Basic introduction：

The color steel rock wool sandwich panel and its production process have achieved the integration of rock wool and steel plate into a whole through automated equipment in the factory, thus changing the previous method of on-site composite of rock wool panels. While meeting the requirements of building insulation, sound insulation, fire prevention, etc., it has also achieved the goals of high quality, efficiency, reliability, and safety. This product has been widely used in Europe and has matured and improved.

Product characteristics：

advantage:Rock wool sandwich panels fully utilize the unique properties of rock wool core materials, and have significant effects in fire prevention, thermal insulation, sound absorption, and sound insulation.

1Excellent fire resistance: The raw materials, production process, and formula used in rock wool sandwich panels give them excellent fire resistance. Experiments have shown that it has over1000°CFire resistance capability. The rock wool sandwich panel has passed the authoritative testing institution in ItalyGLOROANO S.P.ATesting according to the International Organization for Standardization（ISO）, UKBSAnd GermanyDINAccording to the standard, the rock wool sandwich panel meets the fire protection standardsM.I14/09/61letter91Number andD.M.30/11/83The requirements. The experimental results are as follows:

1）50mmThick rock wool sandwich panelRE130 80mmThick rock wool sandwich panelREL60 100mmThick rock wool sandwich panelREL 120。

2）Good insulation performance: The insulation performance of rock wool sandwich panels is based on the thermal conductivity of rock wool=0.043W/㎡KBased on the thickness of the corresponding proportion of rock wool core material, it is calculated.

3）Significant sound absorption and thermal insulation effect:

Sound insulation: Rock wool sandwich panels have a significant reduction effect on noise transmission, especially suitable for places where designated flights pass through. In addition, after using rock wool roof panels, the impact of rainwater and hail on the roof steel plates of the building caused indoor noise to be significantly reduced. Through testing, according toISO 717/82andUNI 8270/7Standard, choose a density of120kg/m³The sandwich panel with rock wool as the core material can achieve sound insulation effectRW=29-30 dB

Sound absorption: Rock wool sandwich panels also have excellent attraction effects, as they can absorb sounds over a wide frequency range. according toISO 35/85standardThe sound absorption performance level of rock wool sandwich panel has reachedDELTA LA=15.7dB(A)..

disadvantage：The intensity is not good enough.

Having characteristics：

1Good rigidity: Due to the rock wool core material being bonded to two layers of steel plates as a whole and working together, coupled with the wave forming pressure on the surface of the roof panel, its overall rigidity is much better than that of on-site composite panels with rock wool (glass wool) sandwiched between pressure plates. After being fixed with connecting pieces and purlins, sandwich panels greatly improve the overall rigidity of the roof and enhance its overall working performance. By using rock wool sandwich panels, larger purlin spacing can be adopted, which can save the amount of purlin used1/3~2/3.

2Reasonable fastening method: The rock wool roof panel adopts a fastening connection method, which avoids the hidden danger of water leakage at the joints of the roof panel and saves the amount of accessories used.

3The fixing method is firm and reasonable: the rock wool roof panel is made of special materialsM6Self tapping screws are fixed to purlins, which can effectively resist external forces such as typhoons. The self tapping screw is set at the peak position on the surface of the roof panel and adopts a special waterproof structure to avoid the occurrence of weak waterproof points.

4Short installation cycle: Rock wool sandwich panels, as they do not require secondary processing on site, not only maintain the cleanliness of the surrounding environment without affecting the normal progress of other processes, but also greatly shorten the installation cycle of the panels. The daily average installation area of rock wool sandwich panels is up to600~800㎡.

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

structure：

1）Upper and lower surfaces: made of galvanized colored steel plates with a thickness of0.4-0.8mmAccording to the specific requirements of the customer, aluminum zinc coated color steel plates or galvanized steel plates can also be used. The steel plate is first rolled and formed by a forming machine, and then combined with a rock wool factory.

2）Rock wool core material: using a density of120kg/m&sup3;Rock wool blocks are laid in a staggered manner, with the fiber direction perpendicular to the upper and lower surfaces of the sandwich panel, and tightly connected to enrich the entire longitudinal and transverse surfaces of the sandwich panel. The rock wool blocks are bonded together with high-strength foaming agents between the rock wool and the upper and lower steel plates to form a whole. The sophisticated production process ensures that the high-density rock wool insulation can produce extremely strong adhesion between the rock wool insulation and the inner wall of the metal plate, thereby giving the rock wool sandwich panel good rigidity.
