Q:How to install the wall rock wool sandwich panels: 1, handling the plate should also be lifted at both ends, so as not to damage the appearance of oxide film or coating. When installing the wall panel, only one board can be lifted at one time. It should be used for the special fixture supplied by the manufacturer of the rock wool sandwich panel. Lifting process to slow down, to use the wind rope to be controlled to prevent the wall with the device has been bump, scaffolding raised parts with soft data package. 2, sandwich plate fixation method: one is the self-tapping screw through the wall directly to the wall in the secondary structure. Another method is the self-tapping screw connected directly to the wall sub-structure via the coupling.

Q:Can polyurethane sandwich panels be used for cold storage?: Polyurethane sandwich panels can be used to make cold storage, polyurethane sandwich panels are two-component liquid polyurethane AB material through the prefabricated production line. Polyurethane sandwich board in the polyurethane material is isocyanate and polyether as the main raw material, in the foaming agent, catalyst, flame retardants and other additives under the action of foam polymer. Polyurethane rigid foam is a new type of synthetic material with insulation and waterproof function, its thermal conductivity is low, only 0.022 ~ 0.024W / (m · Κ), equivalent to half of the extruded plate, is the thermal conductivity of all insulation materials lowest. Cold storage polyurethane insulation generally have two kinds of technology, one is the use of sandwich panel on-site stitching, and another process is the use of polyurethane spray coating on-site spraying foam, compared to the first process, the second process because it is on-site spraying foam Any seams, greatly avoid the phenomenon of hot and cold joints, insulation effect is better than the first process.

Q:Sandwich board is used to do what ah ??: Should be "sandwich board" was right. Sandwich panel products are composed of two layers of metal panels (or other material panels) and directly in the middle of the panel foam, mature molding of the composition of the polymer core insulation. These sandwich panels are easy to install, lightweight and efficient. Filling system is also used to close the molecular structure, you can put an end to the condensation of water vapor. The forming of the outer steel sheet takes into account the structural and strength requirements, and takes into account the appearance, the inner layer is formed into a flat plate to suit various needs. Sandwich panels for large industrial plants, warehouses, gymnasiums, supermarkets, hospitals, cold storage, activities, building plus layer, clean workshop and the need to heat insulation fire places.

Q:Pressure plate composite insulation board and the difference between the sandwich panels, the price difference is large? What kind of geng good for steel structure plant design?: The top of the plant with sandwich panels

Q:Chongqing polyurethane sandwich panel manufacturers, Chongqing polyurethane sandwich board which is good: [Three wish]: XY01: just business, and you hope to establish opportunities for cooperation! mutual benefit! XY02: Our quality products and services can get your approval to help you solve the problem! XY03: hope to be able to establish long-term opportunities for you, your support, we have great power!

Q:Use the foam color steel sandwich panel after decoration: Paste the gypsum board with a gauze plate on the sandwich panel. The seams of the gypsum board may be properly reinforced with self-tapping screws to prevent cracking at the joints. Then, in accordance with the normal order of operation to wear bandages, approved scraping putty, polished, and finally brush on the latex paint on the line, the effect of the same with the ordinary wall.

Q:Color steel 50 mm rock wool sandwich board one meter how much the price: I am a Schwab rock wool sales 5 cm 100K color steel plate rock wool sandwich panel is 22 a flat

Q:Can the sandwich panels be used to make hoods: Look at the strength of this board, and some are possible. Our factory's showcase is a kind of sandwich board. Board need to be fixed. And then install the hood, because we mainly do display, do not know whether long-term use will lead to loose. Want to use or will rely on a certain loose. It is recommended to normal home improvement or fixed in a solid wall is better. Such as short-term use can be used sandwich panels. But the board is to be fixed

Q:How to install the cold sandwich sandwich sandwich panels: If the use of polyurethane cold storage board, then use the structure of the installation of the installation time can be reported to us can also install their own This is a drawing in accordance with the drawings can be installed

Q:Whether the rock wool sandwich panel can replace the firewall for fire partition separation: Can not. The fire resistance of the firewall is not less than 3 hours. And rock wool sandwich board fire resistance up to only 2 hours. With rock wool sandwich panel replacement, the equivalent of reducing the fire rating. The above is a personal opinion.
