碳石墨密封环1 各种

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,

可制作各种形状的密封环、石墨轴承、石墨磨擦片等产品，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.
