摘    要:机械镀锌工艺中起关键作用的是锌粉团在工件上的吸附、强化和稳定这一过程可以提高沉积速度。采用表面活性剂复合成活化剂,使得被镀表面与锌粉团之间始终保持吸附电位差,形成金属粉快速而稳定地沉积;采用非锡类金属盐和无机酸式氨盐复合成沉积剂,利用金属离子还原的引忸作用和氨基的络合作用使镀层细化,结合强度提高 。

关 键 词:机械镀锌  表面活性剂  快速活化工业

Abstract:Adsorption of zinc powders on surface of work pieces playes an important part in the process of mechanical plating,the strengthening and stabilizing adsorptions can increase the speed of deposition.A new activator compounded with surfactant can always keep up adsorption potential difference between the surface coated and the group of zinc powder,and make zinc powder deposite on the surface rapidly and stably.By introduction of complexation precipitant compounded with non tin and ammino compound coating structure is fine and anchoring strength of coating is improved.
Keywords:mechanical  plating  surfactants
