The production principle, process flow, organization and operation model of sodium bisulphate system are reviewed. 对亚硫酸钠系统的生产原理、工艺流程、生产组织及运行方式进行了概述。
Of abundant blocking agents, the bisulphate salt has special properties such as low unblocking temperature, low price and almost no pollution. 在众多异氰酸酯封闭剂中亚硫酸盐类的解封闭温度最低,价廉易得,基本上不存在污染问题。
