Fused Quartz Capillary Tubes

Lus piav qhia luv luv:

Fused quartz capillary raj yog precision-engineered microtubes ua los ntawm high-purity amorphous silica (SiO₂). Cov raj no muaj nuj nqis rau lawv cov tshuaj tiv thaiv zoo heev, tshwj xeeb thermal stability, thiab zoo tshaj qhov muag pom tseeb thoob plaws qhov dav ntawm wavelengths. Nrog rau txoj kab uas hla ntawm ob peb microns mus rau ob peb millimeters, fused quartz capillaries tau siv dav hauv kev ntsuas ntsuas, kev tsim khoom semiconductor, kuaj mob, thiab microfluidic systems.

Txheej txheem cej luam ntawm Quartz Capillary Tubes

Tsis zoo li cov iav zoo tib yam, fused quartz muaj ultra-low thermal expansion thiab high-temperature endurance, ua rau nws haum rau hnyav ib puag ncig, lub tshuab nqus tsev vacuum, thiab daim ntawv thov uas muaj kev kub ceev cycling. Cov hlab no tuav qhov kev ncaj ncees thiab tshuaj purity txawm nyob rau hauv huab cua kub, txhua yam, los yog tshuaj lom neeg kev nyuaj siab, ua kom meej thiab rov ua tau zoo nyob rau hauv kev lag luam.

Manufacturing txheej txheem ntawm quartz iav ntawv

Kev tsim cov fused quartz capillary hlab yuav tsum tau ua cov txheej txheem precision fabrication thiab high-purity cov ntaub ntawv. General manufacturing workflow muaj xws li:
1. Kev npaj raw khoom
  High-purity quartz (feem ntau JGS1, JGS2, JGS3, los yog hluavtaws fused silica) raug xaiv raws li daim ntawv thov xav tau. Cov ntaub ntawv no muaj ntau dua 99.99% SiO₂ thiab tsis muaj paug xws li alkali hlau thiab hlau hnyav.
2. Melting thiab kos duab
  Quartz rods los yog ingots yog rhuab nyob rau hauv ib tug cleanroom ib puag ncig mus rau ntau tshaj 1700 ° C thiab kos rau hauv nyias hlab siv micro-drawing tshuab. Tag nrho cov txheej txheem yog ua nyob rau hauv cov huab cua tswj kom tsis txhob muaj kab mob.
3. Dimensional Tswj
  Laser-raws li thiab lub zeem muag-pab tawm tswv yim systems kom meej meej tswj ntawm sab hauv thiab sab diameters, feem ntau nrog kam rau ua nruj li ± 0.005 hli. Phab ntsa thickness uniformity kuj optimized thaum lub sij hawm no.
4. Annealing
  Tom qab kev tsim, cov hlab ntsha tau muab tshem tawm kom tshem tawm cov kev ntxhov siab hauv thermal thiab txhim kho lub sijhawm ntev thiab lub zog txhua yam.
5. Tiav thiab Customization
  Cov raj tuaj yeem yog nplaim-polished, beveled, kaw, txiav kom ntev, lossis ntxuav nyob ntawm cov neeg siv khoom tshwj xeeb. Precision kawg tiav yog qhov tseem ceeb rau cov dej dynamics, optical coupling, los yog kev kho mob-qib daim ntawv thov.
