Ib, Cov yam ntxwv ntawm cov khoom thiab kev puas tsuaj mechanism ntawm LCD cov ntxaij vab tshaus
1. Kev txheeb xyuas qhov saum npoo
Niaj hnub nimno ntsuas LCD cov ntxaij vab tshaus feem ntau txais yuav ntau- txheej txheej txheej:
Polarizing zaj duab xis txheej: muaj li ntawm polyvinyl cawv (PVA) thiab cellulose triacetate (TAC) composite, nrog ib tug hardness ntawm tsuas yog 2-3H (miv hardness), yooj yim khawb los ntawm cov khoom ntse.
Txheej txheej: siv indium tin oxide (ITO) nyias zaj duab xis nrog lub thickness ntawm 100-200nm, rhiab heev rau tshuaj corrosion.
Cov txheej txheem tiv thaiv: suav nrog kev tiv thaiv kev cuam tshuam (AR), tiv thaiv ntiv tes (AF), thiab tiv thaiv glare (AG) txheej, uas feem ntau yog tsim los ntawm fluoropolymer nrog qhov sib txawv tseem ceeb hauv cov kuab tshuaj tiv thaiv.
2. Hom kev raug mob
Mechanical khawb: khawb ntawm qhov chaw los ntawm cov khoom me me (xws li SiO ₂ hauv plua plav) thaum so, ua rau pom qhov muag tsis pom lossis lub teeb to.
Tshuaj lom neeg corrosion: Muaj zog alkaline ntxuav cov neeg ua haujlwm tuaj yeem ua rau ITO conductive txheej, ua rau kov tsis ua haujlwm; Acetone muaj cov kuab tshuaj tuaj yeem yaj cov tshuaj fluorine- muaj cov coatings, txo lawv cov kev cuam tshuam kev cuam tshuam.
Kev puas tsuaj zoo li qub: Siv cov ntaub paj rwb tsis tu ncua los so tej zaum yuav tsim hluav taws xob zoo li qub, rhuav tshem cov khoom siv hauv cov kua siv lead ua kua, thiab tsim cov chaw tsaus nti.
2, Kev xaiv cov tshuaj ntxuav tu
1. Hom hnyav thiab siv tau
Hom kuab tshuaj sawv cev rau cov ntsiab lus txaus ntshai ntawm cov khoom siv scenarios
Ultra ntshiab dej DI Dej yog nquag tawm hauv dej cim tom qab txhua hnub tshem tawm plua plav thiab evaporation ntawm me ntsis stains
Isopropanol (IPA) 70% IPA cov tshuaj yuav yaj qee cov coatings vim oily stains thiab siab ntau ntawm cov ntiv tes
Tus neeg saib xyuas tshwj xeeb 3M Novec 72DA precision ntsuas, nrog coated screen, tus nqi siab
Ammonia tov iav ntxuav, alkaline ib puag ncig tiv thaiv kev tshuaj ntsuam, ua rau ITO conductive txheej
Cov lus pom zoo:
Kev tu txhua hnub: Ultra ntshiab dej +0.5% sodium dodecyl sulfate (SDS) surfactant, pH tswj ntawm 6.5-7.5.
Hnyav stains: 70% isopropanol tov, compatibility yuav tsum tau sim nyob rau hauv lub ces kaum ua ntej.
Cov khoom siv kho mob: Cov tshuaj ntxuav dej tsis muaj cawv uas ua raws li ISO 10993 biocompatibility qauv.
2. Daim ntawv teev cov tshuaj txwv tsis pub
Acetone / MEK: Dissolves fluorinated coatings, ua rau txo qis hauv kev ua haujlwm tiv thaiv kev cuam tshuam.
Cov tshuaj chlorine uas muaj cov kuab tshuaj, xws li dichloromethane, tuaj yeem corrode aluminium alloy thav duab.
Muaj zog acid / muaj zog alkali: daws nrog pH qhov tseem ceeb<4 or>10 yuav ua puas lub polarizer.
Sib tsoo cov khoom, xws li calcium carbonate hauv cov tshuaj txhuam hniav, tuaj yeem ua rau micro khawb.
3, Kev tu cov cuab yeej kev teeb tsa
1. Kev xaiv cov ntaub so ntswg
Ultra nplua fiber ntau: Pom zoo 3M 9080 series, fiber ntau txoj kab uas hla Tsawg dua lossis sib npaug li 0.5 μ m, tuaj yeem ntes 99.97% ntawm 0.3 μ m hais.
Daim ntawv tsis muaj plua plav: Xaiv qib M-3 (tsawg dua lossis sib npaug ntawm 100 cov khoom ib square meter Ntau dua lossis sib npaug li 0.5 μ m), xws li Kimtech So series.
Foam stick: siv los ntxuav lub ntug qhov sib txawv ntawm lub vijtsam, yuav tsum muaj kev tiv thaiv - hom zoo li qub.
