Yuav txiav txim qhov zoo thiab qhov tsis zoo ntawm daim iav chav dej?
1. Cov iav thiab hauv qab zoo
Lub iav yuav tsum muab tso rau sab nraub qaum kom siv tau los xav txog. Tam sim no, cov iav ntawm kev ua lag luam feem ntau yog siv nyiaj los yog txhuas raws li txheej txheej ntawm reflex. Ob yam khoom no txawv heev. Feem ntau hais lus, aluminium iav yog qhov ua rau oxidation thiab whitening imaging, yog li lub neej luv yuav luv; Cov iav nyiaj tsis yooj yim rau oxidized, thiab lawv tseem tuaj yeem siv tau ib txwm nyob hauv qhov chaw ntub dej. Vim tias tus nqi ntawm cov iav nyiaj ntau dua li cov iav iav, qee cov tub lag luam yuav siv cov iav iav los tiv thaiv cov iav nyiaj kom tau txais txiaj ntsig loj. Cov neeg siv khoom yuav tsum paub paub qhov txawv:
Saib qhov kev xav clarity
Raws li ib txwm muaj, daim iav nyiaj yog qhov pom tseeb dua li daim iav txhuas, thiab lub teeb pom kev ntawm lub kaum sab xis yog ntau tus qauv; lub reflectance ntawm txhuas daim iav yog tsawg, txog 70 feem pua, thiab nws yog ib qho yooj yim rau distort nyob rau hauv cov duab thiab xim.
Saib cov txheej hauv qab
Cov xim tiv thaiv tom qab daim iav chav dej yog khawb. Yog tias cov txheej hauv qab yog tooj liab, nws ua pov thawj tias nws yog daim iav nyiaj. Yog tias nws yog nyiaj, nws muaj pov thawj los ua ib daim iav aluminium. Feem ntau, sab nraub qaum ntawm daim iav nyiaj yog grey tsaus, thiab lub nraub qaum txheej ntawm daim iav aluminium yog daj ntseg.
Saib ntawm cov xim pleev xim ua haujlwm
Nyiaj tsis yog hlau active, uas tsis yooj yim rau oxidize, thiab txhuas yog active hlau thiab yooj yim rau oxidize. Thaum yuav khoom, koj yuav tsum tau nyob rau hauv kev sib cuag nrog dilute hydrochloric acid. Yog tias cov lus teb tsis pom tseeb, nws ua pov thawj tias nws yog iav nyiaj. Yog tias cov lus teb pom tseeb, nws ua pov thawj tias nws yog iav aluminium.
2. Kev muaj peev xwm ua duab
Cov duab muaj peev xwm ntawm daim iav chav dej yog nyiam los ntawm kev pom tseeb thiab tsis muaj deformation. Koj tuaj yeem siv cov khoom ncaj nraim nyob deb rau kev siv, thiab saib xyuas qhov zoo ntawm ntau lub kaum sab xis ntawm sab xub ntiag, sab, thiab qhov tsis zoo. Nyob rau hauv tsos nrog cov iav zoo zoo, tsis muaj npuas, khib nyiab, tsis tiav, xim-hloov, thiab lwm yam hauv kev txav, cov khoom ncaj nraim yuav tsis khoov thiab deform.
3. Kev tshwm sim
Thaum muas daim iav chav dej, koj tuaj yeem saib seb nws zoo li cas. Feem ntau hais lus, daim iav zoo yuav tsum tsis txhob muaj npuas, impurities, discoloration, tsaus nti, ciam teb dub, thiab lwm yam los ntawm qhov tsos. Yuav tsum tsis muaj tev, pinholes, impurities txuas, khawb, teeb dots, thiab lwm yam.
4. Waterproofing thiab xeb kuj
Lub chav da dej ib puag ncig yog ntub, thiab cov iav tsis zoo hauv chav dej yog muab tso rau hauv ib qho ntawm lub sijhawm. Nws yooj yim rau xeb thiab xim phenomenon nyob rau hauv cov npoo ntawm daim iav. Yog tias koj yuav daim iav hauv chav dej ciam teb, koj yuav tsum ua tib zoo saib seb cov seams ntawm lub lens thiab ciam teb yog nruj. Yog tias muaj cov hlau raug ntau dua hauv daim iav, koj yuav tsum nug cov khoom tshwj xeeb thiab paub meej tias cov khoom siv xeb tuaj yeem yuav.
