style="text-indent:25px">聚酰胺簡(jiǎn)稱(PA)的商品名稱叫作尼龍，纖維制品稱為錦綸。聚酰胺塑料是在聚酰胺纖維的基礎(chǔ)上發(fā)展起來(lái)的，目前聚酰胺的主要用途仍為制造纖維(約占70%)。1980年全世界聚酰胺的產(chǎn)顯約為500萬(wàn)噸左右。聚酰胺是一種由含有羧基和氨基的單體，通過(guò)酰胺鍵聚合成的高分子。聚酰胺也可能是自然形成的，比如我們常見的羊毛，絲等，也可能是人工合成的，比如屁龍。聚酰胺的分子式：[NH-R-CO]x或[NH-R-CO-R-CO]x。聚酰胺的結(jié)構(gòu)式，聚酰胺是一種多種無(wú)序結(jié)構(gòu)組成。</p><p style="text-indent:25px">PA66特性:1、具有優(yōu)良的耐磨性、自潤(rùn)滑性，機(jī)械強(qiáng)度較高。但吸水性較大，因而尺寸穩(wěn)定性較差.2、PA66在較高溫度也能保持較強(qiáng)的強(qiáng)度和剛度。PA66在成型后仍然具有吸濕性，其程度主要取決于材料的組成、壁厚以及環(huán)境條件.3、在產(chǎn)品設(shè)計(jì)時(shí)，一定要考慮吸濕性對(duì)幾何穩(wěn)定性的影響。為了提高PA66的機(jī)械特性，經(jīng)常加入各種各樣的改性劑。玻璃就是常見的添加劑，有時(shí)為了提高抗沖擊性還加入合成橡膠，如EPDM和SBR等。PA66的粘性較低，因此流動(dòng)性很好（但不如PA6）。這個(gè)性質(zhì)可以用來(lái)加工很薄的元件。它的粘度對(duì)溫度變化很敏感。4、PA66的收縮率在1%~2%之間，加入玻璃纖維添加劑可以將收縮率降低到0.2%~1%。收縮率在流程方向和與流程方向相垂直方向上的相異是較大的。PA66對(duì)許多溶劑具有抗溶性，但對(duì)酸和其它一些氯化劑的抵抗力較弱。聚酰胺在電子顯微鏡下可觀察到絲狀的原纖組織，錦綸66的原纖寬約10-15nm。</p><div

style="text-indent:25px">聚酰胺的產(chǎn)品：增強(qiáng)PA。在PA中加入30%的玻璃纖維，PA的力學(xué)性能、尺寸穩(wěn)定性、耐熱性、耐老化性能有明顯提高，耐疲勞強(qiáng)度是未增強(qiáng)的2.5倍。玻璃纖維增強(qiáng)PA的成型工藝與未增強(qiáng)時(shí)大致相同，但因流動(dòng)較增強(qiáng)前差，所以注射壓力和注射速度要適當(dāng)提高，機(jī)筒溫度提高10-40℃。由于玻纖在注塑過(guò)程中會(huì)沿流動(dòng)方向取向，引起力學(xué)性能和收縮率在取向方向上增強(qiáng)，導(dǎo)致制品變形翹曲，因此，模具設(shè)計(jì)時(shí)，澆口的位置、形狀要合理，工藝上可以提高模具的溫度，制品取出后放入熱水中讓其緩慢冷卻。另外，加入玻纖的比例越大，其對(duì)注塑機(jī)的塑化元件的磨損越大，較好是采用雙金屬螺桿、機(jī)筒。PA66聚己二酰己二胺，俗稱尼龍雙6。美國(guó)首諾PA66R533H</p><p style="text-indent:25px">聚酰胺的阻燃改性具有非常重要的意義。美國(guó)首諾PA66R533H</p><p style="text-indent:25px">聚酰胺用途：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，比棉花耐磨性高10倍，比羊毛高20倍，在混紡織物中稍加入一些聚酰胺纖維，可較大提高其耐磨性；當(dāng)拉伸至3-6%時(shí)，彈性回復(fù)率可達(dá)100%；能經(jīng)受上萬(wàn)次折撓而不斷裂。聚酰胺纖維的強(qiáng)度比棉花高1-2倍、比羊毛高4-5倍，是粘膠纖維的3倍。但聚酰胺纖維的耐熱性和耐光性較差，保持性也不佳，做成的衣服不如滌綸挺括。另外，用于衣著的錦綸-66和錦綸-6都存在吸濕性和染色性差的缺點(diǎn)，為此開發(fā)了聚酰胺纖維的新品種——錦綸-3和錦綸-4的新型聚酰胺纖維，具有質(zhì)輕、防皺性優(yōu)良、透氣性好以及良好的耐久性、染色性和熱定型等特點(diǎn)，因此被認(rèn)為是很有發(fā)展前途的。美國(guó)首諾PA66R533H</p></p><br
