Application
Polyurethane sandwich panels are widely used in large industrial plants, cold storage, garages, mobile houses, exhibition halls, exhibition halls, stadiums, shopping malls, airports, power plants, villas, hospitals, stratum and high-rise office buildings and other fields. Due to excellent thermal insulation The performance is mainly applied to the roofs and walls of industrial and civil buildings.
It is generally used for building roof outer panels. This panel has good heat preservation, heat insulation and sound insulation effects, and polyurethane does not support combustion, which is in line with fire safety. The combined effect of the upper and lower panels with polyurethane has high strength and rigidity. The lower panel is smooth and flat, with clear lines, which increases the indoor beauty and flatness. Easy to install, short construction period and beautiful, it is a new type of building material.
The sandwich panel has light weight, beautiful appearance and good corrosion resistance, and can be directly processed. It provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, and electrical industry. Good results such as wood replacement, efficient construction, energy saving, and pollution prevention.

Advantage:
1. Efficient insulation
The composite board has the lowest thermal conductivity (≤0.022) among the organic thermal insulation materials, and the 5cm thick polyurethane composite board is equivalent to the thermal insulation effect of 1m thick concrete.
2. Super flame retardant
The composite board will not burn through after 30 minutes of flame at 1000℃.
3. Durable weather resistance
The composite board has been tested for weather resistance for more than 6 months, and its various properties are stable and can be used for the same life as the building.
4. Good dimensional stability
The compressive strength of A-grade polyurethane composite board is above 200kp, and the board has good temperature resistance and no deformation.
5. Low carbon and environmental protection
Polyurethane composite board uses bio-based raw materials, non-fluorine foam, does not use harmful substances prohibited or restricted by the state, and is green and environmentally friendly.

What is Polyurethane Composite Board?

Polyurethane composite board is also called PU sandwich board.
The composite board with polyurethane as the core material is composed of upper and lower color steel plates and intermediate foamed polyurethane. It adopts the world's advanced six-component online automatic operation mixing and casting technology, which can complete the proportioning and mixing process of social batching centers or factories online at one time. And it can be adjusted online at will according to the temperature, so as to produce distinctive high-strength, energy-saving, green and environmentally friendly building boards.
Because of its good fire-proof and moisture-proof performance, it is also often used as the edge-banding core material of other material composite panels. The polyurethane edge-banding composite panel uses high-quality color coated steel plate as the surface material, continuous rock wool and glass wool as the core material, and high-density hard The foamed polyurethane is filled with tongue and groove, after high-pressure foaming and curing, the cotton cloth is automatically densified and is made of super-long double-covered belt control molding compound. Compared with traditional cotton maintenance materials, it has better fire and heat preservation effects and longer performance , Easy installation and elegant appearance. It is a leader in steel building maintenance materials.

How to install composite trim board?
1. Clean up the rubbish on the ground, including no corners. If the ground cannot be cleaned, you will feel "sandy" under the floor.
2. If the floor is uneven, the foot feel of the floor is of course not good. If problems are found on the day of paving, you can use quick-drying powder to wipe out the uneven areas. This will have a certain effect. This is only a stopgap measure. It is best to make the ground itself relatively flat.
3. After the floor is cleaned, lay the moisture-proof layer first to prevent the floor from getting damp in the future. The moisture-proof layer should be flat, the joints should be close together, and glued together with transparent glue. Many workers will forget to bring the tape. You can buy it yourself for a few dollars per roll.
4. The glue for bonding the floor should be dedicated to the floor. The main function of the glue is to prevent water from entering in the future.
5. The next step is to lay the floor. When laying, place a short piece next to a long piece, so that the cross-laid floor can be bitten and not easily loosened. After the floor is put together, it must be tapped with tools.
6. After installing in a certain area, it is best to fix the installed floor with a waste board, and pry in with tools to make the floor completely bite.

7. The floor is laid and the next step is to install the layering. Generally, the floor is higher than the ground and the high and low pressure strips are used. The floor is as flat as the ground.

8. When installing the bead, be sure to bite the bead with the floor, and tighten the screws, otherwise the bead and the floor will be easily separated in the future.
