我厂在批林批孔运动的深入开展中,不断改进操作条件,最近三车间一组同志在二车间同志的帮助下,又初步解决了两项安全技术问题。 一是生产硫氰化钾和硫氰化钠时,过去投固体氰化钾和氰化钠,粉尘很大。现在改用不锈钢罐溶解,凭温度控制,就可以防止氰化钾(钠)的粉尘,改为减压合成,? In our bidding and approval of the hole campaign in-depth development, the continuous improvement of operating conditions, a group of three workshops recently comrades in the workshop with the help of two comrades, but also initially solved the two safety issues. First, the production of potassium thiocyanate and sodium thiocyanate, the past cast solid potassium cyanide and sodium cyanide, dust large. Now use stainless steel tank dissolved, with temperature control, you can prevent the potassium cyanide (sodium) of the dust, to decompression synthesis?
