El hormigón aireado autoclavado o AAC es un material de construcción sostenible con excelentes propiedades de aislamiento e insonorización. Los bloques AAC son livianos, fácil de cortar e instalar y se puede fabricar con materiales reciclados como cenizas volantes y escoria. An Máquina para fabricar bloques AAC and production line can help produce high quality AAC blocks on an industrial scale.
AAC blocks are commonly used as wall panels in both commercial and residential construction projects
Compared to traditional brick and block walls, AAC walls offer many benefits:
•Insulation – AAC has a higher insulation value compared to concrete blocks, making buildings cooler in summer and warmer in winter. This reduces energy costs for heating and cooling.
•Strength – AAC blocks have compressive strengths comparable to concrete blocks but are around 50% lighter in weight.
•Durability – AAC can withstand harsh weather conditions and resists mold, moisture and termites. It has a service life of over 50 años.
•Recyclability – Up to 80% of the raw materials used in AAC production are recycled waste like fly ash and slag. This makes it an eco-friendly building material.
•Sound insulation – The cellular structure of AAC provides excellent sound absorption, reducing noise transmission between rooms by up to 50%.
An AAC block making machine is used to manufacture AAC blocks in a continuous process
The key components of an AAC production line include:
1.Mezclador – Dry ingredients like cement, cal, additives, fillers and sand are mixed uniformly using a screw or drum batch mixer.
2.Foaming agent dosing system – A precise amount of foaming agent like aluminum powder is added to produce the required volume of foam.
3.Molding machine- The wet AAC mix is fed into bottom open molds with dies of different block sizes.
4.Vibrador – The filled molds are vibrated to release air bubbles and ensure uniform foam distribution within the blocks.
5.Curing chamber – The molded AAC blocks are cured in a curing chamber at temperatures between 160 a 200 °C for 16 a 24 horas . This triggers a reaction that hardens the blocks.
6.Cooling tunnel – The cured AAC blocks pass through a cooling tunnel to slowly bring them down to room temperature before demolding.
7.Demolding system – The hardened AAC blocks are removed from the molds and packed for storage and transport.
Some key factors to consider when choosing an AAC block making machine include:
•Production capacity – The machine should have sufficient capacity to meet your required output of AAC blocks per hour. Larger machines with multiple molds can produce up to 50,000 bloques por día.
•Mold dimensions – Choose molds compatible with standard AAC block sizes in your country – 400x200x200 mm, 500x250x200 mm, etc..
•Reliability – Opt for a machine made with durable components and a simple design that is easy to operate and maintain.
•Flexibility – Consider machines that allow production of hollow as well as solid AAC blocks using the same molds and dies.
•Raw material compatibility- Ensure the machine can efficiently produce AAC blocks using the raw materials available in your region.
