Parameters

Tempered Glass:

Toughened Glass Features: Ordinary float glass has strong compressive stress, but its tensile stress is very weak. Tempered glass is processed by rapid cooling the glass surface while heating the high quality float glass close to the softening point, so that the compressive stress distributes in the glass surface, and tensile stress is in the central layer. The two surfaces of toughened glass have strong and equal compressive stress, which enables the tensile stress generated by the external pressure to be offset by the strong compressive stress of the glass, thus increasing the strength and safety of the glass.

 

 

 

1.Strength Improvement: The mechanical strength, impact resistance and bending strength of tempered glass can reach 4-5 times that of ordinary glass. The strength test is to free fall 1040g steel ball from a height of 1 meter to the surface of the toughened glass and the toughened glass will not be damaged.

2.Improved Thermal Stability: Tempered glass can withstand huge temperature difference without damage, and its ability of resistance to variable temperature difference is three times of that of ordinary float glass with the same thickness . The test is to pour molten lead (327℃) on the surface of tempered glass at room temperature, and the tempered glass will not break.

3.Safety Improvement: After the toughened glass is damaged by strong force, it will quickly appear small obtuse angle particles, so as to ensure the maximum personal safety. That is, the number of particles in the broken tempered glass is greater than 40 in a 50-by-50-sized box.
