Abstract
Description
Изобретение относится к производству строительных материалов и может быть использовано для изготовления лигноуглеродных древесных пластиков. The invention relates to the production of building materials and can be used for the manufacture of ligno-carbon wood plastics.
Известна масса для изготовления лигноуглеводных древесных пластиков, содержащая измельченную древесину хвойных пород (1). Known mass for the manufacture of ligno-carbohydrate wood plastics containing crushed coniferous wood (1).
Недостатком этой массы является низкая прочность и водостойкость получаемых из нее пластиков. The disadvantage of this mass is the low strength and water resistance of plastics obtained from it.
Наиболее близкой к предлагаемой по технической сущности является смесь для изготовления древесно-стружечных плит, содержащая в своем составе древесные частицы и белки растительного происхождения (2). Closest to the proposed technical essence is a mixture for the manufacture of chipboards, containing wood particles and proteins of plant origin (2).
Однако получаемые из смеси плиты недостаточно прочны и водостойки. However, the plates obtained from the mixture are not strong enough and waterproof.
Целью изобретения явилось повышение прочности и водостойкости древесных плит. Эта цель реализуется за счет того, что пресс-масса для изготовления древесных плит, содержащая измельченные древесные частицы и белковую добавку, в качестве белковой добавки содержит инокулюм гриба Ptigrinus-144, при следующем соотношении компонентов, мас.%: измельченные древесные частицы 85-91; инокулюм гриба Pti grinus 144 - 9-15. The aim of the invention was to increase the strength and water resistance of wood boards. This goal is achieved due to the fact that the press mass for the manufacture of wood-based panels, containing crushed wood particles and a protein supplement, contains a Ptigrinus-144 fungus inoculum as a protein supplement, in the following ratio of components, wt.%: Crushed wood particles 85-91 ; inoculum of the fungus Pti grinus 144 - 9-15.
Инокулюм гриба - это раствор питательной среды и грибного мицелия. Inoculum of the fungus is a solution of a nutrient medium and mushroom mycelium.
Инокулюм гриба получают выращиванием культуры на жидких питательных средах предпочтительно при температуре 29оС в течение 6 сут.The inoculum of the fungus is obtained by growing the culture on liquid nutrient media, preferably at a temperature of 29 about C for 6 days.
П р и м е р ы 1-5. Инокулюм вносят в предварительно измельченное древесное сырье, тщательно перемешивают, сушат до влажности 8-12%, формируют ковер холодной подпрессовкой и подвергают горячему прессованию при 180-190оС и давлении 2,5-3 МПа в течение 0,9 мин/мм толщины изделия.PRI me R s 1-5. The inoculum is introduced into pre-comminuted wood raw material, thoroughly mixed, dried to a moisture content of 8-12%, cold prepressing form a carpet and subjected to hot pressing at 180-190 ° C and a pressure of 2.5-3 MPa for 0.9 min / mm thickness products.
Пример 6 выполняют по аналогичной технологии при использовании в качестве добавки растительных белков. Example 6 is performed by a similar technology when using vegetable proteins as additives.
Составы пресс-масс по примерам 1-6 и физико-механические показатели получаемых изделий представлены в табл. 1 и 2. The composition of the press mass according to examples 1-6 and physico-mechanical parameters of the resulting products are presented in table. 1 and 2.
