型號不同硬度也是不一樣的，POM材料各個型號的硬度相差也不是很大，東莞耐高溫pom棒材采購?？傮w來說POM的硬度是比較高的，洛氏硬度達到D80-85Z這樣的，在工程塑料里面是屬于高硬度的材料的，東莞耐高溫pom棒材采購，就硬度方面跟鋼材有的一比，在其他的一些加工性能上，POM的也是不錯的，做一些零配件，軸承，齒輪等，也是不錯的?，F(xiàn)在工程塑料是一個新興行業(yè)，好多能代替鋼材，具有金屬材料沒有的性能，像絕緣，耐磨，耐酸堿等。 POM均聚物結晶度高、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。東莞耐高溫pom棒材采購</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="東莞耐高溫pom棒材采購,pom"

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準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。東莞批發(fā)pom棒生產(chǎn)廠家POM-C/H（黑色、白色）：分別指的是POM共聚物和POM均聚物。</p><div

聚甲醛pom有毒嗎？聚甲醛（POM）在注塑過程中會產(chǎn)生少量甲醛氣體，在正常生產(chǎn)條件下不會造成嚴重問題。然而，聚甲醛在220℃的溫度下經(jīng)歷熱降解，特別是當其長時間暴露于高溫時，并且容易產(chǎn)生大量的甲醛氣體。這種氣體有刺激性，可能對眼睛和喉嚨造成傷害。過量吸入會引起頭暈和惡心。在生產(chǎn)中，只要注意控制注塑機注射管的溫度，在短暫停機期間反復清空材料管，并且在關機期間必須關閉材料管的加熱以避免燃燒的材料和氣體。一旦排出氣體，撤離人員并保持通風。本公司專業(yè)從事耐高溫POM、增韌POM、增強POM、耐候POM、擠出POM、耐磨POM、自潤滑POM、抗靜電POM等原材料板材及棒材的銷售，采購請致電蘇州多特瑪工程塑料有限公司，聯(lián)系方式見此頁面左邊或右邊。</p><p
