腐蚀问题给人类带来了巨大的经济损失和社会危害,为了防止钢铁制件的腐蚀,延长设备、材料的使用寿命,必须先将钢铁制件的铁锈清除干净,并进行表面防腐处理. 对于钢铁制件最常用的除锈方法是经过盐酸或硫酸酸洗除锈.酸洗的主要问题是酸雾严重,腐蚀设备,污染环境,并影响操作者身体健康.除锈后如不及时进行后处理,又会重新锈蚀.虽然除锈后可以立即进行磷化处理,防止锈蚀,但又增加操作工序.
Corrosion problems have brought enormous economic losses and social harm to human beings. In order to prevent the corrosion of steel parts and extend the service life of equipment and materials, the rust of steel parts must be cleaned up first and the surface is treated with anti-corrosion. The most common method of rust removal is hydrochloric acid or sulfuric acid pickling rust. The main problem of acid pickling is the severe acid mist which corrodes the equipment and pollute the environment and affects the operator’s health. , Will re-rust.Although derusting immediately after phosphating to prevent corrosion, but also increase the operating procedures.
