Daim ntawv PLA
PLA yog ib hom Aliphatic Polyesters uas zoo li kab. PLA siv tau rau hauv pob khoom tawv ntawm cov txiv hmab txiv ntoo, zaub, qe, zaub mov siav thiab zaub mov ci, kuj siv tau rau ntim cov sandwich, biscuit thiab qee cov pob khoom zoo li paj tshiab.
Kev piav qhia txog khoom
Polylactic acid (PLA) tuaj yeem lwj tag nrho mus rau hauv carbon dioxide thiab dej hauv qab ntuj tom qab pov tseg. Nws muaj kev tiv thaiv dej zoo, cov khoom siv kho tshuab, biocompatibility, tuaj yeem nqus tau los ntawm cov kab mob, thiab tsis muaj kuab paug rau ib puag ncig. Tib lub sijhawm, PLA kuj muaj cov khoom siv kho tshuab zoo. Nws muaj lub zog cuam tshuam siab, kev ywj pheej zoo thiab thermal stability, plasticity, processability, tsis muaj xim, permeability zoo rau oxygen thiab dej pa, thiab pob tshab zoo, tiv thaiv pwm, antibacterial, lub neej ua haujlwm yog 2 ~ 3 xyoos.
Qhov ntsuas kev ua tau zoo tshaj plaws ntawm cov ntaub ntawv ntim khoom yog huab cua permeability, thiab thaj chaw siv cov khoom no hauv ntim khoom tuaj yeem txiav txim siab raws li qhov sib txawv ntawm huab cua permeability ntawm cov ntaub ntawv. Qee cov ntaub ntawv ntim khoom xav tau oxygen permeability kom muab cov pa oxygen txaus rau cov khoom; qee cov ntaub ntawv ntim khoom xav tau ib qho thaiv rau oxygen hauv cov ntaub ntawv, xws li dej haus ntim khoom, uas xav tau cov ntaub ntawv uas tuaj yeem tiv thaiv oxygen nkag mus rau hauv pob khoom kom tiv thaiv pwm. Cov nyhuv ntawm kev loj hlob. PLA muaj roj thaiv, dej thaiv, pob tshab thiab luam tawm zoo.
PLA muaj qhov pom tseeb thiab ci ntsa iab zoo, thiab nws qhov kev ua tau zoo heev piv rau cellophane thiab PET, uas tsis muaj nyob rau hauv lwm cov yas uas lwj tau. Qhov pom tseeb thiab ci ntsa iab ntawm PLA yog 2 ~ 3 npaug ntawm cov zaj duab xis PP ib txwm thiab 10 npaug ntawm LDPE. Nws qhov pom tseeb siab ua rau qhov zoo li siv PLA ua cov khoom ntim khoom zoo nkauj. Piv txwv li, nws yog siv rau kev ntim khoom qab zib. Tam sim no, ntau lub ntim khoom qab zib hauv khw siv cov zaj duab xis ntim khoom PLA.
Cov tsos thiab kev ua tau zoo ntawm cov yeeb yaj kiab ntim khoom qab zib no zoo ib yam li cov yeeb yaj kiab ntim khoom qab zib ib txwm muaj, nrog rau kev pom tseeb siab, kev khaws cia zoo heev, kev luam tawm thiab lub zog, nrog rau cov khoom zoo heev, uas tuaj yeem khaws cov saj ntawm cov khoom qab zib zoo dua. Ib lub tuam txhab Nyij Pooj siv lub npe "racea" PLA ntawm American Cakir Dow Polymer Company ua cov khoom ntim rau cov khoom tshiab, thiab cov ntim khoom yog pob tshab heev. Toray Industries tau tsim cov yeeb yaj kiab ua haujlwm PLA thiab cov hlais siv nws cov thev naus laus zis nano-alloy. Cov yeeb yaj kiab no muaj tib lub cua sov thiab kev cuam tshuam tiv thaiv zoo li cov yeeb yaj kiab roj av, tab sis kuj muaj kev ywj pheej zoo heev thiab pob tshab.
PLA tuaj yeem ua rau cov khoom yas uas muaj pob tshab, cov khoom zoo thaiv, ua tau zoo heev thiab cov khoom siv kho tshuab, thiab siv tau rau kev ntim khoom ntawm cov txiv hmab txiv ntoo thiab zaub. Nws tuaj yeem tsim kom muaj chaw cia khoom zoo rau cov txiv hmab txiv ntoo thiab zaub, tswj cov haujlwm ntawm cov txiv hmab txiv ntoo thiab zaub, ncua kev laus, thiab tswj cov xim, aroma, saj thiab tsos ntawm cov txiv hmab txiv ntoo thiab zaub. Txawm li cas los xij, thaum siv rau cov khoom ntim khoom noj tiag tiag, qee qhov kev hloov kho yuav tsum tau hloov kho kom haum rau cov yam ntxwv ntawm cov khoom noj nws tus kheej, kom ua tiav cov txiaj ntsig zoo dua ntawm kev ntim khoom.
PLA tuaj yeem tsim ib puag ncig acidic tsis muaj zog ntawm qhov chaw ntawm cov khoom, uas muaj lub hauv paus ntawm antibacterial thiab antifungal. Yog tias siv lwm cov neeg sawv cev antibacterial ntxiv rau, tus nqi antibacterial ntau dua 90% tuaj yeem ua tiav, uas tuaj yeem siv rau kev ntim khoom antibacterial.
Piv nrog rau zaj duab xis LDPE, zaj duab xis PLA thiab zaj duab xis PLA/REO/TiO2, cov dej permeability ntawm PLA/REO/Ag composite zaj duab xis yog siab dua li ntawm lwm cov zaj duab xis. Nws tau xaus lus los ntawm qhov no tias nws tuaj yeem tiv thaiv kev tsim cov dej condensed thiab ua tiav cov nyhuv ntawm kev txwv tsis pub cov kab mob loj hlob; tib lub sijhawm, nws kuj muaj cov nyhuv bacteriostatic zoo heev.
Kab extrusion ib puag ncig PET/PLA: JWELL tsim cov kab extrusion sib luag rau PET/PLA daim ntawv, cov kab no nruab nrog lub tshuab degassing, thiab tsis tas yuav ziab thiab crystallizing unit. Cov kab extrusion muaj cov yam ntxwv ntawm kev siv hluav taws xob tsawg, cov txheej txheem tsim khoom yooj yim thiab kev saib xyuas yooj yim. Cov qauv ntsia hlau segmented tuaj yeem txo qhov viscosity poob ntawm PET/PLA resin, lub symmetrical thiab nyias-phab calender roller ua rau cov nyhuv txias thiab txhim kho lub peev xwm thiab daim ntawv zoo. Multi components dosing feeder tuaj yeem tswj tau feem pua ntawm cov khoom siv tshiab, cov khoom siv rov ua dua tshiab thiab cov khoom siv tswv kom meej, daim ntawv siv dav rau kev lag luam ntim thermoforming.
