在钢丝热镀锌生产工艺中,需将钢丝经过酸洗、碱洗、涂上助镀剂再到锌锅进行热镀。酸洗过程中,我厂采用HCl含最为31%的工业盐酸配制成180~200克/升浓度的溶液为酸洗液。由于盐酸易于挥发,在常温下,盐酸中的HCl气体也易跑入空气中,与水蒸气相遇,形成白雾。空气中HCl含量为0.04%就会影响呼吸作用,对人体健康造成危害,HCl气体还会严重腐蚀厂房、设备,降低厂房、设备的使用寿命。在同行业中,为了消除HCl气体的危
In the galvanized steel wire production process, the steel wire needs to be pickled, washed with alkali, coated with a flux and then galvanized to a zinc pot. Pickling process, I plant using HCl containing the most 31% industrial hydrochloric acid formulated into a solution of 180 to 200 g / L concentration of pickling solution. As hydrochloric acid is easy to volatilize, at room temperature, HCl gas in hydrochloric acid is also easy to run into the air, and water vapor meet to form a white fog. HCl content of 0.04% in the air will affect the respiration, harm to human health, HCl gas will seriously corrode the plant, equipment, reduce plant and equipment life. In the industry, in order to eliminate the danger of HCl gas
