Apparatus for the conditioning of fertilizers and/or other products to be used in particular in agriculture, permitting a regulated desorption of the fertilizers

摘要

Device for conditioning hydrosoluble fertilizers and/or hydrosoluble products usable in agriculture, wherein it comprises a sealed container, whereof at least one of the walls is constituted by a hydrophobic polymer diaphragm having hydrophilic inclusions, said container containing the fertilizers and/or products. A process for preparing a hydrophobic polymer diaphragm containing hydrophilic inclusions and usable in the conditioning device consists of preparing a hydrophobic polymer powder grafted by hydrophilic monomers and bringing this powder into the form of a diaphragm by different processes performed hot.
