怎樣區(qū)分POM板棒是均聚還是共聚？POM棒/板一般有以下幾種型號：POM-C/H（黑色、白色）：分別表示POM共聚物和POM均聚物，POM共聚物熔點(diǎn)低、熱穩(wěn)定性、耐化學(xué)腐蝕性、流動特性、耐水解、耐強(qiáng)堿和熱力氧化降級、加工性優(yōu)于均聚甲醛。POM均聚物結(jié)晶度高、搞蠕變性、熱膨脹率更低、耐磨性、機(jī)械強(qiáng)度、剛性、熱變形溫度等比共聚甲醛好。（目前市面上POM半成品普遍使用POM-C共聚物）POM-H+PTFE（深棕色）：POM+TF棒/板是用杜邦POM（DELRIN）原料加PTFE（鐵氟龍）纖維擠出而成。它保留了POM-H的大多數(shù)固有強(qiáng)度。因填加PTFE（鐵氟龍）纖維而有某些性能改變，鎮(zhèn)江黑色pom板價格，稍軟，剛性小，比純的聚甲醛樹脂更滑。與純POM板比較，該材料潤滑更好。用POM-H+PTFE制造的軸承摩擦系數(shù)中等，耐磨，并且基本無蠕動現(xiàn)象。由于均聚物里共聚成分的插入，鎮(zhèn)江黑色pom板價格,除了熱穩(wěn)定性外,其它性質(zhì)也發(fā)生了一些變化.一般,共聚成分是多一個碳元素的氧化乙烯基-CH2CH2O-.雖然因引入的比例而異,但是可以說,共聚甲醛的性質(zhì)是在甲醛均聚物中加入氧化乙烯聚合物而共同形成的.下面，鎮(zhèn)江黑色pom板價格,對甲醛共聚物與均聚物標(biāo)準(zhǔn)品級的物性進(jìn)行一下比較.雖然在短期機(jī)械特性方面,有均聚物高于共聚物的傾向,但在長期機(jī)械特性方面，共聚物則比均聚物降低的比例小。 POM天生表面比尼龍光滑所以其耐磨性能比尼龍要好些,而其他一些性能比如耐熱,抗擊,耐候,機(jī)械等性能相當(dāng)。鎮(zhèn)江黑色pom板價格</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="font-size:14px;font-family:"">其中，聚甲醛（POM）是一種性能優(yōu)良的工程塑料，在國外有“賽鋼”、“奪鋼”、“超鋼”之稱。POM具有類似金屬的硬度、強(qiáng)度和鋼性，在很寬的溫度和濕度范圍內(nèi)都具有很好的自潤滑性、良好的耐疲勞性，并富于彈性，此外它還有較好的耐化學(xué)品性。POM以低于其他許多工程塑料的成本，正在替代一些傳統(tǒng)上被金屬所占領(lǐng)的市場，如替代鋅、黃銅、鋁和鋼制作許多部件，自問世以來，POM已經(jīng)廣泛應(yīng)用于電子電氣、機(jī)械、儀表、日用輕工、汽車、建材、農(nóng)業(yè)等領(lǐng)域。</span><span style="font-size:14px;font-family:"">它不僅可減輕零部件約40%的重量，而且還可以使采購成本降低20%-30%左右，因此近年來在汽車中的用量迅速上升。而共聚甲醛（POM）由于其出色的剛度、耐磨性、抗腐蝕性、降低成本等特性成為了汽車制造商的“新寵”。將來，POM材料還將進(jìn)一步改良，逐漸替代鋁、鋼、銅等材料在汽車中的應(yīng)用，在汽車輕量化和降本方面作出更大的貢獻(xiàn)。</span> </p> </p><p><span style="font-size:14px;font-family:";"> POM板棒改性的意義。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)，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，為了更好地適應(yīng)高速、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。</span>
