Pretreatment mainly involves soaking tank, spray tank, standby tank, circulation system, etc. our professional technicians provide the best design scheme, manufacturing, installation and after-sales one-stop service after inspecting the customer's site, to ensure the cleanness of metal surface and the quality of pretreatment conversion film, so as to provide an excellent precondition for the overall coating quality.

This product is high concentration room temperature zinc iron series phosphating agent, the film layer crystallization is meticulous, appearance appears blue or color red phosphating film.It can be compatible with electrophoresis, plastic spraying and baking process, and has the advantages of good adhesion.This phosphating agent is used at room temperature, simple to operate, low cost, less sediment, etc., is a new type of phosphating agent, it is suitable for automobile, motorcycle tricycle, agricultural vehicle industry and other steel parts before painting corrosion treatment.

1. improve the impurities brought in by the previous step of pretreatment, especially the substances brought in by the parts with complex shapes.To improve the bad condition of workpiece caused by degreasing groove.It can also improve the bad effect of phosphorization caused by the precipitation of carbon from the workpiece surface due to pickling. 2. surface adjustment can make the film thickness of phosphating film in a stable state. 3. it can reduce the amount of residue in the phosphating solution. 4. reduce the consumption of phosphating solution. 5. reduce the consumption of accelerators. 6. reduce the phosphating process temperature. 7. to make the phosphating film oriented crystallization in a favorable direction.

1. Free from harmful hexavalent chromium and other harmful substances, it is a green product. 2. Suitable for all kinds of metal and after electroplating treatment, the anti-discoloration effect is good. 3, the formation of anti-discoloration film with hate water and welding function, drying without water stains. 4, after anti-discoloration treatment, the surface is smooth, no hand print. 5. Only produce extremely thin protective film on the surface of the workpiece, which can prevent discoloration economically.
