Fiber ntau cov neeg ua haujlwm hluav taws xob ua tau li cas?
Kev tsim tawm ntawm cov khoom siv kho qhov muag fiber ntau yog muab faib ua peb txheej txheem, namely duab kho qhov muag fiber ntau, kuaj thiab npaj ua ntej.
Npaj ua ntej:
Muaj ntau cov txheej txheem thev naus laus zis rau preform ntau lawm, feem ntau suav nrog MCVD, OVD, VAD thiab PCVD, cov uas siv feem ntau yog txheej txheem MCVD, uas tseem yog tsom ntawm cov kab lus no. Lub npe tag nrho ntawm MCVD hauv Lus Askiv yog hloov kho cov tshuaj vapor deposition. Cov txheej txheem tsim hluavtaws fiber ntau no tau tsim los ntawm Tswb Labs xyoo 1974. Cov roj cua sib xyaw ua ke yog SiCl4 (silicon chloride), GeCl4 (germanium chloride) thiab lwm yam tshuaj lom neeg yog nkag tau rau hauv quartz iav raj (cladding), thiab quartz raj yog tig thiab rhaub, thiab cov silicon thiab germanium yog oxidized los ua SiO2 (Silica) thiab GeO2 (germanium dioxide) ua kom nws nyob hauv lub raj quartz los ua qhov tseem ceeb ntawm qhov kho qhov muag.
Tsis tas li ntawd, tsis xws li qhov ntsuas tsis pom zoo, nthuav tawm qhov sib npaug, thiab qhov chaw sib ntawm qhov kho qhov muag kuj tseem tuaj yeem tswj tau los ntawm cov khoom sib xyaw ua ke ntawm cov roj tov sib xyaw. Tom qab cov qauv ua ntej nyob hauv lub xeev txias, nws qhov zoo yuav tsum tau soj ntsuam.
Yog nqus tau fiber ntau:
Tso cov preform rau hauv fiber ntau ntawm kev teeb tsa ntauwd rau kev kos duab. Qhov preform tom qab kos duab yuav dhau los ua 125μm tuab thiab nyias fiber ntau kho qhov muag, thiab yog coated nrog ob txheej txheej los tiv thaiv lub zog ntawm cov fiber ntau kho qhov muag. Tus qauv ntawm cov fiber ntau txoj kev teeb tsa ntau yam suav nrog graphite lub tshuab ua kom sov, tuaj yeem ua qhov kub siab ntawm 1700-2000 degrees, ua kom zoo siab muag ntawm preform, thiab cua nws los ntawm kev kos duab lub log kom ua rau muaj ntau qhov sib luag optical fiber ntau.
Cov duab kos ntau tuaj yeem pub rov qab rau hauv qhov cub tawg thiab cua nrawm, thiab tswj cov duab fiber ntau los ntawm lub laser micrometer. Txhawm rau txhawm rau txhim kho lub zog ntawm cov roj carbon fiber ntau, txheej txheem kev kos duab yuav tsum tau txheej lub fiber ntau nrog txheej txheej tuab ntawm lub sij hawm thiab qhuav nws kom tsis txhob muaj kev sib txuam.
Ntsuas:
Tom qab kos duab, nws yog qhov yuav tsum tau soj ntsuam cov fiber ntau tiav. Kev ntsuas qhov tsis suav nrog lub zog tensile, ntsuas qhov ntsuas xyuas, fiber qauv, saib kom pom, cov ntaub ntawv nqa lub peev xwm (bandwidth), kev faib tawm, kev khiav hauj lwm kub thiab av noo ntau, thiab lwm yam
