鑒別pom聚甲醛板棒的的真假：很多朋友，尤其是采購(gòu)的朋友對(duì)物性了解甚少，很難分辨采購(gòu)的pom原料是否是真品，在此多特瑪工程塑料的推薦2種方便快捷的辦法供各位朋友參考，取一些邊角料用如下方法進(jìn)行實(shí)驗(yàn)：1.燃燒氣味法：如果你手邊有打火機(jī)，請(qǐng)使用打火機(jī)點(diǎn)燃一顆，如果原料燃燒釋放出刺激性的甲醛氣味，則說(shuō)明是聚甲醛。2，化學(xué)實(shí)驗(yàn)法：選取少量樣品放入試管中再加入4ml的濃硫酸加熱到70度持續(xù)10分鐘，觀察顏色，如果出現(xiàn)深紫色表示是聚甲醛。</p><p> 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(hào)：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(dòng)特性、耐水解、耐強(qiáng)堿和熱力氧化降級(jí)、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，稍軟，剛性小，比純的聚甲醛樹(shù)脂更滑。與純POM板比較，該材料潤(rùn)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(wú)蠕動(dòng)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(gè)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(shuō),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(duì)甲醛共聚物與均聚物標(biāo)準(zhǔn)品級(jí)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(zhǎng)期機(jī)械特性方面，共聚物則比均聚物降低的比例小。防靜電POM就是在POM里加入了抗靜電劑，ESD225 POM板就是在POM里加入ESD225這種抗靜電材料加工制成的。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="合肥防靜電pom板棒供應(yīng)商家,pom"

POM塑料俗稱賽鋼，也稱之為聚甲醛，其表面噴漆出現(xiàn)油漆難附著掉漆的現(xiàn)象主要是由于其高結(jié)晶度和高密度，表面極性差，油漆與POM賽鋼基材表面無(wú)法有效形成極性基團(tuán)的牢固結(jié)合，因此在噴涂橡膠漆或塑膠漆等其他油漆時(shí)，易出現(xiàn)油漆脫落的現(xiàn)象，進(jìn)行百格附著力測(cè)試時(shí)無(wú)法達(dá)到附著力要求。</span>
