Kev Tsim Khoom Thiab Txoj Cai Ntawm Lub Teeb Qhia Vaj Huam Sib Luag

Lub luag haujlwm tseem ceeb thiab txheej txheem tsim khoom ntawm phaj qhia lub teeb

Lub sij hawm qhia lub teeb phaj los ntawm Lus Txhais Lus Askiv (Lub Teeb Qhia), uas yog tsim thaum siv rau LCD. LCD yog cov khoom uas tsis yog tus kheej-luminous.

Txhawm rau kom pom qhov ci ntawm LCD, cov khoom yuav tsum muaj lub teeb pom kev zoo rov qab los tso saib nws. Lub phaj qhia lub teeb yog ib qho tseem ceeb hauv kev tsim kho lub teeb pom kev zoo.

Nrog kev thov rau cov khoom lag luam nqes hav thiab tom qab ntawd pib muaj kev hloov pauv sib txawv.

Kev ua haujlwm thiab xav tau ntawm lub teeb qhia phaj

Raws li lub npe qhia, lub luag haujlwm tseem ceeb ntawm daim phiaj qhia lub teeb yog coj lub teeb nyob rau hauv qhov kev xav tau los ntawm tus tsim qauv, thiab txhua qhov tsim ntawm lub teeb qhia phaj yog

Txhawm rau ua kom tau raws li qhov xav tau ntawm cov khoom lag luam nqes hav LCD thiab teeb pom kev zoo, qhov tseem ceeb tshaj plaws yog kom ua tiav qhov ci ci thiab zoo ib yam.

Kev faib tawm ntawm daim phiaj qhia teeb

Feem ntau hais lus, daim phiaj qhia teeb pom kev sib txawv vim lawv cov duab, cov txheej txheem tsim khoom thiab cov haujlwm, thiab tam sim no tsis muaj kev faib ua ke. Tom qab sorting:

1. Raws li cov duab, nws tau muab faib ua: phaj tiaj thiab phaj phaj (phaj inclined)

Cov phaj tiaj tus: Lub teeb qhia lub phaj yog duab plaub thaum saib los ntawm qhov pom ntawm qhov teeb meem.

Cov phaj phaj: Los ntawm qhov pom ntawm lub teeb pom kev, ib sab yog tuab thiab lwm sab yog nyias thiab cov duab puab (daim duab peb sab).

2. Raws li dot txheej txheem kev tsim khoom: luam ntawv thiab tsis luam ntawv

Kev Luam Ntawv: Tom qab lub teeb qhia lub phaj ua tiav cov duab ua tiav, cov ntawv teev tseg tau luam tawm ntawm qhov pom kev los ntawm kev luam ntawv, thiab nws tau muab faib ua ob hom: IR thiab UV.

Hom tsis luam ntawv: cov dots tau tsim ncaj qha rau ntawm qhov cuam tshuam thaum lub teeb qhia phaj tau tsim. Nws tau muab faib ua tshuaj etching (Etching), cov yam ntxwv ua haujlwm zoo (V-txiav),

Stamper, sab hauv diffusion.

3. Raws li txoj kev teeb pom kev zoo: sab teeb pom kev zoo (raj thiab LED) thiab lub teeb ncaj ncaj.

Hom-teeb pom kev: Muab lub cev ci (lub raj lossis LED) tso rau sab ntawm lub phaj qhia lub teeb.

Hom ncaj qha: Muab lub cev ci (lub raj lossis LED) nyob hauv qab daim phiaj qhia lub teeb.

4. Raws li txoj hauv kev tsim: txhaj tshuaj thiab txiav cov txheej txheem.

Txhaj tshuaj molding: Siv lub tshuab moulding txhaj tshuaj kho qhov muag qib PMMA rau hauv pwm thaum kub thiab siab kom txias thiab zoo.

Txiav thiab tsim: Cov qib qib PMMA thawj lub rooj tsavxwm raug txiav kom ua tiav cov khoom tiav.

Lub teeb qhia phaj tsim txheej txheem

Ua ntej nkag siab cov txheej txheem txheej txheem, koj yuav tsum xub nkag siab txog cov khoom thiab cov ntaub ntawv xav tau rau lub teeb qhia phaj

1. Cov ntaub ntawv thiab cov cuab yeej xav tau

a Txhaj tshuaj molding: qib kho qhov muag PMMA hais, number case

b. Txiav: kho qhov muag qib PMMA phaj, number case

2. Kho qhov muag qib PMMA hais thiab daim hlau:

Tsis muaj teeb meem dab tsi cov txheej txheem tsim khoom siv, qhov tseem ceeb tshaj plaws thiab cov khoom qub ntawm lub teeb qhia phaj yog qib qib PMMA.

