Development and product characteristics of aerated concrete block
Aerated concrete block as an important part of wall materials innovation and building energy saving, is proved by fact as a kind of the ideal wall material substitute for clay brick after years of application, it has strong competitiveness in various wall materials. In national eleventh "five plan" our country clearly put forward the development of aerated concrete plate and an annual output of 100000 -- 300000 cubic aerated concrete block production line, autoclaved curing, mechanical cutting." because of the need for wall reform and the advantage of aerated concrete products, aerated concrete is a new light building materials developed in the recent ten years.

AUTOCLAVED AERATED CONCRETE PANELï¼?AACï¼? ALC/AAC panel
1. Light weight: Bulk density 425ï½?625kg/m³, Only for 1/4 concrete, 1/3 Clay brick, The weight of the building can be greatly reduced, and the design value is reduced too.
2. Fire resistance: 125mm AAC panel fire resistance can reach more than 4 hours, It is real fire prevention material in Grade A.50mm AAC panel can be met the fire protection requirements of steel structural members.
3. Anti crack: The shrinkage value of natural state is smaller than that of the clay brick, and the special technology is adopted to solve the problem of the quality of the slab cracks.
4. Thermal insulation: thermal insulation is only 0.11ï¼?B04ï¼?, It is a new type of building material that can meet the building energy saving more than 65% by a single wall.
5. Seismic resistance: Allowable inter layer deflection angle 1/150, When the special node is used to achieve 1/120, In the case of all the nodes, the panel will not fall off when the 1/20 is changed in the layerï¼?So that the anti-seismic effect is excellent.
6. Environmental protection: No radiation, Both the internal and external illumination coefficient are less than 0.1, is 1/4 of Fly ash board, Excellent sound insulation performance, 100mm AAC panelï¼?Double sides puttyï¼?could reach 40.8dB, The sound insulation effect of is similar with 200mm fly ash brick wall.
7. Bearing capacity of Autoclaved Aerated Concrete Panel: The plates are equipped with internal double layers, two-way mesh reinforcement, can produce wall panels, partition wall, floor decking, roof board, decorative board etc..
8. economical: Using AAC board as the wall material, can effectively improve the use of the building area, reduce the use of energy consumption, to achieve the national building energy efficiency standards. Under the same sound insulation and fire protection requirements, AAC plate thickness is the smallest, and don't required the tie column, waist beam and other auxiliary components, This can reduce the wall load, thereby reducing the cost of construction.
9. Extensive: Can be used for concrete structure, steel structure residential buildings, office buildings, building internal and external wall body, floor slab, roof panel, firewall, explosion-proof wall, structural steel beams and columns fire maintenance, soundproof walls, old buildings and renovation.
10. Convenience: Eliminating the traditional building blocks in the process of the type of work, such as Mixing, masonry, plastering, reinforcement, formwork and concrete etc. Just the plate installation workers can do all the work, Avoid the conflict of work and mutual restraint.
Aerated concrete density is usually 600-800kg/m3(according to the market in production), same as 1/3 of clay brick and 1/5 of common concrete, so use the light brick can reduce the weight of the building, and also reduce the beam of roof and pillar press, also you can see, it can save the material and costs,
Keep temperature.
It has many porous, the delivery hearting coefficient is 0.90.22W/MK, so it is the best materials in the world now, also many kinds of raw materials, have lowest waster materials, coal ash, sand waste mine materials stone dust and other silicon materials.
Raw material: Sand, fly ash, lime, gypsum, aluminum, cement and other aggregate.
3.The autoclaved aerated concrete block production line process:
(1).aerated concrete/aerated blocks raw material preparation and storage:
we will use jaw crusher, ball mill, bin and bucket elevator.
(2).Aerated concrete/aerated blocks Ingredients, mixing, pouring:
needs mixer, casting machine, screw conveyor, belt conveyor, batching system control , the aac
mould and so on.
(3).aerated block static stop maintenance.
(4).aerated block cutting section.
aac cutting machine/aerial tumbling cutting units is important.
(5).aerated block coding ,autoclaving and finished product.

Autoclave kettle is large pressure container by steaming the aerated concrete, sand lime brick and coal-dust brick. Also are widely used in other production projects which need steamng curing. Such as super-strength gypsum, insulation materials,rubber products, high strength glass and cement tubular pile and wood, medicine, chemical industry, etc.
(1)A single piece 16MNR steel plate is pressed to form the kettle cover, kettle cover flange and kettle body flange.
(2)Welding seam of the pressure parts all have heat treatment and strict nondestructive testing..
(3)Kettle door has manual and automatic opeartion according to customers demands.
(4)This kettle is opened very easily.
(5)This kettle occupies little space.
