水表行业在表壳涂装上一般采用硝基皱纹漆涂装表面,在表壳内壁一般涂装铁红底漆和大红面漆。硝基皱纹漆涂装性差,而且易因水和酸碱的浸渍腐蚀而锈蚀;在喷涂漆时,不仅漆尘和有毒溶剂严重污染环境,而且漆的浪费大,生产效率低,生产成本高。鉴于以上原因,急待选用优质涂料和先进喷涂工艺来取代落后的硝基漆及其喷涂工艺。我厂从一九八一年至一九八三年研制成功“粉末静电喷涂联动线”,经省市主管部 Water meter industry in the case of paint on the general use of nitro wrinkle paint coating surface, the case wall generally coated iron red primer and red finish. Nitro wrinkle paint coating is poor, but also easy due to water and acid-base immersion corrosion and rust; spray paint, not only paint dust and toxic solvents seriously pollute the environment, and paint waste, low productivity, high production costs. In view of the above reasons, the urgent need to use high-quality paint and advanced spray technology to replace the lacquer and lacquer spraying process. I plant from 1981 to 1983 successfully developed “powder electrostatic spraying linkage line”, by the provincial Department in charge
