Ceramic Honeycomb

Honeycomb ceramics is mainly use in chemical industry,metallurgy,petroleum, spice,metal rubber,chemical fiber,medicine,chemical fertilizer.vapor liquefies, sewage treatment as tower padding.It mainly as the support of catalyst,heart exchange media and filtrate substrate. 1Compact honeycomb ceramics chemical analysis item SiO2 AL2O3 MgO Fe2O3 Na2O K2O+CaO value 48-50% 37-39% 7-9% <1% <1% <2% Dimension and other physical properties Dimension Quantity of channels wall thickness inner surface area free space average weight 150*150*300 40*40 0.7mm 883 65% 920kg/m3 150*150*300 25*25 1.0mm 573 68% 770kg/m3 physical properties: Index Unit Value Gross density g/cm3 2.22-2.45 water absorption % <3% mean expansion coefficient 10-6/k-1 a 6.85E06/ specific heat capacity KJ/Kg 850-950 heat conduetivity W/mk 1.5-2.5 temperature application 1300 oper porosity % <3 temperature cycle resistance K 250 acid resistance % >98 2Loose honeycomb ceramics catalysis body chemical analysis item SiO2 AL2O3 MgO Fe2O3 Na2O MgO value 48-51% 31-34% 14-16% <0.5% <0.5% <0.5% Dimension and other physical properties Dimension Quantity of channels wall thickness inner surface area free space average weight 150*150*300 40*40 0.7mm 883 65% 518kg/m3 150*150*300 25*25 1.0mm 573 68% 502kg/m3 physical properties: Index Unit Value Gross density g/cm3 1.9-2.0 water absorption % <30% mean expansion coefficient 10-6/k-1 <2 specific heat capacity KJ/Kg 830-900 heat conduetivity W/mk 1.5-2.5 temperature application 1300 oper porosity % <3 temperature cycle resistance K 300 acid resistance % >98
