三元乙丙橡膠的分子量及分布可以通過(guò)凝膠滲透色譜法使用二氯苯作為溶劑在高溫下（150℃）測(cè)量而得。分子量分布通常被稱為是重量平均分子量與數(shù)量平均分子量的比例。根據(jù)普通和高度支化的結(jié)構(gòu)，這個(gè)值通常在2到5之間變化。三元乙丙橡膠的門(mén)尼粘度可以反映其分子量的大小，三元乙丙橡膠的門(mén)尼粘度范圍通常在20到100之間。 </p> <p> 增加三元乙丙橡膠的分子量，正面影響有：更高的拉伸和撕裂強(qiáng)度，在高溫情況下更高的生坯強(qiáng)度，能夠吸收更多的油和填料（低成本）。但是過(guò)高的分子量也會(huì)使得橡膠的流動(dòng)性能變差，這意味橡膠后續(xù)加工會(huì)更加的困難，比如更難混煉，更難充模，更難擠出等等，隨著分子量分布的增加，正面的影響有：增加的混煉和碾磨加工性。但是，較窄的分子量分布可以改進(jìn)硫化速度，硫化狀態(tài)以及注塑行為。

</p> </p><p> EPDM配方設(shè)計(jì)的方法 </p> <p> a.關(guān)于村科的種類 </p> <p> 此概念的基礎(chǔ)上采取添加所需材料的方法。追求“簡(jiǎn)單的就是比較好的"這排除計(jì)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(chǎng)進(jìn)行原材料管理，以由于近來(lái)各材料生產(chǎn)商都在不斷地開(kāi)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(shí)候添加材料，都可能成為泄漏、起霜等負(fù)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(jì)時(shí)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(jìn)劑(丁晴橡膠混合) 3種以下 </p> <p> 促進(jìn)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(chǎng)使用大型機(jī)械進(jìn)行混煉操作時(shí)，經(jīng)常發(fā)生分散不充分的情況并且如添加量少，將會(huì)發(fā)生分散不均勻的現(xiàn)象。 </p> <p>
