PET daim ntawv ntau lawm kab yog ib hom khoom siv los ua PET (polyethylene terephthalate) nplooj ntawv. PET daim ntawv yog siab - cov ntaub ntawv yas ua tau zoo paub txog nws cov pob tshab zoo heev thiab lub zog txhua yam. Nws yog dav siv hauv kev lag luam xws li ntim khoom noj, khoom siv kho mob, thiab cov khoom siv hluav taws xob.
Cov kab ntawv PET feem ntau muaj cov khoom siv raw khoom, extruder, yaj lim, extrusion tuag, peb - yob calender, cua txias system, txiav tshuab, thiab stacking tshuab. Tag nrho cov txheej txheem tsim muaj xws li raw khoom conveying, extrusion, txias, calendering, txiav, thiab stacking.
Ua ntej, PET raw cov ntaub ntawv yog pub rau hauv extruder los ntawm cov khoom siv raw khoom siv. Lub extruder heats PET raw cov ntaub ntawv thiab extrudes lawv los ntawm ib tug ntsia hlau, ua ib tug nruam yaj. Cov yaj dhau los ntawm cov lim dej kom tshem tawm cov impurities thiab nkag mus rau hauv extrusion tuag.
Lub extrusion tuag yog ib qho ntawm cov khoom tseem ceeb hauv PET daim ntawv ntau lawm kab. Nws tsim thiab kev tsim khoom ncaj qha cuam tshuam rau qhov zoo thiab kev ua haujlwm ntawm daim ntawv. Los ntawm kev kho cov qauv thiab qhov ntev ntawm qhov tuag, cov nplooj ntawv PET ntawm cov thicknesses sib txawv, qhov dav, thiab cov duab tuaj yeem tsim tau. Lub tshuab cua txias hauv extrusion tuag zoo tswj qhov kub ntawm daim ntawv, ua kom nws zoo.
Lub yaj tawm ntawm qhov extrusion tuag yog pub rau peb -roll calender. Peb -roll calender yog ib qho tseem ceeb ntawm cov khoom siv rau calendering lub yaj mus rau hauv nyias nyias. Nws muaj peb lub voj voog sib luag, thiab los ntawm kev kho qhov sib nrug thiab kev sib hloov ceev ntawm cov chais, lub thickness thiab smoothness ntawm daim ntawv tuaj yeem tswj tau. Thaum lub sij hawm calendering txheej txheem, daim ntawv yog ceev ceev los ntawm cov cua txias system kom solidify nws thiab tswj cov yam xav tau.
Daim ntawv calendered PET raug xa mus rau lub tshuab txiav. Lub tshuab txiav txiav cov ntawv rau hauv qhov yuav tsum tau ua raws li preset ntev thiab dav. Los ntawm kev kho cov hniav thiab kev tswj xyuas qhov tseeb, lub tshuab txiav ua tiav siab - precision txiav.
Thaum kawg, cov ntawv txiav PET raug muab tso rau hauv lub tshuab stacking. Lub tshuab stacking stacks cov nplooj ntawv ua ke thiab pob los yog cim lawv raws li xav tau. Nws tuaj yeem hloov kho raws li cov kab ntau lawm ceev thiab daim ntawv qhov ntev, txhim kho kev tsim khoom thiab cov khoom zoo.
Hauv cov ntsiab lus, PET daim ntawv ntau lawm kab yog cov khoom siv tau zoo, ruaj khov, thiab txhim khu kev qha uas ua tau raws li qhov xav tau ntawm cov ntawv PET thoob plaws ntau qhov kev lag luam. Nrog kev nce qib hauv kev siv thev naus laus zis thiab nce kev lag luam xav tau rau siab - cov ntaub ntawv yas ua tau zoo, PET cov kab ntau lawm yuav ua lub luag haujlwm tseem ceeb hauv kev txhim kho yav tom ntej.
