How good is the fire performance of flame retardant board?

Types of flame retardant boards. Flame retardant board is a kind of flame retardant board that is more resistant to the external environment, and its main role is the advantages of weather resistance, durability, steam treatment, high temperature resistance and boiling water resistance. Flame retardant board is a relatively moisture-resistant flame retardant board, which can withstand a short period of immersion in cold water, and can be used at room temperature indoors, and is generally used for furniture manufacturing and general construction purposes.

Flame retardant board is a water-resistant flame retardant board that can withstand short hot water impregnation and long cold water impregnation. Flame retardant board is a false oh not moisture-resistant flame retardant board, generally used in the north of the dry indoor use, mainly used for food and general purpose flame retardant board materials are ash, basswood, birch, poplar, elm, etc. Performance characteristics of flame retardant board.

Classification of flame retardant plywood fire ratings. Fire rating A: Class A is a non-combustible material, and the flame retardant grade of Class A is high, and it is also quite expensive.

Fire Rating B: Class B flame retardant grade is a flame-retardant material, which is used in general public places to decorate. Fire rating B1:

B1 grade is a non-flammable material, it is combustible, but it is not easy to burn, and it has a certain fire prevention effect in terms of fire retardant. This kind of board is generally used in low-end public places. Through the introduction of the above content, I have mastered the fire rating of flame retardant board, and I hope these contents will be helpful to you.

According to the "National Wood-based Panel Quality Supervision and Inspection" GB18580-2001 standard: chemical performance indicators are: formaldehyde emission E grade, E1 grade, E2 grade, etc.

According to the technical indicators of wood-based panel products, its physical properties are classified into three grades: excellent products, first-class products and qualified products. According to GB8624-1997 "Classification of Combustion Performance of Building Materials and Products", it is divided into: Class A non-combustible materials

Class A homogeneous material and Class A composite (sandwich) material; Class B combustible materials: B1 materials, B2 materials and B3 materials. According to GB8624-2006 "Classification of Combustion Performance of Building Materials and Products", it is divided into:

Class A1, Class A2, Class B, Class C, Class D, Class E, Class F. According to the national regulations, generally only B grade or C grade plates are sold, for B1 grade plates, it is recommended that customers choose C grade or B grade according to the requirements of the Ministry of Public Security. <>

Advantages of flame retardant board:

1. First of all, the flame retardant board has the ability to prevent the spread of fire and win valuable time for escaping the fire scene. Just because a flame retardant doesn't mean it doesn't burn, it just stops the fire from spreading quickly.

2. The flame retardant board is processed on the basis of plywood, which is light in weight, easy to process, convenient in construction and reduces costs.

3. The flame retardant board has good structural strength and strong bending resistance.

Disadvantages of flame retardant board:

1. Flame retardant board will produce toxic gas during combustion. The millennium boat flame retardant board adopts advanced flame retardant, which greatly reduces the production of toxic gases in the fire.

2. After the flame retardant board is treated with flame retardant, it will have a certain impact on the gluing strength of the board.

Flame retardant board working principle:

1. Flame retardant of the substrate: the selection of flame retardant effect is long-lasting, good loss resistance, waterproof and moisture-resistant environmentally friendly flame retardant, after the treatment of the substrate of the board under special conditions, the flame retardant and the wood fiber are fully combined, in the process of combustion, the flame retardant board can effectively dilute the combustible gas, isolate the air and the fire source, change the wood cracking process when it is not burned, control the burning trend and process of the floor, and finally achieve the purpose of flame retardant.

2. Flame retardant on the surface and bottom layer: The surface adopts patented technology, and some inorganic tempered materials are added to the surface layer, so it can increase the impact resistance and wear resistance of the floor at the same time, and make the floor have a different general flame retardant effect; And the bottom layer is added with a fireproof board setting, which can not only be waterproof and moisture-proof, but also fireproof and flame-retardant.

In today's home decoration, we generally use a variety of boards, and flame retardant board is also one of the choices of consumers. Of course, the use of plates is very foreign to many friends who want to decorate. Today, let's take a look at the flame retardant board and see the advantages and disadvantages of the flame retardant board.

