PBAT Hnab Ua Tshuab Thaum tshav kub kub sealing, txiav thiab pawg PBAT / PLA, PBAT / starch thiab PBAT / CaCO3 zaj duab xis thiab sib tov rau hauv cov hnab ntim khoom tiav. PBAT yog biodegradable aliphatic - paj rwb polyester. Lub melting point yog 110-115 degree, lub pob txha elongation yog ntau tshaj 300%, thiab qhov ceev yog li ntawm 1.2-1.3 g / cm3. Nws toughness thiab saj zawg zog ua rau nws lug siv nyob rau hauv cov khoom siv hluavtaws. European Bioplastics tau tshaj tawm tias PBAT suav rau feem tseem ceeb ntawm lub ntiaj teb bioplastic tsim muaj peev xwm. Ib leeg- siv cov kev txwv lub hnab thiab cov kev cai ntim cov khoom ntim tau txhawb nqa qhov kev thov no hauv ntau lub khw.
BAT raws li cov khoom siv yooj yim - cov khoom ntawm kev tsim mechanism tsim
PBAT muaj kev ua haujlwm sib txawv los ntawm cov tshuaj polyethylene. Cov kev sib txawv no muaj kev cuam tshuam ncaj qha rau kev tsim tshuab:
- Melting kub: 110-115 degree, ze rau LDPE. PBAT pib degrade ntawm li 200 degree. Qhov no muab cov khoom siv tsawg dua rau kev ua haujlwm.
- Melt flow index: 2-5 g / 10 mins ntawm 190℃/ 2.16 kg. Qhov no yuav tsum muaj qhov tsim nyog drawdown ratios thiab ntsia hlau tsim thaum lub sij hawm extrusion zaj duab xis.
- Fracture elongation: 300% -700% rau PBAT zaj duab xis ntshiab. Qhov ntawd siab dua ntau cov qhab nia PE. Zaj duab xis yog elongated nyob rau hauv cov xwm txheej nruj.
- Sealing kub: 90-130 degree, sealing zoo li ntawm 15-25 degree.
Biodegradability: PBAT sib xyaw ua tau raws li cov kev xav tau ntawm composting compostability ntawm ASTM D6400 thiab EN 13432 raws li kev tswj hwm kev lag luam composting.
Cov yam ntxwv no tso cai rau PBAT Lub Hnab Ua Tshuab ua haujlwm ntawm qhov kub zoo ib yam li PE raj. PBAT, txawm li cas los xij, muaj lub foob nqaim dua thiab softer, elastic dua zaj duab xis. nruj system yuav tsum tau nrog nws ntau dua stretchability. Qhov kev nruj nruj yuav qis dua li PE kab. Servo tsav coils nrog cov lus tawm tswv yim los ntawm kaw- lub voj voog thauj khoom tuaj yeem pab tswj cov yeeb yaj kiab ruaj khov thaum txiav thiab sib khi.
Cov ntaub ntawv tseem ceeb ua tiav
Lub tshuab tuav plaub yam khoom. Txhua hom yuav tsum tau ua cov txheej txheem sib txawv.
Ntshiab PBAT Film
Mono- txheej PBAT zaj duab xis feem ntau yog 20-80 microns tuab. Nws yog ib qho ntawm PBAT yooj yim dua los ua. Nws tuaj yeem raug kaw ntawm 100-130℃nrog lub siab ntawm 0.2-0.5 MPa siab thiab lub sijhawm nyob ntawm 0.3-0.6 vib nas this. Ntshiab PBAT tsim cov hnab mos, hloov tau yooj yim. Cov hnab no tuaj yeem siv los tsim cov ntim khoom, hnab ris tsho, thiab cov hnab khoom hluavtaws. Txij li cov zaj duab xis muaj qhov elongation siab, lub loosening nro yuav tsum tau khaws cia hauv qab 30N, uas yuav pab tiv thaiv cov zaj duab xis los ntawm stretching thaum nws dhau los ntawm lub tshuab.
