电镀前对彩钢板进行脱脂的方法

来源:http://www.jnjgcg.com/ 日期:2022-12-22 发布人:jiangucaigang
因彩钢板所具有的特点,所以它普遍用于钢结构建筑的檩条、墙梁,亦可自行组合成轻量型屋架、托架等建筑构件,还可用于机械轻工制造中的柱、梁和臂等。电镀前对济南彩钢板进行脱脂的方法有以下几种。
Because of its characteristics, color steel plate is widely used for purlins and wall beams of steel structure buildings, and can also be combined into lightweight roof trusses, brackets and other building components, and can also be used for columns, beams and arms in mechanical light industry manufacturing. There are several ways to degrease Jinan color steel plate before electroplating.
用有机溶剂脱脂。有机溶剂脱脂实际上是皂化油和不皂化油在有机溶剂中的溶解过程。当钢铁产品被加工时,表面经常粘附着厚厚的油膜。很难用化学方法,通常是有机溶剂直接处理。这种方法不适合于在焊接彩钢板的生产过程中去掉粘附在表面上的油。
Degrease with organic solvent. Organic solvent degreasing is actually the dissolution process of saponified oil and unsaponifiable oil in organic solvent. When steel products are processed, thick oil film is often adhered to the surface. It is difficult to use chemical methods, usually organic solvents for direct treatment. This method is not suitable for removing the oil adhered to the surface during the production process of welding color steel plates.
化学脱脂。通常指用碱和碱性盐的水溶液处理以除去油脂。这个脱脂过程是一个相当复杂的物理和化学过程。油膜是在表面活性剂和碱的作用下产生的。碱性水溶液去掉钢铁表面油脂的机理。
Chemical degreasing. It usually refers to treating with aqueous solution of alkali and alkaline salt to remove grease. This degreasing process is a rather complex physical and chemical process. The oil film is produced under the action of surfactant and alkali. The mechanism of removing grease from steel surface by alkaline aqueous solution.

目前,彩钢板热镀锌前的脱脂主要是通过化学清洗进行的。脱脂液也可以循环使用,可以提升脱脂效果。分离器应安装在循环系统中,以去掉脱脂液体中的油脂。为了清洁彩钢板表面,在从脱脂液中去掉彩钢板之前,应去掉脱脂液表面的油脂。
At present, degreasing of color steel plate before hot galvanizing is mainly carried out through chemical cleaning. Degreasing liquid can also be recycled to improve the degreasing effect. The separator shall be installed in the circulating system to remove the grease from the degreasing liquid. To clean the surface of color steel plate, remove the grease on the surface of degreasing solution before removing the color steel plate from the degreasing solution.
通常,彩钢板表面附着的油脂较少。炉焊管是在高温下形成的,在精加工过程中可能会与油脂接触,但这是可以避免的,通常不提供脱脂工艺。电焊管和油脂之间有许多接触的机会。套筒润滑脂经常粘附在表面上。如果不设置脱脂工序,会给酸洗带来困难,甚至污染酸洗液。是否使用脱脂应根据原材料彩钢板的具体表面条件来决定。
Generally, there is less grease on the surface of color steel plate. Furnace welded pipe is formed under high temperature and may contact with grease during finishing, but this can be avoided and degreasing process is usually not provided. There are many opportunities for contact between welding tubes and grease. Sleeve grease often sticks to the surface. If the degreasing process is not set, it will bring difficulties to the pickling, and even pollute the pickling solution. Whether to use degreasing shall be determined according to the specific surface conditions of the raw material color steel plate.
