Abstract: Yog tias koj xav ua cov txheej txheem sib xyaw uas tsis muaj kuab tshuaj siv tas li, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov nplaum sib xyaw kom raug. Tsab xov xwm no qhia txog yuav ua li cas xaiv cov nplaum sib xyaw uas tsis muaj kuab tshuaj zoo tshaj plaws rau cov khoom sib xyaw thiab cov qauv.
Nrog rau kev loj hlob thiab kev nrov ntawm cov thev naus laus zis sib xyaw ua ke uas tsis muaj kuab tshuaj, ntau thiab ntau cov khoom siv zaj duab xis nyias tuaj yeem siv rau cov khoom sib xyaw ua ke uas tsis muaj kuab tshuaj. Yuav kom siv cov thev naus laus zis sib xyaw ua ke uas tsis muaj kuab tshuaj kom ruaj khov, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov nplaum sib xyaw kom raug. Hauv qab no, raws li tus sau ntawv qhov kev paub dhau los, peb yuav qhia txog yuav ua li cas xaiv cov nplaum uas tsis muaj kuab tshuaj kom haum.
Tam sim no, kev lamination qhuav thiab kev lamination tsis muaj kuab tshuaj sib koom ua ke. Yog li ntawd, txhawm rau kom ruaj khov kev siv cov thev naus laus zis lamination tsis muaj kuab tshuaj, thawj qhov yog kom nkag siab tag nrho cov qauv khoom ntawm lub Hoobkas ntim khoom, faib cov qauv khoom kom meej, faib cov qauv khoom uas tuaj yeem siv rau kev lamination tsis muaj kuab tshuaj, thiab tom qab ntawd xaiv cov nplaum tsis muaj kuab tshuaj uas tsim nyog. Yog li, yuav ua li cas thiaj xaiv tau cov nplaum tsis muaj kuab tshuaj zoo? Sib phim ib qho los ntawm ib qho los ntawm cov hauv qab no.
- lub zog nplaum
Vim yog qhov nyuaj thiab ntau yam ntawm cov ntaub ntawv ntim khoom, kev kho qhov chaw ntawm cov substrates kuj sib txawv heev. Cov ntaub ntawv ntim khoom yooj ywm feem ntau kuj muaj cov yam ntxwv sib txawv, xws li PE, BOPP, PET, PA, CPP, VMPET, VMCPP, thiab lwm yam. Kuj tseem muaj qee cov ntaub ntawv uas tsis tshua siv rau hauv cov khoom ntim yooj ywm, xws li PS, PVC, EVA, PT, PC, ntawv, thiab lwm yam. Yog li ntawd, cov nplaum tsis muaj kuab tshuaj uas cov tuam txhab xaiv yuav tsum muaj kev nplaum zoo rau feem ntau cov ntaub ntawv ntim yooj ywm.
- Kev tiv thaiv kub
Kev tiv taus kub muaj ob yam. Ib qho yog kev tiv taus kub siab. Tam sim no, ntau yam khoom noj yuav tsum tau ua kom huv si thaum kub siab, qee yam raug ntxuav kom huv si ntawm 80-100° C, thaum lwm tus raug sterilized ntawm 100-135° C. Lub sijhawm ua kom huv si sib txawv, qee qhov yuav tsum tau siv sijhawm 10-20 feeb thiab lwm qhov yuav tsum tau siv sijhawm 40 feeb. Qee qhov tseem raug ua kom huv si nrog ethylene oxide. Cov ntaub ntawv sib txawv muaj cov txheej txheem ua kom huv si sib txawv. Tab sis cov nplaum uas tsis muaj kuab tshuaj xaiv yuav tsum ua tau raws li cov kev xav tau kub siab no. Lub hnab tsis tuaj yeem ua kom qhuav lossis puas tom qab kub siab. Tsis tas li ntawd, cov khoom kho nrog cov nplaum uas tsis muaj kuab tshuaj yuav tsum muaj peev xwm tiv taus kub siab ntawm 200° C los yog txawm tias 350° C tam sim ntawd. Yog tias qhov no ua tsis tau, lub hnab kub kaw yuav yooj yim tawg.
