style="text-indent:25px">當(dāng)密封件承受的壓力超過其極限而失效時(shí)，可能是壓力過大的結(jié)果。破壞模式從開裂到完整的結(jié)構(gòu)破壞不等。檢查壓力峰值，并確保密封設(shè)計(jì)符合給定應(yīng)用中的壓力。像溫度一樣，供應(yīng)商為每種密封規(guī)定了推薦壓力以獲得比較好性能（例如Trelleborg Sealing Solutions，其產(chǎn)品專門用于各種液壓應(yīng)用，從輕型線性液壓到重型旋轉(zhuǎn)密封和靜態(tài)應(yīng)用，以及在選擇產(chǎn)品時(shí)可以輕松確定壓力和溫度規(guī)格的位置）。當(dāng)超過建議的壓力時(shí)，密封件磨損會(huì)更快。此外，使用錯(cuò)誤的潤(rùn)滑劑或油可能會(huì)導(dǎo)致流體密度變得太稠或打滑，高速旋轉(zhuǎn)。如果在要求一定速度的環(huán)境中使用（例如旋轉(zhuǎn)軸），則密封墊可能無法承受旋轉(zhuǎn)速度。密封件設(shè)計(jì)為依靠潤(rùn)滑在密封唇和活動(dòng)表面之間滑動(dòng)。潤(rùn)滑膜的厚度確定了摩擦水平。當(dāng)速度增加時(shí)，摩擦力初會(huì)減小，但是隨著時(shí)間的推移，摩擦力會(huì)增加，從而導(dǎo)致密封件磨損。低于和超過建議范圍的速度會(huì)導(dǎo)致摩擦值急劇上升，從而影響密封材料。</p><p> 按密封膠硫化方法分類 </p> <p> 此類密封膠系列利用空氣中的水分進(jìn)行硫化。它主要包括單組分的聚氨酯、硅橡膠和聚硫橡膠等。其聚合物基料中含有活性基因，能同空氣中的水發(fā)生反應(yīng)，形成交聯(lián)鍵，使密封膠硫化成網(wǎng)狀結(jié)構(gòu)。大氣中的濕氣作為硫化反應(yīng)中的催化劑。 </p> <p> 化學(xué)硫化型密封膠 </p> <p> 雙組分的聚氨酯、硅橡膠、聚硫橡膠、氯丁橡膠和環(huán)氧樹脂密封膠都屬于這一類，一般在室溫條件下完成硫化。某些單組分的氯磺化聚乙烯和氯丁橡膠密封膠以及聚氯乙烯溶膠糊狀密封膠（如汽車用點(diǎn)焊膠），則須在條件下經(jīng)化學(xué)反應(yīng)完成硫化。裝O形圈的溝槽尺寸超差，尤其是深度尺寸過大時(shí)，使O形圈安裝后壓縮變形量不足而影響密封能力。</p><div
