Crystallization of glass wine bottles is the precipitation of crystals from the glass body, and the appearance of crystals in glass wine bottles is a common defect in glass wine bottles. Such defects are not allowed to occur in the production of glass wine bottles. So, what causes the crystallization of glass bottles during the production process?
The rate at which glass nuclei form. In the production of glass bottles, the number of new crystal nuclei added in the glass melt per unit time will lead to crystallization of glass wine bottles during the production process. The so-called nucleation growth rate refers to the number of lines of crystal growth per unit time, and the crystal growth rate is usually expressed in microns produced per minute. Therefore, the glass nucleus is one of the important factors affecting the crystallization of glass wine bottles.
Cooling rate control of glass melt. Sometimes in the production of glass wine bottles, if the cooling rate of the glass melt is controlled to gradually reduce the temperature, when the temperature drops to a certain range, the glass wine bottle is prone to crystallization at this time. Generally, this temperature The range usually refers to below the liquidus temperature to above the temperature when the glass becomes a solid, which requires us to pay attention to reasonable temperature control during production to reduce the occurrence of crystallization.
