</p><p> 注意事項(xiàng)氟橡膠的主要特性是耐高溫和耐化學(xué)腐蝕，并有很好的抗老化和抗臭氧的性能，且滲氣度也非常低。即使在非常惡劣的工作條件下，仍然有非常好的耐磨性。氟橡膠能承受+200度或以下的工作溫度，也能允許短時(shí)間無油情況下的運(yùn)行。氟橡膠可以抵抗油、液壓油、燃油、潤滑劑、無機(jī)酸、脂族烴和芳族烴等，但在有酯、醚、酮、某些胺和高溫的氟水氫等化合物的情況下，不應(yīng)使用氟橡膠。在正常工作條件和工作溫度在+200度以下，氟橡膠是非常穩(wěn)定和無害的。但遇到300度以上高溫時(shí)，如火焰，氟橡膠會釋放出有害的氣體。吸入這些氣體或進(jìn)入眼睛會對人體健康造成損害。氟橡膠密封圈一旦被加熱到300度以上的高溫，即使在冷卻后處理也會有危險(xiǎn)，因此絕不可直接對皮膚的任何接觸。環(huán)保阻燃o(jì)型圈-環(huán)保阻燃o(jì)型圈批發(fā)、促銷價(jià)格、產(chǎn)地貨源。</p><div

摩擦力與O型圈的應(yīng)用在動(dòng)密封裝置中，摩擦與磨損是O型圈損壞的重要影響因素。磨損程度主要取決于摩擦力的大小。當(dāng)液體壓力微小時(shí)，O型圈摩擦力的大小取決于它的預(yù)壓縮量。當(dāng)工作液體承受壓力時(shí)，摩擦力隨之工作壓力的增加而增大。在工作壓力小于20MPa的情況下，近似地呈線形關(guān)系。壓力大于20MPa時(shí)，隨著壓力的增加，O型圈與金屬表面接觸面積的增加也逐漸緩慢，摩擦力的增加也相應(yīng)緩慢。在正常情況下，O型圈的使用壽命隨著液體壓力的升高將會近似的呈平方關(guān)系而減小。摩擦力的增加，使得旋轉(zhuǎn)或往復(fù)運(yùn)動(dòng)的軸與O形密封圈之間產(chǎn)生大量的摩擦熱。由于多數(shù)O型圈都是用橡膠制成的，導(dǎo)熱性極差。因此，摩擦熱就會引起橡膠的老化，導(dǎo)致O型圈實(shí)效，破壞其密封性能。摩擦還會引起O型圈表面損傷，使壓縮量減小。嚴(yán)重的摩擦?xí)芸煲餙型圈的表面損壞，失去密封性。作氣動(dòng)往復(fù)運(yùn)動(dòng)用密封時(shí)，摩擦熱還會引起粘著，造成摩擦力進(jìn)一步增加。運(yùn)動(dòng)用密封在低速運(yùn)動(dòng)時(shí)，摩擦阻力還是引起爬行的一個(gè)因素，影響元件和系統(tǒng)的工作性能。所以對運(yùn)動(dòng)密封來說，摩擦性是重要性能之一。摩擦系數(shù)是摩擦特性的一個(gè)評價(jià)指標(biāo)，合成橡膠摩擦系數(shù)較大，由于密封在運(yùn)動(dòng)狀態(tài)時(shí)。耐油o型圈_耐油o型圈價(jià)格_質(zhì)量耐油o型圈批發(fā)/采購/產(chǎn)地貨源。重慶O型圈生產(chǎn)廠家</p><p
