Description
Сформированную нить выт гивают с помощью эжектора и укладывают в приемное устройство Лучший режим формовани (пример 3) позвол ет в этих услови х получить волокно диаметром 32 мкм. Из этого волокна путем термообработки не удаетс получить углеродное волокно с высокими показател ми, его прочность составл ет 31 кг/мм , что объ сн етс большим диаметром свежесформированного и, соответственно , углеродного волокнаThe formed thread is drawn using an ejector and placed in a receiving device. The best spinning mode (Example 3) allows one to obtain a fiber with a diameter of 32 microns under these conditions. It is not possible to obtain high-performance carbon fiber from this fiber by heat treatment, its strength is 31 kg / mm, which is explained by the large diameter of the freshly formed and, accordingly, carbon fiber
Стабильность процесса формовани также невысока: через 30 минут наблюдает- ст засор отверстий фипьерыThe stability of the molding process is also low: after 30 minutes, there is a clogging of the openings of the fixture
Увеличение диаметра отверсти фильеры дл снижени опасности засора невозможно , так как при этом дополнительно возрастает диаметр сформованного волок0It is not possible to increase the diameter of the die hole to reduce the risk of clogging, since this also increases the diameter of the formed fiber
Увеличение подачи во эдуха в )рктор с целью повышени ступени вытчгипани и снижени Диаметра волокна приводит к рез кому возрастанию его обрывности При повышении температуры формование с 260 до 280°С (пример 4) плов пека тер ет спо собность к волокнообразооанию, что обьчс н етс (как это отмечено в описании зачвки) сильным снижением в зкости расплава п каIncreasing the supply to edu c) the reactor in order to increase the degree of extrusion and reduce the Diameter of the fiber leads to a sharp increase in its breakage. At an increase in temperature, molding from 260 to 280 ° C (Example 4), the baked cake loses its ability to fiber formation, which is usually the case. (as noted in the description of the dressing) a strong decrease in the viscosity of the melt
