Vim yog lawv lub teeb ci siab thiab tshwj xeeb optical cov khoom, fluorescent pigments yog dav siv nyob rau hauv cov txheej txheej, thiab luam ntawv thov. Txawm li cas los xij, lawv daim ntawv thov cov txheej txheem chaw tsim nyog yuav tsum muaj ntawm cov kev mob ib puag ncig, cov khoom siv cov khoom siv thiab cov txheej txheem ua haujlwm. Cov txheej txheem qauv yuav tsum tau ua raws li kom ntseeg tau tias cov xim ruaj khov thiab lub peev xwm ntawm cov khoom tiav.
Ua ntej -} daim ntawv thov npaj
Daim ntawv thov ib puag ncig yuav tsum tau huv thiab qhuav, nrog rau qhov kub ntawm 15 {- 30℃thiab ib tug txheeb ze humidity hauv qab 70%. Zam kev kub thiab cov av noo uas yuav ua rau muaj kev lom zem los yog txo cov txheej txheem nplaum. Lub substrate nto yuav tsum ua kom huv thiab qhuav, dawb ntawm cov roj, plua plav, thiab lwm yam tsis huv. Rau kev siv hlau, ua ntej-phosphating lossis passivation kev kho mob yog pom zoo los txhim kho adhesion.
Cov khoom siv sib tw thiab sib xyaw
Fluorescent pigments feem ntau yog feem ntau sib xyaw nrog pob tshab lossis lub teeb {{{}}} xim raber (xws li resin lossis hnyav). Qhov kev sib ntxiv yuav tsum nruj ua raws li cov khw muag khoom tau pom zoo tus nqi (feem ntau 1% -5% los ntawm qhov hnyav). Kev ntxiv ntau dhau yuav ua rau muaj kev sib zog txo fluorescence lossis tsis zoo ntawm cov txheej txheej lub cev. Kev sib xyaw yuav tsum tau ua nyob rau ntawm qhov tsis tshua muaj stirring ceev (tsawg dua los yog sib npaug ntawm 300 rpm) kom tsis txhob muaj kev puas tsuaj loj uas tuaj yeem ua rau cov qauv siv lead ua. Nws raug nquahu kom siv cov hlau stainless lossis cov iav ntim iav; Zam txhob siv cov cuab yeej hlau los tiv thaiv kev coj noj tshuaj. Tom qab sib tov, cia cov sib tov kom zaum rau 10-15 feeb los tshem tawm cov pa npuas.
Cov Txheej Txheem Txheej Yuav Tsum
Xaiv txau, txhuam, lossis cov txheej txheej cov menyuam nyob ntawm daim ntawv thov. Ua kom muaj kev phom sij phom sij (0.3 - 0.}} 0.}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Thaum ua ntawv thov ntau lub tsho loj, pub tsawg kawg 10 feeb ntawm txhua lub tsho tiv no (xa mus rau cov lus qhia cov khoom lag luam rau cov ntsiab lus). Cov kev pom zoo kawg coating tuab yog 15-25 μm. UV-curable fluorescent txheej puv rau UV lub teeb (feem ntau 2-5 feeb) los xyuas kom tiav cov crosslinking tag nrho.
Kev tswj kom zoo thiab ceev faj
Tom qab daim ntawv thov, kho tau 24 teev nyob rau hauv cov qauv txheej txheem (23 ± 2 degree, 50 ± 5% Rh) ua ntej kev sim tshuaj. Tsom rau kev kuaj pom lub ntsej muag zoo nkauj ci ntsa iab zoo nkauj, hla (hla kev ntsuas siab dua lossis muaj kev ntsuas ntau dua li 500 teev). Muab cov xim uas tsis tshuav nyob hauv cov thawv ntim kaw kom deb ntawm lub teeb, kub, thiab oxidizing cov neeg sawv cev.
Ua raws li cov qauv no yuav ua kom tiav cov txiaj ntsig zoo ntawm fluorescent, kom ua tiav cov khoom siv zoo thiab ntev ntawm cov khoom tiav.
