Method for preparing material for absorbing, storing and slowly releasing water and fertilizer by using desulfurized gypsum
The invention relates to the technical field of industrial solid waste resource utilization and novel environment-friendly material preparation, in particular to a method for preparing a material for absorbing, storing and slowly releasing water and fertilizer by utilizing desulfurized gypsum. The invention relates to a method for preparing a material for absorbing, storing and slowly releasing water and fertilizer by using desulfurized gypsum. The method comprises the following steps: step 1, preparing raw materials; step 2, mixing the raw materials; step 3, granulating the raw materials; the product provided by the invention has good water absorption, the volume is not changed before and after water absorption, and the soil structure is not influenced; after multiple times of water absorption, the repeated water absorption capacity is not reduced; the water absorption speed is high, the water absorption capacity is not affected by ions and soil components, and saline-alkali resistance, high temperature, ultraviolet rays and the like are achieved.
本发明涉及工业固废资源化利用以及新型环保材料制备技术领域，具体是一种利用脱硫石膏制备对水肥吸储和缓释材料的方法。一种利用脱硫石膏制备对水肥吸储和缓释材料的方法，包括步骤一：原材料制备，步骤二：原材料混合，步骤三：原材料制粒，步骤四：颗粒干燥，步骤五：颗粒高温烧制。本发明的产品具有较好吸水性,吸水前后体积不变，不影响土壤结构；多次吸水后，反复吸水能力不降低；吸水速度快，吸水能力不受离子及土壤成分影响耐盐碱、高温、紫外线等。
