From choosing the right glass material types and proportions to scientifically assimilating them all to produce the glass we know well, here, we use a step-by-step process to answer how glass is produced. 1. Smelting and refining In order to make transparent glass, the correct raw materials are needed. This includes silica sand (SiO2), sodium oxide (Na2O) for soda ash, calcium oxide (CaO) for limestone/dolomite, dolomite (MgO) and feldspar (Al2O3). These ingredients are mixed in an appropriate ratio, and then the entire batch of products is flew into a furnace heated to 1500 degrees Celsius. In order to impart color to the glass, certain metal oxides are also mixed in this batch of glass. 2. The molten material flowing out of the floating bath from the furnace flows into the floating tank, which is composed of a mirror made of molten tin. This material enters the bath at a temperature of 1500 degrees Celsius and leaves the bath at a temperature of around 650 degrees Celsius. Its shape at the exit is like a solid ribbon. 3. Reflective glass coating. After that, if you want to produce a reflective glass surface that helps cool the room, you must follow the coating procedure and coat the surface of the cooled ribbon at a high temperature with a hard coating or a soft coating. 4. Annealing Next, in order to eliminate the internal stress accumulated in the glass, a process called annealing is carried out. This process allows the glass ribbon to pass through one layer, eliminate any stress on the glass surface, and gradually cool it to a hardened form. This makes it easier to cut and shape the glass. 5. Inspection Through keen and advanced inspection technology, more than 100 million inspections can be performed in the entire glass manufacturing process to identify bubbles, stress, or refuse to melt sand. This is essential to ensure the quality of the glass form. 6. Cut diamond steel according to the order to trim and cut the glass ribbon into a square shape. For a variety of door and window requirements, the required glass aluminium processing machine is also different. The insulating glass equipment provided by the machine is currently a very popular one. This kind of glass aluminium processing machine can produce insulating glass with thermal insulation performance. 126
