一、前言 磷化剂系列产品用于金属表面前处理上,金属表面处理是涂装重要环节之一。在国民经济各部门占有重要的位置。例如:汽车、摩托车、自行车、冰箱、洗衣机等金属壳体和金属零部件在涂装之前都必须进行表面处理。高碳钢丝冷拔及钢管拉拔都需要进行磷化处理。总之,在国民经济各部门,凡在喷漆或涂塑之前的金属部件都要进行磷化前处理。 二、磷化反应机理(反应式略) 三、产品及工艺 金属表面处理剂包括:脱脂剂、除锈剂、表面调整剂、加速剂、调节剂、磷化剂、除渣剂、水处理剂、油漆凝固剂。 磷化处理工艺(略) First, the preface Phosphating products for metal surface pre-treatment, the metal surface treatment is an important part of painting. In all sectors of the national economy occupies an important position. For example, metal housings and metal parts such as automobiles, motorcycles, bicycles, refrigerators, washing machines, etc. must be surface-treated before painting. High-carbon steel wire drawing and drawing of steel are required phosphating. In short, in all sectors of the national economy, where the metal parts before painting or plastic coating should be pre-phosphating. Second, the phosphating reaction mechanism (reaction slightly) Third, the product and process Metal surface treatment agents include: degreasing agents, rust remover, surface conditioning agents, accelerators, regulators, phosphating agents, deslagging agent, water treatment agent , Paint coagulant. Phosphating process (abbreviated)
