Classification of the combustion performance of sandwich panels
Grade standard: The fire performance grade of the main circuit board must be strictly in accordance with the core standard GB 8624 2012 appearing in the fire performance grades of building materials and goods, and the categories are A, B1, B2. Their residual heat moves to almost non-flammable, flammable, combustible and flammable materials at a rather high level.
My company offers a range of flammability grades to customers, except for one type of flammable flame, as follows:
Grade A (Non-combustible core)
Refractory solids that are almost non-combustible under standard conditions, with requirements for fire resistance stability, suitable for police traction in critical areas, data centers, and central computer rooms.
Grade B1
It has a sharp fire-extinguishing effect, and open flames can burn briefly in air or hot conditions. Even in a fire, it rarely spreads. Once the stove is removed, the flame will stop burning immediately. For mixed commercial complexes, industrial factories, exterior walls, etc.
B2 (Burning point)
Only at the main tearing point. An increase in fire risk or an increase in heat in the air can lead to hotter fires. Only in non-core areas with basic fire protection requirements, such as temporarily built halls, storage rooms and additional storage Spaces, is it recommended to use with caution.
Production process
The application scenarios of sandwich panels
Industrial parks
Firewalls, walls and interior decoration in factories such as electronics and chemical industries comply with the requirements of fire protection standards. All types of factories meet the requirements of 5,016 Thai baht. It can also be used on the walls of flammable bearings and roofs to reduce risks.
Business field
Mainly applied in interior decoration, architectural decoration, hotels, trading stations, etc. The fire resistance performance of these refractory materials complies with the regulations of fire limits, such as fire resistance limits and smoke poisoning. Lighters can also play a significant role in the damp conditions of garages, high fire protection requirements, and the stability of the lighter system.
Public facilities
In places such as schools and hospitals, the fire safety and hygiene of stoves are particularly important. They are not only crucial for life safety but also for people's comfort. Monitoring reports related to the arson call for transportation are available and can provide a complete report on the monitoring results, which will help the project carry out arson on the stands and prepare for safe sales.
Other motives
It is also applicable to the renovation and refurbishment of old buildings to enhance the overall firepower and appearance of the buildings. The shield and patterns comply with fire prevention regulations, and the decoration is pure. Even fire-resistant refractory materials can meet the requirements of special environments.

Maintenance and upkeep of sandwich panels
Daily cleaning
For fireproof aluminum-plastic composite panels indoors, a soft cloth dipped in clean water or neutral detergent can be used to gently wipe the surface to remove dust and stains. For outdoor panels, high-pressure water guns can be used for regular rinsing. During rinsing, the water pressure should not be too high to avoid damaging the panel coating.
Avoid collisions
During daily use, sharp objects should be prevented from colliding with the surface of the board to avoid scratches, depressions and other damages to the panel. If damage occurs accidentally, it should be repaired in time. Small scratches can be treated with special repair agents, while large damage requires the replacement of the board.
Regular inspection
Regularly inspect the installation and fixation of the panels, as well as the sealant at the joints. If problems such as loose screws or cracked sealant are found, they should be dealt with promptly to ensure the safe use and stable performance of the panels. It is generally recommended to have a check-up every six months.
Special case handling
If the surface of the board is stained with oil, chemicals or other stubborn stains that are difficult to clean, a dedicated cleaner should be used promptly for treatment to prevent the stains from adhering to the surface for a long time and causing corrosion to the panel. In the event of special circumstances such as fire or earthquake, professionals should be invited to conduct a comprehensive inspection of the boards to assess whether their performance has been affected. If necessary, they should be replaced.
FAQ
Q: What are the differences between B1 grade and A grade fire protection?
A: Grade A is non-combustible materials such as rock wool, but PU has better thermal insulation performance. Grade B1 has met the needs of most non-high-risk scenarios, and after modification, its flame retardancy is close to Grade A.
Q: Can it be used in open flame environments such as kitchens?
A: Fireproof rock wool boards should be used in the direct open flame area of the kitchen. This type can be used for adjacent partition walls, and a distance of ≥1.5m should be maintained.
Q: How to clean a dirty sandwich panel?
A: Wipe with clean water or neutral detergent. Do not use strong acids or alkalis.
Q: Will the insulation performance of fireproof PU boards decline due to flame-retardant treatment? Which is more suitable for cold storage, rock wool board or rock wool board?
A: Even after flame-retardant treatment, the insulation performance of fireproof PU boards will not decline. Its thermal conductivity can still be as low as ≤0.024W/(m · K), and compared with most traditional insulation materials, its insulation performance has significant advantages.
Q: Will the fire resistance of the board decline after years of use?
A: The flame retardant has strong stability. The flame retardant effect will decline by no more than 5% within 15 years of normal use. Aging test reports can be provided.
