style="text-indent:25px">用途：聚甲醛（POM）是一種性能優(yōu)良的工程塑料，在國外有“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)普遍應(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。在很多新領(lǐng)域的應(yīng)用，如醫(yī)療技術(shù)、運(yùn)動(dòng)器械等方面，POM也表現(xiàn)出較好的增長態(tài)勢。無錫高流動(dòng)性POM報(bào)價(jià)聚甲醛聚合物在關(guān)機(jī)前應(yīng)清洗干凈，以免在啟動(dòng)過程中過熱。</p><div

聚甲醛的分子是一種沒有側(cè)鏈的高密度、高結(jié)晶性的線型聚合物。由于C-O鍵的鍵長小于C-C鍵，因此聚甲醛鏈軸方向的填充密度大。與聚乙烯相比，聚甲醛的碳氧鍵短，內(nèi)聚能密度高，密度大。按其分子鏈中化學(xué)結(jié)構(gòu)的不同，可分為均聚甲醛和共聚甲醛兩種。兩者的重要區(qū)別是：均聚甲醛密度、結(jié)晶度、熔點(diǎn)都高，但熱穩(wěn)定性差，加工溫度范圍窄（約10℃），對(duì)酸堿穩(wěn)定性略低；而共聚甲醛密度、結(jié)晶度、熔點(diǎn)、強(qiáng)度都較低，但熱穩(wěn)定性好，不易分解，加工溫度范圍寬（約50℃），對(duì)酸堿穩(wěn)定性較好。是具有優(yōu)異的綜合性能的工程塑料。有良好的物理、機(jī)械和化學(xué)性能，尤其是有優(yōu)異的耐摩擦性能。俗稱賽鋼或奪鋼，為第三大通用塑料。適于制作減磨耐磨零件,傳動(dòng)零件,以及化工,儀表等零件。</p><p style="text-indent:25px">簡介：縮醛聚合物即聚甲醛是由甲醛聚合形成的，它也常稱做聚氧亞甲基(POM)。由甲醛來制備聚合物早在20世紀(jì)20年代就被研究過，但是直到l950年杜邦開發(fā)出Delrin (戴林)以前尚來制得熱穩(wěn)定的材料。均聚物是用非常純的甲醛經(jīng)陰離子聚合制得。形成的聚合物是不溶的。隨著聚合反應(yīng)的進(jìn)行不斷析出。隨著甲醛選出縮醛樹脂被拉開，于是發(fā)生了熱降解。聚合物的熱穩(wěn)定性可通過端羥基與**的酯化來提高。改善熱穩(wěn)定性的另一個(gè)方法是與第二單體：如環(huán)氧乙烷等共聚，其聚物是按陽離子聚合法制備的。聚甲醛材料的熱穩(wěn)定性相對(duì)來講是很差的，它在加熱時(shí)受其溫度的影響容易分解。</p><div

style="text-indent:25px">共聚甲醛生產(chǎn)技術(shù)：共聚甲醛生產(chǎn)技術(shù)是以三聚甲醛與二氧五環(huán)（或環(huán)氧乙烷）為單體，在路易斯酸的作用下共聚的生產(chǎn)技術(shù)。生產(chǎn)共聚甲醛的公司的生產(chǎn)技術(shù)各自具有獨(dú)特的技術(shù)特點(diǎn)，但主要的工藝過程包括甲醇合成甲醛、甲醛合成三聚甲醛，三聚甲醛與第二單體聚合成聚甲醛。目前國內(nèi)外廠商一般均采用本體聚合法，即將原料高純?nèi)奂兹?、第二單體（二氧五環(huán)或環(huán)氧乙烷）和引發(fā)劑（三氟化硼—**絡(luò)合物）按比例混合后，在具有強(qiáng)剪切和混合作用的雙螺桿反應(yīng)器或連續(xù)捏合機(jī)中，完成聚合反應(yīng)后產(chǎn)物經(jīng)氨水處理得到粒狀共聚甲醛。聚甲醛用于注射成型、注塑成型和擠出成型的縮醛樹脂都可買到。上海高分子POM報(bào)價(jià)</p><p

style="text-indent:25px">聚甲醛抗靜電、絕緣改性：聚甲醛絕緣性能特別好，這使得聚甲醛容易產(chǎn)生靜電，從而限制了聚甲醛在石油化工廠及粉塵環(huán)境中的使用。通過添加一定比例的聚乙二醇可使聚甲醛具有永遠(yuǎn)的抗靜電效果。此外，可以通過添加碳納米管、炭黑等常用導(dǎo)電材料以提高聚甲醛的導(dǎo)電性質(zhì)。聚甲醛抗老化、光穩(wěn)定性改性：聚甲醛對(duì)紫外線非常敏感，在強(qiáng)烈的陽光暴曬下，表面會(huì)變得粗糙。使用受阻胺622、292或苯并三唑類紫外線吸收劑UV—P對(duì)聚甲醛進(jìn)行紫外光保護(hù)，也可用炭黑進(jìn)行改性。杭州POM哪家好</p><p
