Yooj yim paub txog polarizing zaj duab xis


1.Definition ntawm polarizing zaj duab xis

Ntuj kaj:

Lub teeb yog ib qho electromagnetic nthwv dej nyob rau hauv uas nws tsis thiab ntub hlau tsis muaj peev xwm raug muab sib cais los ntawm txhua lwm yam. Qhov peb ntawm peb yog txoj kev sib raug zoo ntawm cov hluav taws xob (E), qhov sib nqus field (H) thiab kev coj ntawm lub tshuab electromagnetic yoj (K).
Feem ntau, lub teeb ci ntuj yog lub teeb nthwv nthwv dej vibrating nyob rau hauv cov kev taw qhia ntawm 360 degrees, thiab yog kiag li teeb nyob rau hauv cov kev taw qhia ntawm 360 degrees. Peb hu nws lub teeb uas tsis muaj teeb meem.

Yuav kom tau lub teeb ntsuab, peb feem ntau xav tau ib co khoom siv, uas tau raug muab faib rau cov hom nram qab no:

  (1) xav txog hom:
Thaum lub teeb yog tig mus rau saum npoo ntawm iav, lub teeb pom kev zoo yuav tsum yog ib feem ntawm polarized. Los ntawm kev siv lub nruam seem ntawm cov iav ntau lub iav, qhov tsis yog lub teeb ci taws tuaj yeem hloov mus rau hauv lub teeb nrug lub cev.
(2) txoj haujlwm yooj yim
Ob daim khob cij muaj calcite raug sib koom ua ke, thiab qhov teeb meem yog teeb tuaj rau hauv ob lub teeb liab, uas hu ua teeb pom kev zoo thiab txawv txawv.
(3) ob lub chromatic microcrystalline
Cov iav me me nrog ob lub xim yog cov xwm yeem tawm hauv cov ntawv pob tshab. Qhov no yog thawj txoj kev thaij duab ua los ntawm tus txiv neej.
(4) ob chromaticity ntawm polymer
Siv lub tshuab zoo polarizing polymer, cov intramenoid molecules yog qhia thiab adsorbed nrog ob chromaticity tshuaj. Cov hom tshuaj polarization muaj nyob rau hauv daim ntawv ntawm Plate or Sheet lossis Film, ces nws feem ntau hu ua polarising (Polarising Phaj lossis Sheet) los yog ib zaj duab xis Polarizing (Polarizing Film). ). Lwm lub sij hawm siv lus Askiv yog (Polarizing Filter).


Cov yam ntxwv ntawm lub ncov qaumteb qab zib: Hloov lub teeb uas tsis muaj qhov sib txawv rau hauv lub teeb ntsuab

1. Thaum cov pa taws kub qis thiab sab nraud yog sib tshooj rau ib leeg, lub teeb tuaj yeem tshwm ntsej muag tsis muaj qhov siv qhov hluav taws xob.

    2.Thaum ua raws li qhov siv hluav taws xob, lub teeb tau thaiv tag nrho kom pom lub xeev tsaus nti.


3. hom polarizing zaj duab xis

   Tam sim no, muaj ntau hom polarizers nyob rau hauv lub lag luam, tab sis raws li lawv cov ntaub ntawv polarizing, lawv muaj tsuas yog classified rau cov nram qab no pawg:

(1) hlau polarizing zaj duab xis
Cov hlau ntsev xws li kub, nyiaj thiab hlau yog adsorbed nyob rau hauv zaj duab xis polymer thiab ces txo kom cov pas nrig li hlau ib kem. Tam sim no, tsuas yog ib co reflector tuaj yeem siv.
(2) iodized polarizing film
Cov iodine molecules yog adsorbed on PVA thiab ces ncua rau orientate lawv, kom lawv tau polarized kho qhov muag thaj chaw. Nws yog ib qho ntawm cov hom kev lag luam polarizer, thiab nws cov cuab yeej siv tshuab tau hlob. Qhov kom zoo dua yog tias qhov kev xa tawm thiab qhov kev sib txawv ntawm polarization yog siab, thiab qhov kawm ntawm polarization ntawm qhov theoretical value yog ze li ntawm 100% thiab qhov kev xa tawm yog 50%. Qhov tsis zoo yog tias kev ua haujlwm ntawm polarization ntawm iodine molecule yog yooj yim puas hauv cov kub thiab siab, thiab cov huab cua tsis zoo .
(3) polarizing zaj duab xis ntawm cov xim zas
Organic dyes nrog ob xim tau adsorbed mus rau PVA thiab ces ncua rau orientate lawv, kom lawv tau ib nrab kev sib hloov khoom. Nws yog ib qho tseem ceeb ntawm kev ua lag luam polarizer. Qhov zoo yog cov huab cua ua haujlwm tsis zoo, feem ntau siv rau cov khoom uas muaj kev cia siab, tab sis nws tsis yooj yim rau kev kawm siab ntawm polarization thiab transmittance, thiab tus nqi siab tshaj li ntawm iodine molecule polarizer.
(4) polythene polarizing zaj duab xis
Siv acid ua catalyst, PVA yog dehydrated, kom PVA molecules muaj ib qhov nqi ntawm ethylene qauv, thiab ces ncua rau orientate, kom nws muaj ib nrab rotation zog. Tam sim no, lub tshuab tsis yog paub tab thiab tsawg dua thov .

4.Cov qauv ntawm cov polaroid

PVA: PVA membrane yog ib hom polymer, uas yog dyed nrog ob chromatic organic dyes. Nyob rau tib lub sij hawm, nws yog ncua nyob rau hauv qee lub voj thiab kub ntawm tej yam kev mob, thiaj li hais tias nws absorbs ob xim dyes rau daim ntawv polarization thaj chaw. Tom qab lub cev qhuav dej thiab ziab khaub ncaws lawm, thawj tus yeeb yaj kiab uas muaj Polarizer tau tsim.

TAC: PVA zaj duab xis muaj cov cuab yeej hydrophilic. Nyob rau hauv qhov chaw kub thiab txias, nws yuav ua sai sai deform, ntsws, so kom txaus, poob, thiab muaj qhov tsis tshua muaj zog, nkig thiab tawg, tsis yoojyim siv thiab txheej txheem. Yog li ntawd, ib txheej ntawm TAC cov yeeb yaj duab nrog kev siv siab, kev xa tawm siab thiab tshav kub tuaj yeem ua ke ntawm ob sab ntawm daim nyias nyias.
