Tempered glass, explosion-proof glass, use shower room with caution

Two days ago, citizen Fu Cheng took advantage of the weekend to purchase a shower room on Binhong Road. While passing by a bathroom store, he saw the owner arguing with a couple. After listening for a while, Fu Cheng understood the whole story: In October of this year, the couple bought a shower room at this store, but a few days ago, while taking a hot shower, the tempered glass door of the shower room suddenly burst The couple had several negotiations with the shop owner regarding this matter, but the handling result provided by the shop owner was far from their requirements, and both sides argued endlessly about it.

Can tempered glass also burst? This accidental discovery surprised Fu Cheng a lot.

Is tempered glass really prone to self explosion? What causes the glass door of the shower room to become a 'bomb'? The author conducted an investigation on this matter.

Customers often choose ordinary glass

Tempered glass does indeed self destruct

At the Binhong Road and Zhezhong Building Materials Market, the author found that glass shower rooms in the market are divided into two types according to quality: one is ordinary glass, which generally costs only a few hundred yuan each. It is said that the safety is poor and it is easy to burst when exposed to high temperatures, but more than half of Jinhua consumers want to buy ordinary glass shower rooms at a cheaper price; Another type is tempered glass, priced at nearly a thousand to tens of thousands of yuan. Many imitation orders or promotional materials for tempered glass shower rooms do not include a warning that 'tempered glass may burst', and salespeople only exaggerate its beauty and durability when selling, without mentioning the possibility of bursting.

A distributor who underwrites a well-known brand of shower rooms told me that their shower rooms are made of tempered glass with a thickness of 6 to 12 centimeters, and the glass has passed 3C certification to ensure safety. When asked if tempered glass can prevent bursting, the dealer admitted that tempered glass has a self explosion rate of about 3 ‰, and no one can guarantee 100% that it will not burst. However, in reality, the probability of tempered glass bursting is still relatively small.

The author asked several dealers of integrated shower rooms, and found that a self explosion rate of 3 ‰ has almost become a consensus, with some saying it is 1 ‰.

Why does tempered glass burst?

Technical staff analyze the reasons

It is understood that there are currently about ten tempered glass production enterprises in our city, and some of them also process shower rooms on behalf of others. A technician from a tempered glass factory, Xiao Chi, explained that tempered glass is heated to around 700 ℃ and then rapidly cooled to double its strength. Generally speaking, the strength of tempered glass is about 3 to 5 times that of ordinary glass. When tempered glass is shattered by external forces, it will turn into bean sized particles, thereby reducing harm to the human body. However, the seemingly simple craftsmanship requires strict standards, and if one step is not done properly, it can affect the degree of tempering of the glass, leading to incomplete tempering or even semi tempering. Due to the presence of some hard particles in the tempered glass, the probability of self explosion of the tempered glass increases.

A salesperson from a comprehensive shower room revealed to me that some tempered glass has self destructed due to the degree of tempering of the glass. Some small tempered glass production factories, including Jinhua, use defective glass or recycled glass for tempering, which greatly reduces the cost but lowers the quality.

Xiaochi believes that, excluding quality reasons, there are three other situations that may cause tempered glass to burst: improper use; Secondly, improper installation; Thirdly, the temperature difference is too large. So, when consumers use shower rooms at home, they should pay special attention to the environmental temperature difference and avoid strong external impacts.

Open the bathroom heater to preheat and improve the room temperature

Stick a layer of explosion-proof film on the glass door

In February of this year, Mr. Yu and his son from Yiwu City were taking a shower at a hotel near the International Trade City when the glass door of the shower room suddenly burst, and glass fragments splashed the entire bathroom. Mr. Yu and his son's limbs were also scratched by the broken glass. After mediation by the staff of Yiwu Consumer Protection Commission, the hotel compensated him with 4880 yuan for medical expenses and lost wages.

The Consumer Protection Commission of Yiwu City reminds citizens that the interaction between hot and cold air can easily cause tempered glass to burst. Citizens who have tempered glass shower rooms at home should turn on the bathroom heater first, preheat it, and raise the room temperature to prevent the glass shower room from bursting due to thermal expansion and contraction caused by hot water impact.

For shower room glass doors that may burst, some shop owners suggest applying film to the glass shower equipment. In case the glass bursts, it can greatly reduce harm to the human body.

The staff of Jinhua Consumer Protection Commission said that if tempered glass self destructs, the company should provide free repairs, and consumers should pay attention to the warranty period when purchasing. In general, the warranty period for shower rooms is one year. Consumers should not forget to request a repair order when purchasing.
