two. working principle    
The desktop ultraviolet ozone light cleaning machine GXT18A-01 produced by Beijing Aerospace Hongda Photoelectric Technology Co., Ltd. uses the photosensitive oxidation of organic substances by ultraviolet photons to clean the organic compounds (hydrocarbons) adhering to the surface of the object. Purpose. Most organic compounds have a strong ability to absorb ultraviolet light with a wavelength of 254 nm. After absorbing the ultraviolet light, they are decomposed into ions, free atoms, and excited molecules. and neutral molecules, which is photosensitization. Oxygen in the atmosphere generates ozone O 3 and atomic oxygen O after absorbing ultraviolet photons with a wavelength of 185 nm. The generated O 3 has a strong absorption effect on ultraviolet light with a wavelength of 254 nm. Under the action of photons, ozone will again It is decomposed into oxygen and excited oxygen atoms O * . Because the excited oxygen atoms O * are extremely active, the photosensitive decomposition products of carbon and hydrogen compounds on the surface of the object are combined into volatile gases under its oxidation: carbon dioxide, nitrogen and water vapor, etc., escape from the surface of the object, so as to achieve the purpose of completely removing the stubborn organic substances adhering to the surface of the object

Four. Features
 
1. Compact structure, small volume, large cleaning area (180*180);
 2.Equipped with an air cooling circulation system, which successfully solves the common heat dissipation problem in the washing machine;
 3.High power, the maximum power is 180W;  
4. A reflector is used to reflect the UV light emitted by the UV lamp to the material to be cleaned, thereby enhancing the intensity of the material to be cleaned and improving the cleaning efficiency;  
5.The distance between the material and the light source can be adjusted to maintain a small appropriate distance between the material and the UV lamp. Usually, the gap must be less than 10mm to achieve the best cleaning results (ie light intensity and appropriate ozone concentration, maintaining a suitable space to ensure that Proper ventilation, control the furnace temperature);
6.   Adopt electronic control circuit, digital display, simple and convenient operation.      
Relevant experiments have proved that after chemical and physical cleaning, the contact angle of the glass surface (the main parameter to measure the cleanliness of the surface of the object is to use quantitative pure water droplets to the surface of the object, and the angle formed by the water droplets) can only be around 50 degrees. It is far from enough for STN products, and after UV cleaning, the contact angle can be reduced to below 20 degrees, which can meet the technological requirements of STN products.
