Embodiment 1-14

[0033] In order to verify the effect of the additive of the present invention, the applicant has carried out experimental verification respectively, and the contents of the experiment are as follows:

[0034] 1. Analysis of plating effect;

[0035] (1) preparation of plating flux;

[0036] Add water into the plating bath, then add 110-120g zinc chloride per liter of water, 150-160g ammonium chloride, and add zinc chloride and ammonium chloride, and additives (if any) to dissolve, then heat to 60°C to obtain a plating flux. Take a Q235 steel sheet with the same specification of 5cm*10cm*0.3cm, pickle, wash with water in turn, weigh after drying, and immerse in different fluxing solutions for 20 minutes.

[0037] After taking it out, observe the drying condition of the surface moisture, and record the drying time. After the moisture is dried, weigh and calculate the deposition amount of the flux salt film, and observe the state of the salt film. This experiment investigates ...

Abstract

The invention relates to an additive for plating assisting, a plating assisting solution and a hot-dip plating method in the technical field of chemical engineering. The additive for plating assistingcomprises a chemical compound which is as shown in the formula I (Please see the formula I in the specification.), wherein R1 represents C12-16 alkyl radical, R2 represents methyl or hydroxypropyl, R3 represents one of hydroxyethyl, hydroxypropyl and dihydroxy propyl, R4 represents one of methyl, hydroxyethyl and dihydroxy propyl, and X represents one of Cl, Br and I. According to the additive, better interface wettability between molten coated metal and workpieces can be achieved, and skip plating is prevented; and meanwhile, the adhesion amount of a plating assisting agent is reduced, the drying process is accelerated, the risk of accidents such as scalds is reduced, the dip plating time is shortened, and material consumption is reduced.

Description

Contents of the invention [0001] The invention belongs to the technical field of chemical industry, and in particular relates to an additive for plating flux, a plating flux solution and a hot-dip plating method. Background technique [0002] The surface of the metal material is coated with other metal or non-metal protective layer, which can effectively prevent the corrosion of the base metal material. The hot-dip metal plating process, including hot-dip galvanizing, hot-dip galvanized aluminum alloy, and hot-dip aluminum plating, mostly adopts the solvent method. The principle is to immerse the workpiece in the molten metal to be plated, lift the workpiece, and its surface will be ready after cooling. Covered with a thin layer of coating, the corrosion resistance is greatly improved, materials and resources can be saved, and good economic and environmental benefits can be exerted. The quality of the coating directly affects the corrosion resistance. Therefore, before the ...
