Tempered Glass
Tempered or toughened glass is a type of safety glass processed by controlled thermal to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass (a.k.a. annealed glass) does. The granular chunks are less likely to cause injury.
Tempered glass is often used in applications where using standard glass could pose a potential danger. Tempered glass is stronger than standard glass and does not shatter into large shards when broken. This is important, because it can greatly minimize potential danger in the case of a break. Manufactured through a process of extreme heating and rapid cooling, tempered glass is much harder than normal glass.
In the case that tempered glass does break, it shatters into small pebbles that are void of dangerous, sharp edges. As tempered glass is considered to be much safer than normal glass, you may often here it referred to as safety glass or TOUGHENED GLASS . Tempered glass has a wide variety of uses that you'll find just about everywhere. In fact, the shower doors in your bathroom or the side glass on a motor vehicle are examples of tempered glass.
Annealed glass can be processed into Clear Tempered Glass, Ultra Clear Tempered Glass, printed tempered glass, back painted tempered glass, tempered Laminated Glass, tempered Insulated Glass , tempered Vacuum Insulated Glass and so on, custom made on project request. Can be used for windows, doors, partitions, handrails, balcony, balustrade, fence, table top, decoration, kitchen splashbacks and so on.

“Since the use of coal mine cooling and cooling system, the fully mechanized mining face is much cooler!†This is the reporter’s 762-meter fully mechanized mining face in the Liuzhuang mine of Guotou Xinji Company. I heard the miners’ first domestic coal mine cooling and cooling system. Evaluation of operational effects.
Liuzhuang Mine is China's first digital deep mine with an annual output of 8 million tons. At the same time as the pilot production in October last year, SDIC Xinji Company equipped Liuzhuang Mine with an internationally advanced coal mine refrigeration and cooling system to form a capable force to inspect the cooling and cooling of several deep mines in Germany, Denmark, Sweden and South Africa. system. Carry out scientific research and independently design the cooling and cooling technology system of Liuzhuang Mine. With an investment of 7.5 million US dollars, the company has introduced coal mine refrigeration and cooling equipment from Germany's Simag, Botec and Siemens. At the beginning of this year, the installation of ground refrigeration units, pressure exchange systems and automatic control systems was in full swing. During the construction, SDIC New Collection Company installed more than 7,000 meters of refrigeration pipelines and 11 air coolers. Using the coal mine cooling and cooling system, the air temperature of the mining face of Liuzhuang Mine will not exceed 26 °C, thus meeting the requirements of the Coal Mine Safety Regulations.
