Advantages Of Quartz Casing For Ultraviolet Sterilizer Accessories

2019-11-08

Quartz casing is one of the accessories of ultraviolet sterilizer, which is made of natural crystal quartz (crystal or pure silica), or synthetic Silane, which is made of high temperature melting and contains only one component of silica. Let's take a look at its advantages:

1. High temperature resistance

The softening point temperature of quartz tube is about 1730 ℃, which can be used for a long time at 1100 ℃ and 1450 ℃ for a short time.

 

2. Corrosion resistance

Except hydrofluoric acid, quartz tube hardly reacts with other acids, and its acid resistance is 30 times of that of ceramics and 150 times of stainless steel, especially the chemical stability at high temperature, which is incomparable to any other engineering material.

 

3.good thermal stability

The thermal expansion coefficient of quartz tube is very small and can withstand severe temperature change. When the quartz tube is heated to about 1100 ℃, it will not burst in normal temperature water.

 

4. good transmittance

Quartz tubes have good transmittance in the whole spectral band from ultraviolet to infrared, and the transmittance of visible light is above 93%, especially in the UV spectrum, the transmittance can reach more than 90.

 

5. good electrical insulation

The resistance of quartz tube is 10,000 times of that of ordinary glass. It is an excellent electrical insulation material and has good electrical energy even at high temperature.

 

Quartz casing can prevent water and air flow, prevent damage, leakage, temperature fluctuation and environmental change, protect ultraviolet lamp tube, but also ensure the efficiency of ultraviolet sterilizer.
