Features of clear tempered glass for greenhouse and building

Clear tempered glass belongs to safety glass. Toughened glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical, or physical methods are usually used to form compressive stress on the surface of the glass. When the glass bears external force, it first counteracts the surface stress, thus improving the bearing capacity, enhancing the glass’s own wind compression, heat and cold resistance, impact, and so on.

Clear tempered glass for greenhouse and building is made by cutting ordinary annealed glass into the required size, then heating it to about 700 degrees near the softening point, and then cooling it rapidly and evenly (usually 5-6MM glass is heated for 240 seconds at 700 degrees and cooled for about 150 seconds). 8-10MM glass is heated at 700 degrees for about 500 seconds and cooled for about 300 seconds. In short, according to the thickness of glass, the choice of heating and cooling time is also different.

Clear tempered glass for greenhouse and building shower wall panels is a type of glass with even compressive stress on the surface which is made by heating float glass to a nearly softening point and then cooling it down rapidly by air. During the instant cooling process, the exterior of glass is solidified due to rapid cooling while the interior of the glass is cooled down relatively slowly. This process will bring the glass surface compressive stress and the interior tensile stress which can improve the mechanical strength of glass by germination and result in good thermal stability.

Features of clear tempered glass for greenhouse and building
1. 5 times harder than ordinary float glass, stronger resistance to thermal breakage than annealed or heat strengthened glass.
2. Clear tempered glass for greenhouse and building once breakage occurs, the glass disintegrates into small cubical fragments, which are relatively harmless to the human body.
3. It withstands an abrupt temperature change of 220 Centigrade.
4. Sizes are produced as per customer request.

Please notes of clear tempered glass for greenhouse and building
Clear tempered glass for greenhouse and building specification should be confirmed before putting the sheet glass into the toughening furnace, the tempered glass can’t be cut anymore after out of the toughening furnace, otherwise, it will be broken.
