3.聚酰胺抗靜電性能不好。聚酰胺的電性能，由于聚酰胺是親水性的，很難得到一定干燥的制品，而它的電性能又隨著含水較的變化而變化，所以在通常情況下不用它作電絕緣材料。 4.聚酰胺耐熱性比較差。 5.聚酰胺的吸水性和線膨脹率很大，特別是尼龍-6和尼龍-66較為明顯，在大氣中的平衡吸水率可達(dá)3.5%，常溫下浸入水中24小時(shí)，其飽和吸水率可達(dá)10.7%。吸水的結(jié)果造成體積膨脹，當(dāng)吸水率為3.5%時(shí)，線膨脹率為0.65%,當(dāng)吸水率為線膨脹率為2.3%,尺寸穩(wěn)定性很差。吸水后制品的抗拉強(qiáng)度有明顯的降低，減量可達(dá)30?50%，但韌性更好，沖擊強(qiáng)度可提高3?4倍。一定干燥的聚酰胺硬而脆,韌性和延伸率都很差，無法使用，但它在空氣中會(huì)自動(dòng)吸水，隨著吸水量的枏加，其綜合性能也有改善。聚酰胺的吸水率隨單體中碳鏈的增加而減少。</p><p

style="text-indent:25px">聚酰胺(PA，俗稱尼龍)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。聚酰胺主鏈上含有許多重復(fù)的酰胺基，用作塑料時(shí)稱尼龍，用作合成纖維時(shí)我們稱為錦綸，聚酰胺可由二元胺和二元酸制取，也可以用ω-氨基酸或環(huán)內(nèi)酰胺來合成。根據(jù)二元胺和二元酸或氨基酸中含有碳原子數(shù)的不同，可制得多種不同的聚酰胺，聚酰胺品種多達(dá)幾十種，其中以聚酰胺-6、聚酰胺-66和聚酰胺-610的應(yīng)用較普遍。聚酰胺以避免熔體與空氣接觸及切片再熔時(shí)的氧化降解。層析用聚酰胺銷售</p><p style="text-indent:25px">聚酰胺樹脂配制的油墨有光澤性，粘結(jié)性能好，醇稀釋性優(yōu)良，膠凝性低，快干，氣味小。上海層析PA66價(jià)格</p><p style="text-indent:25px">常用的聚酰胺纖維可分為兩大類。一類是由二胺和二酸縮聚而得的聚己二酸己二胺，其長鏈分子的化學(xué)結(jié)構(gòu)式為：H-[HN(CH2)XNHCO(CH2)YCO]-OH，這類錦綸的相對(duì)分子量一般為17000-23000。另一類是由己內(nèi)酰胺縮聚或開環(huán)聚合得到的，其長鏈分子的化學(xué)結(jié)構(gòu)式為：H-[NH(CH2)XCO]-OH。聚酰胺纖維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)腐蝕性和自潤滑性，且摩擦系數(shù)低，有一定的阻燃性，易于加工，易于使用玻璃纖維和其它填料填充改性。聚酰胺主要用于合成纖維，其較突出的優(yōu)點(diǎn)是耐磨性高于其他所有纖維。上海層析PA66價(jià)格</p><p
