用作金属制件去除油脂和污垢清洗的水基清洗剂,大都是由多种表面活性剂与具有不同效能的助剂组成.按其清洗剂的使用方法,一般是手工清洗和机械法清洗.对用于后一种清洗方法的清洗剂,要求泡沫生成少,消泡速度快.这样就要在清洗剂制造中选用添加有效的消泡剂.一、泡沫的生成清洗剂泡沫的产生,是由于表面活性剂及与所用助剂复配后引起的.众所周知,表面活性剂有一个显著的共同特点,就是比较易于起泡.表面活性剂的起泡性,是由于表面活性剂
For metal parts to remove grease and dirt cleaning water-based cleaning agents, mostly by a variety of surfactants and additives with different effectiveness of composition. According to the use of cleaning agents, usually manual cleaning and mechanical cleaning. Cleaner for the latter method of cleaning, requiring less foam generation, defoaming speed so that we must choose to add an effective defoamer in the manufacture of cleaning agents. First, the formation of foam Cleaner foam is generated Due to the surfactant and the additive used in the complex after the cause.As we all know, there is a significant common feature of surfactants, is relatively easy to foaming.Surfactant foaming is due to the surfactant
