The invention discloses a tempered glass processing technology. The processing technology mainly comprises the following steps of glass surface cleaning, glass preheating, silicon dioxide powder spraying on the glass surface, high power heating on glass, cooling liquid spraying for cooling and natural cooling. According to the tempered glass processing technology, the production technology is simple, the made tempered glass has high surface stress and toughness, and the yield is increased; meanwhile, cooling is conducted by adopting a cooling liquid, the cooling speed can be increased, and the tempered glass cannot burst.
