注膠機(jī)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(jī)中，點(diǎn)膠一次與N、P、S等有機(jī)物元素發(fā)生化學(xué)反應(yīng)后會(huì)迅速反應(yīng)，這就是常說(shuō)的雙液點(diǎn)膠機(jī)硅膠中毒現(xiàn)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(jī)中毒原因分析:
　　Cause analysis of double liquid rubber machine poisoning:

　　雙液點(diǎn)膠機(jī)使用硅酮時(shí)，需要硅酮的加成反應(yīng)，即硅酮?dú)滏I加成反應(yīng)和硅酮鍵加成反應(yīng)。由于加成反應(yīng)需要金屬鉑作為原料，所以兩者的混合物產(chǎn)生一種不穩(wěn)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(jié)構(gòu)或復(fù)合結(jié)構(gòu)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程或養(yǎng)護(hù)和含有催化劑可以添加到成型(“Pt”反應(yīng),任何材料(兩表面接觸,等等)在正常養(yǎng)護(hù)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.
　　如果硅橡膠不是治愈(反應(yīng)前后的國(guó)家仍處于液體狀態(tài)),或治療不完整(硅橡膠固化后不能達(dá)到所需的彈性體或硬度或固化后表面變得粘),這種現(xiàn)象是催化劑“中毒”現(xiàn)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(jī)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(jī)硅中毒，避免在雙液澆注機(jī)中接觸含磷、硫、氮的有機(jī)化合物，或避免在雙液澆注機(jī)中同時(shí)使用聚氨酯、環(huán)氧樹脂、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(jī)在使用不同廠家的硅膠時(shí)，原雙液點(diǎn)膠機(jī)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(xiàn)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.
