What happened to the sun exposure of the French windows on the 18th floor? What goods should not be

The hot summer weather, let alone people, even glass can't stand it. There's news recently that because of the high temperature weather, what's the matter with the explosion of glass?

In recent days, the temperature is high, not only people can't stand it, but also a lot of goods begin to 'protest' the high temperature. Recently, the glass of a resident's house on the top floor of huajiayuan in Jiulongpo District 'exploded', and the glass debris fell from the 18th floor, damaging 5 cars downstairs.

Ms. Wu lives on the top floor (18 floors) of huajiayuan, Jiulongpo District.

On July 15, Ms. Wu found that the glass appeared to crack. She didn't care much at that time. Until the next day, the cracked glass broke suddenly, and with a sound of "crash", the whole piece of glass turned to pieces and fell from the 18th floor.

The broken glass smashed five parked cars downstairs. Worried that the broken glass would continue to fall, Ms. Wu called 119 to call the police. Fire officers and soldiers of Yangjiaping squadron of Jiulongpo District fire brigade rushed to the scene immediately for disposal. First, all the broken glass was glued with adhesive tape, and then slowly removed, so as to prevent large pieces of glass from falling down.

Ms. Wu said it took six firefighters more than three hours to clean up the broken glass while ensuring safety.

Firefighters and soldiers remind the public that in the coming tens of days of continuous sunny and hot weather, people with floor glass windows at home, as well as office buildings, should check the floor glass windows to eliminate hidden dangers.

It is suggested to pursue responsibility from the business

In response to this, the fire department said that Ms. Wu's high-rise home has good lighting. In recent high temperature weather, the outside of the window glass has been exposed to the sun for a long time, which can reach 65 degrees Celsius. The indoor air conditioner is always on, causing temperature difference between the inside and the outside. In addition, the quality of the glass is not very good, which leads to the occurrence of sunburn.

So is this going to happen to all the glass? A reporter from Chongqing Morning Post asked an insider who has been engaged in toughened glass business for a long time. According to reports, the root cause of self explosion of toughened glass depends on the original piece, because the original piece itself contains impurities -- nickel sulfide and bubbles, the more impurities and bubbles, the higher the self explosion rate.

According to the insiders, the glass of Ms. Wu's house will burst. The root cause is that there are many impurities and the quality of the glass is not good. It is suggested that Ms. Wu pursue responsibility from the merchants. Ms. Wu said that she was negotiating with the car owners about the specific compensation for five cars.

Remind these things not to be exposed to the sun

At present, it is in hot weather, and similar accidents are easy to happen. The Fire Department reminded that in addition to glass, these items should not be exposed to the sun in high temperature.

Vehicle - if the vehicle is exposed to the sun for a long time, damage will be caused to the vehicle if it is light, and accident will occur if it is heavy.

Lighter - the main component of the fuel in the lighter is butane, which will expand and explode when exposed to the sun.

Perfume - sealed perfumes are heated easily, and their essential oils are volatile to inflammable gases. The critical point of their combustion is 49 degrees Celsius. If the seal is intact, the bottle may burst under high temperature.

Flower dew -- it contains a lot of alcohol and other flammable liquids, which are easy to burn when meeting open fire after volatilization.

Vehicle mounted fire extinguisher -- the fire department reminds all car owners to purchase regular vehicle mounted dry powder fire extinguisher, and it is better to put the extinguisher in the trunk when parking to avoid direct sunlight.

Presbyopic glasses -- presbyopic glasses and magnifiers are convex lenses, which are easy to focus sunlight and ignite inflammables.

Carbonated drinks -- canned drinks containing compressed gas are easy to expand and deform under high temperature, and will burst in severe cases.

Yoghurt - yoghurt is a kind of milk product which uses fresh milk as raw material, ferments and then cools the filling. When the temperature of yoghurt is 2-6 ℃, the fermentation of Lactobacillus will be suspended. However, high temperature will lead to further fermentation of lactic acid bacteria in yoghurt and produce a lot of gas. When the gas in the bottle is too much and the pressure is large, it may cause explosion. Especially the glass bottle yoghurt, the power of explosion is very strong!

Power bank, battery - the battery pack in the power bank is mainly 18650 batteries or other lithium-ion batteries of other structures, which may explode under high temperature.

Smart phone -- the circuit board components of smart phones are very fine, some of which are not resistant to high temperature. In particular, smart phone capacitive screen parts are easy to be damaged due to high body temperature. When the cell phone battery is placed in a high temperature environment for a long time, there is a risk of bulging or even explosion. Mp3, digital cameras, tablet computers, notebook computers and other electronic products, as well as plastic toys, car CDs are easy to be damaged after a long time of exposure.
