[China Glass Network] Nowadays, tempered glass is used in many places, and even many of the entire building walls are made of tempered glass, such as the National Grand Theatre, the Apple Building on the Bund, and the high-rise buildings everywhere.
Tempered glass has high toughness, bending resistance, high safety performance and high light transmittance of ordinary glass. The country also insists that high-rise residential glass must use tempered glass, but although the name of the glass is added with tempered two Words, but it is not as strong as we think, tempered glass also has weaknesses, so pay attention to protection. If the protection is not good, the tempered glass will explode.
Method / step
1. Pay special attention to the corners of the tempered glass. If the corners of the tempered glass are damaged, the risk of self-explosion of such tempered glass will increase exponentially. Because the stress points of the tempered glass are all concentrated at the corners, it is necessary to protect the corners of the tempered glass. When the tempered glass with broken corners cannot be treated, it must be used with caution.
2, pay attention to avoid long-term tempered glass under pressure, some household tables, coffee table is made of tempered glass table top, the table will be under pressure, the general tempered glass withstand pressure between 70mpa to 100mpa, this pressure multiplied The area of ​​force on the glass is the greater pressure it can withstand. Converted to item quality = (pressure * area) / 10.
3, pay attention to avoid uneven heat and cold, it has been said that the internal stress points of tempered glass are all concentrated in the edge part. If, under extreme conditions, both ends of a piece of glass are subjected to high and low temperatures, then 90% of the glass will bleed spontaneously. For example, if a cold water is poured on a lit incandescent lamp, the glass of the incandescent lamp will rupture. Although this situation will be small for tempered glass, it is not afraid of 10,000.
4. Take care to avoid contact with the alkaline substances such as sodium hydroxide (NaOH) and hydrofluoric acid (HF). The glass is actually silica (SiO2), which will chemically react with the above substances.
5, pay attention to avoid using sharp objects or high-hard objects to violently tap the edges of the tempered glass.
