宜兴市腐植酸厂是70年代后期建设的综合化工厂。该厂位于江南鱼米之乡的宜兴市,是“陶器的天地、茶叶的绿洲、溶洞的世界”。10多年来,产品有染料、助剂、中间体等。其中腐植酸产品有硫化黑棕和铬腐植酸等。一、铬腐植酸9233:铬腐植酸是一种非离子型的有机化学处理剂,采用高纯度的腐植酸和高价铬酸盐络合及螯合而成。生产工艺是在碱性介质中,腐植酸通过液一固两相加热,混合研磨被还原成有机物,再经过置换、氧化、螯合作用而使其断裂,使腐植酸活性基团增多,化学活性增强,水溶性增大,提高了处理剂的效力。产品外形呈棕褐色粉末,水溶液为黑棕
Yixing humic acid plant is the construction of a comprehensive chemical plant in the late 70s. The plant is located in Yixing City, where fish and rice from Jiangnan are located. It is the world of pottery, the oasis of tea and the world of karst caves. More than 10 years, the products are dyes, additives, intermediates and so on. Among them humic acid products are sulfur black brown and chromium humic acid. First, the chromium humic acid 9233: Chromium humic acid is a non-ionic organic chemical treatment agent, the use of high-purity humic acid and high-priced chromate complexation and chelation. The production process is that in an alkaline medium, the humic acid is heated to solid-liquid and solid-phase by a liquid and mixed and ground to be reduced to an organic substance, and then broken, oxidized and chelated to make the humic acid active groups increase and the chemical activity Enhanced water solubility increases, increasing the effectiveness of the treatment agent. Product appearance was brown powder, water solution is black-brown
