Izinsiza Zokucubungula Ama-Polymer Zamahhala ze-PFAS (PPA) zokukhishwa kwefilimu ye-PE

Ukushintshwa kwe-Fluoropolymer Kokucubungula Amafilimu Okuzinzile, Okusheshayo

Yiziphi izinkinga ezivimbela ukukhishwa kwefilimu ye-PE namuhla?

Ukukhishwa kwefilimu ye-Polyethylene (PE) kusetshenziswa i-LLDPE, i-HDPE, kanye ne-MLLDPE kuvame ukukhawulelwa ukuqhekeka kokuncibilika, ukwakheka kwesikhumba se-sharks, kanye nokugeleza kokufa okungazinzile ngaphansi kwezimo zokuphuma okuphezulu.

Lezi ziphambeko zibangelwa ukungazinzile kokungqubuzana phakathi kokuncibilika kwe-polymer kanye nobuso bensimbi, ikakhulukazi ngaphansi kokucindezeleka okukhulu kwe-shear.

Ama-PPA asekelwe ku-Fluoropolymer abelokhu esetshenziswa ekuqiniseni ukucubungula, kodwa ukwanda kwengcindezi yokulawula i-PFAS kusheshisa ukushintshela kwezinye izindlela ezingenayo i-fluorine.

Kungani kwenzeka ukuqhekeka kokuncibilika ekukhishweni kwefilimu ye-PE?

Ukuqhekeka kokuncibilika kwenzeka lapho ukugeleza kokuncibilika kwe-polymer kuguquka kusuka ekushefa okuzinzile kuya ekungazinzini kokunamathela-ukushelela ngemva kokudlula ukucindezeleka okukhulu kokushefa ekuphumeni kwedayi.

Lokhu kuphazamisa ukuqhubeka kwengqimba yokuncibilika ebusweni be-die, okuholela ekuphazamisekeni kwesikhumba sikashaka kanye nokwakheka kwefilimu okungalingani.

Ingozi iyanda ngesivinini esiphezulu somugqa, izikhala ezincane zokudaya, ama-resin anesisindo esikhulu sama-molecule, kanye nama-polyethylene asekelwe ku-metallocene.

Kungani ama-PPA e-fluoropolymer eshintshwa?

Ama-PPA e-Fluoropolymer asebenza ngokuthuthela endaweni yokufa futhi akhe ungqimba lokugcoba olunamandla amancane olunciphisa ukungqubuzana futhi luqinise ukugeleza kokuncibilika.

Kodwa-ke, ukuphikelela kwabo emvelweni njengezinto ezihlobene ne-PFAS kuqhuba imikhawulo yokulawula e-EU, eNyakatho Melika nakwezinye izifunda.

Ngenxa yalokho, abakhiqizi bamafilimu bashintshela ezinhlelweni zokucubungula ezingasebenzisi u-fluorinated ezigcina:

• Ukuqina kwesivinini esiphezulu

• Umswakama ophansi kanye nokucwebezela okuphezulu

• Ukuhlanzeka kwesikhathi eside kwedayi

• Ukuthobela imithetho

Ama-PPA angenayo i-PFAS aqeda kanjani ukuqhekeka kokuncibilika?

Ama-PPA angenayo i-PFAS anciphisa ukuqhekeka kokuncibilika ngokushintsha ukuguquguquka kokuxhumana phakathi kokuncibilika kwe-polymer kanye nobuso bokufa kunokuthembela ekunciphiseni amandla obuso obune-fluorine.

Bakha ungqimba lokuthambisa olulawulwayo lwama-molecule ngokusebenzisana kokubili ne-interface yensimbi kanye ne-polymer matrix, okuqinisa izimo zokushelela ngesikhathi sokukhipha.

Le ndlela icindezela ukungazinzi kokushelela kwenduku, inciphisa ukuguquguquka kokucindezeleka kokucheba, futhi ithuthukisa ukufana kwendawo lapho ikhipha khona amandla amaningi.

Ubuchwepheshe be-PPA obungenayo i-SILIMER PFAS be-PE Film Extrusion

Indlela ama-PPA angenawo ama-SILIMER PFAS asebenza ngayo ku-PE extrusion

Ama-PPA angenazo i-PFAS ochungechungeni lwe-SILIKE SILIMER aklanyelwe izinhlelo zokukhipha i-polyolefin ezidinga ukuzinza okusheshayo nokukhiqizwa kwamafilimu angenazo iziphambeko.

Ukusebenza kwabo kusekelwe ekwakhiweni kwama-molecule anezigaba eziningi:

• Izingxenye ze-polar

Xhumana nezindawo zensimbi (isikulufu, umgqomo, idayisi) bese wakha ungqimba oluqinile lokuthambisa oluhlanganisa ubuso olunciphisa ukunamathelana kokuncibilika futhi luvimbele ukwakheka kwedayi.

• Umgogodla we-polysiloxane

Inikeza ukungqubuzana okuphansi kakhulu kanye nokuqina okuphezulu kokushisa, ithuthukisa ukuziphatha kokugeleza kokuncibilika ngaphansi kokucindezeleka kokucubungula.

•Amaketanga e-hydrocarbon angewona ama-polar

Qinisekisa ukuhambisana nama-matrices e-PE/PP futhi uvumele ukuhlakazeka okufanayo kanye nokufuduka okulawulwayo ngesikhathi sokukhipha.

Lesi sakhiwo senza kube nokwakheka kwesendlalelo sokugcoba esiguquguqukayo, esizivuselelayo esithatha indawo yezindlela zokuguqula ubuso ezisekelwe ku-fluoropolymer.

Yiziphi izinzuzo zokusebenza ezinikezwa yi-PPAs ezingenayo i-SILIMER PFAS?
