REXI bent glass is different from ordinary flat plate shape, it is a special type tempered product with obvious curved body curvature.
In Chinese factory, there are many strict standard index to control its quality to make sure the price on the market not be affected.
The curvature of the flat part should not exceed 0.3% when arched, and should not exceed 0.2% when the waveformed. The Impact resistance must be tested by China bent glass manufacturers under following steps: Take 6 pieces of bent tempered glass for testing, and the number of sample destruction is not more than 1 piece, the patch can be regarded as qualified, and more than or equal to 3 pieces is unqualified. When the number of damages is two, another six pieces are to be tested, and all the samples must not be destroyed.
Thermal shock resistance test is performed by China bent glass suppliers as follows: The 300mmX300mm sample was placed in an oven at 200°C士2°C, and kept hot for more than 4 hours. Immediately after removal, the sample was immersed in a 0°C ice-water mixture. The height of the sample soaked in the mixture should be more than 1/3 of the total height, then observe whether the sample is damaged after 5 minutes. The scale-like peeling of the glass surface and edges should not be considered as damage.
