Способы изготовлени цветного пластика из опилок без св зующего Известны.Methods for making colored plastic from sawdust without a binder Known.
С целью получени водостойкой поверхности темно-коричневого цвета предлагаетс способ изготовлени щвегного древесного пластика из смеси опилок хвойных и лиственных пород. Сущность предложени заключаетс в том, что опилки с размером частиц 0,25-1 мм, содержащие 18-20% влаги, обрабатывают 5%-ным водны;м раствором сернокислого гидрокоиламина. Затем массу выдерживают в течение ,20-24 час дл прохождени процесса гидролиза. После чего полученную массу высушивают при температуре 60° до остаточной влажности 5-6% и подвергают гор чему лрессованию при температуре 150° под давлением 250 кг/см. Необходимое врем дл прессовани зависит от толщины древесного пластика « принимаетс равным одной минуте на каждый миллиметр толщины.In order to obtain a dark brown water resistant surface, a method is proposed for the production of magnet wood plastic from a mixture of softwood and hardwood sawdust. The essence of the proposal is that sawdust with a particle size of 0.25-1 mm, containing 18-20% moisture, is treated with 5% aqueous solution and hydroxylamine sulphate solution. Then the mass is kept for 20-24 hours to complete the hydrolysis process. After that, the resulting mass is dried at a temperature of 60 ° to a residual moisture content of 5-6% and subjected to hot compression at a temperature of 150 ° under a pressure of 250 kg / cm. The time required for pressing depends on the thickness of the wood plastic, being equal to one minute for every millimeter of thickness.
Изготовленный материал имеет гладкую, твердую, водостойкую поверхность те.мно-коричневого цвета. Такой древесный пластик и.меет следующие технические характеристики: Объемный вес- 1350 кг/м.The fabricated material has a smooth, hard, water-resistant surface of a dark brown color. Such wood plastic and has the following specifications: Volume weight is 1350 kg / m.
Предел прочности на сжатие - 500-800 кг/см. Коэффициент теплопроводности-0,258-0,267 ккал/м. град. час.Strength on compression - 500-800 kg / cm. Heat conductivity coefficient - 0,258-0,267 kcal / m. hail. hour.
Древесный пластик может быть использован как заменитель паркета и облицовочной керамики.Wood plastic can be used as a substitute for parquet and facing ceramics.
