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 SPCC 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 SPCC 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 SPCC 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 liquid is a light yellow or yellow transparent liquid, his coating component is inorganic salt and high temperature resistant organic resin, is an ideal product to replace chromate coating liquid, for non - oriented silicon steel surface insulation coating treatment. The coating liquid has the characteristics of fast film forming speed, stable film and average coating. The appearance of the insulating coating is silver or gray white, uniform and bright. The machinability does not peel off and does not powder.
Packaging and storage
Packing: 25 kg/ barrel. Other packaging forms can also be provided according to customer requirements.
Storage: can be stored in a cool and humid environment, but must be sealed storage, according to the chemical storage and storage, winter attention to anti-freezing, need to cover the bucket with a layer of quilt, to prevent the coating liquid in the bucket frozen.
Shelf life: 6 months, 5 ~ 40 ℃. The color of solution may change with storage time, without affecting performance.
With the development and improvement of people's living standards, countries pay more attention to environmental issues, and will put forward greater requirements on the non-oriented silicon steel coating liquid. In addition to meeting the basic performance requirements of silicon steel sheet, it must also meet the environmental protection requirements. At present, there are still some problems in the non-oriented silicon steel chromium-free water-based coating liquid used in domestic production. Inorganic component proportion is less, generally accounting for 10-35% of the solid component, inorganic component proportion is less, coating appearance is good, good performance, in these aqueous solutions, also more or less use of some volatile organic solvents, some of these solvents are non-toxic, some are toxic, this is a direction of improvement in the future, Minimize or do not use volatile non-toxic or low toxic organic solvents, do not use toxic organic solvents
Different curing processes have different effects on the properties of coatings. When the curing process is 400℃+20s, the performance of the coating is the best, bt-2365 better covered the silicon steel substrate, the coating is compact and uniform, the protection rate is as high as 99.53%. In the 5h neutral salt spray experiment, the corrosion area is only 6%, the electrochemical parameters are significantly better than other conditions, and the insulation resistance value reaches 300Ω·mm²
