Description
Известен способ изготовлени оптического стекловолокна, состонидего из световедущей сердцевины и светоизолирующей оболочки путем нагревани до температуры разм гчени и одповремениого выт гивани стекл нной трубки с влол ениым в нее с зазором стекл нным штабиком. Такой способ не обеспечивает плотного прилегани сердцевины к оболочке.A known method of manufacturing optical glass fiber, consisting of a light-guiding core and a light-insulating shell by heating to a softening temperature and simultaneously drawing a glass tube with a glass staff that has a gap in it with a gap. This method does not ensure a tight fit of the core to the shell.
Предлагаемый способ позвол ет устранить этот недостаток. Достигаетс это тем, что в процессе выт гивани стекл нной трубки вместе со штабиком из кольцевой полости между ними откачивают воздух.The proposed method eliminates this disadvantage. This is achieved by the fact that in the process of drawing out the glass tube together with the staff, air is pumped out of the annular cavity between them.
На чертеже показано устройство дл осуществлени способа.The drawing shows a device for carrying out the method.
Стекл нную трубку / с помещенным в нее с зазором до 5 мм и более стекл нным штабиком 2 закрепл ют в подающем механизме 3. Один конец трубки запа н, а другой резиновым шлангом 4 св зан с вакуумным насосом 5.A glass tube / with a glass core 2 placed therein with a gap of more than 5 mm and more is fixed in the feed mechanism 3. One end of the tube is sealed and the other with rubber hose 4 connected to a vacuum pump 5.
Трубку со штабиком непрерывно подают в нагревательную трубчатую печь 6 и одновременно из кольцевого зазора между ними откачивают воздух. Конец трубки со штабиком.The tube with staff is continuously fed into the heating tube furnace 6 and at the same time air is pumped out from the annular gap between them. The end of the tube with staff.
помещенный в нагревательную печь, под действием температуры разм гчаетс и вследствие разр жени разм гченное стекло трубки плотно сплавл етс с разм гченным стеклом штабика. Одновременно из сплавленных таким образом трубки и штабика выт гивают оптическое волокно, поддержпва на прот жении всего процесса выт жки необходимое разр л ение .placed in a heating furnace, under the action of temperature, softens and, due to discharge, the softened glass of the tube fuses tightly with the softened glass of the core. At the same time, the optical fiber is pulled out of the tubes fused in this way and supported by the fiber, while maintaining the necessary discharge during the entire stretching process.
Полученное стекловолокно имеет высокую прочность и хорошие светопровод щие свойства .The glass fiber obtained has high strength and good light-conducting properties.
