Study on Water Evaporation Retardant under Natural Environment
The film material of water evaporation retardants was prepared with hexadecanol. Emulsion system was compared with solution system on the ability of water evaporation under natural environment. The effect factors of the film surface concentration and water temperatures on retardation of water evaporation were tested. The biological degradation and practical application of insoluble film were discussed. The results show that the percentage resistance of emulsion system is still about 50% after 15 days under natural environment, while the film surface concentration is 0.8 g/m2. Besides,the insoluble film from the emulsion system has the ability of anti - temperature interference and of biological degradation.
