Description
(54) СПОСОБ ИЗГОТОВЛЕНИЯ ПЛИТ ИЗ ДРЕВЕСНОГО ВОЛОКНА . использован огнезащитный состав на осноне ортофосфорной кислоты и органических соединений. В этом случае дл получени плит пониженной горючести волокно внутре него сло смешивают с самозатухающйм, пенополистиролом. Сравнительные физико-механические показатели плит: Известных Предлагаем Плотность, кг/мS5O650 Толщина, мм76 Предел прочности при изгибе, кгс/см 145225 Приведенна прочность265345 Набухание за 24 час, % 6,33, Предмет изобретени 1. Способ изготовлени плит из древесного волокна, обработанного реакционно способными соединени ми, например, поли-j функциональным огнезащитным составом на основе ортофосфорной кислоты и огранических оснований, путем послойного воздушного формировани ковра и гор чего прессовани , отличающийс тем, что, с целью обеспечени возможности получени полутвердых плит при сухом и по- луЕухом методах прессовани при пониженных температурах, обработанное волокно внутреннего сло смешивают с подвспененным до насыпной массы 2ОО-550 кг/м гранулированным пенопопистиролом в количестве 10-5О вес. %, а процесс прессовани ведут с ограничительными рамками при 160-175 С. 2. Способ по п. 1,отлича ющ и и с тем, что волокно внутреннего сло смешивают с самозатухающим пено- полистиролом.(54) METHOD OF MANUFACTURING PLATES FROM WOOD FIBER. A flame retardant based on phosphoric acid and organic compounds was used. In this case, in order to obtain low flammability plates, the fiber inside it is mixed with self-extinguishing foam polystyrene. Comparative physicomechanical indicators of plates: Known We offer Density, kg / mS5O650 Thickness, mm76 Flexural strength, kgf / cm 145225 Given strength265345 Swelling in 24 hours,% 6.33, Subject of the Invention 1. Method of manufacturing wood fiber boards, treated reactive compounds, for example, poly-j functional flame retardant based on orthophosphoric acid and organic bases, by layer-by-layer air-forming of a carpet and hot pressing, characterized in that and the possibility of preparing the dry semi-slabs and po- luEuhom compression methods at lower temperatures, the treated fiber is mixed with the inner layer to a bulk weight podvspenennym 2oo-550 kg / m in an amount of granular penopopistirolom 10-5O weight. %, and the pressing process is carried out with restrictive frames at 160-175 C. 2. The method according to claim 1 is also characterized in that the fiber of the inner layer is mixed with self-extinguishing polystyrene foam.
