Feem ntau siv ntau zaj duab xis hauv lub neej txhua hnub. Cov zaj duab xis no ua los ntawm cov khoom siv dab tsi? Cov yam ntxwv ua tau zoo ntawm txhua zaj duab xis yog dab tsi? Cov hauv qab no yog cov lus qhia ntxaws txog cov zaj duab xis yas uas feem ntau siv hauv lub neej txhua hnub:
Yas zaj duab xis yog ib zaj duab xis ua los ntawm polyvinyl chloride, polyethylene, polypropylene, polystyrene thiab lwm yam resins, feem ntau siv rau hauv kev ntim khoom, kev tsim kho, thiab ua ib txheej txheej, thiab lwm yam.
Yas zaj duab xis tuaj yeem faib ua
- Zaj duab xis kev lag luam: zaj duab xis cua tshuab, zaj duab xis calendered, zaj duab xis ncab, zaj duab xis cam khwb cia, thiab lwm yam;
- Zaj duab xis ua liaj ua teb, zaj duab xis mulch, thiab lwm yam;
-Cov yeeb yaj kiab rau kev ntim khoom (xws li cov yeeb yaj kiab sib xyaw rau kev ntim tshuaj, cov yeeb yaj kiab sib xyaw rau kev ntim khoom noj, thiab lwm yam).
Cov txiaj ntsig thiab qhov tsis zoo ntawm cov yas zaj duab xis:
Cov yam ntxwv ntawm kev ua yeeb yam ntawm cov yas tseem ceeb:
Zaj duab xis Polypropylene ob sab (BOPP)
Polypropylene yog ib hom thermoplastic resin uas tsim los ntawm kev sib xyaw ua ke ntawm propylene. Cov ntaub ntawv Copolymer PP muaj qhov kub qis dua ntawm kev hloov pauv cua sov (100 ° C), tsis tshua muaj pob tshab, tsis tshua muaj gloss, thiab tsis tshua muaj rigidity, tab sis muaj zog cuam tshuam ntau dua, thiab lub zog cuam tshuam ntawm PP nce nrog rau qhov nce ntawm ethylene. Qhov kub Vicat softening ntawm PP yog 150 ° C. Vim yog qib siab ntawm crystallinity, cov khoom no muaj qhov zoo heev ntawm qhov chaw tawv thiab khawb tsis kam. PP tsis muaj teeb meem tawg ntawm ib puag ncig.
Zaj duab xis polypropylene ob sab (BOPP) yog cov khoom ntim khoom uas yooj ywm thiab pob tshab uas tau tsim nyob rau xyoo 1960. Nws siv cov kab tsim khoom tshwj xeeb los sib tov cov khoom siv polypropylene thiab cov khoom ntxiv uas ua haujlwm tau zoo, yaj thiab sib tov ua daim ntawv, thiab tom qab ntawd ncab ua zaj duab xis. Nws yog siv dav hauv kev ntim khoom noj, khoom qab zib, luam yeeb, tshuaj yej, kua txiv hmab txiv ntoo, mis nyuj, ntaub, thiab lwm yam, thiab muaj lub koob npe nrov ntawm "Packaging Queen". Tsis tas li ntawd, nws kuj tseem siv tau rau kev npaj cov khoom muaj nqis ntxiv xws li cov ntaub hluav taws xob thiab cov ntaub me me, yog li cov yeeb yaj kiab BOPP muaj kev cia siab dav heev.
Zaj duab xis BOPP tsis yog tsuas muaj qhov zoo ntawm qhov ceev tsawg, tiv taus corrosion zoo thiab tiv taus kub zoo ntawm PP resin, tab sis kuj muaj cov khoom siv optical zoo, lub zog siab thiab cov khoom siv raw nplua nuj. Zaj duab xis BOPP tuaj yeem ua ke nrog lwm cov ntaub ntawv nrog cov khoom tshwj xeeb los txhim kho lossis txhim kho kev ua tau zoo. Cov ntaub ntawv siv feem ntau suav nrog zaj duab xis PE, zaj duab xis salivating polypropylene (CPP), polyvinylidene chloride (PVDC), zaj duab xis txhuas, thiab lwm yam.
