熱(re)(re)熔(rong)膠(jiao)(jiao)的粘性在(zai)一定(ding)程度上依賴于其熔(rong)化后(hou)的狀態。天冷時，環境溫度降(jiang)低(di)，熱(re)(re)熔(rong)膠(jiao)(jiao)槍加熱(re)(re)后(hou)的熱(re)(re)熔(rong)膠(jiao)(jiao)在(zai)接觸到較冷的物(wu)體表(biao)面時，會更快(kuai)地冷卻凝固。這使(shi)得熱(re)(re)熔(rong)膠(jiao)(jiao)沒(mei)有足(zu)夠的時間充分浸(jin)潤被(bei)粘物(wu)表(biao)面，從(cong)而(er)導致(zhi)粘合力下(xia)降(jiang)。而(er)且，低(di)溫環境可能使(shi)熱(re)(re)熔(rong)膠(jiao)(jiao)的分子活性降(jiang)低(di)，膠(jiao)(jiao)水的流動性變(bian)差，難(nan)以在(zai)被(bei)粘物(wu)表(biao)面形成均勻(yun)的膠(jiao)(jiao)層。
為了(le)解決這(zhe)個問題，可以適當提高使(shi)用(yong)環(huan)境(jing)的溫(wen)度(du)，比如在(zai)室(shi)內使(shi)用(yong)暖(nuan)氣(qi)或加熱(re)設備(bei)。同時，可以調(diao)整熱(re)熔(rong)(rong)(rong)膠(jiao)槍的溫(wen)度(du)設置，將其調(diao)高一些，確保(bao)熱(re)熔(rong)(rong)(rong)膠(jiao)能夠充(chong)分(fen)熔(rong)(rong)(rong)化并保(bao)持良好(hao)的流動(dong)性。在(zai)使(shi)用(yong)熱(re)熔(rong)(rong)(rong)膠(jiao)時，動(dong)作也應盡量迅速(su)，減少熱(re)熔(rong)(rong)(rong)膠(jiao)在(zai)空氣(qi)中暴露的時間，以防止過快冷(leng)卻。另(ling)外，選擇質(zhi)量較(jiao)好(hao)、適應低溫(wen)環(huan)境(jing)的熱(re)熔(rong)(rong)(rong)膠(jiao)產品(pin)也很重(zhong)要。這(zhe)樣，即使(shi)在(zai)寒冷(leng)的天氣(qi)里，也能讓(rang)熱熔膠發揮出較(jiao)好的(de)粘合(he)效果。
