Lub Npe Cov Ntaub Ntawv (ua cov yeeb yaj kiab)
Cov no yog cov ntaub ntawv siv los tsim cov kab noj hniav lossis "blister" uas tuav cov khoom. Lawv yuav tsum tau ua pwm, ruaj, thiab muab cov pa thaiv zoo tiv thaiv ya raws, oxygen, thiab lwm qhov chaw ib puag ncig.
Hom:
PVC (polyvinyl chloride):
Dav siv dav vim nws tus nqi qis, kev pom tseeb, thiab yooj yim ntawm thermoforming.
Haum rau cov khoom noo-noo-rhiab.
Tsis zoo tagnrho rau cov khoom uas yuav tsum muaj kev tiv thaiv loj.
PVDC (Polyvinylidene chloride) -Cov PVC:
Muab cov dej noo zoo dua thiab cov pa oxygen cov khoom siv ntau dua li PVC.
Feem ntau siv rau cov kws tshuaj thiab khoom lag luam.
Coc (cyclic ankefin copolymer):
High txuj ci, zoo heev noo noo barrier, thiab tshuaj lom neeg kuj.
Feem ntau siv rau cov khoom siv rhiab tshuaj.
Tsiaj (polyethylene Terephthalate):
Muaj zog, nruj, thiab pob tshab.
Muab cov teeb meem zoo thiab yog rov ua dua tshiab.
Feem ntau siv rau cov neeg siv khoom thiab khoom siv hluav taws xob.
Pp (polypropylene):
Cov tshuaj zoo tsis kam thiab kav ntev.
Haum rau cov khoom yuav tsum kom tsis muaj menyuam (piv txwv li, cov cuab yeej kho mob).
Apet (Amorphod Polyethylene Terephthalate):
Ntshiab, tsis yeem, thiab rov ua dua tshiab.
Feem ntau siv rau cov zaub mov thiab cov siv khoom ntim khoom.
PVC \/ CCTFE (Polychlorotrifluoroethylene):
Muaj cov khoom muaj noo noo zoo heev.
Siv rau kev noo noo-rhiab khoom.
