Abstract:
     The high water-absorption materials are made from traditional chemical raw materials with a chemical methods. Those processes are complex and costlier. In this invention, a new irradiation method which is used for preparing super-complex water-absorption materials is investigated. In this method the bentonite is used. The cost is less. The process is simple and causes no pollution. The water-absorption materials can meet various demands for keeping water in the soil, blocking water in the oil field and daily utensils and it's multiples of water-absorption can be controled.