Zaj duab xis Polyethylene tsawg ntom (LDPE)
Polyethylene zaj duab xis, uas yog PE, muaj cov yam ntxwv ntawm kev tiv thaiv dej noo thiab tsis tshua muaj dej noo permeability.
Polyethylene qis-density (LPDE) yog cov khoom siv hluavtaws tau los ntawm ethylene radical polymerization nyob rau hauv siab siab, yog li nws tseem hu ua "polyethylene siab". LPDE yog ib qho molecule branched nrog cov ceg ntawm ntau qhov ntev ntawm cov saw tseem ceeb, nrog txog 15 txog 30 ethyl, butyl lossis ntev dua ceg rau 1000 carbon atoms hauv cov saw tseem ceeb. Vim tias cov saw molecular muaj ntau cov saw ntev thiab luv luv, cov khoom muaj qhov ceev qis, mos, tsis kub, tsis kam zoo, tshuaj lom neeg ruaj khov, thiab feem ntau tsis kam acid (tshwj tsis yog cov kua qaub oxidizing muaj zog), Alkali, ntsev corrosion, muaj cov khoom zoo rwb thaiv tsev hluav taws xob. Translucent thiab glossy, nws muaj tshuaj lom neeg ruaj khov zoo heev, kub sealing, dej tsis kam thiab noo noo tsis kam, khov tsis kam, thiab tuaj yeem boiled. Nws qhov tsis zoo tseem ceeb yog nws qhov tsis zoo rau oxygen.
Nws feem ntau siv ua zaj duab xis txheej sab hauv ntawm cov khoom ntim khoom sib xyaw ua ke, thiab nws tseem yog cov yas ntim khoom siv dav tshaj plaws thiab siv tam sim no, suav txog ntau dua 40% ntawm kev siv cov yas ntim khoom. Muaj ntau hom polyethylene ntim zaj duab xis, thiab lawv cov kev ua tau zoo kuj txawv. Kev ua tau zoo ntawm ib txheej zaj duab xis yog ib qho, thiab kev ua tau zoo ntawm cov zaj duab xis sib xyaw yog kev sib koom ua ke. Nws yog cov khoom siv tseem ceeb ntawm kev ntim khoom noj. Qhov thib ob, polyethylene zaj duab xis kuj siv rau hauv kev tsim kho vaj tse, xws li geomembrane. Nws ua haujlwm ua cov dej tsis nkag hauv kev tsim kho vaj tse thiab muaj qhov permeability qis heev. Zaj duab xis ua liaj ua teb siv rau hauv kev ua liaj ua teb, uas tuaj yeem faib ua zaj duab xis tso, zaj duab xis mulch, zaj duab xis npog iab, zaj duab xis cia ntsuab thiab lwm yam.
Zaj duab xis Polyester (PET)
Zaj duab xis Polyester (PET), feem ntau hu ua polyethylene terephthalate, yog cov yas thermoplastic engineering. Nws yog cov khoom siv zaj duab xis ua los ntawm cov ntawv tuab los ntawm kev rho tawm thiab tom qab ntawd ncab ob sab. Zaj duab xis Polyester muaj cov yam ntxwv zoo heev, muaj zog, tawv thiab tawv, tiv taus kev sib txhuam, tiv taus kub thiab txias, tiv taus tshuaj lom neeg, tiv taus roj, huab cua nruj thiab khaws cia tsw qab. Ib qho ntawm cov khoom siv zaj duab xis sib xyaw tas mus li, tab sis kev tiv taus corona tsis zoo.
