2.按橡膠的外觀形態(tài)：橡膠可分為固態(tài)橡膠(又稱(chēng)干膠)、乳狀橡膠(簡(jiǎn)稱(chēng)乳膠)、液體橡膠和粉末橡膠四大類(lèi)。 3.根據(jù)橡膠的性能和用途：除天然橡膠外，合成橡膠可分為通用合成橡膠、半通用合成橡膠、**合成橡膠和特種合成橡膠。 4.根據(jù)橡膠的物理形態(tài)：橡膠可分為硬膠和軟膠，生膠和混煉膠等。根據(jù)橡膠種類(lèi)及交聯(lián)形式，在工業(yè)使用上，橡膠又可按如下分類(lèi)。一類(lèi)按耐熱及耐油等功能分為:普通橡膠、耐熱橡膠、耐油橡膠以及耐天候老化橡膠、耐特種化學(xué)介質(zhì)橡膠等橡膠O型圈密封性能優(yōu)良，工作壽命高，動(dòng)態(tài)壓力密封工作壽命比常規(guī)橡膠密封制品高5-10倍，較高可達(dá)數(shù)十倍，在某些條件下可與密封基體同壽命。橡膠O型密封圈適合多種不同的密封介質(zhì)。</p><div

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(lèi)，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。黑龍江非標(biāo)橡膠密封件加工廠家</p><p>
