style="text-indent:25px">橡膠密封件的性能：通常我們所說(shuō)的天然橡膠，是指從橡膠樹(shù)上采集的天然膠乳，經(jīng)凝固、干燥等加工工序制成的固狀物。天然橡膠是一種以聚異戊二烯為主要成分的天然高分子化合物，分子式是(C5H8)n，其橡膠烴(聚異戊二烯)含量在90%以上，還含有少量的蛋白質(zhì)、脂肪酸、糖份及灰份等。天然橡膠的物理特性。天然橡膠在常溫下具有較高的彈性，稍帶塑性，具有非常好的機(jī)械強(qiáng)度，滯后損失小，在多次變形時(shí)生熱低，因此其耐屈撓性也很好，并且因?yàn)槭欠菢O性橡膠，所以電絕緣性能良好。橡膠，同塑料、纖維并稱為三大合成材料，是只有具有高度伸縮性與極好彈性的高分子材料。橡膠的較大特征首先是彈性模量非常小，而伸長(zhǎng)率很高。其次是它具有相當(dāng)好的耐透氣性以及耐各種化學(xué)介質(zhì)和電絕緣的性能。某些特種合成橡膠更具備良好的耐油性及耐溫性，能抵抗脂肪油、潤(rùn)滑油、液壓油、燃料油以及溶劑油的溶脹;耐寒可低到-60℃至-80℃，耐熱可高到+180℃至+350℃。橡膠還耐各種曲撓、彎曲變形，因?yàn)闇髶p失小。橡膠的第三個(gè)特征在于它能與多種材料進(jìn)行并用、共混、復(fù)合，由此進(jìn)行改性，以得到良好的綜合性能。</p><p style="text-indent:25px">使橡膠密封件能發(fā)揮出好的性能與使用壽命： 1、首先使用前提是需要選擇合適的密封件材料和液壓油，以便橡膠密封件在工作運(yùn)作中對(duì)溫度的適應(yīng)性，與對(duì)油的相容性。 2、與橡膠密封件相對(duì)滑動(dòng)的幾何位置精度高、材質(zhì)好和表面粗糙度較細(xì)可延長(zhǎng)使用壽命。 3、對(duì)于液壓泵，安裝時(shí)還要用一個(gè)安裝套筒或薄墊片來(lái)保護(hù)密封件，以免唇邊翻卷、扭曲，導(dǎo)致彈簧滑出。 4、液壓缸內(nèi)要常用滾壓加工，這樣不但改善了表面的粗糙度，同時(shí)還可以做冷作硬化處理，有利于延長(zhǎng)密封環(huán)的使用壽命；后續(xù)還需要根據(jù)壓力、滑動(dòng)面的長(zhǎng)度及種類，這些條件決定“定檢”時(shí)間。 5、橡膠密封件面要潤(rùn)滑狀態(tài)良好、防止顆粒侵入；其次使用規(guī)定的油液和正確的安裝方法，是必要的條件。橡膠密封件是密封技術(shù)中普遍應(yīng)用的一類橡膠制品。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">模壓的橡膠O型圈的修邊方法有兩種：即手工修邊和機(jī)械修邊。手工修邊即為較傳統(tǒng)的修邊方法，通過(guò)人工使用刀具沿著產(chǎn)品的外緣逐步的將多余的膠邊修剪去。需要極高的熟練度才會(huì)減少產(chǎn)品的報(bào)廢率。手工修邊投資小，修邊質(zhì)量不高效率低，*適用于小批量產(chǎn)品的加工。機(jī)械修邊的方法有兩種，一種是砂輪砂紙磨削，另一種是低溫冷凍去邊。目前，低溫冷凍修邊的方法有振動(dòng)冷凍修邊、擺動(dòng)或抖動(dòng)冷凍修邊、轉(zhuǎn)鼓冷凍修邊、刷磨冷凍修邊和拋丸冷凍修邊五種形式。橡膠在一定的低溫條件下會(huì)由高彈態(tài)變成玻璃態(tài)，成為玻璃態(tài)的橡膠變硬變脆，硬化變脆的速度與橡膠制品的厚度有關(guān)。當(dāng)把O型橡膠圈放入冷凍修邊機(jī)中，在控制一定的低溫下制品的薄膠邊因?yàn)槔鋬龆冇沧兇?，但是制品本身仍然?huì)保持一定的彈性，隨著轉(zhuǎn)鼓的運(yùn)轉(zhuǎn)，制品之間發(fā)生碰撞，制品與拋丸、磨蝕劑等產(chǎn)生沖擊、磨蝕，膠邊就會(huì)被打碎脫落，達(dá)到修邊的目的。制品會(huì)在常溫下恢復(fù)原有性能。橡膠密封件補(bǔ)償泄漏間隙，達(dá)到密封的目的。山西阻燃橡膠密封件生產(chǎn)工藝</p><p
