1 引言 随着我国金属加工的迅速发展,金属的表面处理,尤其是漆前处理——磷化工艺的应用也日趋广泛,随之对该工艺的要求愈来愈高,目前较多数磷化液使用温度一般在40～90℃,结晶粗大,膜层较厚,磷化时间长,沉渣多,成本高,不能满足高质量低成本的要求,本工作研制一种常温、少渣快速磷化液,该磷化液适用于汽车、自行车、农机、家电、电冰箱和洗衣机等各种黑色金属制品表面的漆前处理,处理后的磷化膜致密,结合力强,耐盐水性好,质量可靠。
1 Introduction With the rapid development of metal processing in our country, metal surface treatment, especially the pre-treatment - the application of phosphating process is also increasingly widespread, followed by the higher and higher the requirements of the process, the current number of phosphating solution The use of temperature is generally 40 ~ 90 ℃, coarse crystal, thick film, phosphating a long time, more sediment, high cost, can not meet the requirements of high quality and low cost, this work developed a room temperature, less slag rapid phosphating solution The phosphating solution is suitable for paint pre-treatment on the surfaces of various ferrous metal products such as automobiles, bicycles, agricultural machines, household appliances, refrigerators and washing machines. The treated phosphating film is dense, strong in binding, good in salt water resistance and reliable in quality .
