Product characteristics
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:
1) 50mm thick rock wool sandwich board RE130 80mm thick rock wool sandwich board REL60 100mm thick rock wool sandwich board REL 120
2) Good thermal insulation: the thermal insulation performance of rock wool sandwich board is calculated based on the thermal conductivity of rock wool=0.043W/㎡ K and the thickness of rock wool core material in corresponding proportion.
3) Significant sound absorption and heat insulation effect:
Sound insulation: rock wool sandwich panel can significantly reduce noise transmission, and is especially suitable for places where designated flights pass. 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 UNI 8270/7 standards, the density is 120kg/m³ The sound insulation effect of sandwich board with rock wool as core material can reach RW=29-30 dB
Sound absorption: rock wool sandwich board has excellent attraction effect at the same time, it can absorb sound in a 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)
Features
1. Good rigidity: because the rock wool core material and two layers of steel plates are bonded into a whole and work together, and the upper surface of the roof panel is corrugated and profiled, its overall rigidity is far better than the on-site composite plate with rock wool (glass wool) sandwiched on the profiled plate. After the sandwich panel is fixed with purlins through connectors, the overall rigidity of the roof is greatly improved and the overall working performance of the roof is strengthened. The rock wool sandwich board can be used with larger purlin spacing, so the purlin consumption can be saved by 1/3~2/3.
2. The buckle connection method is reasonable: the rock wool roof panel adopts the buckle connection method, which avoids the hidden danger of water leakage at the roof panel joints and saves the amount of accessories.
3. The fixing method is firm and reasonable: the rock wool roof panel is fixed with special M6 self-tapping screws and purlins, which can effectively resist the action of typhoon and other external forces. The self-tapping screw is set at the wave crest position on the upper surface of the roof panel, and special waterproof structure is adopted to avoid waterproof weakness.
4. Short installation period: the rock wool sandwich board can not only keep the surrounding environment clean and tidy without affecting the normal operation of other processes, but also greatly shorten the installation period of the board. The average daily installation area of the rock wool sandwich board is 600~800 ㎡.
5. Anti-scratch protection: During the production of rock wool sandwich board, polyethylene adhesive protective film can be pasted on the surface to avoid scratching or abrasion of the steel plate surface coating during transportation and installation.

structure
1) Upper and lower surfaces: adopt galvanized color steel plate with thickness of 0.4-0.8mm. According to the specific requirements of customers, aluminum-zinc color steel plate or galvanized steel plate can also be used. The steel plate is rolled by the forming machine and then compounded with the rock wool factory.
2) Rock wool core material: 120kg/m³ Rock wool blocks are laid in a staggered manner, and the fiber trend is perpendicular to the upper and lower surfaces of the sandwich board, and closely connected to enrich the entire vertical and horizontal surfaces of the sandwich board. The rock wool blocks and the rock wool and the upper and lower steel plates are bonded by high-strength foaming agent to form a whole. The sophisticated production process ensures that the high-density rock wool heat insulator and the inner wall of the metal plate can produce extremely strong adhesion, so that the rock wool sandwich plate has good rigidity.
Applicable fields
It is widely used for the roof, wall and ceiling and partition of steel structure workshop and simple movable room. Rock wool sandwich panels can generally be customized according to the requirements of customers. The rock wool sandwich panels are the most superior in fire resistance among the series of sandwich panels.
