Thaum hnav tsom iav, koj xaiv hom dab tsi? Puas yog nws lub ntsej muag zoo nkauj zoo nkauj kub? Los yog cov ncej loj uas ua rau koj lub ntsej muag me dua? Txawm koj nyiam qhov twg, qhov kev xaiv ntawm cov ncej yog qhov tseem ceeb heev. Hnub no, cia peb tham txog me ntsis kev paub txog thav duab.
Thaum xaiv ib lub thav duab, koj yuav tsum xub xav txog qhov ua tau zoo thiab kev nplij siab, thiab thib ob xaiv los ntawm kev zoo nkauj.
◀ Cov khoom siv ▶
Tam sim no, cov ntaub ntawv tseem ceeb hauv kev ua lag luam yog: ntshiab titanium, beta titanium, alloy, phaj, thiab TR.
01-Titanium
Titaniumcov khoom uas muaj purity ntau tshaj 99% yog ultra-light thiab feem ntau yog cim nrog 100% TITANIUM ntawm lub tuam tsev lossis lo ntsiab muag.
Qhov zoo: Ntshiab titanium iav tsom iav yog lub teeb thiab xis nyob. Cov khoom siv yog lub teeb tshaj plaws ntawm cov khoom siv tsom iav thiab muaj hardness zoo heev. Cov thav duab tsis yooj yim deformed, yog corrosion-resistant, tsis xeb, tsis ua rau daim tawv nqaij ua xua, thiab kuj tseem ruaj.
Qhov tsis zoo: Cov txheej txheem casting yog qhov xav tau ntau dua thiab tus nqi kuj tseem siab.
02-B titanium ncej
Lwm daim ntawv molecular ntawm titanium, nws muaj ultra-light thiab super-elastic zog thiab feem ntau yog siv los ua cov tuam tsev. Feem ntau txheeb xyuas los ntawm Beta Titanium lossis βTitanium.
Qhov zoo: zoo weldability, forgeability, plasticity thiab processability. Zoo yooj, tsis yooj yim rau deform, lub teeb yuag.
Disadvantages: Tsis haum rau cov neeg siab dua. Sab pem hauv ntej ntawm tus ncej yog hnyav heev thiab yooj yim rau swb. Cov lo ntsiab muag yog tuab heev thiab cuam tshuam rau qhov tsos thiab tsis tuaj yeem hloov kho. Muaj ntau ntau cov khoom siv β-titanium nyob rau hauv kev ua lag luam, thiab lawv qhov zoo sib txawv, yog li lawv tsis haum rau qee cov neeg uas muaj kev tsis haum hlau.
03-Alloy
Muaj plaub pawg loj: tooj liab alloys, nickel alloys, titanium alloys thiab precious hlau. Cov ntaub ntawv alloy muaj qhov sib txawv me ntsis hauv lub zog, kev tiv thaiv corrosion, thiab lub cev thiab tshuaj lom neeg.
Qhov zoo: Ua los ntawm kev sib xyaw ntawm cov khoom sib txawv ntawm cov hlau los yog cov hlau alloy, lawv muaj kev ruaj khov dua li cov iav ua los ntawm cov khoom siv niaj hnub thiab tuaj yeem tiv taus kev sib txhuam thiab kev sib tsoo los ntawm kev siv txhua hnub. Ntxiv mus, tus nqi kuj nyob ze rau cov neeg, cov xim yog ci, kev ua haujlwm nyuaj yog tsawg, thiab nws yooj yim los kho.
Disadvantages: Nws tsis tuaj yeem tiv taus corrosion nyob rau hauv qhov kub thiab txias ib puag ncig, qee cov neeg tuaj yeem ua rau cov hlau tsis haum, muaj kev cuam tshuam rau extrusion thiab deformation, thiab hnyav.
04-Acetate
Ua los ntawm high-tech yas nco Acetate, feem ntau ntawm cov khoom xyaw Acetate tam sim no yog acetate fiber, thiab ob peb lub siab kawg yog ua los ntawm propionate fiber.
Qhov zoo: siab hardness, sov kev ntxhib los mos, muaj zog hnav tsis kam, tiv thaiv kev ua xua thiab hws-pov thawj, haum rau txhua hom tawv nqaij, tshwj xeeb tshaj yog rau cov neeg muaj hlau tsis haum.
Disadvantages: Cov khoom yog ib qho nyuaj thiab nyuaj rau kho. Lub thav duab yog hnyav thiab nyiam xoob thiab xaub hauv huab cua kub, thiab cov ntaub qhwv lub qhov ntswg tsis tuaj yeem hloov kho.
05 - TR
Composite super-elastic resin khoom tsim los ntawm Koreans thiab siv rau kev tsim tsom iav.
Qhov zoo: zoo yoog raws, siab tsis kam, tus nqi pheej yig, khoom siv ultra-teeb. Nws yog lub teeb nyob rau hauv qhov hnyav, ib nrab ntawm qhov hnyav ntawm lub phaj, uas tuaj yeem txo lub nra ntawm tus choj ntawm lub qhov ntswg thiab pob ntseg, thiab sib npaug sib npaug rau lub sijhawm ntev. Cov xim ntawm lub thav duab yog qhov zoo tshaj plaws, thiab kev hloov pauv tau zoo heev. Qhov zoo elasticity tuaj yeem tiv thaiv kev puas tsuaj rau lub qhov muag los ntawm kev cuam tshuam thaum kis las. Nws tuaj yeem tiv taus qhov kub ntawm 350 degrees hauv lub sijhawm luv luv, tsis yooj yim rau yaj thiab hlawv, thiab cov ncej tsis yooj yim rau deform lossis hloov xim.
