REXI Tempered Glass is made by heating flat glass to just below its softening temperature (650℃) and suddenly chilling it with jets of cold air. It results in the outer skins under powerful compressive stress and the interior with severe tensile stress. In consequence, the impact applied to the glass will be overcome by the compressive stress on the surfaces to assure safety of use.
It is the perfect option for architects who must meeting building codes and toughened and strengthened for safety requirements. Guaranteeing quality, the material used in the production’s quality should be determined by both China tempered glass supplier and costumer. It is available in all of our standard float thicknesses and sizes, thus the tempered glass price is decided by the different thickness.
Tempered glass is a kind of prestressed glass. Through physical or chemical methods, uniform compressive stress is formed on the surface of the glass, and tensile stress is formed inside. It is the presence of such steel stress that can effectively organize the microcrack propagation on the glass surface, so that the tempered glass has high mechanical strength, good thermal stability and safety performance.
（1） Bending Strength
Tempered glass cut to size has excellent bending strength, which is 4-5 times that of ordinary float glass. The bending strength of tempered glass with thickness of 5mm can reach up to 152MPa.
The deflection of tempered glass is also 3-4 times larger than that of ordinary glass. A tempered glass of 1200*350*6mm can have a maximum curvature of 100mm. Tempered glass also has good water pressure resistance.
The thermal stability of tempered glass refers to the properties of the glass subjected to severe temperature changes without being destroyed. Toughened glass can withstand temperature changes up to 260-330 ° C, while ordinary glass is only 75-110 ° C.
For example, tempered glass (510*310*6mm) is placed in a 0°C environment, and then molten lead water (327.5°C) is poured. The sample still does not break.
Tempered glass also has good safety performance, because when the tempered glass is broken, the whole glass has a honeycomb-shaped obtuse angle small particle (also known as "glass rain"). The particles have no sharp corners and have very good safety. The reason is that there is tensile stress in the inner layer of the tempering. When the force is broken, under the pressure protection of the outer layer, the glass becomes a collection of cracks, but it is not easy to be scattered, and the fragments are honeycomb-shaped obtuse-angle small particles.
The impact strength of tempered glass is 4-5 times greater than that of ordinary glass.
Glass is brittle material; in the event of accidents it may bring an immeasurable consequence. The equipment manufacturer is bound to put the product safety on the most important position. To improve the strength of the glass, the main method is tempered glass. People tempered the glass by the physical and chemical way. For the ultra-thin glass and high flatness requirement are, chemical tempering is a better choice.
Glass has been widely used as an optical material for its high transparency. In recent years, with the continuous advancement of glass technology and the continuous development of glass properties, the application field of glass has been expanding. As a kind of heat-resistant and impact-resistant glass and high softening temperature, toughened glass is an ideal window material for high temperature and high pressure pipes, vessels, liquid level gauges and instruments.
China REXI tempered glass can avoid potential cuts and injuries as a result of broken glass. It is widely used in all doors (sliding, swing, etc.), windows，shower enclosures, partitions and elevator enclosures, curtain walls and storefronts, automotive windows shields, also widely used in chemical, scientific experiments and other fields.
