The rinsing and commissioning in silicate pretreatment line with a capacity of 150 thousand were introduced.From preparation work of the early stage,rinsing and commissioning process and matters needing attention were discussed.Compared with the ordinary phosphating line,the requirement of the cleanliness of the silicate pretreatment line is higher,so the inspection and acceptance of the rinsing result is more important,and the usage amount of pure water is also larger.More attention should be paid to the preparation ability of the pure water system and the sewage treatment ability.
