Nrog kev nce qib ntawm kev siv tshuab textile ntau lawm, ntau thiab ntau cov fibers tshiab tau dhau los ua cov ntaub ntawv raw rau textiles. Niaj hnub no, kuv yuav qhia koj txog kev txheeb xyuas cov cuab yeej siv siv polyester fiber ntau.
Nws tau nkag siab tias yav dhau los, vim tias tsis muaj txoj hauv kev tshuaj xyuas thiab tsis muaj peev xwm ntawm cov koom haum kuaj cov ntawv tshaj tawm zoo, cov tuam txhab tsis tuaj yeem txaus siab rau cov cai hauv tebchaws, thiab tib lub sijhawm ua rau muaj kev tsis sib haum xeeb hauv kev sau npe ntawm qee cov khoom polyester.
Dab tsi yog siv polyester (PET) fiber ntau?
Ntawd yog, pov tseg polyester (PET) polymer thiab pov tseg polyester (PET) cov ntaub ntawv pov tseg yog siv dua thiab ua tiav rau hauv polyethylene terephthalate fiber.
Nyob rau hauv layman cov ntsiab lus, recycled polyester fiber (tom qab no hu ua polyester recycled) yog hais txog cov polyester recycled (xws li lub raj mis flakes, ua npuas ncauj, pov tseg txhob lo lo ntxhuav, khib nyiab pulp, pov tseg textiles, thiab lwm yam) ua los ntawm cov txheej txheem rov ua dua. Ester fiber ntau.
Txoj Cai ntawm Kev Txheeb Xyuas
Raws li qhov sib txawv tseem ceeb ntawm cov txheej txheem ua dua tshiab ntawm polyester thiab nkauj xwb polyester, uas ua rau muaj cov yam ntxwv sib txawv, cov qauv ua tiav raws li cov xwm txheej tau teev tseg thiab kuaj ntawm cov kua chromatograph ua haujlwm siab. Raws li qhov sib txawv ntawm thaj chaw txheeb ze ntawm cov qauv hauv qab lub sijhawm khaws cia sib txawv, kom ua tiav lub hom phiaj ntawm kev txheeb xyuas qhov zoo.
Kauj ruam qhia
1. Methanolysis
2. o-Extraction
3. Kev ua haujlwm siab ua kua chromatography nrhiav kom tau
Kev kho cov kua dej ua tiav hauv qhov saum toj no 1 thiab 2 yog raws li kev ua haujlwm siab ua kua chromatography nrhiav tau.
4. Kev ua cov ntaub ntawv thiab kev txheeb xyuas
Recycled polyester yuav ua rau muaj kev hloov pauv hauv cov ntsiab lus thiab kev faib tawm ntawm macromolecular heterogeneous chain links thiab oligomers thaum lub sijhawm npaj, uas tuaj yeem siv los ua lub hauv paus rau kev txheeb xyuas cov khoom siv polyester thiab nkauj xwb polyester.
Qhov tshwj xeeb qhov chaw ncov thiab cov yam ntxwv ncov cov ntaub ntawv qhia nyob rau hauv cov lus hauv qab no.

Saib rau yav tom ntej
Nrog rau kev nce ntawm polyester noj thiab tib neeg txoj kev paub txog kev tiv thaiv ib puag ncig, ntau thiab ntau cov xim yog them rau kev rov ua dua ntawm polyester pov tseg. Kev siv cov khib nyiab polyester los tsim cov khoom siv polyester fiber ntau tuaj yeem txo cov nqi, txo cov roj noj, thiab txhim kho cov txiaj ntsig kev lag luam, uas yog qhov tseem ceeb rau kev txhim kho kev lag luam tshuaj fiber ntau.
Nyob rau tib lub sijhawm, nrog rau kev nce ntxiv ntawm cov khoom siv polyester, qhov teeb meem ntawm kev hloov pauv polyester thiab nkauj xwb polyester tau nyiam ntau thiab ntau dua los ntawm kev lag luam. Tus nqi sib txawv ntawm ob kuj qhia tau hais tias muaj kev sib raug zoo, thiab kev tshawb nrhiav qhov sib txawv ntawm ob lub Technology tau txais kev saib xyuas ntau dua.
