Description

technical field [0001] This application relates to a physical tempered glass, especially a thin physical tempered glass with good mechanical properties, thermal stability and light transmittance, which can be used for optical glass, automotive glass, architectural glass, decorative glass and aerospace glass, especially in solar panels. Background technique [0002] Tempered glass, also known as strengthened glass, has better mechanical properties and thermal stability than ordinary glass. Generally, the tensile strength of ordinary annealed glass is about 40MPa, while that of tempered glass is about 120 to 200MPa, depending on the thickness of the glass, edge treatment, and whether it is drilled or grooved. Tempered glass is to increase the tensile strength of glass. If the glass is tempered in advance, it can allow a temperature difference of 150 to 200 ° C, and it also increases safety, so it is widely used in various fields. [0003] Tempered glass is a secondary proce...

Problems solved by technology

However, chemically tempered glass is easily damaged due to environmental factors, and the subsequent coating film is not easy, and it is easy to cause film removal, so the service life is short, usually less than 10 years, and the cost is high, resulting in restrictions on use.
