一、前 言 电泳制壳的优点是:简化制壳工序,降低成本,改善劳动条件。国内有些工厂于78～79年作过一些试验,后因熔模导电问题解决不了而中止。我院于81年正式开始试验,目前已较成功地解决了低电阻的导电薄膜,在4～5分钟内电泳结出有足够强度和厚度的壳型。浇注出各种牌号钢铸件一百多件。 所谓电泳,就是在悬浊液(或乳浊液)中的带电微粒,在外电场的作用下,向所带
First, the foreword The advantages of electrophoresis shell is: simplify the shell process, reduce costs, improve working conditions. Some domestic factories in the 78 to 79 years made some tests, after the melt conductivity problems can not be resolved and suspended. Our hospital officially started the experiment in 81 years, and has successfully solved the low resistance conductive film in 4 ~ 5 minutes electrophoresis to produce a shell with sufficient strength and thickness. Casting a variety of grades of steel castings more than 100 pieces. The so-called electrophoresis, that is, in the suspension (or emulsion) in the charged particles, the role of the external electric field to bring
