在人造纤维生产中,使用大量有腐蚀性的化学原料。腐蚀问题的解决,有非常重要的意义。有酸雾或其他化学品气体接触的厂房钢架,可用铝或锌喷涂(约0.003～0.004时厚)。在一般情况下,油漆也可应用。但在比较严重的腐蚀环境中,金属喷涂价格虽贵,却较经济有效,尤其是在钢架制造中喷涂金属更好。稀硫酸聍槽及纺絲机上的槽都可用铅板衬里。排除废气的管道可用铝板制造。纯度99.8%的铝板比99%的耐腐蚀性好。即使用99.8%的铝,在焊接处还是容易腐蚀。用电弧焊接,可以改善腐蚀情况。醋酸纤维工厂使用醋酸及醋酐较多,可用含18%铬、10%镍及2.5%钼的不锈钢板及管道。不锈钢絲篩
In man-made fiber production, the use of a large number of corrosive chemical raw materials. Corrosion problems, there is a very important significance. Steel mills with acid mist or other chemical gases may be sprayed with aluminum or zinc (about 0.003 to 0.004 hours thick). In general, paint can also be applied. However, in the more serious corrosive environment, the price of metal spraying is more expensive, but it is more economical and effective, especially spraying the metal in the manufacture of steel frame. Dilute sulfuric acid tank and the slot on the spinning machine can be used lead plate lining. Exhaust pipe can be made of aluminum. 99.8% purity aluminum than 99% of the corrosion resistance. Even with 99.8% aluminum, it is easy to corrode at the weld. With arc welding, can improve the corrosion situation. Acetic acid plant acetic anhydride and acetic anhydride used more available with 18% chromium, 10% nickel and 2.5% molybdenum stainless steel plate and pipe. Stainless steel wire screen
