style="text-indent:25px">聚酰胺熱熔膠的種類(lèi)及特點(diǎn)：聚酰胺按其合成工藝路線一般可以分為兩大類(lèi)。一類(lèi)是由二元酸和二元胺縮聚而成。另一類(lèi)是由∞一氨基酸縮聚或由己內(nèi)酰胺開(kāi)環(huán)聚合而得。由于聚酰胺熔點(diǎn)太高，用作熱熔膠時(shí)一般將其制成共聚酰胺，使其具有較低的熔點(diǎn)和較長(zhǎng)的固化時(shí)間，而且它極性強(qiáng)，能產(chǎn)生很大的分子間作用力，具有優(yōu)異的粘接性能。聚酰胺熱熔膠在室溫下呈固態(tài)，在其熔點(diǎn)以上呈液態(tài)。具有流動(dòng)性和潤(rùn)濕能力，待固化冷卻后即形成**度的粘接。聚酰胺熱熔膠可以配制成具有不同軟化點(diǎn)和脆化點(diǎn)的產(chǎn)品，以滿足不同使用溫度的要求。聚酰胺熱熔膠主要分為3類(lèi)： (1)二聚酸型，即二聚酸與脂肪族二胺的縮聚物； (2)尼龍型，即尼龍6、6／12、6／66／10等的共聚物 (3)芳香族二元酸與脂肪族二元胺或脂肪族二元酸與芳香族二元胺的二元或三元共聚物。常用的為前2類(lèi)，第3類(lèi)由于在分子中引入芳香基團(tuán)和其它支鏈以及多元共聚物，使柔性和粘度得以改善。但由于采用的是溶液聚合的制備方法，溶劑分離的后處理不可避免地帶來(lái)環(huán)境污染。南京透明聚酰胺廠家推薦聚酰胺的吸水性和線膨脹率很大。</p><div
