O型圈材料的壓縮長久變形率與溫度有關(guān)。當(dāng)變形率在40%或更大時，即會出現(xiàn)泄漏，所以幾種膠料的耐熱性界限為：丁腈橡膠70℃，三元乙丙橡膠100℃，氟橡膠140℃。因此各國對O型圈的長久變形作了規(guī)定。中國標(biāo)準(zhǔn)橡膠材料的O型圈在不同溫度下的尺寸變化見表。同一材料的O型圈，在同一溫度下，截面直徑大的O型圈壓縮長久變形率較低。在油中的情況就不同了。由于此時O型圈不與氧氣接觸，般發(fā)生在動密封狀態(tài)。O型圈如果裝配的妥善，并且使用條件適當(dāng)，一般不大容易在往復(fù)運(yùn)動狀態(tài)下產(chǎn)生滾動或扭曲，因?yàn)镺型圈與溝槽的接觸面積大于在滑動表面上的摩擦接觸面積，而且O型圈本身的抗拒能力原來就能阻止扭曲。摩擦力的分布也趨向保持O型圈在其溝槽中靜止不動，因?yàn)殪o摩擦大于滑動摩擦，而且溝槽表面的粗糙度一般不如滑動表面的粗糙度。

O型圈的材料主要有丁氰橡膠NBR和氟橡膠FKM，氟橡膠更適用于高溫工況。除材料之外，O型圈很重要的一個指標(biāo)的是它的硬度，一般采用邵氏硬度來表示，從60到90左右不等，數(shù)值越大表示硬度越高。在同樣壓力下，硬度越高，防擠出(變形甚至撕裂)的能力就越強(qiáng)。因此，應(yīng)選用硬度較高的O型圈。然而，市場上常見的O型圈均為丁氰橡膠制成，邵氏硬度一般O型圈的溝槽設(shè)計有相關(guān)的國家標(biāo)準(zhǔn)，主要分動密封、軸向靜密封和徑向靜密封三種。法蘭、箱蓋等的O型圈采用軸向壓緊更便于裝配和保證密封性能。另外，我國國家標(biāo)準(zhǔn)中的溝槽尺寸標(biāo)準(zhǔn)已顯落后，如國家標(biāo)準(zhǔn)中受內(nèi)壓的O型圈溝槽外徑等于O型圈外徑，而PARKER法蘭接頭的O型圈溝槽外徑小于O型圈外徑。設(shè)計時應(yīng)適當(dāng)參考國外標(biāo)準(zhǔn)。在70左右，難以滿足相當(dāng)一部分工況的要求。有O型圈的密封面不得使用平面密封膠，可以在O型圈上涂少量黃油以使其不脫落。在維修時。阻燃o(jì)型圈進(jìn)口_商品批發(fā)價格。北京丁腈橡膠O型圈銷售廠家</p><p

橡膠O型圈—硫化硫化是橡膠O型圈生產(chǎn)過程結(jié)束前的一道主要工序，一般使用平板硫化或烘箱二段硫化。在實(shí)際生產(chǎn)中，二段硫化是橡膠制品達(dá)到一定的硫化程度之后除去熱源繼續(xù)進(jìn)行加熱硫化的工藝，很多橡膠O型圈生產(chǎn)廠家選擇二段硫化。以三元乙丙橡膠O型圈為例，通常在常溫下硫化℃硫化，再提高硫化溫度至120℃繼續(xù)硫化，溫度加至150℃繼續(xù)硫化。橡膠O型圈生產(chǎn)過程中，含有硅橡膠、氟橡膠或丙烯酸酯橡膠的O型圈更適合選擇二段硫化工藝。橡膠O型圈生產(chǎn)過程主要包括烘膠、切膠，塑煉、混煉、濾膠、硫化成型等，橡膠制品廠家需要根據(jù)膠料加工工藝性能需求合理調(diào)整生產(chǎn)工藝；使用再生膠降低橡膠O型圈生產(chǎn)成本時，橡膠制品廠家還需要結(jié)合再生膠特點(diǎn)，選擇原膠與再生膠并用時，需要將原膠充分塑煉之后再與再生膠進(jìn)行混煉，尤其是天然橡膠與硬質(zhì)丁腈橡膠。北京丁腈橡膠O型圈銷售廠家</p><p
