Kev ntim khoom siv tau yog ib hom ntim ua los ntawm cov khoom siv hloov tau yooj yim uas ua ke ntawm cov yas, cov duab ua ke xws li kev ua haujlwm sab nraud, thiab kev ruaj ntseg. Qee cov ntaub ntawv siv hauv kev ntim khoom siv yas yas yas yas, txhuas cov ntaub ntawv siv roj ntsha, cov ntaub ntawv ntim khoom siv xyoob ntoo, biodegradable ntim thiab lwm yam.
Cov ntawv thov ntim khoom lag luam muaj xws li: hnab, qhwv-ib ncig ntawm zaj duab xis, chav tsev muag khoom, ntsws qhwv, ncab cov liaj teb thiab ntim cov taub ntim. Cov khoom tshwj xeeb ntawm cov khoom lag luam ntawm cov khoom siv tshuab zog, kev tiv thaiv cov zaub mov ntawm kev sib kis), kub siab, rov ua dua, thiab tus nqi ua tau zoo yog dab tsi ua lawv sawv tawm.
Ntawm lawv, cov yeeb yaj kiab yas yog siv hauv kev ntim khoom siv tau yooj yim hauv cov khoom siv sib txawv heev, suav nrog cov hauv qab no:
Polyethylene (PE): Xws li cov roj av qis polyethylene (LDPE) thiab linear tsawg polyethylene (LLDPE), muaj lldpe (LLDPE)
Polypropylene (pp): feem ntau siv nyob rau hauv kev tsim cov zaj duab xis, nrog cov kub ua haujlwm tiv taus zoo thiab cov tshuaj tua kab mob, feem ntau siv hauv cov khoom siv hauv paus.
Polyester (Tsiaj): feem ntau yog siv raws li sab nraud lossis nruab nrab txheej ntawm ntim vim nws cov kws kho tshuab zoo thiab pob tshab thiab kev ua kom zoo nkauj.
Nylon (PA): Muab cov khoom muaj kuab zoo thiab feem ntau siv rau kev ntim khoom kom xav tau kev ua tau zoo siab.
Ethylene vinyl acetate copolymer (EVA): Muab kev hloov pauv tau zoo thiab cov khoom nplaum thiab feem ntau yog siv los ua cov txheej txheem cua sov txheej.
Polyvinylidene Dichhloride (PVDC): Muaj huab cua siab heev thiab noo noo pov tseg cov khoom siv, kheev siv nyob rau hauv cov ntim uas yuav tsum tau ua lub sijhawm ntev.
Ethylene Vinyl cawv copolymer (evoh): Muab cov oxygen cov roj oxygen zoo li txheej txheej txheej.
Polyvinyl chloride (PVC): Siv hauv qee cov ntawv thov, tab sis nws siv yog txwv vim kev txhawj xeeb ib puag ncig thiab kev noj qab haus huv.
Cov ntaub ntawv siv xyoob xyoob ntoo: xws li polylactic acid (PLA), raws li ib puag ncig cov neeg hloov pauv nrog cov khoom lag luam zoo.
Biodegradable Cov Ntaub Ntawv: Puas tau tsim los txo cov kev cuam tshuam ib puag ncig ntawm kev ntim khoom.
Multium Txheej Txheej Co-Extruded Composite Films: Ntau txheej kev sib txuam ntawm PA, EVOH, PVDC nrog cov resins xws li PE, EVA, PP, thiab lwm yam los muab cov teeb meem loj.
Cov ntaub ntawv no tuaj yeem siv rau ib tus zuj zus lossis sib xyaw ua ke los ua cov yeeb yaj kiab sib xyaw kom tau raws li cov khoom sib txawv, cov tshuab hluav taws xob kub, muaj zog thiab zoo nkauj. Hauv kev ntim khoom siv tau, cov ntaub ntawv no feem ntau ua ke los ntawm kev lamination lossis co-extrusion cov txheej txheem los tsim cov ntaub ntawv ntim nrog cov haujlwm tshwj xeeb.
Yuav daws cov teeb meem ntawm PE, PP, Tsiaj, Pa thiab lwm yam ntaub ntawv hauv kev ua cov txheej txheem extrusion prone rau kev tsis xws luag?
Cov ntaub ntawv saum toj no, xws li PE, PP, tsiaj, PA, thiab lwm yam. Feem ntau, cov tuam ntxhab tseem ceeb yuav ntxiv cov tshuaj fluorinated polymer ppa ua pab txhawm rau txhim kho kev ua haujlwm. Txawm li cas los xij, nyob rau hauv xyoo tsis ntev los no, nrog rau kev tiv thaiv loj hlob ntawm kev tiv thaiv ib puag ncig thiab nrhiav cov kev pabcuam fluorinated fluorinated Guorinated Fluorinated AIDS tau dhau los ua ib qho haujlwm sai.
Thoob ntiaj teb, PFAs tau siv dav hauv ntau cov khoom lag luam thiab cov neeg siv khoom, tab sis nws muaj kev phom sij rau ib puag ncig thiab tib neeg kev noj qab haus huv tau ua rau muaj kev txhawj xeeb thoob plaws. Nrog rau kev ua haujlwm tshuaj European (cha) ua rau pej xeem daim qauv hluav taws xob pfas.
Nyob rau hauv 2023, site silike yog tau teb rau cov qauv ntawm lub sijhawm thiab nqis peev txhais tau tias kev xav zoo kawg nkaus thiab kev xav tshiab kom ua tiavPfas-dawb polymer ua pab pab (ppas), uas ua rau muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov. Cov khoom no ua kom ua kom tau cov khoom ua tau zoo thiab ua tau zoo thaum tsis txhob muaj kev pheej hmoo ib puag ncig thiab kev noj qab haus huv uas cov khoom sib txuas PFAs PFA.
Silike Silimer Pfas-Dawb ppa masterbatch yog pfas-dawb polymer ua pab (PPA)qhia los ntawm silicone. Cov additive yog ib qho kev hloov kho polysiloxane, uas siv kom zoo dua ntawm cov pab pawg polysiloxanes ntawm cov pab pawg hloov kho thiab ua raws li cov cuab yeej ua thaum ua tiav.
Silike Silimer Pfas-Dawb PPA masterbatchtuaj yeem ua tau zoo kawg nkaus hloov fluorine-raws li cov kev pab cuam kom zoo, thiab cov kab mob nto thiab cov nqaij ntuag, txhim kho cov coefficient ntawm kev sib txhuam , txhim kho kev tsim khoom thiab cov khoom lag luam zoo, tab sis kuj tseem ua phooj ywg zoo thiab muaj kev nyab xeeb.
Silike Silimer Pfas-Dawb PPA masterbatchMuaj ntau cov ntawv thov, tsis yog tsuas yog rau cov yeeb yaj kiab yas, tab sis kuj rau cov xov hlau thiab cabes, xim masterbatches, petrochemical kev lag luam thiab li ntawd.
Yog tias koj nyob hauv kev siv hluav taws xob yooj ywm thiab saib txhawm rau txhim kho kev sib tw ntawm koj cov khoom lag luam, koj tuaj yeem sivSilike ntawm pfas-dawb ppa ntxiv.
