Tom qab txheej txheem cej luam ntawm BOPP zaj yeeb yaj kiab, koj puas muaj cov ntxhib rau ntawm no ubiquitous cov khoom? Hauv cov blog no, peb yuav tob tob rau peb cov kev pom rau nws cov txiaj ntsig thiab kev ua kom zoo, yog li zoo dua cov neeg them tus nqi hluav taws xob.
Dab tsi yog bopp zaj duab xis
Biaxially Oriented Polypropylene (Bopp) Zaj duab xis tau hloov kho lub tshuab ntim khoom txij li nws cov lus qhia hauv xyoo 1970. Cov cuab yeej tshiab no, ncab ob qho tib si mechanically thiab manually siv cov txheej txheem hla kev sib xyaw, muaj kev sib txawv ntawm cov khoom uas tau ua rau nws tsis tseem ceeb hauv ntau yam kev siv.
Cov yam ntxwv tseem ceeb ntawm BOPP
Tsis muaj kob thiab ntxhiab tsw qab
Tsis-toxic muaj pes tsawg
Balanced rigidity thiab tawv
Ua tau zoo heev kev tiv thaiv
High tensile lub zog (cov nqi raug nyob ntawm 130-300 mpa)
Tshwj xeeb pob tshab (nce txog 90% lub teeb kis)
Cov khoom no tau tso rau tom BOPP ua ib qho khoom siv hla ntau yam kev lag luam, los ntawm cov zaub mov ntim khoom noj.
Qhov Zoo Ntawm Bopp Zaj Duab Xis
Cov Khoom Siv Lub Cev
Bopp excels nyob rau hauv lub zog thiab durability, nrog lub tensile lub zog uas tuaj yeem ncav cuag 300 MPa hauv lub tshuab kev. Nws cov ua kom pom tseeb zoo nkauj, nrog lub teeb sib kis tau nce txog 90%, txhim kho cov khoom pom ntawm lub khw. Zaj duab xis sab ruaj ruaj ruaj ruaj kom ua tau zoo sib xws thoob plaws ntawm ntau yam kev siv 4% ntawm 130 ° C.
Kuj rau punctures thiab flex tawg ua rau bopp zoo rau kev tiv thaiv kev tiv thaiv. Piv txwv li, ib qho kev ua yeeb yaj kiab loj 20-micron
Tshuaj Tshuaj Muaj Zog
BOPOP kev ua raws li cov ntawv sau ua ke tiv thaiv ya raws, muaj kuab paug, thiab cov tshuaj lom neeg. Nws cov dej vapor kis tus nqi (WVTR) tuaj yeem qis li 4-5 g / m² / day ntawm 38 ° C thiab 90% txheeb ze cov av noo, ua rau nws zoo tshaj plaws rau noo noo-rhiab khoom.
Cov yeeb yaj kiab cov roj thiab roj tsis kam, nrog cov kev tsim nyog tshaj 7 ntawm cov khoom xeem cov khoom ntsuas, ntxiv nthuav dav nws qhov kev siv tau. Cov khoom siv no ua rau kev xaiv tau zoo rau cov khoom noj ntim khoom thiab siv, qhov twg kev tiv thaiv yog qhov kev tiv thaiv yog qhov kev tiv thaiv.
Cov txiaj ntsig ib puag ncig
Nyob rau hauv hnub no lub ntiaj teb no eco-nco ntsoov ntiaj teb, bopp shines nrog nws ib puag ncig cov peev txheej:
Rov ua dua tshiab : BOPP poob raws li kev rov ua dua siab code # 5 (PP), ua rau nws dav rov ua dua tshiab.
Kev nthuav dav : Raug txawv nyob ib ncig ntawm 0.90-0.92 g / cm³ no ua rau txo qis kev thauj mus los.
Kev siv hluav taws xob-ua tau zoo heev : kev tsim cov txheej txheem kev lag luam tsawg dua lub zog piv rau qee cov ntaub ntawv.
Lub rooj sib tham ntawm kev mus ncig sab Europe tau tshawb fawb pom tias cov yeeb yaj kiab ntawm cov yeeb yaj kiab tau muaj 40% qis dua cov kab mob carbon ntxiv rau cov tsiaj sib npaug.
Economic Zoo
BOPP muaj cov nqi tseem ceeb nqi vim nws cov txiaj ntsig siab. Nws qhov ntom ntawm kwv yees li 0.90-0.92 g / cm³s nyob rau hauv ntau zaj duab xis ib qho phaus phaus piv rau polyester (ceev) ~ 1.4 g / cm³). Qhov no txhais tau cov nqi txuag hauv ob qho kev siv nyiaj txiag thiab kev thauj mus los.
Kev lees paub thoob ntiaj teb Kev Lag Luam yooj yim thoob ntiaj teb thiab kev xa khoom. Raws li cov ntaub ntawv kev lag luam, cov Asia-Pacific Tebchaws Dominates cov kev ua lag luam Bopp, tus account rau ntau dua 60% ntawm lub ntiaj teb ntau lawm.
Versatility
Bopp lub versatility yog pom tseeb nyob rau hauv nws ntau ntawm muaj ua tiav:
| tiav yam | cov gloss units (45 °) | cov ntawv thov tshwj xeeb |
| Siab heev | > 90 | Khoom Kim Heev Ntim |
| Lub hom phiaj | 70-90 | Lub Hom Phiaj Dav |
| Matte | <br 40 | Tsis-Txiaj Laab Ntawv |
| Nyob ntsiag to | 40-70 | Mos-kov cov teebmeem |
Qhov no ntau yam ntsuas rau muaj kev ua kom zoo nkauj thiab kev ua haujlwm xav tau thoob plaws kev lag luam, los ntawm cov zaub mov ntim khoom hauv cov tshuaj pleev ib ce kom zoo.
Cov Nyiaj Tau Los
Bopp excels nyob rau hauv ntau yam kev ua tau zoo:
| kev ua | cov nyiaj pab | tau zoo ntawm |
