Spray for a second and freeze?This kind of net red cooling "artifact" will really be "fire", and use it with caution in these cases!

Recent,

Multi -place encounters high temperature weather.

Under the hot sun,

Some car items,

Even the summer heat and cooling products,

Don't pay attention when you use it

It may become dangerous goods and cause accidents.

Burned during driving

The cooling spray is a "murderer"

At noon on June 25, 2022, Suzhou, Jiangsu,

A white private car suddenly stopped in the middle of the road,

The items on the car are scattered.

The police rushed to the scene and found it,

The two in the car were panicked,

Burned on the cheeks, arms, and other places.

At this moment, there is no bright fire in the car,

What did the two be burned?

It is understood that at that time, a net red spray that could be "freezed" in the car. Recently, the reporter searched on the e -commerce platform and found that the spray products of the slogan "Swelling, Quick Cooling" are seen everywhere, and some products have sold more than 10,000 a month.

In the publicity video of the online store,

The hot seat after exposure,

Easy to spray with this "summer artifact",

The whole car was immediately frozen.

Are these sprays so amazing?

The reporter purchased three products with the highest sales volume and brought them to the Chongqing Fire Brigade for experiments. Under the scorching sun, the outdoor temperature exceeded 38 ° C. The firefighters sprayed the three spray onto the fresh leaves. The surface temperature of the leaves quickly dropped below 0 ° C, and a layer of white frost was cited.

Huang Run, a firefighter for the Chongqing Fire Rescue Captain Life Division: We found that the most obvious effect can be instantly reduced to about minus 30 degrees Celsius, and a large area of ​​black spots appear on the leaves.

The subsequent car seat spray experiment also shows that these products can quickly drop the seat temperature from about 40 ° C to below 0 ° C.

How can such a "cooling artifact" become a "wounding weapon"? Firefighters simulated the people in the car to ignite when they used it, and found that the three sprayed white gas fogs were found. When they encountered bright fire, they immediately turned into the flames of the bears.

If they spray them on the skin, what happens when they encounter bright fires? Firefighters found three pigskin to simulate human skin. After spraying three types of cooling spray, the pig skin could be directly ignited. The severe burning flame quickly ignited the surrounding hair and continued to spread.

Huang Run, a firefighter for Chongqing Fire Rescue Captain Life Division: In the case of outdoor wind, the burning process of each pig skin lasted for more than five seconds. It can be seen that a large area of ​​burnt areas appeared on the pig skin. If it is ignited in a closed space in the car, it may occur, and the burns caused by human skin may be more serious.

Spray a lot in the car to cool down

The consequences of the fire are amazing

The reporter noticed,

In some online store promotional videos,

State claiming a lot in the car,

It can quickly reduce the temperature of the entire carriage,

And emphasize "physical cooling 0 harm".

Is this really the case?

Firefighters found a scrapped car for simulation test. In order to achieve the effect of cooling the entire carriage, firefighters sprayed a lot of cooling spray inside the car and windows. At this time, what would happen once in the car ignition smoking? Firefighters conduct simulation tests after safety protection. I saw that Minghuo was close to the vehicle, and a violent explosion occurred in the car.

The explosion not only caused the rear window glass to be blown up instantly, but the back row of the private car also burned a fire. Firefighters quickly found the fire extinguisher fire, and the car was still beyond recognition. In the event of someone in the car, the consequences are unimaginable.

What are the ingredients of these sprays, and why is there such a huge explosion power? The reporter carefully looked at the instructions of the three products, and found that two of them did not explain the ingredients. Only one said with cooling factor, edible fragrance, solvents, etc.

Professional instrument analysis ingredients

Open the "secret" of the cooling spray "secret"

None of the two cooling sprays are not marked with ingredients,

What is the so -called cooling factor?

The reporter found the Chongqing University Analysis and Test Center,

Use professional instruments to analyze product ingredients,

See these cooling spray

What kind of secrets are hidden.

Chongqing University Analysis and Test Center's temperamental use instrument can accurately analyze the composition and content of the spray. After testing the three cooling spray products, the experiment found that this black car special cooling spray was found. The main component was a substance called methar ether. The other two cooling spray contains the same three substances.

Qin Shijiang, an engineer of Chongqing University Analysis and Test Center: Two of the three products of the three products are propane, isopylene and orthopedane. It is actually a common liquefied petroleum and gas in our lives. The content is more than 90%. Explosion. The other content is mainly methyl ether, with more than 95%. Meethyl is also a flammable and explosive gas, which contains neurotoxicity. If a large amount of inhalation is prone to suffocation.

爆 ingredients

The packaging is not marked

According to reports, this type of cooling spray is to store these flammable and explosive gas stored in a metal tank by pressing liquefaction, and quickly vaporize and absorb the surrounding environmental heat to achieve rapid cooling. More than 90%of the flammable and explosive ingredients, but the three products are not mentioned, and similar situations are not individual.

Recently, the Shanghai Municipal Consumer Protection Commission commissioned professional institutions to evaluate 10 such hot -selling products on the Internet and found that four of them did not indicate product components. For the flammable testing of the product, four of the 10 samples were 90 cm away from Minghuo, which can be quickly ignited. It is a type of flammable product. The distance of more than 15 cm should be indicated that the two types of flammable logos should be marked, but no packaging appears. Duan Road, senior engineer of the Shanghai Chemical Research Institute of Chemical Engineering Institute: According to relevant standards, flammable liquid and gas solution should be clearly identified and prompting their flammable categories in the product label. The situation is more common.

Even if you don't encounter Minghuo

It will explode at high temperature

Such dangerous products,

Even if you don't encounter Minghuo,

High temperature weather stays in the car

There are also huge risks.

At about 12 noon on the same day, Chongqing's outdoor temperature exceeded 38 ° C. Firefighters conducted three spray -in -car storage experiments.

After the door was closed, about 25 minutes, a bottle of blue cooling spray exploded first. A circular burst of about 20 cm in diameter was blown on the windshield, and the spray next to it was also bounced. After 7 minutes, another cooling spray left on the instrument also exploded.

Will the bounce black cooling spray safety be higher? Firefighters subsequently found three common high -pressure spray products in life, including air fresh agents, sunscreen spray and hydrating spray, and put into the car with a new black cooling spray in the car for a comparison test. Under the scorching sun, the temperature of the inner instrument platform exceeded 80 ° C, and the black cooling spray insisted on the first explosion for only 23 minutes.

Not only did the windshield exploded a large hole, but the spray next to it was also blown up instantly.

Qin Shijiang, an engineer of Chongqing University Analysis and Test Center: This kind of product is more dangerous than the cosmetics spray and moisturizing spray we usually use. Because the cosmetics spray contains a lot of water, this category is almost composed of pure flammable and explosive gas, which is easier to explode.
