Leona 1300G Asahi Kasei特性：

PA66塑料(liao)(liao)(liao)在(zai)聚酰胺材(cai)料(liao)(liao)(liao)中有較高的(de)(de)(de)(de)熔(rong)(rong)(rong)(rong)點(dian)。PA66塑料(liao)(liao)(liao)在(zai)成型后仍然(ran)具有吸濕性，PA66塑料(liao)(liao)(liao)的(de)(de)(de)(de)粘性較低， PA66塑料(liao)(liao)(liao)熱性質熔(rong)(rong)(rong)(rong)點(dian)即(ji)結晶(jing)熔(rong)(rong)(rong)(rong)解時的(de)(de)(de)(de)溫(wen)(wen)度，對結晶(jing)性高分(fen)子PA66塑料(liao)(liao)(liao)，顯示清晰的(de)(de)(de)(de)熔(rong)(rong)(rong)(rong)點(dian)，根(gen)據(ju)采(cai)用(yong)的(de)(de)(de)(de)測試方(fang)法，熔(rong)(rong)(rong)(rong)點(dian)在(zai)259~267℃的(de)(de)(de)(de)范(fan)圍(wei)內波動。通(tong)常采(cai)用(yong)差熱分(fen)析法測出(chu)的(de)(de)(de)(de)PA66塑料(liao)(liao)(liao)的(de)(de)(de)(de)熔(rong)(rong)(rong)(rong)點(dian)為(wei)(wei)264℃。如(ru)果(guo)將體積(ji)膨(peng)脹系數顯示極大值(zhi)的(de)(de)(de)(de)溫(wen)(wen)度當(dang)作(zuo)熔(rong)(rong)(rong)(rong)點(dian)，則尼龍-66的(de)(de)(de)(de)熔(rong)(rong)(rong)(rong)點(dian)溫(wen)(wen)度范(fan)圍(wei)為(wei)(wei)246~263℃。接近理論熔(rong)(rong)(rong)(rong)解溫(wen)(wen)度259℃。 PA66塑料(liao)(liao)(liao)的(de)(de)(de)(de)注塑特性干(gan)(gan)燥(zao)(zao)(zao)處理：如(ru)果(guo)加工前(qian)材(cai)料(liao)(liao)(liao)是密封的(de)(de)(de)(de)，那么就沒有必要干(gan)(gan)燥(zao)(zao)(zao)。然(ran)而，如(ru)果(guo)儲存容器(qi)被打開，那么建議在(zai)85C的(de)(de)(de)(de)熱空氣中干(gan)(gan)燥(zao)(zao)(zao)處理。如(ru)果(guo)濕度大于0.2%，還需要進行105C，12小(xiao)時的(de)(de)(de)(de)真空干(gan)(gan)燥(zao)(zao)(zao)。

Leona 1300G Asahi Kasei用途：

PA66為半(ban)透明(ming)或不透明(ming)乳(ru)白(bai)色(se)結晶形(xing)聚(ju)合物，具有可塑(su)性。外觀白(bai)包或帶黃色(se)顆粒狀(zhuang)，廣泛用(yong)(yong)于制造機械(xie)、汽車、化學與電氣(qi)裝置的零件，如齒輪、滾子(zi)、滑(hua)輪、輥軸、泵體(ti)中葉輪、風扇葉片、高壓密封(feng)圍、閥座、墊(dian)片、襯套、各種把手、支(zhi)撐架、電線包層(ceng)等(deng)。亦可制成薄膜用(yong)(yong)作包裝材料。此外，還可用(yong)(yong)于制作醫療(liao)器械(xie)、體(ti)育(yu)用(yong)(yong)品、日(ri)用(yong)(yong)品等(deng)。

PA66廣泛應用于(yu)汽車(che)工(gong)業、儀器殼(ke)體以及(ji)其它(ta)需(xu)要(yao)有(you)抗沖擊(ji)性(xing)(xing)和高(gao)(gao)(gao)強(qiang)度要(yao)求的(de)產品(pin)。PA66在(zai)(zai)聚酰胺材料(liao)中有(you)較(jiao)高(gao)(gao)(gao)的(de)熔點。它(ta)是(shi)一(yi)種半晶(jing)體-晶(jing)體材料(liao)。PA66在(zai)(zai)較(jiao)高(gao)(gao)(gao)溫度也能保(bao)持較(jiao)強(qiang)的(de)強(qiang)度和剛度。PA66在(zai)(zai)成型(xing)后仍然具有(you)吸(xi)濕(shi)性(xing)(xing)，其程(cheng)度主要(yao)取(qu)決于(yu)材料(liao)的(de)組(zu)成、壁厚以及(ji)環(huan)境條件。在(zai)(zai)產品(pin)設計時，一(yi)定(ding)要(yao)考慮吸(xi)濕(shi)性(xing)(xing)對(dui)幾何(he)穩定(ding)性(xing)(xing)的(de)影(ying)響(xiang)。為(wei)(wei)了(le)提高(gao)(gao)(gao)PA66的(de)機械特性(xing)(xing)，經常(chang)加入(ru)各種各樣的(de)改(gai)性(xing)(xing)劑。玻璃(li)就(jiu)是(shi)較(jiao)常(chang)見的(de)添加劑，有(you)時為(wei)(wei)了(le)提高(gao)(gao)(gao)抗沖擊(ji)性(xing)(xing)還加入(ru)合成橡(xiang)膠，如EPDM和SBR等(deng)。
