Umbuzo wokuthintela ukufuma

Kubasebenzi bokupakisha abakhetha umtya okanye imathiriyeli yefilimu, ukusebenza kwesithintelo sokufuma kunokuba yingqwalasela ebalulekileyo. Iimveliso ezigcinwe kwindawo ezifumileyo, ezithunyelwa kwiindawo ngemozulu, okanye zipakishwe ngeempahla ezingevani nokufuma zifuna ukupakishwa okugcina ukufuma ngaphandle. Oku kuphakamisa umbuzo oqhelekileyo: ngaba i-PP strap ingcono kune-PET njengesithintelo sokufuma? Xa kuthelekiswa amazinga okuhambisa umphunga wamanzi, idatha ibonisa ukuba ifilimu ye-polypropylene (OPP) ibonelela malunga namaxesha angama-5.4 angcono ukusebenza komqobo wokufuma kune-PET yobunzima obulinganayo. Ukuqonda lo mahluko wezinto eziphathekayo kunceda iingcali zokuthenga zikhethe izinto ezifanelekileyo zokupakisha kwizicelo zabo ezithile.

Kwi- Jushuo Packaging , sihlala sifumana lo mbuzo kubathengi abavavanyayo Umtya wePP wezicelo apho ukubonakaliswa komswakama kuyinkxalabo. Idatha yethu yokuvelisa iqinisekisa ukuba i-PP strap's inherent ukumerika ukumelana-isiphumo se-non-polar ye-molecular structure-yenza ifanelekele ukugcinwa kwangaphandle, ukulima, kunye nezicelo zokusingqongileyo.

1. Isithintelo sokufuma: Idatha

1.1 Uthelekiso lweNtsebenzo yesithintelo

Idatha yovavanyo epapashiweyo inika impendulo ecacileyo kumbuzo wothintelo lokufuma. Ngokovavanyo oluzimeleyo oluthelekisa i-PET kunye neefilimu ze-polypropylene (OPP) ezijonge ubukhulu obufanayo, i-BOPP ibonise ukusebenza okuphezulu kakhulu komqobo womphunga wamanzi :

Izinto eziphathekayo	Izinga loThutho loMphunga waManzi (WVTR)	iGanga loThutho lwe-Oxygen (OTR)
Ifilimu yePET	18.07 g/(m²·24h)	28.01 cm³/(m²·24h·0.1MPa)
Ifilimu yeBOPP	3.36 g/(m²·24h)	651.60 cm³/(m²·24h·0.1MPa)

Idatha ibonisa izinga lokuhanjiswa komphunga wamanzi we-BOPP malunga namaxesha angama-5.4 ngaphantsi kune-PET's, ebonisa ngokucacileyo ukusebenza okuphezulu komqobo wokufuma. Imithombo yemizi-mveliso iqinisekisa ukuba isithintelo sokunyakama se-polypropylene simalunga namaxesha amathathu angcono kune-PET . Umahluko kwiipropathi zokuthintela umphunga wamanzi zibalelwa kumahluko kwi-polymer molecular polarity .

1.2 Kutheni iPP InoMthintelo wokufuma oNgcono

Isithintelo somswakama esiphezulu sePP xa kuthelekiswa ne-PET sinxulumene ne-polymer chemistry. I-PP yipolymer ye-hydrocarbon engekho-polar enobudlelwane obuphantsi beemolekyuli zamanzi, okukhokelela ekungeneni kokufuma okuphantsi. I-PET iqulethe amaqela e-ester ane-polarity ephezulu, edala iindawo ezininzi zokusebenzisana ukuze iimolekyuli zamanzi zidlule kwisakhiwo sepolymer. .

Ngokupakishwa koncwadi lwesayensi, ukusebenza komqobo womphunga wamanzi we-polyolefins njenge-PP ungaphezulu ngokwendalo kunolo lweepolyester ezinjenge-PET ngenxa yendalo yazo ye-hydrophobic kunye nomthamo ophantsi wasimahla wokusasazwa kwemolekyuli yamanzi.

2. UMfanekiso oGqibeleleyo wesithintelo

2.1 Isithintelo se-Oxygen: Amandla e-PET

Ngelixa i-PP igqwesa njengesithintelo sokufuma, i-PET ibonelela ngenzuzo eyahlukileyo: umqobo ophakamileyo weoksijini. Idatha yovavanyo olufanayo ibonisa ukuba izinga lokuhanjiswa kwe-oxygen ye-PET limalunga namaxesha angama-23 ngaphantsi kune-BOPP's . Oku kwenza i-PET ibe yinto ekhethwayo kwizicelo apho i-oxygen ingress iyona nto ixhalabisayo-efana nokupakishwa kokutya okudinga ixesha elide leshelufu.

