Ronggang brand plastic pipe manufacturing process?
1. Surface treatment Surface treatment can improve the adhesion of the coating film to the tube and the durability of the coating film.
2. Before the pre-heating spraying, the treated tube shall be heated in a baking furnace and the heating temperature is about 200 degrees. The surface of the heated tube melts the epoxy powder (or PE) coating sprayed onto the surface of the tube to produce a uniform coating film.
3. The common method for spraying pipeline spraying is the compressed air spraying method, which is to use the spray gun as a tool to spray the paint on the surface of the preheated tube by means of compressed air. The thickness of the coating is controlled by the amount of powder coating sprayed, the time of dusting, and the speed of the line (the speed of the gun or tube). Why is the coating thickness generally 150 ~ 300uM.
4, the surface coating is difficult to automatically apply to the artificial spray gun for additional coating.
5. Bake-curing The melt-coated tube is heated in a baking oven and melted and leveled to form a cross-linked curing.
6, cooling the baked tube out of air or air cooling.
7. Verification Inspection of plastic-coated pipes, including appearance, film thickness, corrosion resistance, wear resistance, density, hardness, bond strength, or adhesion.
8. Packing and Transportation Fit the pipe flange or port with effective sealing, and wrap the surface of the pipe with soft material such as glass fiber cloth (requiring plastic coating inside and outside), and take effective measures to avoid coating during loading and transportation. The layer is damaged.
