Taug txuj kev nyuaj tau tshwm sim thaum ntxov xyoo 1960, thaum nws yog artificially tsim thiab ua los ntawm yas tshuaj fiber ntau cov khoom. Los ntawm cov kev pom ntawm qhov pom, cov nyom hniav seem ntawm cov khoom cua dag ntawm lub sijhawm ntawd tiaj tus thiab tsis muaj lub siab phem.
Raws li ib yam ntawm cov qauv ntawm cov xim cog qoob loo, cov khoom siv dag tsuas tsis tuaj yeem ua kom tau raws li qhov kev xav tau ntawm kev ua si, tab sis tseem muaj kev yooj yim tso thiab muaj zog siv; thiab xim yog kaj lug, qhov kov yog qhov zoo, nyom yog tiaj tus, thiab nws tsis tas yuav haus dej kom tswj tau nws. Yuav kom ua tau raws li cov kev ua si ntawm txhua lub sijhawm, yuav tsum tau ua kom muaj qhov phom sij ntawm lub cev ntev ntev los ntawm ultraviolet rays, cua, nag thiab lwm yam mob hnyav sab nraud, thiab muaj lub neej ua haujlwm ntev.
Yuav kom ua tiav lub hom phiaj no, nws yog qhov tsim nyog los txhim kho txoj kev ua haujlwm ntawm cov khoom siv dag zog ntawm lub hauv paus ntawm qhov tseem ceeb, yog li txuas ntxiv rau nws txoj haujlwm thiab txhawb nws txoj kev loj hlob ntawm kev tiv thaiv ib puag ncig, kev lag luam thiab kev ua si. Cov khoom siv ua si tam sim no siv los ntawm cov khoom siv hluav taws xob polymer, thiab nws cov khoom tseem ceeb yog cov khoom uas tsis yog biodegradable xws li polyethylene.
Txawm hais tias tej ntaub ntawv muaj zoo lub cev, tshuaj lom neeg thiab cov khoom siv dag zog, cov ntaub ntawv polymer muaj qhov qis tsis tshua muaj zog, cov neeg tsis muaj peev xwm muaj peev xwm nqa tau thiab nws nyiam hnav. Xws li cov khoom cua dag yuav ntev yuav raug rau kev siv heev thiab hnav zoo. puas tsuaj. Vim li no, tau npaj los txhim kho txoj kev hnyav ntawm cov kab mob polymers nrog ntau hom fillers, thiab kawm txog qhov kev sib txuas ntawm cov ntaub ntawv siv khoom thiab cov khoom matrix.
Nws tau raug pov thawj tias cov ntaub ntawv sau rau hauv cov kab sau tau polymer ntawm cov khoom siv dag tau ua tau zoo ua kom cov cwj pwm coj ntawm cov substrate thiab nce nws cov kev pab cuam lub neej. Yog li ntawd, rau kev ua si dag cai, kawm kev hnav lub cev yog ua tau kawm txog kev hnyav ntawm cov kabmob polymer.
