Effect of Dose Rate on Radiation Synthesis of Superabsorbent Resin

This research mainly is the study of absorbed dose rate on the performance of the two types of injectivity resin (water absorption performance, grafting rate). The experimental results show that the increase of the dose rate can be improved water absorbing ratio, grafting ratio and swelling ratio. Crosslinking agent used in this study is less, and low dose rate of experimental group could not complete the experiment. The synthetic injectivity resin cannot complete reaction when the dose rate is 1kGy/h. Field experiments show that water absorption resin for soil has obvious effect of water and promote the germination effect, soil moisture content as high as 17% after 15d, 15 to 20d extending irrigation cycle. Seed germination rate is over 93%.