1. Health and environmental protection is a good advantage of flame retardant board, because flame retardant board in the processing project, due to the integrity of the wood, so the use of more liquid glue can be avoided in the processing process, as well as the common decorative pollution source formaldehyde lurking in the liquid glue, from this situation, flame retardant board is more environmentally friendly and healthy. 2. Flame retardant board has good anti-corrosion performance: because the surface layer of flame retardant board is made of high-quality wood after several processes of drying, degreasing, health and slicing, there should be no rot, dead knots, wormholes, crack defects such as peeling on the surface, but for small sliding, the color difference can not be too harsh, because it is the natural characteristics of wood.

In some places, the moisture content of flame retardant board is usually 5 -14. 3. The above is an introduction to several advantages, but flame retardant board also has corresponding disadvantages: multi-layer board is suitable for use as a variety of furniture, and the environmental protection effect is better than that of particleboard.

However, the blister of the flame retardant board cannot be repaired after it is damaged, and the feeling of the foot is also poor. Compared to other materials, flame retardant boards need to be taken care of. Attention should also be paid to waterproof, scald-proof, and sun-proof; The resources of flame retardant boards are getting less and less, and the ** is getting higher and higher, and it is easy to be deformed by the environment.

When a fire breaks out indoors, flame retardant boards can play a role in inhibiting the spread of fire and reducing the heat of the fire, so as to win valuable escape time for people.

There are many types of flame retardant boards on the market, and the fire rating standards of each flame retardant board are different, Class A: non-combustible board: will not burn, will not cause open flames.

B1 grade: refractory plate: has a good flame retardant effect.

If there is an open flame in the air or in a high temperature state, it is generally difficult to catch fire, and even if it is on fire, the fire is not easy to spread, and when the fire source is removed, the fire will stop quickly. Class B2: Combustible Plate:

It has a certain flame retardant effect. If it encounters an open flame or a high temperature in the air, it will burn quickly and cause the fire to spread quickly. Level B3:

Easy to burn the plate: It does not have any flame retardant effect, it is very easy to be burned, and once a fire occurs, it is very dangerous.

Hean Crown, high-performance flame retardant board, layer upon layer of flame retardant, layer upon layer of safety, mildew and mothproof, in line with the inspection requirements of the National Center for Quality Supervision and Inspection of Fireproof Building Materials, and the combustion performance meets the inspection requirements of the mandatory national standard GB 20286-2006 "Combustion Performance Requirements and Labels for Flame Retardant Products and Components in Public Places".

Advantages of flame retardant board:

1.When the flame retardant board is primed on the original wall (cement sand wall), the overall flatness error is not more than 3mm, and it can be directly fixed with steel row nails, which is easy to construct.

2.Compared with calcium silicate board, flame retardant board is relatively light, cutting will not cause great pollution, the material is lightweight, the nail holding force is good, and it can hang paintings, chandeliers, etc.

Cons: 1In the event of a fire on a flame retardant board, it is not that it will not burn, but it will be delayed, and it will emit toxic gases.

2.The plate will be thermally expanded and contracted when exposed to moisture or exposure, and its stability is not as good as that of calcium silicate board, and its service life is not as long as that of calcium silicate board.

Flame retardant board can be widely used in hotels, hotels, conference centers, libraries, leisure and entertainment venues, shopping malls, medical structures, office buildings and other building decoration projects, as well as high-end residential building decoration and furniture manufacturing projects.

Due to its flame retardancy, smoke suppression, and environmental protection, the flame retardant board is widely used in building decoration.

In the past, 90% of flame retardant boards were used in commercial real estate, but now flame retardant boards are more and more valued by people, and its use range is more extensive, and it can often be seen in interior decoration.

In the application, it can be comprehensively considered according to its flammability and **.

Scope of recommendation: Steel-making plants, blast furnace operations, and other plants with high requirements for FRP lighting panels (Leno Building Materials).

Flame retardant board has a wide range of uses:

Building decoration materials (acoustic panels, wall cladding).

Wooden fire-rated door frame panels or door leaf panels.

Flame retardant flooring substrate.

