，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，后來由于PA具有強(qiáng)韌、耐磨、自潤滑、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)動機(jī)燃油泵齒輪、水泵，改性聚酰胺哪家好、高壓密封圈、輸油管等。 [1] 是美國DuPont公司較先開發(fā)用于纖維的樹脂，于1939年實(shí)現(xiàn)工業(yè)化。 20世紀(jì)50年代開始開發(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)藥品性和自潤滑性，且摩擦系數(shù)低，有一定的阻燃性，改性聚酰胺哪家好，易于加工，適于用玻璃纖維和其它填料填充增強(qiáng)改性，改性聚酰胺哪家好，提高性能和擴(kuò)大應(yīng)用范圍。聚酰胺合成方法與普通的線性大分子的合成方法也不同。改性聚酰胺哪家好</p><div

style="text-indent:25px">由于聚酰胺具有無毒、質(zhì)輕、優(yōu)良的機(jī)械強(qiáng)度、耐磨性及較好的耐腐蝕性，因此普遍應(yīng)用于代替銅等金屬在機(jī)械、化工、儀表、汽車等工業(yè)中制造軸承、齒輪、泵葉及其他零件。聚酰胺熔融紡成絲后有很高的強(qiáng)度，主要做合成纖維并可作為醫(yī)用縫線。錦綸在民用上可以混紡或純紡成各種醫(yī)療及針織品。錦綸長絲多用于針織及絲綢工業(yè)，如織單絲襪、彈力絲襪等各種耐磨解釋的錦綸襪，錦綸紗巾，蚊帳，錦綸花邊，彈力錦綸外衣，各種錦綸綢或交織的絲綢品。錦綸短纖維大都用來與羊毛或其它化學(xué)纖維的毛型產(chǎn)品混紡，制成各種耐磨經(jīng)穿的衣料。在工業(yè)上錦綸大量用來制造簾子線、工業(yè)用布、纜繩、傳送帶、帳篷、漁網(wǎng)等。在**上主要用作降落傘及其他***織物。聚酰胺分子鏈上的重復(fù)結(jié)構(gòu)單元是酰胺基的一類聚合物。聚酰胺可制成長纖或短纖。美國杜邦PA6670G30L聚酰胺具備更好的剛性結(jié)構(gòu)，其耐熱性、化學(xué)穩(wěn)定性優(yōu)異，且更易溶于有機(jī)溶劑。</p><div

分子結(jié)構(gòu)中，酰胺基團(tuán)與酰亞胺基團(tuán)連在同一個芳環(huán)上，呈有規(guī)則的排列，使得PAI兼具聚酰胺和聚酰亞胺的特點(diǎn)。PAI 在很好地解決了聚酰亞胺加工成型比較難的問題的同時，又保留了聚酰亞胺原有的優(yōu)異特性，如耐熱性、力學(xué)性能、耐蠕變性、耐輻射性和化學(xué)穩(wěn)定性等。此外，相比于聚酰亞胺，PAI還具備更好的剛性結(jié)構(gòu)，其耐熱性、化學(xué)穩(wěn)定性優(yōu)異，且更易溶于有機(jī)溶劑。PAI是具備更好的剛性結(jié)構(gòu)，其耐熱性、化學(xué)穩(wěn)定性優(yōu)異，且更易溶于有機(jī)溶劑。聚酰胺的吸水率隨單體中碳鏈的增加而減少。</p><div

(2)聚酰胺對于礦物油、動物油、植物油的穩(wěn)定性良好，在汽油中長期浸泡，性質(zhì)不會發(fā)生變化，較大增重不超過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。