Cov lus qhia siv:
Tsis txhob rov siv cov ntaub so, thiab thaj chaw rau kev tu ib leeg yuav tsum tsis pub tshaj 10cm ².
Ua ntej so, quav cov ntaub rau hauv 8 txheej kom paub meej tias qhov chaw sib cuag ntawm txhua txheej.
2. Cov cuab yeej pabcuam
Ionic ntxuam: Ua ntej ntxuav, siv ESD-200A ion kiv cua kom tsis txhob muaj hluav taws xob zoo li qub thiab tiv thaiv plua plav adsorption.
Kev tshuaj ntsuam xyuas lub tshuab ntsuas tshuab: Tom qab ntxuav, siv 500x lub tshuab kuaj kab mob los kuaj xyuas qhov chaw kom paub tseeb tias tsis muaj qhov seem seem.
Humidity tswj lub thawv: Ntxuav hauv ib puag ncig nrog cov av noo<30% to reduce static electricity generation.
4, Cov txheej txheem ua haujlwm tau zoo
1. Preprocessing theem
Fais fab kev khiav hauj lwm: tua lub hwj chim ntaus ntawv, unplug lub hwj chim plug los tiv thaiv hluav taws xob zoo li qub puas.
Kev npaj ib puag ncig: cais thaj chaw ua haujlwm hauv chav huv huv (Class 1000 lossis qis dua) lossis nrog cov plua plav npog.
Kev tshem tawm plua plav: Siv cov txhuam txhuam mos (xws li ESD txhuam hniav zoo) kom maj mam cheb lub vijtsam saum npoo ntawm tib qho kev taw qhia kom tshem tawm cov plua plav loj.
2. Kev ntxuav theem
Txau tus neeg saib xyuas: Txau tus neeg saib xyuas mus rau hauv daim ntaub so (es tsis txhob muab tshuaj tsuag ncaj qha rau ntawm lub vijtsam), nrog rau kev siv tshuaj ntawm 0.1ml / cm².
Wiping txoj kev:
Siv ib qho "S" - zoo li txoj hauv kev kom muab kauv so ntawm qhov nruab nrab ntawm lub vijtsam sab nraud.
Tom qab so vertically, nws yuav tsum tau hla so ib zaug ntawm lub kaum sab xis 45 degree.
Kev tswj lub siab: Saib xyuas nrog lub ntsuas ntsuas digital, so lub siab tsawg dua lossis sib npaug li 2N / cm² (kwv yees li 200g qhov hnyav).
3. Tom qab ua tiav theem
Kev kho kom qhuav: Siv cov ntaub ntub dej ultra- cov ntaub fiber ntau kom maj mam so raws txoj hauv kev qub kom tshem tawm cov kua dej uas seem.
Kev kuaj ua haujlwm:
Kev kuaj pom: Txheeb xyuas qhov kaj, qhov chaw tsaus, lossis xim txawv.
Kov kev sim (yog tias tsim nyog): Tshawb xyuas cov lus teb rhiab heev uas siv tus ntsuas kov ntau.
Cov ntaub ntawv khaws cia: Sau rau hauv daim ntawv tu cov ntaub ntawv, suav nrog cov ntaub ntawv xws li hnub tim, tus neeg saib xyuas tu batch, tus neeg teb xov tooj, thiab lwm yam.
5, Tshwj xeeb scenario tuav txoj kev npaj
1. Cov khoom siv kho mob tshuaj ntsuam
Kev siv tshuaj tua kab mob: 75% ethanol lossis quaternary ammonium ntsev tshuaj tua kab mob yuav tsum tau siv, nrog lub sijhawm ua haujlwm tsawg dua lossis sib npaug li 30 vib nas this.
Kev tiv thaiv kev tiv thaiv: Tam sim ntawd yaug nrog dej ultrapure tom qab ntxuav thiab siv cov tshuaj qib silicone roj tiv thaiv txheej.
2. Sab nraum zoov ntsuas qhov screen
Kev tiv thaiv xuab zeb: Ua ntej, siv rab phom cua siab tsawg (siab dua lossis sib npaug li 0.2MPa) los tshuab cov xuab zeb, thiab tom qab ntawd ntxuav raws li cov txheej txheem txheej txheem.
Kev ntsuas dej tsis zoo: Tom qab ntxuav, ua qhov ntsuas dej tsis zoo IP65 kom ntseeg tau tias lub sealing tsis puas.
3. Aerospace khoom
Kev hloov pauv ib puag ncig lub tshuab nqus tsev: Xaiv cov tshuaj ntxuav tsis muaj hluav taws xob tsawg (VOC<50ppm) to prevent pollution of the cabin environment.
Kev tiv thaiv hluav taws xob: Tom qab ntxuav, nws yuav tsum tau siv lub ntsuas hluav taws xob gamma kom paub tseeb tias tsis muaj hluav taws xob seem.
