ARTIFICIAL TIMBER
20200115531 · 2020-04-16 ·

An artificial timber comprises the following components in parts by weight: 35-50 parts of cellulose, 20-35 parts of hemicellulose and 15-35 parts of lignin, wherein the artificial timber has a density of 0.01-0.05 g/cm.sup.3. The preparing method comprises: (1) dissolving 15-35 parts by weight of lignin, 35-50 parts by weight of cellulose and 20-35 parts by weight of hemicellulose with an ionic liquid; (2) cleaning and replacing it with water to obtain a lignocellulose hydrogel; and (3) drying the lignocellulose hydrogel to obtain an artificial timber. The artificial timber prepared by the present invention is large in specific area, low in density, low in material energy consumption, moderate in condition and easy for operation. The artificial timber obtained by the present invention is regular in shape and is shaped like a sandy beige cylinder without obvious damage and deformation, which indicates that such artificial timber with high specific area has well molding capacity.

Method for reducing the emission of volatile organic compounds made of wood materials, and wood materials

The present invention relates to a method for producing wood materials from lignocellulose-containing crushed products, in particular for producing wooden insulating panels or OSB boards, wherein in order to decrease or reduce the emission of volatile organic compounds (VOC) and, if relevant, very volatile organic compounds (VVOC), including terpenes, acids and aldehydes, said wood materials are treated with a combination of additives during production. According to the invention, the treatment is carried out with a first component made of porous carbon and a second component, a hydrogen sulphite salt. The invention further relates to wood materials that can be obtained using the method according to the invention, having reduced emissions of VOCs, including terpenes, acids and aldehydes. Finally the present invention relates to the use of a combination of additives, formed by a first component with a porous carbon and a second component made of hydrogen sulphide salt, for decreasing or reducing the emission of VOCs from wood materials during or after production thereof from lignocellulose-containing crushed products.
