Blackening ntawmLED zaub screensyog ib qho tshwm sim.Niaj hnub no, cia saib ob peb lub ntsiab yog vim li cas rau nws blackening.
1. Sulfurization, chlorination, thiab bromination
Cov nyiaj plating txheej ntawm LED zaub bracket yuav tsim cov nyiaj sulfide thaum nws los rau hauv kev sib cuag nrog sulfur-muaj roj, thiab thaum nws los rau hauv kev sib cuag nrog acidic nitrogen-muaj chlorine thiab bromine roj, nws yuav tsim photosensitive nyiaj halide, uas yuav ua rau kom muaj zog. lub teeb qhov chaw tig dub thiab poob.Sulfur / chlorine / bromination ntawm lub teeb ci tuaj yeem tshwm sim hauv txhua theem ntawm kev tsim khoom, kev cia khoom, kev laus, thiab kev siv cov khoom siv hluav taws xob thiab cov teeb ci LED.Tom qab kuaj pom cov sulfur / chlorine / bromination vim blackening ntawm lub teeb ci, cov neeg siv khoom yuav tsum xaiv ib qho kev npaj tshem tawm cov sulfur tshwj xeeb raws li theem uas sulfur / chlorine / bromination tshwm sim.Tam sim no, sulfur / chlorine / bromine nrhiav tau cov haujlwm tsim los ntawm Jinjian suav nrog: teeb sulfur / chlorine / bromine (nrog rau cov khoom siv hauvfais fab mov), teeb sulfur / chlorine / bromine (tsis suav cov khoom siv hluav taws xob sab nraud), cov khoom siv hluav taws xob sulfur / chlorine / bromine, auxiliary khoom sulfur / chlorine / bromine, ntim rhiav sulfur / chlorine / bromine, teeb pom kev rhiav sulfur / chlorine / bromine, thiab reflow soldering Rhiav sulfur / chlorine / bromine.Vim qhov tseeb tias cov pa roj uas muaj cov sulfur, chlorine, thiab bromine tuaj yeem nkag mus rau sab hauv ntawm lub teeb pom kev los ntawm qhov khoob hauv silicone lossis brackets, Jinjian kuj tau tsim cov phiaj xwm kev tshuaj xyuas airtightness ntxiv los pab cov neeg siv khoom txhim kho lawv cov kev xav tau rau cov khoom siv teeb pom kev zoo.
2. Oxidation
Silver yooj yim reacts nrog oxygen nyob rau hauv qhov kub thiab av noo ib puag ncig, ua dub nyiaj oxide.Tom qab lees paub tias yog vim li cas rau blackening ntawm lub teeb ci yog oxidation ntawm cov nyiaj plating txheej, Jin Jian yuav qhia tias cov neeg siv khoom ntxiv ua huab cua nruj xyuas ntawm lub teeb ci thiab teeb kom tshem tawm txoj hauv kev ntawm noo noo infiltration.
3. Carbonization
Raws li kev paub dhau los, cov khoom siv tsis xws luag hauv 6 cov ntaub ntawv tseem ceeb ntawm LED lub teeb qhov chaw (chips, brackets, khoom siv lead ua kua nplaum, cov xov hlau sib txuas, cov hmoov fluorescent, thiab cov kua nplaum ntim) thiab cov txheej txheem tsis xws luag hauv peb cov txheej txheem ntim khoom loj (khoom siv lead ua, xov hlau, thiab gluing) txhua tus tuaj yeem ua rau kub siab heev hauv qhov chaw teeb pom kev zoo, ua rau lub zos lossis tag nrho blackening thiab carbonization ntawm lub teeb ci.Kev tsim hluav taws xob tsis tsim nyog ntawm LED teeb, thermal conductivity ntawm cov khoom siv hluav taws xob tsis zoo, tsis tsim nyog siv hluav taws xob tsim, thiab ntau qhov kev cuam tshuam rov qab tuaj yeem ua rau carbonization ntawm lub teeb ci.Yog li ntawd, thaum Jinjian ua ntej lees paub tias yog vim li cas rau blackening ntawm lub teeb qhov chaw yog carbonization, nws yuav qhia tias cov neeg siv khoom ua raws li LED teeb qhov chaw lossis teeb tsis ua haujlwm tsom xam txoj hauv kev, txheeb xyuas lub teeb ci / teeb, thiab txheeb xyuas qhov chaw ntawm qhov tsis xws luag lossis siab thermal kuj.
4. Tshuaj incompatibility
Qhov blackening ntawm LED teeb qhov chaw kuj yuav tshwm sim los ntawm cov tshuaj lom neeg, thiab qhov tshwm sim blackening no feem ntau tshwm sim nyob rau hauv kaw lub teeb nrog me me los yog tsis muaj cua txaus.
Thaum peb ntsib ib qho xwm txheej uas lub vijtsam LED zaub tig dub, peb tuaj yeem tshawb xyuas qhov laj thawj ntawm ib qho thiab hloov kho.
