Common concrete density is usually 1600-2400kg/m3,but Areated concrete are 500kg/m3,600kg/m3,700kg/m3.It has not the big grain,main use silicon material (for example:coal ash,sand,stone dust and others ),through making the material small for example sand,they can be used directly if has enough degree of small (for example coal ash.Mixing calcium material lime cement water to a special slop,then add the aluminum dust and the additive.Make the aluminum dust and the special slop have a Chemical reflect.then produce Hydrogen to make the concrete slop to expanding or swell,foam.Next,put them into the curing room to concreting cutting steaming curing,last,there will bacome the light brick,the porous rate is 70-80%

2.The process of whole AAC line profile

3. Insurmountable Advantages of HONGFA MACHINE

Take ourAUTOCLAVE as a sample.

We are the only one company who has the ability to manufacture the autoclave by ourselves in Chinese AAC machine manufacturers.

NO.1 Material ,Special steel 16MNR for autoclave body and lid, thickness is about 20mm.

NO.2 Welding,Automatic welding machineto guarantee the welding seam closely connected.

NO.3 Detection,The X-ray detection to guarantee every seam without defect.

Especially the ultrasonic detection for the lid to intensify the flawness.

NO.4Triple detection,The final complete pressure test to guarantee whole body without defect

NO.5 Custom design pattern,we can design any diameter and length autoclave with great quality.
