为了提高金属材料的机械性能,国内一般采用盐浴淬火。由于热处理过程中残盐清洗不干净,在加工过程中将残盐带到冷却液中,不但腐蚀加工的零件而且还会腐蚀机床,要除净这种残盐,我国多采用水煮,部份用表面活性剂(如6503、664、321金属清洗剂)清洗。这些清洗材料对清洗油污有效,但除盐不彻底(尤其是高温残盐),渗透性能较差,不能满足
In order to improve the mechanical properties of metal materials, the domestic salt bath quenching. As the heat treatment of residual salt cleaning is not clean, the residual salt in the process of cooling to the coolant, not only corrode the processing of parts but also corrosion of the machine, in addition to net the residual salt, our country use more boiled, part With surfactants (such as 6503,664,321 metal cleaning agent) cleaning. These cleaning materials are effective for cleaning oil, but the desalting is not complete (especially high-temperature residual salt), the permeability is poor and can not be met
