The production process of alumina industrial ceramics
Alumina industrial ceramic material is not uncommon. This type of industrial ceramic material applies the chemical properties of aluminum oxide, but does not combine aluminum oxide with ceramics. Compared with other materials with the same path, this type of aluminum oxide ceramic material has significant advantages in thermal conductivity and ductility.
Alumina, also known as chemical aluminum oxide (Al2O3), is the scientific name, while the chemical composition of ceramics is usually silicon dioxide (SiO2) and calcium carbonate (CaCO3). The precision processing technology of aluminum oxide ceramics is powder preparation, which has high molding rate, fast work efficiency, and high product success rate.
The precision processing technology of alumina industrial ceramics is to first prepare the incoming aluminum oxide powder into powder materials according to different product requirements through different molding processes. The particle size requirement for this powder is 1 μ If the manufactured product is high-purity alumina industrial ceramic parts or industrial ceramic structural components below, in addition to the purity of aluminum oxide at 99%, it is also necessary to finely grind the powder and make the particle size distribution of the already ultrafine crushed powder uniform. Then, the ultrafine crushed powder is formed by extrusion or injection molding. During the preparation process, binders and plasticizers need to be introduced into the powder. It should be noted that there is a certain proportion requirement between binders and plasticizers.
Cleaning method for alumina ceramic tubes
Method 1: Clean with clean water
The surface of alumina ceramic tubes is smooth and will not hide many other substances during use. It can be gently cleaned with clean water.
Method 2: Use tools to rinse
For a alumina ceramic tube, because it is very wear-resistant, it can also be cleaned with some high friction coefficient cleaning tools.
Method 3: Ceramic detergent or soap
If alumina ceramic tube is very dirty, you can buy ceramic detergent or soap at this time. As long as you use the cleaning agent and water together, you can quickly wash away those dirty things.
