Cov Ntsiab Lus Tseem Ceeb Rau Kev Tswj Xyuas Lub Ncauj Ncauj Ncauj Ntim Hnab

Zaj duab xis hnab thickness:conventional 100 microns-160 microns,lub thickness ntawm ntshiab aluminium ntawv ci rau kev siv composite yog feem ntau7microns ua

Ntau lawmcoj lub sijhawm: xav tias yuav muaj li ntawm 12 hnub

Aluminiamzaj duab xis:VMPET yog cov khoom ntim khoom sib xyaw ua ke uas tsim los ntawm plating ib txheej nyias nyias ntawm cov hlau nplaum rau ntawm cov yeeb yaj kiab yas siv cov txheej txheem tshwj xeeb. Qhov kom zoo dua yog cov nyhuv metallic luster, tab sis qhov tsis zoo yog cov khoom tsis zoo.

1. Cov txheej txheem luam ntawv

Los ntawm cov kev xav tau ntawm kev lag luam tam sim no thiab cov neeg siv khoom pom, lub ntsej muag lub ntsej muag yog qhov tseem ceeb suav tias yog cov khoom lag luam siab, yog li cov txheej txheem kho kom zoo nkauj feem ntau sib txawv ntawm cov zaub mov zoo tib yam thiab ntim tshuaj txhua hnub, yam tsawg kawg lawv yog "high-end" cov neeg siv khoom. kev puas siab puas ntsws. Yog li rau kev luam ntawv, noj PET luam ntawv ua piv txwv, qhov tseeb ntawm cov ntawv luam tawm thiab xim xim ntawm nws cov ntawv luam tawm yog tsawg kawg ib theem siab dua li lwm yam kev ntim khoom. Yog hais tias lub teb chaws tus qauv yog qhov tseem ceeb tshaj qhov tseeb yog 0.2 hli, ces qhov thib ob txoj hauj lwm ntawm lub ntsej muag daim npog qhov ncauj ntim hnab luam ntawv yeej yuav tsum tau ua kom tau raws li tus txheej txheem luam ntawv no thiaj li yuav zoo dua hloov mus rau cov neeg yuav tsum tau thiab cov neeg siv khoom xav tau kev pab.

Hais txog qhov sib txawv ntawm cov xim, cov neeg siv khoom rau lub ntsej muag lub ntsej muag ntim kuj tseem nruj dua thiab cov ncauj lus kom ntxaws dua li cov tuam txhab zaub mov zoo tib yam.

Yog li ntawd, nyob rau hauv cov txheej txheem luam ntawv, tuam txhab uas muag uas tsim lub ntsej muag daim npog qhov ncauj yuav tsum tau them sai sai rau kev tswj ntawm luam ntawv thiab xim. Tau kawg, kuj tseem yuav muaj kev xav tau ntau dua rau kev luam ntawv substrates kom hloov mus rau cov qauv luam ntawv siab.

2.txheej txheem lamination

Composite feem ntau tswj peb yam tseem ceeb: sib xyaw wrinkles, puas cov kuab tshuaj residue, composite pitting thiab npuas thiab lwm yam txawv txav. Hauv cov txheej txheem no, peb yam no yog qhov tseem ceeb cuam tshuam rau cov txiaj ntsig ntawm lub ntsej muag lub ntsej muag lub hnab ntim khoom.

(1) Kev sib txhuam wrinkles

Raws li tuaj yeem pom los ntawm cov qauv saum toj no, lub ntsej muag lub ntsej muag lub hnab ntim khoom feem ntau koom nrog kev sib xyaw ntawm cov ntshiab txhuas. Ntshiab aluminium yog dov los ntawm cov hlau ntshiab mus rau hauv cov ntawv nyias nyias zoo li daim ntawv, feem ntau hu ua "aluminium film" hauv kev lag luam. Lub thickness yog nyob nruab nrab ntawm 6.5 thiab 7 μm. Tau kawg, kuj tseem muaj cov yeeb yaj kiab tuab tuab.

Ntshiab aluminium films yog heev yooj yim rau wrinkles, so, los yog tunnels thaum lub sij hawm lamination txheej txheem. Tshwj xeeb tshaj yog rau cov tshuab laminating uas tau txais splice cov ntaub ntawv, vim qhov tsis sib xws ntawm kev sib txuas tsis siv neeg ntawm cov ntawv tseem ceeb, nws yog qhov yooj yim kom tsis sib xws, thiab nws yooj yim heev rau cov yeeb yaj kiab aluminium kom wrinkle ncaj qha tom qab lamination, lossis txawm tuag.

Rau wrinkles, ntawm ib sab, peb tuaj yeem kho lawv hauv cov txheej txheem tom qab kom txo tau qhov poob los ntawm wrinkles. Thaum cov kua nplaum sib xyaw ua kom ruaj khov rau qee lub xeev, rov ua dua yog ib txoj hauv kev, tab sis qhov no tsuas yog ib txoj hauv kev los txo nws; ntawm qhov tod tes, peb tuaj yeem pib los ntawm lub hauv paus. Txo tus nqi ntawm winding. Yog tias koj siv cov ntawv loj dua, cov nyhuv winding yuav zoo dua.

