Zaj movie Vs Ntxawm Tsab

Cov txheej txheem cua tshuab yog zoo ib yam li inflating lub zais pa loj.

Cov txheej txheem cam khwb cia zoo li cov dej tsaws tsag uas ntws los.

• Txheej txheem: Lub molten polymer tawm hauv lub tiaj T- tuag (slit tuag) thiab ntws mus rau hauv qab zoo li daim ntaub.

• Txias: Cov yaj tuaj rau hauv tam sim ntawd nrog ib qho loj, rotating chill yob, qhov chaw uas nws txias sai heev thiab solidified los ntawm qhov qis - kub ntawm cov hlau nto.

• Haul-tawm: Cov zaj duab xis txias yog txiav, ncab rau hauv lub tshuab kev taw qhia, thiab thaum kawg raug mob rau hauv yob.

[Cov ntsiab lus]: T- tuag; txias- yob quenching; Feem ntau uniaxial stretching.

• Winner: Cast film

Lub hauv paus ntsiab lus: Cam khwb cia zaj duab xis yog ceev ceev quenched los ntawm txias yob, uas ho suppresses polymer crystallization thiab ua rau zoo crystalline lug.

Kev ua tau zoo: pob tshab zoo heev, tsis muaj haze, thiab siab gloss. CPP cam khwb cia zaj duab xis zoo li crystal ntshiab.

• Blown film:

Cua txias kuj qeeb, tso cai rau ntau lub sij hawm rau crystallization thiab tsim ntawm loj crystalline lug, uas ua rau kom lub teeb tawg.

Kev ua tau zoo: hawb pob ntau dua thiab muaj qhov pom tseeb, txawm hais tias cov dej siab tshaj -cov tshuab cua tshuab cua txias tau txhim kho kev ua haujlwm kho qhov muag hauv xyoo tas los no.

• Winner: Blown Film (Ntau yam khoom sib npaug)

Lub hauv paus ntsiab lus: Thaum lub sij hawm tshuab cua tshuab, zaj duab xis yog stretched nyob rau hauv ob qho tib si lub tshuab kev taw qhia thiab transverse kev taw qhia.

Kev ua tau zoo: Lub zog yog qhov sib npaug ntawm ob qho kev qhia, nrog zoo toughness thiab siab puncture kuj. Qhov no yog vim li cas cua tshuab yog dav siv rau lub khw muag khoom lub hnab, vim nws tsis tshua muaj kua muag thaum nqa cov khoom hnyav.

• Cast film (kev taw qhia tsis muaj zog)

Lub hauv paus ntsiab lus: Stretching tshwm sim feem ntau nyob rau hauv lub tshuab kev taw qhia, nrog tsawg tsawg transverse orientation.

Kev ua tau zoo: Lub molecular orientation yog kev taw qhia siab heev. Thaum lub zog tensile nyob rau hauv lub tshuab kev taw qhia tau txais, transverse kua muag kuj tsis zoo. Thaum ib daim ntawv me me, cov yeeb yaj kiab zoo li tawg ncaj qha (zoo ib yam li daim kab xev nplaum).

• Winner: Cast Film

Cov ntaub ntawv: Thickness kam rau ua feem ntau tuaj yeem tswj tau li ntawm ± 1.5% txog 3%.

Qhov zoo: Zoo heev flatness, ua rau nws zoo tagnrho rau siab - ceev printing thiab precision txheej.

• Tshuab zaj duab xis

Cov ntaub ntawv: Thickness kam rau ua feem ntau yog nyob ib ncig ntawm ± 5% mus rau 10%, txawm tias rotating tuag.

Qhov tsis zoo: Cov thickness tsis sib xws tuaj yeem ua rau cov tuab tuab tuab thaum winding, cuam tshuam tsis zoo tom qab lamination zoo.

Qhov zoo me ntsis: Blown Film

Blown zaj duab xis yog tsim nyog rau kev koom ua ke siab - cov ntaub ntawv thaiv xws li PA thiab EVOH los ntawm ntau txheej co-extrusion (piv txwv li, 5-, 7-, lossis 9-txheej qauv). Cov cuab yeej siv cuab yeej cuab tam yog qis dua, thiab cov qauv tsim yog hloov tau yooj yim dua.

• CPP (Cast Polypropylene): Cov cua sov sab hauv- sealing txheej rau ntim khoom noj (xws li, biscuit thiab khob cij), yuav tsum tau siab pob tshab thiab zoo tawv.

• Stretch zaj duab xis: Siv rau pallet wrapping, tau txais txiaj ntsig los ntawm kev ua haujlwm siab ceev ntawm cov kab nrum (txog 500 m / min lossis ntau dua).

• Cov khoom siv tu cev: Cov ntaub qhwv cov ntaub npuag thiab cov khoom siv huv huv, qhov chaw mos thiab kev nplij siab (xws li, CPE) yog qhov tseem ceeb.

• Aluminized substrates: Cov ntawv thov uas yuav tsum tau flatness heev, qhov cam khwb cia zaj duab xis yog qhov kev xaiv.

• Kev ntim khoom dav dav: Lub hnab ntim khoom, T- lub hnab tsho, thiab cov hnab khib nyiab (tsuas yog PE), yuav tsum muaj qhov tawv thiab tus nqi qis.

• Agricultural films: Mulch films thiab greenhouse films, where blown film can easily achieve ultra-wide widths.

• Hnyav - lub luag haujlwm ntim: Cov hnab ntim chiv thiab hnab nplej (FFS), yuav tsum muaj kev cuam tshuam thiab kev tiv thaiv.

• Thaum tshav kub kub-shrink films: Siv biaxial orientation nco nco kom ntswj ib ncig ntawm cov khoom thaum rhuab.

• Yog tias cov khoom tso tawm - taw qhia (piv txwv li, paj, cov ntaub ntawv zoo nkauj, pob tshab qhov rais ntim) thiab xav tau kom meej meej, xaiv cov yeeb yaj kiab cam khwb cia.

• Yog tias cov khoom hnyav, nruj, lossis ntse -edged (piv txwv li, khov nqaij, kho vajtse), thiab puncture kuj tseem ceeb heev, xaiv zaj duab xis tshuab.

• Siab-kev ceev luam ntawv lossis txheej txheej: Lub thickness superior uniformity ntawm cam khwb cia zaj duab xis ho txhim kho yield thiab txheej txheem stability.

• IBag ua: Ob qho yeeb yaj kiab yog tsim rau cov cua sov yooj yim-cov hnab kaw; Txawm li cas los xij, rau cov qauv hauv lub hnab nyuaj, qhov kev pheej hmoo ntawm kev hloov pauv hauv cov yeeb yaj kiab cam khwb cia yuav tsum tau ua tib zoo soj ntsuam.

• Cam khwb cia zaj duab xis: Cov cuab yeej siv nyiaj ntau dua thiab kev siv lub zog, tab sis cov zis siab thiab ua haujlwm tau zoo, tsim nyog rau loj - ntim ntau lawm.

• Blown film: Cov khoom siv qis dua thiab hloov tau yooj yim dua hauv cov kev qhia tshwj xeeb, haum rau me me - mus rau nruab nrab - ntim, ntau- khoom tsim.
