Cov Ntawv Thov
Ntim: Cov khoom siv hluav taws xob (xov tooj, pob ntseg), cov khoom ua si, khoom noj khoom haus, ua haujlwm noj tshuaj, FDA raws li chocolates).
Khw muag khoom & tshaj tawm: Cov khw muag khoom, cov thawv kom hniav zoo nkauj, khoom plig cov khoom plig.
Yam muaj hauj lwm: Anti-zoo nkauj cov tais rau precision Cheebtsam (ESD tiv thaiv).Cov txheej txheem tsim khoom
Cov Ntawv Ntau Lawm:
Ntau tus pulping → ob chav txheej → supending supendering → sluting (flatness tsawg dua los yog sib npaug ntawm 2 hli / m).
Ntxeev myias:
Lub tuam txhab: Kev cai pwm (thev taus ± 0.1mm).
Thermoforming:
Cua sov (PVC: 140-160 degree; Tsiaj: 180-220 Degree) → Nqus Plua Plav Ua → Lub nqus khoom →
Lamination: Saib ncaj qha thermal khi ntawm cov yeeb yaj kiab yas (piv txwv li, ua ntej-coated tsiaj).
Kev Ua Haujlwm Tom Qab:
Tuag-txiav → Tej Kev Kho Cov npoo npoo av (Matte, Kub Stamping, UV GLAYING) → QC (Qhov ntev, cov xim sib tw, xim raug).Xaiv & Siv Cov Lus Qhia Siv
Cov ntsiab lus tseem ceeb:
Lub hauv paus hnyav: 250-350 g / ㎡ (sib npaug ntawm formability thiab rigidity).
Folding cov nyiaj cheb: Ntau dua los yog sib npaug rau 100 lub voj voog (tiv thaiv cais tawm).
Nto roughness: tsawg dua los yog sib luag rau 10μm (ua kom pom tseeb ntse luam ntawv).
Ntawv muaj:
Ntawv: FSC, PEFC (muaj kev cia siab).
YAS: FDA (Hu Rau Cov Zauv Khoom Noj), ROHS (kev phom sij-dawb).
Cov tshev nyiaj ntau:
Lub tshuab kom haum rau lub tshuab: Ua kom cov ntawv tuab ntais ntawv hlwv hlwv tshuab muaj peev xwm (piv txwv li, 300g ntawv yuav tsum muaj ntau dua los yog 50T lub siab).
Kev kuaj ua ntej ntau lawm: Siv tau kav dej nplaum (3m daim kab xev).
Chaw ntim khoom:
Yoov tswj (tsawg dua los yog sib npaug rau 60% Rh), UV kev tiv thaiv, tiaj tus kheej (tiv thaiv curling).Cov teeb meem ntau yam & kev daws teeb meem
| Tsab | Kev kom | Lus teb |
|---|---|---|
| Blister tawg | High paper moisture (>8%) | Ua ntej-qhuav rau 6-7% cov ntsiab lus noo noo. |
| Sau Delamination | Cov txheej txheem tsis zoo adhesion | Thov PVA primer rau kev kho kom nto. |
| Cavity deformation | Uneven puab qhov kub | Optimize cua sov / cua txias. |
| Tsis kaj tsw tsw | Rov ua dua tshiab / tsis zoo yas yas | Siv cov khoom noj-qib (SGS-ntawv pov thawj). |
Cov Qauv Kev Lag Luam & Tiam
Tus qauv: ASTM D6491 (Ntim Daim Ntawv Ntawv Khoom), ISO 186 (ruaj khov sab ruaj khov).
Kev Ncaj Ncees Ncaj Ncees:
Kev hloov pauv Bio: Pla (polylactic acid) hlwv hloov PVC.
Kev lag luam raws li: Cov kev sib xyaw ua ke sau ua ke (piv txwv li, ntawv-ntawv Laminates nrog sib cais tshuab).Cov piv txwv tiag tiag
Ib 300g / ㎡ Pos-blistered dawb board ntawv rau cov ntim smartphone ntim khoom lag luam:
Yam: FDA-raws cai, FSC-ntawv pov thawj ntawv + 0.3 hli tsiaj cov txheej.
Kev ua: 220 Degree Thermoforming → UV-glossed tiav lawm → tuag-txiav kom haum tus xov tooj contours.
Ua yeeb yam: Cov tais raj nrog cov khoom siv anti-zoo li qub, cov kev daws teeb meem siab hom duab, thiab tsim qauv kho tshiab.
Yog tias koj xav tau ob npaug ib sab nplej luam ntawv luam ntawv rau lub tshuab nqus tsev ua tiav, koj tuaj yeem tiv tauj peb rau kev hais.
