Tempered Glass (Toughened glass)

  Tempered glass is one of two kinds of safety glass    regularly 
 
used in applications in which standard glass could pose a potential 
 
danger. Tempered glass is four to five times stronger than standard 
 
glass,it is manufactured through a process of extreme heating and rapid 
 
cooling, making it harder than normal glass. Tempered glass breaks in a 
 
unique way,it does not break into sharp shards when it fails,it becomes 
 
small obtuse angle pieces when broken. Thus people will not get hurt so 
 
much as ordinary glass.
      Hongjia Glass processed both heat-strengthened and fully tempered 
 
glass,both flat tempered glass and curved glass.
Fully-Tempered Glass
1,About 4-5 times stronger than normal float glass of same thickness
2,Better resistance to thermally induced stress
3,Typically breaks into classic tiny piece pattern
4,Occasionaly can experience spontaneous breakage due to nickel sulfide 
 
inclusion.
 But after heat soak,the self-explosion rate will be much lower.
Heat-Strengthened Glass
1,About two times stronger than normal float glass of same thickness
2,Good resistance to thermally loads than normal flat glass
3,Typically breaks into large pieces but heat-strengthened glass not 
 
easy to self-explosion,close to rate 0%.
4,Less prone to spontaneous breakage than tempered glass
Curved tempered glass
 Its arc should be part of a round circle,it doesn't need make a mold 
 
to start the production,but it needs adjust the machine to make 
 
required radian.
