Product Description

Detailed Product Description
High Precision AAC Sand Lime panel machine Lightweight Wall Panel  Fly Ash Slab
 
 
AAC slab/AAC panel:
 
Autoclaved Aerated Concrete panel/slab is also called ALC (Autoclaved Lightweight Concrete) panel/slab, which is steel mesh reinforced, lightweight and loadbearing.   
AAC slab can be used as external wall panel (exterior wall panel), internal wall panel (interior wall panel), partition wall panel, flooring, roofing, fence, cladding, curtain wall and facade etc. This kind of new building material has been well used in various kinds of buildings, such as public facilities, industrial constructions, civil housing, hospitals, hotels, apartments, villas, schools, stores, supermarkets etc. The AAC slab can replace traditional precast concrete and clay bricks very well. Also the panels can easily cut, drilled, screwed when installing with fast speed due lightweight and precast.
 
 
Superiority of product
 
1. the economy: can increase the construction area using the area, reduce the foundation cost, shorten the construction period, reduce the heating, air conditioning cost, achieve energy saving effect..
2. the construction is convenient: aerated concrete product size accurate, light weight, can greatly reduce the human material investment. The use of dry construction method when installing the plate is simple and efficient, and can shorten the construction period effectively.
3. environmental protection: in the production process, there is no pollution and hazardous waste generated. When used, there is no radioactive material and harmful gas, even in the high temperature and fire. Each independent micro bubble, so that aerated concrete products have a certain anti permeability, can prevent the penetration of water and gas
 
AAC panel machinery / AAC panel production line Production Process
 
First, the Fly Ash is mixed with water, and made Slurry in a slurry mixture. If Sand is used as a base material, we need a ball mill to grind the sand to fine power. The slurry making process is same sand. 
After Slurry is made, the slurry is stored in slurry storage tank, where the slurry is constantly agitated. Care is taken to run the slurry storage tank all the time, so that is never settles down the particles. 
Then a weigh batcher weighs the Slurry, lime, OPC, Gypsum and aluminum power in preset quantities, and mixes thoroughly. The mixture also pours the mix into the Mould carried by the mould cart. The full pouring of the mixture is just enough to fill around 50% of the mould. 
Then the mould is kept in a warm chamber for 2 hours, so that the aeration and the light initial setting takes place. Next process is de-molding process of the big panel, in which a sophisticated overhead hoist takes the mould, demoulds the panel. 
Next process is the level wire cutting of the panel, while the panel passes on the cutting trolley through the series of wires. This process follows a vertical wire cutting where is the panel remains stationary, and the cutter cuts the panel vertically. 
The final cut panels are Steam cured in autoclaves for 8 hours
