注膠機在電子通信行業(yè)的生產(chǎn)中占有重要的地位。而在雙液點(diǎn)膠機中，點(diǎn)膠一次與N、P、S等有機物元素發(fā)生化學(xué)反應后會(huì )迅速反應，這就是常說(shuō)的雙液點(diǎn)膠機硅膠中毒現象。
　　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.
　　雙液膠機中毒原因分析:
　　Cause analysis of double liquid rubber machine poisoning:

　　雙液點(diǎn)膠機使用硅酮時(shí)，需要硅酮的加成反應，即硅酮氫鍵加成反應和硅酮鍵加成反應。由于加成反應需要金屬鉑作為原料，所以?xún)烧叩幕旌衔锂a(chǎn)生一種不穩定的化合物。
　　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.
　　這種混合材料,很容易受到一些物理和化學(xué)結構或復合結構發(fā)生變化時(shí),就很容易失去催化活性氫硅和乙烯基硅債券,如果添加到硅膠硫化過(guò)程或養護和含有催化劑可以添加到成型(“Pt”反應,任何材料(兩表面接觸,等等)在正常養護條件。
　　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.
　　如果硅橡膠不是(反應前后的仍處于液體狀態(tài)),或不完整(硅橡膠固化后不能達到所需的彈性體或硬度或固化后表面變得粘),這種現象是催化劑“中毒”現象的發(fā)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".

　　介紹了一種避免雙組點(diǎn)膠機硅膠中毒的方法
　　This paper introduces a method to avoid silica gel poisoning of double group dispenser
　　一、避免有機硅中毒，避免在雙液澆注機中接觸含磷、硫、氮的有機化合物，或避免在雙液澆注機中同時(shí)使用聚氨酯、環(huán)氧樹(shù)脂、不飽和聚酯、縮合型RSP硅橡膠等產(chǎn)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.
　　有一種雙組點(diǎn)膠機在使用不同廠(chǎng)家的硅膠時(shí)，原雙液點(diǎn)膠機將硅膠從料筒到膠泵逐漸清理干凈，以避免膠源密封中毒現象。
　　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.
