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。聚甲醛添加硅油、礦物油、油脂等潤滑油及潤滑脂類。</p><div

style="text-indent:25px">聚甲醛耐磨改性：聚甲醛本身具有較好的自潤滑性、耐磨性和**度，但是作為滑動部件的普通聚甲醛材料，難以滿足精密機(jī)械、電子電器等動力傳導(dǎo)零部件高速、高壓、高溫、輕量化的要求，所以需要進(jìn)行自潤滑性、耐磨性能的改進(jìn)。耐磨改性主要以物理共混改性為主，耐磨共混改性根據(jù)共混原料的不同分為聚甲醛/耐磨聚合物體系、聚甲醛/潤滑油脂體系、聚甲醛/無機(jī)潤滑劑體系等。可添加的物質(zhì)有硅油、聚四氟乙烯、二硫化鉬、超高分子量聚乙烯、石墨、炭黑、潤滑油、潤滑脂等。聚甲醛熔點(diǎn)低，熱穩(wěn)定性，耐化學(xué)腐蝕性，流動特性，加工性均優(yōu)于均聚甲醛。杭州POM哪家好</p><p style="text-indent:25px">聚甲醛建議將模具溫度控制在80-100°C(通常輸送熱油)。進(jìn)口POM批發(fā)廠家</p><p style="text-indent:25px">聚甲醛的國內(nèi)應(yīng)用現(xiàn)狀：我國聚甲醛的消費(fèi)結(jié)構(gòu)與國外大致相同，只是在汽車行業(yè)的消費(fèi)比例還比較低。但隨著我國汽車工業(yè)的快速發(fā)展，聚甲醛生產(chǎn)汽車零部件會被越來越多的汽車生產(chǎn)廠家接受，因此聚甲醛在汽車行業(yè)的消費(fèi)量將會逐漸增加。另外我國電子電器行業(yè)的發(fā)展十分迅速，聚甲醛在國內(nèi)電子電器行業(yè)的消費(fèi)比例雖然已經(jīng)達(dá)到西歐的水平(西歐為34%左右)，但我國的電子電器行業(yè)還未達(dá)到西歐的發(fā)展程度，因此隨著今后電子電器行業(yè)發(fā)展，聚甲醛在此行業(yè)的消費(fèi)量將穩(wěn)步提高。進(jìn)口POM批發(fā)廠家</p><p
