纖維密封材料是制造各種發(fā)動(dòng)機(jī)、車輛和機(jī)械裝備的一種基礎(chǔ)零部件材料，主要用于化工、石油、電力、醫(yī)藥等工業(yè)生產(chǎn)過程設(shè)備、壓力容器、管道系統(tǒng)等的密封連接。隨著經(jīng)濟(jì)社會發(fā)展，我國對密封材料的需求快速增長。但令人遺憾的是，國內(nèi)相關(guān)產(chǎn)品質(zhì)量與國際水平相差甚遠(yuǎn)，其中，**造紙法無石棉密封材料，更是一度完全被國外進(jìn)口產(chǎn)品壟斷?！袄w維密封材料包括石棉纖維產(chǎn)品、無石棉纖維產(chǎn)品兩大類。”莊金風(fēng)說，石棉纖維物美價(jià)廉，曾經(jīng)是制造纖維密封材料的*****。后來，由于石棉纖維對于人類健康的危害性逐步被認(rèn)識，發(fā)達(dá)國家漸漸對其禁止使用。在國內(nèi)纖維密封材料中，目前絕大部分仍為石棉纖維產(chǎn)品和輥壓法產(chǎn)品，對此，制造技術(shù)落后是一個(gè)重要原因。莊金風(fēng)介紹，纖維復(fù)合密封材料的生產(chǎn)方法主要有兩種：輥壓法和造紙法。輥壓法生產(chǎn)過程中需要大量使用甲苯、汽油等易燃易爆的有機(jī)溶劑為生產(chǎn)介質(zhì)，不僅安全性差，還易對環(huán)境造成污染、生產(chǎn)效率較低。而采用造紙法生產(chǎn)無石棉密封材料，無需使用有機(jī)溶劑，成本低、污染小、效率高?！斑@種材料在歐美國家早已實(shí)現(xiàn)一次成形的規(guī)?；⑦B續(xù)化生產(chǎn)，但由于涉及交叉學(xué)科，既要懂造紙又需懂材料，我國一直達(dá)不到先進(jìn)?！鼻f金風(fēng)說。

O型密封圈簡稱O型圈，開始出現(xiàn)在19世紀(jì)中葉，當(dāng)時(shí)用它作蒸汽機(jī)汽缸的密封元件。 </p> <p> O型橡膠密封圈有如下的優(yōu)點(diǎn)： </p> <p> 密封部位結(jié)構(gòu)簡單，安裝部位緊湊，重量較輕； </p> <p> 有自密封作用，往往只用一個(gè)密封件便能完成密封； </p> <p> 密封性能較好，用作靜密封時(shí)幾乎可以做到?jīng)]有泄露； </p> <p> 運(yùn)動(dòng)摩擦阻力很小，對于壓力交變的場合也能適應(yīng)； </p> <p> 尺寸和溝槽已標(biāo)準(zhǔn)化，本錢低，便于使用和外購。 </p><div style="width:100%;text-align: center;"><img style="max-width:
