                      氧化铝陶瓷密封环具有耐高温、耐化学腐蚀◣、耐磨损、密封性好的优点,能使用于各↓种耐酸、耐碱、耐油的密封泵及其他密封产品▓,广泛适用于石油、化工、制药、汽车制造、军工、航空、冶金、印染、食品、机械等诸』多行业的密封。

                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.







                      硬质合金是机械密封摩擦材料中用量较多的硬面材料,使用范围较广泛,耐磨性好,抗弯强度■高,导热系数高,膨胀系数≡小,是所有硬面材料中耐热冲击系数最高的材料。

                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♂良好的耐腐蚀性,较高的导热系数,低的摩擦系数,自润▂滑性好,膨胀系数小,可制】作各种形状规格的密封环、石墨轴承、石墨∩摩擦片等产品,是机械密封较理想的摩擦副材料。

                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.
