toughened glass is made by powerful treament,and have greatmechanical property and heat resistant and quake-proof.
toughened glass,the strong and safety glass,is widely used inconstruction.Its performance of anti-impact,anti-bending andanti-tmepeerature difference is 3 to 5 times than the ordinaryglass,it becomes small round pieces when broken.Thus people willnot get hurt. This type of glass is intended for glassfacades,sliding doors,building entrances,bath and shower enclosuresand other uses requiring superior strength and safetyproperties.
All fully tempered glass for a project can be heat-soaked in ouroven. The concept of heat-soaking is defined as the transfer ofpotential on-site breakage of tempered glass to breakage in thefactory under a controlled process of accelerating the inversion ofnickel sulphide stones to their low temperature phase.
While heat-soaking does not guarantee that breakage will becompletely eliminated in the installed tempered glass; it is aninvaluable test for identifying batches that have a high incidenceof nickel sulphide inclusions.
Product features:
1.about four times stronger than normal float glass of samethickness.
2.Better resistance to thermally induced stress.
3.Typically breaks into classic tiny piece pattern
4.Occasionally can experience spontaneous breakage due to nickelsulfide inclusion.
