(1) The ultra-thin organic film formed by silane technology can replace the traditional phosphating film. The mass of phosphating film is usually 2-3g/m2, while the mass of silane N coating film is only 0.1g/m2, a difference of about 20 times.
(2) The bonding force between Si -- O -- Me covalent molecules is very strong, so the product is very stable, which can improve the corrosion resistance of the product.
(3) easy to use, easy to control, only need to control the pH value and conductivity, no need to control free acid, total acid, accelerator, zinc, nickel, manganese content and temperature and many other parameters, like phosphating solution.
(4) Save energy, can be operated at room temperature or low temperature, energy costs are reduced.
(5) Excellent environmental performance, no harmful heavy metals, no waste residue, less waste water discharge, easy treatment, if the installation of filter and ion exchanger, can do closed cycle use.
(6) strong applicability: suitable for impregnation, spraying and other treatment methods.
(7) multi-metal processing process: cold rolled sheet, hot galvanized sheet, electrogalvanized sheet, coated sheet, aluminum and other different sheet can be mixed line processing.
(8) Simple process and short process.
(9) Low comprehensive cost, low product consumption and low cost of three wastes treatment.
(10) ComPATIble with the original coating process and coating equipment, without equipment transformation, only need to replace the phosphating liquid, can be put into production.
