有许多另部件是由铆接、焊接、静配合或螺蚊配合连接而成的,金属的锈蚀常常从这些结合缝隙开始并向周围漫延,造成另件大批返修等等.对此我们进行了各种试验.试验表明,蒸锅蒸除残碱法,手工蒸汽吹除法效果均不大好;酸中和法,皂化法由于成本高,工艺复杂也不宜采用;而烘法除碱效果好,工艺简单、成本低,无公害,用以除去连接件在表面处理时残存在缝隙中的残碱较为适宜. There are many other parts are connected by riveting, welding, static fit or spiral mosquito mating, metal corrosion often starts from these joint gap and spread to the surrounding, causing a large number of other pieces of repair, etc. For this we have carried out a variety of The results showed that the effect of the steam distillation method was not very good. The acid neutralization method and the saponification method were not suitable because of the high cost and complicated process. Low cost, pollution-free, in order to remove the surface of the connector remains in the cracks in the residual alkali is more appropriate.
