〔问〕什么是液化石油气? 〔答〕液化石油气的主要成分是丙烷和少量丁烷。丙烷、丁烷在常温常压下是气体,为了运输和使用方便,一般是加压后(8公斤/厘米~2)使它液化,装在特制钢瓶中运输使用,称为液化石油气。因其主要成分是丙烷,故也有称为丙烷液化气的,一些地区还简称为液化气。〔问〕液化石油气为什么能代替乙炔气进行钢材的切割和焊接呢? 〔答〕液化石油气主要成分是丙烷和丙烷的同分异构体丙烯,还有少量
[Q] What is liquefied petroleum gas? [A] The main components of liquefied petroleum gas are propane and a small amount of butane. Propane, butane gas at room temperature and pressure, for transportation and ease of use, usually after the pressure (8 kg / cm ~ 2) make it liquefied, packed in special steel cylinders for transport, called liquefied petroleum gas. Because of its main component is propane, it is also known as propane liquefied gas, some areas are also referred to as liquefied gas. Q: Why can liquefied petroleum gas instead of acetylene gas steel cutting and welding it? [A] liquefied petroleum gas is mainly composed of propane and propane isomers of propylene, as well as a small amount
