我公司拥有全自动的磷化加工车间。有四条自动化磷化加工流水线，主要针对锌磷化或锰磷化，可以为客户提供各种高质量的产品要求。盐雾时间可达72小时以上。外观膜层均匀一致，颜色可根据客户的要求来制定工艺路线。 我们欢迎社会各界表面处理行业人士来我司考察，做技术交流。只有相互学习才能提高自己。---上海路丰助剂有限公司 所谓磷化就是通过化学反应和电化学反应在钢铁表层磷化成含有盐的覆盖的膜。简单的讲，上海磷化加工是工件基体和特殊的药水产生反应，形成自身转化的产品。但是化学反应的前提是钢铁工件的点位要高于磷化药水中的点位。 从细节来讲，钢铁件和磷化剂接触在规定的酸碱值，温度，酸度，应力，时刻，溶剂状况下，通过繁杂的化学处理和电化学处理，在工件表面生成一定厚度的带有6种结晶水的磷化盐结晶和不定性的转化膜层。这种膜可以使钢铁表面从导体变为绝缘体，阻止钢铁生锈。化学反应包含有的水解和电离。还有氧化。和钢铁离子团还原与沉淀。电反应是因为金属表层存在若干微型阴阳极和压力集中的地方的电位比钢铁硬，形成微电流。 带锈的钢铁件和接触发生乳化除油，依靠表面活性成分的影响，降低表面油层的应力，与此同时渗透在油层下的酸根与锈作用，也会加速油层的脱离。脱离表面的油性物质被脱脂剂乳化。以防再次聚集成液体。 my company has a fully automatic phosphating processing workshop. has four automation phosphating processing production line, mainly in zinc phosphate or manganese phosphate, can provide all kinds of high quality product requirements. salt fog time is 72 hours. exterior film uniform, color according to the customer's request to make process route. we welcome a society to all circles personage surface treatment industry to our investigation, technical exchanges. only learn from each other to improve yourself. - shanghai road feng auxiliaries co., ltd the so-called phosphating is through the chemical reaction and electrochemical reaction in the iron and steel surface phosphating into contain phosphate coverage of membrane. simply speaking, shanghai phosphating processing is the matrix and special potion produce reaction, form their own transformation product. but chemical reaction is the premise of steel workpieces point higher than the phosphating liquid medicine point. from detail speaking, iron and steel parts and phosphating agent contact in the provision of ph, temperature, acidity, stress, time, solvent situation, through the complex chemical process and electrochemical treatment, in the workpiece surface formation with a certain thickness 6 kinds of water of crystallization of phosphate salt crystallization and qualitative conversion coating layer. this film can make the steel surface from the conductor into insulators to prevent steel rust. chemical reaction contains phosphating solution hydrolysis and ionization. and oxidation. linhua fluid and steel ion mass reduction and precipitation. electric response because metal surface there are some miniature yin and yang pole and stress concentration of local potential than steel hard, forming a micro electric current. rusted steel parts and phosphatization liquid contacts occur emulsion degreasing, rely on the surface active ingredients of effect, reduce the surface stress of the reservoir, and the same time permeability in the reservoir of acid radical and rust role, will also accelerate the reservoir from. from the surface of the oily substance was degreasing agent emulsion. in case again gathered into liquid.
