Hear soaked and film protection:
''Heat-soaked" is almost the same as the safety film's function which is to enhance the glass integrity. You can either choose heat-soaked to avoid self-explosion or a safety film to protect people who get hurt from the self-explosion.
-More specifically, heat soaking is an extra process before tempering. The glasses use the heat-soaked furnace to expose and almost kill NiS inclusions in the glass, then it will reduce the self-explosion. (hear-soaked furnace picture attached)
-The heat-soaked is for the customer who has strict self-explosion rate control with tempering glass, It usually is used for special customization since this process is more expensive. Most shower glass would like to use a more cost-effective safety film.
Tempered glass undergoes a heat soak process to minimize the risk of spontaneous breakage. During the manufacturing of tempered glass, internal stresses may be present due to nickel sulfide inclusions. These inclusions can cause the glass to break unexpectedly, which poses a safety hazard. Heat soaking subjects the glass to prolonged exposure to elevated temperatures, allowing any potential defects to manifest and be removed from the supply chain. This process ensures that the tempered glass installed in various applications, such as building facades or automotive windows, meets the required safety standards and reduces the likelihood of unexpected breakage.
