COMPOSITIONS FOR ARTIFICIAL AGGREGATES FOR ORCHID CULTURE AND ITS MANUFACTURING METHOD

摘要

PURPOSE: An orchid stone composition using waste shells, and a manufacturing method of orchid stones are provided to enhance water-absorption force, permeability, detergency and antibacterial properties. CONSTITUTION: An orchid stone composition using waste shells comprises 50-84 wt% of waste shells having the particle size of 30-90 meshes, 10-50 wt% of inorganic binder, and 5-20 wt% of metal oxide. A manufacturing method of orchid stones comprises the following steps: pulverizing waste shells(S110); removing organic materials by sintering the waste shells(S120); dipping the waste shell powder into a silver nitrate, silver sulfate, or perchloric acid solution(S130); drying the dipped waste shell powder(S140); mixing the dried waste shell powder, the inorganic binder and the metal oxide(S150); manufacturing the mixture of the previous step into a molded product for the orchid stones(S160); and sintering the molded product(S170).
