Vim li cas u {{- Daim iav hloov pauv hloov?

Raws li ib qho siv cov khoom lag luam ua kom zoo nkauj, u {{{} Daim iav zoo li cov khoom siv, thiab los nag thaum tswj cov khoom siv tau nyob ntev. Txawm li cas los xij, hauv cov ntawv thov siv, qee cov u - Daim iav puab tuaj yeem muaj kev sib cav sib haum xeeb. Los ntawm tswvyim cov ntsiab lus, kev sim laus, thiab cov ntaub ntawv sib piv, peb tau txheeb xyuas tus yuam sij rau kev ua thiab qhia meej txog qhov sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv. Qhov no tuaj yeem nkag siab los ntawm plaub yam nram qab no:

1. Ua ntej, nkag mus rau "lub hauv paus tseem ceeb" ntawm cov xim xim thiab kev laus

Txhawm rau kom nkag siab yog vim li cas koj - Daim iav txhaj iav, peb ua ntej yuav tsum tau hais meej ob lub tswv yim tseem ceeb:

1.1 Vim li cas iav muaj xim?

U -} Daim iav puab yog cov khoom siv pob tshab, thiab nws cov xim yog txiav txim siab los ntawm tusPom lub teeb nws tuaj yeem kisCov. Piv txwv li, yog tias lub khob tshwm ntsuab, nws yog vim nws nqus liab thiab xiav lub tshav ntuj thiab tsuas yog tso cai rau lub teeb ntsuab kom ncav cuag peb lub qhov muag. Tshav ntuj muaj tsis yog pom lub teeb (liab, txiv kab ntxwv, daj, ntsuab, thiab lwm yam.ultraviolet (UV) duab- Tus neeg tsav tsheb tseem ceeb ntawm cov iav discoloration.

1.2 Qhov sib xyaw ntawm U {- Daim iav hides ua rau muaj kev pheej hmoo

Cov khoom siv raw rau kev ua ub no u {- Daim iav puab yog cov xuab zeb, uas ib txwm muaj hlau (hauv daim ntawv ntawm ferous ions, fe²⁺), muab cov iav ntsuab tint. Kom kho cov xim no, qee cov tuam ntxhab ntxivLub ntiaj teb tsis tshua muaj Oxidizers(xws li, cerium dioxide), uas tuaj yeem ua rau lub khob me ntsis daj. Lawv tom qab ntawd ntxiv cov tebchaw zoo li Selenium lossis manganese mus nruab nrab ntawm daj, uas ua rau "pos huab dawb" nrog pob tshab ntsuab) nrog kev hloov pauv ntawm lub teeb.

Qhov teeb meem loj dua yog tias tsis tshua muaj lub ntiaj teb Oxidizers yauv tawm "(lub cev nqaij daim tawv"}} Lub Zog Hluav Taws Xob Yog tias u {- Daim iav puab rau cov phab ntsa sib kab lossis phab ntsa sab nrauv, nws yuav ua kom tsis muaj lub ntsej muag thiab tsis muaj lub siab. Ntxiv mus, txij li lub hnub raug tshem tawm txawv ntawm cov kab sib txawv ntawm phab ntsa, "xim tsis sib xws" (qee qhov chaw tsaus thiab lwm qhov sib dua) yuav tshwm sim tom qab ob peb xyoos.

Hauv kev sib piv, feem ntau siv ntab ntab iav (piv txwv li, tsis tu ncua lossis ultras float float cov neeg sawv cev, yog li nws nyuam qhuav discolor vim UV kis tau.

2. Tshawb xyuas nrog kev sim: Koj sib txawv npaum li cas- zoo li cov tsom iav sib txawv?

Txhawm rau saib cov laus ntawm u {{- Daim iav zoo li, peb tau xaiv 3; thiab b; asg yog tsim los ntawm appleton) rau kev sim. Txoj kev ua tau zoo yog "simulate ntev- Tshav ntuj} Lub hnub ci ci rau + Ntsuas kev hloov pauv hauv teeb meem kev sib txuas lus":

2.1 Yuav ua li cas sim ua "cua, tshav ntuj, thiab los nag"? Siv UV Weathering Test Chamber

Peb siv a313-NM Fluorescent Tube UV Weathering Kuaj ChamberCov. Lub luv - wave UV rays nws emits yog muaj zog dua li 3 lub hlis ntawm UV sab nraum zoov ntom ntom ntom. Peb raug cov qauv rau 480 teev (simulating 5 xyoos) thiab 960 teev (simulating 10 xyoo) kom nrawm dua cov kev laus iav.

