Abstract
The invention provides a kind of is parent with the chlorine root, contains the complex compound of chemical elements such as zinc, nitrogen and boron, as the plating assistant agent in the pot galvanize operation, can make workpiece in the immersion plating process, realizes the zinc coating of fine texture within one minute.
Description
The present invention relates in hot dip galvanizing process, how to solve the preceding handling problem of workpiece immersion plating.
The pot galvanize operation of now general enterprise, workpiece is handled with hydrochloric acid zincification method before immersion plating, or handles with the hot solution of ammonium chloride, and technology is very unstable, the workpiece to be plated surface often occurs and lack zinc dew iron phenomenon, this situation seems even more serious when immersion plating malleable iron.Up to the present, also there is not a kind of special heat zinc coating auxiliary agent supply on the market.
Purpose of the present invention is that a kind of special heat zinc coating auxiliary agent will be provided, thereby guarantees the normal operation of pot galvanize, and guarantees galvanizing quality and realize the hot dip galvanizing process standardization.
Effect of the present invention and mechanism are the oxide compound of dissolved iron primary surface effectively and the foul that cleans fe-based surface, but do not corrode fresh iron-based face, and zinc particles is provided simultaneously, and can make workpiece in the immersion plating process, successfully realize the zinc coating of fine texture within one minute.Because, this plating assistant agent be a kind of be the complex compound of parent with the chlorine root, wherein contain elements such as zinc, nitrogen and boron, meet the complex acid that becomes a kind of complexity behind the water, the mechanism effect of similar welding fluid is arranged.
The present invention realizes by the following method:
The zinc ammonium chloride solution dehydrates is become white crystalline powder, add the Sodium Tetraborate of 5-10% thereafter.Its chemical ingredients is composed as follows:
The chlorine root accounts for 45%
Zinc particles accounts for 30%
The nitrogen element accounts for 5%
Boron accounts for 4%
Surplus is hydrogen and other impurity.
In force, this powder is dissolved in the water of normal temperature by 20～30%, workpiece that is will be through surface-conditioning clean and that removed rust immerses 5 seconds in the solution, takes out the back drying and can enter immersion plating in the zinc groove.
In addition, this preparation is about to powder after the oven dry of coating bath limit after dewatering once more, be pressed in the zinc liquid and stir, and can remove bubble and impurity in the zinc liquid effectively.
Simultaneously, this preparation also can be made the welding compound of oxygen welding and soldering, during use powder is sprinkling upon on the weld bond to get final product.
The consumption of this preparation in the immersion plating operation is 8～10 kilograms of workpiece per ton.
Claims (2)
1, the present invention is with after the zinc ammonium chloride solution dehydrates, adds 5～10% Sodium Tetraborate again and the heat zinc coating auxiliary agent made, it is characterized in that:
A. the chemical ingredients of heat zinc coating auxiliary agent composition is:
Chloride content 45%
Zinc content 30%
Nitrogen content 5%
Boron content 4%
Surplus is impurity
B. heat zinc coating auxiliary agent is the crystalline powder of white and band color.
2, according to the described composition principle of claim 1, the heat zinc coating auxiliary agent crystalline powder of preparing with muriates such as zinc, ammoniums.
