三元乙丙膠性能特點：與其他常用的通用橡膠或特種橡膠相比，三元乙丙橡膠的主要性能優(yōu)勢在于以下幾方面：(1)性價比高，生膠密度只有～，是生膠密度**輕的常用橡膠；且可大量填充以降低膠料成本。(2)優(yōu)異的耐老化特性，耐天候、耐臭氧、耐日光、耐熱、耐水，錦湖KUMHONR共混EPDM、耐水蒸氣、耐紫外線，錦湖KUMHONR共混EPDM、耐輻射等老化性能，在與其他不飽和的二烯類橡膠如NR、SBR、BR、NBR、和CR等并用時，EPDM可起到高分子抗氧劑或防老劑的作用。(3)優(yōu)異的耐化學(xué)藥品特性，耐酸、堿、洗滌劑、動植物油、醇、酮等；杰出的耐水、耐過熱水、耐水蒸氣性能；耐極性油性能。(4)優(yōu)良的絕緣性能，體積電阻率1016Q·cm、擊穿電壓30～40MV/m、介電常數(shù)(1kHz，20℃)。(5)適用溫度范圍廣，錦湖KUMHONR共混EPDM，比較低使用溫度-40～-60℃，可長期在130℃條件下使用。三元乙丙橡膠(EPDM)卷材是目前世界公認的性能比較好異的防水材料。錦湖KUMHONR共混EPDM</p><div

EPDM的應(yīng)用領(lǐng)域1.汽車領(lǐng)域：三元乙丙橡膠主要用于汽車上的耐熱軟管、汽車門窗密封膠條、汽車室內(nèi)的橡膠墊、輪胎白色胎側(cè)膠、防護罩，乙丙橡膠與PP的改性材料用于制造汽車方向盤、保險杠、駕駛儀表板、擋泥板、空氣導(dǎo)管、汽車風(fēng)扇、散熱格柵及各種管件等。2.建筑防水材料：建筑業(yè)***使用乙丙橡膠作為防水卷材，具有壽命長（約為30年）、強度大、彈性好、防水可靠、施工方便、危險性小等特點。***地應(yīng)用于防水領(lǐng)域，用于房屋、橋梁、隧道、水庫、堤壩等的防水工程3..電線電纜三元制乙丙橡膠不但具有優(yōu)異的電絕緣性能，而且耐臭氧、耐火、耐候、防老化。因此***用作電力電纜、礦用電纜、***艦艇的電線電纜，X射線直流電壓電纜、原子能裝置用電纜等耐熱和耐高壓等技術(shù)要求較高的領(lǐng)域。在工業(yè)發(fā)達國家，家用電器和辦公設(shè)備耐熱部分也***采用乙丙橡膠作為電線電纜的絕緣材料。另外EPDM具有較高的填料和油類填充性，所以可以填充導(dǎo)電碳黑或其它材料，制得導(dǎo)電或半導(dǎo)電橡膠。錦湖KUMHO

此概念的基礎(chǔ)上采取添加所需材料的方法。追求“簡單的就是比較好的"這排除計量失誤發(fā)生的可能性，材料的種類是越少越好。為便于在場進行原材料管理，以由于近來各材料生產(chǎn)商都在不斷地開發(fā)新材料，村料也就在所難免。因此使用橡膠產(chǎn)品要求性能上年然而，在不能準(zhǔn)確把任何時候添加材料，都可能成為泄漏、起霜等負面因素。把握村料效果的情況下，比較好不要盲目地河地添加材料。 </p> <p> 漫合設(shè)計時適宜的材料種類 </p> <p> 聚合體3種以下 </p> <p> 碳/黑 2種以下 </p> <p> 填充物 2種以下 </p> <p> 軟化劑可塑劑 2種以下 </p> <p> 加工助劑 2種以下 </p> <p> 抗老化劑 2種以下 </p> <p> 促進劑(丁晴橡膠混合) 3種以下 </p> <p> 促進劑(三元乙丙橡膠般混合) 4種以下 </p> <p> b.關(guān)于材料的添加量 </p> <p> “比較低添加量比較好為0.2phr以上”其理由在于，在現(xiàn)場使用大型機械進行混煉操作時，經(jīng)常發(fā)生分散不充分的情況并且如添加量少，將會發(fā)生分散不均勻的現(xiàn)象。 </p> <p> 如果不得已要添加0.1phr以下的量時，需要事先完全與材料混合，使?jié)舛冉档?，此外，氧化鋅的比重為5.6左右時，雖然重量份數(shù)為5Phr.但容量份數(shù)為0.891通常添加量不需要5Phr,比較好是添加3Phr以上，在進行硫化過程中，當(dāng)內(nèi)模被行財，可以考慮混合少量的氧化鋅，但這時比較好添加活性氧化鋅活性氧化鋅)。 </p><p> 乙丙橡膠化學(xué)改性 </p> <p> 盡管乙丙橡膠具有耐熱、抗老化、抗沖擊彈性和低溫性能良好等優(yōu)點，但存在強度低、自粘性及互粘性差，與其他膠種并用時，共混相溶性不好等缺點。為了制備綜合性能更優(yōu)異的橡膠，在技術(shù)上常對乙丙橡膠進行極化改性。改性乙丙橡膠主要是將乙丙橡膠進行溴化、氯化、磺化、順酐化、馬來酸酐化等。乙丙橡膠還通過接枝方法進行改性，以解決乙丙橡膠的分子主鏈為非極性飽和結(jié)構(gòu)存在的強度低、自粘性及互粘性差、本身著色、印刷、電鍍困難、與其它膠種共混并用時相容性差等性能缺點，從而拓展了乙丙橡膠在許多方面的應(yīng)用。乙丙橡膠的**主要缺點是硫化速度慢；與其它不飽和橡膠并用難，自粘和互粘性都很差，故加工性能不好。</p><div

密煉煉時的檢查項目 </p> <p> 在現(xiàn)場進行內(nèi)部混煉時，容易發(fā)生分散不良、物性不良等問題，為防止發(fā)生這些問題，要注意如下檢查點。 </p> <p> l 產(chǎn)品的特點與混合方法(混煉模式)是否選擇正確? </p> <p> l 選擇的聚合體的形態(tài)是?(大包、松散塊狀、顆粒狀、碎屑等) </p> <p> l 批量號投入適量嗎? </p>
