Abstract
1. Пресс-масса, содержащая частицы растительного сырья, имеющие в своем составе целлюлозу, лигнин, гемицеллюлозы, свободные сахара, полученные из углеводной части растительного сырья при его кавитационной обработке без и с добавлением гидролизующего агента в количестве 1 мас.ч на 100 мас.ч. лигноцеллюлозного материала. ! 2. Пресс-масса по п.1, отличающаяся тем, что в качестве растительного сырья она содержит материал, выбранный из группы, содержащей измельченную древесину, солому злаковых и др. ! 3. Способ получения пресс-массы, включающий кавитационную обработку растительного сырья без и с добавлением гидролизующего агента, отличающийся тем, что для реализации многократно и быстроизменяющихся условий используют устройства, генерирующие в реакционной массе кавитационные процессы, при которых происходит разрушение клеточной стенки без существенной деструкции основных структурных компонентов, сопровождающееся образованием биомассы, которая может быть использована для получения плитных материалов. ! 4. Способ получения плитных материалов на основе пресс-массы по п.1, содержащей целлюлозу, лигнин, гемицеллюлозы, свободные сахара и продукты их термодеструкции, включающий формование ковра, холодную подпрессовку и горячее прессование, отличающийся тем, что горячее прессование осуществляют при 120-160°С и давлении 2,5-11 МПа при влажности ковра 5-20%, также возможна модификация плитных композиций.1. A press mass containing particles of plant material containing cellulose, lignin, hemicellulose, free sugars obtained from the carbohydrate part of plant material during its cavitation treatment without and with the addition of a hydrolyzing agent in an amount of 1 wt.h. per 100 wt. h lignocellulosic material. ! 2. The press mass according to claim 1, characterized in that, as a plant material, it contains a material selected from the group consisting of ground wood, cereal straw, etc.! 3. A method of obtaining a press mass, including cavitation processing of plant materials without and with the addition of a hydrolyzing agent, characterized in that for the realization of repeatedly and rapidly changing conditions, devices are used that generate cavitation processes in the reaction mass, in which the cell wall is destroyed without significant destruction of the main structural components, accompanied by the formation of biomass, which can be used to obtain plate materials. ! 4. The method of obtaining plate materials based on the press mass according to claim 1, containing cellulose, lignin, hemicellulose, free sugars and products of their thermal degradation, including carpet molding, cold pressing and hot pressing, characterized in that hot pressing is carried out at 120- 160 ° C and a pressure of 2.5-11 MPa with a carpet moisture of 5-20%, modification of plate compositions is also possible.
