Product usage precautions
1. When using quartz window panels, they should be handled with care and cleaned before use. Generally, ethanol mixture or anhydrous ethanol should be used for cleaning. Gloves should be worn during operation, and direct contact with the window panels, especially those that have already been coated, is not allowed.2. Each specification of quartz window panel has a high operating temperature, which should not be exceeded during use
3. If the quartz window piece is already working at high temperatures, it is recommended to use it continuously, which is beneficial for the service life of the window piece. Frequent exposure to high and low temperature cycling environments may shorten the service life of the window piece.
4. Quartz window panels have good thermal stability and can withstand rapid temperature changes, but their thermal stability may decrease due to the influence of stress and mechanical dimensions.
5. Quartz window panels have acid and alkali resistance properties, but when using them, it is necessary to avoid mixing multiple chemical acid and alkali substances in contact with the quartz window panels.
