Background
Quartz glass is an amorphous material with a single component of silica, and its microstructure is a simple network composed of silica tetrahedral structural units. Since Si — O chemical bond energy is large and the structure is compact, the silica glass has unique properties, and particularly, the optical properties of the transparent silica glass are excellent and have excellent transmittance in a continuous wavelength range from ultraviolet to infrared radiation. The formation of quartz glass is a result of its high melt viscosity at high temperatures. The method is used for manufacturing semiconductors, electric light sources, semiconductor communication devices, lasers, optical instruments, laboratory instruments, electrical equipment, medical equipment, high-temperature-resistant and corrosion-resistant chemical instruments, chemical industry, electronics, metallurgy, building materials, national defense and other industries, and is very wide in application.
Quartz glass is often used as a base material of the heating element, including a heating element using a heating wire, a xenon lamp, or the like as the heating element in a quartz tube. However, such heating bodies are used in the field of industrial heating, and have the disadvantages of light radiation attenuation, low heat radiation efficiency and the like; in order to overcome the problem, the method provided by the prior art is to coat the heating slurry on the quartz glass substrate, which avoids the low radiation efficiency of the heating coating on the air convection radiation, but because the interface bonding force between the glass substrate and the heating coating is weak and the adsorptivity is not high, the coating is easy to fall off in the working process, especially under the condition of rapid temperature rise and rapid temperature decrease.
