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(dāng)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(fù)清空材料管，并且在關(guān)機期間必須關(guān)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(fēng)。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。寧波耐高溫pom板材采購pom一般是指聚甲醛塑料，俗稱賽鋼，為結(jié)晶性熱可塑性塑料，具dao明顯熔點65~175℃，性質(zhì)接近金屬。</p><div

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。

style="text-indent:25px">日前從中國橡塑工業(yè)協(xié)會第七屆會員象征大會上獲悉，最近4年間，我國橡膠行業(yè)通過加大品牌培育，積極推進新產(chǎn)品、新工藝、新設(shè)備的開發(fā)應(yīng)用，使國產(chǎn)橡膠制品在市場上的競爭力不斷增強。未來5年，中國橡膠業(yè)要力爭通過努力，躋身強者之列。由于國際化工巨頭接連遭受不可抗力、摩擦，國內(nèi)環(huán)保趨嚴、廢塑料進口禁止，導(dǎo)致原材料成本大幅上升，出口放緩，同時受“限塑”新政出臺、家電/汽車行業(yè)產(chǎn)銷增速下滑等因素影響，國POM板
