Quartz tube processing – Items needing attention in heating quartz glass tube

After the quartz glass tube is heated, the following situations occur: the expansion number of the quartz tube is very small, and it will not burst when it is placed in water immediately after heating. Therefore, in the heating tube used in heating equipment, in order to fully radiate the heat emitted by the middle electric heating wire, there is a milky white quartz tube, which can fully radiate the heat emitted by the electric heating wire, so milky white quartz is used. The tube is used as an electric heating tube. Because it is milky white, the heating wire inside is not easy to see. In fact, there is an electric heating wire. Transparent quartz tubes have a characteristic of being able to transmit ultraviolet rays, so good ultraviolet germicidal lamps are made of transparent quartz tubes.

Quartz instrument glass is required to be used at high temperature during the experiment, and it must be wiped clean before use. You can soak it with 10% hydrofluoric acid or lotion, and then wash it with high-purity water or treat it with alcohol. It is not allowed to directly touch the glass of the quartz instrument with the hand when the thread is operated with gloves; the thermal stability of the glass material of the quartz instrument has a high temperature change and can withstand severe stress. But in practice, due to the residual strain and the shape of different products, it has different thermal stability, so it should be paid attention to when using it. Quartz instrument glass is an acidic substance, strictly avoid contact with alkaline substances (such as water glass, asbestos, potassium and sodium compounds) at high temperature, otherwise the anti-crystallization performance will be greatly reduced. Therefore, we must pay attention to various purposes in the process of using quartz instruments, we make materials and corresponding performance characteristics.
