Introduction of the important factors of alumina ceramics when firing

Do you know what is the crucial factor in the firing of alumina ceramics? Obviously, the temperature is an important factor in the firing of alumina ceramics, the following is professional aluminum oxide ceramic Meicheng ceramic manufacturers to elaborate for you in detail.As we all know, alumina ceramics will constantly change at high temperature firing, and different temperatures will be fired into different products, so the temperature must be controlled when firing.

At the same time, the metering control unit, the micro proportion adjusts the spiral of the batching bin to make the batching branch follow. Given the average adjustment signal of the kiln tail temperature, the serial adjustment loop is formed to overcome the macroscopic temperature interference in the kiln. The metering control unit adjusts the feeding amount of the skirt feeder to realize the uniform feeding of aluminum oxide ceramics for heat conduction. The oil supply temperature should be controlled by temperature increase and constant temperature. The electric heater device is set in the oil road into the kiln, and the oil volume is increased through the electric heater, so as to realize the stability of the heavy oil supply temperature.

Because of its unique pore structure and surface properties, hot alumina ceramics is widely used as a loading catalyst carrier in the catalytic field, and a considerable part of the catalytic reactions are carried out in the hydrothermal environment, such as amination, hydration, dehydration, oxychlorination, matrix, catalytic combustion and catalytic oxidation of methane selection reactions.

Under high temperature, high temperature alumina ceramic carrier will occur high temperature sintering and phase change and reduce the carrier ratio surface area, hole structure damage or catalyst inactivation in addition, the existence of water vapor will continue to hydrate with alumina ceramics, alumina particles Al-O-Al bridge bond continuously formed, also aggravate surface sintering caused specific surface area and lead to catalyst inactivation. In the process of low temperature catalytic reaction, high temperature alumina ceramic carrier can occur under hydrothermal conditions, the product pai aluminum below 100℃, 100~110℃ hydration is a mixture of pai and thin alumina, the product above 110℃ is thin water aluminite.

Alumina ceramics fired at high temperature will be constantly changing, different temperatures will be fired into different products, so the temperature must be controlled when firing.

Above is the content of Meicheng ceramics for you.
