pom材料制成的板材成型品在我們生活中非常常見，舉個(gè)列子---汽車保險(xiǎn)杠支架，保險(xiǎn)杠大家應(yīng)該都知道，用于汽車碰撞保護(hù)，那么保險(xiǎn)杠支架是什么呢？主要是為了起到固定支撐保險(xiǎn)杠的作用嗎，目前不少汽車的保險(xiǎn)杠支架選擇的是塑料材質(zhì)，因?yàn)榭梢詼p輕質(zhì)量的同時(shí)不會(huì)降低強(qiáng)度，需要材料具有很好的剛性。現(xiàn)在國內(nèi)已經(jīng)有很多商家開始注意到汽車保險(xiǎn)杠用pom材料了，因?yàn)楸ｋU(xiǎn)杠選材中要注意幾點(diǎn)要求，1-良好的尺寸穩(wěn)定性，2-高機(jī)械強(qiáng)度，3-高沖擊強(qiáng)度，不易斷裂，4-良好的耐腐蝕性，5-可注塑性，由于保險(xiǎn)杠支架需要有很好的機(jī)械強(qiáng)度和高抗沖擊特點(diǎn)，而pom料剛好可以滿足這些特性，因此拿來做保險(xiǎn)杠未嘗不可。</p><p> POM材料特性： </p> <p> 1、機(jī)械性能pom聚甲醛具有很好的拉伸強(qiáng)度、彎曲強(qiáng)度、沖擊強(qiáng)度、剛性及彈性。而且在跨度大的溫度范圍內(nèi)，pom仍保持的高剛性。它是非常適合替代金屬的合成樹脂。 </p> <p> 2、耐疲勞性、彈性及耐蠕變性對(duì)于長期的反復(fù)應(yīng)力具有很好的耐疲勞性和彈性的KEPITAL-與各種齒輪類、板彈類、線圈彈性彈簧、偏心輪、扣具部件等結(jié)構(gòu)零件一起，在反復(fù)應(yīng)力、彎曲、沖擊、振動(dòng)等條件下仍具有耐疲勞特性。pom聚甲醛比其它塑料具有更加不錯(cuò)的耐疲勞特性，它是用于受到反復(fù)應(yīng)力的零部件上的非常適合的材料。 </p> <p> 3、耐磨損性耐摩擦磨損性和耐疲勞性、耐蠕變性一樣是pom的主要特性之一。 </p> <p> 4、耐氣候性在室外或有紫外線場所被使用時(shí)，若非極端條件，使用標(biāo)準(zhǔn)牌號(hào)即可滿足要求。如果需要經(jīng)常處于極端環(huán)境溫度中，推薦使用耐氣候牌號(hào)。 </p> <p> 5、尺寸穩(wěn)定性pom材料成型品具有在常溫下長期使用也能維持極高的尺寸穩(wěn)定性的特性。成型后的收縮，根據(jù)其模具溫度有所差異。但此過程1-2小時(shí)開始至2-3天之內(nèi)完成。收縮結(jié)束后在常溫下放置一年以上，其尺寸也基本不變。所以也能用于精密度要求極高的配件上。另外，在極低的溫度和潮濕的環(huán)境中，尺寸變化極小。 POM材料又稱賽鋼、特鋼。它是以醛類，外加其他助劑等為原料聚合所得的材料。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="南通白色pom棒材采購,pom"

POM板棒改性的意義。POM在成形加工過程中極易結(jié)晶，生成尺寸較大的球晶，當(dāng)材料受到?jīng)_擊時(shí)，這些尺寸較大的球晶容易形成應(yīng)力集中點(diǎn)，造成材料的破壞，所以POM缺口敏感性大，缺口沖擊強(qiáng)度低，成型收縮率高，制品易產(chǎn)生內(nèi)應(yīng)力，難于緊密成型。這極大地限制了POM的使用范圍，在某些方面不能滿足工業(yè)要求，因此，為了更好地適應(yīng)高速、高壓、高溫、高負(fù)荷等苛刻的工作環(huán)境，進(jìn)一步擴(kuò)大POM的應(yīng)用范圍，需進(jìn)一步提高聚甲醛的沖擊韌性，耐熱和耐摩擦等性能。</span>
