Вермикулит огонь Кирпич

VermiculiteFire brick is cutted or mould product of vermiculite board, itis a non-combustible board in which the unique cellular structure of vermiculite is maintained and controlled by a pre-treatment process. This gives excellent thermal insulation properties with dimensional stability at high temperatures.SpecificationMaximum service temperature1100Bulk Density,dryKG/M3600-1100(available range)Cold crushing strengthMpa2.0-7.2Modulus of ruptureMpa1.31-5.19Linear reheat shinkage12h # 900 degree celsius%<1.0Thermal conductivityMean temp.@200W/(mxK)0.15-0.18@400W/(mxK)0.17-0.20@600W/(mxK)0.19-0.22@800W/(mxK)0.20-0.23Standard size and thicknessThickness20,30,35,40mmLength and width220x110mm,330x220mm,2100x900mm & 1000x610mmOther sizes are available upon requestChemical AnalysisSiO2: 53.39%Al2O3: 11.22%Fe2O3: 3.41%TiO2: 0.73%CaO:1.53%MgO: 13.98%K2O:4.05%Na2O: 6.90%
