某制革厂引进成套生产设备,生产人造革。其工艺流程是:配料-搅拌-涂料-水浸-烘干-卷取。主要原料为二甲基甲酰胺(约占70%),其次有少量树脂、色料等(约占30%)。主产时将原料放入铁桶里,搅拌后送入涂料桶,由涂料桶机械加料,然后手工将其均匀涂布在聚氨酯彩纸上,经过35～50℃水浸后烘干即为成品。毒物主要由配料和涂料工序挥发逸散到整个车间。1991年6月17～18日试生产时,每天连续作业12小时,由于车间通风差,逸散在车
A tannery to introduce complete sets of production equipment, the production of artificial leather. The process is: ingredients - mixing - paint - flooding - drying - coiling. The main raw materials for dimethyl formamide (about 70%), followed by a small amount of resin, color, etc. (about 30%). When the main production, the raw materials are put in the iron drum, and then the materials are poured into the paint bucket after being stirred. The paint is mechanically fed by the paint bucket, and then evenly coated on the polyurethane colored paper by hand. After the water is dried at 35 to 50 DEG C, the finished product is finished. Poison mainly by the ingredients and paint processes evaporate to the entire workshop. 1991 June 17 ~ 18 trial production, continuous operation for 12 hours a day, due to poor ventilation workshop, escape in the car
