The thermal expansion coefficient of the quartz glass rod is very small, and it can withstand severe temperature changes. When the quartz glass rod is heated to about 1100 ℃, it will not crack when put into normal temperature water.
What are the advantages of quartz glass rod?
Advantages 1. High temperature resistance: the softening point temperature of the quartz glass rod is about 1730 ℃, which can be used for a long time at 1100 ℃, and the use temperature can reach 1450 ℃ in a short time.
Advantages 2. Good edge performance: the resistance of quartz glass rod is 10000 times that of ordinary PE pipe, which is an excellent electrical insulating material and has good insulation performance even at high temperature.
Advantages 3. Good thermal stability: the thermal expansion coefficient of quartz glass rod is very small, and it can withstand severe temperature changes. The quartz glass rod will not crack when heated to about 1100 ℃ and put into normal temperature water.
Advantages 4. Good light transmittance: quartz glass rod has good light transmittance in the whole spectrum band from ultraviolet to infrared, and the visible light transmittance is more than 93%, especially in the ultraviolet spectrum region, the Z large transmittance can reach more than 80.
Advantages 5. Strong corrosion resistance: Except hydrofluoric acid, quartz glass rod hardly reacts with other acid substances. Its acid resistance is 30 times that of ceramic and 150 times that of stainless steel. Especially, its chemical stability at high temperature is incomparable with any other engineering material.
