Raws li lub teb chaws yuav ntau thiab ntau nruj nrogkev tswj hwm kev tiv thaiv ib puag ncig, kawg cov neeg siv khoom 'nrhiav qhov zoo tshaj plaws, pom kev cuam tshuam thiabntsuab ib puag ncigkev tiv thaiv ntawm cov khoom ntim ntawm ntau lub npe tau ua rau ntau tus tswv lag luam ntxiv cov khoom ntawm cov ntawv rau kev ntim khoom.Nrog rau tus editor nws tus kheej, kuv kuj nyiam cov ntawv ntim ntau heev, thiab kuv feem ntau sau qee lub hnab ntim khoom ntawm hom no.Peb lub tuam txhab cov khoom tiav kuj tseem zoo heev, xws li akas fes kraft ntawv zipper hnab nrog cua valveuas peb nyuam qhuav ua tsis ntev los no.
Kev tsim cov ntawv ntim cov ntawv yas sib xyaw yog qhov tshiab thiab tshwj xeeb, uas tau coj cov txiaj ntsig zoo tshaj plaws rau cov tswv lag luam.Txawm li cas los xij, hauv cov txheej txheem tsim khoom, cov txheej txheem sib xyaw siv suav nrog cov khoom sib xyaw qhuav, extrusion composite, hnyav-dawb composite, thiab lwm yam, uas kuj ua rau qee cov txheej txheem tsis ruaj khov, xws li ntau cov khoom pov tseg, tsw, cov kuab tshuaj ntau, thiab lwm yam. Teeb meem xws li kub sealing thiab blistering.Txhawm rau txhim kho qhov zoo ntawm cov ntaub ntawv-yas sib xyaw ntim, nws yog ib qho tsim nyog yuav tsum pib nrog cov txheej txheem raws li kev nkag siab tob ntawm hom ntim no, txhawm rau ua tiav ob zaug qhov txiaj ntsig nrog ib nrab ntawm kev siv zog.
1. Cov xwm txheej tam sim no ntawm cov ntawv ntim khoom yas sib xyaw
Hais txog cov qauv, muaj ntau hom ntawv-yas qauv cov khoom lag luam, feem ntau muab faib ua OPP / / PAP, PET / / PAP, PAP / / CPP (PE), PAP // AL, thiab lwm yam. Los ntawm kev faib tawm ntawm daim ntawv: txhua lub npe xaiv cov ntawv sib txawv, qhov tuab thiab qhov hnyav ntawm daim ntawv sib txawv, xws li 20 txog 100g.Cov txheej txheem ntau lawm suav nrogextrusion compounding, qhuav compounding, hnyav-dawb compounding, lwm.
Los ntawm kev sib piv saum toj no, txhua tus txheej txheem muaj qhov zoo thiab qhov tsis zoo.Hauv cov ntsiab lus yooj yim, cov khoom tsis muaj kuab tshuaj muaj qhov zoo hauv kev ua tau zoo, xws li kev ua haujlwm, kev poob, thiab lwm yam. Yog tias qhov kev txiav txim kom muaj nuj nqis tsawg thiab qhov kev txiav txim nyuaj, peb tseem pom zoo kom qhuav compounding (ua tib zoo xaiv cov ntawv, kua nplaum. , thiab lwm yam).
2. Kev xaiv cov khoom siv
Muaj ntau ntau hom ntawv uas tuaj yeem siv rau cov ntaub ntawv-yas sib xyaw, nrog rau cov ntawv coated, ntawv dawb kraft ntawv, ntawv daj kraft ntawv, ob-nplaum ntawv, ntawv sau ntawv, ntawv teeb-coated, pearl ntawv, ntawv mos ntawv, Cov ntawv hauv paus, thiab lwm yam, thiab raws li kev tsim qauv tsim, tuaj yeem ua rau cov khoom sib txawv, xws li OPP / ntawv, PET / ntawv, CPP / / ntawv, PE / / ntawv, AL / / ntawv, thiab lwm yam.
Muaj txog kaum ob ntawm kev faib tawm raws li kev siv sib txawv, txheej txheem, thiab lwm yam, feem ntau siv hauv kev ntim khoom yooj yim yog cov ntawv kraft, ntawv dawb kraft, ntawv paj rwb mos, ntawv hauv paus, ntawv hlaws, thiab lwm yam, qhov ntau ntawm 25gsm ua 80gsm.Vim muaj ntau hom ntawv thiab siv sib txawv, cov ntsiab lus hauv qab no yuav tsum tau them sai sai rau thaum siv cov ntawv sib txawv:
① - Feem ntau hais lus, sab du ntawm daim ntawv yog yooj yim dua rau kev sib raug zoo nrog zaj duab xis, thaum sab ntxhib thiab zaj duab xis nyuaj rau kev sib raug zoo.Qhov no feem ntau yog vim cov pits thiab pits ntawm sab ntxhib.Adhesive ua rau lub qhov.