2.2 Yuav ua li cas ntsuas ntsuas hloov? Siv cov kws tshaj lij kev lag luam Spectrophotometer

Peb siv aShimadzu DridSpec-3700 / 3700Duv Spectrophatometer, uas muaj peev xwm raug ntsuas qhov "teeb ​​meem pauv" ntawm pom lub teeb ntawm txawv wavelengths los ntawm lub khob. Ib qho kev hloov loj dua hauv lub teeb kev hloov pauv tau qhia tau ntau qhov hloov pauv ntawm cov xim xim.

3. Kev sim ua tau: Qhov sib txawv ntawm siab - zoo thiab qis}}} zoo li lub khob yog pom tseeb

Tom qab 960 teev ntawm kev laus (simulating 10 xyoo), 3 hom iav pom qhov sib txawv tseem ceeb:

Asg (appleton) u -} zoo li lub khob: Nws muaj lub teeb ci ntsa iab ntau tshaj plaws kev hloov pauv, tsawg tshaj plaws txo qis tom qab laus tom qab kev laus, yuav luag tsis muaj xim hloov, thiab qhov zoo tshaj plaws.

U {- Daim iav puab ntawm cov chaw tsim khoom a: Nws lub teeb kev hloov pauv tau qis dua li ntawm Asg. Tom qab kev sib txuas, cov kev hloov pauv tau txo ntau dua ntxiv -} Tshwj xeeb tshaj yog rau kev pom lub teeb viret, uas yuav NW nyuam qhuav dhau los. Lub iav muab lub npub daj npub - xim av.

U - Daim iav puab ntawm cov chaw tsim khoom b: Nws muaj qhov qis dua thawj lub teeb rau kev hloov pauv thiab ntsia zoo li nws tau npog nrog ib txheej ntawm huab. Tom qab kev laus, tsis tsuas yog nws hloov chaw ntxiv ntxiv, tab sis nws kuj tig bluish {}} green vim tias lub teeb liab tsis tuaj yeem hla dhau. Cov qauv no muaj cov kev sib txawv tshaj plaws.

Nyob rau hauv luv: U {- Daim iav zoo li tus high thaum pib teeb meem kev hloov pauv tsawg dua tom qab kev laus. Nyob rau hauv sib piv, cov khoom lag luam uas tsis tshua muaj kev hloov chaw (vim ntxiv ntawm qhov qis-} "uglification" tom qab ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos ntawm ob peb xyoos kev siv.

4. Zaum kawg xaus: Thaum xaiv u {- Daim iav puab, tsis txhob tsom rau "tam sim ntawd

Thaum xaiv u {{- Daim iav puab, koj yuav tsum tsis tsuas yog tsom rau nws cov xim thiab pob tshab thaum cov khoom yuav tshiab tab sis kuj tseem ua ntejntev -} lo lus ruaj khov:

Cov khoom lag luam ua ntej nrog kev hloov pauv siab ntawm kev hloov chaw thiab "Crystal -}} ntshiab" tsos. Tsis txhob tsom iav nrog ib qho kev siv lub ntsej muag "famgy tsos" {2} {} Cov iav zoo nkauj ntxiv thiab muaj feem cuam tshuam tom qab.

Ua tib zoo saib seb cov chaw tsim tshuaj paus siv siab - Cov ntaub ntawv hlau zoo (piv txwv, cov tshuaj pleev xim hlau tsis zoo). Nco ntsoov: tus tub ntxhais tseem ceeb ntawm u {{5} Daim iav discoloration yog qhov "tshuaj tiv thaiv kab / tshuaj dawb hauv cov khoom siv raw thiab UV Rays." Therefore, choosing the right product can help avoid troubles like "color unevenness and fading" after a few years of use.

Yog tias koj yuav tsum tau thov cov ntsiab lus no rau cov ntaub ntawv raug cai (xws li cov ntaub ntawv qhia lossis cov lus qhia khoom), Kuv tuaj yeem pab ua kom ua kom tau zooTerminology muaj xwm txheejthiab kho cov qauv kom tau raws li kev kawm lossis cov qauv kev lag luam. Koj puas xav kom kuv ua li ntawd?
