Fire-retardant board ducts are a type of fire-resistant material specifically used for ventilation or smoke exhaust ducts in construction projects. New Long fire-retardant board ducts are a new type of green building material with high stability. They are primarily composed of fibers, silicate calcium minerals, and refractory materials, rich in flame-retardant substances, and have a thermal conductivity coefficient much lower than glass, clay, and ordinary concrete. The strength of the gypsum board is more than double that of standard gypsum board. They feature high fire resistance, non-pollution, long service life, and easy installation, making them widely used in the fire protection systems of various buildings.

       I. Manufacturing Process:New垄Fire-resistant duct boards are manufactured using high-quality fire-resistant quartz powder, flame-retardant minerals, supplemented with cement and various additives as raw materials. They are reinforced with high-quality refractory composite fibers and other mineral fibers, and are produced through special processes such as shaping, pressure application, high-temperature treatment, and steam curing.

       Section 2: Product Features:
       1. Lightweight with High Strength: The fire-resistant board duct has a unique structure, significantly lighter than common concrete or clay bricks, and boasts high flexural strength; it is much lighter than traditional gypsum board, with strength over twice as much. Particularly, the fire-resistant board duct, when used in engineering as a smoke exhaust system or a combined exhaust and smoke exhaust system that withstands external pressure, can fully utilize its characteristics of high strength, low self-weight, good elongation, and strong seismic resistance.
       2. Fire Retardant and Flame Retardant: Once installed, the fire-resistant panels offer superior stability and integrity, with excellent fire resistance. In the event of a fire, they can extinguish the flames at their initial stage, and ensure pipe isolation. As the flame-retardant fibers are inorganic materials, they are non-combustible and do not emit harmful gases at high temperatures. This represents a proactive fire prevention approach—prevention is better than cure!
       3. Easy to Process: Huachengxing fire-resistant board ducts can be processed freely (planed, sawed, nailed, drilled), offering more design options!
       4. Load-bearing Adaptability: The fire-resistant panel duct has high strength to accommodate certain wind load.
       5. High Durability: Fire-resistant board ducts are made of inorganic silicate calcium materials, which are not prone to aging and weathering. They also offer excellent anti-mold and anti-corrosion properties, and will not deform even when exposed to water. They are a durable and high-performance building material, with a normal service life that can match the lifespan of various types of buildings.
       6. Green Building Materials: The fireproof board ducts do not produce pollution waste during the production process, featuring the characteristics of new green building materials with zero pollution and no radioactive substances.

Fire-rated duct boards are commonly used in self-supporting ductwork, countertops, interior and exterior walls of buildings, fire-resistant coatings for steel columns and beams, network flooring, tunnels, and wall panels for indoor construction projects such as home decoration, ceiling suspended ceilings, and partition walls for commercial and industrial projects. Construction units, design units, and construction units can choose this product based on the specific project requirements. Fire-rated duct boards are a special type of fire-resistant material that is widely used in many cities. Main specifications: 1220*2440*9, 12mm. If customers require other sizes, the company can cut them on behalf of the customer, and special specifications can be arranged for processing.
