Product Description

WEIDA AAC Production Line:

1.Weda Machinery Co. ,Ltd was renamed as Shandong Weda Environmental Protection Machinery in 2019(founded in 1984) It is located in Linyi of Shandong Province, which is the logistics capital of China. With an investmentof 20 million USD and an area of 53,000 M2, it is a high-starting technology-oriented enterprise with advanced processingequipment, superb professional skills and rich manufacturing experience, the company has 18 professional and seniortechnical personnel and more than 350 professional and technical workers of various kinds, the company has 117 setsof precision processing machine tools and advanced inspection and testing equipment and a large number of precisionprocessing and advanced inspection, testing and debugging equipment, Our main product are:Concrete block machine,AAC block machine,concrete pipe making machine and concrete pole making machine.

1. AAC(Aerated Autoclaved Concrete Block Machine line)introduce
(1). introduce
Areated concrete brick (light brick ) is the light and porous buidling material. It has light keeping temperature cant burn and other advantages . it can be made into many kinds of bricks (for example : 600×200×100,600×150×100 , 600×300×200, 600×200×150 ) ,they could be used industry building and common building . they are more and more popular in the world .in the future ,they will replace the Clay brick completely .

(2).Areated concrete common conception
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%.
(3). Advantages
light weight
Areated concrete density is usually 400-700kg/m³,(according the market ti produce ),same as 1/3 of clay brick and 1/5 common concrete.So use the Light brick can reduce the weight of the build more ,and also reduce the beam of roof and pillar press best . then you can see ,it can save the material and cost ,it also fighting shaking .
keeping temperature
It has many are porous ,the delivery hearting coefficient is 0.9-0.22W/(mk),the same as 1/4 or 1/5 of clay brick ,so it is best materials now in the world .
have many kinds material ,have lowest waste
Main Material :A:sand/ Flyash 65-70% B:cement 12-15% C:Lime powder 12-15% D: Gypsum 3-5% E: Aluminum 0.5kg/m3 aac block
