Polyester plasticizers tuaj yeem siv hauv cov khoom lag luam PVC, tshwj xeeb yog ntxiv rau cov khoom lag luam qib siab PVC. Polyester plasticizers siv dav dav thiab muaj cov cuab yeej pom tseeb hauv cov khoom lag luam PVC. Siv dav hauv cov roj-resistant cable, roj kav dej, cov khoom siv dej ua ke, cov khoom siv tawv tawv, khau ntaub, kub txheej hlau txheej txheej, dej tank sealing ib daim hlab, gaskets thiab mouldings rau ntau yam khoom siv (nrog rau cov cuab yeej siv tub yees, tsheb tsav); qib high-qib kho kom zoo nkauj sab hauv tsev; kab xev hluav taws xob; tshwj xeeb cov khoom lag luam tiv thaiv cov roj thiab roj av, thiab lwm yam. Hauv nqe lus ntawm kev sib cuag khoom noj, nws suav nrog ntim ntim, dej haus rau hoses, tshuab ua khoom noj thiab lub hau ntim roj.
Lub luag haujlwm ntawm polyester plasticizer hauv pvc khoom:
1. Polyester plasticizer yog siv hauv cov khoom siv roj hmab los muab cov roj hmab ua kom sov, roj tsis kam, o tuaj yeem hloov thiab tsiv mus rau vulcanization, thiab tuaj yeem txhim kho kev ua tiav ntawm cov khoom siv roj hmab ua tshuab. Xws li kev txo cov viscosity ntawm cov roj hmab compound, txhim kho kev thev taus ntev thiab elongation ntawm vulcanization, thiab txo qhov tensile lub zog thiab kua muag lub zog ntawm cov roj hmab compound. Nws yog feem ntau siv rau hauv styrene-butadiene roj hmab thiab cov khoom lag luam roj hmab nitrile.
2. Hauv EVA-VC graftmer copolymer resin, polyester plasticizer tuaj yeem siv los ua kev kho kho qhov nyuaj. Nws yog siv nyob rau hauv kev tsim ntawm PVC qhov rooj, qhov rai thiab lwm qhov profile, ntxiv 6-10 qhov ntawm polyester yasizer raws li Tom qab cov ntxiv, nws cov khoom muaj huab cua zoo thiab tiv taus cuam tshuam;
3. Polyester plasticizer tuaj yeem muab ntxiv 20% ~ 70% hauv cov khoom lag luam muag muag PVC. Cov roj ntsha tshwj xeeb nitrile roj hmab hmoov tsim nrog polyester plasticizer tuaj yeem siv los hloov kho rau PVC, ABS resin, phenolic resin, thiab lwm yam, uas tuaj yeem nce cov khoom tawv thiab txhim kho qhov cuam tshuam txias. Nitrile hmoov ua los ntawm polyester yasizer yog cov khoom lag luam zoo tagnrho rau kev tsim cov khoom siv roj-resistant.
4. Siv cov polyester plasticizers li PVC hloov kho thiab siv cov tsim cov khoom tsim ua PVC txhav hauv cov PVC tsim cov qauv tuaj yeem txhim kho lub brittleness ntawm PVC resins thiab muaj qhov ua tau zoo toughening. Polyester plasticizer yog siv rau cov ntaub ntawv PVC, muaj kev ua haujlwm zoo heev thiab khawb tsis kam, tshwj xeeb tshaj yog haum rau ntau cov khoom yas uas tiv taus cov roj thiab dej.
5. Hauv cov txheej txheem ntawm kev siv cov yas polyester yas hauv PVC, PVC cob thiab kua yas kua roj (DOP) yuav tsum tau nqus ua ntej tso cov kua roj polymer polymer. Cov txuj ci kev ua haujlwm tshwj xeeb yog los nqus cov PVC hauv cov khoom tov Thaum cov yas ua nyob rau hauv daim ntawv hmoov qhuav, ntxiv cov polyester yas. Yog tias PVC cob, DOP, thiab polyester plasticizer ntxiv rau tib lub sijhawm, cov polyester yasizer thawj yuav nqus DOP thiab tos rau lwm cov yas ua ntej PVC, uas yuav ua rau kom tsis tiav cov khoom tiav ntawm PVC, cov khoom lag luam ua tiav thiab cov khoom lag luam PVC Cov yam ntxwv yuav poob Cov.
Vim tias polyester plasticizers muaj lub zog polarity, kev sib raug zoo thiab cov yam ntxwv ntawm lwm cov kua yas ua kua, thaum polyester plasticizers tuaj yeem nyiam thiab txhim kho qhov chaw tsiv ntawm lwm cov plasticizers rau cov khoom lag luam PVC, Polyester plasticizer tuaj yeem siv ntau hauv cov khoom lag luam PVC, tshwj xeeb tshaj yog indispensable ua cov khoom siv rau siab -end cov khoom lag luam PVC.
