China's largest trona comprehensive processing project - Henan Tongbai annual production of 1.5 million tons of soda ash, sodium bicarbonate (baking soda) project started construction recently. After the project is put into production, the annual production capacity of alkali in Tongbai area will be nearly 3 million tons, and it will become one of the world's natural alkaloid alkalis. Tongbai County's natural alkali comprehensive processing project adopts the world's leading sesquisive process liquid phase water chemistry, one-water method, carbonization and other production processes, as well as deep-seabed fracturing connectivity and solution mining, and 14 international patented technologies, which are manufactured in China. For the first time, the alkali industry achieved zero discharge of sewage. The project also plans to achieve an annual production scale of 5 million tons in the future. The project produces heavy soda ash. At present, the heavy soda ash produced in developed countries is more than 80% of the total soda ash production, while China's heavy soda ash has only 33% of total production. After the project is put into production, it will have a positive impact on the adjustment of the product structure of the soda industry.

which is rust-proof and beautiful. Moreover, the important parts of the force are treated with process
mechanics, and the bearing capacity is greatly enhanced. Oxford cloth specifications are mainly 600D
or 800D, and most folding beds use a double-layer cloth structure, which improves the service life and
comfort of the seat surface. The folding link parts are linked with galvanized rivets and original plastic
parts, which are added according to the characteristics of different products, such as the design of the
