Autoclaved aerated concrete blocks The equipment has good processing function. Capable of sawing, planing, nailing, grinding, and thread processing in the production process. It brings great convenience and sensitivity to construction. When Aerated concrete block When the temperature of the equipment is lower than 600 ° C, the compressive strength will be slightly increased.
When the temperature is about 600 ° C, the compressive strength is close to the compressive strength at room temperature, so the fire prevention function of aerated concrete as construction materials meets the fire prevention specifications. From the ventilation hole structure of aerated concrete, it can be seen that due to the internal structure of aerated concrete, many closed gases have many evenly distributed closed holes, so they have sound absorption function, which is not available for general construction.
The compressive strength of products produced by aerated concrete block equipment exceeds 25 kg/cm2, which is equivalent to the compressive strength of 125 clay bricks and lime sand bricks. This is because the aerated concrete is light in weight and has good overall function. The inertia force during the earthquake is small, the holes are evenly distributed, and it has certain seismic resistance. This will be of great benefit to our earthquake prone countries.
According to the basic functions of various raw materials in the production process of aerated concrete blocks, they can be divided into four categories. That is, basic composition data, gas production data, dispatching data and structural data. 1. Basic composition data are siliceous and calcareous materials; Gas production data refer to gas production agent and bubble stabilizer. Conditioning data includes gas generation process conditioner and autoclave process conditioner; The structural data includes reinforcement and reinforcement preservative.
In the production process of aerated concrete equipment, other different auxiliary data can also be used according to the process requirements and specific conditions of each production equipment.
In the process of static hardening of aerated concrete block blanks, the hardening effect is different from that of non insulation. If the temperature of the billet disappears rapidly, for example, if there is no heat insulation in the northern winter, the billet will not only be greatly affected by the hardening speed, but also shrink and sink seriously. Therefore, at present, all factories tend to use heat insulation and stop equipment to ensure the solidification speed and uniformity of the billet.
The cutting machine used in the aerated concrete equipment mainly cuts and visualizes the main body of aerated concrete to meet the shape requirements of aerated concrete products. The cutting process reflects the aerated concrete, which is easy to form, large in size, easy to leave, sensitive in appearance, able to meet the needs of different uses, and can be mechanized through large-scale mechanization. It is also a kind of aerated concrete different from other concrete. Highlight advantages.
