| titleOfInvention | Preparation method of formaldehyde purification material |
| abstract | The invention relates to a preparation method of a formaldehyde purification material, and belongs to the technical field of composite material preparation. The rush fibers are modified by adopting active carbon, and the washed rush fibers are impregnated by an active carbon dispersion system formed by mixing an organic solvent and the active carbon, so that the modified rush fibers are obtained. According to the invention, the three-dimensional network pore structure of the rush is utilized to adsorb the active carbon, the loading capacity of rush fibers to the active carbon is increased, and the problem of long purification time of the traditional active carbon is effectively improved by combining the high adsorption capacity of the rush. The rush fiber modified by the active carbon has the advantages of simple production process, short production flow, reduced environmental pollution, safety, energy conservation, economy, environmental protection and remarkable social and economic benefits. |
