Indlela Izinsiza Zokucubungula I-Polymer Ezingenawo i-PFAS Ezithuthukisa Ngayo Ibhalansi Yokugeleza Kwezingqimba, Ukuqina Kokufa, kanye Nekhwalithi Yefilimu ku-Extrusion Yama-Multilayer

Isingeniso

Ubuchwepheshe be-multilayer co-extrusion buvumela abakhiqizi ukuhlanganisa ama-polymer ahlukene abe amafilimu asebenza kahle kakhulu anezakhiwo ezithuthukisiwe zokuvimbela, amandla okusebenza, ukusebenza, kanye nokusebenza kahle kwezindleko. Busetshenziswa kabanzi kumafilimu okupakisha aguquguqukayo, ukupakisha ukudla, amafilimu okuvimbela, kanye nezicelo zamafilimu ezimboni.

Kodwa-ke, njengoba izakhiwo zezendlalelo eziningi ziba yinkimbinkimbi kakhulu futhi isivinini sokukhiqiza sanda, abakhiqizi bavame ukubhekana nezinselele zokukhipha njengokungalingani kokuncibilika kwezendlalelo kuya kwezendlalelo, ukuphazamiseka kokugeleza kwe-interfacial, ukwakheka kwe-die, kanye nokwanda komswakama wefilimu. Lezi zinkinga zingathinta ukufana kwezendlalelo, ukubukeka kwendawo, ukuzinza kokukhiqiza, kanye nokusebenza kokuguqula phansi.

Ngokwesiko, izinsiza zokucubungula ezisekelwe ku-fluoropolymer (ama-PPA) ziye zasetshenziswa ukuthuthukisa ukuzinza kokukhipha kanye nokunciphisa amaphutha ahlobene nokuncibilika. Kodwa-ke, ukunakwa okwandayo kokulawula ezintweni ze-PFAS kusheshisa isidingo sezixazululo zokucubungula i-polymer ezingenayo i-PFAS kanye ne-fluorine.

Uchungechunge lwe-SILIKE SILIMER lwe-PFAS-Free Polymer Processing Aids (PPAS)) ukuhlinzeka ngendlela entsha engena-fluorine yokuthuthukisa ibhalansi yokugeleza kokuncibilika, ukuthuthukisa ukuzinza kwe-die, ukunciphisa amaphutha okukhipha, nokusekela ukukhiqizwa kwamafilimu amaningi okusimeme ngaphandle kokubeka engcupheni izinqubo ezingezansi njengokuphrinta, i-lamination, kanye nokuvalwa kokushisa.

Lesi sihloko siqokomisa amaphutha avamile e-multilayer co-extrusion, sichaza izimbangela zawo, sibukeza izinselele zezixazululo zokucubungula ezivamile, futhi sihlola ezinye izindlela ezingenayo i-PFAS ukusiza abakhiqizi ukuthi bafeze izinqubo zokukhipha amafilimu amaningi ezisebenza kahle, ezisimeme, nezinwebekayo.

Yiziphi Iziphambeko Ezivamile Ku-Multilayer Co-Extrusion?

Ukwehlukaniswa kwe-multilayer co-extrusion kudinga ukuncibilika kwe-polymer okuningi ukuze kugeleze ndawonye nge-die eyodwa ngenkathi kugcinwa izixhumanisi ezizinzile kanye nokulawulwa okunembile kokujiya kwesendlalelo. Umehluko ezimpahleni ze-polymer ungadala kalula ukungazinzi kokucubungula.

Amaphutha avamile okukhipha izinto ezingqimba eziningi ahlanganisa:

• Ukusatshalaliswa kwezingqimba ezingalingani

• Ukwehluka kobukhulu besendlalelo

• Ukungazinzi kokugeleza kobuso

• Ukuqhekeka okuncibilikayo kanye nokukhubazeka kobuso

• Ukwakheka kwama-die ngesikhathi sokukhiqiza okuqhubekayo

• Ukwanda komswakama wefilimu kanye nekhwalithi yokukhanya enciphile

• Ukuphazamiseka njalo kokukhiqiza kokuhlanza izitini

Ukuqonda izimbangela eziyinhloko zalezi ziphambeko kuyisinyathelo sokuqala sokuthuthukisa ukusebenza kwe-extrusion.

Izimbangela Eziyinhloko Zezinkinga Zokunwetshwa Kwe-Multilayer Co-Extrusion

1. Ukungafani Kokubonakala Phakathi Kwezingqimba Ezihlukene Ze-Polymer

Enye yezinselele ezinkulu ekukhishweni kwezingqimba eziningi umehluko ekuqineni kokuncibilika phakathi kwezingqimba ezahlukene ze-polymer.

Izakhiwo ezijwayelekile ezinezingqimba eziningi zingafaka inhlanganisela yalokhu okulandelayo:

• I-Polyethylene (PE)

• I-Polypropylene (PP)

• Utshwala lwe-ethylene vinyl (EVOH)

• I-Polyamide (PA)

• Izendlalelo zethayi elinamathelayo

I-polymer ngayinye inezinhlobo ezahlukene:
