large hole-opening ceramic arch

Large hole-opening ceramamic arch,dome and bride are new support structure used in dry and absorption tower in sulfuric acid plant. They have great advantages over the former support in uniform gas distribution, high strength and stabilityj, corrosion-resistance and convenient for installation Major technical parameters of large hole-opening ceramic ball arch Item unit Index Criteria Density g/cm3 2.3-2.6 ZBG94003 Water absorption % 0.2 G8488-2001 Resistance to crook Mpa ≥4.5 GB8488-2001 Resist Compression Mpa 200 Zbg94003-86 Thermal stability 250-20 No cleavage thrice GB8488-2001 Porosity % 62-68 Specification M ≤8.3 Acid proof % ≥99.8 DIN Alkali proof % >87 DIN Crook Error % <0.5 DIN Chemical composition SiO2 72 Al2O3 20.31 K2O 3.7 Na2O 0.8 MgO 0.65 Fe2O3 0.74 CaO 0.58 TiO2 0.09 IL 0.35 Hole fraction: ≥65% Size:Dmax0.5 2.0M or according to the user
