摘要
随着国家对基础设施投入的增加,高速公路护栏、电力铁塔及空冷设备、工业流体输送管、屋顶瓦楞彩板、室外钢结构等需求量逐年增加,这些安装在室外的不允许经常拆卸的大型设备及部件要求具有耐不少于30年的防腐蚀能力,实现以上的有效方法是采用热浸镀锌。对热浸镀锌理论研究及工艺控制程度反应了一个国家在该领域技术水平的高低。
With the most investment to capital construction such as highway guardrails, electrical towers, air cooled equipments, liquid feeding pipes, housetop color steel plates and other structures required more and more by ever year. All of them must be used more than 30 years. To achieve this purpose, the best and valid way to preventing them from corroding is to galvanizing. How much degree of study galvanizing technology shows the technical level in this field for a country. Here discuss the galvanizing knowledge for reference.
