Изобретение относитс к производству строительных материалов, в частности волокнистых плит, с вертикальным направлением волокон.The invention relates to the production of building materials, in particular fiber boards, with the vertical direction of the fibers.
Известен способ изготовлени волокнистых плит с вертикальным направлением волокон, включающий операции термообработки, формировани слоистого крупногабаритного куба, уплотнени и разрезки его поперек доминирующего направлени волокон. Цель изобретени - снижение трудоемкости изготовлени плит и снижение их себестоимости. Достигаетс цель тем, что крупногабаритный куб формуют из свежеотформованных,пропитанных св зующим волокнистых заготовок , после чего его уплотн ют и подвергают термообработке, а затем разрезают.A known method of manufacturing fiber boards with a vertical direction of the fibers, comprising the operations of heat treatment, forming a layered large-sized cube, compaction and cutting it across the dominant direction of the fibers. The purpose of the invention is to reduce the labor intensity of the manufacture of plates and reduce their cost. The goal is achieved in that the large-sized cube is molded from freshly molded, impregnated binder fiber preforms, after which it is compacted and heat-treated, and then cut.
Технологи изготовлени волокнистых плит с вертикальным направлением волокон следующа .The technology for the manufacture of fiber plates with the vertical direction of the fibers is as follows.
Слой или несколько слоев минеральной ваты влажностью 5%, пропитанной св зующим в количестве 4-5%, складывают в пр моугольную форму горизонтальными сло ми,подпрессовывают до заданного объемного веса и размера . В сжатом состо нии через специальное отверстие в дне подаетс гор чий воздух под давлением 0,1 1 ,0 кг/см, который,проход через вату, нагревает св зующее, и волокна склеиваютс .A layer or several layers of mineral wool with a moisture content of 5%, impregnated with a binder in an amount of 4-5%, are folded into a rectangular shape with horizontal layers, which are pressed to a predetermined volume weight and size. In the compressed state, through a special hole in the bottom, hot air is supplied under a pressure of 0.1-1.0 kg / cm, which, through the wool, heats the binder, and the fibers are glued together.
Процесс термообработки длитс 510 мин при )00-250 С. После термообработки куб извлекают из формы и разрезают на плиты поперек сло мThe heat treatment process lasts 510 minutes at) 00-250 C. After heat treatment, the cube is removed from the mold and cut into plates across the layers
уложенных заготовок.stacked blanks.
I ,I,
Предлагаемый способ позвол ет сократить число операций при производстве волокнистых плит и таким образом снизить их себестоимость.The proposed method makes it possible to reduce the number of operations in the production of fiber boards and thus reduce their cost.