PBAT/PLA sib tov
PBAT / PLA yog siv dav hauv kev lag luam ntim khoom siv. PBAT thiab PLA tuaj yeem sib xyaw ntawm 40/60 rau 80/20 piv. Ib qho 60/40 PBAT / PLA sib xyaw yog qhov feem ntau. PLA ntxiv hardness, printability thiab kub kuj. PBAT ntxiv qhov hloov tau yooj yim thiab cuam tshuam tsis kam. Lub melting point ntawm qhov sib tov yog hais txog 130-160 degree, nyob ntawm tus nqi ntawm PLA. Nws cov qhov rais airtight kuj nqaim, txog 10-15 degree. PBAT Lub Hnab Ua Tshuab khiav qhov sib tov yuav tsum tau tswj qhov kub thiab txias, feem ntau nyob ib ncig ntawm ± 2 degree. Sealing siab tuaj yeem siab dua me ntsis, txog 0.3-0.6 MPa, uas pab ua kom lub zog ruaj khov. Lub elongation ntawm qhov sib tov yog qis dua PBAT ntshiab, feem ntau yog li 100-300%. Qhov no coj cov teeb tsa nruj dua rau cov uas siv hauv PE zaj duab xis.
PBAT/Starch Blends
Cov hmoov txhuv nplej siab feem ntau yog siv los ua tus nqi qis - tus nqi muab tub lim hauv PBAT cov qauv. Cov ntsiab lus ntawm starch feem ntau yog li ntawm 10% mus rau 30%. Nws tuaj yeem cuam tshuam rau ob qho tib si tshuab kev ua haujlwm thiab lub hnab ntim khoom. Cov hmoov txhuv nplej siab tsub kom qhov txhav thiab nto roughness ntawm zaj duab xis. Nws kuj tuaj yeem ua rau zaj duab xis rhiab heev rau cov dej noo. Lub sealing kub feem ntau yog li ntawm 120-140 degree. Cov hmoov txhuv nplej siab tuaj yeem xav tau lub sijhawm nyob ntev dua li PBAT ntshiab. Qhov no ua kom tiav sealing vim tias muaj peev xwm kub ntau dua ntawm cov hmoov txhuv nplej siab. Cov formulations no kuj zoo li muaj ntau dua coefficient ntawm kev sib txhuam, uas tuaj yeem cuam tshuam li cas cov yeeb yaj kiab txav mus los ntawm qhov tsim.
PBAT/CaCO3 Compounds
Thaum lub sij hawm winding, 20-50% Calcium carbonate tuaj yeem muab ntxiv los txo cov nqi resin, nce opacity, thiab txhim kho zaj duab xis flatness. Cov ntxhia dej -filled zaj duab xis yog ib qho nyuaj, tsis tshua muaj elastic thiab ntau abrasive dua li PBAT ntshiab. Cov tshuab ua haujlwm nrog cov ntsiab lus CaCO3 siab tuaj yeem siv cov txiav tawv tawv, xws li D2 cuab yeej steel lossis carbide-tipped npoo. Hnav-cov ntaub thaiv qhov chaw tiv taus kuj tuaj yeem pab txo qhov hnav thiab tsim kua muag. Sealing kub tuaj yeem nce li 5-10℃vim qhov thermal loj ntawm cov ntxhia. Cov nqi ntau lawm kuj tuaj yeem raug txo los ntawm 10-15% vim tias cov yeeb yaj kiab qeeb hloov cov cua sov thaum lub sijhawm sib khi thiab txias.

Cov ntaub ntawv ua tiav PBAT Lub Hnab Ua Tshuab yuav tsum ua kom tau raws li cov txheej txheem kev ruaj ntseg hluavtaws thaum muag raws li cov khoom siv compostable:
- ASTM D6400 - US Standard for Synthetic Plastics. Nws muab rau decomposition thiab biodegradation yuav tsum tau nyob rau hauv kev tswj industrial composting tej yam kev mob.
- TS EN 13432-European Synthetic Ntim Cov Qauv Nws suav nrog kev tawg, biodegradation thiab kev txwv rau qee yam hlau hnyav thiab lwm yam khoom.
- ISO 14855-1 - Kev ntsuas txoj hauv kev ntsuas biodegradation ntawm plastics nyob rau hauv kev tswj cov composting. Cov ntaub ntawv sim tuaj yeem txhawb nqa cov qauv kev ntsuas kev sib xyaw ua ke raws li tus qauv tsim nyog.
