Since the beginning of this year, the weather has been dry and fires have occurred frequently, especially in high-rise buildings, where rescue has become difficult. This has raised people's awareness and requirements for building fire safety to a new level, and people are paying more and more attention to fireproof panels.
What is fireproof board
Fireproof board is a new type of environmentally friendly board, commonly known as fire-resistant board. It is not really fireproof, but it is difficult to burn and can play a fireproof role to a certain extent.
Fireproof board is a fire-resistant building material used for surface decoration. It is made of multiple layers of kraft paper impregnated with phenolic resin and a layer of decorative paper impregnated with melamine, which are pressed under high temperature and high pressure. It is abbreviated as HPL and has a thickness of 0.2-1.6mm.
It is easy to use. You only need to press the fireproof board and the board tightly together. The manufacturer can flexibly cut it according to the size and color required and use it as a veneer.
Standards and requirements for fireproof boards
As China and other countries in the world pay more and more attention to building fire protection, the national fire department requires enterprises and institutions to conduct mandatory fire inspections before completion and operation. Among them, the fire protection level of building materials is an important part of electrical fire inspections.
my country's national standard GB8624-97 divides the combustion performance of building materials into four levels:
A-level
Non-combustible building materials: materials that hardly burn.
Level B1
Flame-retardant building materials: Flame-retardant materials have good flame retardancy. They are difficult to catch fire when exposed to open flames or high temperatures in the air, are unlikely to spread quickly, and stop burning immediately when the fire source is removed.
Level B2
Combustible building materials: Combustible materials have a certain flame retardant effect. When exposed to open flames or high temperatures in the air, they will immediately catch fire and burn, which can easily lead to the spread of fire. For example, wooden columns, wooden roof frames, wooden beams, wooden stairs, etc.
B3 level
Flammable building materials: no flame retardant effect, extremely easy to burn, and high fire risk.
The pain point of high-end decoration - lack of materials
Wood-based combustible organic boards have been strictly restricted for use in construction projects, while inorganic fire-resistant boards such as paper-faced gypsum boards and calcium silicate boards face certain resistance to promotion because they cannot meet the construction and application requirements of construction projects in terms of strength, toughness, water resistance, and secondary processing performance.
At present, the fireproof boards on the market can generally only reach the B1 fire protection level, which can be used in ordinary home decoration. However, for public places such as hotels, conference halls, KTVs, etc., once a fire occurs, the consequences will be serious. Therefore, the fire protection requirements are more stringent, and almost all building materials must reach A-level fire protection.
In recent years, the log style has become popular, with theme hotels and theme KTVs becoming increasingly popular. These decoration styles are leaning towards a natural and rustic feel, with walls and ceilings ditching the straight, flat melamine-impregnated paper in favor of vibrantly patterned veneer. However, veneer is a combustible material and therefore would not meet fire safety inspection requirements.
The market welcomes new materials
Is there a material that can solve the problem of substandard fire protection while also allowing for natural-textured veneer decoration?
Recently, a new material has come into our sight. This material is made by covering the back of natural veneer with aluminum foil. While retaining the texture of the veneer, it improves performance in all aspects.
Class A fire protection
The veneer and aluminum foil are bonded together through a special composite process and used as a veneer material when covered on the surface of building panels to meet Class A fire protection requirements.
Super ductility
As we all know, wood veneer, as a natural material, is inherently brittle and prone to cracking or even breaking when bent. However, veneer laminated with aluminum foil has greatly enhanced ductility, allowing it to bend and fold, making it suitable for curved walls and even right-angle bends.
The emergence of veneer fireproof boards has brought new choices for high-end decoration in public places. Fireproof boards are no longer limited to monotonous melamine impregnated paper, but can also have beautiful and varied veneer textures.
Fireproof panels can be used in many places, such as hotel lobby wall guardrails, theater wall and ceiling decorations, libraries, conference room sound-absorbing panels, etc.
Manufacturers can directly purchase aluminum foil veneer and process it themselves, or they can buy veneer-treated veneer fireproof boards.
