　　PA（尼龍）很高(gao)的(de)機(ji)械(xie)強(qiang)度(du)，軟(ruan)化點高(gao)，耐(nai)熱，摩(mo)擦(ca)系數低，抗磨損，自(zi)潤滑性(xing)(xing)(xing)等優異(yi)性(xing)(xing)(xing)能，已成(cheng)為目前國內外廣泛應(ying)用(yong)的(de)熱塑性(xing)(xing)(xing)工程塑料之一。 但在(zai)實際應(ying)用(yong)，不(bu)同(tong)的(de)使(shi)用(yong)條(tiao)件(jian)或(huo)環境下，對尼龍的(de)性(xing)(xing)(xing)能要(yao)求又各有不(bu)同(tong)。雖然(ran)開發(fa)的(de)改(gai)性(xing)(xing)(xing)尼龍在(zai)不(bu)斷進(jin)步(bu)中，但是這些(xie)產(chan)(chan)品(pin)(pin)仍(reng)然(ran)會面臨各種問(wen)題(ti)。 目前，市面上(shang)的(de)增(zeng)韌改(gai)性(xing)(xing)(xing)尼龍會存在(zai)材料光澤度(du)差，流(liu)動性(xing)(xing)(xing)不(bu)足等問(wen)題(ti)，嚴重影響制品(pin)(pin)表(biao)現，導(dao)致(zhi)產(chan)(chan)品(pin)(pin)不(bu)良率(lv)高(gao)居不(bu)下；甚至某些(xie)產(chan)(chan)品(pin)(pin)在(zai)長時(shi)間(jian)的(de)高(gao)溫的(de)情況下還會存在(zai)熱氧老化問(wen)題(ti)。這些(xie)種種問(wen)題(ti)都使(shi)得(de)產(chan)(chan)品(pin)(pin)的(de)質量與其(qi)機(ji)械(xie)性(xing)(xing)(xing)能下降。 為什么(me)尼龍要(yao)增(zeng)強(qiang)增(zeng)韌？ 尼龍PA的(de)尺寸(cun)穩定性(xing)(xing)(xing)差，耐(nai)光性(xing)(xing)(xing)較差。在(zai)長期偏高(gao)溫環境下會與空氣中的(de)氧發(fa)生氧化作用(yong)，開始時(shi)顏色變褐。且尼龍在(zai)低溫的(de)情況下，飽(bao)和吸(xi)水率(lv)降低會導(dao)致(zhi)尼龍脆(cui)性(xing)(xing)(xing)大，易(yi)變脆(cui)斷裂，當粘(zhan)接(jie)部位承受外力(li)時(shi)很容易(yi)產(chan)(chan)生裂紋，繼面破碎開裂，不(bu)耐(nai)疲勞。

      鑫(xin)昇可(ke)以(yi)解(jie)決(jue)這一(yi)問題。增(zeng)(zeng)(zeng)(zeng)韌(ren)(ren)耐(nai)(nai)寒(han)(han)，添加了(le)(le)功能(neng)(neng)(neng)穩定(ding)助劑，在(zai)(zai)(zai)低(di)(di)溫狀態下(xia)也可(ke)以(yi)使尼(ni)(ni)龍(long)的(de)(de)(de)含水率保(bao)持穩定(ding)。可(ke)以(yi)使低(di)(di)溫狀況(kuang)下(xia)的(de)(de)(de)尼(ni)(ni)龍(long)制品保(bao)持良(liang)好的(de)(de)(de)物性(xing)(xing)(xing)(xing)(xing)(xing)(xing)，無脆斷、無開(kai)裂，穩定(ding)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)好。 一(yi)般來說，尼(ni)(ni)龍(long)增(zeng)(zeng)(zeng)(zeng)韌(ren)(ren)后(hou)韌(ren)(ren)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)提(ti)(ti)(ti)高(gao)，而(er)(er)剛(gang)(gang)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)下(xia)降(jiang)；而(er)(er)增(zeng)(zeng)(zeng)(zeng)強(qiang)(qiang)后(hou)剛(gang)(gang)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)提(ti)(ti)(ti)高(gao)，而(er)(er)韌(ren)(ren)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)會(hui)(hui)下(xia)降(jiang)。（原因：1.改性(xing)(xing)(xing)(xing)(xing)(xing)(xing)尼(ni)(ni)龍(long)強(qiang)(qiang)度(du)(du)(du)(du)(du)(du)(du)，主要錨點就(jiu)是剛(gang)(gang)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)，它(ta)的(de)(de)(de)拉伸強(qiang)(qiang)度(du)(du)(du)(du)(du)(du)(du)、彎(wan)曲(qu)(qu)強(qiang)(qiang)度(du)(du)(du)(du)(du)(du)(du)、簡支(zhi)梁(liang)沖擊(ji)強(qiang)(qiang)度(du)(du)(du)(du)(du)(du)(du)等性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