SSiC печать

(silicon carbide or sic mechanical seal gasket,bushing,ring,oil seal,pump seal, seal face)The silicon carbide has the advantages of excellent corrosion resistance,high coefficient of heat conductivity,self-lubricity,small expansion.It can be widely used in the petroleum,chemical,machinery-building,cosmonautics and motors industries.The frictional factor of combination of silicon carbide and carbon graphite is the least,so it widely applied to high characteristics for the mechanical seals.Main Performance Index Of Reaction bonded silicon carbide(RB SIC):1:Density(g/cm3):3.05-3.082:Hardness(HV):27003:Porosity(%):<0.24:Compressive Strenghth(Mpa):>3505:Free-si value(%):8-126:Purity(Sic percentage)(%): 887:Elastic modulus(Gpa):4008:Poisson ratio:0.149:Thermal conductivity(Cal/cm.s.)0.30
