Float glass is a glass product widely used in construction, automotive and other fields, and its production process is very important to ensure product quality. This article will delve into the production process of float glass, as well as the detailed steps of each link.
Float glass, also known as flat glass, is a kind of flat and transparent glass made by evenly coating the glass raw material on the surface of liquid tin and passing the float process.
The surface is flat and the finish is high.
Good light transmittance. High production efficiency.
High-purity silica sand and limestone are selected, and high-quality raw materials are obtained through ore refining and mineralization reactions.
Silica sand and limestone are mixed in a certain proportion and sent to a high-temperature melting furnace for melting to form molten glass.
The molten glass is evenly cast on the surface of the liquid tin to form a continuous plate.
By adjusting the process parameters and atmosphere control, the temperature, humidity and other parameters in the float process can be accurately controlled to ensure that the glass surface is smooth and clean.
The glass with liquid tin passes through the cooling zone and is quickly cooled to room temperature, so that it gradually solidifies into a flat plate.
By means of an automatic cutting system, the continuous flat plate is cut into float glass of the right size.
Through infrared thermometers and other equipment, the temperature in the float process is monitored in real time to ensure uniform cooling of the glass.
High-precision instruments such as laser interferometers are used to monitor the thickness of the glass in real time to ensure the consistency of the product.
In the process of studying the float glass production process, we refer to the following professional literature:
Li ming. "Glass Technology".Chemical Industry Press, 2008.
Wang Zhigang. "Glass and Glass Products Manufacturing Technology".China Machine Press, 2015.
The float glass production process is a comprehensive system engineering, which needs to be strictly controlled at every stage to ensure the quality of the final product. With an in-depth understanding of each step, citing specialized literature, and quality control methods, producers are able to better grasp the manufacturing technology of float glass and produce products that are more in line with market demand.
