Qhov siab tshaj plaws ntawm cov yas ntim zaj duab xis (tshuab zaj duab xis) yog nyob ntawm qhov tshwj xeeb ntawm kev tuag, tshuab zaj duab xis tshuab teeb tsa, hom khoom, thiab kev tswj cov txheej txheem.
1. Common Blown Film Width Range (raws li cov khoom tiav "flat width")
Yam tsawg kawg nkaus dav: 50-100 mm
Tsis tu ncua: 200-1200 mm
Qhov dav dav (cov tshuab loj tsis tu ncua): 1500-2500 mm
Qhov no suav nrog feem ntau cov hnab ntim khoom yas:
Cov hnab courier, hnab ris tsho, hnab khib nyiab, hnab zaub mov, hnab pallet npog, thiab lwm yam.
Ultra-wide blown film (cov khoom loj lossis customized)
Qhov siab tshaj plaws dav: 3000-4000 mm
Cuam tshuam unfolded ncig: 6000-8000 mm
Qhov no feem ntau yog siv rau:
Cov hnab loj loj
Pallet npog
Kev tsim kho / kev ua liaj ua teb
Hnyav- lub luag haujlwm ntim cov hnab ntim khoom
2. Nkag siab qhov siab tshaj plaws ntawm qhov "tuag txoj kab uas hla" (ntau tshaj lij)
Simple formula reference:
Pav dav dav ≈ Die txoj kab uas hla × Tshuab- nce piv ÷ 2
3. Kev cuam tshuam ntawm cov ntaub ntawv ntawm qhov siab tshaj plaws (tseem ceeb heev)
Cov khoom sib txawv muaj qhov sib txawv tswj tau qhov dav txwv:
HDPE
Haum rau qhov dav dav
Nyias, tawv, ruaj khov
Feem ntau siv rau cov hnab khib nyiab, hnab courier
LDPE / LLDPE
Zoo toughness
Ultra- qhov dav dav yuav tsum tau tswj cov txheej txheem ntau dua
Peb- txheej co-extrusion / ABA
Zoo dua dav stability
Ntxiv rau qhov loj -qhov loj, siab- cov khoom xav tau
4. Kev tsim khoom tiag tiag kuj raug txwv los ntawm cov xwm txheej no
Txawm hais tias qhov tuag tuaj yeem tsim qhov dav, nws tsis tau txhais hais tias kev ruaj khov loj tuaj yeem ua tau. Lwm yam muaj xws li:
Tshuab zaj duab xis tshuab traction qhov siab
Cov cua txias txias efficiency
Flattening ncej thiab winding dav
Thickness yuav tsum tau (thinner films yog nyuaj rau tswj dav)
Txawm tias tom qab lub hnab ua, xuas nrig ntaus, thiab sealing yuav tsum tau
Ntau lub chaw tsim khoom tawm 10-20% kev nyab xeeb ntawm qhov "theoretical siab tshaj plaws dav"
5. Kev txiav txim siab seb cov khoom puas tuaj yeem tsim tau ib qho me me
Tsuas yog 3 cov ntaub ntawv no tsuas yog xav tau:
Dab tsi yog qhov tuag diam?
Ib txheej / ABA / Peb- txheej co-extrusion
Yuav tsum tau thickness ntau (micron)
