眼下随着人民生活水平的提高,液化石油气的使用必将出现高峰。如何正确使用液化石油气,成为关系到人民生命安危的一件大事。液化石油气主要成分是丙烷(C_3H_8)、丙烯(C_3H_6)、丁烷(C_4H_1O)、丁烯(C_4H_8)。它在一定压力条件下变成液体,如果释去压力便转化成气体。1升液化石油气能挥发成约250升蒸气.如果在空气中达到爆炸极限范围内,只要拉一下电器开关,划一下火柴或遇其他明火,即刻便会引起燃烧爆炸,其爆速为2000～3000米/秒,火焰温度高达2000℃。不难看出,液化石油气的使用是极其危险的。我们在生活与工作中积
Right now with the improvement of people’s living standards, the use of liquefied petroleum gas is bound to peak. How to correctly use liquefied petroleum gas has become a major event concerning the safety of people’s lives. The main components of LPG are propane (C_3H_8), propylene (C_3H_6), butane (C_4H_1O) and butene (C_4H_8). It becomes liquid under certain pressure conditions, and is converted to gas if pressure is released. 1 liter of liquefied petroleum gas can be volatilized into about 250 liters of vapor. If the air reaches the limit of explosion, just pull the electrical switch, draw a match or other open flame, it will immediately cause a combustion explosion, the detonation rate of 2000 ~ 3000 M / s, flame temperature up to 2000 ℃. It is easy to see that the use of liquefied petroleum gas is extremely dangerous. We are plotting in life and work
