원심력을 이용한 광통신용 광섬유 모재제조 : 미세입자 크기 및 이동식 injection tube의 영향

In this paper, the technique to fabricate the optical fiber preforms by centrifuge was investigated, using silica particles of different sizes. The injection tube was designed to traverse axially so that uniform coating of tiny silica particles onto the substrate tube can be certified. The deposition efficiencies and deposition rates of SiO2 Particles were measured to elucidate the effects of process variables such as rotation speed of rotor, aqueous flow rate, suspension concentration, binder concentration and overflow weir diameter. This study shows clearly the merit of this technique by enhancing abruptly the deposition rates and deposition efficiencies, comparing to the conventional processes for optical fiber preforms.

The activation carbon has mostly high surface areas over 1000㎡/g but has prepared by expensive process. So the study on using with activation carbon is very active. We prepared glassfiber reinforced activation carbon fabric with using glassfiber and novolac phenolic resin and activated CO₂, NH₃, N₂ gas. Besides we adsorbed SO_X with activated samples and measured surface areas by a method of BET.
