The upgrading of residents' consumption structure, encouraging independent innovation, new rural construction and urbanization will ensure that the domestic market's medium- and long-term demand growth trend for glass products remains unchanged. With the development of industries such as construction, automobile, decoration, furniture, information industry technology and people's requirements for living space environment, functional processing products such as safety glass and energy-saving insulating glass have been widely used. The supply and demand pattern and consumption structure of flat glass are changing.
The development of the glass industry is linked to many industries in the national economy, and the glass industry plays a positive role in promoting the development of the entire national economy. Therefore, the "Eleventh Five-Year Plan" also put forward specific requirements for the development of the glass industry. Various laws and regulations have also been promulgated to regulate the healthy development of the glass industry. Under the new situation, the glass industry must change the growth mode according to the requirements of the scientific development concept and effectively adjust the industrial structure to promote the healthy development of the industry.
Characteristics of tempered glass: Tempered glass is designed to heat the high-quality float glass near the softening point, and rapidly cool the glass surface to distribute the compressive stress on the glass surface, while the tensile stress is in the center layer. Because of the strong equal compressive stress, The tensile stress generated by the external pressure is offset by the strong compressive stress of the glass, thereby increasing the safety of the glass.
1. Increased strength: After tempering, the mechanical strength, impact resistance and flexural strength of the glass can reach 4-5 times that of ordinary glass.
2, the thermal stability is improved: tempered glass can withstand a large temperature difference without damage, and the resistance to variable temperature difference is three times that of ordinary float glass of the same thickness.
3. Improved safety: After the tempered glass is damaged, it will quickly show tiny obtuse-angle particles, thus maximizing personal safety. Applications: Furniture, electronics and electrical industry, construction, decoration industry, bath rooms, automobiles, escalators, and other places where safety and temperature differences are particularly needed, and can be used as the original film of insulating glass and laminated glass.
