1. Color coated galvanized steel plate The base material of is steel with light weight and high force.
2. After continuous hot dip treatment, a galvanized alloy layer is formed on both sides of the steel plate. Field tests in different environments for 20 years have confirmed that under the same environment, galvanized steel plate is more than four times longer than galvanized steel.
3. Apply a layer of chemical film on galvanized steel to increase its anti-corrosion function.
4. Coat the chemical film with more corrosion resistant epoxy Base resin Primer 。
5. The surface layer is coated with colored coating special strong chemical polyester with good weather resistance to ensure that the galvanized steel plate can maintain its original color and luster after years of use
Zinc rich scaling - zinc rich phosphating generates a phosphate protective film on the surface of the substrate that is difficult to melt in water, and the protective film itself can isolate air and Pipe The contact of the substrate can prevent corrosion and rust. In addition, the scaling solution can corrode tiny holes on the hot-dip galvanized layer of pipes to enhance the adhesion and protection between the coating film and the steel substrate, and improve the coating quality of the steel substrate; After each pretreatment process, the workpiece enters the plastic spraying workshop for plastic spraying processing; The zinc epoxy powder coating of agricultural production system has good corrosion resistance, good moisture resistance and chemical resistance, and has strong adhesion with steel substrate. The polyester color powder coating not only has good corrosion resistance, especially has high stability in preventing direct light, but also has good long-term dirt resistance and surface self-cleaning performance. The two spraying layers are closely combined with each other and pushed forward layer by layer, playing a complementary, enhanced and enlarged anti-corruption effect. It is a whole agricultural production system and plays a special and irreplaceable role in forming a "long-term coating". Degreasing - removing grease and impurities on pipes; Water washing - clean with pure water twice to remove degreasing agent; Table adjustment - neutralize the residual degreasing agent on the surface of the pipe, and the measured PH value is 7; Water washing - wash off the surface liquid.
