在化工、冶金、机械、轻工等各工业企业的建筑物和构筑物的一切金属和非金属部件经常受到化学、电化学、物理溶解以及拌随生物和机械等的作用而引起严重腐蚀,造成厂房建筑和地下管网的损坏和塌陷,原材料和产品的流失和污染,降低设备和管网的使用效率,引起环境污染,其影响范围之广,经济损失之巨,极为严重。防腐工作应以预防为主,调查和研究工程所处的环境和介质状况,例如地下工程则需了解水质、土质、污水排放、水中微细粒子的影响等等,并在此基础上尽可能排除产生腐蚀的根源,隔离腐蚀环境,消除主要腐蚀因素,以控制腐蚀的范围。因此各有关专业必须密切配合,采取有效的防腐蚀措施。在工艺设计上要进行必要的改革,严密工艺设计;在选材上应尽可能掌握影响腐蚀的变化因素,选用耐蚀性较强的材料;在维修和管理上应根据腐蚀介质,影响程度,轻重缓急,分类设防,区别对待。同时坚持必要的规章制度和操作规程,做到文明生产,才能使防腐蚀措施,取得理想的效果。
All metal and non-metal parts of buildings and structures in chemical, metallurgy, machinery, light industry and other industrial enterprises are often subjected to severe corrosion due to chemical, electrochemical, physical dissolution and mixing with biological and mechanical effects, resulting in a plant The destruction and collapse of buildings and underground pipe networks, the loss and pollution of raw materials and products, the reduction of the use efficiency of equipment and pipe networks, and the resulting environmental pollution have a wide range of impacts. The economic losses are extremely serious. Anti-corrosion work should be based on prevention, investigation and study of the environment and medium conditions in which the project is located. For example, underground projects need to understand the effects of water quality, soil quality, sewage discharge, and fine particles in water, and should be excluded as much as possible. The root cause of corrosion is to isolate the corrosive environment and eliminate the main corrosion factors to control the extent of corrosion. Therefore, all relevant majors must cooperate closely and adopt effective anti-corrosion measures. In the process design must carry on the necessary reforms, strict process design; in the selection of materials should be as much as possible to grasp the factors that affect the change of corrosion, the use of materials with strong corrosion resistance; in the maintenance and management should be based on the corrosive medium, the degree of influence, the priority , Classified fortification, treated differently. At the same time adhere to the necessary rules and regulations and operational procedures, so that civilized production, in order to make anti-corrosion measures to achieve the desired results.
