ALC board (also known as ACC board and NALC board), ALC is the abbreviation of Autoclaved Lightweight Concrete, and its Chinese name is autoclaved lightweight aerated concrete cement 、 quick lime 、 Gypsum As raw material, use Aluminium powder by foaming agent Porous silicate products obtained through a series of technological processes (batching, reinforcement, foaming, cutting) and high-temperature, high-pressure steam curing. It is suitable for residential, hotel, school, hospital, business office building and other civil and industrial buildings, and can also be used as a special material for shock absorption, sound insulation, sound absorption and handicrafts on both sides of expressway and subway. It can be divided into exterior wall panels, interior partition panels, floor panels, roof panels, special specification panels, etc. according to the use, and can be divided into light floor panels, ALC panels, ALC wall panels ALC board manufacturer, ALC floor, ALC partition board, ALC interior wall board, ALC exterior wall board, ACC partition board, NALC partition board, AAC board, ACC board, NALC board, NALC floor, NALC roof panel, etc.
The product specification is: width: 600mm, thickness: 50mm, 75mm, 100mm, 125mm, 150mm, 175mm, 200mm, length: 6000mm, and has the following characteristics:
one Lightweight
ALC is a lightweight porous material, with an absolute dry density generally less than 625kg/m ³. It can be used not only as partition board and roof panel, but also as external wall panel and floor slab. Its deadweight is about 1/4 of ordinary concrete and 1/3 of brick, which can effectively reduce the deadweight of buildings;
two Thermal insulation
The thermal conductivity of ALC board is only 0.13W/m · K, and its thermal insulation performance is 8 times that of ordinary concrete and 4 times that of solid brick masonry. It is a kind of thermal insulation enclosure structure material. On the premise of ensuring the necessary thermal insulation performance, ALC board wall is much thinner than walls and roofs made of other materials.
three Fire resistance
ALC board is an inorganic incombustible material with good volume thermal stability, slow heat transfer and good fire resistance. The fire resistance limit of 125mm thick board reaches more than 4 hours, exceeding the first grade fire resistance standard;
four Sound insulation
The internal microstructure of ALC products is composed of uniform and disconnected micro pores, which has the dual performance of sound insulation and sound absorption. The sound insulation of 100mm ALC board can reach 40.8dB; The average sound insulation capacity of 150mm thick ALC board is 45dB;
five Bearing capacity
As the filling material of the enclosure structure, ALC plate has the characteristics of light weight. The steel mesh meeting the design requirements is set inside the plate, which can bear the corresponding wind load, snow load and dynamic load;
six Seismic resistance
ALC plate is light in weight, and its scientific and reasonable installation node design and installation method make the plate have good following performance. The seismic performance test of aerated concrete exterior wall plate of steel structure residential system and low cycle repeated test were carried out in the seismic test center of Tongji University and Southeast University respectively, which proved that ALC plate has superior seismic performance;
seven , impermeability
The impermeability test carried out shows that it is 3 times higher than ordinary autoclaved aerated concrete. ALC products have excellent microstructure and holes are not interlinked with each other. Their softening coefficient Rw/R0 ≥ 0.88 after water saturation is far superior to ordinary autoclaved lightweight aerated concrete;
eight Environmental protection
The whole production process does not use harmful substances, and the finished products do not contain harmful substances. Water and materials are recycled. The construction and installation adopts the dry method, which has no impact or pollution on the environment. After testing, the internal exposure index of ALC material is only 0.2 (standard requirements ≤ 1.0), and the external exposure index is 0.1 (standard requirements ≤ 1.0). It is a green material without radioactivity and harmful substances.
