Rock Wool Sandwich panel

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

The disadvantage of rock wool sandwich panel is that its strength is not strong enough, but it is suitable for steel structure workshops, roofs and walls of simple mobile houses, ceilings and partitions of air clean rooms, etc.

basic introduction
The color steel rock wool sandwich panel and its production process realize the compounding of rock wool and steel plate into a whole through automated equipment in the factory, thus changing the previous method of on-site compounding of rock wool panels. , On the premise of sound insulation, fire prevention and other requirements, it has achieved the goals of high quality, high efficiency, reliability and safety. This product has been widely used in Europe and has matured and perfected.

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

1. Excellent fire resistance: The raw materials, production process and formula used in rock wool sandwich panels make it have good fire resistance. Tests have shown that it has a fire resistance of over 1000°C. The rock wool sandwich panel has passed the test of the Italian authoritative testing agency GLOROANO S.P.A. According to the standards of the International Organization for Standardization (ISO), the British BS and the German DIN, the rock wool sandwich panel meets the fire protection standard M.I14/09/61 Letter No. 91 and the requirements of 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 the rock wool sandwich panel is calculated based on the thermal conductivity of rock wool = 0.043W/㎡K and the thickness of the rock wool core material in the corresponding proportion.

3) The sound absorption and heat insulation effect is remarkable:

Sound insulation: The rock wool sandwich panel has a significant reduction effect on noise transmission, especially suitable for places where designated flights pass. In addition, after the rock wool roof panel is used, the indoor sound caused by the impact of rain and hail on the roof steel plate of the building is also significantly reduced. Through the test, according to ISO 717/82 and UNI 8270/7 standards, a sandwich panel with a density of 120kg/m³ rock wool as the core material is selected, and the sound insulation effect can reach RW=29-30 dB

Sound absorption: The rock wool sandwich panel also has an excellent suction effect, which can absorb sound in a relatively 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)..

Folding Disadvantages
The strength is not good enough.

Features
1. Good rigidity: Because the rock wool core material and the two layers of steel plates are bonded into a whole and work together, the overall rigidity is much better than that of the rock wool (glass wool) sandwiched by the pressure plate. Cotton) on-site composite panels. After the sandwich panel is fixed with the purlin by the connector, the overall rigidity of the roof is greatly improved, and the overall working performance of the roof is strengthened. If rock wool sandwich panel is used, a larger purlin distance can be used, so it can save 1/3~2/3 of the purlin consumption.

2. Reasonable buckle connection method: The rock wool roof panel adopts the buckle connection method, which avoids the hidden danger of water leakage in the joints of the roof panel 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 external forces such as typhoons. The self-tapping screw is set at the crest position on the upper surface of the roof panel, and adopts a special waterproof structure to avoid weak points of waterproofing.

4. Short installation period: Because the rock wool sandwich panel does not need secondary processing on site, it 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 is 600~800㎡.

5. Anti-scratch protection: During the production of rock wool sandwich panels, polyethylene self-adhesive protective film can be pasted on the surface to avoid scratches or abrasions on the surface coating of the steel plate during transportation and installation.

folded construction
1) Upper and lower surfaces: galvanized color steel plate with a thickness of 0.4-0.8mm. According to the specific requirements of customers, galvanized color steel plate or galvanized steel plate can also be used. The steel plate is first rolled and formed by a forming machine and then compounded with a rock wool factory.

2) Rock wool core material: Rock wool blocks with a density of 120kg/m&sup3; The rock wool blocks and between the rock wool and the upper and lower steel plates are bonded by high-strength foaming agents to form a whole. The sophisticated production process ensures that the high-density rock wool insulation body and the inner wall of the metal plate can produce extremely Strong adhesive force, so that the rock wool sandwich panel has good rigidity.
