Color steel rock wool sandwich board and its production process realize that rock wool and steel plate are combined into a whole through automatic equipment in the factory. This has changed the way in which rock wool panels need to be compounded on site before. On the premise of meeting the requirements of building thermal insulation, sound insulation, fire prevention, etc., the goal of high quality, efficiency, reliability and safety has been achieved. This product has been widely used in Europe and has matured. advantage

Rock wool sandwich panels give full play to the unique performance of rock wool core materials, and have significant effects in fire prevention, thermal insulation, sound absorption and insulation.

1. Excellent fireproof performance: the raw materials, production process and formula of 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 panel has passed the test of GLOROANO S.P.A, the Italian authoritative testing agency. According to the standards of the International Organization for Standardization (ISO), British BS and German DIN, the rock wool sandwich panel meets the requirements of the fire protection standards M.I14/09/61 letter 91 and D.M.30/11/83. The test results are as follows

2. 50mm thick rock wool sandwich board RE130 80mm thick rock wool sandwich board REL60 100mm thick rock wool sandwich board REL 120

3. Good thermal insulation: the thermal insulation performance of rock wool sandwich panel is based on the thermal conductivity of rock wool=0.043W/mk, and the corresponding ratio

The thickness of rock wool core material in example is calculated.

4. Significant sound absorption and heat insulation effect: sound insulation: rock wool sandwich panel has a significant reduction effect on noise transmission, especially applicable to the passage of designated flights

Of the city. In addition, after the use of rock wool roof panels, the indoor sound caused by the impact of rain and hail on the roof steel plate of the building is also significantly weakened. Through the test, according to ISO 717/82 and UN18270/7 standards, the density is 120kg/m³ The sound insulation effect of the sandwich board with rock wool as the core material can reach RW=29-30 dB sound absorption: the rock wool sandwich board has excellent attraction effect at the same time, it can absorb the sound in a relatively wide frequency range. According to ISO 35/85 standard, the sound absorption performance level of rock wool sandwich board reaches DELTA LA=15.7dB (A)

purpose

It is widely used in the roof, wall and internal partition of industrial and civil buildings with fire protection, sound insulation and thermal insulation requirements, especially for projects with high fire protection requirements.
