盡管它們(men)的(de)名稱相似，但本質上卻有(you)很大的(de)差別。讓我們(men)來(lai)一一了解、比較(jiao)。
熱(re)(re)熔(rong)(rong)(rong)膠是(shi)一(yi)(yi)種熱(re)(re)塑性(xing)樹(shu)脂膠粘劑，其(qi)產品種類豐(feng)富，應(ying)用(yong)范(fan)圍(wei)廣(guang)。按照其(qi)物理形態不(bu)(bu)同可以分為：熱(re)(re)熔(rong)(rong)(rong)膠棒，熱(re)(re)熔(rong)(rong)(rong)膠塊(kuai)，熱(re)(re)熔(rong)(rong)(rong)膠粒，熱(re)(re)熔(rong)(rong)(rong)粉(fen)，熱(re)(re)熔(rong)(rong)(rong)膠膜等。本質(zhi)上，熱(re)(re)熔(rong)(rong)(rong)膠是(shi)指(zhi)在化(hua)學性(xing)質(zhi)不(bu)(bu)變的情況下，起物理狀態會隨著(zhu)溫度(du)改變而變化(hua)的一(yi)(yi)種膠粘劑。在自然溫度(du)下，熱(re)(re)熔(rong)(rong)(rong)膠通常(chang)為塊(kuai)狀固(gu)體，非常(chang)便于(yu)包(bao)裝，運輸和存(cun)儲。其(qi)應(ying)用(yong)范(fan)圍(wei)相(xiang)對其(qi)他膠水來說更廣(guang)，例如：熱(re)(re)熔(rong)(rong)(rong)膠可用(yong)于(yu)蓄電(dian)池、汽車(che)內飾、日化(hua)包(bao)裝、紙(zhi)品包(bao)裝、箱包(bao)服飾、鞋材復合、墻貼/墻紙(zhi)等多個領域。
