Kev Tshawb Fawb Txog Cov Yam Tseem Ceeb Uas Cuam Tshuam Rau Qhov Zoo ntawm Cov Khoom Siv Quartz Fiber

Quartz fiber, nrog nws cov purity siab, kub tsis kam, ablation tsis kam, thermal conductivity qis, thermal shock tsis kam, nthwv dej kis tau zoo, dielectric zoo heev, thiab tshuaj lom neeg ruaj khov zoo, ua lub luag haujlwm tseem ceeb hauv kev tsim khoom siab xws li aerospace, kev sib txuas lus hauv hluav taws xob, thiab optics. Txawm li cas los xij, cov txheej txheem npaj, los ntawm cov khoom siv quartz ntuj siab mus rau kev ua tau zoo siabcov khoom siv fiber quartz, yog ib qho kev ua haujlwm uas nyuaj heev thiab raug cuam tshuam los ntawm ntau yam.

1. Cov Khoom Siv Raw

Qhov kev tsom mus rau cov khoom siv raw feem ntau suav nrog kev huv, qhov loj me ntawm cov khoom me me, thiab cov pa roj. Hais txog kev huv, cov hlau tsis huv yog ib qho tseem ceeb uas cuam tshuam. Txawm tias alkali hlau, alkaline ntiaj teb hlau, lossis cov hlau hloov pauv ions uas muaj nyob rau hauv cov concentration ntawm tsuas yog ob peb feem ib lab tuaj yeem muaj kev cuam tshuam loj rau cov khoom siv quartz fiber: txo qhov kub thiab txias, ua rau lawv yooj yim deformation thiab tsis ua haujlwm ntawm qhov kub siab; inducing crystallization, ua kom nrawm hloov pauv ntawm quartz iav los ntawm lub xeev amorphous mus rau lub xeev cristobalite crystalline ntawm qhov kub siab, ua rau fiber brittleness thiab txo qis zog; thiab cuam tshuam rau cov khoom dielectric, raws li impurity ions ua rau dielectric poob, cuam tshuam nws daim ntawv thov hauv cov khoom siv hluav taws xob siab.

Qhov loj me ntawm cov khoom me me thiab cov pa roj ntawm cov khoom siv raw txiav txim siab cov npuas ntawm cov pas nrig quartz tsim tawm. Cov pas nrig iav quartz nrog cov npuas siab feem ntau yuav tawg thaum lub sijhawm yaj thiab ua rau muaj kev nce ntxiv ntawm cov qhov tsis zoo ntawm cov nplaim quartz fiber, uas qee qhov cuam tshuam rau qhov zoo thiab kev ua tau zoo ntawm cov khoom tiav quartz fiber.

2. Kev Kos Duab Yaj

Kev hloov cov khoom siv quartz khov kho mus rau hauv cov fibers txuas ntxiv thiab sib xws yog ib kauj ruam tseem ceeb hauv kev txiav txim siab nws cov microstructure thiab cov khoom siv kho tshuab. Siv cov duab kos ntawm cov pas nrig quartz siv cov nplaim oxyhydrogen ua piv txwv, qhov huv si, siab, thiab ntws ntawm hydrogen thiab oxygen, kev tswj kub thiab kev hloov kho, txoj kev kos duab, thiab cov khoom siv yog txhua yam txiav txim siab ncaj qha ntawm cov khoom siv quartz fiber zoo.

Qhov kub yaj feem ntau yog tswj los ntawm qhov ntws thiab siab ntawm cov pa roj combustion. Yog tias qhov kub yaj siab dhau, cov fibers yuav yaj thiab tawg; yog tias qhov kub qis dhau, qhov kev nruj ntawm kev tsim khoom nce ntxiv, ua rau fraying thiab tawg ntau dua. Ntxiv mus, kev huv si ib puag ncig kuj tseem ceeb heev, vim tias tag nrho cov txheej txheem kos duab yuav tsum tau ua nyob rau hauv ib puag ncig huv si. Txhua yam hmoov av hauv huab cua uas lo rau ntawm qhov chaw fiber yuav dhau los ua cov ntsiab lus ntxhov siab, txo nws lub zog kho tshuab.

3. Cov qauv me me

Kev ruaj khov ntawmcov fibers quartznyob rau hauv lub sijhawm ntev kub siab nyob ntawm lawv qhov kev tiv thaiv rau crystallization. Raws li tau hais ua ntej, crystallization yog lub hauv paus tseem ceeb ntawm cov quartz fibers ntawm qhov kub siab. Tus nqi crystallization muaj kev sib raug zoo exponential nrog kub. Cov yam tseem ceeb uas cuam tshuam rau crystallization suav nrog:
* Qhov chaw nto: Cov kab nrib pleb me me, kev ua qias tuaj, thiab kev hnav ntawm qhov chaw fiber tuaj yeem ua rau muaj kev siv lead ua. Yog li ntawd, kev kho qhov chaw thiab kev tiv thaiv txheej txheem yog qhov tseem ceeb.
* Cov qhov me me: Rau cov ntaub ntawv tawg yooj yim xws li cov fibers quartz, lawv lub zog yog qhov rhiab heev rau cov qhov tsis zoo xws li qhov chaw thiab sab hauv microcracks, npuas, thiab cov khoom suav nrog. Cov txheej txheem tom qab kho xws li nplaim taws polishing thiab acid pickling tuaj yeem kho tau zoo microcracks ntawm qhov chaw thiab txhim kho lub zog.

4. Tus Neeg Sawv Cev Loj

Thaum lub sijhawm ua cov txheej txheem kos duab quartz fiber, yuav tsum muaj ib tus neeg sawv cev kho qhov chaw tshwj xeeb uas tau pleev xim rau ntawm qhov chaw fiber. Qhov no ua kom lubricates qhov chaw fiber zoo, ua kom cov fiber monofilaments sib xyaw ua ke zoo rau hauv ib lub pob, thiab hloov pauv qhov xwm txheej ntawm qhov chaw fiber. Qhov no tsis yog tsuas yog ua tau raws li qhov yuav tsum tau ua ntawm kev ua cov txheej txheem fiber tom qab xwb tab sis kuj txhawb nqa kev sib txuas ntawm cov fiber quartz thiab cov polymer reinforced hauv cov ntaub ntawv sib xyaw.

Qhov zoo ntawmcov khoom siv fiber quartztsis yog txiav txim siab los ntawm ib kauj ruam xwb, tab sis los ntawm cov txheej txheem engineering meej uas cuam tshuam nrog tag nrho cov saw hlau ntawm cov khoom siv raw purity, cov txheej txheem kos duab yaj, kev tswj hwm microstructure thiab cov thev naus laus zis tom qab ua tiav.
