Smokeless inorganic salt plating aid
The traditional hot-dip galvanizing solution is mainly composed of zinc chloride and ammonium complex salt. Its performance is to dissolve some ferrous salts and iron ions, and to protect the active surface (i.e. coating aids). Generally, it does not improve and optimize the metal surface, especially for the reaction of zinc iron alloy in the galvanizing process, especially for the body materials The thickness of zinc layer can't be controlled for the defective plating parts, which mainly depends on the insufficient main formula of the solution itself, resulting in too much smoke and dust during the galvanizing process affecting the workshop environment; the smokeless inorganic salt solution can fundamentally solve the shortcomings of the traditional solution formula. It can also solve the micro and macro quality control of zinc coating.
Smokeless inorganic salt solution is a new process formula which is composed of a variety of inorganic salts as the main body of autocatalytic reaction and complex chemical reaction. It can effectively solve the volatile matter of smoke and dust in the workshop and the zinc consumption control in the galvanizing process.
1. The smoke-free plating aid can fundamentally solve the volatile matter and zinc consumption index of smoke and dust which can not be solved by the old zinc ammonium double salt plating aid.
2. It has an excellent protective effect on the active surface of iron ions, and the film is very thin and has good oxidation resistance and high uniformity.
3. The ability of dissolving iron ions and ferrous chloride is very strong, which can make the ferrous salt on the surface of the galvanized body clear well.
4. There are many kinds of microelements and alloy compounds that control the reaction speed of zinc iron alloy in the whole coating, which greatly reduces the growth speed of alloy layer in the process of galvanizing, and the effect of controlling the thickness of zinc layer in 3 minutes is the best.
5. It has a good removal effect on the surface of workpieces with high content of phosphorus, sulfur, manganese, silicon and carbon. The soluble impurities in the solution can be transformed and precipitated by key technologies.
6、 The process tolerance zone of the auxiliary plating solution is very wide, it has good batch production process, and the maintenance is simple and easy to control.
1. Compared with the traditional plating aid formula, the biggest advantage is smoke-free and the volatile matter in the workshop is very low.
2. The bonding strength of the zinc coating is greatly improved, but the zinc coating is reduced by more than 15% ~ 30um% (the same grade)
3. A large amount of ineffective zinc consumption is reduced, and zinc ash and zinc slag can be reduced by 15-25%.
4. The biggest advantage is to save the operation cost and maintenance cost of the dedusting equipment. Smokeless non base salt plating aid, 5mm thick. The temperature of zinc pot is 440 ° C, the thickness of zinc layer is 40-55um, and the zinc ash is 3.46kg/ton. The effective zinc consumption per ton of workpiece is 16.88kg. The total zinc consumption is 3.46 + 16.88 = 20.34kg. There is no data for zinc slag. The natural evaporation is 1.2kg per square meter / 24 hours. It costs about 6-15 yuan for each ton of plating aid.
