Raws li cov khoom siv, daim iav tuaj yeem muab faib ua daim iav acrylic, daim iav txhuas, daim iav nyiaj thiab daim iav uas tsis yog tooj liab.
Acrylic daim iav, uas nws lub hauv paus phaj yog ua los ntawm PMMA, yog hu ua daim iav nyhuv tom qab lub optical-qib electroplated puag phaj yog nqus coated.Yas lo ntsiab muag yog siv los hloov iav lo ntsiab muag, uas muaj qhov zoo ntawm lub teeb yuag, tsis yooj yim tawg, yooj yim molding thiab ua, thiab xim yooj yim.Feem ntau, nws tuaj yeem ua rau: daim iav ib sab, daim iav ob sab, daim iav nrog cov kua nplaum, daim iav nrog ntawv, semi-lens, thiab lwm yam tuaj yeem ua raws li cov kev xav tau sib txawv.Disadvantages: tsis tuaj yeem tiv taus kub thiab tsis zoo corrosion kuj.Acrylic daim iav muaj qhov tsis xws luag, uas yog, nws yooj yim rau corroded.Thaum nws los rau hauv kev sib cuag nrog roj thiab ntsev, nws yuav corroded thiab distorted nyob rau hauv lub hnub.
Vim tias cov txheej txheem txhuas yog yooj yim rau oxidize, daim iav saum npoo yog tsaus, thiab cov txheej txhuas tsis haum nruj nrog cov iav.Yog tias cov ntug seam tsis nruj, dej yuav nkag los ntawm qhov sib txawv, thiab cov txheej txhuas yuav tev tawm tom qab dej nkag mus, daim iav saum npoo yog yooj yim deform, thiab lub sijhawm ua haujlwm thiab tus nqi kuj qis dua cov iav nyiaj.
Daim iav muab nyiaj muaj lub ntsej muag ci ntsa iab, siab ntom ntawm mercury, yooj yim kom tau txais ntub, yog li feem ntau ntawm cov iav dej muag muag ntawm lub khw yog nyiaj tsom iav.
Daim iav tsis muaj tooj liab tseem hu ua daim iav ib puag ncig.Raws li lub npe qhia, daim iav tsis muaj tooj liab kiag li.Nws yog ib tug tuab passivation tiv thaiv zaj duab xis ntawm cov nyiaj txheej, uas zoo tiv thaiv cov nyiaj txheej ntawm khawb, thiab muaj ib tug ntev kev pab cuam lub neej.Nws suav nrog iav substrate.Ib sab ntawm cov iav substrate yog coated nrog ib tug silver txheej thiab ib tug pleev xim txheej, thiab ib txheej ntawm passivation zaj duab xis yog teem nruab nrab ntawm cov nyiaj txheej thiab cov xim txheej, lub passivating tus neeg saib xyuas zaj duab xis yog tsim los ntawm neutralization cov tshuaj tiv thaiv ntawm aqueous tov ntawm acid ntsev. thiab alkaline ntsev rau saum npoo ntawm cov nyiaj txheej.Cov txheej xim muaj xws li primer siv rau ntawm ib tug passivating tus neeg saib xyuas zaj duab xis thiab ib tug topcoat thov rau primer.
Raws li qhov kev siv, daim iav tuaj yeem muab faib ua cov iav hauv chav dej, cov iav kom zoo nkauj, daim iav puv lub cev, cov iav zoo nkauj, cov iav tshaj tawm, cov iav tsom iav, thiab lwm yam.
