3 major factors that cause damage to alumina ceramic parts
1. External force: A major factor in the wear of alumina ceramics partsis the strong external force. Generally, it is caused by impact force and pressure during operation. It is worn or broken due to strong external forces. This is unfavorable for alumina ceramics. We should try our best to avoid collisions with objects during operation to minimize the damage.
2. The influence of the external environment: The general environmental factors include the influence of the medium in the environment, the influence of wind, the influence of temperature, etc. Sometimes the alumina ceramic parts are worn out due to long-term wind erosion. Sometimes it is caused by the slight melting of alumina ceramics caused by high temperature, causing damage. It may also be due to the impact of impurities in the environment. No matter what factors in the environment cause the wear of alumina ceramics, we must carry out maintenance and replacement parts in time to ensure normal operation.
All products through the German DIN standards: DIN43724 / DIN43725 / DIN40680
3. Excessive use time: Another reason for the wear of alumina ceramics parts is the wear after long-term use. This is caused by the time factor. Generally, we think it is a normal factor, but it needs to be replaced with a new one after excessive wear and tear.
