Autocalve for AAC Block

AAC CUTTING MACHINE

Brief Introduction of  AAC production line

AAC production line is used to produce AAC block, AAC panel, which is a light weight, multi-cells new construction material; the features include lower density, heat insulation, processibility, fire and acoustical resistant properties.

AAC is made by AAC production line (AAC plant) and from silicon material (silica sand, or recycled flying ash) and calcium material (lime, cement), mixing with foaming additive (aluminum powder), batching with water, the reaction between aluminum and concrete causes microscopic hydrogen bubbles to form, expanding the concrete to about five times its original volume. It is made into the multi-cells silicate product by the processes of molding, pre-curing, cutting, evaporating and curing.

With abundant air cells and micro apertures inside the aerated brick, it has good performance of heat insulation and preservation. In addition, the most prominent advantage is its plasticity. Due to the lightness and the lower hardness, AAC units are available in numerous shapes and sizes according to practical construction applications.

HiSuccess can supply complete AAC production line from A to Z, high technology, good return.
