EPDM門窗密封條&機(jī)柜密封條 </p> <p> 門窗密封條的分類：塑鋼門窗密封條，鋁合金門窗密封條，木門密封條，冷 </p> <p> 庫門密封條，糧庫門密封條，阻燃門窗密封條，玻璃密封條，自動(dòng)旋轉(zhuǎn)門密封條，建筑門密封條，幕墻密封條等。門窗密封條特點(diǎn)：塑鋼門窗密封條是近年來應(yīng)用較廣的新一代門窗，它較普通門窗密封條有更好的防腐性、耐候性、降噪隔熱效果。塑鋼門窗密封條表面光潔，不但具有優(yōu)異的密封防水性能，還起著美觀裝飾的作用。在選材方面，一般要求較高的廠家都選用三元乙丙橡膠或熱塑性三元乙丙橡膠。 </p> <p> 機(jī)柜密封條：電氣柜密封條是由具有良好彈性和抗壓縮變形、耐老化、臭氧、化學(xué)作用、較寬的使用溫度范圍（ -40℃~1 20℃）的三元乙丙橡膠 (EPDM) 橡膠發(fā)泡與密實(shí)復(fù)合而成，內(nèi)含獨(dú)特的金屬夾具和舌形扣，堅(jiān)固耐用 . 在各種電氣柜上起著很關(guān)鍵的作用。錦湖三元乙丙膠

三元乙丙橡膠的分子量及分布可以通過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。三元乙丙橡膠的門尼粘度可以反映其分子量的大小，三元乙丙橡膠的門尼粘度范圍通常在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> EPDM耐熱性一： </p> <p> 乙丙橡膠的耐熱及耐熱氧老化性能優(yōu)于其他通用橡膠，只要配合適當(dāng)，乙丙橡膠的長期工作溫度可達(dá)１２０℃，比較高連續(xù)工作溫度為１５０℃，短時(shí)間甚至可耐２３０～２６０℃高溫。這種良好的耐熱老化性能使其成為制造耐熱輸送帶、耐熱膠管等耐熱制品較為理想的彈性體材料。不過，當(dāng)使用溫度高于１５０℃時(shí)，乙丙橡膠便開始緩饅分解。普通牌號(hào)的乙丙橡膠即使不加入耐熱型防老劑，也具有良好的耐高溫性能。加入適當(dāng)防老劑，會(huì)進(jìn)一步改善乙丙橡膠的耐高溫性能。為了獲得硫黃硫化時(shí)比較好的耐熱性能，另外加入一些***防老劑可進(jìn)一步改善膠料的耐熱性能。硫黃硫化ＥＰＤＭ膠料中使用***自由基捕捉型防老劑如防老劑ＡＭ和其與防老劑增效劑如防老劑ＭＢ搭配使用時(shí)，兩種添加防護(hù)體系膠料的耐熱性能均比不加防老劑的時(shí)好。而且兩種防老劑搭配使用比單用自由基捕捉型防老劑好。乙丙橡膠綜合物理機(jī)械性能介于天然膠與丁苯膠之間，與丁基橡膠類似。</p><div

橡膠的擠出成型始于內(nèi)胎成型，逐漸被廣泛應(yīng)用于汽車用內(nèi)飾材料、外飾材料、建筑用材料、管道、電線等領(lǐng)域特別是由于三元乙內(nèi)橡膠的擠壓物表面光滑干凈，主要用于維持形狀等物理特點(diǎn)要求高的地方， </p> <p> 為制造良好的KP三元乙丙橡膠擠出物，必須考慮如下要求特點(diǎn)。 </p> <p> l 分子量 </p> <p> l 分子量分布(MWD) </p> <p> l 乙烯丙烯的組成分布 </p> <p> l 填充劑的種類及擠壓加工性 </p> <p> l 硫化計(jì) </p> <p> 分子量的大小主要反應(yīng)在生膠的門尼上，較低的門尼粘度有助于橡膠的順利擠出，分子量分布寬擠出性能優(yōu)異，乙烯含量對(duì)擠出性能會(huì)有相對(duì)正向的影響，填料方面，炭黑、碳酸鈣相對(duì)于白炭黑而言更利于擠出。 </p> <p> 進(jìn)行擠出加工時(shí)主要發(fā)生的問題包括擠壓量、沖模膨脹、形狀維持性、擠壓物的表面狀態(tài)、給料性等，為解決這些問題，必須注意聚合體的選擇以及填充劑的選擇。三元乙丙橡膠高溫流動(dòng)性較好，故制造模壓制品時(shí)沒有什么困難。錦湖接角用EPDM</p><p style="text-indent:25px">乙丙橡膠的**主要缺點(diǎn)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。錦湖三元乙丙膠 KEP-020P</p><p> 增強(qiáng)改性一： </p> <p> 納米材料增強(qiáng)：用納米技術(shù)能夠在分子水平上重組物質(zhì)結(jié)構(gòu)，從而使新材料具有比傳統(tǒng)材料更優(yōu)越的性能。通過填充納米填料制備橡膠納米復(fù)合材料（分散相至少有一維的尺寸介于１~１００nｍ）已成為目前研究的新熱點(diǎn)。由于納米粒子具有的小尺寸效應(yīng)、量子效應(yīng)、不飽和價(jià)效應(yīng)和電子隧道效應(yīng)等表面效應(yīng)，因此引入納米填料將使橡膠的性質(zhì)發(fā)生很大改變，并有可能獲得一些新的性能。 </p> <p> 納米材料增強(qiáng)ＥＰＤＭ研究近年十分活躍，主要有納米粘土（層狀硅酸鹽）、納米二氧化硅、納米碳酸鈣、炭黑一白炭黑雙相納米填料、納米氧化鋅、納米氫氧化鎂、納米石墨、納米氧化鋁、納米氮化硅、納米丙烯酸金屬鹽、納米ＰＴＥＥ、碳納米管和納米級(jí)纖維等，使ＥＰＤＭ獲得更優(yōu)異、更***的性能，進(jìn)一步拓寬ＥＰＤＭ使用范圍。錦湖三元乙丙膠
