Jiangsu rock wool sandwich corrugated board foam fireproof sandwich board color steel plate model room composite board

Rock wool sandwich board is a sandwich board made of rock wool. Rock wool sandwich panel gives full play to the unique performance of rock wool core material, and has remarkable effects in fire prevention, heat insulation, sound absorption and sound insulation. The disadvantage of rock wool sandwich board is that its strength is not strong enough, but it is suitable for steel structure factory buildings and simple Activity room Roof wall , ceiling and partition of air clean room, etc. Advantages The rock wool sandwich panel gives full play to the unique performance of rock wool core material, and has remarkable effects in fire prevention, heat insulation, sound absorption and sound insulation. 1. Good fireproof performance: the raw materials, production process and formula used for rock wool sandwich board make it have good fireproof performance. The test shows that it has a fire resistance of more than 1000 ° C. The rock wool sandwich board has passed the test of Italian testing agency GLOROANO S.P.A. According to all standards (ISO), British BS and German DIN standards, the rock wool sandwich board meets the fire protection standard M I14/09/61 Letter No. 91 and D M. 30/11/83. The test results are as follows: 1) 50mm thick rock wool sandwich panel RE130 80mm thick rock wool sandwich panel REL60 100mm thick rock wool sandwich panel REL 120 2) Good thermal insulation performance: the thermal insulation performance of rock wool sandwich panel is calculated based on the thermal conductivity of rock wool=0.043W/㎡ K and the thickness of rock wool core material in the corresponding proportion. 3) Significant sound absorption and heat insulation effect: sound insulation: rock wool sandwich panel has a significant reducing effect on noise transmission, especially applicable to places where * * * flights pass by. In addition, after the rock wool roof panel is adopted, rainwater and hail will affect the roof of the building steel plate The indoor sound caused by impact is also significantly reduced. Through the test, according to ISO 717/82 and UNI 8270/7 standards, rock wool sandwich panel with density of 120kg/m ³ is selected as the core material, and the sound insulation effect can reach RW=29-30 dB sound absorption: rock wool sandwich panel also has a good absorption effect, which can absorb sound in a wide frequency range. According to ISO 35/85 standard, the sound absorption performance level of rock wool sandwich panel reaches DELTA LA=15.7dB (A)
