一种可替代进口产品的磷化液DSM997的研制

Development of DSM997 a Phosphate Solution Instead of Import Products

针对进口磷化液Fosbond78价格高、进口手续繁杂等问题,研制了一种单组分、快速低渣、工艺简单、成本低廉的中温磷化液———DSM997,并对其配制、应用及影响磷化质量的主要因素进行了分析和探讨。经大批量生产应用表明,该磷化液及磷化膜性能优良,完全可以替代进口产品。

In view of high price and complicated formalities of imported Fosbond78 phosphatizing solution,a moderate temperature phosphatizing solution,DSM997,with its advantages of a single component,fast processing and less slag,simple process and low cost has been developed.This paper presents the analysis and discussion of make-up and application of the phosphatizing solution as well as the factors affecting the phosphatizing quality. It is shown by high volume production that the phosphatizing solution and the phosphatizing film have excellent performances and can be substituted for the import products completely.
