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共聚物熔點低、熱穩(wěn)定性、耐化學(xué)腐蝕性、流動特性、耐水解、耐強堿和熱力氧化降級、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、機械強度、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)固有強度。因填加PTFE（鐵氟龍）纖維而有某些性能改變，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,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,對甲醛共聚物與均聚物標(biāo)準(zhǔn)品級的物性進行一下比較.雖然在短期機械特性方面,有均聚物高于共聚物的傾向,但在長期機械特性方面，共聚物則比均聚物降低的比例小。 pom優(yōu)點1、具高機械強度和剛性 2、比較高的疲勞強度 3、環(huán)境抵抗性、耐有機溶劑性佳 4、耐反覆沖擊性強。蘇州黑色pom賽鋼板哪家便宜</p><p style="text-indent:25px">POM板是一種表面光滑，有光澤的硬而致密的材料，淡黃或白色，可在-40- 100°C溫度范圍內(nèi)長期使用。杭州批發(fā)pom賽鋼板生產(chǎn)廠家</p><p
