Cov khoom tseem ceeb ntawm lub iav tsom iav txiav txim siab nws cov tsos, kev nplij siab, thiab kav ntev. Cov khoom sib txawv muaj lawv tus kheej qhov zoo ntawm qhov hnyav, lub zog, malleability, thiab style. Kev xaiv cov khoom siv yuav tsum yog raws li kev xav tau ntawm kev siv thiab kev nyiam ntawm tus kheej. Kev nkag siab txog cov yam ntxwv ntawm ntau yam ntaub ntawv pab nrhiav cov thav ntawv uas ua tau raws li koj xav tau los ntawm ntau yam khoom.
Hlau yog ib qho kev xaiv classic rau cov iav tsom iav, feem ntau suav nrog stainless hlau, npib tsib xee alloys, ntshiab titanium, thiab titanium alloys. Cov ntaub ntawv no muaj zog thiab corrosion- tiv taus, tso cai rau kev tsim cov thav duab slim tsis tau ruaj khov, haum rau cov neeg hnav uas nyiam qhov hnyav thiab ua haujlwm ntev. Titanium, due to its low density and excellent elasticity, is widely used in high-end frames, significantly reducing pressure on the bridge of the nose and ears while maintaining structural stability. Hlau thav duab tuaj yeem ua tau electroplated, sandblasted, los yog txhuam kom ua tiav ntau yam kev pom zoo xws li matte, glossy, lossis gradient tiav. Txawm li cas los xij, nws yuav tsum raug sau tseg tias qee tus neeg yuav muaj kev tsis haum tshuaj rau cov khoom xws li npib tsib xee.
Acetate thiab txhaj tshuaj- cov ntaub ntawv molded muaj ntau yam xim thiab textures. Cov ntaub ntawv muaj xws li cellulose acetate, celluloid, thiab TR90. Celluloid, ua los ntawm cov nroj tsuag ntuj fibers, muaj ib tug sov so zoo nkauj thiab yog ib qho yooj yim rau zas, tsim tej yam ntuj tso textures xws li ntoo grain thiab marble, combining ib tug retro xav nrog ib tug artistic kov. Celluloid boasts cov xim nplua nuj tab sis kuj hnyav, feem ntau siv hauv vintage lossis zoo nkauj heev. TR90 yog cov khoom siv nylon siab -polymer, yoog raws, cuam tshuam- tiv taus, thiab hnyav heev. Nws rebounds nyob rau hauv siab, ua rau nws haum rau cov kev ua si los yog cov me nyuam lub thav duab, muab qhov tsawg kawg nkaus siab txawm tias tom qab ntev hnav.
Kev siv cov khoom sib xyaw ua ke nthuav tawm qhov muaj peev xwm ntawm cov thav duab. Piv txwv li, npog lub thav duab hlau nrog acetate veneer los yog embedding ib tug hlau core nyob rau hauv ib qho kev txhaj tshuaj- molded thav duab los txhawb cov kev ntxhov siab tseem ceeb. Qhov kev sib xyaw ua ke no khaws lub zog ntawm cov hlau thaum siv cov xim thiab kev ntxhib los mos zoo ntawm acetate, ua tiav qhov sib npaug ntawm kev ua haujlwm thiab kev zoo nkauj.
Cov ntaub ntawv ntuj xws li ntoo thiab xyoob yog nce nkag mus rau lub khw muag iav tsom iav. Lawv qhov tshwj xeeb textures thiab eco- cov khoom muaj txiaj ntsig nyiam cov neeg uas muaj txiaj ntsig zoo nkauj, tab sis lawv feem ntau xav tau cov resin los yog lwm yam txheej txheej tiv thaiv los txhim kho cov kav ntev thiab ya raws.
Zuag qhia tag nrho, cov ntaub ntawv tseem ceeb rau cov iav tsom iav suav nrog hlau, acetate thiab txhaj tshuaj- molded, sib xyaw, thiab cov khoom siv ntuj, txhua tus muaj nws lub cev thiab cov yam ntxwv zoo nkauj. Thaum xaiv cov khoom siv, ib tus tuaj yeem sib npaug qhov hnyav, lub zog, tawv nqaij - kev phooj ywg, thiab tsim kev ywj pheej, tso cai rau tus ncej los muab kev txhawb nqa ruaj khov thaum tseem qhia txog tus cwj pwm thiab muab kev nyiam hnav.
