金属喷涂法使用范围甚广,其中喷涂防锈是应用最广泛的工艺之一。其方法是:先把工件除锈打毛(本工程采用喷石英砂);然后用喷涂喷枪把锌(铝)丝或粉熔化喷成雾状,吹到准备好的工件上,形成锌(铝)喷层,封闭工件,防止腐蚀。据国内外资料和实验证明;当锌(铝)喷层在0.05毫米时即已开始对大气具有防锈作用;当喷层在0.1～0.15毫米时已具有极优良的防锈性能,且比热镀锌具有更好的所谓“远程保
Metal spray coating uses a wide range, including spraying rust is one of the most widely used process. The method comprises the following steps: firstly, rusting and shaving the workpiece (the project adopts quartz sand sprayed); then the spray gun is used to melt the zinc (aluminum) wire or powder into a mist and blow it onto the prepared workpiece to form a zinc Spray layer, the closure of the workpiece, to prevent corrosion. According to domestic and foreign data and experiments show that when the zinc (aluminum) spray layer at 0.05 mm when the atmosphere has begun to have a rust-proof effect; when the spray layer at 0.1 ~ 0.15 mm has a very good anti-rust properties, and specific heat Galvanized has better so-called "Remote Paul
