产品详细信息
碳化硅密封环2
碳化硅材料具有以下优点:极高化学耐腐蚀性,高的机械强度,高热导率,耐磨自润性好,
适用生产各种机械密封环、轴承、轴套等摩擦材料。故广泛用于石油化工、电力、
轻工、航天、汽车、造纸及污水处理等各工业领域。且与碳石墨配对,摩察系数小,
可用作高参数机械密封。
They have the property of excellent resistant-corrosion, high mechanical strength,high
thermal conductivity, good self-lubrication, used as seal face, bearings and tubes in
spacecraft, machinery, metallurgy, printing and dyeing, foodstuff , pharmaceutical,
auto industry and so on. When the sic faces are combined with graphite faces the
friction is the smallest and they can be made into mechanical seals which are able
to work in highest working requirements.
