    济南c型钢进行脱脂的方法!

      有许多方法可以使C型钢的表面脱脂。 所使用的方法通常与镀锌线的设备设置有关。 两者需要相互适应。 有几种在电镀前对C型钢进行脱脂的方法。
      There are many ways to degrease the surface of C-beam. The method used is usually related to the equipment setting of the galvanizing line. The two need to adapt to each other. There are several ways to degrease C-beam before electroplating.
      有机溶剂脱脂。 在有机溶剂中脱脂实际上是皂化油和非皂化油在有机溶剂中的溶解过程。 加工钢铁产品时,表面往往会形成一层厚油膜。 通常难以通过化学方法直接对其进行处理,通常通过有机溶剂处理。 对于附着在C型钢生产的电焊表面的油,不宜使用此方法去除油脂。
      Degrease with organic solvent. Degreasing in organic solvent is actually the dissolving process of saponified oil and non saponified oil in organic solvent. When processing iron and steel products, the surface often forms a thick oil film. It is difficult to treat it directly by chemical method, usually by organic solvent. This method should not be used to remove the oil attached to the welding surface of C-beam production.
      化学除油。 通常,将其用碱和碱性盐的水溶液处理以除去油脂。 该脱脂过程是相对复杂的物理和化学过程。 它是通过表面活性剂和碱的作用产生的油膜。 用碱性水溶液除去钢表面油的机理。
      Chemical oil removal. It is usually treated with an aqueous solution of alkali and alkaline salts to remove grease. The degreasing process is a relatively complex physical and chemical process. It is an oil film produced by the action of surfactant and alkali. The mechanism of removing steel surface oil with alkaline aqueous solution.
      当前,C型钢在热浸镀锌之前的脱脂主要通过化学清洗来进行。 脱脂液也可以循环,从而促进脱脂。 分离器安装在循环系统中,以去除脱脂液体中的油脂。 为了清洁C型钢的表面,必须先将脱脂液体的表面涂抹,然后再将C型钢从脱脂液中提起。

      At present, the degreasing of C-section steel before hot-dip galvanizing is mainly carried out by chemical cleaning. Degreasing solution can also be recycled to promote degreasing. The separator is installed in the circulation system to remove grease from the degreasing liquid. In order to clean the surface of C-beam, the surface of degreasing liquid must be coated first, and then C-beam can be lifted from the degreasing liquid.
      电化学脱脂。 电化学脱脂是通过使用沉积在阴极上的氢气或将氧气沉积在阳极上来机械分离附着在C型钢表面的油膜并加速油的乳化的过程。 电化学脱脂方法根据被清洗物的电极极性可分为阳极电解脱脂,阴极电解脱脂和混合极性电解脱脂。
      Electrochemical degreasing. Electrochemical degreasing is a process of mechanical separation of the oil film attached to the surface of C-beam and acceleration of oil emulsification by using hydrogen deposited on the cathode or oxygen deposited on the anode. The electrochemical degreasing method can be divided into anode electrolytic degreasing, cathode electrolytic degreasing and mixed polarity electrolytic degreasing according to the polarity of the cleaned electrode.
      通常,C形钢的表面附着的油脂较少。 炉焊管的温度为髙,并且在精加工过程中可能与油脂接触,但是通常可以在不进行脱脂的情况下避免这种情况。 电焊管与油脂接触的机会很多。 该表面经常粘附在套筒上。 如果没有脱脂过程,将导致酸洗困难,甚至污染酸洗液。 简而言之,是否使用脱脂取决于原料C形钢表面的具体条件。
      In general, the surface of C-steel has less grease. The temperature of furnace welded pipe is high, and it may contact with grease during finishing, but it can be avoided without degreasing. There are many opportunities for the electric welding pipe to contact with grease. This surface often adheres to the sleeve. If there is no degreasing process, it will lead to pickling difficulties and even contaminate the pickling solution. In short, the use of degreasing depends on the specific conditions of the raw C-steel surface.
