介绍了一种聚丙烯酰胺涂层技术。通过室内评定、工业化涂层应用试验和现场配注应用试验证明 ,合成的聚丙烯酰胺粉末涂层剂 TC-0 6具有很好的降低聚丙烯酰胺细粉扬尘效果。涂层后的聚丙烯酰胺抗剪切能力、耐盐能力和热稳定性均有一定程度的提高。涂层操作简便易行 ,利用聚丙烯酰胺现有工艺设备就可进行生产。采用本涂层技术可在聚丙烯酰胺正常生产中和处理库存细粉中创显著的经济效益和社会效益 ,同时 ,大大改善了生产装置和现场配制的粉尘问题 ,给生产和应用操作人员创造了更好的工作环境。
A polyacrylamide coating technology is introduced. Through indoor evaluation, industrialized coating application test and on-site pouring application test, it is proved that the synthesized polyacrylamide powder coating agent TC-0 6 has a good effect of reducing the dusting effect of the polyacrylamide fine powder. Coating after the anti-shear capacity of polyacrylamide, salt tolerance and thermal stability are to some extent improved. Coating easy to operate, the use of polyacrylamide existing process equipment can be produced. Adopting the coating technology can bring remarkable economic and social benefits in the normal production of polyacrylamide and the processing of the inventory of fine powder, meanwhile, the problem of dust on the production device and on-site preparation has been greatly improved, and the production and application operators have been created A better working environment.
