Description
Известны способы изготовлени заменителей лесоматериалов гор tiiiM прессованием древесных опилок и стружек со св зующими веил.ествами , например с различными си1 тетическими смолами.There are known methods for making wood substitute materials for mountain tiiiM by pressing sawdust and wood shavings with bonding materials, for example, with various synthetic resins.
Описываемый способ предлагает изготовление прессованных изделий из древесных и других растительных отходов без применени синтетических смол .The described method proposes the manufacture of extruded products from wood and other plant waste without the use of synthetic resins.
С этой целью воздушно-сухие отходы, например древесные опилки, смешиваютс с 8-10% элементарной серы и затем обрабатываютс таким количеством слабого раствора сол ной кислоты, которого должно быть достаточно дл пропитки всей массы опилок. Нужное количество раствора устанавливаетс путем предварительного определени влагоемкости опилок.To this end, air-dry waste, such as sawdust, is mixed with 8-10% elemental sulfur and then treated with such a quantity of a weak solution of hydrochloric acid, which should be sufficient to impregnate the whole mass of sawdust. The required amount of solution is established by pre-determining the moisture capacity of the sawdust.
Концентрированна сол на кислота дл приготовлени раствора беретс из такого расчета, чтобы количество ее (в пересчете на 100%-ную кислоту) было не меньше 1,8% и не больше 2% к весу обрабатываемых опилок. После такой обработки опилки высушиваютс до содержани влаги 5-7%.Concentrated hydrochloric acid for preparation of the solution is taken from such a calculation that its amount (in terms of 100% acid) is not less than 1.8% and not more than 2% by weight of the treated sawdust. After this treatment, the sawdust is dried to a moisture content of 5-7%.
Далее в опилочную массу добавл етс 1% сол рового или любого другого нефт ного масла, необходимого дл того, чтобы плиты или другие издели при прессовании не прилипали к формам. Полученна комцозици прессуетс в течение 15-20 мин. в формах под давлением 50-55 кг/см при температуре 115-120°.Next, 1% of salt or any other petroleum oil is added to the sawdust, so that the plates or other products do not stick to the molds during pressing. The resulting composition is pressed for 15-20 minutes. in forms under pressure of 50-55 kg / cm at a temperature of 115-120 °.
По данным проведенных испытаний в лаборатории прессованные плиты имеют следующую характеристику:According to the tests conducted in the laboratory, pressed plates have the following characteristics:
1.Водопоглощение за 3 суток-от 1,5-7,0%1. Water absorption in 3 days - from 1.5-7.0%
2.Прочность на изгиб и раст жение - 120-150 кг./слг-.2. Bending and tensile strength - 120-150 kg. / Slg-.
№122601- 2 -No. 122601-2 -
3. Водоустойчивость-после насыщени водой издели в объеме не увеличиваютс и указанные выше свойства не измен ютс .3. Water-resistance — after saturation of the product with water, the volume does not increase and the above properties do not change.
Прессованные по предлагаемому способу плиты и другие издели пригодны дл настила чистых полов жилых и общественных зданий, изготовлени дверных филенок, дл отделки мебели и других различных поделок.The plates and other products pressed by the proposed method are suitable for laying the clean floors of residential and public buildings, making door panels, for finishing furniture and other various handicrafts.
Предмет изобретени Subject invention
Способ изготовлени строительных изделий из древесных и других растительных отходов, например, из опилок с добавками, путем гор чего прессовани , отличающийс тем, что, с целью повышени водостойкости и прочности изделий, а также их удешевлени , взамен добавки синтетических смол, отходы смешивают г 8-10% -серы по &есу, пропитывают слабым раствором сол ной кислоты и высушивают до влажности 5-7%, после чего добавл ют сол рового или другого нефт ного масла в количестве 1 % по отношению к высушенной смеси и затем эту смесь подвергают гор чему прессованию.A method of manufacturing construction products from wood and other plant waste, for example, from sawdust with additives, by hot pressing, characterized in that, in order to improve the water resistance and durability of the products, as well as reduce their cost, instead of adding synthetic resin, waste is mixed g 8 -10% sulfur &, impregnated with a weak solution of hydrochloric acid and dried to a moisture content of 5-7%, after which salt or other petroleum oil is added in an amount of 1% relative to the dried mixture and then this mixture is subjected what the hell ressovaniyu.
