Hot dip treatment is also known as homogeneous treatment, commonly known as "detonation". Hot dip treatment is to heat the tempered glass to 290°C±10°C, and keep the temperature for a certain time, to promote the rapid crystal phase transformation of nickel sulfide in the tempered glass, so that the originally used after the possible self-detonation of the tempered glass artificially broken in advance in the factory of the hot dip furnace, so as to reduce the use of the tempered glass self-detonation after installation. The method generally uses hot air as the heating medium, known as the "HeatSoak Test", HST for short, literal translation is hot soak treatment.
