Raws li lub teb chaws dhau los ua ntau dua thiab ntau nruj nrogKev tiv thaiv ib puag ncig kev tswj hwm, kawg cov neeg tau txais kev pab txoj kev caum qab ntawm kev ua neeg zoo tag nrho, kev pom kev thiabntsuab ib puag ncigKev tiv thaiv ntawm cov khoom ntim ntim ntawm ntau hom khoom tau qhia ntau hom tswv lag luam ntxiv cov ntawv sau rau cov ntawv tsim qauv. Xws li tus kws sau ntawv nws tus kheej, Kuv kuj nyiam ntawv ntim ntau heev, thiab kuv feem ntau sau qee lub hnab ntim khoom ntawm hom no. Peb lub tuam txhab cov khoom tiav tiav kuj yog qhov zoo heev, xws li aCOFFEE KRAFT Ntawv Zipper Hnab Nrog Air ValveTias peb nyuam qhuav ua tsis ntev los no.
Tus tsim qauv ntawm cov ntawv yas ntim yog cov khoom tshiab thiab cim, uas tau coj kev ua tau zoo tshaj plaws rau cov tswv. Txawm li cas los xij, nyob rau hauv cov txheej txheem ntau lawm ,,, cov txheej txheem sib xyaw ua ke suav nrog cov tshuaj yeeb dej caw, thiab lwm yam yuav ua rau muaj ntau cov khib nyiab, thiab lwm yam khoom seem, thiab lwm yam. Teeb meem xws li tshav kub thiab tawg. Txhawm rau txhim kho qhov zoo ntawm cov ntawv yas ntim yas ntim, nws yog qhov tsim nyog los pib nrog kev nkag siab tob, txhawm rau ua tiav ob zaug tshwm sim nrog ib nrab ntawm lub dag zog.
1. Cov xwm txheej tam sim no ntawm cov ntawv yas ntim
Nyob rau hauv cov nqe lus ntawm cov qauv, muaj ntau yam qauv ntawm cov qauv khoom ntawm kev ua lag luam, feem ntau muab faib rau hauv opp // pap, pap, pap, pap, pap, pum // al, etc. los ntawm kev faib tawm ntawm daim ntawv: txhua hom xaiv sib txawv hom ntawv, cov tuab tuab thiab hnyav ntawm daim ntawv yog txawv, xws li 20 txog 100g. Cov txheej txheem ntau lawm suav nrogExtrusion Compounding, qhuav compounding, hnyav-dawb compounding, thiab lwm yam.
Los ntawm cov kev sib piv saum toj no, txhua tus txheej txheem muaj qhov zoo thiab qhov tsis zoo. Hauv cov ntsiab lus yooj yim, cov kuab tshuaj dawb muaj qhov zoo, xws li muaj nuj nqis, peb tseem pom zoo kom qhuav (xyuam xim rau cov ntawv xaiv, kua nplaum , thiab lwm yam).
2. Kev xaiv cov ntaub ntawv
Muaj ntau hom ntawv cov ntaub ntawv uas tuaj yeem siv rau cov ntawv yas sib xyaw, xws li ntawv nplaum, sau ntawv, cov ntawv nplaum, cov ntaub ntawv ntaub, cov ntawv mos mos, lub hauv paus ntawv, thiab lwm yam. Thiab raws li cov qauv tsim ntim cov qauv, xws li OPP / ntawv, PEX, CP // ntawv, al // ntawv, lwm yam.
Muaj txog ntau yam kev faib tawm raws li kev siv sib txawv ntawm cov ntawv sau, thiab lwm yam., BEML daim ntawv, thiab lwm yam los ntawm 25GSM rau 80gsm. Vim muaj ntau daim ntawv thiab cov ntsiab lus sib txawv, cov ntsiab lus hauv qab no yuav tsum tau them sai sai thaum siv cov ntawv sib txawv:
① - Feem ntau hais lus, txoj kev sib luag ntawm daim ntawv yog qhov sib txuas nrog cov yeeb yaj kiab, thaum lub ntsej muag tawv thiab zaj duab xis nyuaj rau kev sib khi. Qhov no yog feem ntau yog vim yog lub pits thiab pits ntawm sab tawv. Nplaum ua rau lub qhov.
