在工业生产中不断产生和散放大量的工业气体,不但污染环境,而且严重地腐蚀生产设备和建筑钢结构,缩短结构物使用年限,威胁生产安全,给国家造成巨大的经济损失。因此加强钢结构的防腐是一项十分重要的工作。建筑钢结构在其建造和使用过程中,经常受到高温、湿热、大气、雨水、姻尘、化学介质等因素的交替作用,在腐蚀过程中产生复杂的矛盾运动,我们必须深入地、精确地研究这些矛盾运动,针对使用环境条件、基层表面处理,涂料配套性、涂层厚度等问题,找出其特殊形态和普遍规律,从而为钢结构的防腐问题提供理论基础和设防手段。根据几年来现场钢结构防腐涂料观察,并结合现有文献的查对分析,已经掌握了不少可贵的资料。证明只要加强钢结构的表面处理、掌握底漆与面漆的配套性和漆膜厚度,并根据腐蚀性介质选择适宜的涂料品种,就可以使涂料在钢结构表面具有较强的附着力和较强的防锈能力,达到预期防腐的目的。 The continuous production and dispersion of industrial gases in industrial production not only pollute the environment, but also seriously corrode production equipment and construction steel structures, shorten the service life of structures, threaten production safety, and cause huge economic losses to the country. Therefore, strengthening the corrosion of steel structures is a very important task. During the construction and use of steel structures, building steel structures are often subjected to alternating effects of high temperature, damp heat, atmosphere, rainwater, dust, chemical agents, etc., which produce complex and contradictory movements in the course of corrosion. We must study in-depth and accurately. These contradictory movements are aimed at the use of environmental conditions, primary surface treatment, coating compatibility, coating thickness, etc., to find out their special forms and general rules, so as to provide a theoretical basis and fortification means for the corrosion of steel structures. According to the observation of the steel structure anti-corrosion coating on site over the past few years, combined with the investigation and analysis of the existing literature, many valuable materials have been mastered. It is proved that as long as the surface treatment of steel structures is strengthened, the compatibility of the primer and the top coat and the thickness of the paint film are grasped, and a suitable paint type is selected according to the corrosive medium, the paint can have a strong adhesion on the surface of the steel structure. Strong anti-rust ability, to achieve the desired anti-corrosion purposes.
