葫芦岛锌厂在火法冶炼、湿法冶炼及化工生产中,设备腐蚀相应严重,每年大、中修所需钢材为1000吨左右,设备检修费逐年增加。过去在防腐蚀方面主要采用铅、铜合金、不锈钢及瓷砖等,六十年代以后逐步用一些 PVC 塑料及玻璃钢,1974年开始试用钛材。八年来在小型挂片试验取得初步成效的基础上,逐步推广使用,现已在该厂普遍使用。 Huludao Zinc Plant in pyrometallurgy, wet smelting and chemical production, the corresponding serious corrosion of equipment, annual large, medium repair required for the 1000 tons of steel, equipment maintenance costs increased year by year. In the past, anti-corrosion mainly used lead, copper alloy, stainless steel and ceramic tile. After the 1960s, some PVC plastic and glass fiber reinforced plastic were used step by step. Since 1974, trial titanium material has been used. Eight years in the small coupons trial achieved initial results, based on the gradual promotion of use, is now widely used in the plant.
