Cement Prefabricated House Kitchen
The cement prefabricated flue in the cement prefabricated house kitchen is a dedicated exhaust duct for residential kitchens, made primarily of 32.5# Portland cement through mechanical forming processes. It features a stable structure and diverse functions, serving as a core component of the exhaust system in modern high-rise residential buildings.

Raw Materials and Manufacturing Process
The cement prefabricated flue uses 32.5# Portland cement as its primary raw material, reinforced with 22#-26# galvanized steel wire mesh to enhance structural strength. Its production employs the vibration casting forming process, where mechanical vibration ensures uniform filling of the mold by the cement slurry, resulting in a pipe with uniform wall thickness. After forming, it undergoes steam curing to accelerate the cement hydration reaction, achieving the designed strength and forming a finished product with a smooth inner wall and a vertical load-bearing capacity of ≥90KN. This process allows for adjustable wall thickness (typically a standard thickness of 5cm) to meet different architectural requirements.
Performance Characteristics
- Physical Properties: The design with a standard wall thickness of 5cm is based on the low-temperature conditions of kitchen flue gases, eliminating the need for excessively thick pipe walls to meet safety requirements. The outer wall is often supplemented with insulation materials and protective layers to further enhance thermal insulation and protection. It has a compressive strength of up to 10MPa and high vertical load-bearing capacity, capable of withstanding building structural deformations or external pressures.
- Functional Advantages: It possesses characteristics such as lightweight, corrosion resistance, excellent sound insulation, high-temperature resistance, and flame retardancy. The smooth inner wall reduces flue gas flow resistance and lowers noise levels; high-temperature resistance and flame retardancy ensure that the flue does not become a channel for fire spread during fires.
- Construction Convenience: Prefabricated production allows for simple and efficient on-site installation, with high material stability, ensuring long-term stable exhaust performance and reducing post-maintenance costs.
Installation and Design Requirements
As a core component of the high-rise residential exhaust system, the cement prefabricated flue must be paired with fire-resistant variable-pressure exhaust ducts and other anti-backflow designs to prevent flue gas reversal. Additionally, aerodynamic structural optimization (such as variable cross-section designs) is employed to enhance exhaust efficiency and reduce airflow turbulence. Installation must strictly adhere to specifications to ensure the flue's verticality and connection tightness, avoiding air leakage or deformation risks.
Application Scenarios
It is primarily used in spaces requiring centralized exhaust, such as residential kitchens and bathrooms, especially suitable for high-rise buildings. Its standardized production and modular installation characteristics make it an efficient and safe exhaust solution in modern architecture.
