PUR熱熔膠(jiao)不(bu)拉如何做到的(de)？
PUR是一種單液(ye)熱(re)敏(min)固(gu)化型結構膠(jiao)(jiao)(jiao),該產品常溫下(xia)為粘稠液(ye)物體.65℃-85℃條件下(xia)釋放固(gu)化劑迅速具有較高初粘強度(du),24H后(hou)具有最好(hao)強度(du)。用于手(shou)機、柔性曲面屏(ping)手(shou)機中框粘接。具有優良的(de)(de)粘接性能，通過各項測試。并具備(bei)易拆(chai)解性，不(bu)(bu)(bu)損壞物料。PUR熱(re)熔(rong)膠(jiao)(jiao)(jiao)在生(sheng)產應用中，常有出(chu)現拉絲的(de)(de)情況(kuang)，但(dan)這(zhe)并不(bu)(bu)(bu)是膠(jiao)(jiao)(jiao)水(shui)有什么問(wen)題。PUR作(zuo)為一種熱(re)熔(rong)膠(jiao)(jiao)(jiao)，熔(rong)化后(hou)的(de)(de)粘稠度(du)決定斷膠(jiao)(jiao)(jiao)時不(bu)(bu)(bu)可能不(bu)(bu)(bu)產生(sheng)拉絲的(de)(de)情況(kuang)，那么pur熱(re)熔(rong)膠(jiao)(jiao)(jiao)拉絲的(de)(de)原因(yin)有

PUR熱(re)熔膠(jiao)與常規熱(re)熔膠(jiao)對比
PUR 膠(jiao)特(te)(te)性(xing)對比 熱(re)(re)熔(rong)(rong)(rong)(rong)型膠(jiao)粘劑(ji)在(zai)室溫(wen)下是固(gu)體(ti)，加(jia)熱(re)(re)到(dao)一(yi)定溫(wen)度(du)就熔(rong)(rong)(rong)(rong)融成粘稠(chou)的(de)(de)(de)液體(ti)，冷卻到(dao)室溫(wen)后(hou)又變(bian)成固(gu)體(ti)，并有很(hen)強的(de)(de)(de)粘接(jie)作用(yong)，因此人們(men)把(ba)它(ta)稱為(wei)熱(re)(re)熔(rong)(rong)(rong)(rong)型膠(jiao)粘劑(ji)，簡稱熱(re)(re)熔(rong)(rong)(rong)(rong)膠(jiao)。 PUR熱(re)(re)熔(rong)(rong)(rong)(rong)膠(jiao)與熱(re)(re)熔(rong)(rong)(rong)(rong)膠(jiao)的(de)(de)(de)主(zhu)要區別在(zai)于(yu)，普(pu)通(tong)熱(re)(re)熔(rong)(rong)(rong)(rong)膠(jiao)冷卻至室溫(wen)后(hou)變(bian)成固(gu)體(ti)，但加(jia)溫(wen)到(dao)一(yi)定溫(wen)度(du)它(ta)又熔(rong)(rong)(rong)(rong)融變(bian)液體(ti)了。而(er)PUR熱(re)(re)熔(rong)(rong)(rong)(rong)膠(jiao)冷卻至室溫(wen)后(hou)變(bian)成固(gu)體(ti)的(de)(de)(de)同(tong)時又與空氣中的(de)(de)(de)濕氣水分子反應，在(zai)次(ci)加(jia)熱(re)(re)后(hou)不能熔(rong)(rong)(rong)(rong)融。這就是它(ta)們(men)的(de)(de)(de)主(zhu)要特(te)(te)點。
