      氧化鋁陶瓷密封環(huán)具有耐高溫、耐化學(xué)腐蝕、耐磨損、密封性好的優(yōu)點(diǎn)，能使用于各種耐酸、耐堿、耐油的密封泵及其他密封產(chǎn)品，廣泛適用于石油、化工、制藥、汽車(chē)制造、軍工、航空、冶金、印染、食品、機(jī)械等諸多行業(yè)的密封。

Ceramic seal faces have the property of the resistant high temperature, resistant-corrosion, resistant-wearing and good sealing and are widely used in the spacecraft, machinery, metallurgy, printing and dyeing, foodstuff, pharmaceutical, auto industry and so on.

      硬質(zhì)合金是機(jī)械密封摩擦材料中用量較多的硬面材料，使用范圍較廣泛，耐磨性好，抗彎強(qiáng)度高，導(dǎo)熱系數(shù)高，膨脹系數(shù)小，是所有硬面材料中耐熱沖擊系數(shù)最高的材料。

Tungsten carbide is widely used as seal faces with resistant-wearing, high fractural strength, high thermal conductivity, small heat expansion co-efficent. It is the best material to resist heat and fracture in all hard face materials.

碳石墨材料具有良好的耐腐蝕性，較高的導(dǎo)熱系數(shù)，低的摩擦系數(shù)，自潤(rùn)滑性好，膨脹系數(shù)小，可制作各種形狀規(guī)格的密封環(huán)、石墨軸承、石墨摩擦片等產(chǎn)品，是機(jī)械密封較理想的摩擦副材料。

Graphite has the good property of good resistant-corrosion, high thermal conductivity and lower friction, good self-lubrication, the smaller expansion. They can be made into the seal faces, bearings and so on. It is ideal to choose it as the frictional mating rings.
