Kungani kwenzeka ukuqhekeka kokuncibilika ekukhishweni kwefilimu ye-PE?

Ukuqhekeka kokuncibilika kungenye yeziphambeko ezivame kakhulu ebusweni ekukhishweni kwefilimu ye-polyethylene (PE), ikakhulukazi ekucutshungulweni okusheshayo kwe-LLDPE, HDPE, kanye ne-mLLDPE.

Ngokuvamile kubonakala kanje:

• Ukuthungwa kobuso besikhumba sikaSharks

• Ukubukeka kwefilimu okungekuhle noma okungajwayelekile

• Ukungazinzi kokugeleza komoya lapho kuphuma khona idayi

• Ukulahlekelwa ukucaca kokukhanya

Imbangela

Ukuqhekeka kokuncibilika kubangelwa ukungazinzile kokugeleza kobuso lapho ukuncibilika kwe-polymer kudlula kudayi ngaphansi kokucindezeleka okukhulu kokucheba.

Uma ukucindezeleka kokusika kudlula umkhawulo obalulekile:

• Ukuncibilika kwe-polymer akukwazi ukugcina ukugeleza okubushelelezi

• Ukuziphatha kokushelela kwenduku kwenzeka odongeni lwedayi

• Ungqimba olungaphezulu luyaphuka ngezikhathi ezithile

Lokhu kuba kubi kakhulu ngaphansi kwalokhu okulandelayo:

• Ukukhipha isivinini esikhulu

• Izikhala ezincane zedayi

• Ama-resin anesisindo sama-molecule amaningi

• Amabanga e-PE asekelwe ku-Metallocene

Kungani kusetshenziswa ama-PPA e-fluoropolymer endabuko

Sekungamashumi eminyaka, i-Polymer Processing Aids (PPAs) esekelwe ku-fluoropolymer isetshenziswa ukuxazulula izinkinga zokuqhekeka kokuncibilika ekukhishweni kwefilimu ye-PE.

Basebenza ngokuthi:

• Ukuthuthela endaweni yokufa

• Ukwakha ungqimba olune-fluorine olunamandla aphansi ebusweni

• Ukunciphisa ukungqubuzana kwe-melt-die

• Ukuvumela ukushelela odongeni

Lokhu kusiza ekuqiniseni ukugeleza kokuncibilika nokuqeda ukukhubazeka kwesikhumba sikashaka.

Kodwa-ke, ukwanda kwengcindezi yokulawula ezintweni ezihlobene ne-PFAS kushintsha indlela abaprosesa ababhekana ngayo nalesi sixazululo.

Kungani abakhiqizi befuna izixazululo ezingezona i-fluoropolymer

Ukushintsha kusuka kuma-PPA e-fluoropolymer kuqhutshwa yi:

Ingcindezi yokulawula

• Iziphakamiso zemikhawulo ze-EU REACH PFAS

• Izidingo zokubika ze-US EPA TSCA PFAS

• Izinhlelo zokuqapha ze-PFAS zomhlaba wonke

Izidingo ze-OEM kanye nomkhiqizo

• Izidingo zokupakisha ezingenayo i-PFAS

• Ukuhlolwa kokuhambisana nokusimama

• Imigomo yomnotho oyindilinga

Izinkinga zobuchwepheshe kanye nokusebenza

• Ukungcola kwe-fluoropolymer okusele emifudlaneni yokuvuselela kabusha

• Izingozi zokufaneleka ukuthumela kwamanye amazwe

• Ukungaqiniseki kochungechunge lokuphakelwa

Ngenxa yalokho, abaprosesa bafuna ngenkuthalo:

Indlela yokuqeda ukuqhekeka kokuncibilika ngaphandle kwama-fluoropolymers

Ingabe ukuqhekeka okuncibilikisiwe kungasuswa ngaphandle kwama-fluoropolymers?

Yebo.

Iningi labakhiqizi bezithako ze-polymer baqalise izinsiza zokucubungula ezingenayo i-PFAS, benikeza indlela ehlukile engancikile ekumbozweni kobuso okune-fluorine.

Esikhundleni sokudala ifilimu ye-fluoropolymer ehlala njalo, lezi zinhlelo zisebenza ngokulawula ukuthambisa okuguquguqukayo kwe-interfacial.

Indlela ukucubungula okungenawo ama-PFAS okusiza ngayo ukuqeda ukuqhekeka okuncibilikile

Ama-PPA angenayo i-PFAS (ikakhulukazi izinhlelo ezisekelwe ku-silicone) anciphisa ukuqhekeka kokuncibilika ngendlela ehlukile:

1. Ukuqina kokushelela kwe-interfacial

Zishintsha ukusebenzisana phakathi kobuso be-polymer bokuncibilika kanye nobokufa, zinciphisa ukungazinzi kokunamathela nokushelela.

2. Ukwehla kokuguquguquka kokucindezeleka kokugunda

Ngokulungisa ukuziphatha kokugeleza ezingeni lama-molecule, banciphisa izinguquko eziphuthumayo zokucindezeleka ekuphumeni kwe-die.

3. Ukwakheka kwesendlalelo sokuthambisa esinamandla

Isendlalelo sama-molecule esizilungisayo sakha endaweni exhumanayo, sihlala sizinza izimo zokukhipha.

4. Ukufana kokugeleza kokuncibilika okuthuthukisiwe

Ukuncibilika kwe-polymer kugcina iphrofayili yejubane elihambisanayo kuyo yonke idayisi.

Ama-PPA angenayo i-SILIMER PFAS okususa ukuqhekeka okuncibilikile

Izinsiza zokucubungula zamahhala ze-SILIKE SILIMER PFASzenzelwe ngqo izinhlelo zokukhipha i-polyolefin ezidinga ukuzinza okusheshayo kanye nekhwalithi ephezulu yobuso ekukhiqizweni kwamafilimu.

Zithuthukiswa njengezindlela ze-PPA ze-fluoropolymer ze:

• Ukukhishwa kwefilimu ye-LLDPE

• Ukucutshungulwa kwefilimu ye-HDPE

• Imigqa yefilimu evuthelwa ngesivinini esikhulu ye-mLLDPE

Indlela ubuchwepheshe be-SILIMER PFAS-Free Processing Aid Alternative esikhundleni se-Fluoropolymer PPAs obusebenza ngayo

Izinzuzo Zokusebenza Zochungechunge lwe-SILIKE SILIMER lwe-PFAS Olungenazo Izixazululo Ezihlukile kanye Nezingenayo I-Fluorine ku-PE Film Extrusion

Uma kusetshenziswa ezinhlelweni zokukhiqiza amafilimu e-PE, uchungechunge lwe-SILIKE SILIMER lwe-Non-PFAS Process Aids lungasiza:

♦ Susa ukuqhekeka okuncibilikile kanye nokukhubazeka kwesikhumba sikashaka
