Glass, tempered glass surface after the heat treatment process should be defined by the pressure layer, the mechanical strength and thermal shock strength is improved 8mm glass, and has a special status debris. Tempered glass Features Security: When the glass is broken force debris into a honeycomb-like particles Suixiao obtuse angle to reduce damage to human body. High strength: the impact strength of glass of the same thickness is 3-5 times that of ordinary glass bending strength is 3-5 times that of ordinary glass. Thermal stability: Tempered glass has good thermal stability, can withstand the temperature difference is 3 times that of ordinary glass, can withstand 200 ℃ of temperature changes. Non-cutting nature: steel rear glass can not cut, drill or change shape. Ordinary annealed glass, tempered glass is first cut into the required size, then heated to its softening point of 700 degrees, then rapidly cooled to obtain uniform (usually 5-6MM glass is heated at about 240 seconds 700-degree heat, cool for about 150 seconds .8-10MM glass is heated at about 500 seconds 700-degree heat, cool for about 300 seconds. In short, according to different glass thickness tempered glass window, select the heating cooling time is different). After treatment of steel glass surface to form a uniform compressive stress, and the internal tensile stress is formed 12mm tempered glass, so the glass bending and impact strength can be improved, and its strength is about four times more than ordinary annealed glass. Have a good glass steel processing, can no longer be any cutting, grinding and other processing or by damaged, otherwise it will cause damage even stress balance and "destroyed." Glass lowe, Yaohui glass quality first (online consultation), Dongying glass by Glass Co., Ltd. Jinan Yaohui. Jinan Yaohui Glass Co., Ltd. (www.jyhhc.com/) Shandong Jinan, architectural glass leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Yaohui glass in Jinan leadership with the staff warmly welcome all inquiries negotiations to create the Jinan Yaohui glass better future.