)都大(da)(da)幅度(du)(du)(du)(du)(du)(du)(du)增(zeng)(zeng)(zeng)(zeng)加，因為有(you)(you)(you)玻璃纖(xian)(xian)維的(de)(de)(de)加入(ru)，它(ta)的(de)(de)(de)耐(nai)(nai)溫大(da)(da)幅度(du)(du)(du)(du)(du)(du)(du)提(ti)(ti)(ti)升，但是它(ta)的(de)(de)(de)韌(ren)(ren)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)會(hui)(hui)大(da)(da)幅降(jiang)低(di)(di)，因此(ci)它(ta)的(de)(de)(de)脆性(xing)(xing)(xing)(xing)(xing)(xing)(xing)顯露出(chu)(chu)來了(le)(le)。 2.改性(xing)(xing)(xing)(xing)(xing)(xing)(xing)尼(ni)(ni)龍(long)韌(ren)(ren)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)，主要就(jiu)是柔性(xing)(xing)(xing)(xing)(xing)(xing)(xing)，它(ta)的(de)(de)(de)簡支(zhi)梁(liang)沖擊(ji)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)大(da)(da)幅度(du)(du)(du)(du)(du)(du)(du)提(ti)(ti)(ti)升，甚至可(ke)以(yi)在(zai)(zai)(zai)很大(da)(da)沖擊(ji)力下(xia)表現(xian)很好，但是它(ta)的(de)(de)(de)強(qiang)(qiang)度(du)(du)(du)(du)(du)(du)(du)大(da)(da)幅度(du)(du)(du)(du)(du)(du)(du)降(jiang)低(di)(di)，所以(yi)剛(gang)(gang)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)差，拉伸強(qiang)(qiang)度(du)(du)(du)(du)(du)(du)(du)、彎(wan)曲(qu)(qu)強(qiang)(qiang)度(du)(du)(du)(du)(du)(du)(du)都下(xia)降(jiang)。）所以(yi)具有(you)(you)(you)增(zeng)(zeng)(zeng)(zeng)強(qiang)(qiang)增(zeng)(zeng)(zeng)(zeng)韌(ren)(ren)特性(xing)(xing)(xing)(xing)(xing)(xing)(xing)是十(shi)分(fen)重要的(de)(de)(de)，他(ta)可(ke)以(yi)提(ti)(ti)(ti)高(gao)尼(ni)(ni)龍(long)的(de)(de)(de)機(ji)械(xie)(xie)強(qiang)(qiang)度(du)(du)(du)(du)(du)(du)(du)，提(ti)(ti)(ti)高(gao)抗沖強(qiang)(qiang)度(du)(du)(du)(du)(du)(du)(du)；使材(cai)(cai)料的(de)(de)(de)拉伸強(qiang)(qiang)度(du)(du)(du)(du)(du)(du)(du)、彎(wan)曲(qu)(qu)強(qiang)(qiang)度(du)(du)(du)(du)(du)(du)(du)有(you)(you)(you)大(da)(da)幅度(du)(du)(du)(du)(du)(du)(du)的(de)(de)(de)提(ti)(ti)(ti)高(gao)。 現(xian)在(zai)(zai)(zai)市面(mian)上(shang)有(you)(you)(you)一(yi)些不良(liang)貨商(shang)，為了(le)(le)降(jiang)低(di)(di)成(cheng)本提(ti)(ti)(ti)高(gao)利潤，采用添加不良(liang)填充料，雖可(ke)以(yi)達(da)到增(zeng)(zeng)(zeng)(zeng)韌(ren)(ren)改性(xing)(xing)(xing)(xing)(xing)(xing)(xing)的(de)(de)(de)目的(de)(de)(de)，但卻損害了(le)(le)材(cai)(cai)料的(de)(de)(de)剛(gang)(gang)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)，并且會(hui)(hui)使材(cai)(cai)料的(de)(de)(de)加工性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)和耐(nai)(nai)熱性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)降(jiang)低(di)(di)。 鑫(xin)昇不會(hui)(hui)以(yi)犧(xi)牲某種(zhong)力學性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)為代價，使得(de)改性(xing)(xing)(xing)(xing)(xing)(xing)(xing)塑(su)料的(de)(de)(de)力學性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)隨填料填充量的(de)(de)(de)增(zeng)(zeng)(zeng)(zeng)加而(er)(er)下(xia)降(jiang)。