② Ua tib zoo saib cov ntawv ceev.Cov fibers ntawm qee cov ntawv yog xoob heev.Txawm hais tias daim ntawv thiab zaj duab xis zoo sib koom ua ke thaum lawv laminated, lawv muaj feem cuam tshuam rau delamination tom qab cua sov sealing.
③ Cov dej noo ntawm daim ntawv kuj muaj qee yam cuam tshuam rau kev sib txuas lus.Raws li tus kheej kev paub, cov dej noo ntawm daim ntawv yuav tsum tsis pub tshaj 0.4%.Nws yog ib lub tswv yim zoo kom tso cov ntawv hauv qhov cub rau 1 mus rau 2 hnub ua ntej kev tsim khoom
④ Ua tib zoo saib xyuas qhov huv ntawm daim ntawv.
3. Tus qauv tsim
Thaum tsim cov qauv ntawm lub thawv ntim ntawv-yas, nws yuav tsum nkag siab txog cov khoom ntawm lub ntim thiab xaiv cov khoom tsim nyog thiab cov qauv.
Nyob rau hauv cov nqe lus ntawm lub hnab qauv, nws yog feem ntau yog siv rau cov khoom ntim khoom, thiab cov duab yog mos.Xav txog kev ntim khoom thiab cov khoom siv yuav tsum tau ua, cov qauv tuaj yeem muab faib ua peb hom: tsis muaj qhov rais hom, strip qhov rais hom thiab qhov rais tshwj xeeb-zoo li tus.
Lub hnab tsis muaj qhov rais yog lub hnab ntim ntau hom qauv.Lub cev tseem ceeb yog cov ntaub ntawv (xws li cov ntawv kraft), thiab cov txheej txheem sab hauv thiab sab nrauv feem ntau muaj kev tiv thaiv los ntawm cov yeeb yaj kiab yas xws li PE (polyethylene) thiab PP (polypropylene), uas tuaj yeem thaiv cov dej noo thiab oxygen kom tsis txhob muaj cov ntsiab lus ntawm cov khoom deteriorates. , thiab cov txheej txheem molding yog qhov tseem ceeb tib yam li cov yas ntim khoom yooj yim.Ua ntej, daim ntawv yog ua ke nrog cov yas zaj duab xis thiab tom qab ntawd kub-sau los ua lub hnab;
Lub hnab ntim lub qhov rais thiab qhov tshwj xeeb zoo li lub qhov rais yog ntawm lub qhov rais qauv lub hnab hom, thiab daim ntawv yog siv los ua ib feem ntawm cov pa qhov, kom lub ntim tuaj yeem nthuav qhia ntau yam.Ntxiv nrog rau kev tuav lub pob tshab ntawm lub hnab ntim khoom, nws tuaj yeem muaj cov ntawv zoo nkauj.Lub qhov rais lub hnab tsim txoj kev yog muab ib tug nqaim-dav yas zaj duab xis thiab ob nplooj ntawv ntawm daim ntawv nrog rau lwm qhov dav-dav yas zaj duab xis.Muaj ob txoj hauv kev los ua qhov tshwj xeeb zoo li lub qhov rais.Ib qho yog qhib lub qhov rais hauv cov ntaub ntawv ua ntej ua cov duab sib txawv, thiab tom qab ntawd muab cov khoom sib xyaw.Cov khoom siv ntawm cov txheej txheem sib xyaw kuj tuaj yeem hloov pauv thiab tsim nyob rau hauv thaj chaw loj los txhim kho qhov yooj yim ntawm cov txheej txheem ntau lawm.
4. Cov txheej txheem ntau lawm
Cov txheej txheem qhuav compounding yog tus paub tab.Cov lag luam xaiv cov kuab tshuaj raws li cov kua nplaum ob qho tib si, thiab tseem xaiv cov kua nplaum ib leeg thiab cov kua nplaum dej.Ntawm no peb xav tias txawm tias siv cov kua nplaum dab tsi, cov ntsiab lus hauv qab no yuav tsum tau them rau:
a.Kev xaiv ntawm daim ntawv tseem ceeb heev;
b.Kev tswj cov dej ntawm cov ntawv;
c, ntawv glossy thiab matte xaiv;
d.Ua tib zoo saib xyuas qhov huv ntawm daim ntawv;
e, tswj tus nqi ntawm cov kua nplaum;
f.Kev tswj ceev kom tsis txhob muaj kuab lom los ntawm qhov siab dhau.
