船舱内壁的除锈,尤其是小型船舱的除锈,由于舱容小、结构复杂,使用诸如喷砂、抛丸等方法都有困难。即使解决了除锈操作问题,但是照明、通风和清理也极不便。一九六七年在建造油罐船时,开始采用了化学除锈工艺。十几年来,化学除锈在我厂已作为常规工艺使用,尤其是管子及一些舾装件,基本上都采用这一工艺除锈,在提高生产效率,降低劳动强度各方面都取得了良好的效果。
Rust removal from the inner walls of the tanks, especially for small tanks, has been difficult due to its small tank capacity and complex structure, using methods such as blasting and shot blasting. Even if the problem of rust removal operation is solved, lighting, ventilation and cleaning are also very inconvenient. In 1967 when building a tanker, chemical descaling began to be used. More than 10 years, chemical rust in our plant has been used as a conventional process, especially pipe and some fittings, basically using this process derusting, to improve production efficiency, reduce labor intensity in all aspects have achieved good effect.
