Today, new wall building materials have begun to welcome mergers, and many builders are looking forward to them! The technical problems related to the production of aerated concrete equipment have become more and more prominent. For example, the sinking and hardening of billets often confuses many manufacturers and producers. Here, the aerated concrete equipment will explain the solution to the problem of sinking and hardening of the aerated concrete block equipment.
When the slurry gasification operation is completed, the green body enters an intermediate stage, causing the green body to sink and crack. This is due to unfavorable water to material ratio, unacceptable cement and lime quality, and too low slag activity. The aerated concrete block device also has an unhardened appearance of the embryo body. If the hardening time of the green body is too long, it cannot be cut in a short time. It is speculated that too much lime, too little cement, and the complexity of data merging will cause the appearance of the embryo to harden.
To prevent the blank from hardening, we can use appropriate methods. First, we can change the amount of cement; second, improve the cement quality; otherwise, please adjust the ambient temperature. Improve the fixation process. In addition, our requirement is that if lime and plaster are used for grinding, the embryo body will not become hard.
The unevenness of the green body of aerated concrete equipment is due to the different degree of hardening of the green body in the same mold. When the blank is in a static state, because the heat dissipation rate of the blank is too fast, the temperature of some outer surfaces of the mold is high or low, resulting in different degrees of hardening of the blank. According to common sense, we can infer that the closer the mold is, the lower the temperature and the lower the hardness. The uneven hardening of the aerated concrete block equipment is a precursor to a lack of hardened appearance, but it is also considered to be lack of hardening. Therefore, we must pay special attention to this. If the medium hardness of the mold is used as the middle of the cut, cracks may appear. If we cut it with a flip cap, the result will be even worse. Therefore, we must pay special attention to the production process of aerated concrete equipment.
