Quartz raj los yog fused silica raj yog iav raj muaj silica nyob rau hauv amorphous (non-crystalline) daim ntawv. Nws txawv ntawm ib txwm iav raj hauv uas tsis muaj lwm cov khoom xyaw, uas feem ntau yog ntxiv rau iav kom txo qhov kub thiab txias. Quartz tube, yog li ntawd, muaj kev ua haujlwm siab thiab melting kub. Optical thiab thermal zog ntawm quartz raj yog superior rau lwm hom iav raj vim nws purity. Rau cov laj thawj no, nws pom kev siv nyob rau hauv cov xwm txheej xws li semiconductor fabrication thiab cov cuab yeej kuaj. Nws muaj kev sib kis tau zoo dua ultraviolet ntau dua li lwm cov iav.
1) High purity: SiO2> 99.99%.
2) Ua haujlwm kub: 1200 ℃; Soften kub: 1650 ℃ .
3) Kev pom zoo thiab tshuaj lom neeg ua haujlwm: acid-ua hauj, alkali tsis kam, thermal stability
4) Kev saib xyuas kev noj qab haus huv thiab kev tiv thaiv ib puag ncig.
5) Tsis muaj cua npuas thiab tsis muaj cua kab.
6) Cov khoom siv hluav taws xob zoo heev.
Peb muab txhua yam quartz raj: Clear quartz raj, Opaque quartz raj, UV thaiv quartz raj, Frosty quartz raj thiab lwm yam.
Yog tias koj xav tau ntau npaum li cas, peb tuaj yeem kho qee qhov tshwj xeeb quartz raj rau koj.
OEM kuj txais.
1. Tsis txhob khiav lag luam hauv qhov kub tshaj quartz siab tshaj plaws ua hauj lwm kub rau lub sij hawm ntev. Txwv tsis pub, cov khoom yuav deform crystallization los yog softening.
2. Ntxuav cov khoom quartz ua ntej kub kub ua haujlwm ib puag ncig.
Ua ntej tsau cov khoom hauv 10% hydrofluoric acid, tom qab ntawd ntxuav nws nrog dej purity siab lossis cawv.
Tus neeg teb xov tooj yuav tsum hnav hnab looj tes nyias, ncaj qha kov nrog quartz iav los ntawm tes yog inhibited.
3. Nws yog qhov tsim nyog kom ncua lub neej ntev thiab thermal tsis kam ntawm cov khoom siv quartz ntawm kev siv tas li nyob rau hauv qhov kub thiab txias. Txwv tsis pub, kev siv ib ntus yuav txo cov khoom lag luam.
4. Sim kom tsis txhob kov cov khoom alkaline (xws li iav dej, asbestos, potassium thiab sodium compounds, thiab lwm yam) thaum siv quartz iav khoom nyob rau hauv qhov kub thiab txias, uas yog ua los ntawm cov khoom siv acid.
Txwv tsis pub cov khoom los tiv thaiv crystalline cov khoom yuav raug txo kom tsawg.
