苯膠點高的礦物油、潤滑脂、多種防凍劑，在下列介質(zhì)中耐溶漲性適中：礦物油、低分子量脂烴。使用溫度范圍-35℃~140℃。2.丙烯酸脂橡膠ACM是丙烯酸乙脂或丙烯酸丁脂的共聚物，以ACM為基的比以NBR或CR為基的彈性體的耐熱性高，具有優(yōu)良的耐老化和耐臭氧性，在發(fā)動機油、傳動油、ATF油中耐溶漲性優(yōu)良。使用溫度范圍-25℃～140℃，主要用于制造高溫和含添加劑油條件下的密封制品，在這類工況，丁腈橡膠不符合使用要求，但使用氟橡膠成本太高。湖北耐高溫非標橡膠墊片尺寸和溝槽已實現(xiàn)了標準化，價格便宜，產(chǎn)品易得，便于使用和購買。</p><div

style="text-indent:25px">幾大類墊片的選用解析：工業(yè)橡膠板天然橡膠適用于水、海水、空氣、惰性氣體、堿類、鹽類水溶液等介質(zhì)，但不耐礦物油和非極性溶劑，長期使用溫度不超過90℃，低溫性能優(yōu)異，可在-60℃以上使用。丁腈橡膠適用于石油類產(chǎn)品，如石油、潤滑油、燃料油等，長期使用溫度為120℃，如在熱油中可耐150℃，低溫為-10~-20℃。氯丁橡膠適用于海水、弱酸、弱堿、鹽溶液，耐氧和臭氧老化性能優(yōu)異，耐油性次于丁腈橡膠而優(yōu)于其他通用橡膠，長期使用溫度低于90℃，較高使用溫度不超過130℃，低溫為-30~-50℃。氟橡膠有多個品種，它們分別具有良好的耐酸、耐氧化性能以及耐油、耐溶劑性能?？梢栽趲缀跛械乃犷惤橘|(zhì)以及一些油和溶劑中使用，長期使用溫度低于200℃。橡膠板材作為法蘭墊片，多用于管道或經(jīng)常拆卸的人孔、手孔，壓力不超過1.568MPa。因在各類墊片中，橡膠墊片較軟，貼合性能好，在較小的預(yù)緊力下就能發(fā)揮密封效果。正因如此，在承受內(nèi)壓時，因墊片偏厚或硬度偏低而容易被擠出。</p><p style="text-indent:25px">橡膠密封圈材質(zhì)種類及O型圈配方設(shè)計： 1、ACM丙烯酸脂橡膠密封圈：對油品有較佳的抵抗力，耐高溫、耐候性均佳，但機械強度、壓縮變形率及耐水性稍差。一般用于汽車傳動系統(tǒng)及動力轉(zhuǎn)向系統(tǒng)之中。不適用于熱水、剎車油、磷酸酯之中。一般使用溫度范圍為－25～170 ℃。2、NR天然橡膠密封圈：橡膠制品具有很好的耐磨性、彈性、扯斷強度及伸長率。但在空氣中易老化，遇熱變黏，在礦物油或汽油中易膨脹和溶解，耐堿但不耐強酸。適合于在汽車剎車油、乙醇等有氫氧根離子的液體中使用。一般使用溫度范圍為－20～100 ℃。對微小缺陷起密封作用的就是0形環(huán)所承受的壓力。</p><div style="width:100%;text-align:

style="text-indent:25px">墊片選用：1.、進口設(shè)備（包括儀器儀表）上墊片更換原則是型式及材料原樣更換。因特殊原因墊片形式或材料需更換時，需經(jīng)審批。 2.、墊片的型式和材料應(yīng)根據(jù)流體、使用工況（壓力、溫度）以及法蘭接頭的密封要求選用。法蘭密封面型式和表面粗糙度應(yīng)與墊片的型式和材料相適應(yīng)。3.、石棉或柔性石墨墊片用于不銹鋼或鎳基合金法蘭時，墊片材料中的氯離子含量不得超過 50PPm 。4.、柔性石墨材料用于氧化性介質(zhì)時，較高使用溫度應(yīng)不超過 450 ℃ 。5.、公稱壓力小于或等于 1.6MPa 的法蘭，采用纏繞式墊片、金屬包覆墊片等半金屬墊或金屬環(huán)墊時，應(yīng)選用帶頸對焊法蘭等剛性較大的法蘭結(jié)構(gòu)型式（非常重要）。具有良好的耐磨性、耐老化性及氣密性，因而在橡膠工業(yè)中應(yīng)用普遍。湖北耐高溫非標橡膠墊片</p><p

style="text-indent:25px">板式熱交換器橡膠墊片密封原理：橡膠與金屬彈簧的彈性不同，是一種粘彈材料這就意味著橡膠在長期變形的情況下會發(fā)生應(yīng)力松弛，即在不變的張力或壓力下，密封應(yīng)力會隨時間的延長而衰減。較高的應(yīng)力松弛是限制熱交換器橡膠墊片使用壽命的重要因素。應(yīng)力松弛有兩種,一種是物理松弛,這是因聚合物分子和填充劑微粒之間的重排引起的，此種重排隨著橡膠的變形而逐漸接衡，密封應(yīng)力與時間的對數(shù)呈線性關(guān)系。另一種是化學(xué)松弛，這是因橡膠交聯(lián)網(wǎng)中化學(xué)鍵的開裂引起的。氧化與溫度是影響此種松弛的重要因素。因此應(yīng)力松弛的速率在很大程度上就取決于溫度和每種橡膠墊片所適用的工作溫度范圍。低溫丁腈適用于低溫范圍，因此，隨著溫度上升，其應(yīng)力松弛迅速惡化，而適于高溫范圍的氟橡膠則相反。湖北耐高溫非標橡膠墊片</p><p>
