The lightweight foam concrete block making machine has already appeared overseas, and in the original model, the impeller was rotated at high speed to foam, so it is also called "CLC manufacturing facility". Since then, with the advancement of technology, the technical content of lightweight concrete block manufacturing equipment has been continuously improved, new models are constantly appearing, and various technical systems are being formed. According to the foaming principle, only high-speed impeller type, high-pressure air type, and medium-low pressure type are widely used. The only difference between machines of the same type is the difference between the accessory equipment and the automatic control, and the structure of the foam part is almost the same. The principle of lightweight foam concrete block making machine is to introduce outside air into an aqueous solution of a foaming agent. Use advanced methods to completely introduce the outside air into the aqueous solution. It is not possible to generate bubbles from thin air. Since it can introduce air into the foaming agent and spread it evenly, the liquid can come into contact with the gas as much as possible, thereby exciting the foaming agent's surfactant and an electric double layer on its surface. Form the air, thus forming bubbles one after another. Since the main part of foam concrete is foam, the lightweight concrete block manufacturing facility for manufacturing foam has become an important facility in the foam concrete manufacturing process. Without it, you can't make foam concrete. The main features of the lightweight concrete block manufacturing facility are fire protection, light weight, earthquake resistance, sound insulation, convenience of construction, high work efficiency, strong compression strength, harmlessness, environmental protection, energy saving, and long life. Therefore, it is praised by many users for these advantages and its foam manufacturing performance. The lightweight foam concrete block making machine has the following features:
1, the average of the bubbles, the formation of the bubbles should be average, the diameter of the bubbles should be narrow and wide.
Lightweight concrete block manufacturing facilities meet the technical requirements for foam averaging, and the higher the averaging, the better. It is not possible to ensure that the bubble diameters of all bubbles are perfect and equal, but it is also necessary to ensure that most bubble diameters are similar or the same. The narrower the diffusion range, the better. If this is not possible in a lightweight concrete block manufacturing facility, it indicates that foaming performance is not ideal.
2. Foam fineness means that the foam produced is fine and dense.
High-performance lightweight concrete block manufacturing facilities can produce cotton-fine foam. It's easy to make large foams in lightweight concrete block manufacturing facilities, but it takes skill to make fine foams. Therefore, fine foam is also a performance of the excellent performance of lightweight concrete block manufacturing facilities.
3. The foam exudes water, but the foam exudation rate is low and there is no milk foam.
A high foam leaching rate means that a large amount of water is secreted after the foam has completely disappeared. The higher the bleeding rate, the worse the quality of the foam. If your CLC manufacturing facility always produces milk foam with high water, low foam and high bleeding, this type of CLC manufacturing facility does not meet the technical requirements and cannot be selected.
