密封膠的品種及類型很多。為了滿足同一使用要求，可以使用幾種不同基料的密封膠；而同一種基料又能制造出不同性能和不同的用途的密封膠。從密封膠的制造者和使用者兩方面考慮，密封膠有多種分類方法。一般可按下述四種方法進(jìn)行分類。 </p> <p> 按密封膠基料分類 </p> <p> 橡膠型 </p> <p> 此類密封膠以橡膠為基料。常用橡膠有聚硫橡膠，硅橡膠，聚氨酯橡膠，氯丁橡膠和丁基橡膠等。 </p> <p> 樹(shù)脂型 </p> <p> 此類密封膠以樹(shù)脂為基料。常用樹(shù)脂有環(huán)氧樹(shù)脂、不飽和聚酯樹(shù)脂、酚醛樹(shù)脂、聚丙烯酸樹(shù)脂、聚氯乙烯樹(shù)脂等。 </p> <p> 油基型 </p> <p> 此類密封膠以油料為基料。常用的油類有各種植物油如亞麻油，蓖麻油和桐油，以及動(dòng)物油等。 </p><p style="text-indent:25px">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(guò)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(huì)發(fā)展，我國(guó)對(duì)密封材料的需求快速增長(zhǎng)。但令人遺憾的是，國(guó)內(nèi)相關(guān)產(chǎn)品質(zhì)量與國(guó)際水平相差甚遠(yuǎn)，其中，**造紙法無(wú)石棉密封材料，更是一度完全被國(guó)外進(jìn)口產(chǎn)品壟斷。“纖維密封材料包括石棉纖維產(chǎn)品、無(wú)石棉纖維產(chǎn)品兩大類。”莊金風(fēng)說(shuō)，石棉纖維物美價(jià)廉，曾經(jīng)是制造纖維密封材料的*****。后來(lái)，由于石棉纖維對(duì)于人類健康的危害性逐步被認(rèn)識(shí)，發(fā)達(dá)國(guó)家漸漸對(duì)其禁止使用。在國(guó)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(duì)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(guò)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(duì)環(huán)境造成污染、生產(chǎn)效率較低。而采用造紙法生產(chǎn)無(wú)石棉密封材料，無(wú)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(guó)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(guó)一直達(dá)不到先進(jìn)?！鼻f金風(fēng)說(shuō)。機(jī)械密封的工作溫度不能超過(guò)其規(guī)定值。</p><div

style="text-indent:25px">目前，污水泵產(chǎn)品常用的密封形式有兩種:填料密封和機(jī)械密封。填料密封，如圖1所示，是古老的一種密封結(jié)構(gòu)，發(fā)源于工業(yè)**之前的傳統(tǒng)密封裝置，有著100年的材料工藝、潤(rùn)滑劑系統(tǒng)和制造方法，并保持持續(xù)進(jìn)步，目前很多的應(yīng)用場(chǎng)合。經(jīng)分析，該軟填料密封結(jié)構(gòu)存在如下缺點(diǎn):1.密封介質(zhì)含有的雜質(zhì)嚴(yán)重影響密封性能。雜質(zhì)進(jìn)入軟填料密封內(nèi)部，進(jìn)一步增大了填料密封和軸套之間的摩擦、磨損。雖然材料耐磨性較好，但是使用效果仍然不佳，泄漏頻繁。另外由于沒(méi)有采用封液對(duì)填料密封進(jìn)行潤(rùn)滑冷卻，也加劇了填料與軸套之間的磨損。2.工作狀態(tài)不穩(wěn)定需頻繁調(diào)整和更換填料。由于軟填料自身具有的粘彈特性，在工作狀態(tài)下會(huì)出現(xiàn)明顯的應(yīng)力松弛。為保持其正常的密封功能，需不斷地通過(guò)壓緊壓蓋來(lái)增大填料與軸的徑向接觸力，同時(shí)也增大了軟填料與軸的磨損，因此不得不經(jīng)常更換(或添加)填料，維修工作量和費(fèi)用較大增加。3.磨損嚴(yán)重致使能耗量大。根據(jù)軟填料密封的工作機(jī)理，填料密封與軸(或軸套)之間必須保持較大的徑向接觸壓力以維持密封，因此填料和軸(或軸套)的摩擦、磨損都很嚴(yán)重，在密封很快失去工作能力的同時(shí)，造成相當(dāng)大的能耗浪費(fèi)。蘇州重型密封哪家比較好</p><p
