Self-adhesive labels PET thiab PVC sib txawv

Thaum nws los txog rau cov ntawv nplaum rau tus kheej, txhua tus yuav tsum xub xav txog PET thiab PVC, tab sis koj paub ntau npaum li cas cov ntawv ua los ntawm PET thiab PVC? Hnub no, cia kuv qhia koj:

Qhov txawv 1
Cov khoom siv raw khoom sib txawv:
PVC, uas yog, polyvinyl chloride, thawj xim yog me ntsis yellowish pob tshab thiab glossy.
PET, uas yog, polyethylene terephthalate, muaj qhov pom tseeb zoo heev.
Lub zog ntawm cov khoom siv raw yog txawv:
PVC, uas yog, polyvinyl chloride, muaj qhov pom tseeb zoo dua li cov polyethylene thiab polystyrene siab, tab sis phem dua li polyethylene. Nws tau muab faib ua mos thiab tawv polyvinyl chloride raws li qhov sib txawv ntawm cov khoom siv hloov kho. Cov khoom muag muag yog mos thiab tawv, thiab xav tias nplaum. Lub zog ntawm cov khoom siv tawv yog siab dua li cov khoom siv uas tsis tshua muaj siab siab polyethylene, tab sis qis dua li ntawm polypropylene, thiab kev ua kom dawb yuav tshwm sim ntawm qhov khoov.
PET, uas yog, polyethylene terephthalate, muaj zog compressive thiab ductility zoo dua li polyethylene thiab polyvinyl chloride, thiab tsis yooj yim tawg.
Kev siv cov khoom siv raw yog txawv:
PVC, uas yog, cov khoom siv ntawm polyvinyl chloride: boards, kav, khau khau, khoom ua si, qhov rais thiab qhov rooj, cable tawv, ntawv sau, thiab lwm yam.
PET, uas yog, feem ntau daim ntawv thov ntawm polyethylene terephthalate: nws yog feem ntau pom nyob rau hauv cov ntaub ntawv cov khoom uas yuav tsum tau siab waterproof, alkali-resistant, tshuaj-resistant, tshav kub-resistant thiab lwm yam khoom, siv rau cov khoom siv hauv chav dej, khoom tu tawv nqaij, ntau yam hauv tsev. khoom siv, khoom siv kho tshuab, thiab lwm yam.

Qhov txawv 2
1. PVC tsis yog recyclable, tab sis PET yog recyclable;
2. Yog tias koj siv PET lub raj mis thiab cov ntawv PVC, koj yuav tsum tshem cov ntawv PVC thaum rov ua dua lub raj mis; thaum PET daim ntawv lo tsis tas yuav raug tshem tawm;
3. PET muaj cov khoom zoo heev dielectric, nrog zoo tiv thaiv fouling, anti-scratch, kub tsis kam thiab lwm yam khoom;
4. PVC thiab PET muaj cov khoom zoo sib xws. Nws muaj qhov ua tau zoo dua thiab muaj kev xav zoo dua li PET, tab sis PVC muaj qhov tsis zoo degradability thiab muaj kev cuam tshuam tsis zoo rau kev tiv thaiv ib puag ncig.
5. PET feem ntau muaj PET dawb lossis pob tshab PET, thiab tseem tuaj yeem ua rau kub lossis nyiaj saum npoo, uas zoo nkauj heev.
6. Cov ntawv PET muaj cov khoom siv zoo, muaj zog tiv thaiv, roj tsis kam thiab roj tsis kam. Qhov kub thiab txias kuj tseem muaj zog dua li ntau cov yas, yog li cov ntawv nplaum hauv chav ua noj peb feem ntau pom yog ua los ntawm PET + aluminium ntawv ci.
7. Cov khoom siv PET muaj cov pob tshab zoo thiab zoo softness hauv qab 25u. Nws yog tsuas yog siv rau tsheb kauj vab thiab maus taus decals thiab qee cov khoom siv hluav taws xob piav qhia cov ntawv. PET Dawb yog siv rau hauv cov ntawv xov tooj ntawm tes roj teeb, thiab lwm yam.
8. Qhov sib txawv tseem ceeb ntawm PVC yog tias nws muaj qhov tsis zoo thermal stability thiab yooj yim hnub nyoog los ntawm lub teeb, cua sov thiab oxygen. Tsis tas li ntawd, ntau cov tshuaj lom neeg feem ntau yog ntxiv thaum lub sij hawm tsim cov txheej txheem PVC.

Qhov txawv 3
PET: tawv, tawv, siab zog, ci ntsa iab, ib puag ncig tus phooj ywg, pob tshab thiab ntau xim. Qhov tsis zoo yog tias PET high-frequency heat bonding yog qhov nyuaj dua thiab tus nqi kim dua PVC. Cov khoom no feem ntau yog hloov los ntawm PVC los ntawm cov neeg siv uas xav tau cov khoom zoo thiab kev tiv thaiv ib puag ncig. Cov ntaub ntawv PET feem ntau yog siv los ua lub raj mis yas, lub thawv ntim khoom noj, thiab lwm yam.
PVC: Cov khoom siv blister feem ntau yog mos, tawv, thiab yas. Nws tuaj yeem ua pob tshab thiab ntau yam xim. Pob tshab PVC feem ntau yog siv los ntim khoom siv hluav taws xob, tshuaj pleev ib ce, khoom ua si, khoom plig, thiab lwm yam khoom.
