Abstract
Description
Изобретение относится к деревообрабатывающей промышленности, в частности к производству древесноволокнистых плит. The invention relates to the woodworking industry, in particular the production of fiberboards.
Известен также способ производства строительной плиты из отходов хлопкоочистительных заводов, включающий операции приготовления массы, введения упрочняющих добавок, формирование ковра и горячее прессование. There is also known a method of manufacturing a building board from the waste of ginneries, including the operations of mass preparation, the introduction of reinforcing additives, carpet formation and hot pressing.
Недостатком известного способа является низкая прочность плит, сильное разбухание по толщине и высокая их себестоимость. The disadvantage of this method is the low strength of the plates, a strong swelling in thickness and their high cost.
Цель изобретения - повышение прочности при изгибе и снижение разбухания по толщине. The purpose of the invention is to increase bending strength and reduce swelling in thickness.
Поставленная цель достигается тем, что в способе изготовления плитного материала из отходов хлопкоочистительных заводов, приготовлением волокнистой массы, введением упрочняющей добавки, формированием ковра, горячим прессованием и термообработкой готовых плит, в качестве упрочняющей добавки используют хлопковый гудрон, а введение упрочняющей добавки осуществляют пропиткой отпрессованных плит в растворе хлопкового гудрона концентрацией 1-8% , при комнатной температуре в течение 3-5 мин. Хлопковый гудрон (смолу госсиполовую) получают при дистилляции жирных кислот из хлопковых соапстоков и применяют в качестве сырья в дорожном строительстве, лакокрасочной промышленности и др. Смола - однородная, вязкотягучая масса от темно-коричневого до черного цвета. This goal is achieved by the fact that in the method of manufacturing plate material from the waste of ginneries, preparing pulp, introducing a reinforcing additive, forming a carpet, hot pressing and heat treating the finished plates, cotton tar is used as the reinforcing additive, and the introduction of the reinforcing additive is carried out by impregnation of pressed plates in a solution of cotton tar with a concentration of 1-8%, at room temperature for 3-5 minutes Cotton tar (gossypol resin) is obtained by distillation of fatty acids from cotton soap stocks and is used as a raw material in road construction, paint industry, etc. Resin is a homogeneous, viscous mass from dark brown to black.
Характеристики хлопковых гудронов представлены в табл. 1. Characteristics of cotton tar are presented in table. 1.
П р и м е р. Массу для изготовления плит из отходов очистки хлопка приготавливают в ролле путем размола при температуре 50-60оС и концентрации 2-4% , причем упрочняющие и гидрофобные добавки в нее не вводят, а затем направляют ее на формирование ковра. Горячее прессование плит осуществляют в гидравлическом прессе при температуре 190-200оС и давлении 4,2-5,5 МПа.PRI me R. The mass for the manufacture of plates from cotton cleaning waste was prepared by milling in a roll at a temperature of 50-60 ° C and a concentration of 2-4%, the hardening and hydrophobic additives are not introduced into it, and then send it to form a carpet. Hot pressing plates is carried out in a hydraulic press at a temperature of 190-200 C and a pressure of 4,2-5,5 MPa.
Отпрессованную плиту пропитывают щелочным раствором хлопкового гудрона (ОСТ 18-114-73) с концентрацией 0,7% в течение 2,5 мин. The pressed plate is impregnated with an alkaline solution of cotton tar (OST 18-114-73) with a concentration of 0.7% for 2.5 minutes.
Пропитанную плиту обрабатывают в среде горячего воздуха при температуре 160-170оС в течение 3,5-5 ч, а затем увлажняют до влажности 3-4% и раскраивают по формату.The impregnated board was treated in a hot air environment at a temperature of 160-170 C for 3.5-5 hours, and then is moistened to a moisture content of 3-4%, and are cut to the size.
Параметры проведения способа по примерам приведены в табл. 2. The parameters of the method according to examples are given in table. 2.
Физико-механические показатели изготовленных плит приведены в табл. 3. Physico-mechanical properties of the manufactured plates are given in table. 3.
