Trichloroisocyanuric acid (TCCA), which is dominated by the consumption of disinfectants, faced many problems and difficulties such as overcapacity and export obstruction. The TCCA operating rate showed a declining trend year by year. Customs statistics show that since the beginning of this year, the TCCA market has sold at a price of 8,000 to 15,000 yuan per ton, and the average operating rate of the industry is 61%. Compared with the relatively mature TCCA industry, the domestic consumer...
Silicone oil or silicone fluid chemicals refers to linear polysiloxane products that remain liquid at room temperature. It is divided into two types of silicone oil: methyl silicone oil and modified silicone oil. The most commonly used silicone oil is methyl silicone oil, also known as ordinary silicone based oil, its organic groups are all methyl, and the silicone oil that uses other organic groups to replace some methyl groups is called modified silicone oil. Silicone lubricating oil would be...
The cyanide-containing tailings slurry of the cyanide carbon pulp gold extraction plant has a high water content, high cyanide content, and difficult solid-liquid separation.
