Guangzhou fireproof rock wool sandwich an excellent fire performance, 2, 3, good thermal insulation, thermal insulation sound absorption effect is significant. Rock wool sandwich full of the unique properties of wool core material in fire protection, thermal insulation, acoustic insulation and other aspects have a significant effect. 1, fire performance: raw materials, production processes and the use of rock wool sandwich recipe, and it has good fire resistance. Tests showed that it has over 1000 ° C fire resistance. Rock wool sandwich panel has passed the authoritative testing organizations GLOROANO SPA Italy tested in accordance with the International Organization for Standardization (ISO), the British BS and German DIN standards, rock wool sandwich panels meet fire safety standards M.I14 / 09/61 91 No. letter and DM30 / 11/83 requirements. Test results are as follows: 1) 50mm thick rock wool sandwich RE130 80mm thick rock wool sandwich REL60 100mm thick rock wool sandwich REL 120 2) Insulation resistance: insulation performance rockwool sandwich panel is thermal conductivity to rockwool = 0.043W / ㎡K as the basis for the thickness of the mineral wool core of the corresponding proportion of the calculation obtained. 3) sound-absorbing insulation effect is remarkable: insulation: rock wool sandwich panel for noise abatement deliver significant role, especially for a place designated by the flight. In addition, the use of rock wool roof, rain, hail on the roof of the building steel interior noise caused by the impact, but also significantly reduced. Tested in accordance with ISO 717/82 and UNI 8270/7 standard, the choice of sandwich density 120kg / m3 wool as the core material, sound effect can be achieved RW = 29-30 dB acoustic: rock wool sandwich at the same time has excellent suction effect that can absorb sound within a relatively wide frequency range. Specifications: Width :( sandwich) 1150mm.950mm (sandwich watts) 960mm thickness:. 50mm.75mm.100mm Scope villas, residential areas, schools, buildings, garden pavilion, shopping malls, scenic spots, public buildings, large-span steel structure housing, flat to pitched, activity room, etc.
