Glass with its transparent, high visible light transmission, high hardness, wear resistance, light weight and other excellent performance has been widely used in building doors and windows, skylights, curtain walls and other parts, to provide landscape, decoration, daylighting and solar radiation energy for buildings, become the main building indispensable materials; Glass is also an important raw material for the automobile, aircraft, ship and other transportation industries, high-tech industries and many other economic sectors. Some scholars predict that new and better materials will not replace it for a long time to come.

However, glass also has some defects, such as poor thermal insulation, sound insulation, brittleness and low impact strength, which can not meet the requirements of energy-saving, sound insulation, safety and other higher functions of modern buildings, affect its use in various fields. In order to meet the demand, on the basis of keeping the original excellent properties of glass, the secondary technical processing is carried out to change the original defects, endowed with its new heat insulation, thermal insulation, sound insulation, conductivity, anti-electromagnetic wave, anti-infrared, anti-ultraviolet radiation and other excellent performance, improve its impact strength and decorative functions, so that glass in modern industry, construction industry, high-tech fields and various fields of national economy has been more extensive application.

Glass secondary processing technology products are coated glass, insulating glass, laminated glass, toughened glass, thermal bending glass and many other kinds. Processing glass technology in our country from the 20th century 50's began a large-scale research and development, followed by industrial production, almost all kinds of processed glass products are produced in our country, processed glass now our country accounts for about 25% of the total plate glass. From the quantity, variety, quality, production technology and developed countries compared with a large gap (developed countries processing glass accounted for about 70% of the total plate glass) . This situation can not meet the needs of our economic development, which requires us from processing glass production technology research, product variety development, production equipment development, processing glass product application range, in order to promote and promote the development of glass deep-processing technology and the production and application of glass products, we will make greater contributions to the development of new technologies and the national economy.
