Rock wool sandwich panel and its manufacturing process is one the most advanced inventions, which in the factory automation equipment, rock wool and steel into a whole, thus changing the way of the rock wool plate before the compound required site , under the premise that meet the requirements of the building thermal insulation, sound insulation, fire protection, to achieve a high quality, efficient, reliable, safe target. The products in Europe through a wide range of applications, sophisticated.
Purposes: the company of rock wool sandwich panel roof and wall are two types of widely used in a fireproof, sound insulation, thermal insulation requirements of industrial and civil roof, external walls and internal partitions, especially fire demanding projects.
Constructed: (1) upper and lower surfaces: galvanized color steel plate, thickness 0.4-0.8mm. According to the specific needs of customers, may also have galvanized color steel or aluminum plate. Steel plate first and then molding the molding machine rolling with rock wool composite compound. (2) rock wool core material: density 120kg/m3 rockwool blocks staggered laying the fiber direction perpendicular to the sandwich panel, under the surface, and is closely connected to enrich the entire vertical and horizontal cross-section of sandwich panels. Rock wool block and rock wool on the lower steel plate high strength foam adhesive to form an overall excellent production process guaranteed to produce very high-density rockwool insulation body and the metal plate between the inner wall strong adhesion, so the rock wool sandwich panel has good stiffness.
Product specifications: (1) the width of the rock wool sandwich panel <950mm1150mm length <160000mm can be determined according to design requirements and the transportation and installation conditions; (2) Thickness: 50mm, 75mm, 100mm 150mm
Features:
Stiffness (1): rock wool core material with two layers of steel plate bonding as a whole, working together, coupled with the surface wave-pressure on the roof, the overall stiffness of rock wool clip than the pressure plate (glass cotton) on-site composite sheet. Sandwich panels, fittings and purlins fixed, greatly improve the overall stiffness of the roof, and to strengthen the roof of the overall work performance. Choice of rock wool sandwich panel can be used from the larger purlin, purlins amount of 1/3 to 2/3 can be saved.
Reasonable manner: (2) Snap the roof of the rock wool plug cap, avoiding the hidden dangers of the roof joint leaks, saving the amount of parts.
(3) fixed method is reasonably solid: rock wool roof with specially designed M6 self-tapping screws and purlins fixed external force can effectively resist the typhoon. Self-tapping screws set in the roof on the surface of the peak position, and using a special waterproof construction, the avoid waterproof weak point.
(4) short installation cycle: rock wool sandwich panel, due to the site without secondary processing, not only to keep the surroundings clean and tidy, does not affect the normal conduct of other processes, but also greatly shorten the installation cycle of the plate, rock wool sandwich panel The daily average installation area of 600 ~ 800m2.
(5) anti-scratch protection: rock wool sandwich panel production in the surface paste polyethylene self-adhesive protective film, in order to avoid transportation and installation process steel surface coating is scratched or worn.
Advantages: rock wool sandwich panel, give full play to the unique properties of the rock wool core material, fire protection, thermal insulation, sound absorption and sound insulation and other significant efficacy of.
(1) Fire performance: rock wool sandwich panel used raw materials, production technology and formula, it has good fire performance. The tests showed that it has more than 1000 ° C refractory. The results are as follows: 50mm thick rock wool sandwich panel REI30 80mm thick rock wool sandwich panel of REI 60 100mm thick rock wool sandwich panel, REI 120
(2) thermal insulation: the insulation of rock wool sandwich panel insulation is rock wool thermal conductivity λ = 0.043 W/m2. K, as the basis to compute the parameters of the corresponding proportion of the thickness of rock wool core material .
(3) sound insulation sound-absorbing effect is significant:
Sound Insulation: rock wool sandwich panel, the noise transfer a significant reduction, especially suitable for the specified flight by. In addition, the use of rock wool roof, rain, hail on the roof of the building steel impact caused by indoor sound, but also significantly reduced. Pass the test, in accordance with ISO 717/82 and UNI 8270/7 standard, the choice of density 100kg/m3 rock wool core material of sandwich panels, sound insulation effect can be achieved RW, = 29 ~ 30 dB,
Sound absorption: rock wool sandwich panel also has excellent sound-absorbing effect, it absorbs the sound within a wide frequency range. In accordance with ISO 354/85 standard, rock wool sandwich panel sound-absorbing performance level of the DELTA LA = 15.7dB (A).
