- SHENYANG
Silane treatment technology is a relatively mature new nano-scale metal pretreatment technology at present. It replaces the traditional iron-based and zinc-based phosphating products.silane surface treatment agent for GA does not contain harmful heavy metal ions such as nickel, zinc, and manganese, and will not pollute the environment;
There is no slag in the silane treatment process, the treatment time is short, the control is simple, and the maintenance is simple; silane treatment agent pre-coating for GA can also treat a variety of metal substrates such as cold-rolled steel, aluminum, galvanized steel, and coated plates in line, providing them with superior anti-corrosion properties.
surface pretreatment agent for GA is gradually replacing the original pretreatment process with its excellent environmental protection and energy-saving performance.
Second, the chemical principle of silane treatment
The product is based on polymers with organosilane functional groups, which can provide us with the required anti-corrosion and enhanced coating adhesion requirements.
bt-2365 non - oriented silicon steel environmental protection liquid is mainly composed of inorganic components and high temperature resistance of organic resin materials. Among them, inorganic components can make the insulation coating processed with high hardness, good weldability, because welding will release a lot of temperature, so at this time, it needs the characteristics of organic resin resistance to high temperature to avoid the release of harmful gases, high hardness surface to ensure the stability of welding processing coating; Organic resin materials can improve the water resistance, punching and shearing processability of the insulating coating and the adhesion of the coating. Meanwhile, the strong resistance of organic resin to high temperature can greatly avoid the obvious peeling and pulverizing of the coating, which will reduce the weldability of the two non-oriented silicon steels and make it easier for the two welded non-oriented silicon steels to fall directly and injure others. The insulation of the coating is ensured, and a series of environmental problems caused by harmful gases produced by the decomposition of organic materials at high temperature are avoided. Ventilation and exhaust facilities must be installed in the laboratory where harmful gases are produced according to the regulations, and abandoned absorption system and gas filtration device must be installed to ensure ventilation and fresh air. After the laboratory people go out, the Windows must be opened. Keep the air flowing and release the gas that may still remain in the room to keep the gas in the laboratory clean. Non-oriented silicon steel insulation coating not only needs to have excellent application performance, but also needs to have green environmental protection. Many countries have formulated and implemented corresponding environmental protection laws and regulations. Europe has formulated a series of laws and mandatory regulations such as EU directive, ROHS and REACH, which prohibit or strictly limit the content of hexavalent chromium. In order to promote the transformation and upgrading of China's iron and steel industry, the Ministry of Industry and Information Industry has formulated the "Twelfth Five-Year Plan" Development Plan of Iron and Steel industry, which lists electric steel environmental protection coating as an important direction for industry upgrading. With the rapid development of domestic industry, the development direction of coating is also toward the direction of environmental protection and high functional development. A series of environmental protection coating products of various types, different uses and different properties have been formed, which can meet the needs of different application fields for the performance of silicon steel coating.
