Nrhiav kom zoo dua koj cov kab ntim khoom lossis txhim kho kev ua haujlwm ntawm cov qauv laminated? Cov lus qhia siv tau no tshawb txog cov hauv paus ntsiab lus tseem ceeb, xaiv cov khoom siv, cov txheej txheem ua, thiab cov txheej txheem daws teeb meem hauv txheej txheej extrusion (tseem hu ua lamination) - cov cuab yeej siv dav hauv ntim khoom, kho mob, tsheb, thiab kev lag luam.

Dab tsi yog Lamination (Extrusion Txheej) thiab Nws Ua Haujlwm Li Cas?

Lamination, los yog extrusion txheej, yog txheej txheem uas muaj cov txheej txheem molten yas (feem ntau polyethylene, PE) uniformly rau substrates xws li ntawv, ntaub, non-wovens, los yog txhuas ntawv ci. Siv cov khoom siv extrusion, cov yas yog melted, coated, thiab txias los tsim cov qauv sib xyaw.

Lub hauv paus ntsiab lus tseem ceeb yog siv cov fluidity ntawm molten yas ntawm qhov kub thiab txias kom ua tiav kev sib khi nruj nrog cov substrate, yog li ntxiv cov khoom thaiv, kub-sealability, thiab durability rau cov khoom siv hauv paus.

Cov txheej txheem Lamination tseem ceeb

1. Raw Material Preparation: Xaiv cov yas pellets uas tsim nyog (piv txwv li, PE, PP, PLA) thiab substrates (piv txwv li, daim ntawv nkauj xwb, cov ntaub tsis-woven).

2. Yas Melting thiab Extrusion: Yas pellets yog pub rau hauv ib qho extruder, uas lawv melted rau hauv cov kua dej khov ntawm qhov kub thiab txias. Cov yas molten yog tom qab ntawd extruded los ntawm T-tuag los ua ib qho yeeb yaj kiab zoo li yaj.

3. Txheej thiab Compounding: Lub molten yas zaj duab xis yog precisely coated rau saum npoo ntawm pre-unwound substrate nyob rau hauv nruj tswj. Nyob rau ntawm txheej txheej, cov yas molten thiab cov substrate yog nruj nreem khi ua ke nyob rau hauv qhov kev txiav txim ntawm lub siab rollers.

4. Kev ua kom txias thiab teeb tsa: Cov khoom sib xyaw ua ke sai dhau los ntawm cov cua txias, tso cai rau cov txheej txheem yas molten kom txias thiab khov sai, ua kom muaj zog yas zaj duab xis.

5. Winding: Cov khoom txias thiab teeb laminated composite yog qhov txhab rau hauv cov yob rau kev ua haujlwm tom ntej thiab siv.

6. Cov kauj ruam xaiv tau: Qee qhov xwm txheej, txhawm rau txhim kho qhov adhesion ntawm laminated txheej lossis txhim kho cov khoom nto, lub substrate yuav raug kho corona ua ntej txheej.

PBS / PBAT: hloov tau thiab ua tau zoo; haum rau cov kev daws teeb meem ntim ruaj khov.

• Tshwj xeeb Polymers

EVOH: Cov pa oxygen zoo heev, feem ntau siv los ua txheej nruab nrab hauv ntim khoom noj.

Ionomers: siab clarity, roj kuj, zoo sealability.

Cov teeb meem thiab kev daws teeb meem hauv Extrusion Txheej thiab Lamination:Phau Ntawv Qhia Txog Kev Teeb Meem

1. Adhesion / Thaiv cov teeb meem

Ua rau: Tsis txaus cua txias, muaj zog winding ntau dhau, tsis txaus los yog tsis sib xws ntawm cov neeg ua haujlwm tiv thaiv thaiv, kub ambient kub, thiab av noo.

Kev daws: Txo cov cua txias rau cov menyuam kub, ua kom lub sijhawm txias; tsim nyog txo winding nro; nce los yog optimize tus nqi thiab dispersion ntawm anti-blocking agents (xws li, erucamide, oleamide, silica, SILlKE SILIMER series super slip thiab anti-blocking masterbatch); txhim kho ambient kub thiab av noo nyob rau hauv qhov chaw tsim khoom.
