4) on the middle layer, coat coloration protection coating layer again.
The essence of step 3) is glucose and silver ammino solution generation silver mirror reaction, and the silver layer that produces one deck light is attached on the ready-made bottom.Use palladium carbon catalyst (Pd/C) and ruthenium trichloride as speed and the reduction reaction pair environment requirement of catalyzer to improve reaction.The effect of Palladous chloride PdCl2 and anionic surfactant coconut oil diethanol amide is to improve surface active, and the silver layer that reaction is produced can be evenly distributed in product surface, can prevent part surface and react uneven problem.
Develop corresponding 1#, 2# and 3# proportioning according to variation of temperature throughout the year, concentration needs high point under the low environment of temperature, and concentration low spot under the high situation of temperature can guarantee can both make qualified product under the various environment like this.
Above-mentioned steps 4) coat coloration protection coating layer and can adopt in following three kinds of methods any one:
1, identical with the primer coating electrophoresis method, coating is the acrylic anodic Clear paint.
2, add color-mixing UV light oil above the middle layer, solidify color-mixing UV light oil with uviolizing then.
3, use toning acrylic-amino Resins, epoxy baking vanish above the middle layer.
Compared with prior art, the invention has the advantages that:
1, owing to adopt waterborne liquid, do not contain deleterious heavy metal, can accomplish three-waste free discharge.
2, products obtained therefrom has advantages such as corrosion-resistant, wear-resistant, shock-resistance, and its every performance is not less than electro-plating method.
3, the required equipment cost of this method is significantly less than the cost of electroplating device.
4, energy consumption is low, can realize automatic production, and production cost is a tradition galvanized 65%.
5, coating rich color, surface color can be allocated arbitrarily, can make shades of colour.
6, method is easy to operate, the processing of can doing over again of product fine rate height, unacceptable product.
