Recently, the market range of flake alkali in East China has decreased. Some local factories produce flake caustic soda, and the overall supply scale is small. Most of the supply sources are supplemented by the northwest supply source. The downstream of flake alkali is mainly concentrated in alumina, textile, printing and dyeing, chemical industry and other industries, and the transactions are mainly fixed long-term contracts. At present, with the increase of the epidemic scale, the downstream consumption capacity is shrinking. In addition, the main downstream alumina has been continuously reduced, and the transaction price of flake alkali is lower. Compared with last week, the underground adjustment range is 500-600 yuan / ton.
