Description

устранени лынкости и сплетают из них циновку , кра которой закрепл ют в нагретой займе под давлением 1-5 кг/см при 90 до 150°С. На смазанный металлический поддон укладывают слой опилок толилииой 6-10 мм, пропитанных раствором св зующего, содержащим , Бес.%:: мочевииы - 41-50, формалина - 48-57, красител кубозол - 0,1-0,5, едкого натра - 0,5-0,9. Затем укладывают циновку , насыпают массу из пропаренных опплок с размером частиц 0,3-3 мм и крошкп щпона размером частиц 3-15 мм, перемешанных с мочевпно-формальдегпдпой смолой толщиной 8-40 мм, укладывают вторую циновку, покрывают слоем опплок по толщине, обработанных аналогично нижнему слою, пакет накрывают металлической смазанпой прокладкой п П1)ессуют в гор чем прессе при 140- 170°С од давлением 12-18 кг/см в течение 0,8-1 мин на 1 мм толщины плиты. Полученные нлнты укладывают на вагонетку, накрыBajOT теплозащитным чехлом и охлаждают н течение 20-30 ч.elimination of baldness and weave from them a mat, the edges of which are fixed in a heated loan under a pressure of 1-5 kg / cm at 90 to 150 ° C. A layer of sawdust of 6-10 mm thick Tolilia impregnated with a binder solution containing,%: urea, 41-50, formalin, 48-57, dye cubozeol, 0.1-0.5, caustic soda is placed on a greased metal pallet - 0.5-0.9. Then a mat is laid, a mass of steamed opplocks with a particle size of 0.3-3 mm and crumb of a particle size of 3-15 mm, mixed with urinary-formaldehyde resin with a thickness of 8-40 mm are poured, the second mat is laid, covered with a layer of opplocks in thickness, Processed similarly to the lower layer, the bag is covered with a metal grease pad (P1) and heated in a hot press at 140-170 ° C at a pressure of 12-18 kg / cm for 0.8-1 min per 1 mm of plate thickness. The resulting sheets are placed on a trolley, covered with a Bayot heat shield and cooled for 20-30 hours.

Claims

1. A method of manufacturing an interlayer reinforced slab from wood waste by means of sizing, laying layers on a pallet with the use of the primer as a reinforcing layer of spon-ripped, covering the dialed

package with gasket and nassovanp, characterized in that, in order to obtain form-resistant plates with a water-resistant, non-coping decorative surface, the bottom layer 5 of the ilpty (made 6-O.uu pz opplock, impregnated with a binder solution, containing weight%: urea -41 51, formalia - 48-58, dye kubozol - 0.1-0.5, caustic iatra - 0.5-0.9, then the reinforcing layer is laid in the form of mats made of torn veneer, filled with nz of steamed sawdust with particle size 0.3-3 mm p crochet veneer with dimensions of 3-15 mm, mixed with urea-formaldehyde C1m .toy,

5, a second mat is placed and a layer of sawdust is poured, processed similarly to the lower layer, and the packs are pressed to make 140-170 ° C, specific pressure is 12-18 kg / cm with an exposure time of 0.8-1.0 minutes

0 pas 1 mm tolndips of nlpta, the obtained plates are covered with a heat zolocation cover, but they are cooled for 20-30 h,

2. A method according to claim 1, characterized in that shpon-ravaipyu for glue-stitched mat is cut along the fiber into strips, put them into a ribbon, which is paved with strips of a given size, irocleate, dried-searched at 50-70 ° C and intertwined the edge being fixed under pressure 1-5 at 90
