The ball surface coverage from polypropylene (PP) plastic material, the product comes in two models: I foamed float type, II type foamed solid core balls (energy saving ball).
isolation float ball  mainly used for ball covers over the upper level role. Such as: a storage tank for pH, acid gases can prevent spills, evaporation, reduce pollution and acid gases of the external environment, and the role of conservation acid-base materials; for the desalination of water, air, and water isolation can reduce air the CO2, O2 and dust and other impurities desalted water pollution and ensure water quality.
Suitable for a variety of horizontal acid storage tanks, water treatment condensate storage tanks, demineralized water tank, a large degree of reduction of acid mist in the air of carbon dioxide and oxygen in water pollution, protect water quality, energy conservation, clean environment effect.
