Feem ntau tseem ceeb ntawm kev siv ua kua dej ua kom pom tseeb: clearing point; refractive index Δn; qhov pib qhov hluav taws xob; purity; viscosity tas li K; dielectric tas li ε; pitch ρ
Lub cev los ntawm cov khoom siv coj los ua kev sim thiab kev txiav txim siab rau cov kua siv lead ua kua: Resistivity: B. Txiav txim cov txheej xwm: Cov txiaj ntsim tau sim yog nyob rau ntawm cov khoom noj uas yuav tsum tau ua (ntawm lub hoobkas tus qauv ≥ 8X107). Photoelectric zog: A, sim txujci: sim cov khoom, thiab sim nws qhov kev ua tau zoo ntawm photoelectric. B. Cov Kev Txiav Txim Siab: Cov Von thiab Voff qhov kev ntsuas ntawm qhov kev kuaj sim yog qhov zoo ib yam nrog cov khoom siv tsis zoo, thiab qhov pom lub kaum, qhov sib txawv, thiab tom qab muaj xim raws li qhov yuav tsum tau ua ntawm cov khoom muag. Cov ntsiab lus meej meej: A. Kev ntsuas txoj hauv kev: Ua kom cov kua siv ua kua los ntsuas thiab ntsuas qhov kub ntawm qhov uas nws ncav cuag cov ntsiab lus meej. B. Cov Kev Txiav Txim Siab: Qhov ntsuas kub ntawm qhov ntsuas tau zoo npaum li cas nrog lub ntsiab lus ntawm qhov chaw ntsuas tau los ntawm lub chaw muag khoom. UV ua haujlwm: A. Hom tshuaj ntsuam: Cov kua qia tshuaj siv los kuaj yuav raug muab tso rau hauv lub tshuab UV, thiab irradiated ob zaug raws li UV siv sijhawm thiab sijhawm teev los ntawm kev sib khi los kuaj qhov kev hloov pauv hloov tshiab ua ntej thiab tom qab lub irradiation . B. Txiav txim cov txheej xwm: Tom qab UV irradiation, qhov nqi Voff nce li ntawm 0.1V (cov khoom siv qis hluav taws xob tsawg li ntawm 0.15V), tus nqi tam sim no hloov hauv 2 zaug, thiab qhov sib txawv ntawm qhov sib txawv tsis pom tseeb. Kev Ntseeg: A. Kev ntsuam xyuas: Xeem cov kua siv lead ua kua los soj ntsuam thiab ntsuas nws qhov kev ntseeg tau zoo. B. Txiav txim cov txheej xwm: Qhov kev hloov ntawm photoelectric hloov tom qab qhov kev cia siab ntawm kev ntseeg muaj nyob rau hauv cov khoom muag.
Raws li cov hom zaub: TN hom kua siv lead ua, STN hom kua siv lead ua, HTN hom kua siv lead ua kua; raws li cov ntsiab lus ntshiab: cov kua siv ua kua txaj tib, dav hom ua kua dej ua kua;
Cov kev cai xaiv LCD: Raws li tus neeg yuav tsum tau tom qab xim, xaiv qhov tsim nyog Δn ntau ntawm cov kua siv lead ua kua, thiab mam li raws li tus neeg mob IC Circuit Court cov ntaub ntawv, xaiv qhov tsim nyog voltage ntau ntawm cov kua siv lead ua kua, ua tau raws li cov xwm txheej ntawm cov kua Crystal, raws li ib feem tsim nyog muaj txiaj ntsig Tom qab siv, koj muaj peev xwm ua tau raws li tus neeg yuav tsum tau muaj.
Yuav ua li cas kom siv cov kua siv lead ua kua: Cov kua siv lead ua kua yuav tsum ua kom siab hlo ua ntej yuav siv mus rau nws. Ntxiv kua siv lead ua los ntawm cov neeg muaj kabmob, kub kom 60 degrees Celsius, tom qab txias kom sov thiab sov zoo. Tsis tas li ntawd, nws tsis tuaj yeem sab laug ntev ntev thaum siv. Tshwj xeeb tshaj yog rau cov muaj qis rau cov qis muaj zog, vim cov qis muaj zog muaj cov xim sib txawv, cov nram qab no yuav tsum tau mloog zoo rau thaum siv cov kua cov nplais ua kua: Cov kua siv lead ua yuav tsum tau qoos kom ua ntej siv, thiab cov kua siv lead ua yuav tsum muab tso rau hauv ntau lawm tam sim thiab minimized. Cia kom cia lub sij hawm cia kom tsis txhob chromatographic phenomena. Cov kua siv ua kua yuav tsum tau muab npog ntsej muag thiab muab khaws cia kom ntau li ntau tau hauv ib qho haujlwm (yim teev). Cov khoom siv ua kua tsis tau tiav yuav tsum tau rov qab siv dua thiab rov kuaj dua rau qhov hluav taws xob. Feem ntau, raws li lub sij hawm nce, tus tsav tsheb muaj zog nce. Tom qab cov kua siv lead ua los ntawm lub raj mis thawj, yuav tsum tau them rau lub raj mis thiab yuav tsum muab khi rau lub sijhawm kom txo tau lub sij hawm muaj huab cua. Lub sij hawm uas tuaj rau saum cua yog feem ntau dhau lawm ntev, uas yuav ua rau kom cov kua qaub ntawm cov kua siv ua kua. Cov kua crystal display khoob lub thawv ntim rau qhov pib qhov hluav taws xob yog qhov zoo tshaj plaws los ntawm PI cov khoom ci rau cov txheej txheem ua kua, thiab lub thawv ntim nrog lub sij hawm ntev hauv 24 teev, thiab kev sau ua haujlwm feem ntau siv lub sijhawm tsawg tsawg . Qhov qis uas muaj qhov qis uas tsis tshua muaj zog yuav tsum tau them nrog lub hood uas tsim nyog siv thaum sib khi, thiab yuav tsum ceev cia ntawm qhov chaw ultraviolet kom ntau li ntau tau thaum lub sij hawm tag nrho cov kua siv lead ua puv hnub tshwj tsis yog thaum lub sij hawm tua ntawm cov kua nplaum sealing. Txwv tsis pub, qhov kev coj tsis ncaj ncees thiab qhov nce ntawm qhov pib qhov hluav taws xob yuav tshwm sim nyob ze ntawm txoj kab hluav taws xob ultraviolet. Cov dej ua kua yog ib hom tshuaj organic polymer, uas yog yooj yim yaj hauv ntau cov tshuaj los yog cov tshuaj reacts nrog lwm cov tshuaj. Cov dej ua kua siv kuj yog ib qho hnyav, ces nws yuav tsum tau ceev cia ntawm lwm qhov thaum siv thiab cia.
