The aac block autoclave is a crucial core component of the AAC (Autoclaved Aerated Concrete) production line. It is responsible for the final high-pressure steam curing process, transforming pre-cured green cakes into fully hardened, high-strength AAC blocks or panels.
Product Performance: Core Role in the Autoclaved Aerated Concrete Production Line
The aac block autoclave equipment is a crucial core component of the autoclaved aerated concrete production line. It is responsible for the final high-pressure steam curing process, transforming pre-cured green cakes into fully hardened, high-strength AAC blocks or panels.
By subjecting the green bodies to precise temperature and pressure conditions, the aac block autoclave initiates a hydrothermal chemical reaction (mainly the formation of tobermorite crystals), which provides the AAC products with:
● High compressive strength
● Dimensional stability
● Excellent thermal insulation and durability
This process is essential for achieving the final physical and mechanical properties required for AAC building materials.
Working Principle
The autoclaving process follows a controlled, multi-stage thermal curing cycle, typically lasting 8–12 hours, depending on the product type and volume. The general working steps include:
● Loading: Cut and pre-cured AAC cakes (on steam-curing trolleys) are moved into the aac block autoclave chamber through a rail system.
● Sealing & Pressurization: Once sealed, the aac block autoclave equipment is filled with saturated steam, gradually increasing both temperature (180–200°C) and pressure (1.0–1.3 MPa).
● Isothermal Soaking: The system maintains a steady high-pressure steam environment, allowing hydration and crystallization reactions to occur, converting calcium-containing compounds and silica into tobermorite.
● Cooling & Decompression: After the reaction period, steam is gradually released, and the temperature is reduced to ambient levels to ensure product stability.
● Unloading: Cured AAC products are then unloaded for packaging and dispatch.
