Technology of Microwave Drying Equipment for Ceramics
- May 08, 2019 -
Microwave ceramics drying equipment is mainly used in honeycomb ceramics, process ceramics, high-voltage insulating ceramics, special ceramics and so on. Conventional heating, such as flame, hot air, electric heat and steam drying, uses the principle of heat conduction to transfer heat from the outside to the inside of the heated object and gradually increase the central temperature of the object, which is called external heating. It takes a certain amount of time for the central part to reach the required temperature, and longer for objects with poor thermal conductivity. These traditional drying methods have the characteristics of long time, high power consumption, uneven heating, upside-down turning and high labor intensity. Microwave ceramics can be dried. Microwave can penetrate the interior and exterior of an object and heat simultaneously at a frequency of 245 million MHZ. With 2.45 billion shocks per second, molecules rub against each other to generate heat and heat themselves. The advantages of microwave ceramics drying equipment are as follows: (1) The quality of product drying and setting is good and does not crack. 2. Easy to control and flexible to operate. 3. Saving time and high output. 4. Low energy consumption. 5. The production intensity is small and occupies less land. 6. Labor-saving, process-saving, especially easy to connect the front and back processes into automatic lines, reduce the number of handling. 7. Environmental protection, cleanliness and hygiene. No pollution, not to mention the "three wastes" problem. 8. Easy to control and advanced technology. Compared with the conventional method, the equipment is ready to use; there is no thermal inertia, flexible and convenient operation; microwave power can be adjusted, transmission speed can be adjusted. In microwave heating and drying, there is no waste water and no waste gas. It is a safe and harmless high-tech.
