Glass surface material stage of toughened glass - why
Jiangsu city Shizhan Truss co. , LTD
Stage according to the different demand, can choose different stage, stage of conventional plate using 18 mm checkered plate, even rainy days use is ok.
Some catwalk stage or the concert stage, for example, will use glass stage, transparent glass can give a person feel not strong enough, on the top is not steadfast, but in fact this is an illusion, let me take you to understand the glass plate, for everyone to meet again.
Stage of the glass is we often say the toughened glass, toughened glass is what?
Toughened glass is glass of a kind of prestressing force actually, use the method of chemistry or physics normally, form in vitreous surface press stress, glass bears offset above all when outside force surface layer stress, so as to improve the bearing capacity, improved vitreous tensile strength.
Toughened glass stage there are two main advantages: one, the bending strength is common glass 3 -
Five times the impact strength is common glass 5 -
Second, increase the carrying capacity of brittle quality is improved, even small shards of toughened glass damage has no acute Angle, greatly reducing the harm of human body, the stress on the surface of the 69 mpa, general can withstand more than 150 degrees Celsius temperature changes, have apparent effect to prevent thermal cracking.
Use tempered glass, toughened glass stage its strength is higher than common glass.
Some manufacturers also use tempered glass, glass between the properties of toughened glass and common glass between note that aggrandizement glass do not belong to the scope of safety glass, the once broken, there is still a sharp debris.
So everybody glass products when the choose and buy must ask businessman is toughened glass or tempered glass.
The glass heating stage of toughened glass steel principle, and then after rapid cooling (
A bit like metal quenching)
Glass inside have a lot of tensile stress, and generate greater compressive stress on the surface.
Its role as the prestressed reinforced concrete members by using steel will produce a compressional stress on the need to strengthen.
, prestressed concrete will produce a compressional stress only in part area, and toughened glass is in all the surface compressive stress.
Glass steel quenching process and hardening process of metal surface hardening treatment is different also.
Of toughened glass processing, there is no hardening was carried out on the glass surface, thus toughened glass, resistance to abrasion, scratch the surface of the ability is not improved obviously.