②PAY XIM RAU COV NTAWV CEEV. Cov fibers ntawm qee cov ntawv yog xoob heev. Txawm hais tias daim ntawv thiab zaj duab xis tau cog lus zoo thaum lawv tau laminated, lawv nquag mus rau delamination tom qab sib tw so.
③ Cov ntsiab lus noo noo ntawm daim ntawv kuj muaj qee yam cuam tshuam rau cov nyhuv uas ua tau zoo. Raws li tus kheej kev paub dhau los, cov ntsiab lus noo ntawm cov ntawv feem ntau tsis tshaj 0.4%. Nws yog lub tswv yim zoo kom tawm ntawm daim ntawv hauv qhov cub rau 1 txog 2 hnub ua ntej ntau lawm
Ua tib zoo saib kom huv ntawm daim ntawv saum npoo av.
3. Tsim Qauv Tsim
Thaum tsim qauv ntawm cov qauv ntawm daim ntawv ntim cov ntaub ntawv ntim, nws yog qhov tsim nyog kom nkag siab cov khoom ntawm kev ntim khoom thiab xaiv cov khoom tsim nyog thiab cov qauv.
Nyob rau hauv cov nqe lus ntawm lub hnab qauv, nws yog feem ntau siv rau cov khoom lag luam ntim khoom, thiab cov duab yog mos. Xav txog cov ntim muaj nuj nqi thiab cov khoom lag luam yuav tsum tau muab faib ua peb hom: tsis muaj qhov rai ntaus, lub qhov rai hom tshwj xeeb.
Lub hnab uas siv hluav taws xob yog cov qauv hauv ib lub hnab. Lub cev tseem ceeb yog cov ntawv sau (xws li Kraft ntawv), thiab cov txheej txheem yas ntxiv), uas tuaj yeem thaiv cov tshuaj ntsuab, thiab pypeCenively los tiv thaiv cov ntsiab lus cov khoom siv tsis xwm yeem , thiab cov txheej txheem moulding yog ib qho zoo ib yam li ntawm ntim yas hloov tau. Ua ntej, cov ntawv yog ua ke nrog cov yeeb yaj kiab yas thiab tom qab ntawd muab cov hnab yas ua kom lub hnab;
Lub Sawb Qhov rai lub hnab thiab lub qhov rais tshwj xeeb yog ntawm lub hnab teeb tsa lub hnab, thiab daim ntawv yog siv los ua ib nrab huab cua qhov, kom lub ntim khoom tuaj yeem nthuav tawm ntau yam. Ntxiv rau kev tswj hwm lub pob tshab ntawm lub hnab ntim khoom, nws kuj tuaj yeem muaj cov ntawv nyeem. Lub qhov rai lub hnab tsim txoj kev yog los ua ke nqaim-zaj duab xis yas thiab ob nplooj ntawv nrog lwm cov yeeb yaj kiab yas. Muaj ob txoj hauv kev los ua kom muaj qhov rais tshwj xeeb. Ib qho yog qhib lub qhov rai hauv cov ntawv sau ua ntej kom ua cov duab sib txawv, thiab tom qab ntawd compound cov khoom. Cov khoom siv ntawm cov ntawv sib xyaw no kuj tseem tuaj yeem hloov pauv thiab tsim hauv thaj chaw loj los txhim kho qhov yooj ntawm cov txheej txheem ntau lawm.
4. Cov Txheej Txheem Ntau Lawm
Cov txheej txheem sib xyaw ua kom qhuav yog cov ua kom paub tab. Cov lag luam xaiv cov kuab tshuaj-raws li cov kua nplaum, thiab tseem xaiv cov kua nplaum thiab kua dej tiv thaiv dej. Ntawm no peb hais tias tsis hais yam dab tsi kua nplaum siv, cov ntsiab lus hauv qab no yuav tsum tau them siab rau:
a. Qhov kev xaiv ntawm daim ntawv tseem ceeb heev;
b. Dej cov ntsiab lus tswj cov ntawv;
c, ntawv glossy thiab matte xaiv;
d. Them sai sai rau kev nyiam huv ntawm daim ntawv;
e, tswj cov nyiaj ntawm cov kua nplaum;
f. Kev tswj ceev kom tiv thaiv cov kuab khoom seem ntawm kev ua siab dhau.