Qhov thib ob yog qhov tsis kam rau qhov kub thiab txias, uas tseem hu ua kev tiv thaiv khov. Ntau cov ntaub ntawv ntim khoom mos muaj cov khoom noj khov, uas xav tau cov nplaum tsis muaj kuab tshuaj kom tiv taus qhov kub thiab txias qis. Thaum qhov kub qis, cov ntaub ntawv khov los ntawm cov nplaum lawv tus kheej yuav ua rau tawv, tawg, tawg, thiab tawg. Yog tias cov xwm txheej no tshwm sim, nws qhia tau tias cov nplaum xaiv tsis tuaj yeem tiv taus qhov kub thiab txias qis.
Yog li ntawd, thaum xaiv cov nplaum uas tsis muaj kuab tshuaj, kev nkag siab thiab kev sim kom ntxaws txog kev tiv taus kub yog qhov tsim nyog.
3. Kev Noj Qab Haus Huv thiab Kev Nyab Xeeb
Cov nplaum uas tsis muaj kuab tshuaj siv rau hauv cov khoom noj thiab tshuaj ntim yuav tsum muaj kev tu cev zoo thiab kev nyab xeeb. Muaj cov cai nruj heev hauv ntau lub tebchaws thoob ntiaj teb. US FDA faib cov nplaum uas siv rau hauv cov khoom ntim khoom sib xyaw rau cov khoom noj thiab tshuaj ua cov khoom ntxiv, txwv cov khoom siv raw siv los tsim cov nplaum thiab txwv tsis pub siv cov tshuaj uas tsis suav nrog hauv cov npe khoom siv raw, Thiab cov khoom sib xyaw ua ke tsim nrog cov nplaum no raug cais thiab txwv hauv lawv qhov kub thiab txias, suav nrog kev siv chav tsev kub, kev siv tshuaj tua kab mob kub npau, kev siv tshuaj tua kab mob kub 122 ° C, lossis kev siv tshuaj tua kab mob kub siab 135 ° C thiab siab dua. Tib lub sijhawm, cov khoom tshuaj xyuas, cov txheej txheem sim, thiab cov cim qhia kev siv rau cov khoom ntim kuj tau tsim. Kuj tseem muaj cov kev cai thiab kev txwv hauv Suav teb tus qauv GB9685. Yog li ntawd, cov nplaum uas tsis muaj kuab tshuaj siv rau cov khoom lag luam xa tawm txawv teb chaws yuav tsum ua raws li cov cai hauv zos.
4. Ua kom tau raws li qhov xav tau ntawm cov ntawv thov tshwj xeeb
Kev siv cov khoom sib xyaw ua ke uas tsis muaj kuab tshuaj hauv kev ntim khoom yooj ywm tau txhawb nqa lawv txoj kev nthuav dav mus rau lwm qhov chaw. Tam sim no, muaj cov chaw tshwj xeeb uas lawv tau siv:
4.1 Cov ntawv ntim khoom PET sib xyaw uas tsis muaj kuab tshuaj
Cov ntawv PET feem ntau yog ua los ntawm cov ntaub ntawv PET nrog lub thickness ntawm 0.4 hli lossis ntau dua. Vim yog lub thickness thiab rigidity ntawm cov khoom siv no, nws yog ib qho tsim nyog los xaiv cov nplaum tsis muaj kuab tshuaj nrog cov nplaum pib siab thiab viscosity los ua cov khoom siv no. Cov khoom tiav ua los ntawm cov khoom sib xyaw no feem ntau yuav tsum tau ua rau ntau yam duab, qee qhov uas xav tau stamping, yog li qhov yuav tsum tau ua rau lub zog tev kuj tseem siab. WD8966 tsim los ntawm Kangda Cov Khoom Tshiab muaj qhov pib siab thiab stamping tsis kam, thiab tau ua tiav siv rau hauv PET daim ntawv sib xyaw.
4.2 Cov ntaub ntim khoom tsis-woven uas tsis muaj kuab tshuaj
Cov ntaub tsis yog woven yog siv dav thiab muaj ntau hom. Daim ntawv thov ntawm cov ntaub tsis yog woven hauv qhov chaw tsis muaj kuab tshuaj feem ntau nyob ntawm qhov tuab ntawm cov ntaub tsis yog woven thiab qhov ceev ntawm cov fibers. Hais lus piv txwv, qhov denser ntawm cov ntaub tsis yog woven, qhov zoo dua cov tshuaj tsis muaj kuab tshuaj. Tam sim no, ib qho khoom polyurethane kub yaj nplaum feem ntau yog siv rau cov ntaub tsis yog woven uas tsis muaj kuab tshuaj.
