The glass or glass products through a physical or chemical method for processing, 5mm tempered glass, glass surface layer permanent stress uniformly distributed, Linyi glass to obtain a processing method of high strength and high thermal stability of the glass and steel called . The glass is heated to a certain temperature, and the glass in accordance with the requirements of rapid cooling rate, so that the glass have a great internal permanent stress, the mechanical properties can be greatly improved silicate glass, this approach is called Glass Physics steel (or hardening). --- Fitted with glass heated manner trachea forced convection heat balance: In general furnace heating element places near thermal equilibrium trachea, endotracheal heated compressed air into hot air, glass manufacturers, glass blowing directly up and down surface. Thermal equilibrium gas on the one hand forced convection heating of the glass, it also makes the heating furnace temperature uniformity. Radiation is everywhere, a cold glass into the furnace, all kinds of heating elements, furnace wall insulation materials, ceramic roller all radiate heat to heat the glass. Linyi glass, glass Yaohui preferred, Yaohui glass door provided by Jinan Glass Co., Ltd. Linyi glass, glass Yaohui preferred, Yaohui Jinan glass door Glass Co., Ltd. (www.jyhhc.com/) this year introduced a new upgrade, the above picture is for reference only, please call the contact picture on this page or telephone obtain the latest information, contact: Liang Jingli.
