一般需要热浸渗锌的零件表面大部分都是未经机械加工的(如板材、管材、线材及型钢等),其表面有锈蚀及油污。这些锈蚀和油污会隔绝锌与零件表面基体金属的接触,阻止渗层的形成。为此,必须采用化学或机械方法将零件表面锈蚀及油污清洗干净,然后再涂上一层溶剂,才能进行热浸渗锌。下面就热浸渗锌溶剂问题作一些介绍。一、溶剂的配制热浸渗锌溶剂大体可分为无机物溶剂和有机物溶剂两种。无机溶剂又可 Generally need hot-impregnated parts of the surface of zinc are mostly not machined (such as sheet, pipe, wire and steel, etc.), the surface rust and oil. These rust and oil will isolate the contact of zinc with the base metal of the part surface and prevent the formation of the layer. To do this, you must use chemical or mechanical methods to the parts surface rust and oil clean, and then coated with a layer of solvent, in order to carry out hot infiltration of zinc. The following hot impregnation zinc solvent problems for some introduction. First, the preparation of solvents Hot-impregnated zinc solvent can be divided into two kinds of inorganic solvents and organic solvents. Inorganic solvents can be
