Rockwool sandwich panel:
1) Sealing performance:
Polyurethane double-sided sealing rock wool sandwich panel adopts an assembly line production process, which takes advantage of the excellent water resistance of polyurethane products to overcome the shortcomings of rock wool that is easy to absorb water and deliquescence, and effectively prolongs the service life of the product in terms of physical properties .
2) Beautiful performance:
The interface is designed with European standards, the appearance is round and smooth, the board surface is flat and beautiful, the seam is tight, the strength is reliable, and it effectively prevents the generation of hot and cold bridges.
3) Good rigidity:
The polyurethane double-sided sealing rock wool core material is bonded to the two layers of steel plates to form a whole and work together. In addition, the upper surface of the roof slab is corrugated and pressed, and its overall rigidity is far better than that of the rock wool sandwiched by the pressed slab (Glass wool) on-site composite board. After the sandwich panel is fixed with the purlin by the connecting piece, the overall rigidity of the roof is greatly improved, and the overall working performance of the roof is strengthened. The choice of rock wool sandwich panel can use larger purlin distance, so it can save 1/3~2/3 of the amount of purlin.
4) The buckle connection method is reasonable:
the polyurethane double-sided sealing rock wool roof panel adopts the hidden buckle connection method, which avoids the hidden danger of water leakage in the roof panel joints and saves the amount of accessories.
5) The fixing method is firm and reasonable:
The polyurethane double-sided sealing rock wool roof panel is fixed with special M6 self-tapping screws and purlins, which can effectively resist external forces such as typhoons. Self-tapping screws are set at the crest of the seam between the two panels of the roof panel, and a special waterproof structure is adopted to avoid weak points of waterproofing.
6) Short installation cycle:
Polyurethane double-sided sealing rock wool sandwich panel, because no secondary processing is required on site, it can not only keep the surrounding environment clean and not affect the normal progress of other processes
Pu sealing rockwoool sandwich panels :
1) Excellent fire resistance:
The raw materials, production technology and formula used in the polyurethane double-sided sealing rock wool sandwich panel make it have good fire resistance. Tests have shown that it has a fire resistance over 1000℃.
2) Good thermal insulation:
The thermal insulation of the polyurethane double-sided sealing rock wool sandwich panel is based on the thermal conductivity of the rock wool=0.043 W/m2 K, and the corresponding ratio of the thickness of the rock wool core material is calculated. Got it.
3) Sound insulation and sound absorption effect is remarkable:
The polyurethane double-sided sealing rock wool sandwich panel has a significant reduction in noise transmission, and is especially suitable for places where designated flights pass. In addition, after using rock wool roof panels, rain and hail impact on the roof steel plates of the building and cause indoor noise, which is also significantly weakened. Through the test, in accordance with 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.
Polyurethane double-sided sealing 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. At the same time, it retains the plasticity, high strength, and non-absorption of polyurethane The advantages. The advent of this material is a revolutionary change in construction engineering. The advantages of polyurethane and rock wool have been fully integrated, and the disadvantages of traditional panels have been eliminated. In a sense, ordinary rock wool sandwich panels. cannot be compared with polyurethane double-sided sealing rock wool sandwich panels
