Porcelain crucible manufacturer: How to maintain porcelain crucibles?

With the continuous advancement of science and technology, all walks of life have also developed greatly. The development prospects of porcelain crucibles are also very good, so the demand is constantly increasing, and there are more and more porcelain crucible manufacturers on the market. As a manufacturer, it is also very necessary to tell you about its maintenance methods? Interested partners can come and have a look.

Before using this porcelain crucible, many problems have accompanied everyone, so in order to use it better, you need to understand some of its knowledge points. The main components of porcelain crucible manufacturers are alumina and silicon dioxide. It cannot be used as a flux for alkaline substances. It can be cleaned with acidic reagents. It has heat resistance and can withstand high temperatures up to 1200 degrees Celsius. It is a good container for high-temperature calcination. Solid substance. When using, you can use a washing machine to clean the used porcelain crucible. At this time, the continuous upgrading of cleaning equipment technology and the countless types of cleaning equipment can also come along with it. Although cleaning kits are easy to use and operate, they have two disadvantages that cannot be ignored. Porcelain crucible manufacturers recommend placing the porcelain crucible to be cleaned in a high-temperature tube furnace and calcining it in an air atmosphere. Since carbon-loaded metal oxides were prepared by high-temperature calcination in the early stage, you will find that this method can only remove carbon, while metal oxides still remain in the porcelain crucible and cannot be removed. In addition, the air calcination method has the disadvantages of high calcination temperature, long time, and high energy consumption. Porcelain crucible manufacturers believe that the common hydrothermal method is carried out in a specially designed sealed reaction vessel, using an aqueous solution as the reaction medium, heating the reaction vessel to create a high-temperature and high-pressure reaction environment, so that substances that are insoluble or difficult to dissolve at room temperature can be dissolved under conditions.

Porcelain crucible manufacturers say that to avoid unnecessary damage during use, first, handle with care during transportation to prevent breakage. Porcelain crucible manufacturers recommend that you store it in a dry and ventilated place or on a wooden frame to avoid affecting the crucible performance due to high environmental humidity. Before use, the crucible temperature should be gradually raised to 500℃ by baking or other methods. Or when adding materials, the amount of materials should be added according to the capacity of the crucible. Do not add too much, otherwise it is easy to cause the crucible to expand, affecting subsequent use. In addition, during operation, the molten material should generally not be filled too full to prevent the heated material from jumping out, allowing air to freely enter and exit to ensure the normal progress of the reaction, but at the same time, when refining the metal liquid, reduce the excessive contact between the metal liquid and the air to prevent the metal liquid from reacting with the air. Secondly, it is recommended that you choose suitable tools and crucible fixtures according to the shape. Porcelain crucible manufacturers indicate that when clamping, the center of the crucible should be clamped to avoid damage caused by local hand force. Now its raw materials can be summarized into three categories. One is natural crystalline graphite, the second is plastic refractory clay, and the third is hard-fired skeleton mature material similar to kaolin.

The above article content is an introduction to the maintenance methods of porcelain crucibles by the editor. If you didn't understand it before, you can take a look now. In the next issue, the porcelain crucible manufacturer will also tell you about the knowledge points related to it. Remember to watch it.