- EU PPWR - Cov Txheej Txheem Ntim thiab Ntim Cov Khoom Pov Tseg (EU) 2024/1781 tau teeb tsa cov kev xav tau rau kev ntim khoom, txo pov tseg, rov ua dua tshiab thiab muaj pes tsawg leeg rau qee daim ntawv thov ntim.
Grand View Research tej yaam num uas lub ntiaj teb no biodegradable plastics lag luam yuav loj hlob mus ntxiv. PBAT thiab PLA tau siv dav hauv cov khoom siv hluavtaws. Cov kev ua lag luam thiab kev tswj hwm kev hloov pauv no tau nce qhov kev thov rau cov cuab yeej muaj peev xwm ua cov ntaub ntawv pov thawj compostable thaum tuav cov nqi sib tw.
F A Q
Lub hnab PBAT puas tuaj yeem ua cov PE zaj duab xis ib txwm?
Yog lawm. Lub tshuab qauv yooj yim zoo ib yam. Nws suav nrog kev tso tawm, ntug guiding, txiav, sealing thiab stacking. PE muaj qhov kub thiab txias me ntsis thiab kev ua haujlwm dav dua. Txawm li cas los xij, kev siv tib cov kab ntau lawm rau cov khoom siv hluavtaws thiab cov khoom siv sib xws tuaj yeem ua rau hla - paug. Qhov no tuaj yeem cuam tshuam txog kev thov compostability. Cov hloov pauv rau kev tsim cov hnab ntim cov ntaub ntawv pov thawj feem ntau siv cov kab mob siab rau PBAT- cov ntaub ntawv raws li.
Yuav ua li cas noo noo rhiab heev cuam tshuam rau PBAT / starch zaj duab xis thaum lub hnab ntim khoom?
PBAT nws tus kheej nqus dej tsawg dua PLA. Cov hmoov txhuv nplej siab-raws li cov khoom sib xyaw absorbs noo noo yooj yim dua. Cov av noo ntau dhau nyob rau hauv qhov chaw kaw ua rau qhov pores, npuas thiab tsis muaj zog sealing. zaj duab xis yob yog khaws cia ntawm qhov kub ntawm 20-25℃nrog txheeb ze av noo qis dua 50%. Cov hmoov txhuv nplej siab- nplua nuj formulations kuj tseem yuav xav tau ua ntej- ziab lossis tswj cia ua ntej ntim.
Lub neej txee ntawm PBAT zaj duab xis ua ntej ntim khoom yog dab tsi?
PBAT zaj duab xis ntshiab yog khaws cia nyob rau hauv lub foob, txias thiab qhuav 6-12 lub hlis thiab tswj kev ua haujlwm zoo. Vim yog qhov hloov pauv noo noo nqus ntawm cov hmoov txhuv nplej siab, lub sij hawm cia ntawm cov hmoov txhuv nplej siab -blended zaj duab xis yog luv, txog 3 mus rau 6 lub hlis. Ntev - lub sij hawm cia yuav txo tau lub zog foob thiab ua rau kom lub hnab tsis kam thiab cov khoom pov tseg.
Cov khoom siv ntau yam ntawm PBAT Hnab Ua Tshuab cuam tshuam rau nws daim ntawv thov hauv kev ntim khoom sib xyaw. Kev sib xyaw ntawm Ntshiab PBAT zaj duab xis thiab PLA, cov hmoov txhuv nplej siab, lossis cov ntxhia hauv cov khoom siv yuav tsum muaj qhov sib txawv ntawm qhov sib txawv, cov yeeb yaj kiab nro, txiav, thiab tswj cov dej noo. Daim ntawv qhia-raws li kev teeb tsa ua kom yooj yim hloov cov ntaub ntawv. Servo- cov tshuab tsav tuaj yeem hloov tau li ntawm 10-15 feeb, nyob ntawm seb hom lub hnab thiab qhov tsim ntawm lub tshuab.
Rau cov tuam txhab nrhiav ISO 9001: 2015 thiab CE daim ntawv pov thawj rau cov khoom ntim khoom, cnzhuxinmachine.com muaj cov cuab yeej txhawb nqa los ntawm ntau tshaj 30 xyoo ntawm kev ua haujlwm engineering.
