POM塑料板棒掉漆的原因及POM板棒底涂劑的使用方法。POM塑料俗稱賽鋼，也稱之為聚甲醛，其表面噴漆出現(xiàn)油漆難附著掉漆的現(xiàn)象主要是由于其高結(jié)晶度和高密度，表面極性差，油漆與POM賽鋼基材表面無(wú)法有效形成極性基團(tuán)的牢固結(jié)合，因此在噴涂橡膠漆或塑膠漆等其他油漆時(shí)，易出現(xiàn)油漆脫落的現(xiàn)象，進(jìn)行百格附著力測(cè)試時(shí)無(wú)法達(dá)到附著力要求。在噴涂工藝中，POM聚甲醛賽鋼塑料表面橡膠漆可獲得手感細(xì)膩、綿滑、柔軟的觸感體驗(yàn)，同時(shí)也附加耐磨等性能，如噴漆塑膠漆時(shí)還可獲得豐富的色彩。綜合其噴涂掉漆的原因，關(guān)鍵是在于基材與油漆涂層之間的附著力。因此通過(guò)打底法，使用POM賽鋼底涂劑，活化材質(zhì)表面，并發(fā)生分子間作用力及機(jī)械結(jié)合力等，同時(shí)與油漆之間形成化學(xué)鍵合效應(yīng)，優(yōu)化附著力結(jié)合強(qiáng)度，從而解決掉漆現(xiàn)象，同時(shí)底涂劑的應(yīng)用替代和改進(jìn)POM賽鋼塑料表面噴砂處理工藝，保證表面平整度和涂裝質(zhì)量.因此POM賽鋼塑料表面噴砂處理施工方法：

style="font-size:14px;font-family:";"> POM板棒改性的意義。POM在成形加工過(guò)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>

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(kāi)發(fā)研究。新開(kāi)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(guò)程中通過(guò)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> 進(jìn)口POM棒相比國(guó)產(chǎn)POM來(lái)說(shuō)，區(qū)別就是料更純一些，內(nèi)部雜質(zhì)更少，料的內(nèi)部無(wú)氣孔，而且是消除了應(yīng)力的。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
