熱熔膠(jiao)(jiao)的粘(zhan)性(xing)(xing)在(zai)一定程度上(shang)依賴于(yu)其熔化(hua)后的狀態。天(tian)冷時(shi)(shi)，環(huan)(huan)境溫度降(jiang)(jiang)低(di)(di)(di)，熱熔膠(jiao)(jiao)槍加熱后的熱熔膠(jiao)(jiao)在(zai)接觸到較冷的物體表面(mian)(mian)時(shi)(shi)，會更快地冷卻凝(ning)固。這使(shi)得熱熔膠(jiao)(jiao)沒有足夠的時(shi)(shi)間充分浸(jin)潤被粘(zhan)物表面(mian)(mian)，從而導致粘(zhan)合(he)力下降(jiang)(jiang)。而且，低(di)(di)(di)溫環(huan)(huan)境可能使(shi)熱熔膠(jiao)(jiao)的分子(zi)活性(xing)(xing)降(jiang)(jiang)低(di)(di)(di)，膠(jiao)(jiao)水的流(liu)動性(xing)(xing)變差，難(nan)以在(zai)被粘(zhan)物表面(mian)(mian)形成均勻的膠(jiao)(jiao)層。
為(wei)了解決這(zhe)個問題(ti)，可以適當提高使用環境的溫度，比如在室內使用暖氣或加(jia)熱(re)設備(bei)。同時(shi)，可以調整熱(re)熔(rong)(rong)(rong)膠槍的溫度設置(zhi)，將(jiang)其調高一些，確保(bao)熱(re)熔(rong)(rong)(rong)膠能夠充分熔(rong)(rong)(rong)化并保(bao)持良好的流動(dong)(dong)性。在使用熱(re)熔(rong)(rong)(rong)膠時(shi)，動(dong)(dong)作也應盡量迅速，減少(shao)熱(re)熔(rong)(rong)(rong)膠在空氣中暴露(lu)的時(shi)間，以防(fang)止過快冷卻。另外，選(xuan)擇質量較好、適應低(di)溫環境的熱(re)熔(rong)(rong)(rong)膠產(chan)品也很(hen)重要(yao)。這(zhe)樣，即使在寒(han)冷的天(tian)氣里，也能讓熱(re)熔膠發揮出較好(hao)的粘合效果。
