Regeneration of silicon carbide cutting fluid

First: Introduction
Recently, the shortage of energy and pollution is much worse. The light industry is the leader of the safety industry. But the regeneration of silicon carbide cutting fluid is not widely used. The company invests a large amount of money into this field. The products are the result of the whole company’s efforts. After years of independent research and development of recycling waste mortar scientific research and development projects, the company has completed the will of the silicon wafer processing line cutting scrap mortar and suspension (ethylene glycol) by way of physics, which silicon micro powder and suspension can recycle. At the same time, the products make the recovery of silicon carbide powder and suspension with brand-new silicon carbide powder and cutting liquid with the performance of a silicon chip and satisfy the requirement of production, to replace the brand-new silicon micro powder and cutting fluid new materials. Company invests more than 8 million Yuan to complete the processing of more than 5,000 tons of thick liquid cutting scrap mortar regeneration production equipment.
