Cov iav kho qhov muag yog qhov tshwj xeeb ntawm cov khoom siv iav, uas yog ib qho ntawm cov ntaub ntawv tseem ceeb rau kev tsim kho cov cuab yeej tsim. Nws muaj cov khoom kho tshiab thiab tshuaj lom neeg lub cev thiab tshuaj lom neeg, thiab ua lub luag haujlwm tseem ceeb hauv kev siv kho kab mob kho qhov muag.

Dab tsi yog cov khoom siv kho tshiab yog dab tsi?

Cov iav kho qhov muag tuaj yeem muab faib rau ntau hom raws li cov ntawv thov thiab cov yam ntxwv. Ntawm no yog ntau hom ntawm cov iav iav:

1. Lub khob silic

Silic iav yog feem ntau hom kho qhov muag iav, thiab nws lub ntsiab sib xyaw ua si li, feem ntau muaj cov khoom sib tshooj xws li cov roj hauv cov roj coron, sodium oxide, thiab magnesium oxide.

2. Cov iav Lead

Cov iav ua rau pom lub khob kho mob nrog ib qho kev faib tawm ntawm cov txhuas ntxiv, uas muaj cov khoom siv tsis zoo thiab feem ntau siv rau cov twj siv tshuaj thiab tsom iav.

3. Borosilicate iav

Borosilicate iav yog feem ntau yog ntxiv nrog boron oxide, uas muaj qhov kev ua kom siab dua tshiab thiab tsis muaj peev xwm siv nyob rau hauv kev tsim khoom ntawm lo ntsiab muag thiab prisms.

4. Quartz iav

Lub ntsiab tivthaiv ntawm quartz iav kuj tseem sireaton dioxide, uas muaj cov khoom siv tshiab zoo thiab tshuaj ruaj khov, thiab tam sim no dav siv nyob rau hauv cov khoom siv kho thiab cov khoom siv.

5. Tsis muaj lub ntiaj teb iav

Tsis tshua muaj ntiaj teb iav yog lub khob kho qhov muag tau ua los ntawm kev ntxiv cov khoom siv tsis tshua muaj qhov muag ntawm cov khoom lag luam qib siab xws li lasers.

Qhov sib txawv ntawm qhov muag iav thiab iav zoo tib yam

Piv rau cov iav decient, iav kho qhov muag yog qhov ua kom zoo dua thiab cov txheej txheem ua haujlwm, kev ua haujlwm kho kho, thiab lwm yam. Lub ntsiab sib txawv yog:

Thickness thiab hnyav

Qhov chaw kho qhov muag feem ntau muaj qhov tuab me me thiab hnyav dua, ua kom haum rau kev tsim kho cov khoom siv kho kom zoo nkauj. Cov iav zoo tib yam tuaj yeem ua kom tuab thiab hnyav dua vim cov ntawv thov sib txawv.

Ib feem

Qhov muag kho qhov muag yog ntau dawb huv nyob rau hauv muaj pes tsawg leeg nyob rau hauv kev sib xyaw thiab cov khoom siv zoo li qub kom ua tiav cov ntaub ntawv kom ua tiav cov khoom xav tau. Qhov muaj pes tsawg leeg ntawm lub khob zoo tib yam yog qhov yooj yim dua, feem ntau muaj ntawm silicates thiab lwm yam impurities.

Npaj txheej txheem

Kev siv kho qhov muag siv tau yuav tsum muaj cov txheej txheem npaj ua kom zoo, thiab kho cua sov kom ntseeg tau cov kev ruaj khov thiab qhov tseeb ntawm kev ua haujlwm kho qhov muag. Lub khob zoo tib yam uas tau txais kev pab cov iav pib ua cov txheej txheem, thiab tus nqi tsim yog tsawg.

Kev ua kho qhov muag

Cov iav kho qhov muag tau muaj cov yam ntxwv zoo li ntau dua li kev puas tsuaj ntau dua, thiab txo cov kev nqus, thiab nws txoj kev ua haujlwm kho qhov muag tau zoo. Yog li no, kho qhov muag iav tuaj yeem siv tau dav hauv cov cuab yeej kho qhov muag xws li lo ntsiab muag, princs, thiab cov lim dej rau kev kho kho qhov muag.

Txawm li cas los xij, lub khob zoo ib txwm muaj kev ua tau zoo rau kho qhov muag thiab feem ntau siv hauv liaj teb xws li cov khoom ntim thiab cov khoom siv hauv tsev.
