ALC wall panels are already well-known to everyone, and their superiority is highly appreciated by people. It is widely used in various frame structure buildings, as well as buildings such as factories. ALC wall panels also have high fire resistance and durability, and are also used as firewall panels. The ALC fire protection system can be widely used in various industrial factories, hotels, offices, and other buildings with strict fire protection requirements. Dry construction is convenient and fast, effectively shortening the construction period. After the wall is completed, its decoration method is simple and convenient. No additional wall insulation work is required. It is a very good fireproof building material.
1、 The Fireproof Technology of Alc Fireproof Board
ALC fireproof board is the abbreviation of autoclaved lightweight concrete, which is a kind of high-performance Autoclaved aerated concrete (ALC). ALC board is a porous concrete formed board (containing treated steel reinforcement) made from fly ash (or silica sand), cement, lime, and other main raw materials, and cured by high-pressure steam. ALC board can be used as both wall material, fireproof board, and roof panel. It is a new type of inorganic non combustible material with superior performance and green environmental protection. ALC boards have appeared in Europe for over forty years, with a history of production and application in regions such as Japan and Europe. At present, the production technology and equipment of domestic manufacturers mainly come from Japan and Germany.
2、 Product standard for Alc fireproof board
1. Product standards
Alc fireproof board is a type of alc board product, which has excellent fire resistance and fire resistance performance. As for the fire protection standard, there is no industry standard for the fireproof board (and its combination), but it should comply with the relevant requirements of incombustible materials in CECS200:2006 Technical Code for Fire Protection of Steel Structure of Buildings GB/T8624-1997 Grading Method for Burning Performance of Building Materials, GB6566 Class A Radionuclide Content of Building Materials, and GB50325 Code for Indoor Waste minimisation of Civil Building Engineering. But the Global Village Building Materials Company provides various certificates. Alc fireproof board has a series of formal certificates such as fire prevention reports and fire resistance reports, and is a legitimate enterprise.
2. Engineering standards
GB50016-2006 "Code for Fire Protection Design of Buildings"
GB50045-2005 "Code for Fire Protection Design of High rise Civil Buildings"
Through experiments, it has been proven that Alc board has strong fire resistance and fire resistance
3. Fire resistance
100mm thick alc fireproof board can reach 3.23 hours, and 125mm thick alc fireproof board can reach more than 4 hours;
4. Thermal insulation
The thermal conductivity of Alc fireproof board is 0.11, and its insulation effect of 125mm thick material can reach that of ordinary 370mm thick brick walls. It is a new type of building material that can achieve building energy efficiency of over 65% with a single material;
5. Environmental friendliness
No radiation, with an hourly exposure of 12Y μ/ h. Equivalent to the level on the outdoor grassland; New building materials that save more than 65% of building energy;
6. Convenience
ALC fireproof board is processed to a certain length after actual measurement on site, and is a factory prefabricated product with high accuracy. It can be planed, sawn, and drilled. Adopting dry operation, the installation is simple and the process is simple. It eliminates the traditional construction columns, waist beams, and plastering of walls, and directly applies putty, greatly shortening the construction period, improving speed and construction quality;
3、 Scope of use of Alc fireproof board
Alc fireproof board is a type of alc wall panel product, which is widely used in concrete structures, steel residential buildings, office buildings, factory buildings, internal and external walls, floors, roof panels, firewalls, explosion-proof walls, steel structure beams and columns for fire protection maintenance, sound insulation walls, and renovation of old buildings due to its fast construction speed;
Diversity: There are also 50mm thin plates and 37mm thin plates (which can be used as external wall insulation boards and fireproof boards);
Fastness: There are no traditional types of work such as mixing, masonry, plastering, steel reinforcement, formwork, concrete, etc. in the masonry process, and only the board installers can do it, avoiding conflicts and mutual constraints between different types of work.
4、 Alc fire resistance
Alc fireproof board is one of the alc wall panels, which has a series of characteristics such as fire resistance, fire resistance, lightweight, thermal insulation, and green environmental protection.
The fire resistance of Alc fireproof board is particularly good, and the application of very thin Alc board can meet the fire resistance requirements of building standards. The specific fire resistance range is as follows:
The 150mm thick Alc fireproof board has a fire resistance of up to 4 hours; 100mm thick alc fireproof board with a fire resistance of 3.42 hours; If used as an inner wall panel with a thickness of 50mm, the fire resistance is 1.5 hours, and 75mm is 2 hours; Due to the low thermal conductivity and slow heat transfer of alc sheets, they can resist fires; Alc sheets themselves are inorganic and do not produce harmful gases at high temperatures. Belongs to green and environmentally friendly building materials.
