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，四川耐油橡膠密封件制造廠家，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，四川耐油橡膠密封件制造廠家、燃料油以及溶劑油的溶脹;耐寒可低到-60℃至-80℃，四川耐油橡膠密封件制造廠家，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。硫化溫度是橡膠O形密封圈發(fā)生硫化反應(yīng)的基本條件之一。四川耐油橡膠密封件制造廠家</p><div

style="text-indent:25px">在模壓硫化過(guò)程中，必須嚴(yán)格正確掌握硫化的溫度、時(shí)間和壓力，并隨時(shí)注意硫化過(guò)程中溫度等參數(shù)的變化情況，進(jìn)行相應(yīng)處理，否則會(huì)造成產(chǎn)品欠硫或過(guò)硫。若采用自動(dòng)控制系統(tǒng)，則整個(gè)硫化過(guò)程會(huì)自動(dòng)記錄和控制，以保證產(chǎn)品達(dá)到正硫化程度。硫化溫度是橡膠O形密封圈發(fā)生硫化反應(yīng)的基本條件之一，它直接影響硫化速度和產(chǎn)品質(zhì)量。硫化溫度高，硫化速度快，生產(chǎn)效率高；硫化溫度低，硫化速度慢。硫化溫度系根據(jù)配方而定，其中較重要的是取決于膠種和所用硫化體系。天然橡膠較適宜的硫化溫度一般為143℃－－150℃，合成橡膠一般為150℃～180℃。硫化時(shí)間通常按照確定的硫化溫度，通過(guò)試驗(yàn)確定硫化時(shí)間。橡膠制品在硫化過(guò)程中加壓，其目的在于使膠料易于流動(dòng)，充滿型腔，防止硫化過(guò)程中產(chǎn)生氣泡，提高產(chǎn)品的致密性。硫化壓力的大小視膠料硬度、模具大小而定。膠料硬度高、模具尺寸大時(shí)，壓力可大些，反之則應(yīng)適當(dāng)減小壓力。</p><p 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。在實(shí)際的需要用到橡膠密封件的產(chǎn)品生產(chǎn)中，正確的選擇橡膠密封件是很重要的。</p><div
