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> </p><p><span style="font-size:14px;font-family:";"> </span><span style="font-size:14px;font-family:";">所以POM改性研究的關(guān)鍵：</span> </p><p><span style="font-size:14px;font-family:";">①POM的物理改性關(guān)鍵在于復(fù)合體系相間的相容性，應(yīng)加大多功能增容劑的開發(fā)研究。新開發(fā)的凝膠體系及原位聚合離聚體增韌使復(fù)合體系形成穩(wěn)定互穿網(wǎng)絡(luò)，是解決相間相容性的新的研究方向。</span> </p><p><span style="font-size:14px;font-family:";">②POM的化學(xué)改性關(guān)鍵在于在合成過程中通過選擇共聚單體在分子鏈中引入多功能基團(tuán)，為進(jìn)一步的改性提供條件；調(diào)節(jié)共聚單體數(shù)量、優(yōu)化分子結(jié)構(gòu)的設(shè)計(jì)，合成系列化、功能化和高性能化POM。</span>
