Fully enclosed production  the production process is conducted in a closed tank, isolated from the outside world;the resulting acid mist is extracted from the tower and purified; Greatly reduce the pollution to the environment; Isolating the effects of the production on the operator's health;

Automatic operation  fully automatic operation can be chosen to produce continuously;High production efficiency, large output, especially suitable for large output, centralized production; Computer automatic control of process parameters, stable production process;

Significant economic benefit Automation control, stable process, large output, prominent efficiency and cost ratio;Less operators, low labor intensity; Good stability of the equipment, less vulnerable parts, very low maintenance;
