Tempered glass is safety glass, created by heating float glass to ~620°C then rapidly cooling it. This thermal tempering induces surface compression and core tension. Challenges include roller wave distortion and NiS inclusion risks. Tempered glass's key advantage is its safety: upon breakage, it fragments into small, blunt granules instead of sharp shards, significantly reducing injury risk. It's also stronger and more heat-resistant than annealed glass.
1.Characteristics & Process: Defines it as safety glass, mentions the core thermal tempering process (heating + rapid quenching).
2.Problems: Highlights common production issues (roller wave, NiS inclusions).
3.Key Advantage: Emphasizes the critical safety benefit (harmless granules) and mentions added strength/heat resistance vs. standard glass.