Flame retardant wood furniture.

Locomotives, interior cleats or finishing materials.

By definition, flame retardant boards have a wider range. Flame retardant materials, as long as they meet the corresponding national standards, such as GB8624 standards, can be called flame retardant materials and non-combustible materials; The flame retardant board, from the standard point of view, is only one of them.

As far as what appears on the market at the moment, it seems that you are talking about the same kind of plate.

As the city's high-rise buildings rise from the ground, the difficulty of small parties has also increased greatly. The decoration of the dust, not only to consider the performance of the plate, formaldehyde emissions, but also to consider whether it has a certain flame retardant level, let's find out together.

Flame retardant board, also known as flame retardant board, flame retardant MDF, flame retardant plywood, etc., is a wood-based board made by adding flame retardant to the board production line through a complex process in the production process of wood-based panels. Flame retardant board has the advantages of durability and high temperature resistance.

Flame retardant board fire rating standard

Flame retardant board fire rating A:

Class A is a non-combustible material, and the flame retardant level of Class A is very high, and it is also quite expensive.

Flame retardant board fire rating B1:

The B1 flame retardant grade is a flame-retardant material, and generally high-end public places are decorated with this material.

Flame retardant board fire rating B2:

B2 grade is a non-flammable material, it is combustible, but it is not easy to burn, and it has a certain fire prevention effect in terms of fire retardant. This kind of board is generally used in low-end public places.

Flame retardant board fire rating B3:

It is a flammable board, which does not have a flame retardant effect and is also very flammable.

Flame retardant board and fireproof board are two common anti-distress building materials, and they have some differences in fire performance. Here's a closer look at them:

1.Fire-resistant board: Flame retardant board is a material that has the property of preventing the spread of flames.

It is usually made from a mixture of wood fibers, cement, fillers, and other additives. The main features of flame retardant board are as follows:

The flame retardant performance is good, which can effectively slow down the spread of fire.

High temperature resistance, able to resist high temperature burning for a certain period of time.

It has certain strength and durability, and is suitable for building structures such as walls, ceilings, and partitions.

2.Fireproof board: Fireproof board is a material that can effectively prevent the spread of fire. It usually consists of inorganic materials, fibrous materials, and adhesives. The main features of fireproof board are as follows:

Excellent fire performance, which can effectively resist the burning and spread of flames.

High temperature resistance, able to maintain a certain stability in high temperature environment.

It has high strength and durability, and is suitable for places with high requirements such as building exterior walls and fire doors.

In summary, flame retardant board is mainly used to slow down the spread of fire, while fireproof board can effectively prevent the occurrence and spread of fire. Because of this, when choosing to use, it is necessary to determine which material to use according to the specific use environment and needs. At the same time, the relevant building regulations and fire safety standards should be followed to ensure the fire safety of the building.

The difference between flame retardant board and fireproof board is due to the different materials and the application of the two. For example, flame retardant board, it can be directly used to make various furniture, while bridge fire destroyer board can be used for the production of cabinets, but in practical application is not suitable for other furniture, such as wardrobes and so on. In fact, fireproof board is not that it can be fireproof, in fact, it will also burn, but its fire resistance is much higher than that of other materials, and it can last longer in a high-temperature environment.

When such an accident happens, the shelter can provide more time and opportunities for people to escape. In addition to its fire-resistant characteristics, fireproof board can also be used as a decorative material, mainly because it has very bright colors and rich textures. Moreover, it is light and high-strength, sound absorption and sound insulation, green environmental protection, easy to process, economical and practical, etc., which are the inherent characteristics of fireproof board.

Fireproof board flame retardant board is different from fireproof board, it is made of wood chips or blocks after flame retardant treatment and glued together in the direction of adjacent layers of wood chip fibers perpendicular to each other to form three or more layers of plywood. Because flame retardant board is a wood material, it will have some inherent defects of natural wood compared with other fireproof materials, and its ignition point will be lower than that of other materials. However, the flame retardant board contained in it can release substances that hinder combustion in a high-temperature environment, such as non-flammable gases, such as Changze substances that quickly decompose wood fibers, and so on.
