On May 23, the 100000 ton evaporation and 50000 ton flake caustic soda project of Sichuan xinshengyuan Chemical Co., Ltd., which was contracted by Chongqing Bozhang, was successfully started at one time. One belt, one road, is the annual production of 100 thousand tons of ionic membrane caustic soda in salt chemical industry, Dechang, Sichuan. It is one of the key projects to accelerate the integration of the "one belt and one road" construction. The total area is 79900 square meters, which has an important economic promotion role in strengthening the exchange and cooperation between Panxi economic zone and the ten ASEAN countries. It is also the Sichuan Xin Sheng Yuan Chemical Co., Ltd. to optimize the product mix. Promote industrial upgrading and build a new chemical production base in Xichang City, Liangshan Prefecture, Sichuan Province. The 50000 ton flake caustic soda plant in the project is the first one to produce flake caustic soda in this area, and the electric heating flake caustic soda system used is the second one in China so far. The formal commissioning and completion of the project enriches the supply and demand of the upstream and downstream of the geo economy and makes a great contribution to the local economic benefits. The project will be installed in mid December 2020 and put into production in May. Affected by the local climate, the site construction conditions from January to March are very bad and the construction is very difficult. In order to ensure the rapid implementation of the project, after the restoration of construction conditions, the technical teams of Sichuan xinshengyuan and Chongqing Bozhang cooperated closely, planned scientifically and organized meticulously, and completed the construction and commissioning of the project in only two months. With a high sense of responsibility and cooperation spirit, the project goal of "high efficiency, safety, professional and high quality" was achieved.
