preparation example Construction

[0031] The preparation method of the carrier displacement agent for potassium salt galvanizing comprises the steps of: heating the emulsifier to 90-120°C, vacuum removing water for 3-5h; adding catalyst carbonamide, heating to 180-220°C, and keeping warm for 5-8h ; Then add sulfamic acid and stir at a speed of 150-220 rpm to obtain a carrier displacement agent. Wherein the molar ratio of the emulsifier to the sulfamic acid is (0.8-1.1):(1-1.3), and the molar number of the catalyst is 2-5% of that of the sulfamic acid.

[0032] Preferably, the emulsifier is low-carbon alcohol polyoxyethylene ether, the general formula is R-(CH2CH2O)n-OH, wherein R is C7-10, and n is an integer of 5-15.

Abstract

The invention relates to a carrier walk agent, in particular to a carrier walk agent of kalium-salt zincification and a preparation method thereof. The structural formula of the carrier walk agent ofkalium-salt zincification is alcohol ether sulfonate of RO-(CH2CH2O)nSO3M, wherein R is saturated alkane of C7-10, n is an integer of 5-15, and M is alkali metal. By means of the carrier walk agent, the zinc applying speed is increased, and the working efficiency is improved; the plating speed can be increased by 25%-30%, and the working efficiency is improved; and under the condition of many decomposers, the utilization ratio can reach 98% or above, and the electrical conductivity is good.

Description

technical field [0001] The invention relates to a carrier displacement agent, in particular to a carrier displacement agent for potassium salt galvanizing and a preparation method thereof. Background technique [0002] Chloride galvanizing is a bright galvanizing process developed in the early 1980s. This process is widely used for its stable plating solution, high current efficiency, fast deposition speed, good dispersion ability, and simple treatment of three wastes. [0003] The galvanizing solution commonly used at present is the zincate plating solution with DE additives. This galvanizing solution has low current efficiency, high energy consumption, poor throwing ability, deep plating ability, poor brightness, and narrow current density range. In recent years, the potassium chloride galvanizing process developed on the basis of ammonium salt has overcome some shortcomings of zincate, solved the pollution problem of cyanide electroplating, and greatly saved energy. ...
