良好的耐化學(xué)性、耐高低溫性、耐臭氧及耐候性。必要時考慮以下屬性:高抗磨損、低摩擦、低壓縮長久變形、彈性好。常用的材料一般有兩種:丁腈橡膠和氟橡膠，一般情況下，材料選擇具有優(yōu)良、多方面性能的丁腈橡膠。對于應(yīng)用溫度超過100℃，或在化學(xué)介質(zhì)條件下，可以選擇氟橡膠。特殊條件下可以選擇其他材質(zhì)。較高的溫度,橡膠會有較短的服務(wù)壽命，如果超過允許溫度，橡膠可能遭受長久性損壞。另外，低溫區(qū)域，如果溫度低于推薦值，橡膠會發(fā)生硬脆現(xiàn)象，然而一旦溫度再次升高,其將恢復(fù)性能。</p><p

2、有自密封作用，往往只用一個密封件便能完成密封效果。 3、密封性能好，用作固定密封時幾乎沒有泄漏，用作運(yùn)動密封時，只在速度較高時才有些泄漏。 4、運(yùn)動摩擦阻力很小，對于壓力交變的場合也能適應(yīng)。 5、尺寸和溝槽已標(biāo)準(zhǔn)化，成本低，產(chǎn)品易得，便于使用和外購。與其它密封圈相比，O形圈也存在問題：起動時的摩擦阻力大。用作氣動裝置的密封時，必須加潤滑油，防止磨損。對偶合配件，如運(yùn)動面、溝槽、間隙等的加工尺寸及精度要求很嚴(yán)。橡膠O型密封圈適合多種不同的密封介質(zhì)。</p><div style="width:100%;text-align:

style="text-indent:25px">O型圈的修邊分為手工、機(jī)械和冷凍等三類: 1。手工修邊。操作者手持刀具，沿著產(chǎn)品的外緣，將溢邊逐步修去。這是較原始的方法。效率低、質(zhì)量難保證，特別對尺寸較小,精度要求高的O型圈難以做到徹底、于凈，而且很容易損及產(chǎn)品本體與溢邊的連接部。往往留下齒痕、缺口，從而留下漏油、漏氣等影響密封的后遺問題。另外。手工修邊對操作熟練程度的依賴也很突出。 2.機(jī)械修邊。為了提高效率和質(zhì)量，出現(xiàn)了機(jī)械修邊。常見的是帶旋轉(zhuǎn)刀刃的**電動修邊機(jī)。所用的刀刃需與制品尺寸高度匹配。如果產(chǎn)品的內(nèi)外緣都有溢邊。則可設(shè)計(jì)成雙刃、多刃口。以實(shí)現(xiàn)一次完成。機(jī)械修邊的加工精度超過手工修邊，效率也有成倍提高，特別對一模多腔的產(chǎn)品而言，可以按照產(chǎn)品的排列與分布，設(shè)計(jì)出與之匹配的刀具。待產(chǎn)品出模后?？烧嫣咨?，一次完成沖切。在加熱的配合下，一次能修幾十個。關(guān)鍵是沖切溫度必須掌握好，防止過高后粘連。橡膠密封件耐熱性能好，硅膠密封圈可在150°℃下長期使用而無性能變化。湖北耐高溫橡膠密封件供應(yīng)廠家</p><p

style="text-indent:25px">橡膠密封件的性能：通常我們所說的天然橡膠，是指從橡膠樹上采集的天然膠乳，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。湖北耐高溫橡膠密封件供應(yīng)廠家</p><p>
