100°C溫度范圍內(nèi)長(zhǎng)期使用。它的耐磨性和自潤(rùn)滑性也比絕大多數(shù)工程塑料優(yōu)越，又有良好的耐油，耐過氧化物性能。很不耐酸，不耐強(qiáng)堿和不耐月光紫外線的輻射。聚甲醛的拉伸強(qiáng)度達(dá)70MPa，吸水性小，尺寸穩(wěn)定，有光澤，這些性能都比尼龍好，聚甲醛為高度結(jié)晶的樹脂，在熱塑性樹脂中是zui堅(jiān)韌的。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。提高聚甲醛的耐候性：在聚甲醛中加入抗氧劑及光穩(wěn)定劑可以提高聚甲醛的耐候性。針對(duì)POM受紫外線照射易發(fā)生白化、龜裂等缺點(diǎn)，一些科研機(jī)構(gòu)紛紛開發(fā)出耐候型品種，以滿足汽車內(nèi)外裝飾材料的要求。導(dǎo)電、抗靜電聚甲醛：采用加入炭黑、碳纖維、不銹鋼纖維等導(dǎo)電填充料的方法，可以提高聚甲醛導(dǎo)電性能。在聚甲醛中加入特殊的抗靜電劑則可使聚甲醛具有抗靜電性，減少其在電子領(lǐng)域應(yīng)用時(shí)因灰塵、碎屑積聚及靜電荷產(chǎn)生的干擾。</p><p style="text-indent:25px">聚甲醛(POM)注塑工藝要點(diǎn)：1.滯留時(shí)間：如設(shè)備沒有熔膠滯留點(diǎn)，則POM-H 可在215℃滯留35分鐘;POM-K 可在205℃滯留20分鐘不會(huì)有嚴(yán)重的分解。在注塑溫度下熔體不能在機(jī)筒內(nèi)滯留超過20分鐘。POM-K在240℃下可滯留7分鐘。如果停機(jī)，機(jī)筒溫度可降到150℃，如要長(zhǎng)期停機(jī)就必須清理機(jī)筒子，關(guān)閉加熱器。 2.停機(jī)：清理機(jī)筒必須用PE或PP，關(guān)閉電熱，把螺桿推在前位。料筒和螺桿必須保持清潔。雜質(zhì)或污垢會(huì)改變POM的過熱穩(wěn)定性(尤其是POM-H)。所以當(dāng)用完含鹵聚合物或其它酸性聚合物后，應(yīng)用PE清理干凈后才能打POM料。若作用不當(dāng)?shù)念伭?、?rùn)滑劑或含GF尼龍的物料，會(huì)導(dǎo)致塑料降質(zhì)。 3.后處理：對(duì)于非常溫使用的制件且質(zhì)量要求較高，須進(jìn)行熱處理。退火處理效果，可將制品放入濃度為30%的鹽酸溶液中浸30分鐘檢查，然后用肉眼觀察判斷是否有殘余應(yīng)力的裂紋產(chǎn)生。聚甲醛通過甲醛聚合所得之聚合物，聚合度不高，且易受熱解聚。</p><div style="width:100%;text-align: center;"><img
