Application of silicon carbide composite materials in intumescent fire retardant coatings Intumescent fire retardant coatings have obvious effects in blocking the rapid impact of substrates. The type of intumescent fire retardant coating detergent and the composite material content have an impact on the fire retardant performance of the fire retardant coating. The results show that

China’s silicon carbide production process China’s silicon carbide smelting production process, technical equipment and energy consumption per ton have reached the world’s leading level. The quality level of black and green silicon carbide blocks is also world-class. The gap between China’s silicon carbide and the world’s advanced level is mainly including four aspects: First, there

Can silicon carbide be exported? Yes ,it can be exported. Silicon carbide is a common commodity. When exporting, you only need to provide an export certificate. The main component of silicon carbide is SiC, and the colors are green and black. The same model of green silicon carbide is more expensive. Both green and black

Which one is harder, green silicon carbide or black silicon carbide? Silicon carbide has two commonly used basic abrasive products: black silicon carbide and green silicon carbide. 1. Black silicon carbide contains about 98.5% SiC, and its toughness is higher than that of green silicon carbide. It is mostly used to process materials with low

Is silicon carbide toxic? Silicon carbide itself is non-toxic and harmless, but excessive inhalation of silicon carbide powder can cause pneumoconiosis. Secondly, no damage has been found from physical contact, and regular contact with silicon carbide powder may cause pneumoconiosis. Therefore, workers who have been engaged in silicon carbide production for a long time need
