Panzer Lacquers / Lacquering chemistry 漆的化学工艺 Lacquer 漆 Liquid lacquer: 液体漆 complex mix of liquid and solid components 固、液态成分混合物 intermediate on the way to a solid coating on the foil 形成箔面固态涂层的中介 there also exist solid lacquers: powder lacquers 固体漆如粉末漆同样存在 Question: Why does the lacquer contain these many components? 问题：为什么漆中含有这么多成分？ Each of the components is of importance for one of the processing steps through which the lacquer passes during its lifetime. 每个成分都对漆的某一形成步骤至关重要。 Processing steps of lacquer at KURZ 库尔兹的制漆过程 Components of a lacquer formula制漆步骤 Classification of the lacquer components漆层成分的分类 Classification according to volatile and non-volatile components按挥发性和不挥发性分类 Additives添加剂 Additives添加剂 Special part of the additives添加剂的特殊部分 Often the performers of the main functions in the lacquer do not harmonize very well. 通常漆的主要成分执行元素相互之间并不十分和谐 Additives improve the teamwork.添加剂可以提高整个过程的质量 Additives添加剂 Range of application:应用范围 mediating function in the lacquer制漆中的中介作用 wetting agent润湿剂 dispersing agent 分散剂 rheologic additive流变添加剂 mediating function to the substrate对基材的中介作用 spreading agent粘贴剂 modification of properties更改特性 UV-stabilisers 抗UV稳定剂 improvement of the surface smoothness改变表面光滑度 Binder薄膜生成器 Function of binders薄膜生成器的功能 Function:功能 form the solid layer after drying在烘干后形成固体层 the way of film former determines the property of the layer (flexibility, chemical resistance, heat resistance, etc.)薄膜生成器可决定固体层的特性（弹性、抗化学品、抗高温等） Binder: 薄膜生成器Physical film forming膜的物理形成 Physical film forming: cohesion内聚力 The molecules of the film former stock close together duringevaporation在蒸发中膜板紧密联合在一起 Chemical film forming化学薄膜形成 Chemical film forming: linking结合 Chemical film forming膜的化学形成 The chemical nature of linking points连结点的化学特性 Gives the name for the binder给生成器命名 determines the chemical and mechanical properties of the film决定膜的化学和机械特性 Solvents 溶解剂 Solvents in lacquers漆中的溶解剂 Main task: 主要任务 dissolve b
