Fuente: WIPO "industrial hemp" The invention discloses a high-strength inorganic artificial board and a manufacturing method thereof. The method comprises the following steps of: crushing industrial hemp stems into shavings or preparing industrial hemp stems into fibers, mixing the shavings or the fibers and an inorganic material uniformly, adding a retarder, a mineralizing agent, an adhesive and water, and preparing the mixture into the artificial board by a wet method, a semidry method or a dry process. Conventional wood shavings or fibers can be added into the raw materials. The inorganic artificial board is manufactured by using the characteristics of high strength and good toughness of the industrial hemp stems for the first time; and the manufactured inorganic artificial board has the properties of low density, high strength and good bearing performance. The technology can be implemented to remarkably save the wood resources and protect the ecological environment, changes wastes into valuable, provides a new path for the application of the industrial hemp, is favorable for promoting the further development of the industrial hemp industry, and has good social benefit and economic benefit.