2.2 Isishwankathelo sesithintelo

Property	PP (BOPP)	PET	Advantage
Isithintelo sokufuma (WVTR)	Kugqwesileyo (~3.36 g/m²·24h)	Phakathi (~18.07 g/m²·24h)	PP (5.4× ngcono)
Isithintelo seOxygen (OTR)	Imbi (~651.60 cm³/m²·24h)	Kugqwesileyo (~28.01 cm³/m²·24h)	I-PET (23× ngcono)

Olu lwalamano oluphambeneyo phakathi komswakama kunye nomqobo we-oksijeni yinto eyaziwayo kwisayensi yokupakisha i-polymer-izinto ezahlukeneyo zigqwesa kwiindidi ezahlukeneyo zokukhusela umqobo.

3. Iziphumo zokuKhetha umtya wePP

3.1 Xa uMthintelo wokufuma ubalulekile ekuXhwetyweni

Kwiinkqubo ezininzi ze-PP zomtya, umqobo wokufuma ayisiyonto iphambili yokukhetha. Ukubopha ngokuqhelekileyo kusetyenziselwa ukukhusela imithwalo kunokubonelela ngokupakisha okukhuselekileyo. Nangona kunjalo, kwiimeko ezithile, ukuxhathisa ukufuma kuyaba yimfuneko:

Ukugcinwa kwangaphandle: Ukumelana nokufuma kwe-PP strap kunceda ukugcina ukusebenza kwiimeko ezifumileyo okanye ezimanzi
Ukusetyenziswa kwekhonkco elibandayo: Ukufuma okuvela kwi-condensation kunokuchaphazela ukunyanzeliswa komtya kunye nokuthembeka
Ukupakishwa kwezolimo: Ihayi, umqhaphu, kunye nezinye iimveliso zezolimo zidla ngokugcinwa ngaphandle

Umtya we-PP weJushuo Packaging unikezela ukuxhathisa ukufuma okungokwemvelo njengenxalenye yezinto zayo eziphathekayo, okwenza ukuba ilungele ezi zicelo zinzima.

3.2 Isikhokelo soKhetho lweMathiriyeli

Ukupakisha iingcali zokukhetha izixhobo zokubopha:

Imfuneko	eCetyisiweyo	Isizathu seMaterial
Ukhuseleko lokufuma kwiimpahla ezipakishiweyo	Umtya wePP (ukuba ubophe kuphela) okanye ifilimu yePP	Umqobo ophakamileyo wokufuma
Iimveliso ezingeva ngeoksijini (ukutya, amayeza)	Umtya wePET okanye ifilimu yePET	Umqobo ophezulu weoksijini
Ukhuseleko lomthwalo onzima kunye nokugcinwa kwangaphandle	Umtya wePP okanye umtya wePET	Zombini zibonelela ngokumelana nokufuma okuhle

Isishwankathelo

Ngaba i-PP ingcono kune-PET njengesithintelo sokufuma? Idatha iqinisekisa: ewe, iPP ibonelela ngokusebenza okuphezulu komqobo wokufuma. Izinga lokuhanjiswa komphunga wamanzi wefilimu yeBOPP limalunga namaxesha angama-5.4 ngaphantsi kwe-PET, nto leyo eyenza iPP ibe ngumnqobi ocacileyo wezicelo ezifuna ukhuseleko lokufuma. Nangona kunjalo, umfanekiso wesithintelo une-nuanced ngakumbi: I-PET igqwesa njengesithintelo se-oksijeni, kunye nokusebenza malunga namaxesha angama-23 angcono kune-PP.

Ukusetyenziswa komtya, isithintelo sokufuma ayisiyiyo eyona khrayitheriya yokukhetha, kodwa ukuxhathisa okungokwemvelo kwePP-isiphumo se-non-polar hydrocarbon structure-yenza ilungele ukugcinwa kwangaphandle, ezolimo, kunye nezicelo zendalo ezifumileyo. Xa ukhetha phakathi kwe-PP kunye ne-PET strap, qwalasela iimfuno ezipheleleyo zesicelo: ukubonakaliswa komswakama, ubunzima bomthwalo, kunye nokuba umqobo we-oksijeni nawo uqwalaselwe.
