  注胶机在电子通信行业的生产中占有重要的地位。而在双液点胶机中░,点胶一次与N•●、P•●、S等有机物元素发生化学反应后会迅速反应░,这就是常说的双液点胶机硅胶中毒现象。
  Glue injection machine plays an important role in the production of electronic communication industry. In the double liquid dispensing machine, the chemical reaction between the dispensing machine and organic elements such as N, P, s will be rapid, which is often referred to as silicone poisoning.
  双液胶机中毒原因分析:
  Cause analysis of double liquid rubber machine poisoning:
  双液点胶机使用硅酮时░,需要硅酮的加成反应░,即硅酮氢键加成反应和硅酮键加成反应。由于加成反应需要金属铂作为原料░,所以两者的混合物产生一种不稳定的化合物。
  When using silicone in double liquid dispenser, the addition reaction of silicone is needed, that is, the hydrogen bond addition reaction of silicone and the bond addition reaction of silicone. Because the addition reaction requires platinum as the raw material, the mixture of the two produces an unstable compound.
  这种混合材料,很容易受到一些物理和化学结构或复合结构发生变化时,就很容易失去催化活性氢硅和乙烯基硅债券,如果添加到硅胶硫化过程或养护和含有催化剂可以添加到成型(“Pt”反应,任何材料(两表面接触,等等)在正常养护条件。
  This kind of hybrid material is very vulnerable to some changes in physical and chemical structure or composite structure, it is easy to lose catalytic active silicon hydrogen and vinyl silicon bonds, if added to the silicone vulcanization process or curing and containing catalyst can be added to the molding ("PT" reaction, any material (two surface contact, etc.) in normal curing conditions.
  如果硅橡胶不是治愈(反应前后的国家仍处于液体状态),或治疗不完整(硅橡胶固化后不能达到所需的弹性体或硬度或固化后表面变得粘),这种现象是催化剂“中毒”现象的发生。
  If the silicone rubber is not cured (the country before and after reaction is still in liquid state), or the treatment is incomplete (the silicone rubber cannot reach the required elastomer or hardness after curing or the surface becomes sticky after curing), this phenomenon is the occurrence of catalyst "poisoning".

  介绍了一种避免双组点胶机硅胶中毒的方法
  This paper introduces a method to avoid silica gel poisoning of double group dispenser
  一•●、避免有机硅中毒░,避免在双液浇注机中接触含磷•●、硫•●、氮的有机化合物░,或避免在双液浇注机中同时使用聚氨酯•●、环氧树脂•●、不饱和聚酯•●、缩合型RSP硅橡胶等产品。
  I. avoid organosilicon poisoning, contact with organic compounds containing phosphorus, sulfur and nitrogen in the double liquid pouring machine, or use polyurethane, epoxy resin, unsaturated polyester, condensed RSP silicone rubber and other products at the same time in the double liquid pouring machine.
  有一种双组点胶机在使用不同厂家的硅胶时░,原双液点胶机将硅胶从料筒到胶泵逐渐清理干净░,以避免胶源密封中毒现象。
  When using silica gel from different manufacturers, the original double liquid dispenser will gradually clean the silica gel from the barrel to the rubber pump to avoid the sealing poisoning of the rubber source.
