The cleaning of quartz tubes in high-temperature tube furnaces is a very important process, because quartz tubes will be contaminated by various chemicals during use, such as metal ions, organic matter, inorganic matter, etc. These contaminants can affect the life of the quartz tube and may even cause the quartz tube to rupture. Therefore, it is very necessary to clean the quartz tube regularly.
Before cleaning the quartz tube, you need to prepare some tools and materials, such as gloves, masks, glasses, brushes, cleaning agents, etc. In addition, it is necessary to ensure safety measures during the cleaning process, such as wearing protective equipment and avoiding direct contact during handling**.
When cleaning quartz tubes, it is necessary to choose the right cleaning agent. In general, acidic or alkaline cleaning agents such as nitric acid, hydrochloric acid, hydrofluoric acid, sodium hydroxide, etc. can be used. However, it should be noted that different cleaning agents have different corrosiveness to quartz tubes, so it is necessary to choose the appropriate cleaning agent according to the actual situation.
First, remove the quartz tube from the high-temperature tube furnace and place it in a well-ventilated area. Then, put on gloves, a mask, and glasses, pour the cleaning agent into the quartz tube and allow it to soak thoroughly. Next, the inner wall of the quartz tube is brushed with a brush to remove contaminants that have adhered to the tube wall. When brushing, pay attention to the moderate strength to avoid scratching the quartz tube.

After cleaning, pour out the cleaning agent in the quartz tube and rinse the quartz tube with clean water until the cleaning agent is completely rinsed. Then, place the quartz tube in a well-ventilated area to dry. It should be noted that the cleaned quartz tube should not be directly exposed to sunlight, so as not to cause the quartz tube to crack due to rapid temperature changes.
After the cleaning is completed, the cleaning effect of the quartz tube needs to be checked. The cleaning effect can be judged by observing whether the inner wall of the quartz tube is smooth and free of residue. If the cleaning effect is not satisfactory, the above cleaning process can be repeated until the satisfactory cleaning effect is achieved.
The cleaning interval of a quartz tube depends on the environment in which it is used and the type of contaminant. In general, it is recommended to wash every six months to a year. If the quartz tube is heavily contaminated during use, it may need to be cleaned in advance.
1) Ensure safety during the cleaning process, wear protective equipment, and avoid direct contact with ** and eyes.
2) The selection of cleaning agent should be carried out according to the actual needs, and the use of cleaning agents with strong corrosiveness to quartz tubes should be avoided.
3) Avoid scratching the quartz tube during the cleaning process, so as not to affect its service life.
4) The cleaned quartz tube should be placed in a well-ventilated place to dry, avoiding direct sunlight.
