Glass, the English name of glass, was also called colored glaze in ancient China, and Japanese characters were expressed by nitrate. It is a relatively transparent solid material, which forms a continuous network structure when melting, and its viscosity gradually increases and hardens during cooling, and it will not crystallize. The main component is silicon dioxide.

Classification of glass:

According to chemical composition, it can be divided into soda-lime glass, cesium-potassium glass, aluminum-magnesium glass, lead glass, borosilicate glass, timely glass, aluminum-silicon glass and glass-ceramics.

According to the product thickness, it can be divided into: 2- 15mm glass. Specific:

Electrical and electronic products below 2mm;

2-4mm cars and household appliances;

4-6mm building;

8- 12mm decoration;

/kloc-curtain wall over 0/2mm;

Unit of measurement for glass: heavy box: 10 square meter; 2mm glass is 1 heavy box, weighing 50kg. It is convenient to calculate the total amount between glasses with different thicknesses. 1 ton glass is equivalent to 20 heavy boxes.
