raw materials in the production process of aerated concrete block equipment
October 06, 2021
Aerated concrete block equipment has good processing performance. It can be sawed, planed, nailed, ground and threaded in the manufacturing process. It brings great convenience to construction. When the temperature of aerated concrete block equipment is lower than 600 ° C, the compressive strength will increase slightly.
When the temperature is about 600 ° C, the compressive strength is close to the compressive strength at room temperature. Therefore, the fire resistance of aerated concrete as a building material has reached the fire protection standard. From the vent structure of aerated concrete, it can be seen that due to the internal structure of aerated concrete, a large number of closed gas has a large number of evenly distributed closed holes, so it has sound absorption performance, which is not possessed by materials. Available in general buildings.
The compressive strength of the products produced by the aerated concrete block equipment exceeds 25 kg / cm3, which is equivalent to the compressive strength of 125 clay bricks and lime sand bricks. This is because aerated concrete is light and has good overall performance. The inertia force during earthquake is small and the holes are evenly distributed, which has certain seismic resistance. This will be of great benefit to our earthquake prone country.
Aerated concrete block equipment
According to the basic functions of various raw materials in the production process of aerated concrete block equipment, they can be divided into four categories. Namely: basic constituent materials, gas generating materials, regulating materials and structural materials.
1. The basic constituent materials are silicon and calcium materials; Gas generating materials refer to gas generating agents and bubble stabilizers.
2. Regulating materials include gas generation process regulator and autoclave process regulator; Structural materials include reinforcement and reinforcement preservatives.
In the production process of aerated concrete equipment, other different auxiliary materials can also be used according to the process requirements and the specific conditions of each production equipment.
In the static hardening process of aerated concrete block blank, the hardening effect is different from that of non insulation. If the temperature of the blank disappears rapidly, for example, if there is no heat insulation in northern winter, the blank will not only be greatly affected by the hardening speed, but also shrink and sink seriously. Therefore, at present, all factories tend to use insulation and stop equipment to ensure the solidification speed and uniformity of billets.
Aerated concrete block equipment
The cutting machine used in the aerated concrete block equipment mainly divides and visualizes the aerated concrete body 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 separate and flexible in appearance, can meet the needs of different applications, and can be mechanized through large-scale mechanization. It is also a kind of aerated concrete different from other concrete.
