Yas tau dhau los ua ib feem ntawm peb lub neej. Los ntawm cov khoom ntim rau cov khoom siv hauv tsev, yas yog nyob txhua qhov chaw. Raws li qhov tshwm sim, kev lag luam plastics tau loj hlob sai, thiab yog li qhov kev thov rau cov khoom siv yas ua tau zoo. Ib qho ntawm cov tshuab uas tseem ceeb rau kev lag luam plastics yog cov plasticizer.
Plasticizer yog lub tshuab uas yaj thiab pwm cov ntaub ntawv yas rau hauv cov duab uas xav tau. Nws muaj ob lub ntsiab Cheebtsam - lub extruder thiab lub tshuab molding. Ib qho extruder melts cov khoom yas thiab hla nws los ntawm kev tuag los tsim cov duab uas xav tau. Lub tshuab molding ces txias thiab solidifies cov yas kom nws cov duab.
Lub tshuab plasticizing yog tsim rau kev ua ntau yam yas, xws li PVC, polyethylene, polypropylene, thiab polystyrene. Nws yog dav siv hauv kev tsim cov khoom siv yas, xws li cov kav dej yas, cov khoom ua si, cov khoom siv hauv tsev, cov khoom siv tsheb, thiab cov khoom siv hluav taws xob.
Plasticizers muaj ntau yam zoo. Ua ntej, nws lav cov khoom tsim tau zoo thiab ua haujlwm zoo ib yam. Lub tshuab tuaj yeem ua cov ntaub ntawv yas zoo yam tsis muaj kev cuam tshuam rau nws qhov kev ua tau zoo thiab kav ntev. Qhov thib ob, nws ua kom cov khoom tsim tau los ntawm kev txo lub sijhawm ua haujlwm. Lub tshuab tuaj yeem yaj sai sai thiab zoo li cov ntaub ntawv yas, ua rau nws zoo tagnrho rau ntau lawm. Thaum kawg, nws txo qhov cuam tshuam ib puag ncig los ntawm kev ua kom pom kev siv cov ntaub ntawv yas. Lub tshuab minimizes yas pov tseg los ntawm kev siv cov ntaub ntawv yas los tsim cov khoom xav tau.
Raws li qhov tshwm sim, plasticizer tau dhau los ua cov cuab yeej tseem ceeb hauv kev lag luam plastics. Nws txhawb kev lag luam los ntawm kev ua kom muaj txiaj ntsig zoo ntawm cov khoom siv yas thiab kev tsim cov khoom yas zoo. Raws li qhov kev thov rau cov khoom yas txuas ntxiv zuj zus, cov yas yas yuav ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li qhov xav tau thiab tsav kev lag luam mus tom ntej.
