防靜電硅橡膠O型圈 氟硅橡膠密封圈尺寸美標(biāo)AS 568系列
耐高溫硅膠密封圈別名:硅橡膠是一種高活性吸附材料,屬非晶態(tài)物質(zhì),其化學(xué)分子式為mSiO2·nH2O。不溶于水和任何溶劑,無(wú)味,化學(xué)性質(zhì)穩(wěn)定,除強(qiáng)堿、氫氟酸外不與任何物質(zhì)發(fā)生反應(yīng)。各種型號(hào)的硅膠因其制造方法不同而形成不同的微孔結(jié)構(gòu)。硅膠的化學(xué)組份和物理結(jié)構(gòu),決定了它具有許多其他同類材料難以取代得特點(diǎn):吸附性能高、熱穩(wěn)定性好、化學(xué)性質(zhì)穩(wěn)定、有較高的機(jī)械強(qiáng)度等。硅膠根據(jù)其孔徑的大小分為:大孔硅膠、粗孔硅膠、B型硅膠、細(xì)孔硅膠
硅膠O型圈有很好的電絕緣性能??估?qiáng)度較一般橡膠差且不具耐油性,硅膠的耐溫范圍溫:-43~210℃,突出的優(yōu)點(diǎn)是擁有優(yōu)良的耐高溫、抗靜電性能,而且通過(guò)特殊配方工藝,可以生產(chǎn)成食品級(jí)材質(zhì)優(yōu)點(diǎn):1、調(diào)制配方后抗張強(qiáng)度可達(dá)到500PSI及抗斯性可達(dá)88LBS。2、良好及具良好的壓縮變形。3、對(duì)中性溶劑具有良好的抵抗性。4、具的抗熱性。5、具的抗寒性。6、對(duì)于臭氧及氧化物的侵蝕具的抵抗力。缺點(diǎn):1、不建議使用于大部分厚縮的溶劑、油品、厚縮酸及經(jīng)稀釋后的氫氧化鈉之中。2、電子行業(yè)的密封件或橡膠零件,如手機(jī)按鍵、DVD內(nèi)的減震墊、電纜線接慶內(nèi)的密封件等。硅膠圈理化性能硅膠圈是以從石英中獲得的硅元素為基礎(chǔ),并由硅原子粘附諸如甲基、乙烯基等側(cè)鏈而形成的飽和非極性橡膠。不同的側(cè)鏈會(huì)導(dǎo)致硅橡膠具有不同的特性。甲基乙烯基硅橡膠(VMQ)是應(yīng)用較多的一種硅橡膠材料。特點(diǎn)硅膠圈具有優(yōu)異的耐熱性、低溫彈性和特別優(yōu)異的耐氧化和臭氧的性能,具有高透氣性和對(duì)氣體透過(guò)的選擇性。良好的電絕緣性能(體積電阻大于10歐.cm,擊穿電壓在30kv/mm以上),耐電暈性和耐電弧性。但添加導(dǎo)電碳黑、鎳粉、鋁粉、銀粉,又可得適當(dāng)之導(dǎo)電性(體積電阻可至5-0.02歐.cm)。硅膠圈的表面能較低,具有吸濕性,可起隔離作用。耐水,但耐水蒸氣不佳,壓力超過(guò)50psi以上不建議使用。與大多數(shù)的油、化學(xué)物和溶劑兼容。一般硅橡膠耐酸堿性佳,耐極性溶劑尚可,不耐烷氫和芳香族油品。不建議使用于大部分濃縮的溶劑、油品、濃酸及稀釋后的火堿溶液中。特種硅橡膠還具有耐輻射、耐燃、耐油等性能。它的拉伸強(qiáng)度低,抗磨損能力弱,一般不用于動(dòng)密封。耐熱性:硅橡膠比普通橡膠具有好得多的耐熱性,可在150°下幾乎永遠(yuǎn)使用而無(wú)性能變化,可在200°下連續(xù)使用10000小時(shí),在350°下亦可使用一段時(shí)間。廣泛應(yīng)用于要求耐熱的場(chǎng)合,熱水瓶密封圈,壓力鍋圈耐熱手柄。耐寒性:普通橡膠晚點(diǎn)為—20°—30°,即硅橡膠則在—60°—70°時(shí)仍具有較好的彈性,某些特殊配方的硅橡膠還可承受極低溫度,如:低溫密封圈。溫度范圍-60℃~225℃,特殊硅橡膠高溫可達(dá)300℃,而低溫可至-100℃。(TR10可在-100℃下)硬度范圍邵氏A25度至90度。顏色黑色、棕色、綠色、白色、紅棕色、黃色、蘭色、紅色、橙色、透明、灰色,也可由客戶指定顏色。美標(biāo)O型圈規(guī)格表(AS-568系列)
