Introduce advanced welding equipment, adopt industry-leading numerical control automatic welding technology and fully automatic argon arc welding technology. Inert gas is used in the welding process, and the welding part melts instantly at high temperature, thus achieving the integrated welding effect. The weld is non-oxidizing, smooth and uniform, with high strength and strong compression resistance.
2. Excellent surface treatment technology
Internal and external double phosphating and internal phosphating can effectively remove impurities in the cavity, form a rough phosphating layer, enhance the adhesion of the internal anti-corrosion coating and enhance the anti-corrosion protection strength. External phosphating can effectively remove surface impurities, form a flat phosphating film, improve the adhesion effect of primer and enhance the surface oxidation resistance.
3. Cathodic electrophoresis primer
Cathodic electrophoresis technology, which is necessary for painting in automobile industry, is used to attach the primer evenly to the surface of radiator, effectively blocking the corrosion formed by oxygen and making it have the ability to resist harsh environment.
4. Internal anticorrosive coating
Using YDR-2 nano water-based anticorrosive coating patented by the state and advanced vacuum high-pressure automatic filling equipment, after 26 processing steps, a multi-layer internal anticorrosive coating with different functions is formed, which is first-class, compact and uniform, highly effective in oxidation and corrosion resistance, acid and alkali corrosion resistance, non-toxic and non-irritating, sanitary and environmentally friendly. 1. Advanced tube expanding technology adopts advanced hydraulic tube expanding equipment and technology, which makes aluminum and copper tube compound tightly and evenly, greatly improving the heat dissipation.
Efficiency. The technical problem of separation between copper tube and aluminum material due to thermal expansion and cold contraction is completely solved.
2. Full-automatic computer-controlled full-automatic computer-controlled flanging process equipment is suitable for forming an encircling combination between the upright post waterway and the main waterway, thus enhancing welding.
Compressive capacity of this point.
3. The colorful surface is sprayed with Nordson automatic electrostatic spraying assembly line imported from the United States, using high-quality, environmentally-friendly ultraviolet-resistant plastic powder, all made of
Computer control operation, stable spraying, uniform pulverization of radiator surface. After baking at a high temperature of 260 degrees, the surface of the radiator reaches the porcelain effect and is resistant.
Scratch resistance, high temperature and humidity resistance, can effectively resist ultraviolet erosion, avoid fading phenomenon, and ensure that it will remain as bright as new after long-term use.
4. Pretreatment: This process is an important link that directly affects the quality of external spraying. Our factory has complete pretreatment equipment and strictly controls the requirements of pretreatment process. According to the laboratory requirements, we conduct laboratory analysis twice a day to determine the chemical composition content of the bath liquid and ensure the parameter requirements of the bath liquid composition content. The quality of pretreatment is completely guaranteed, thus improving the quality of external spraying of radiator.
5. Quality: Nanshan copper-aluminum composite radiator products have passed the testing of national authoritative radiator testing institutions: corrosion resistance, thermal performance, compressive strength, etc. Tested by National Radiator Quality Supervision and Inspection Center, it meets the requirements of JG220-2007 standard.
