Fireproof Soundproof With Without Wire Mesh Or Aluminium Foil Jacket Or Glass Fiber Cloth Rock Wool Mineral Wool Felt Rolls Blankets

IntroductionRock wool mineral wool With high-quality basalt as the main raw material, after melting it, through high-temperature spunning basalt wool into 4~7 μm non continuous fiber with internationally advanced four-roll centrifugal wool production technology, adding a certain amount of binder, dust laying oil and moisture repellent into rock wool fiber, and after technologies of sedimentation, solidification, cutting, etc., the rock wool board are manufactured into series of products with different density according to their different applicationsFeature1.Resistant to high temperatures2.Non-combustible3.Water repellent4.Chemically inert5.No deterioration of performance over timeItemUnitblankettest methoddensityKg/m360-110GB5480.3allowable deviation%±10Average fiberum4-7GB5480.4Slag content(particle diameter      >0.25mm)%≤6GB5480.5water absorption%≤2GB/GB16401-1996Temperature absorption rate%≤1.0GB5480.7Hydrophobicity%≥98B10299-88The thermal shrinkage temperature under load℃≥650GB11835-1998organic content%≤4%GB11835-1998Compressive strength(10% compression ratio)kPa≥40GB/T13480-92Peel strengthkPa≥14DIN52274Non-combustibility--A GradeGB5465Thermal conductivity(70℃)W/mk≤0.041GB10294-88Acidity coefficient≥1.8Binder content%≤3.0Applicationused for the heat insulation and sound absorption in building roofs, Movie theatres, TV Station, Broadcasting & Radio, testing laboratory, Sound absorption setting, cooling air conditioning pipes and insulating heat in cold storage and warehouse
