1. Yas muaj plasticity Raws li lub npe qhia, cov yas yog cov khoom uas tuaj yeem tus kheej. Lub npe hu ua yas ntawm cov yas yog tias cov khoom yas yuav ua kom mos los ntawm cua kub, thiab tom qab ntawd cov yas muag tau muab tso rau hauv pwm, uas tau tso cai kom txias thiab tom qab ntawd rov ua kom ruaj khov rau qhov khoom ntawm qee yam. Cov cuab yeej ntawm cov yas no kuj tseem muaj qee qhov tsis xws luag, uas yog, nws yooj yim muag thiab deform thaum kub, thiab qee cov yas yuav hloov pauv txawm tias thaum hotted nrog dej kub, yog li cov khoom yas feem ntau tsis haum rau kev sib cuag nrog dej npau.
2, yas tau elasticity Qee cov yas, zoo li hluavtaws hluavtaws, muaj qee qhov muaj qhov tsis txawv. Thaum nws ncab los ntawm sab nraud quab yuam, cov txheej txheem curled cov ncaj ncaj los ntawm qhov yooj, tab sis thaum qhov nro tawm, nws yuav rov qab mus rau nws lub qub curled xeev, uas ua rau cov yas ywj, xws li polyethylene thiab polyvinyl chloride. Zaj duab xis khoom. Tab sis qee cov yas siv kuj tsis yog ywj siab.
3. Plastics tiv taus corrosion Plastics tsis xeb hauv cov huab cua ntub dej zoo li hlau, tsis txhob lwj lossis tawm tsam los ntawm cov kab mob me me hauv qhov chaw noo zoo li ntoo, thiab cov kua qaub thiab alkali corrosion ntawm plastics. Yog li ntawd, cov yas siv feem ntau siv los ua cov kav dej thiab infusion rau tshuaj nroj tsuag, qhov rooj thiab lub qhov rais ntawm cov tuam tsev, thiab cov zoo li.
4. Cov yas muaj cov yam ntxwv insulating. Cov txheej txheem molecular saw ntawm plastics yog kev sib txuas ntawm cov atoms uas yog covalently sib khi. Cov lwg me me tsis yog tus ionized los yog tsis xa cov khoom siv hluav taws xob rau hauv tus qauv, yog li cov ntaub yas txhawm rau insulating. Cov yas siv tau los ua cov hnab hluav taws xob, hluav taws xob thaiv, hluav taws xob thaiv, thiab lwm yam.https://www.fhpails.com/
