济南C型钢脱脂的方法

来源:/ 日期:2022-04-09 发布人:jiangucaigang
不同的加工厂家处理济南C型钢脱脂的方法是不同的,这主要与镀锌生产线的设备设置有关,因此需要不断的进行适应,那么大家在电镀前应该怎么进行脱脂呢?
Different processing manufacturers have different methods for degreasing Jinan C-section steel, which is mainly related to the equipment setting of galvanizing production line, so it needs to be constantly adapted. So how should we degrease before electroplating?
一、溶剂脱脂。
1、 Solvent degreasing.
溶剂脱脂实际上是皂化油和不皂化油在溶剂中的溶解过程。钢铁制品在机械加工过程中,其表面往往附着较厚的油膜,直接化学处理比较困难,通常采用溶剂处理。本方法不适合去除电焊C型钢表面附着的油污。
Solvent degreasing is actually the dissolution process of saponified oil and unsaponifiable oil in solvent. In the process of machining, the surface of iron and steel products is often attached with thick oil film, so it is difficult to directly chemical treatment, and solvent treatment is usually used. This method is not suitable for removing the oil stain attached to the surface of electric welding C-section steel.
二、电化学脱脂。
2、 Electrochemical degreasing.
电化学脱脂是将氢从阴ji析出或将氧从阳极析出,机械剥离附在c型钢表面的油膜,加速油脂乳化的过程。电解脱脂法根据被清洁物体的电极,极性可分为阳极电解脱脂法、阴极电解脱脂法和混合极别电解脱脂法。
Electrochemical degreasing is the process of separating hydrogen from the cathode Ji or oxygen from the anode, mechanically stripping the oil film attached to the surface of C-section steel, and accelerating the emulsification of oil. Electrolytic degreasing method can be divided into anode electrolytic degreasing method, cathode electrolytic degreasing method and mixed electrode electrolytic degreasing method according to the polarity of the electrode of the object to be cleaned.
一般情况下,济南C型钢表面的润滑脂较少。炉焊管是在高温下形成的,在精加工过程中可能会接触到油脂,但这是可以避免的,通常不需要脱脂工艺。焊接时管道与油脂接触机会大,表面常附着在套管油脂上,如果没有脱脂工艺,会给酸洗带来困难,甚至会污染酸洗液。总之,是否采用脱脂,要根据C钢表面原料的具体情况而定。
In general, there is less grease on the surface of Jinan C-section steel. Grease can be formed in the process of high-temperature degreasing, but it is impossible to avoid it in the process of high-temperature degreasing. During welding, there is a great chance of contact between the pipeline and grease, and the surface is often attached to the casing grease. If there is no degreasing process, it will bring difficulties to pickling and even pollute the pickling solution. In short, whether degreasing is adopted or not depends on the specific conditions of the surface raw materials of C steel.
三、化学脱脂。
3、 Chemical degreasing.
一般是指用碱液和碱盐溶液去油。这种脱脂过程是一个复杂的物理化学过程。它是由油膜在表面活剂和碱的作用下产生的。碱性水溶液去除钢表面油脂的机理。
Generally, it refers to removing oil with alkali solution and alkali salt solution. This degreasing process is a complex physical and chemical process. It is produced by oil film under the action of surfactant and alkali. Mechanism of removing grease on steel surface by alkaline aqueous solution.
目前,C型钢热镀锌前的脱脂主要采用化学清洗的方法。脱脂剂也可以循环使用,这有助于脱脂。在循环系统中应该安装一个分离器,将油脂从脱脂液中除去。为了清洁C型钢表面,在从脱脂液中去除C型钢之前,应先去除脱脂液的表面。
At present, the degreasing of C-section steel before hot galvanizing mainly adopts the method of chemical cleaning. Degreaser can also be recycled, which helps degrease. A separator shall be installed in the circulating system to remove the grease from the degreasing solution. In order to clean the surface of C-section steel, the surface of degreasing liquid shall be removed before removing C-section steel from degreasing liquid.
