style="text-indent:25px">聚甲醛改性的進(jìn)展：均聚甲醛密度、結(jié)晶度、熔點(diǎn)較共聚甲醛高，但其熱穩(wěn)定性、酸堿穩(wěn)定性較共聚甲醛低。近年來(lái)為了改進(jìn)聚甲醛性能、擴(kuò)大其應(yīng)用領(lǐng)域，國(guó)內(nèi)外研究人員對(duì)其進(jìn)行了不同方向的改性研究。其中研究人員在聚甲醛的增韌方面采用了彈性體增韌、樹(shù)脂增韌和無(wú)機(jī)剛性粒子增韌方法進(jìn)行改性。在耐磨改性方面采用了耐磨高聚物改性、潤(rùn)滑油/油脂/復(fù)合潤(rùn)滑劑改性和無(wú)機(jī)潤(rùn)滑劑改性的方法進(jìn)行改性。 21世紀(jì)以前我國(guó)聚甲醛工業(yè)發(fā)展比較緩慢，聚甲醛改性研究及其成果較少。隨著近年我國(guó)聚甲醛工業(yè)的快速發(fā)展，改性聚甲醛研究進(jìn)展較快，跟蹤世界聚甲醛改性研究的前沿我國(guó)聚甲醛的生產(chǎn)和研究機(jī)構(gòu)都取得了豐碩的成果。從應(yīng)用方向上說(shuō)聚甲醛改性研究方向13-14有增強(qiáng)改性、增韌改性、耐磨改性、阻燃改性、導(dǎo)電功能改性、超細(xì)復(fù)合粉體改性等方面。南京功能性POM價(jià)格聚甲醛耐沖擊和降低模具沉積牌號(hào)，也有無(wú)機(jī)填充，增強(qiáng)牌號(hào)。</p><div

POM吸水性小，一般為0.2%-0.5%。在通常情況下，POM不需干燥就能加工，但對(duì)潮濕原料必須進(jìn)行干燥。干燥溫度80℃以上，時(shí)間2小時(shí)以上，具體應(yīng)按供應(yīng)商資料進(jìn)行。 2.回用料：再生料使用比例一般不超過(guò)20-30%。但要視產(chǎn)品的種類和zui終用途而定，有時(shí)可達(dá)99%。 3.塑機(jī)的選用： POM是結(jié)晶料，zui好用結(jié)晶料專業(yè)螺桿或尼龍PA螺桿，但POM的加工范圍寬泛，用一般注塑機(jī)也可以。 4.模具及澆口設(shè)計(jì)：常見(jiàn)模具溫度控制為80-90℃，流道直徑有3-6mm，澆口長(zhǎng)度為0.5mm，澆口大小要視膠壁厚度而定，圓形澆口直徑至少應(yīng)制品厚度的0.5-0.6倍，長(zhǎng)方形澆口的寬度通常是厚度的2倍或以上，深度為壁厚的0.6倍，脫模斜度40′-1°30′之間。</p><p style="text-indent:25px">聚甲醛pom有毒嗎：POM無(wú)毒，但是加工方法不當(dāng)就會(huì)產(chǎn)生毒氣。在加工時(shí)，POM會(huì)釋放一種刺激性難聞氣體，但對(duì)人體的危害是不大的，產(chǎn)品做出來(lái)后的POM制品（聚甲醛）常溫下裂解是相當(dāng)緩慢的但是如果在特殊條件下，比如說(shuō)高溫，或者裂解催化劑存在的條件下會(huì)進(jìn)行的很快，聚甲醛（POM）在注塑生產(chǎn)過(guò)程中會(huì)有少量的甲醛氣體產(chǎn)生，在正常的生產(chǎn)條件下，不會(huì)產(chǎn)生嚴(yán)重的問(wèn)題。但是聚甲醛在高溫220攝氏度下就會(huì)發(fā)生熱降解，尤其是在長(zhǎng)時(shí)間處于高溫下時(shí)，容易產(chǎn)生大量的甲醛氣體。這種氣體是刺激性的，對(duì)眼部和咽喉都有傷害。吸入過(guò)多會(huì)有暈眩惡心感。POM熱分解時(shí)會(huì)揮發(fā)出有毒氣體，對(duì)人體產(chǎn)生危害。但是，這與加工成型工藝有很大關(guān)系。加工工藝好和工作環(huán)境好的工廠，是不會(huì)出現(xiàn)安全問(wèn)題的，放心工作好了。聚甲醛具抗熱強(qiáng)度，彎曲強(qiáng)度，耐疲勞性強(qiáng)度均高，耐磨性和電性能優(yōu)良。</p><div
