The world's advanced and environmentally friendly coating technology, jumeite, is a surface treatment technology advocated by takle Shamrock company of Japan.
In recent years, due to the increasingly serious environmental problems, the formulation of laws and regulations on the control of hazardous substances has been strengthened all over the world.
Taking European and American countries as the center, it is beginning to develop the trend of limiting and reducing the application of hexavalent chromium compounds by formulating environmental laws.
Jumeite is a kind of water-soluble completely chromium free surface treatment technology without harm to the environment.
Characteristics of jumeite
Don't worry about polluting the environment
1. Use water solubility
Jumeite technology uses water-soluble treatment solution for environmental protection,
Because it dissolves in water,
It can be done with simple equipment, which can be said to be a surface treatment method that is not harmful to the natural environment and operating environment.
2. Completely chromium free
Jumeite technology does not use chromium compounds in processing and coating. It also conforms to ELV specification.
3. Closed processing system
The processing process of jumeite technology is a closed treatment system without drainage. In addition, in the process of coating spraying, the exhaust gas is mainly water vapor, which does not contain harmful substances specified by relevant laws.
2. Excellent corrosion resistance under salt spray test and periodic repeated test conditions
The corrosion resistance of the product is obvious under the conditions of salt spray test and periodic repeated test, and it has excellent anti rust ability.
3. Excellent heat and corrosion resistance
Jumeite coating does not contain crystal water and organic resin, which is easy to make the heat resistance worse. The coating can resist high temperature for a long time.
4. It has the effect of preventing corrosion of dissimilar metal to aluminum materials
The workpieces treated by jumeite can prevent electrochemical corrosion when aluminum, iron and stainless steel bolts are fixed together. This technology is widely used in automobile industry.
5. Good adhesion
After jiumeite treatment, the inner surface of the pipe also has anti rust coating, which has high anti rust ability.
6. Hydrogen embrittlement will not occur
The hydrogen brittleness of the treated materials is higher than that of the untreated materials,
According to the de'er measurement, it is confirmed that the material breakage is the extrusion distance.
There is no need to worry about hydrogen embrittlement after jumeite treatment.
7. It can handle all kinds of metals
In addition to iron and cast iron, stainless steel materials, aluminum materials and powder metallurgy materials can be processed by jumeite technology,
It is widely used.
8. After jumeite treatment, the surface can be sprayed again
The repainting property of jumeite treated surface was confirmed by spraying solvent based melamine resin coating and powder coating.
The results show that no matter which coating has good appearance and grid adhesion.
