三五六厂对某产品工艺采用去油→磷酸酸洗→磷化→喷漆工艺,减轻了原喷砂工艺的繁重负担,大大提高了生产率.此工艺优点是:节省化学材料、蒸气,提高工效,降低成本对人体无害,保护了环境卫生,经多次试验投产,保证了产品质量.工艺配方:磷酸[H_3PO_4] 150～180g/l醋酸铅0.04～0.06g/l若丁(二邻甲苯基硫脲) 0.02～0.04g/l石油磺酸20～30g/l
356 plants on the use of a product of the process of degreasing → phosphating → phosphating → painting process, reducing the heavy burden of the original sand blasting process, greatly improving productivity. This process has the advantages of: saving chemicals, steam, and improve work efficiency , Reduce the cost of harmless to the human body, protect the environmental health, after many trials put into operation, to ensure product quality. Process formula: Phosphoric acid [H_3PO_4] 150 ~ 180g / l Lead acetate 0.04 ~ 0.06g / Thiourea) 0.02 to 0.04 g / l Petroleum sulfonic acid 20 to 30 g / l
