The anticorrosive method of melting epoxy powder:
Mainly: static spraying method, thermal spraying method, pumping method, fluidized bed method, rolling coating method, etc. The coating in the pipeline generally uses the friction static spraying method, the suction method, or the thermal spraying method; these several spray methods have a common feature, that is, the workpiece needs to be preheated to a certain temperature before spraying. The residual heat should continue to flow the coating film, and further flow the surface of the entire steel pipe, especially on the depression on the surface of the steel pipe, and on both sides of the weld. The pores are solidified within the specified time, and finally the solidation process is terminated with water cooling.
