1. UniversalBOPP zaj duab xis
BOPP zaj duab xis yog txheej txheem uas amorphous lossis ib nrab crystalline zaj duab xis yog ncab vertically thiab horizontally saum lub softening point thaum ua, ua rau muaj kev nce rau hauv cheeb tsam, ib tug txo nyob rau hauv thickness, thiab ib tug tseem ceeb kev txhim kho nyob rau hauv glossiness thiab transparency. Nyob rau tib lub sijhawm, vim yog kev taw qhia ntawm kev ncab cov molecules, lawv lub zog txhua yam, airtightness, noo noo tsis kam, thiab txias ua haujlwm tau zoo heev.
Cov yam ntxwv ntawm BOPP zaj duab xis:
Siab tensile zog thiab elastic modulus, tab sis tsis tshua muaj kua muag zog; Zoo rigidity, zoo heev elongation thiab khoov qaug zog tiv thaiv; Kub kub thiab txias tsis kam, nrog rau kev siv kub txog li 120℃. BOPP kuj tseem muaj qhov txias txias dua li cov PP zaj duab xis dav dav; High nto gloss thiab zoo pob tshab, haum rau siv raws li ntau yam ntaub ntawv ntim; BOPP muaj kev ruaj ntseg zoo. Tsuas yog cov acids muaj zog, xws li Oleum thiab nitric acid, nws yog insoluble nyob rau hauv lwm cov kuab tshuaj, thiab tsuas yog ib co hydrocarbons muaj o ntawm nws; Nws muaj cov dej tsis zoo thiab yog ib qho ntawm cov ntaub ntawv zoo tshaj plaws rau cov dej noo thiab noo noo, nrog rau qhov nqus dej tsawg dua 0.01%; Vim tias tsis zoo luam tawm, kev kho mob corona yuav tsum tau ua ua ntej luam ntawv kom ua tiav cov txiaj ntsig luam ntawv zoo; High static hluav taws xob, Antistatic tus neeg sawv cev yuav tsum tau ntxiv rau cov resin siv rau kev tsim cov yeeb yaj kiab.
Lub nto tsim ntawm matte BOPP yog txheej matte, ua rau cov tsos zoo li ntawv thiab xis rau kov. Lub extinction nto feem ntau tsis yog siv rau cov cua sov sealing. Vim tias muaj cov txheej txheem extinction, piv nrog BOPP dav dav, nws muaj cov yam ntxwv hauv qab no: qhov ploj tuag tuaj yeem ua lub luag haujlwm shading, thiab qhov glossiness ntawm qhov chaw kuj tseem txo qis; Yog tias tsim nyog, cov txheej txheem extinction tuaj yeem siv los ua lub hau kub; Lub extinction nto muaj zoo smoothness, raws li cov nto coarsening muaj anti adhesion thiab zaj duab xis yob tsis yooj yim rau lo; Lub zog tensile ntawm cov zaj duab xis extinction yog me ntsis qis dua li ntawm cov yeeb yaj kiab dav dav, thiab thermal stability kuj yog me ntsis phem dua li ntawm BOPP zoo tib yam.
Pearlescent zaj duab xis yog tsim los ntawm PP raws li raw khoom, ntxiv nrog CaCO3, pearlescent pigment, thiab roj hmab hloov tus neeg sawv cev, sib tov thiab biaxially stretched. Vim lub stretching ntawm PP resin molecules thaum lub sij hawm biaxial stretching txheej txheem, qhov kev ncua deb ntawm CaCO3 hais yog widened, uas ua rau tsim cov ntxeem tau npuas. Yog li ntawd, lub pearlescent zaj duab xis yog ib tug microporous ua npuas ncauj zaj duab xis nrog ib tug ceev ntawm 0.7g / cm ³ Sab laug thiab sab xis.
PP molecules poob lawv cov cua sov sealing zog tom qab biaxial orientation, tab sis raws li kev hloov pauv xws li roj hmab, lawv tseem muaj qee qhov kev sib khi thaum tshav kub kub. Txawm li cas los xij, cov cua sov sealing lub zog yog tsawg thiab yooj yim los tsim kua muag, ua rau lawv feem ntau siv rau hauv ntim cov dej khov, popsicles, thiab lwm yam khoom.
4. Thaum tshav kub kub kaw BOPP zaj duab xis
Ob chav sided tshav kub sealing zaj duab xis:
Cov zaj duab xis nyias no muaj cov qauv ABC, nrog rau ob qho tib si A thiab C qhov chaw raug cua sov kaw. Feem ntau yog siv los ua cov khoom ntim khoom noj, textiles, audio thiab video khoom, thiab lwm yam.
Single sided tshav kub sealing zaj duab xis:
Cov zaj duab xis nyias no muaj cov qauv ABB, nrog rau A-txheej yog cov txheej txheem cua sov. Tom qab luam tawm cov qauv ntawm B-sab, nws tau ua ke nrog PE, BOPP, thiab txhuas ntawv ci los ua ib lub hnab, uas yog siv los ua cov khoom ntim khoom noj khoom haus, dej haus, tshuaj yej, thiab lwm yam.
5. CPP zaj duab xis
Cam khwb cia CPP polypropylene zaj duab xis yog ib qho uas tsis yog ncab, tsis yog taw qhia polypropylene zaj duab xis.
Cov yam ntxwv ntawm CPP zaj duab xis yog siab transparency, zoo flatness, zoo kub-kub kuj, ib tug tej yam kev mob ntawm rigidity tsis poob yooj, thiab zoo tshav kub sealing. Homopolymer CPP muaj qhov nqaim qhov kub thiab txias rau kev sib khi thiab siab brittleness, ua rau nws tsim nyog siv los ua ib txheej ntim zaj duab xis,
Kev ua tau zoo ntawm copolymerized CPP yog qhov sib npaug thiab haum raws li cov khoom siv sab hauv rau cov khoom sib xyaw. Tam sim no, nws feem ntau yog co extruded CPP, uas tuaj yeem siv tag nrho cov yam ntxwv ntawm ntau yam polypropylene rau kev sib xyaw ua ke, ua rau kev ua haujlwm ntawm CPP ntau dua.
6. Tshuab moulded IPP zaj duab xis
IPP tshuab tshuab feem ntau yog tsim los siv txoj kev tshuab downward. Tom qab PP extruded thiab nthuav dav ntawm lub qhov ncauj ntawm lub qhov ncauj, nws tau pib txias los ntawm lub nplhaib cua thiab tam sim ntawd quenched thiab zoo li dej. Tom qab ziab, nws yog dov thiab tsim ua ib zaj duab xis cylindrical, uas tuaj yeem txiav rau hauv cov yeeb yaj kiab nyias. Tshuab moulded IPP muaj cov pob tshab, rigidity, thiab yooj yim lub hnab ua, tab sis nws cov thickness uniformity tsis zoo thiab cov zaj duab xis flatness tsis zoo txaus.
