乙炔气又叫电石气。乙炔不但是重要的化工原料,而且广泛地用于气焊、气割、加热和照明等作业之中。化工原料用乙炔,是由大型固定式乙炔发生器制取的;热加工和照明等用乙炔,是由小型移动式乙炔发生器(俗称电石罐)制取的。 现在,随着科学技术和工业生产的发展,已经开始不用小型移 Acetylene gas is also called calcium carbide gas. Acetylene is not only an important chemical raw material, but also widely used in gas welding, gas cutting, heating and lighting operations. Acetylene for chemical raw materials is made from large fixed acetylene generators; acetylene for thermal processing and lighting is made from small mobile acetylene generators (commonly known as calcium carbide pots). Now, with the development of science, technology and industrial production, no small-scale shift has begun
