Then, during the use of foam caulking, there are some safety hazards that we must pay attention to. For example, the storage of foam caulking must be done inDry, cool and ventilated place to avoid the risk of leakage or explosion. So, Why do foam caulking tanks explode when exposed to high temperatures or open flames? Woolen cloth?

The author saw a news on the Internet today, An 11year-old boyUnfortunately, an accident happened while playing with my friends, resulting in serious burns on my face and right hand, the culprit is foam caulking.

It is expected that 4 skin grafting surgeries will be required.
WhyFoam caulking agent tanks will explode when exposed to high temperatures or open flames
PolyurethaneFoam caulkCanned is generally an alkane gas. Commonly used ones are propane and dimethyl ether, butane gas Mainly used for pressure ejection. As we all know, gas will expand when heated, which is the principle of thermal expansion and contraction, and is a physical reaction.Objects expand when heated,will shrink when exposed to cold , This is because the movement of particles (atoms) in the object changes with temperature, When the temperature rises, The vibration amplitude of the particles increases,Inflate objects;But when the temperature drops,The vibration amplitude of the particles will be reduced,make the object shrink. Therefore, the foam caulking tank will ignite when exposed to high temperatures, expand and explode. Pluspropyl butane and dimethyl etherThey are all flammable gases and will encounter open flamesEasy to burn and explode, so you must not be careless in storing foam caulking, and you must use foam caulking correctly and keep away from children to avoid unnecessary trouble.
About whyThe author will tell you so much about the problem that foam caulking tanks will explode when exposed to high temperatures or open flames. If you want to know more about foam caulking, please pay attention to Shanghai Weigu.
