，它是大分子主鏈重復(fù)單元中含有酰胺基團(tuán)的高聚物的總稱。聚酰胺可由內(nèi)酸胺開(kāi)環(huán)聚合制得，也可由二元胺與二元酸縮聚等得到的。聚酰胺(PA)是指主鏈節(jié)含有極性酰胺基團(tuán)(-CO-NH一)的高聚物。較初用作制造纖維的原料，后來(lái)由于PA具有強(qiáng)韌、耐磨、自潤(rùn)滑、使用溫度范圍寬成為目前工業(yè)中應(yīng)用普遍的一種工程塑料。PA普遍用來(lái)代替銅及其他等優(yōu)點(diǎn)，有色金屬制作機(jī)械、化工、電器零件，如柴油發(fā)動(dòng)機(jī)燃油泵齒輪、水泵、高壓密封圈、輸油管等。 [1] 是美國(guó)DuPont公司較先開(kāi)發(fā)用于纖維的樹(shù)脂，于1939年實(shí)現(xiàn)工業(yè)化。 20世紀(jì)50年代開(kāi)始開(kāi)發(fā)和生產(chǎn)注塑制品，以取代金屬滿足下游工業(yè)制品輕量化、降低成本的要求。PA具有良好的綜合性能，包括力學(xué)性能、耐熱性、耐磨損性、耐化學(xué)藥品性和自潤(rùn)滑性，且摩擦系數(shù)低，有一定的阻燃性，易于加工，適于用玻璃纖維和其它填料填充增強(qiáng)改性，提高性能和擴(kuò)大應(yīng)用范圍。</p><p style="text-indent:25px">聚酯纖維具有許多優(yōu)良的紡織性能和服用性能，用途普遍，可以純紡織造，也可與棉、毛、絲、麻等天然纖維和其他化學(xué)纖維混紡交織，制成花色繁多、堅(jiān)牢挺括、易洗易干、免燙和洗可穿性能良好的仿毛、仿棉、仿絲、仿麻織物。滌綸織物適用于男女襯衫、外衣、兒童衣著、室內(nèi)裝飾織物和地毯等。由于滌綸具有良好的彈性和蓬松性，也可用作絮棉。在工業(yè)上**度滌綸可用作輪胎簾子線、運(yùn)輸帶、消防水管、纜繩、漁網(wǎng)等，也可用作電絕緣材料、耐酸過(guò)濾布和造紙毛毯等。用滌綸制作無(wú)紡織布可用于室內(nèi)裝飾物、地毯底布、醫(yī)藥工業(yè)用布、絮絨、襯里等。聚酰胺樹(shù)脂具有較好的耐藥品性,能抵抗酸堿和植物油、礦物油等。</p><div

杜邦公司有名化學(xué)家卡羅瑟斯和他的科研小組發(fā)明的。尼龍系列是較重要的工程塑料。該產(chǎn)品應(yīng)用普遍，幾乎覆蓋每一個(gè)領(lǐng)域，是五大工程塑料中應(yīng)用較廣的品種。澆鑄尼龍板又稱MC 尼龍：英文名稱 Monomer casting nylon ，中文稱單體澆鑄尼龍。“以塑代鋼、性能厲害”，用途極其普遍。它具有重量輕、強(qiáng)度高、自潤(rùn)滑、耐磨、防腐，絕緣等多種獨(dú)特性能。是應(yīng)用普遍的工程塑料，幾乎遍布所有的工業(yè)領(lǐng)域。目前市面上常用的澆鑄尼龍板主要有以下幾種：　1：MC 尼龍（象牙白）：未改性澆鑄尼龍6的特性與尼龍66極為接近，其綜合性能好，強(qiáng)度，剛度和硬度高，抗蠕變、耐磨，耐熱老化，機(jī)加工性能好等。聚酰胺耐化學(xué)腐蝕性和自潤(rùn)滑性，且摩擦系數(shù)低，有一定的阻燃性。蘇州水性聚酰胺價(jià)格</p><p

(2)聚酰胺對(duì)于礦物油、動(dòng)物油、植物油的穩(wěn)定性良好，在汽油中長(zhǎng)期浸泡，性質(zhì)不會(huì)發(fā)生變化，較大增重不超過(guò)2%，但耐氯甲烷稍差。（3)聚酰胺的綜合的機(jī)械性能較好，抗張強(qiáng)度在600?700公斤/平方厘米之間，抗沖擊値大部分為100公斤米/平方厘米(無(wú)缺口），只有聚酰胺-9較髙，可達(dá)250?300公斤?厘米/平方厘米,聚酰胺的蠕變值都比較大。 (4）聚酰胺的熔點(diǎn)不高，一般在140?280攝氏度之間，聚酰胺長(zhǎng)期使用溫度一般不超過(guò)80攝氏度，短期使用溫度雖可達(dá)120攝氏度，但會(huì)使制品顏色變深. (6)聚酰胺人低溫性能好，在低溫下，強(qiáng)度降低很少。 (7)聚酰胺有自潤(rùn)滑性能，耐磨性好。 (8)聚酰胺有吸音性。 (9）聚酰胺加工性能良好，幷可切削、鉆孔。 (10）聚酰胺制品無(wú)嗅、無(wú)味、無(wú)毒、不會(huì)霉?fàn)€。蘇州苯溶聚酰胺哪家好</p><p
