Description
Во врем работы устройства потоки 4 расплава полимера выход т из фильеры ир дильного блока и эжектируютс в сопло 8 за счет вакуума, создаваемого потоком сжатого газа, выход щего с большой скоростью из зазора, и поступают в диффузор 11, где происходит основиа выт жка потока расплава в волокна 13.During operation of the device, the polymer melt flows 4 exit the spinning nozzle of the irradiation unit and are ejected into the nozzle 8 due to the vacuum created by the stream of compressed gas exiting the gap at high speed and enter the diffuser 11, where the melt flow is formed. into fibers 13.
Направители 9 передвигают и фиксируют так, что отдельные струи потока расплава отт гиваютс от центра и попадают в потоки воздуха в сопле и диффузоре, движущиес с более высокой скоростью. При этом диаметр факела волокон в сопле увеличиваетс , шаг между стру ми расплава становитс больше, что улучшает качество получаемого материала.The guides 9 are moved and fixed so that the individual jets of the melt flow are pulled away from the center and fall into the air flow in the nozzle and the diffuser, moving at a higher speed. As the diameter of the fiber plume in the nozzle increases, the spacing between the melt streams becomes larger, which improves the quality of the material produced.
Более точное регулирование сло газа в диффузоре с целью создани оптимальных условий дл исключени возможности сли ни струи расплава поворачивают плавно дополнительный диффузор 12 относительно диффузора И. При этом долевые прорези диффузора И постепенно перекрываютс , в результате чего измен етс количество воздуха, всасываемого из окружающего пространства (стрелки Г).A more precise control of the gas layer in the diffuser in order to create optimal conditions to prevent the melt jet from merging smoothly rotates the additional diffuser 12 relative to the diffuser I. At the same time, the fractional slots of the diffuser And gradually overlap, resulting in a change in the amount of air drawn in from the surrounding space arrows D).
Волокна 13 поступают в приемное устройство 14. The fibers 13 enter the receiving device 14.
