What is air duct fire board?

Air duct fireproof board is a kind of fireproof material specially used for ventilation or smoke exhaust duct in construction projects. Huachengxing air duct fireproof board is a new green building material with high stability. The main composition is composed of fiber, siliceous calcium mineral and refractory material, and its flame retardant material is rich, and its thermal conductivity is lower than that of glass, clay and ordinary concrete. In the strength is much higher than the traditional plasterboard, with high fire grade, no pollution, long life, convenient construction and other characteristics, is widely used in a variety of building fire prevention system.

Introduction to Products

I.Production process

Huacheng Xing wind pipe fire board is made of selected high quality fireproof quartz powder, flame retardant minerals (mica, perlite) supplemented by cement and a variety of additives as raw materials, with high quality refractory composite fiber and other mineral fibers as reinforcement materials, by advanced production technology molding, high pressure, high temperature, steam feeding and other special technology treatment.

Ii. Product features:

1, light and high strength: air pipe fire board structure is special, the weight is much lighter than ordinary concrete, clay brick, high flexural strength; Light weight, in strength is much higher than the traditional equivalent plasterboard. Especially when the air duct fire board is used as the smoke exhaust system under external pressure or the air exhaust and smoke exhaust system, it can play its characteristics of high strength, light weight, good extension and strong earthquake resistance.

2, fire retardant: Huacheng Xing air pipe fire board non-combustible performance up to A standard. After the installation of the fire board, it has superior stability and integrity, and has better fire resistance. Once a fire occurs, it can control the fire in the initial pipeline to achieve effective isolation. Because the flame retardant fiber material is inorganic, it does not burn itself, and will not emit toxic gas due to high temperature, it should give you more security, is a kind of prevention first, prevention is better than rescue fire theory!

3, convenient processing: Huacheng Xing air pipe fire board can be processed at will (planing, saw, nail, drill) can provide more design solutions!

4, suitable for bearing: high strength of air duct fire board to adapt to a certain wind load.

5, high durability: air pipe fire board belongs to inorganic silicon calcium material, not easy to aging weathering, and mildew anti-corrosion function is quite good, even in the water conditions are not easy to deformation, is a durable and high-performance building materials, the normal service life can be matched with the life of all kinds of buildings.

6, green building materials: air pipe fire board in the production process not only no pollution will not produce hazardous waste, it is a new type of pollution-free green building materials, no radioactivity and will not produce harmful substances because of the change of environmental temperature and humidity conditions.

7, economic and practical: the thin thickness and light weight of Huacheng Xing air pipe fire board make the pipeline construction more flexible, reduce the overall load of the pipeline, effectively shorten the construction period.

Iii. Scope of application

It is often used in self-supporting air duct, mesa, building interior and exterior wall, steel column and steel beam fire cladding, network floor and tunnel interior engineering siding, home decoration, industrial and commercial engineering ceiling and partition wall, etc. Construction unit, designer, construction unit can choose the product according to the specific situation of the project. Huacheng Xing wind pipe fire board is a special fireproof material, has been widely used in Beijing, Shijiazhuang, Hohhot, Baotou, Tianjin, Shanghai, Guangzhou, Xi 'an, Dalian and other first and second tier cities. Main specifications: 1220* 2440*9, 12mm If the customer needs other size, the enterprise can cut on behalf of the special specifications can be scheduled processing. If you have any technical problems, please contact us in time.

Iv. Installation method

Self-supporting fire board air duct: The structure of self-supporting fire board air duct is shown in (Figure 1), and the corner node is enlarged as shown in (Figure 2).

Fire protection cladding layer of metal air duct: The structure of metal air duct covered by fire protection board is shown in (Figure 3), and the node magnification is shown in (Figure 4). The U-shaped light steel keel is fixed on the outside of the metal air duct, and the fire board is connected with the U-shaped light steel keel.

Plate blanking and forming: the four face wall panels of rectangular fire proof board air duct shall be blanked according to the construction drawings, wind diameter size and plate thickness, and the plates at the bending pipe and variable diameter of air duct shall be blanked.

Plate specifications: 2440mm-1220mm, plate thickness 9mm, 12mm/15mm; Generally, the length of each section of the air duct is 1220mm according to the width of the plate. When the length of the air duct is less than or equal to 1220mm or the sum of the two sides of the air duct is less than or equal to 1220mm, the air duct can be made of 2440mm according to the length of the plate to reduce the interface of the pipe section.

Try to avoid splicing of air duct plates. When splicing is required, it shall be according to the requirements (FIG. 5), and strengthening measures shall be taken for air duct at the splicing place.
