Rock wool sandwich full play to the unique properties of rock wool core material in fire protection, fire rock wool roof insulation panels, acoustic insulation and other aspects have a significant effect. Fire performance: raw materials, production process and formulation rock wool sandwich panel, and it has good fire resistance. Tests showed that it has over 1000 ° C fire resistance. Rock wool sandwich has passed GLOROANO SPA Italy authoritative testing organizations test, according to the International Organization for Standardization (ISO), the British BS and German DIN standard roof fire rock wool board, rock wool sandwich panels meet fire safety standards M.I14 / 09 / 61 Functional Requirements 91 and DM30 / 11/83's. Test results were as follows: 1) 50mm thick rock wool sandwich RE130 80mm thick rock wool sandwich REL60 100mm thick rock wool color steel polystyrene sandwich REL 120 color steel polystyrene composite panels composite panels are vertical and bedroom two modes of production of new fireproof rock wool board, vertical production is polystyrene foam beads poured into the pressure plate, and then cured by heating from the heating temperature 110-130 ℃ fireproof rock wool board, heating Time 40-60 minutes, 8-10 minutes cooling time; bedroom production is the use of polystyrene foam board as core material, combined with the surface layer of color plate by adhesive.
