Lub ntsiab tseem ceeb ntawm daim ntawv thaub qab yog ultrafine ntoo fiber ntau. Thaum lub sij hawm luam ntawv, cov muab tub lim tau ntxiv, thiab cov nplaum yog siv los khi cov fibers thiab cov fillers ua ke, tsim cov ntawv liner los ntawm ntau qhov nias. Thaum lub sij hawm nias, muaj cov pores me me ntawm cov ntoo fibers, fillers, thiab adhesives, nrog qee cov dej noo nyob nruab nrab ntawm lawv. Raws li ib puag ncig kub thiab av noo hloov pauv, cov pores no nqus thiab tso cov dej noo rau hauv huab cua. Raws li ib txwm muaj, cov dej noo ntawm daim ntawv liner yog 5.0% ± 1.5%. Yog tias cov dej noo siab dhau lawm, daim ntawv liner yuav wrinkle thaum rewinding; Yog tias cov dej noo tsawg dhau, cov ntaub ntawv hauv ob sab phlu elongation thiab breakage tus nqi txo, ua rau nws yooj yim tawg thaum siv.

Aluminium ntawv ci yog txheej txheej ntawm daim ntawv hauv ob sab phlu, du nrog qee yam hlau ductility thiab xim hlau luster, nrog lub thickness ntawm 0.006mm, zoo heev number case adhesion, thiab tsawg heev cuam tshuam los ntawm ib puag ncig kub thiab av noo. Ink yog cov kua resin uas disperses pigment hmoov, muab faib ua dej -soluble thiab fat- soluble hom, luam tawm nyob rau saum npoo ntawm txhuas ntawv ci los txhim kho qhov zoo nkauj ntawm daim ntawv liner.

Lub luag haujlwm tseem ceeb ntawm adhesives yog sib txuas cov ntawv thaub qab thiab aluminium ntawv ci rau hauv ib chav tsev, thiab muab faib ua cov nplaum nplaum ntub dej thiab cov nplaum nplaum qhuav. Lub ntsiab tseem ceeb ntawm cov nplaum nplaum ntub dej yog acrylic emulsion, thaum qhuav - hom laminating nplaum feem ntau muaj cov khoom siv hauv paus, curing agent, thinner, thiab lwm yam additives. Cov khoom siv hauv paus feem ntau yog tsim los ntawm cov polymers xws li polyurethane, polyester, thiab acrylic, uas muaj adhesion zoo thiab adhesion. Cov neeg ua haujlwm kho cov tshuaj tiv thaiv nrog cov pab pawg ua haujlwm hauv cov khoom siv hauv paus, ua rau cov nplaum kho rau hauv cov yeeb yaj kiab, uas muaj kev cuam tshuam loj rau kev kho ceev, qib, thiab lub zog ntawm cov nplaum. Thinner feem ntau yog siv los kho viscosity thiab txhim kho flowability, txhim khu kev nkag mus thiab wettability ntawm cov nplaum.

Nyob rau hauv muaj pes tsawg leeg ntawm liner daim ntawv, adhesives, txhuas ntawv ci, thiab number case yog kuj ruaj khov thiab tsawg cuam tshuam los ntawm ib puag ncig yam; Cov ntaub ntawv thaub qab tau cuam tshuam zoo heev los ntawm ib puag ncig, nrog kev hloov pauv loj. Kev hloov dej noo ntawm cov ntaub ntawv hauv ob sab phlu yog qhov ua rau lub ntsiab ntawm curling ntawm daim ntawv hauv ob sab phlu, ua raws li slitting nro.

01/ Moisture hloov hauv daim ntawv thaub qab

Lub ntsiab tseem ceeb ntawm cov ntaub ntawv thaub qab, fibers, yog rhiab heev rau kev hloov ntawm ib puag ncig cov av noo. Thaum ib qho fiber ntau absorbs dej thiab nthuav los yog shrinks tom qab poob dej, cov fiber ntau hloov, ua rau muaj kev hloov pauv ntawm daim ntawv loj. Rau cov fibers, kev hloov ntawm cov av noo ua rau qhov hloov pauv ntawm qhov ntev ntawm cov fibers ntawm tsawg dua 1%, tab sis tuaj yeem ncav cuag 20% ​​~ 30% radially.

Daim ntawv liner absorbs noo noo, cov ntaub ntawv rov qab nthuav dav, thiab aluminium foil nto tseem nyob ruaj khov. Raws li lub hauv paus ntsiab lus ntawm cov nplooj ntawv bimetallic, daim ntawv liner khoov mus rau qhov chaw txhuas, raws li pom hauv daim duab 2; Cov ntaub ntawv hauv ob sab phlu tso tawm cov dej noo, cov ntaub ntawv hauv ob sab phlu shrinks, thiab cov ntaub ntawv liner khoov mus rau qhov chaw nraub qaum, raws li pom hauv daim duab 3. Cov dej noo yog qhov ua rau lub ntsiab ntawm qhov curling ntawm daim ntawv hauv ob sab phlu.

