laminate silicon powder. Features of our company's active silicon powder: It is made by compound activation using imported organic coupling agent as the main raw material. The activation rate is high, it is easy to disperse, and the addition amount is large.

70 soil 0.5°C viscosity test:

Material A mixture:

2500A1: 138g + silica powder: 162g, use an electric mixer to quickly stir for 8-10 minutes, until no particles can be seen. Then place it at a constant temperature of 70±0.5°C to test the viscosity (the test uses the No. 2 rotor, 30 revolutions

test)

B material mixture:

2500B1: 114g + silica powder: 186g, use an electric mixer to quickly stir for 8-10 minutes, until no particles can be seen. Then place it at a constant temperature of 70±0.5°C to test the viscosity (the test uses a No. 2 rotor, 6 or 12 revolutions test). After measuring the viscosity, pour the mixture of materials A and B into a 100mL volume (approximately 100mL), and place it in an 80°CC oven. After 24 hours, take out the measuring cylinder to test the sedimentation height. How to judge the settlement height: Use a glass rod or thermometer to put it in a measuring cylinder, and let the glass rod slowly slide down. After 1 minute, the bottom of the glass rod reaches the height of the settlement. Product usage characteristics: the advantages of simple ratio and good operating performance; the shrinkage of the cured product is small, the size of the molded part is stable, the electrical performance is superior, and it has good impact resistance and anti-spreading performance. It is mainly used in electronic and electrical products Insulation casting.

Active silicon powder is based on ordinary crystalline silicon powder and uses silane composite materials to modify the surface of silicon powder particles through a unique process, thereby changing the surface lipophilic properties of silicon powder, which is effective

It can improve the adhesion of resin and silicon powder and the hydrophobicity of the interface, thereby increasing the mechanical strength, elastic modulus, thermal aging performance, weather resistance of the cured product, and more importantly, it can greatly improve the partial free discharge of high-voltage electromechanical products. The occurrence of the phenomenon. The reactive silicon powder reacts with the resin and curing agent to cross-link, and will not promote and retard the resin and curing agent system

The progress of the curing reaction does not affect the casting process. Active silicon powder is widely used in industries such as the casting of medium and high voltage electrical appliances and the packaging of electronic materials.
