Polyurethane edge sealing glass fiber cotton sandwich panel

Polyurethane edge-sealed glass wool sandwich panels are recognized as the best fireproof and thermal insulation panels for steel structure building enclosures. It has low thermal conductivity, good load resistance, high flexural strength, does not absorb water, does not rot, does not get bitten by insects and rats, has good flame retardancy, high fire protection level and wide temperature resistance range. Utilizing the physical properties and unique formula of polyurethane (PU.PIR), the polyurethane foaming agent is evenly sprayed on the color-coated steel plates, so that the foaming agent is foamed between the color-coated steel plates to form three layers of one-time molded polyurethane ( PU.PIR) color steel composite sandwich panel. This new lightweight building material is a perfect combination of color-coated steel plates and polyurethane, and is the development direction of lightweight building materials.

Features

Performance features:

(1) Sealing performance: The polyurethane double-sided sealed glass wool sandwich panel adopts an assembly line production process, thereby taking advantage of the excellent waterproof properties of polyurethane products to overcome the shortcomings of glass wool that easily absorbs water and deliquesces, and effectively extends the use of the product in terms of physical properties. life.

(2) Aesthetic performance: The interface is designed according to European standards. The appearance is round and smooth, the board surface is smooth and beautiful, the joints are tight, and the strength is reliable, effectively preventing the occurrence of hot and cold bridges.

(3) Good stiffness: The polyurethane double-sided sealed glass wool core material and two layers of steel plates are bonded into a whole and work together. In addition, the upper surface of the roof panel is corrugated and pressed, and its overall stiffness is far better than that of profiled plates sandwiched with glass fibers. On-site composite panels of cotton (glass wool). After the sandwich panels are fixed to the purlins through connectors, the overall integrity of the roof is greatly improved.

Stiffness enhances the overall working performance of the roof. By using glass wool sandwich panels, larger purlin spacing can be used, so the amount of purlins can be saved by 1/3 to 2/3.

(4) Reasonable fastening method: The polyurethane double-sided sealed glass fiber wool roof panels adopt a hidden buckle connection method, which avoids the hidden danger of leakage at the seams of the roof panels and saves the amount of accessories.

(5) The fixing method is firm and reasonable: The polyurethane double-sided sealed glass wool roof panels are 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 position between the joints of the two roof panels, and a special waterproof structure is adopted to avoid waterproof weak points.

(6) Short installation cycle: Polyurethane double-sided sealed glass wool sandwich panels do not require secondary processing on site, which not only keeps the surrounding environment clean and does not affect the normal progress of other processes, but also greatly shortens the installation cycle of the panels. Glass wool sandwich panels The average daily installation area of cotton sandwich panels reaches 600~800m2.

(7) Anti-scratch protection: During the production of polyurethane double-sided sealed glass wool sandwich panels, a polyethylene self-adhesive protective film can be pasted on the surface to prevent the surface coating of the steel plate from being scratched or worn during transportation and installation.

advantage:

(1) Excellent fire resistance: The raw materials, production process and formula used in the polyurethane double-sided sealed glass wool sandwich panel make it have very good fire resistance. Tests have shown that it has fire resistance exceeding 1000°C.

(2) Good thermal insulation

(3) Significant sound insulation and sound absorption effects: Polyurethane double-sided sealed glass fiber wool sandwich panels can significantly reduce noise transmission, and are especially suitable for places where designated flights pass. In addition, after using glass wool roof panels, the indoor sound caused by the impact of rain and hail on the building's roof steel panels is also significantly reduced. pass

Testing, in accordance with ISO717/82 and UNI 8270/7 standards, using a sandwich panel with a density of 120kg/m3 glass wool as the core material, the sound insulation effect can reach RW=29~30 dB.

The glass wool sandwich panel also has excellent sound absorption effect, and it can absorb sound in a wide frequency range. In accordance with ISO 354/85 standards, the sound absorption performance level of glass wool sandwich panels reaches DELTA LA=15.7 dB(A).

The polyurethane double-sided sealed glass wool sandwich panel gives full play to the unique properties of the glass wool core material and has significant effects in fire prevention, thermal insulation, sound absorption and sound insulation. At the same time, it retains the plasticity, airtightness, high strength and non-absorbency of polyurethane. The advantages. The advent of this material is a revolutionary change in construction engineering, making polyethylene

The advantages of urethane and glass wool are fully integrated, eliminating the shortcomings of traditional boards. In a sense, polyurethane double-sided sealed glass wool sandwich panels cannot be compared with ordinary glass wool sandwich panels.
