style="text-indent:25px">聚甲醛自身的特性：在分子鏈中含有—CH2O—鏈節(jié)的熱塑性樹脂就是所謂的聚甲醛，聚甲醛是一種無支鏈線性聚合物，具有著高密度和高結(jié)晶的性質(zhì)，同時還具備著良好的耐化學(xué)品的性質(zhì)和物理機(jī)械性能，使用的范圍也是非常的普遍的，即使是在零下四十?dāng)z氏度和零上一百攝氏度的環(huán)境下也是能夠長期使用的。聚甲醛具有高規(guī)整性的分子鏈結(jié)構(gòu)，主要的組成部分是碳氧鍵。在聚甲醛a中，碳碳鍵要遠(yuǎn)遠(yuǎn)的長于碳氧鍵，具備著十分優(yōu)異的機(jī)械強(qiáng)度和剛性，在所有工程塑料中的機(jī)械性能聚甲醛是zui為接近金屬材料的。聚甲醛具備著非常多的優(yōu)點(diǎn)，其中zui為明顯的幾點(diǎn)就是結(jié)晶度高、自潤滑的性能比較好、密度比較高、剛性較大、成型加工簡單、耐摩擦、耐疲勞以及耐有機(jī)溶劑等。同時聚甲醛具有著一定的光澤，尺寸相對來說也是比較的穩(wěn)定，它只有著很小的吸水性，在這些方面的性能要遠(yuǎn)遠(yuǎn)的高于尼龍。此外，聚甲醛還具備著非常高的彎曲強(qiáng)度、抗拉強(qiáng)度記憶耐疲勞性強(qiáng)度，即使是在一些氣溫非常低的環(huán)境下，聚甲醛仍然具備著非常出色的幾何穩(wěn)定性、抗蠕變特性以及抗沖擊的特性，在低溫的環(huán)境中可以進(jìn)行長期的使用，聚甲醛其他的一些特性也要比其他的一些工程塑料較好很多。</p><p style="text-indent:25px">用途：普遍用于制造各種滑動、轉(zhuǎn)動機(jī)械零件，做各種齒輪、杠桿、滑輪、鏈輪，特別適宜做軸承，熱水閥門、精密計量閥、輸送機(jī)的鏈環(huán)和輥?zhàn)?、流量計、汽車?nèi)外部把手、曲柄等車窗轉(zhuǎn)動機(jī)械，油泵軸承座和葉輪燃?xì)忾_關(guān)閥、電子開關(guān)零件、緊固體、接線柱鏡面罩、電風(fēng)扇零件、加熱板、儀表鈕；錄音錄像帶的軸承；各種管道和農(nóng)業(yè)噴灌系統(tǒng)以及閥門、噴頭、水龍頭、洗浴盆零件；開關(guān)鍵盤、按鈕、音像帶卷軸；溫控定時器；動力工具，庭園整理工具零件；另外可作為沖浪板、帆船及各種雪撬零件，手表微型齒輪、體育用設(shè)備的框架輔件和背包用各種環(huán)扣、緊固件、打火機(jī)、拉鏈、扣環(huán)；醫(yī)療器械中的心臟起博器；人造心臟瓣膜、頂椎、假肢等。用于化工、制藥等化學(xué)合成及使用無水甲醛作原料的合成方面。聚甲醛除了酸性物質(zhì)耐受性差以外，對大部分的化學(xué)試劑耐受性都非常好。</p><div

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。聚甲醛具有優(yōu)良的電絕緣性、耐溶劑性和可加工性，是五大通用工程塑料之一。杭州食品級POM銷售廠家</p><p
