- 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 galvanized steel 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 galvanized 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 galvanized 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 coating is a water as the main solvent of a kind of insulation coating, it has the characteristics
1. Excellent water resistance, solvent resistance and salt spray resistance, suitable for transportation and storage in coastal areas;
2, single component packaging, easy to use, easy to operate and manage, ensure production safety, can be stored for a long time. Bt-2365 compared with bt-2364 non-oriented silicon steel insulation liquid it does not contain chromate, bt-2365 coating components and bt-2364 there is no special additives. And compared with chromium containing coating liquid, longer shelf life, more environmental protection, more convenient production, coating is more stable, more stable, not easy to flake
Bt-2364 is an orange emulsion, although does not contain harmful solvents, but it contains chromic salt, is not allowed, and his solid content by indicating the type of coating roller, his coating is divided into two kinds: light green or yellow green (zinc); White-gray or yellow-white (magnesium series)
Summary: bt-2365 relative to 2364, more environmental protection, simple, safe
Non-oriented silicon steel has excellent electromagnetic properties and is an important energy saving metal functional material. It is mainly used as the core of various kinds of motors and small transformers. In order to improve equipment efficiency and save electric energy, the iron loss of non - oriented silicon steel should be reduced. Eddy current loss (Pe) accounts for about 20% to 40% of the iron loss. Because Pe is proportional to the square of the thickness of the steel plate, the thickness of the steel plate is thinned and stacked to make the core. In order to effectively limit the eddy current loss within each layer of steel plate and reduce the eddy current loss, it is necessary to coat the surface of the silicon steel with a certain insulating property, so that the non-oriented silicon steel has a more energy-saving effect. Generally, the thickness of the insulating coating is between 0.5 ~ 5.0 μm, and it usually has good insulation, adhesion, punching, weldability, heat resistance and corrosion resistance.
Environment-friendly thin coating is semi-organic chromium-free environment-friendly coating, which belongs to C5 thin coating. Its coating liquid is in solution form and no soluble particle filler. The environmentally friendly thin coating is generally water-soluble phosphate coating, which is mainly used to replace the conventional semi-organic chrome-containing coating. Its main components are phosphate and resin. Through formula optimization, the problem that the remaining phosphoric acid is easy to sticky is solved, and it has good insulation, heat resistance and other properties. Suitable for small and medium-sized motor, small transformer products core. Although there is some gap between the heat resistance, corrosion resistance and chromium coating, it has been able to meet the normal use needs of users, and some products have significantly improved the insulation.
