1. The effect of environmental protection and noise prevention is remarkable. The sound insulation strength of the composite board can reach 40-50 decibels, which is a very effective sound insulation material. Sound insulation: Rock wool sandwich panel has a significant mitigation effect on noise transfer, especially for selected flights. In addition, the indoor sound caused by rock wool roof panels, rain, and hail impact on the roof panels of buildings are also significantly reduced. The sound insulation effect can reach RW=29-30dB. The rock wool sandwich panel has a good suction effect at the same time, and it can absorb sound in a relatively wide frequency range. According to ISO35/85 standard, the sound absorption performance level of rock wool sandwich panel reaches DELTAL=15.7 decibels
2.Strong plasticity The profiled steel plate can be cut arbitrarily to meet the needs of special design.
3. High strength Using high-strength steel plate as the base material, the tensile strength is 5600 (kg/cm2), coupled with the most advanced design and roll forming, has excellent structural characteristics
4. Flexible installation: The width of the sandwich panel is type 950 and type 1150, and the surface layer can be compressed or not, and the length can be produced according to the length of the user's requirements. The construction period is short and the comprehensive cost is low;
5. Scope of application: purification engineering (medical engineering, biological engineering, electronic engineering), ships, food, air conditioning, factories, boiler rooms, floors, mobile rooms, cold storage, warehouses, office separation, sound insulation, etc.
6. Among the characteristics of sandwich panels, good fire resistance is more significant: Rock wool sandwich panels are used for raw materials, production processes and formulas, and they have good fire resistance. Tests show that it has a fire-resistant rock wool sandwich panel with a temperature of over 1000°C. The fire-resistant rock wool sandwich panel is tested by the authoritative Italian testing organization GLOROANOS.PA. According to the International Organization for Standardization (ISO), British BS, and German DIN standards, the rock wool sandwich panel meets fire safety standards. The number of letters and M.I14/09/6191 of DM30/11/83 are required.
7. Beautiful, the clear lines of the profiled steel plate reach dozens of colors, which can meet the needs of any style of building.
8. Thermal insulation Commonly used thermal insulation materials include: rock wool, glass fiber cotton, polystyrene, polyurethane, etc., with low thermal conductivity and good thermal insulation effect.
