熱熔(rong)膠為什么粘不牢

熱(re)熔(rong)(rong)膠(jiao)(jiao)粘不(bu)牢(lao)的(de)原因有很多，可(ke)能(neng)是因為選用的(de)熱(re)熔(rong)(rong)膠(jiao)(jiao)品種(zhong)不(bu)對、熔(rong)(rong)化溫度不(bu)夠、沒(mei)有給被粘接物施加(jia)足夠的(de)壓(ya)力、沒(mei)有留給熱(re)熔(rong)(rong)膠(jiao)(jiao)足夠多的(de)硬化時間(jian)、被粘接物表面沒(mei)有被清理干凈(jing)、熱(re)熔(rong)(rong)膠(jiao)(jiao)變質、滲透性能(neng)不(bu)足、生產操作(zuo)不(bu)得當、沒(mei)有預(yu)熱(re)到一定時間(jian)、過了保質期、用膠(jiao)(jiao)量不(bu)足、基材(cai)太冷(leng)、基材(cai)受潮等。

熱熔膠用(yong)吹(chui)風(feng)機(ji)可以(yi)融化嗎(ma)

凝固的熱(re)熔膠只(zhi)要(yao)其(qi)(qi)溫度(du)(du)達到90度(du)(du)后，便會開始(shi)出現軟(ruan)化，當溫度(du)(du)上升至120度(du)(du)后，就會快(kuai)速融(rong)化，而開啟吹(chui)風(feng)機(ji)熱(re)風(feng)是(shi)可以讓其(qi)(qi)融(rong)化的，只(zhi)不(bu)過(guo)效率比較慢，需要(yao)長時間使(shi)用吹(chui)風(feng)機(ji)。

熱熔(rong)膠遇水容易脫落(luo)嗎

熱(re)熔(rong)(rong)膠(jiao)(jiao)遇水(shui)(shui)(shui)是(shi)(shi)(shi)否容(rong)易(yi)脫(tuo)膠(jiao)(jiao)，其(qi)實就是(shi)(shi)(shi)考(kao)量(liang)的(de)熱(re)熔(rong)(rong)膠(jiao)(jiao)的(de)耐(nai)水(shui)(shui)(shui)洗性(xing)能(neng)。不(bu)同材質特性(xing)的(de)熱(re)熔(rong)(rong)膠(jiao)(jiao)，它(ta)的(de)耐(nai)水(shui)(shui)(shui)洗性(xing)能(neng)是(shi)(shi)(shi)不(bu)一樣的(de)。pa、pes、tpu材質的(de)熱(re)熔(rong)(rong)膠(jiao)(jiao)都具(ju)備耐(nai)水(shui)(shui)(shui)洗的(de)特點，這三種材質的(de)耐(nai)水(shui)(shui)(shui)洗性(xing)能(neng)排(pai)名是(shi)(shi)(shi)pes強于tpu、tpu強于pa。這些耐(nai)水(shui)(shui)(shui)洗特性(xing)的(de)熱(re)熔(rong)(rong)膠(jiao)(jiao)，在遇水(shui)(shui)(shui)后是(shi)(shi)(shi)基(ji)本是(shi)(shi)(shi)不(bu)需(xu)要(yao)擔心是(shi)(shi)(shi)否脫(tuo)膠(jiao)(jiao)這樣的(de)問題。

熱熔膠怎么去除

如果要(yao)把(ba)熱(re)(re)(re)熔(rong)(rong)(rong)膠(jiao)去(qu)除(chu)的話，可(ke)(ke)以在熱(re)(re)(re)熔(rong)(rong)(rong)膠(jiao)的表面涂抹一些醫(yi)用酒精、風油精、丙酮、汽油、熱(re)(re)(re)熔(rong)(rong)(rong)膠(jiao)清洗劑。也可(ke)(ke)以把(ba)沾有(you)熱(re)(re)(re)熔(rong)(rong)(rong)膠(jiao)的物品放到冰箱(xiang)的冷(leng)凍室，等到出現硬化現象后(hou)就可(ke)(ke)以把(ba)熱(re)(re)(re)熔(rong)(rong)(rong)膠(jiao)撕掉了。或者使用熱(re)(re)(re)水、熨斗把(ba)熱(re)(re)(re)熔(rong)(rong)(rong)膠(jiao)弄熱(re)(re)(re)，使熱(re)(re)(re)熔(rong)(rong)(rong)膠(jiao)出現軟化現象，從而(er)去(qu)除(chu)掉熱(re)(re)(re)熔(rong)(rong)(rong)膠(jiao)。
