机械用炭素材料炭素材料具有良好的耐高温、耐腐蚀及自润滑性，使其在密封领域获得广泛应用。但普通炭一石墨材料强度低、开孔率大，用于流体密封，承压力低，密封性差，必须经过浸渍煤沥青、各种树脂或低熔点金属及其盐类，再经适当的固化，炭化或其它烧结处理。目前，这... Carbon material for mechanical use Carbon material has good high temperature resistance, corrosion resistance and self-lubricating properties, making it widely used in the field of sealing. However, ordinary graphite graphite material with low strength, large opening rate for fluid seal, bearing pressure low, poor sealing, must be impregnated with coal tar pitch, a variety of resins or low melting point metals and their salts, and then by the appropriate curing, Charring or other sintering process. At present, this ...
