Packaging Diagram
Storage Conditions: Temperature ≤30℃, humidity ≤65% (no condensation), shelf life is 6 months from the date of delivery.
High Alumino-Silicate Glass(CHIYAN-H1) is adopted Float Glass Process.
Float glass is made by heating raw materials—silica sand, limestone, soda ash, and magnesium in a furnace. When melted, it’s then spread out over a sizable bed of molten tin. As it moves along rollers in the annealing oven during a controlled cooling process, this mixture slowly solidifies over the molten tin. From this point, a single, continuous smooth ribbon of glass emerges as below picture showed:
