How much effect does it prevent the spread of the fire
March 13, Jiashan fire rescue personnel
Through Burning comparison experiment
Let the masses feel more intuitively
Fire products quality </
The importance of safety supervision
The experimental site is a laboratory of about ten square meters, the laboratory There are two electric vehicles in the inside. And combustion tests on them to simulate the fire resistance of the two doors when the fire is fired. -Spacing: 1.5px; \”> 10 minutes see the division, what is the burning?
At the scene, fire rescue workers prepared a laboratory about 10 square meters and from left to right in the same side from left to right. The ordinary wooden doors, fire doors and aluminum -plastic frame glass doors are installed in order.
The experiment passed the combustion test , Test the difference between ordinary wooden doors and aluminum -plastic frame glass doors and qualified fire doors in fire resistance.
> At the beginning of the experiment, the firefighters ignited the two electric vehicles indoors. Through the window of the glass door, the fire was clear and the fire was clear. //p3-sign.toutiaoimg.com/tos-cn-i-6w9my0ksvp/0c3dfa19016d44a780af40d500625e0c~tplv-tt-origin-web:gif.jpeg?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1739326434&x-signature=Q1XKVNujpJii36zmE% 2Fe%2F%2FkMJf9o%3D\”/>
2分鐘過去，經測溫，三扇門的溫度差異逐漸顯現， The temperature of ordinary wooden doors and glass doors is 35 ° C and 43 ° C, while the temperature of the fire door is only 21 ℃, its thermal insulation effect has begun. /span>
6 minutes and 45 seconds, The ordinary wooden door has been burned on a large area, The temperature is 50 ° C.
8 points In 16 seconds, the heat resistance of the aluminum-plastic frame glass door reached the limit, /span> At this time, the temperature of the fire door is about 90 ° C.9MY0KSVP/451B05B164404BD41A91CBF800C7ce ~ TPLV-TT-Origin-Web: GIF.JPEG?

In 10 minutes, ordinary wooden doors and glass doors have been burned, leaving only their door frames, The fire door is always\” strong \”, only a small amount of flue gas is spreading out at the door seam. src = \”https://p3-sign.toutiaoimg.com/tos-cn- I-6W9MY0KSVP/F5DEA2BD01E9484B8C448ADC269A1525~tplv- origin-Jpeg?_iz=58555555555 8 & from = article.pc_detail & lk3s = 953192F4 & X-EXPIRES = 1739326434 & X -signature = cpgwbvkraygx7v1jfzui3hdqla4%3d \”/>
It can be seen that a qualified fire door is really important! </span!
3 minutes, the fire door smoke problem is displayed!
Whether the closed fire door is closed, the firefighters chose a 4-story waste plant as an experimental location. Color: #C52424; \”> Adjust the fire door on the third floor of the factory building into an open state, and the on the fourth floor is closed.
After the electric vehicle parked in the stairwell was ignited, a violent burning occurred, and a large amount of flue gas quickly followed the corridor quickly. Prove upward

1 minute 10 seconds, Toxic flue gas constantly pouring from the fire door opened from the third floor, spreading around the naked eye.
3 minutes, Third Floor The flue concentration is getting worse, it has long been \” Do not see five fingers \”. and Four Building Due to the closing state of the fire door, smoke is effectively blocked, The sewage of the door and the window is less, The overall visibility is high. -I-6W9MY0KSVP/010004A0A8CD435DA83D51378B38C711 ～ TPLV-TT-Origin-WEB: GIF.JPEG? _IZ = 58558 & From = Article.pc_detail & LK3S = 953192F4 & & & & & & & & & & & & & & & & &Detail X-EXPIRES = 1739326434 & X-Signature = E%2figxz5zgas2jea8nneppkpthum%3d \”/>
At this time, observed from the outside of the plant, it is also a high judgment, Three-layer windows have a large amount of black smoke rushing to the valga, and the four layers are slightly\” calm and quiet \”.
