Internal epoxy white ceramic anti-corrosion steel pipe manufacturer

Hebei Tianze Pipe Industry [Manager Bi] Co., Ltd. specializes in the production of epoxy white ceramic anti-corrosion, white ceramic anti-corrosion steel pipes, non-toxic anti-corrosion steel pipes, non-toxic anti-corrosion steel pipes for water supply pipelines, anti-corrosion steel pipes for drinking water, anti-corrosion steel pipes for tap water projects, non-toxic Anti-corrosion steel pipes for drinking water and anti-corrosion spiral steel pipes are welcome to discuss. Overall, the anti-corrosion coating used in anti-corrosion steel pipes still plays a very important role. In the future, anti-corrosion steel pipes will definitely have more practical performance. The epoxy coating used to make Cangzhou anti-corrosion steel pipes has good adhesion to metal, concrete, wood, glass, etc. It is resistant to alkali, oil and water, and has excellent electrical insulation properties. However, it has poor aging resistance. Epoxy anti-corrosion spiral steel pipe Paint is usually composed of two components: epoxy resin and curing agent. The properties of the curing agent also affect the performance of the paint film. Commonly used curing agents are: ① Fatty amines and their modifications. The characteristic is that they can be cured at room temperature without modification. Sexual aliphatic amines are more toxic. ② Aromatic amines and their modifications are characterized by slow reaction, often require heating and curing, and have weak toxicity. ③ Polyamide resin. Characterized by good weather resistance, low toxicity, and good elasticity. The corrosion resistance is slightly worse. ④ Phenolic resin, urea-formaldehyde resin and other synthetic resins. These resins and epoxy resins are baked at high temperature and then cross-linked to form a film. The paint film has outstanding corrosion resistance, and has good mechanical properties and Decorative.

The three-layer process of coating polyethylene with epoxy powder and winding or coating with adhesive is a commonly used steel pipeline anti-corrosion process at home and abroad. It is also the current domestic West-East Gas Transmission and Oilfield Oil Transmission. , gas, pipeline anti-corrosion technology used in urban gas and water supply.
Edit this paragraph Anti-corrosion process of epoxy powder
Principles of anti-corrosion process The quality of pre-treatment has a great influence on the performance of the coating. In the actual coating process, there are many examples of failure to achieve the expected anti-corrosion effect due to poor pre-treatment. In particular, many anti-corrosion coatings with excellent performance can form normal coatings and achieve the expected anti-corrosion protection only by strictly following their respective requirements. The steel base material must be rust removed, degreased, and phosphated. The thickness of the anti-corrosion coating must exceed its critical thickness to exert a protective effect, generally ranging from mm to mm. If the primer is left for too long before the topcoat is applied, it will be difficult to adhere and affect the overall protective effect. Epoxy powder dipping new process Epoxy powder has always been coated using electrostatic spraying process. Because the epoxy powder dipping process is plagued by adhesion problems, epoxy powder dipping has never been widely used. In recent years, with the successful development of Sanye's special phosphating solution for epoxy powder dipping, the adhesion problem of the epoxy powder dipping process has been overcome for the first time, and the emerging process of epoxy powder dipping has begun to be promoted