Disadvantages: Tsis zoo stability. Piv nrog cov tsom iav hlau hlau, qhov uas kho cov lo ntsiab muag tsis tshua ruaj khov, thiab cov lo ntsiab muag yuav xoob. Nws yog ib qho nyuaj rau hloov mus rau txhua lub ntsej muag, yog li qee tus neeg yuav tsum xaiv cov style uas haum rau lawv. Cov tshuaj tsuag pleev xim rau saum npoo kev kho mob tsis yog ib puag ncig zoo, thiab cov xim txheej nrog cov tshuaj tsuag tsis zoo yuav tev tawm sai sai.
◀ Ncej loj ▶
Qhov loj ntawm lub thav duab yuav tsum tsim nyog kom qhov chaw ntawm lub qhov muag dub (cov tub ntxhais kawm cheeb tsam) nyob rau hauv nruab nrab ntawm lub lens, tsis yog sab hauv. Cov thav duab yuav tsum tau xis nyob thaum muab tso rau, tsis txhob nias tawm tsam koj pob ntseg, qhov ntswg lossis lub tuam tsev, lossis xoob dhau.
Lub tswv yim: Lub ntsej muag lub ntsej muag yuav tsum phim qhov tsim ntawm lub lens.
Nyob rau hauv cov ntaub ntawv ntawm lub zog siab, qhov luaj li cas ntawm tus ncej yog qhov zoo tshaj plaws matched rau lub interpupillary nrug kom txo tau cov ntug thickness. Kev ntsuas qhov sib nrug deb yog los xyuas kom meej tias lub qhov muag pom cov khoom los ntawm qhov chaw kho qhov muag ntawm lub lens. Txwv tsis pub, cov nyhuv "prism" tuaj yeem tshwm sim tau yooj yim. Hauv qhov xwm txheej hnyav, daim duab ntawm retina tuaj yeem raug deflected, ua rau pom qhov muag tsis pom.
◀ Nose pad style ▶
Kho qhov ntswg pads
Qhov zoo: Feem ntau siv rau ntawm cov phaj thav duab, lub qhov ntswg thiab cov thav duab sib xyaw ua ke, ua kom yooj yim txij nkawm. Tsis zoo li lub qhov ntswg txav tau, uas yuav tsum tau nruj nruj ntawm cov ntsia hlau, lawv tsis yooj yim rau ntxiab av thiab kev phem.
Qhov tsis zoo: Lub qhov ntswg qhov ntswg tsis tuaj yeem hloov kho thiab tsis tuaj yeem haum tus choj ntawm lub qhov ntswg zoo.
Independent qhov ntswg pads
Qhov zoo: Qhov zoo ntawm lub qhov ntswg qhov ntswg tuaj yeem hloov kho raws li cov duab ntawm tus choj ntawm lub qhov ntswg, kom ntseeg tau tias lub siab ntawm tus choj ntawm lub qhov ntswg sib npaug thiab txo qis hauv zos.
Disadvantages: Lub nruj ntawm cov ntsia hlau yuav tsum tau xyuas ntau zaus thiab cov ntsia hlau yuav tsum tau txhuam thiab ntxuav tsis tu ncua. Qhov ntswg pads feem ntau yog ua los ntawm cov khoom siv silicone. Lawv zoo li tig daj tom qab siv tau ntev, cuam tshuam rau lawv cov tsos thiab yuav tsum tau hloov.
◀ Ncej hom ▶
puv rims
Qhov zoo: Muaj zog, yooj yim rau cov duab, tuaj yeem npog ib feem ntawm lub lens ntug thickness.
Qhov tsis zoo: Cov ncej puv nrog cov iav me me muaj qee yam cuam tshuam rau peripheral tsis pom kev.
ib nrab rim ncej
Qhov zoo: Qhov chaw saib hauv qab no yog dav dua li ntawm tag nrho cov ncej. Txo cov khoom siv hauv cov ncej tuaj yeem txo qhov hnyav ntawm cov iav, ua rau lawv sib zog.
Qhov tsis zoo: Vim tias qhov qis qis tsis muaj kev tiv thaiv los ntawm tus ncej, nws yooj yim dua rau kev puas tsuaj.
rimless ncej
Qhov zoo: sib dua thiab dav ntawm qhov pom kev.
Disadvantages: Txij li thaum kev sib txuas ntawm tus ncej thiab lub lens yog tag nrho tsau los ntawm screws, tsis muaj thav duab tiv thaiv, nws yog ib qho yooj yim rau deform thiab puas, thiab qhov yuav tsum tau rau lub lens yog siab dua.
Rau fittings nrog cov tshuaj loj dua thiab cov lo ntsiab muag tuab, feem ntau pom zoo kom xaiv ib daim ntawv qhia tag nrho.
