山东模具制造厂家—— 塑料外壳注塑加工除油剂如何选择?

塑料外壳加工白电油的学名叫正庚烷,具有高脂溶性和高挥发性,在塑料制品电镀加工中去污能力强,所以在工业上常常被用做清洗剂,在五金、电子以及塑料电镀等职业的运用特别广泛。可是,白电油实际上是一种十分危险的物质。
The scientific name of white electric oil for plastic shell processing is n-heptane, which has high fat solubility and high volatility, and has strong decontamination ability in the electroplating process of plastic products. Therefore, it is often used as cleaning agent in industry, especially in hardware, electronics and plastic electroplating. However, white oil is actually a very dangerous substance.
塑料外壳加工外表电镀职业,如ABS、PC、TPU等原料注塑工艺中,运用了脱模剂导致素材外表沾有油污,在进行电镀时出现油点油斑以及油窝等现象,为了解决这一现象,电镀职业一般是运用白电油来浸泡清洗。塑胶件外表上是看不见摸不着,可是等生产出来后却发现一堆的油污不良品。
In the plastic shell processing surface electroplating profession, such as ABS, PC, TPU and other raw materials injection molding process, the use of mold release agent causes the material surface to be stained with oil, oil spots and oil pits appear during electroplating. In order to solve this problem, the electroplating profession generally uses white electric oil to soak and clean. Plastic parts can't be seen or touched on the surface, but after they are produced, they find a pile of greasy defective products.
这是每个做真空镀膜的厂家都会遇到并且十分头痛的事情,由其是做生产一线的技术人员确是有苦说不出,找注塑厂呢人家说没有脱模剂,也没有机油污染,确实,素材外表彻底看不到油污,找上头呢上头会觉得你技术问题,不好搞。其实它只是看不到罢了,油污确实是存在的,它经过了注塑机的高温有的已经固化了,有的会渗透到素材表层,一般肉眼是看不出来,可是一上UV底就全起油窝,做出一堆堆不良品来,所曾经处理就变得十分重要了。
This is something that every manufacturer of vacuum coating will encounter and have a headache. The technicians in the production line can't tell. When they look for the injection molding plant, they say that there is no mold release agent or oil pollution. Indeed, there is no oil stain on the surface of the material. When they look for it, they will think that your technical problems are not easy to handle. In fact, it just can't be seen. Oil stains do exist. Some of them have solidified after the high temperature of the injection molding machine, and some of them will penetrate into the surface of the material, which can't be seen by the naked eye. However, once the UV bottom is filled with oil pits and a pile of defective products are made, the treatment has become very important.
