冷拔钢管第三代磷化剂(三磷剂)的使用探讨

APPLICATIONS OF THE THIRD GENERATION OF PHOSPHATIZING SOLVENT TO COLD-DRAWN STEEL TUBES

简介了第三代磷化剂(三磷剂)的成膜原理。通过使用,比较了三代磷化剂的工艺技术性能。实践证明,第三代磷化剂是目前使用性能最好的一种冷拔钢管磷化剂。

The filming principle of the third generation of phosphatizing solvent on steel tubes is described. The process performances of the three generations of phosphatizing solvents are compared in practice. It is proved that the third one is the best for cold-drawn steel tubes at present.
