Advantages of SWE Polyurethane Sandwich Panels

1.Heat and sound insulation:The outer steel sheets can maintain the lastingness of the color of the building, and reduce the solar radiation and keep the appropriate indoor temperature. The high quality heat insulation materials are made with the adoption of polyurethane PU and (PIR) polyisocyanurate resin acid hydrogen containing no Chloro-fluoro-carbons (CFC).

2.A degree inflaming retarding:This system can effectively prevent the fire and prevent the fire from spreading during the cross construction and during the use of the boards

3.Environment protection:By learning after the successful experience in environment protection constructions from companies home and abroad and through our scientific analysis, we objectively bear the idea of “low carbon designing, environmental building materials and energy-saving technology” in mind.

4.Super-low heat conductivity:The lowest heat conducting coefficient of the heat insulation boards ensures that, under the condition that the thinnest heat insulation materials are used; the system can meet the energy-saving requirement and offer the strongest basic guarantee to meet the requirement of high standard heat insulation

5.SWE polyurethane roof panel are tightly connected blind nailing

6.Easily and quick installation

Q: Polyurethane sandwich panels polystyrene sandwich panels how to identify? 75 models Price / square?: Polystyrene foam and foam polyurethane alone from the appearance is very easy to identify, the flammability of the former flammable and drip, the latter flame from the fire self-extinguishing and only carbonized insoluble drops. Density is also different, do not know what you mean 75 models. Price, then, the specific specifications of polyurethane color sandwich panels in general 120-170 range; if it is outside the wall insulation board, the price is generally ranging from 50-100.

Q: The concept of glass wool cotton sandwich panels: Composite methods are usually explosive composite, explosive rolling composite, rolling composite and so on. Composite materials can be divided into composite panels, composite pipe, composite bar and so on. Mainly used in anti-corrosion, pressure vessel manufacturing, electric construction, petrochemical, pharmaceutical, light industry, automobile and other industries. Composite material according to the appearance can be divided into composite panels, composite pipe, composite bar and so on.

Q: EPS material sandwich board is fire: Certainly not anti, now switch to rock wool. How are we EPS production. But the amount is still the largest board

Q: What is the difference between the sandwich panel and the composite board?: Metal sandwich panels are made of two-layer metal panels (or other material panels) for the surface material, insulation materials to do the core material, with adhesive composite or direct foam curing molding compound. Building insulation sheet industry in the insulation board refers to the sandwich panels, composite board is popular called. Metal composite panel in the industry refers to a layer of metal plate covered with another metal plate, in order to reduce the use of the effect (corrosion resistance, mechanical strength, etc.) under the premise of saving resources and reduce the cost of the effect.

Q: Will the Yanmian sandwich color steel plate of the plant can reach the fire two grade requirements?: Yanmian sandwich color of the core material is basalt and other natural ore as the main raw material, the high temperature melt into the fiber, adding the right amount of binder, curing and made. Is the same type (sandwich panel series) in the fire resistance of the strongest of a new type of fire board. Applicable to drying room, paint room, industrial equipment, construction, ship insulation, noise, etc., at the same time for electronic clean room, clean room, explosion-proof fire shop ceiling, partition and so on. Fire time is 80 minutes. Some information on "with 600 ℃ fire resistance, fire rating to A level."

Q: Is the foam sandwich panel soundproof?: In terms of sound insulation, the foam board is very good, but if there is a wire recommended not to use foam board, because the wire with a long time will be hot, it is easy to fire. It is recommended to use gypsum board, double, hollow, up and down with a glass gel seal, so that better play a sound insulation effect, if you want a better sound insulation, gypsum board can be replaced by soundproof glass wall, that no matter what noise or what are Solved, is the cost of some more expensive. If you want to block the line of sight can be single-sided glass on the things that ok

Q: What is the polyurethane sandwich board material: Double-sided color steel, the middle of the polyurethane sandwich composite panels Generally used in the roof of the building roof, the board has a good insulation, heat insulation, noise effects, and polyurethane does not help combustion, in line with fire safety. Upper and lower board plus the common role of polyurethane, with high strength and stiffness, the lower plate smooth and smooth, clear lines, increase indoor aesthetics, flatness. Easy installation, short duration, beautiful, is a new type of building materials.

Q: Does the country 's steel market have sandwich panels?: 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. Guoqiang steel market with sandwich panels.

Q: What is the difference between the board and the core board?: Big core board price is cheaper than the core board, the vertical (to the core material to distinguish) bending strength is poor, but the lateral bending strength than ... but generally do not choose the best! Plywood is made of three or more layers of 1mm thick veneer sheet made of hot pressing. Plywood is generally divided into 3mm, 5mm, 9mm, 12mm, ... plywood buy plywood by multi-layer single The plates are arranged in a crisscross arrangement. The outermost front panel is called a panel, and the back is called a backplane. The inner board is called the core plate.
