Polymers tau dhau los ua qhov xav tau hauv txhua qhov ntawm lub neej niaj hnub no, thiab kev txhim kho tsis ntev los no hauv lawv cov khoom lag luam thiab kev ua haujlwm tau nthuav dav ntxiv rau kev siv cov yas, thiab hauv qee qhov kev thov, polymers tau hloov pauv lwm cov ntaub ntawv xws li iav, hlau, ntawv thiab ntoo.
Tab sis qhov ua tau zoo ntawm cov ntaub ntawv yuav ua rau poob qis lossis poob zoo li daj thiab qhov txo qis ntawm cov txheeb ze molecular loj, tawg ntawm qhov chaw thiab tsis ci, vim nws cov yam ntxwv ntawm cov qauv thiab lub cev lub cev, nrog rau kev raug cua sov, lub teeb thiab cua sov, oxygen, ozone, dej, kua qaub, alkali, kab mob thiab enzymes thiab lwm yam sab nraud. Dab tsi phem dua, qhov kev puas tsuaj yuav tshwm sim hauv qhov muaj zog cuam tshuam, lub zog tensile, elongation thiab lwm yam khoom siv dag zog, uas cuam tshuam rau ib txwm siv cov ntaub ntawv polymer.
Yog li ntawd, kev tiv thaiv kev laus ntawm cov ntaub ntawv polymer tau dhau los ua teeb meem uas kev lag luam polymer yuav tsum daws. Tam sim no, muaj ntau txoj hauv kev los txhim kho kev tiv thaiv kev laus ntawm cov khoom siv polymer, ntawm qhov uas txoj hauv kev zoo dua thiab cov txheej txheem ib txwm yog ntxiv cov tshuaj tiv thaiv kev laus, uas tau siv dav vim tias tus nqi qis thiab tsis xav tau hloov pauv cov txheej txheem tsim khoom uas twb muaj lawm.
Tsuas yog cov tshuaj polymer uas tau siv hauv cov haujlwm tshwj xeeb, lub tuam txhab tuaj yeem muab cov hauv qab no cov yas ntxiv rau:
