摘要
Abstract
Waste rubber recycle is a preferential development direction to promote the development of rubber industry and to improve environment management level. Producing fine powder by cryogenic comminution is the most promising method for rubber recycle. The present paper summarizes the progress in rubber cryogenic comminution, including refrigeration techniques with liquid nitrogen, air expansion, ammonia-ethane, natural gas under high pressure expansion and liquefied natural gas cryogenic energy. Most of these techniques are encountered with many difficulties such as high energy consumption, product quality control as well as dust pollution etc. Hence, the present paper proposes a waste rubber cryogenic comminution technique using liquid refrigerant and liquefied natural gas as the cold source, which may have some merits such as lower energy consumption, better product quality control and dramatically reduced dust pollution and so on.关键词
