There is no fixed standard for the service life of quartz cotton, usually between 1-5 years, and the specific duration depends entirely on the usage environment, working conditions, and maintenance.
Core factors affecting the service life of quartz cotton
Temperature: This is the most critical factor. The long-term use temperature of quartz cotton is generally between 1000-1200 ℃, and it can withstand 1400 ℃ in the short term. If it exceeds the rated temperature for a long time, it will accelerate its fibrosis, shrinkage, and even pulverization, greatly shortening its lifespan; If the temperature is always controlled within a safe range, the lifespan can be extended to more than 5 years.
Corrosive environment: If exposed to strong acids, strong bases, or corrosive gases/liquids containing fluorine, chlorine, etc., the fiber structure of quartz wool will be damaged, leading to performance failure. In a non corrosive dry environment, its lifespan will be significantly longer.
Mechanical damage and dust pollution: Quartz cotton has a brittle texture, and frequent vibration, collision, or airflow can cause fiber shedding; If there is too much dust in the environment, it will block its pores, affect the insulation/filtration effect, and indirectly cause it to be scrapped in advance.
Maintenance frequency: Regular inspection and cleaning of surface dust to avoid mechanical friction can reduce unnecessary wear and tear; If not maintained for a long time, minor damage will gradually accumulate and shorten the overall service life.
