The spiral quartz heating tube is a heating element with a resistance wire installed in a quartz glass tube and a spiral structure:
1. Structure and materials:
– Quartz glass tube: Quartz glass is the main shell material of the spiral quartz heating tube, with the advantages of high purity, high temperature resistance, corrosion resistance, good thermal stability and light transmittance. Its silicon dioxide content is usually very high, for example, it can reach about 99.9%, which enables it to work stably in high temperature environments.
– Resistance wire: Located inside the quartz glass tube, it is generally made of metal materials such as nickel-chromium alloy. This resistance wire has a high resistivity and can efficiently convert electrical energy into thermal energy after power is turned on, generating heat to make the quartz tube heat up.
