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，寧波耐高溫pom板批發(fā)，耐熱和耐摩擦等性能，寧波耐高溫pom板批發(fā)。</span>

<p> <span style="font-size:16px;font-family:"Microsoft

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)行百格附著力測試時(shí)無法達(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： </p> <p> 將POM賽鋼塑料基材表面用溶劑擦拭干凈。2.將POM處理劑噴涂在基材上（3-5μm）。3.室溫放置大約10分鐘左右，讓其表干。4.120℃-160℃烘烤。5.取出后冷卻后觀察表面完好即可上漆。寧波耐高溫pom板批發(fā)</p><p
