Smoke and Exhaust Rock Wool Board

Smoke and Exhaust Rock Wool Board is a professional functional rock wool product independently developed by Hebei Huashuo Xingye Thermal Insulation Building Materials Co., Ltd., tailored for the smoke prevention and exhaust system of buildings and industrial facilities. Based on the advanced production process of molten rock mineral centrifugal spinning, curing and precision cutting, the product is optimized for the high-temperature, smoke and heat insulation requirements of smoke prevention and exhaust pipelines and supporting structures, while retaining all the excellent performance of traditional rock wool boards. It is a key supporting material for ensuring the safe operation of smoke prevention and exhaust systems in high-rise buildings, commercial complexes, industrial plants and public facilities.

Core Product Characteristics

High-Temperature Resistance & Fire Safety for Smoke Exhaust

As the core performance of the product, it inherits the non-combustible property of rock wool materials and can withstand high temperatures up to 600℃, with a high thermal load shrinkage temperature. In the smoke prevention and exhaust system, it can stably resist the high temperature of smoke and hot air during fire, effectively block heat transfer, prevent the pipeline and supporting structure from deformation and damage due to high temperature, and ensure the unobstructed smoke exhaust channel to provide a guarantee for fire evacuation and fire fighting. It will not produce toxic smoke or combustible substances at high temperatures, avoiding secondary pollution and danger caused by material combustion.

Excellent Thermal Insulation & Heat Isolation

It has an extremely low thermal conductivity and a scientifically designed density (in line with the 80-180kg/m³ density range of rock wool boards, customizable for special specifications of smoke exhaust systems). It can effectively isolate the high temperature of the smoke and exhaust pipeline from the external environment, prevent the high temperature from spreading to the building structure and indoor space, avoid fire spread and thermal damage to the building, and also reduce the heat loss of the system in normal use, improving the operation efficiency of the smoke prevention and exhaust system.

High Structural Strength & Stable Performance

The product is optimized for the installation and use characteristics of smoke prevention and exhaust pipelines, with high compressive and tensile strength. It can withstand the vibration and external pressure during the operation of the smoke exhaust system without deformation and falling off, and ensure the close combination with the pipeline structure. Its fiber distribution is uniform, the slag ball content is strictly controlled in accordance with high standards, and it can maintain stable physical and mechanical properties for a long time in the cyclic environment of high temperature and normal temperature, with strong durability.

Superior Water and Moisture Resistance

It has a high hydrophobic rate and extremely low volume water absorption. In the actual application of building smoke prevention and exhaust systems, it can resist the moisture and condensation water in the air and pipeline, avoid performance degradation such as thermal insulation decline caused by water absorption, and prevent the board from mildew and corrosion due to dampness. It can maintain excellent performance in humid environments such as basements, underground garages and kitchen smoke exhaust pipelines, and extend the service life of the smoke prevention and exhaust system.

Good Chemical Stability & Environmental Protection

The product has excellent resistance to acid and alkali chemical corrosion, and will not react with oil fume, corrosive gas and other substances in the smoke exhaust pipeline (especially suitable for commercial kitchen smoke exhaust systems), ensuring no performance attenuation and structural damage. It is a green and environmental protection material without formaldehyde release, no harmful gas emission during production and use, in line with national environmental protection and building health standards, and will not cause air pollution to the building interior and surrounding environment.

Matching Breathability & Sound Absorption

It retains the porous structure of rock wool materials, with good air permeability, which can reduce the risk of condensation water formation in the pipeline and protect the smoke exhaust pipeline structure from moisture damage. At the same time, it has excellent sound absorption and noise reduction performance, which can effectively absorb the noise generated by the smoke exhaust fan and the flow of smoke and air in the pipeline, reduce the noise pollution of the smoke prevention and exhaust system to the building interior and external environment, and optimize the acoustic environment of the building.

Main Application Scenarios

Building Smoke Prevention and Exhaust Pipelines

Widely used as the core thermal insulation and fireproof layer of smoke exhaust pipelines in high-rise residential buildings, commercial complexes, shopping malls, hotels and office buildings, suitable for both indoor and outdoor smoke exhaust pipeline systems, and can be matched with various pipeline structures for installation.

Commercial Kitchen Exhaust Pipelines

Specially applicable to the oil fume and smoke exhaust pipelines of commercial kitchens in shopping malls, hotels, catering plazas and other places, it can resist the high temperature of oil fume and the corrosion of oil substances, and achieve the effects of heat insulation, fire prevention and noise reduction.

Industrial Plant Smoke and Dust Exhaust Systems

Used for the thermal insulation and fireproof protection of smoke and dust exhaust pipelines and supporting structures in industrial plants such as metallurgy, chemical industry and machinery manufacturing, it can withstand the high temperature of industrial smoke and dust and the erosion of slight corrosive gas, ensuring the safe operation of the industrial exhaust system.

Public Facility Smoke Prevention and Exhaust Projects

Applied to the smoke prevention and exhaust systems of key public facilities such as stadiums, transportation hubs (railway stations, airports), hospitals and kindergartens, which have high requirements for fire safety and environmental protection, and provide reliable fireproof and thermal insulation protection for the smoke exhaust system of public places with large flow of people.

Quality Control & Installation Matching

Strict Quality Detection

The product strictly complies with national and industrial standards for rock wool products and the special technical requirements of building smoke prevention and exhaust systems. All core indicators including organic content, slag ball content, fiber diameter, hydrophobic rate, compressive strength, tensile strength, thermal conductivity and thermal load shrinkage temperature have passed professional detection (combustion method, screening test, microscope detection, high-temperature furnace test, etc.), ensuring stable and reliable performance under high-temperature smoke exhaust working conditions.

Easy Installation & Good Compatibility

It can be installed by pasting, mechanical fixing and other methods, and is highly compatible with metal, plastic and other common smoke exhaust pipeline materials. It can be customized into special specifications (thickness, width, length) according to the size of the smoke prevention and exhaust pipeline, ensuring the close fit between the board and the pipeline, and giving full play to the fireproof, thermal insulation and noise reduction effects.
