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(guó)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(rùn)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(chǎng)，如替代鋅、黃銅、鋁和鋼制作許多部件，自問(wèn)世以來(lái)，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(zhǎng)態(tài)勢(shì)。</p><p style="text-indent:25px">聚甲醛技術(shù)發(fā)展方向分析：我國(guó)已成為世界聚甲醛生產(chǎn)大國(guó)，外資公司紛紛進(jìn)入我國(guó)建設(shè)生產(chǎn)裝置。但目前國(guó)內(nèi)中資聚甲醛生產(chǎn)裝置所采用技術(shù)大都從國(guó)外引進(jìn)，且基本為“二流”技術(shù)。我國(guó)聚甲醛生產(chǎn)技術(shù)水平提高緩慢，產(chǎn)品質(zhì)量不穩(wěn)定，仍不能滿足國(guó)內(nèi)高級(jí)市場(chǎng)需求。國(guó)內(nèi)企業(yè)生產(chǎn)大多為普通牌號(hào)的低端產(chǎn)品，產(chǎn)品結(jié)構(gòu)單一，高級(jí)和**改性產(chǎn)品則主要依賴進(jìn)口。國(guó)外改性產(chǎn)品系列和品種眾多，高級(jí)改性產(chǎn)品的應(yīng)用量已經(jīng)達(dá)到了30%以上。聚甲醛電纜護(hù)套阻燃性差： POM本身的阻燃性是比較差（比一般的合成高分子材料都易燃），且熱穩(wěn)定性差，所以POM阻燃很難做到V0，通?？赏ㄟ^(guò)加入阻燃劑來(lái)提高其阻燃性，但由于POM的分子結(jié)構(gòu)特點(diǎn)，常規(guī)的含鹵阻燃劑體系如鹵代磷酸酯、鹵化石蠟、三氧化二銻，在加入到POM中，不僅不會(huì)提高材料的阻燃性，反而會(huì)加劇聚甲醛的燃燒。建議可加入膨脹型阻燃劑：如紅磷、磷酸鹽、氫氧化鋁（鎂）、三氰尿酸和聚氰胺鹽等或其中幾種復(fù)配使用。聚甲醛有較高的粘彈性，電絕緣性優(yōu)，且不受溫度影響；耐絕緣性好且不受濕度影響。</p><div

style="text-indent:25px">再生聚甲醛加什么可以增加韌性和光澤：由于POM結(jié)晶度較高，結(jié)晶晶粒較大，缺口沖擊強(qiáng)度低，往往以脆性方式斷裂，所以改善POM的沖擊韌性主要有2種方法： (1) 彈性體增韌（常用的彈性體如TPU、EPDM、丁腈橡膠、硅橡膠等）; (2) 剛性粒子增韌（常用的有滑石粉、硅藻土、二氧化鈦、碳酸鈣、玻璃微珠等），POM料本身具有表面光滑，有光澤的特點(diǎn)，所以也可以通過(guò)從加工助劑方面來(lái)提高其光澤性，如加入適量的脫模劑，內(nèi)潤(rùn)滑劑等。聚甲醛增韌TPU選擇哪種？用何相容劑？ (1) 采用不同種類的 TPU對(duì)聚甲醛進(jìn)行增韌改性，結(jié)果發(fā)現(xiàn)，聚己內(nèi)酯共聚酯型 TPU 的增韌效果較好； (2) 且TPU的用量對(duì)增韌材料的性能有較大影響，當(dāng)TPU用量為40%時(shí)，由于共混物形成雙連續(xù)相結(jié)構(gòu)，沖擊性能發(fā)生突變，增韌效果zui佳； (3) 也可以通過(guò)添加
