POM在成形加工過程中極易結(jié)晶，生成尺寸較大的球晶，當(dāng)材料受到?jīng)_擊時，這些尺寸較大的球晶容易形成應(yīng)力集中點(diǎn)，蘇州高分子POM生產(chǎn)廠家，造成材料的破壞，所以POM缺口敏感性大，缺口沖擊強(qiáng)度低，成型收縮率高, 制品易產(chǎn)生內(nèi)應(yīng)力, 難于緊密成型。這極大地限制了POM的使用范圍，在某些方面不能滿足工業(yè)要求，因此，蘇州高分子POM生產(chǎn)廠家，為了更好地適應(yīng)高速，蘇州高分子POM生產(chǎn)廠家、高壓、高溫、高負(fù)荷等苛刻的工作環(huán)境，進(jìn)一步擴(kuò)大POM的應(yīng)用范圍，需進(jìn)一步提高聚甲醛的沖擊韌性，耐熱和耐摩擦等性能。聚甲醛全名聚甲醛樹脂，簡稱聚甲醛，熱塑性結(jié)晶聚合物。被譽(yù)為“超鋼”或者“賽鋼”。蘇州高分子POM生產(chǎn)廠家</p><div

style="text-indent:25px">聚甲醛阻燃改性：純聚甲醛具有易燃的性質(zhì)，屬于極易燃燒的塑料。阻燃劑的添加是重要的改性手段。直接添加阻燃劑很難使聚甲醛具有優(yōu)良的阻燃性能，復(fù)合阻燃體系可以增加聚甲醛的相容性。目前業(yè)內(nèi)關(guān)于聚甲醛阻燃研究主要集中于無鹵膨脹型阻燃體系。聚甲醛常用的膨脹體系一般有：阻燃劑、成炭劑、甲醛吸收劑等三個部分。其經(jīng)典構(gòu)成有聚磷酸胺、**和三聚氰胺，它們都具有良好的阻燃性，而且符合當(dāng)前對阻燃劑的少煙、低毒的要求，可以同時提高聚甲醛的阻燃性、熱穩(wěn)定性和光穩(wěn)定性。蘇州高分子POM生產(chǎn)廠家聚甲醛與聚乙烯相比，聚甲醛的碳氧鍵短，內(nèi)聚能密度高，密度大。</p><div

style="text-indent:25px">聚甲醛簡介：聚甲醛（POM）又名縮醛樹脂、聚氧亞甲基，按分子鏈結(jié)構(gòu)的不同，分為均聚甲醛和共聚甲醛。聚甲醛是一種綜合性能優(yōu)良的熱塑性工程塑料，為五大工程塑料之一。聚甲醛質(zhì)輕，比強(qiáng)度、比剛度與金屬類似，是工程塑料中力學(xué)性能zui接近金屬材料的一種工程塑料，被稱為“塑料中的金屬”，也被譽(yù)為“超鋼”、“賽鋼”、“奪鋼”等。聚甲醛為線性結(jié)構(gòu)聚合物，分子結(jié)構(gòu)規(guī)整性高，機(jī)械性能十分優(yōu)異，具有良好的自潤滑性、耐疲勞性、抗蠕變性、吸水性小、耐磨性、耐腐蝕性等優(yōu)良性能，同時還有較好的耐化學(xué)品性、耐電弧性、著色性等。聚甲醛在很多場合是可替代黃銅、鋅、鋁和鋼等金屬制作的部件，普遍應(yīng)用于工業(yè)機(jī)械、汽車、電子電器、日用品、管道及配件、精密儀器和建材等領(lǐng)域。聚甲醛添加硅油、礦物油、油脂等潤滑油及潤滑脂類。</p><div

style="text-indent:25px">生產(chǎn)均聚甲醛的工藝：均聚甲醛是三聚甲醛的均聚體，在抗疲勞強(qiáng)度和延展強(qiáng)度方面都有著非常出色的表現(xiàn)，但是對其進(jìn)行加工時有著一定的難度，而且在進(jìn)行加工時其加工溫度的范圍是比較小的，在成型時熱分解、熱穩(wěn)定性、熱劣化特性、耐酸堿腐蝕性以及耐熱水性等方面均聚甲醛是不如共聚甲醛的。但是均聚甲醛的結(jié)晶度是非常高的，在彈性率、強(qiáng)度以及表征物理耐熱性的復(fù)合彎曲溫度方面要略好于共聚甲醛。同時聚甲醛具備著十分較好的剛性，其拉伸強(qiáng)度zui高可達(dá)到68.9MPa，而且均聚甲醛的摩擦因素比較小、耐磨性比較好，但是均聚甲醛在耐酸和穩(wěn)定性方面是比較差的。聚甲醛結(jié)晶度高，機(jī)械強(qiáng)度、剛性、熱變形溫度等比共聚甲醛好。蘇州高分子POM生產(chǎn)廠家</p><p
