Product Description

The Profile of our factory:

ShanDong SUNITE Machinery Group Co., Ltd. is a Chinese manufacturer of dedicated machinery for construction blocks and panels. Our company offers complete production lines for premium building components such as the autoclaved sand-lime brick, autoclaved aerated concrete block, and autoclaved aerated concrete / autoclaved lightweight concrete panel. Additionally, we provide various types of pressure vessels and block-making machines. By choosing SUNITE, customers can enjoy professional benefits with our dedicated services for design, installation, layout planning, technology transfer, and production guidance.




The Production Process Of Autoclaved Aerated Concrete Block:

1.Raw material storage
Flyash, sand, cement, lime, gypsum and aluminum powder should be stored separately in the corresponding stock yard. Then they will be disposed separately and transported to each work section when used.
2.Raw material disposed
Flyash and sand will be transported into the wet ball mill by the conveyor belt. Afterwards by slurry pump the slurry will be transported into slurry tank.
3.Batching, mixing and pouring
The lime and cement will be transported successively by the screw conveyor into automatic weigher for weighs, and the slurry will be transported by the slurry pump into automatic weigher for weighs. Afte weighing the powder and slurry will be transported into the mixer for uniformity and pouring into the mould box.
4.Curing, Cutting
The slurry which be poured into the mould box will preharden in the curing room which temperature is 40-50 degrees in one or three hours. When the body meets hardness of being cut, it will be transported with the mould box by reversal crane into the cutting cart. Then it will move with the cutting cart for level and vertical cutting.
5.Autoclaved and Finished product
The cut body will be putted on marshalling site by the crane. The marshalling body will be transported into the autoclaved kettle by the hauling engine or mobile windlass for 8-10 hours maintenance. Afterwards the finished products will be pulled away from the the autoclaved kettle by the hauling engine, with separating and packing they transported into stock by forklift.

AAC Advantages:

1.Lightweight: Porosity achieve 70% to 85%, volume density is generally 500-900kg/m3, as 1/5 of general concrete brick,the 1/4of clay brick, the 1/3 of hollow brick, and similar with wood can float in water. It can reduce building weight, reduction in the cost of integrated building,moreover,prolong building's life.
2.Fireproof: Most of the major raw materials is inorganic materials, so it has good fire resistance, and do not emit harmful gases when meet fire. Fire 650 degrees, as a refractory material, the thick up of 100 mm walls can reach to 4 hours fire resistance, 300mm thick up wall can reach to 9 hours fire resistance.
3.Sound insulation: Due to a unique porous structure, so it has a sound absorption capacity. The sound absorption capacity can reach of 100mm thick wall up to 41 db.
4.Insulation: As the material inside has a large numbers of the pores and porous, which has a good thermal insulation properties. The Thermal conductivity is 0.11-0.16W/MK, as 1/4-1/5 of brick. Typically, the insulation effect of 20cm thick aerated concrete wall is equivalent to 49cm thick solid brick walls ordinary.
5.Permeability: Result of material by the composition of many independent small pores, the moisture absorption is slow, in the volume of absorbent is 5 times of clay saturation do. When used in the bathroom, the wall can be treated to interface directly paste tiles.
6.Anti-seismic: The same building structure, improve the two seismic than the brick level.
7.Green: Manufacturing, transportation, all use the process of non-pollution, to protect arable land, saving energy, is one kind of a green building material.
8.Durability: material strength is stable, in the specimens tested after one year of atmospheric exposure; the intensity increased by 25%, and remained stable even after ten years.
9.High workability: it has good machinability, can be sawed, planed, drilled, nailed, and available appropriate as bonding of adhesive material, so create favorable conditions for building construction.
10.Economies: An integrated lower cost than using more than 5% of solid clay bricks, and can increase the usable area, greatly enhance the utilization of floor space.