Tus nqi ntawm cov yeeb yaj kiab polyester yog qhov siab heev, thiab nws cov tuab feem ntau yog 0.12 hli. Nws feem ntau siv ua cov khoom siv sab nraud ntawm cov khoom noj rau kev ntim khoom, thiab muaj kev luam tawm zoo. Tsis tas li ntawd, cov yeeb yaj kiab polyester feem ntau siv ua cov khoom siv luam ntawv thiab ntim khoom xws li cov yeeb yaj kiab tiv thaiv ib puag ncig, cov yeeb yaj kiab PET, thiab cov yeeb yaj kiab dawb mis nyuj, thiab siv dav hauv kev lag luam xws li cov iav fiber reinforced plastics, cov ntaub ntawv tsim kho, kev luam ntawv, thiab tshuaj thiab kev noj qab haus huv.
Zaj duab xis yas nylon (ONY)
Lub npe tshuaj ntawm nylon yog polyamide (PA). Tam sim no, muaj ntau hom nylon uas tsim los ntawm kev lag luam, thiab cov hom tseem ceeb siv los tsim cov yeeb yaj kiab yog nylon 6, nylon 12, nylon 66, thiab lwm yam. Cov yeeb yaj kiab nylon yog cov yeeb yaj kiab tawv heev nrog kev pom tseeb zoo, ci ntsa iab zoo, lub zog tensile siab thiab lub zog tensile, thiab tiv taus kub zoo, tiv taus txias, tiv taus roj thiab cov kuab tshuaj organic. Kev tiv taus hnav zoo heev thiab kev sib tsoo tsis kam, mos mos, cov yam ntxwv zoo heev ntawm cov pa oxygen, tab sis cov yam ntxwv tsis zoo rau cov pa dej, kev nqus dej noo thiab cov dej noo permeability, tsis muaj cua sov salability, tsim rau ntim cov khoom tawv, xws li cov khoom noj roj, cov khoom noj nqaij, cov khoom kib, cov khoom noj ntim hauv lub tshuab nqus tsev, cov khoom noj steamed, thiab lwm yam.
Cast Polypropylene Zaj Duab Xis (CPP)
Tsis zoo li cov txheej txheem biaxially oriented polypropylene zaj duab xis (BOPP), cov zaj duab xis polypropylene cam khwb cia (CPP) yog cov zaj duab xis tsis ncab, tsis-oriented tiaj tiaj extrusion tsim los ntawm kev yaj casting thiab quenching. Nws yog tus cwj pwm los ntawm kev ceev ceev ntau lawm, cov zis siab, cov zaj duab xis zoo pob tshab, gloss, thickness uniformity, thiab kev sib npaug zoo ntawm ntau yam khoom. Vim tias nws yog cov zaj duab xis tiaj tiaj extruded, kev ua haujlwm tom qab xws li kev luam ntawv thiab kev sib xyaw ua ke yog qhov yooj yim heev. CPP yog siv dav hauv kev ntim khoom ntawm cov ntaub, paj, khoom noj, thiab cov khoom siv txhua hnub.
Yas zaj duab xis txhuas-coated
Cov yeeb yaj kiab aluminized muaj ob qho tib si yam ntxwv ntawm cov yeeb yaj kiab yas thiab cov yam ntxwv ntawm cov hlau. Lub luag haujlwm ntawm cov hlau txhuas plating rau ntawm qhov chaw ntawm cov yeeb yaj kiab yog los tiv thaiv lub teeb thiab tiv thaiv ultraviolet hluav taws xob, uas tsis yog tsuas yog ua kom lub txee ntev ntawm cov ntsiab lus, tab sis kuj txhim kho qhov ci ntawm cov yeeb yaj kiab. Yog li ntawd, cov yeeb yaj kiab aluminized yog siv dav hauv cov ntim khoom sib xyaw, feem ntau yog siv rau hauv cov khoom noj qhuav thiab puffed xws li biscuits, nrog rau cov ntim sab nraud ntawm qee cov tshuaj thiab cov tshuaj pleev ib ce.