Qhov kev ntsuas no tsawg- nqi, tab sis thaum ib puag ncig kub thiab av noo hloov pauv, nws nyuaj rau khaws cov dej tsis tu ncua.

02/ Ntxiv ib txheej txheej

Thaum lub sij hawm tsim khoom, ntxiv cov txheej txheej rov qab los kaw cov khoom tom qab thiab tiv thaiv kev sib pauv ntawm cov dej noo ntawm cov khoom thiab ib puag ncig. Txoj kev no yog tus nqi pheej yig, tab sis cov khoom lag luam zoo ruaj khov, tsis muaj kev hloov pauv tseem ceeb hauv cov dej noo los ntawm kev hloov pauv hauv qhov chaw cia khoom. Cov khoom zoo yog ruaj khov thiab lub tshuab adaptability zoo.

03/ Ntxiv cov txheej txheem embossing

Thaum lub sij hawm tsim khoom thiab kev loj hlob, tshwj tsis yog tias tau teev tseg, cov txheej txheem embossing yuav tsum tau siv thaum twg los tau los hloov cov khoom ntawm lub cev fibers hauv zos thiab txo cov khoom shrinkage tus nqi. Cov duab embossing feem ntau suav nrog cov qauv mesh, cov qauv mesh + ntawv, thiab cov qauv. Tom qab cov khoom tau dhau los ua embossing, cov fibers sab hauv ntawm daim ntawv liner yog compressed thiab deformed, ua rau misalignment thiab rearrangement. Cov seem uas tau tsa ua ib lub phab ntsa mesh, thaum cov khoom seem ua ib lub mesh. Cov ceg tsa ceg ua haujlwm zoo li txhawb cov tav, ua kom lub zog thiab tiv thaiv cov khoom curling. Cov khoom ntawm lub cev kuj hloov raws li. Tom qab lub siab raug tshem tawm, cov compressed qhov chaw yog qhov nyuaj rau rov qab mus rau lawv cov qub lub xeev, zoo heev txo deformation, txhim kho shaping, txo curling hnyav, thiab xyuas kom meej ruaj khov khoom siv.

Embossing muaj cov nqi tsim khoom tsawg, cov khoom lag luam ruaj khov, cuam tshuam tsawg heev los ntawm ib puag ncig kub thiab av noo, thiab siv dav; tshaj 95% ntawm cov ntaub ntawv hauv ob sab phlu siv cov txheej txheem no.

04/ Txo qhov nro slitting

Thaum slitting daim ntawv liner, winding nro ntawm daim ntawv liner nce, ua rau cov txhuas ntawv ci txheej, number case txheej, nplaum txheej, thiab liner txheej yuav stretched ib txhij. Thaum cov txheej txheem rov qab yog ncab, cov fibers elongate thiab ua thinner, poob tensile lub zog, cov fibers shrink longitudinally, thiab cov ntawv thaub qab rov qab mus rau nws cov duab qub. Aluminium ntawv ci txheej lengthens thiab thins nyob rau hauv stretching, muab cov txhuas ntawv ci ductility; Tom qab poob lub zog tensile, cov ntawv ci tseem nyob hauv nws qhov qub.

Cov ntawv hauv ob sab phlu yog siv hauv cov tshuab luam yeeb, feem ntau txiav txhua txhua 125 hli. Kev txiav tuaj yeem suav hais tias yog txheej txheem ntawm kev poob nro: thaum cov ntawv hauv ob sab phlu poob nws qhov nro, cov ntaub ntawv hauv ob sab hauv shrinks longitudinally, aluminium ntawv tseem tsis hloov, thiab cov ntawv hauv ob sab phlu curls rau ntawm daim ntawv. Yog li ntawd, txo slitting nro tuaj yeem tswj tau qhov curling ntawm daim ntawv hauv ob sab phlu.

05/ Siv cov ntim ntim ntim

Ntim rau hauv lub hnab ntim, npaj siv tam sim ntawd. Yog tias tsis siv tam sim ntawd, nws tseem yuav tsum tau muab kaw thiab khaws cia, ua kom cov khoom siv sij hawm sib cuag nrog huab cua, txo qhov kev sib pauv ntawm cov ntaub ntawv hauv ob sab phlu thiab noo noo hauv huab cua, thiab txo qis curling ntawm daim ntawv liner. Txoj kev no txo ​​qis cov nqi tsim khoom tab sis yuav tsum muaj kev tswj hwm nruj ntawm cov txheej txheem tsim khoom kom ntseeg tau tias cov khoom tiaj tus thiab tsis curled ua ntej ntim khoom . ...
