同志們!我今天的發言可能不够完整,但是根据油漆車間設計同志們的要求,我准备談几个对油漆車間設計同志比較重要的問題。这些問題与金屬防蝕有关,同时也与作为保証金屬免于銹蝕的一种有效方法的油漆車間設計有关。金屬是現代化工業的基础。金属的需要量在逐年增加,其需要量業已达到惊人的程度。金属在使用过程中逐漸損坏,銹蝕是金屬構筑物和金属制品損坏的主要原因,銹蝕对国民經济是一个很大的威胁,根据金屬防蝕部門的統計,每年因銹蝕而損耗的金属占国家所用金屬总吨数的1～％,金属銹蝕損耗每年达几千万吨,因此金屬的防蝕对整个国家来說有很重要的意义。近代所采用的金屬防蝕方法有哪些呢?油漆是黑色金属主要的防
Comrades! My statement today may not be complete, but according to the requirements of the paint shop design comrades, I am ready to discuss several issues that are important to the design of the paint shop comrades. These problems are related to metal corrosion protection and are also related to the paint shop design as an effective method to ensure metal free from corrosion. Metal is the foundation of modern industry. The demand for metals has increased year by year, and its demand has reached an alarming level. Metals are gradually damaged during use. Corrosion is the main cause of damage to metal structures and metal products. Corrosion poses a great threat to the national economy. According to the statistics of metal corrosion protection departments, the annual loss of metal due to corrosion accounts for With 1 to 2% of the total metal tonnage used by the country, metal corrosion losses amount to several ten million tons per year. Therefore, the corrosion protection of metals is of great significance to the entire country. What are the metal anti-corrosion methods used in modern times? Paint is the main defense against black metal
