沈阳冶炼厂锌冶炼车间从五十年代初投产以来,在设备防腐技术方面不断得到改进。五十年代一般采用铅材,火漆,橡胶作为锌电解中主要防腐材质。六十年代开始采用玻璃钢,聚氯乙烯及不锈钢。生产实践表明,上述几种防腐材质,一般是比重大,抗腐性能不够理想,并且价格比较昂贵。因此,车间停产检修 Shenyang smelter zinc smelting plant since the early 1950s put into operation, equipment, anti-corrosion technology continues to be improved. The fifties commonly used lead, paint, rubber as the main anti-corrosion materials in zinc electrolysis. Sixties began using glass, PVC and stainless steel. Production practice shows that the above-mentioned several kinds of anti-corrosion materials, generally large proportion, anti-corrosion performance is not ideal, and the price is more expensive. Therefore, the workshop discontinued maintenance