(POLYMETHYL METHACRYLATE) (Polymethacrylate kuj tseem raug hu ua acrylic lossis plexiglass, thiab nws cov kev faib tawm muaj

PMMA hais thiab PMMA daim hlau PMMA yog ua los ntawm cov roj av monomers (MMA) thiab tom qab ntawd cov monomers (MMA) tau siv tshuaj ua kom pom kev

Lub tsev kawm ntawv qib PMMA hais (rau kev txhaj tshuaj twb muaj lawm), thiab tom qab ntawd kho qhov muag-qib PMMA hais tau raug pov tseg lossis txuas ntxiv

(Txhaj Tshuaj) los tsim kho qhov muag-qib PMMA tiaj tiaj. PMMA cov tuam txhab tsim khoom lees paub los ntawm kev lag luam muaj raws li hauv qab no: (Nyiv) Mitsubishi Rei

Yang Mitsubishi Rayon, (Nyij Pooj) Sumitomo Tshuaj Sumitomo, (Nyij Pooj) Asahicasei, (Nyij Pooj) Kuraray, (Taiwan)

Chi Mei Tshuaj, (Han) Shi thiab Sehwa,

3. Ink: faib ua UV thiab IR

4. Cov txheej txheem tsim khoom ntawm lub tiaj txiav lub teeb qhia phaj tau muab faib ua peb ntu:

Thawj yog cov duab ua ntawm daim ntawv acrylic;

Qhov thib ob yog kev tsim tshuaj ntsuam;

Qhov thib peb yog luam ntawv, thiab cov txheej txheem ntws yog

a Acrylic puab ua=thawj lub rooj txiav> daim iav phiaj xwm> tsim ua.

b. Vijtsam tsim tawm=teev tsim> zaj duab xis tso tawm> Nuj Zhang

c. Luam tawm=Acrylic tu> luam ntawv> ci (IR) lossis lub teeb ci ultraviolet (UV)

5. Txhaj tshuaj molding lub teeb qhia phau ntawv phaj tau muab faib ua hom luam ntawv thiab yam tsis luam ntawv, thiab cov txheej txheem yog ib yam nkaus, vim tias hom luam ntawv tsis nyob hauv kev txhaj tshuaj thaum pwm raug pov tseg.

Cov dots tau muab pov rau ntawm lub vijtsam, yog li cov khoom tiav tsuas yog cov duab acrylic. Tom qab tsim cov duab, lub teeb qhia phaj tau ua tiav los ntawm kev luam ntawv. Hom tsis luam ntawv yog

Cov qauv tsim tau muab pov rau ntawm cov pwm kom cov dots thiab phaj qhia lub teeb ua tiav tib lub sijhawm thaum txhaj tshuaj molding.

Kev tshuaj xyuas cov tshuab tsim khoom ntawm lub teeb qhia phaj

1. Khoom siv:

Tam sim no, cov khoom siv ib txwm siv hauv kev lag luam yog PMMA, tab sis qhov tsis txaus ntawm PMMA thiab qhov tsis txaus tam sim no ntawm MMA monomer cov peev txheej tsim khoom

Muaj ntau zaus tsis txaus, yog li qee cov tuam ntxhab tau pib nrhiav lwm cov ntaub ntawv, vim tias daim ntawv qhia lub teeb yog ib feem tseem ceeb ntawm lub teeb ci hauv LCD.

Yog li ntawd, lub teeb pom kev zoo ntawm cov khoom siv yog qhov xwm txheej tseem ceeb heev. Nippon Zeon ntawm Nyij Pooj tau txhawb nqa cov khoom siv tshiab Zeonor cycloolefin nyob rau xyoo tas los no.

Qhov zoo tshaj plaws ntawm cov polymer (Cycio Olefins Polymer, COP) nyob hauv nws qhov qis qis tshwj xeeb thiab cov dej tsis haum piv rau PMMA, tab sis vim Zeonor ua rau

Lub peev xwm tsim khoom ntawm cov chaw tsim khoom tsuas yog 5,000 metric tons rau ntau xyoo. Yog li ntawd, tus nqi tsev yuav luag plaub npaug ntawm PMMA thaum kev ntsuas kev lag luam tsis mus txog.

Xav txog Zeonor' kev sib tw kom zoo dua rau tus nqi tuaj yeem hais tau tias yog kev tso dag xwb. Acrylic xav tau thiab cov ntsiab lus tseem ceeb: qhov loj me, daim iav tiav, kev ncaj ncees, thiab lwm yam

Zoo, khoov, nruj.

2. Kev luam ntawv: txoj kev luam ntawv tau muab faib ua IR thiab UV vim nws txoj kev ziab ziab

Kev sib piv ntawm IR thiab UV yam ntxwv luam ntawv

3. Txoj kev ua:

Muab faib ua peb hom: txiav luam ntawv, txhaj tshuaj molding thiab txhaj tshuaj molding tsis luam ntawv
