20 世纪 80 年代末，中国开始了公路的大发展，与此同时，桶装固态沥青也被大量的使用。但在沥青脱桶过程中，出现了一系列的问题：高能耗、高污染、高劳动强度、低效率……In the end of 1980s, China began to develop road on a large scale. At the same time, the drummed solid asphalt was vast demanded. In the process of decanting and heating up the drummed solid asphalt, many serious problems occurred, such as high cost, vast waste, high pollution, low efficiency, and so on.为了尽快解决这些问题，达刚公司通过多年努力，于 1988 年研制成功世界上第一台利用燃气废气及导热油加热的沥青脱桶设备，彻底解决了桶装沥青脱桶加热的问题！In order to solve these problems, Dagang company developed the first drummed asphalt decanting equipment with the features of using the Burner’s hot gas to decant and using thermal oil to heat up.
