Lub luag haujlwm ntawm polyester plasticizer hauv PVC cov khoom

1. Polyester plasticizer yog siv rau hauv cov khoom siv roj hmab los muab cov roj hmab thaum tshav kub kub, roj tsis kam, o tsis kam thiab kev tsiv teb tsaws, thiab tuaj yeem txhim kho kev ua haujlwm ntawm cov roj hmab ua haujlwm. Xws li txo cov viscosity ntawm cov roj hmab compound, txhim kho cov resilience thiab elongation ntawm vulcanization, thiab txo cov tensile zog thiab tearing zog ntawm cov roj hmab compound. Nws yog feem ntau siv hauv styrene-butadiene roj hmab thiab cov khoom siv roj hmab nitrile.

2. Hauv EVA-VC graft copolymer resin, polyester plasticizer tuaj yeem siv los ua ib qho kev hloov kho nyuaj. Nws yog siv nyob rau hauv formulation ntawm PVC qhov rooj, qhov rais thiab lwm yam profiles, ntxiv 6-10 qhov chaw ntawm polyester plasticizer li Tom qab cov additives, nws cov khoom muaj zoo heev huab cua tsis kam thiab cuam tshuam tsis kam;

3. Polyester plasticizer tuaj yeem muab ntxiv txog 20 feem pua ​​~ 70 feem pua ​​hauv cov khoom muag PVC. Tshwj xeeb nitrile roj hmab hmoov ua nrog polyester plasticizer tuaj yeem siv los hloov kho rau PVC, ABS resin, phenolic resin, thiab lwm yam., uas tuaj yeem ua rau cov khoom tawv tawv thiab txhim kho qhov txias. Nitrile hmoov ua los ntawm polyester plasticizer yog cov khoom siv zoo tagnrho rau kev tsim cov khoom siv roj-resistant.

4. Siv polyester plasticizers li PVC modifiers thiab siv cov tsim PVC modifiers nyob rau hauv nruj PVC formulations yuav txhim kho lub brittleness ntawm PVC resins thiab muaj ib tug zoo heev toughening nyhuv. Polyester plasticizer yog siv rau PVC cov ntaub ntawv, muaj kev ua tau zoo heev thiab khawb kuj, tshwj xeeb tshaj yog haum rau ntau yam khoom yas uas tiv taus roj thiab dej.

5. Nyob rau hauv cov txheej txheem ntawm kev siv polyester plasticizer nyob rau hauv PVC, PVC resin thiab kua plasticizer (DOP) yuav tsum tau absorbed tag nrho ua ntej ntxiv cov polymer polyester plasticizer. Txoj kev ua haujlwm tshwj xeeb yog PVC hauv cov khoom sib tov Thaum lub plasticizer yog absorbed tag thiab nyob rau hauv cov hmoov qhuav, ntxiv polyester plasticizer. Yog tias PVC resin, DOP, thiab polyester plasticizer tau ntxiv rau tib lub sijhawm, polyester plasticizer yuav xub nqus DOP thiab tos rau lwm cov plasticizers ua ntej PVC, uas yuav ua rau tsis tiav plasticization ntawm PVC, cov khoom ua tau zoo thiab cov khoom siv PVC Cov yam ntxwv yuav poob qis. .

Vim hais tias polyester plasticizers muaj zog polarity, affinity thiab cov yam ntxwv ntawm lwm cov kua plasticizers, thaum polyester plasticizers tuaj yeem nyiam thiab txhim kho qhov chaw tsiv teb tsaws ntawm lwm cov plasticizers rau PVC cov khoom, lawv tuaj yeem nyiam thiab kho qhov chaw tsiv teb tsaws ntawm lwm cov plasticizers rau PVC khoom. , Polyester plasticizers raug suav tias yog cov yas ruaj khov. Polyester plasticizers tuaj yeem siv rau hauv ntau yam khoom siv PVC, tshwj xeeb tshaj yog cov khoom siv ua haujlwm tsis zoo rau cov khoom siv high-end PVC.
