[Steam-free aerated block equipment] Basic description
Wide sources of raw materials, high waste rate and low cost. It uses fly ash, slag, sand, aeolian sand, stone powder with low soil content and tailing sand as the main raw materials (any one of these can be obtained locally, with high waste rate, low cost and high profit.< br/> , high technical content. One of its core technologies, the air-generating agent, is prepared in proportion from several readily available raw materials to achieve the effect of making bricks with air. The second core technology, the addition of reinforcing agents, greatly reduces the amount of cement. Reduce production costs, and make steam-free aerated blocks (bricks) reach the strength of autoclaved aerated blocks.
The process is simple and easy to operate. Use gas-generating agents and reinforcing agents to combine cement, fly ash, sand, etc. Material polymerization requires physical aeration and molding using special equipment and molds, without the need for autoclaving and curing.
There are no high requirements for production conditions. Simple work sheds can be used as workshops, and products are stored in the open air without the need for warehouses, which requires high quality of workers. The requirements are not high.
The investment can be large or small, and the production method is flexible. It can start with a small investment in a small number of molds, or it can be directly produced on a large scale, and it can be produced at a fixed site or moved to a different location.
, the technology has a wide range of uses. This technology can be used to transform molds to produce hollow blocks, insulation bricks, lightweight wall panels, insulation panels, and can also be used as lightweight concrete cast-in-place for roofs, walls, walls, floor heating, etc. In the field of thermal insulation.
【Steam-free air block equipment】Product features
High heat resistance. The fatal weakness of polystyrene foam is its low heat resistance temperature, which begins to decompose at ℃. When the temperature When it continues to rise, it will melt and shrink. The temperature of the floor heating hot water pipe is not constant, and sometimes exceeds ℃, which will cause the thermal decomposition of the polystyrene foam and cause the insulation to fail. The steam-free aerated block is Cement inorganic material has a heat resistance of up to ℃ and above. There is no thermal decomposition, so it has a longer service life and will not cause thermal insulation failure.
It is green and environmentally friendly, non-toxic and harmless. The steam-free aerated block does not contain any toxic substances The ingredients, foaming agents and various admixtures have no volatile harmful substances, which is beneficial to the indoor environment. However, polystyrene foam will release toxic styrene gas due to thermal decomposition. Therefore, using foam concrete is better than using polystyrene foam. Plastic is more environmentally friendly.
It has better strength than polystyrene foam. The compressive strength of polystyrene foam is only ~kg/foam concrete, and its compressive strength is better.
, lower cost of use. The current price of self-extinguishing polystyrene foam is about RMB/kg, while the total cost of foam concrete is only about RMB/kg/kg. The cost is lower than that of polystyrene foam, and it has Obvious economic advantages.
, Fast construction speed. Foam concrete can be poured and spread flat, no need to lay it one by one, its construction speed is faster than polystyrene foam board.
, No joints , reducing the heat loss caused by joints. Because polystyrene foam boards are laid one by one, there are many joints, which can easily form cold bridges or thermal bridges.
[Steam-free aerated block equipment] Scope of application
The steam-curing-free aerated block equipment is suitable for the interior and exterior walls of various civil buildings, public buildings and industrial plants, as well as the foundation of houses. It is a product that replaces sintered clay bricks and is a product that the country vigorously develops and applies. new wall materials.
