Alumina Ceramics:
The production process of grouting is composed of the above 9 processes, among which: eating pulp is the process of the mold adsorbing the moisture in the mud to form a green body. Putting slurry, also known as empty slurry, is to discharge excess mud when the green body has a certain thickness. The returned slurry is returned to the slurry tank (or tank). The methods of slurry return are: (1) artificial end barrel slurry: (2) natural pressure slurry, using the slope of the pipeline to return the slurry to the slurry tank; 3) Use the mud pump to pump back the remaining slurry: (4) Negative pressure back to the slurry, that is, the negative pressure formed by the vacuum pump is used to pump the mud back to the mud tank. Except for the first type, they all belong to pipeline backfilling. Consolidation: The green body is very soft after being put out, and it can not be immediately demolded. It takes a period of time to continue to drain the green body and increase its strength. This period of time is called consolidation. One of the main processes of pulp forming, its duration is about half of the pulping time. During the consolidation process, because the model continues to absorb water, the water content of the green body continues to decrease, and the green body gradually shrinks due to the drainage of water. When the water content of the green body When it drops to about 19-20% (that is, the demolding point), the consolidation process ends, and the green body is easily removed from the model at this time. Take the mountain. Demolding: The process of removing the rough billet from the model. Mastering the demolding point is a key. Premature demolding is not enough, the strength of the billet is not enough, demolding is difficult, and the blank is easy to collapse after demolding. Late, the green body will crack. Stick repair: including one-time repair, punching and bonding. The traditional grouting method, the inner and outer surfaces of the blank after the demoulding are rough. Generally, multiple repairs are required, and the sticky The workload is also very large.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