(2) Composite hnyav residue

Txij li thaum lub ntsej muag lub ntsej muag ntim yeej muaj cov aluminized los yog ntshiab txhuas, rau cov khoom sib xyaw, muaj cov aluminized los yog ntshiab txhuas yog kev puas tsuaj rau lub volatilization ntawm cov kuab tshuaj. Qhov no yog vim hais tias cov khoom thaiv ntawm ob qho no muaj zog dua li lwm cov ntaub ntawv dav dav, yog li nws muaj kev cuam tshuam rau cov volatilization ntawm cov kuab tshuaj. Txawm hais tias nws tau hais meej meej nyob rau hauv GB / T10004-2008 "Dry Composite Extrusion Compounding ntawm Yas Composite Films thiab Hnab rau Ntim" tus qauv: Cov qauv no tsis siv rau cov yas zaj duab xis thiab lub hnab ua los ntawm cov ntaub ntawv yas thiab ntawv hauv paus lossis aluminium ntawv ci.

Txawm li cas los xij, tam sim no cov tuam txhab ntim cov npog ntsej muag thiab cov tuam txhab feem ntau kuj siv lub teb chaws tus qauv no ua tus qauv. Rau cov hnab ntawv aluminium, cov qauv no kuj yuav tsum tau, yog li nws yog me ntsis yuam kev.

Tau kawg, lub teb chaws tus qauv tsis muaj qhov yuav tsum tau ua kom pom tseeb, tab sis peb tseem yuav tsum tswj cov kuab tshuaj residues hauv kev tsim khoom tiag tiag. Tom qab tag nrho, qhov no yog ib qho tseem ceeb heev tswj taw tes.

Raws li kev paub txog tus kheej muaj kev txhawj xeeb, nws muaj peev xwm ua tau zoo txhim kho nyob rau hauv cov nqe lus ntawm kev xaiv cov kua nplaum, cov tshuab ua kom ceev, qhov cub kub, thiab cov khoom ntim ntim. Tau kawg, qhov no xav tau kev tshuaj xyuas thiab txhim kho cov cuab yeej tshwj xeeb thiab ib puag ncig tshwj xeeb.

(3) Kev sib xyaw pitting thiab npuas

Qhov teeb meem no kuj tseem muaj feem xyuam rau cov ntshiab txhuas, tshwj xeeb tshaj yog thaum nws yog cov qauv PET / AL, nws yuav tshwm sim ntau dua. Qhov chaw sib xyaw ua ke yuav ua rau ntau qhov "crystal point" zoo li phenomena, lossis zoo li "npub" point-like phenomena. Cov laj thawj tseem ceeb yog raws li hauv qab no:

Hais txog cov khoom siv hauv paus: Kev kho deg ntawm cov khoom siv hauv paus tsis zoo, uas yog nquag pitting thiab npuas; cov khoom siv hauv paus PE muaj cov ntsiab lus siv lead ua ntau dhau thiab loj dhau, uas kuj yog qhov ua rau muaj teeb meem loj. Ntawm qhov tod tes, qhov particle nam ntawm tus number case kuj yog ib qho ntawm cov khoom. Lub leveling zog ntawm cov kua nplaum thiab cov coarser hais ntawm tus number case kuj yuav ua rau muaj teeb meem zoo sib xws thaum lub sij hawm sib txuas.

Tsis tas li ntawd, nyob rau hauv cov nqe lus ntawm lub tshuab ua hauj lwm, thaum cov kuab tshuaj tsis evaporated txaus thiab lub compounding siab tsis txaus, zoo phenomena kuj yuav tshwm sim, txawm lub gluing screen roller yog clogged, los yog muaj txawv teb chaws teeb meem.

Nrhiav cov kev daws teeb meem zoo dua los ntawm qhov saum toj no thiab txiav txim siab lossis tshem tawm lawv raws li lub hom phiaj.

3. Lub hnab ua

Ntawm qhov chaw tswj ntawm cov txheej txheem khoom tiav, peb tsuas yog saib ntawm qhov flatness ntawm lub hnab thiab lub zog thiab cov tsos ntawm ntug sealing.

Nyob rau hauv lub tiav lub hnab ua txheej txheem, smoothness thiab tsos yog kuj nyuaj rau tuav. Vim tias nws cov txheej txheem kawg yog txiav txim siab los ntawm kev siv tshuab, khoom siv, thiab kev ua haujlwm ntawm cov neeg ua haujlwm, cov hnab ntim tau yooj yim heev rau khawb thaum lub sijhawm ua tiav cov khoom tiav, thiab qhov txawv txav xws li cov npoo loj thiab me tuaj yeem tshwm.

Rau lub ntsej muag lub ntsej muag lub hnab uas yuav tsum nruj, cov no yeej tsis tso cai. Txhawm rau daws qhov teeb meem no, peb kuj tseem yuav tswj hwm lub tshuab los ntawm qhov yooj yim tshaj plaws 5S nam los tswj qhov tshwm sim khawb.

Raws li qhov yooj yim tshaj plaws kev tswj hwm ib puag ncig kev cob qhia, kev tu lub tshuab yog ib qho ntawm cov khoom siv yooj yim lav kom paub meej tias lub tshuab huv si thiab tsis muaj cov khoom txawv teb chaws tshwm sim ntawm lub tshuab kom ua haujlwm zoo thiab ua haujlwm zoo. Tau kawg, peb yuav tsum tau hloov pauv qhov tseem ceeb tshaj plaws thiab kev ua haujlwm tshwj xeeb thiab tus cwj pwm ntawm lub tshuab.

Nyob rau hauv cov nqe lus ntawm cov tsos, nyob rau hauv cov nqe lus ntawm ntug sealing yuav tsum tau thiab ntug sealing zog, nws yog feem ntau yuav tsum tau siv ib tug sealing riam nrog finer kev ntxhib los mos los yog txawm ib tug ca sealing riam los nias ntug sealing. Qhov no yog qhov kev thov tshwj xeeb. Nws kuj yog ib qho kev sim loj rau cov neeg ua haujlwm tshuab.
