Txheej txheem cej luam ntawm Quartz iav

Peb cov ntawv quartz iav yog tsim los siv cov khoom siv qib siab tshaj plaws xws li ntuj siv lead ua lossis hluavtaws silica, ua tiav los ntawm cov txheej txheem melting thiab polishing. Qhov tshwm sim yog lub tiaj tus, tsis tshua muaj impurity, thiab npuas-dawb nto uas ua tau raws li cov kev cai nruj tshaj plaws ntawm cov txheej txheem kev lag luam niaj hnub no.

Cov yam ntxwv tseem ceeb ntawm Quartz iav Sheets

Kev Thermal Resistance heev
Quartz iav ntawv tuaj yeem tiv taus qhov kub txog li 1100 ° C hauv kev siv tas li thiab txawm tias siab dua nyob rau hauv luv luv tawg. Lawv tsis tshua muaj coefficient ntawm thermal expansion (~ 5.5 × 10⁻⁷ / ° C) kom ntseeg tau zoo thermal shock kuj.
High Optical Transparency
Lawv muab cov pob tshab zoo heev hauv UV, pom, thiab IR spectrum nyob ntawm qib, nrog rau kev sib kis ntau tshaj 90% hauv ntau qhov pom. Qhov no ua rau lawv zoo tagnrho rau kev siv photolithography thiab laser.
Chemical Durability
Quartz iav yog inert rau feem ntau acids, bases, thiab corrosive gases. Qhov kev tiv thaiv no yog qhov tseem ceeb rau cov chaw huv huv thiab kev ua cov tshuaj purity siab.
Mechanical Strength thiab Hardness
Nrog rau Mohs hardness ntawm 6.5-7, quartz iav los xij muab kev khawb zoo thiab kev ncaj ncees, txawm tias nyob rau hauv kev xav tau.
Hluav taws xob rwb thaiv tsev
Quartz yog ib qho zoo heev hluav taws xob insulator thiab yog dav siv nyob rau hauv high-frequency thiab high-voltage daim ntaub ntawv vim nws tsis tshua muaj dielectric tsis tu ncua thiab siab resistivity.

FAQ ntawm Quartz Glasses

Q1: Dab tsi yog qhov txawv ntawm fused quartz thiab fused silica?
A:Fused quartz yog tsim los ntawm ntuj quartz siv lead ua melted ntawm qhov kub thiab txias, thaum fused silica yog tsim los ntawm high-purity silicon tebchaw los ntawm cov tshuaj vapor deposition los yog hydrolysis. Fused silica feem ntau muaj ntau dua purity, zoo dua UV kis tau tus mob, thiab cov ntsiab lus impurity qis dua fused quartz.

Q2: Cov quartz iav tuaj yeem tiv taus qhov kub thiab txias?
A:Yog lawm. Quartz iav los xij muaj kev ruaj ntseg zoo heev thiab tuaj yeem ua haujlwm tsis tu ncua ntawm qhov kub txog li 1100 ° C, nrog rau lub sij hawm luv luv mus txog 1300 ° C. Lawv kuj muaj thermal expansion tsis tshua muaj, ua rau lawv tiv taus thermal shock.

Q3: Puas yog quartz iav los xij resistant rau tshuaj?
A:Quartz tiv taus ntau cov kua qaub, suav nrog hydrochloric, nitric, thiab sulfuric acids, nrog rau cov kuab tshuaj organic. Txawm li cas los xij, nws tuaj yeem raug tawm tsam los ntawm hydrofluoric acid thiab muaj zog alkaline daws zoo li sodium hydroxide.

Q4: Kuv puas tuaj yeem txiav lossis laum quartz iav nplooj ntawv kuv tus kheej?
A:Peb tsis pom zoo DIY machining. Quartz yog nkig thiab tawv, xav tau cov cuab yeej pob zeb diamond thiab cov cuab yeej CNC lossis laser rau kev txiav lossis drilling. Kev tuav tsis raug tuaj yeem ua rau tawg lossis tawg ntawm qhov chaw.
