Izixazululo ezihlukile ze-PPA ngaphansi kwemingcele ye-PFAS

I-PPA (i-Polymer Processing Additive) okuyi-fluoropolymer processing aids, iyisakhiwo esisekelwe ku-fluoropolymer polymer se-polymer processing aids, ukuthuthukisa ukusebenza kokucubungula i-polymer, ukuqeda ukuqhekeka kokuncibilika, ukuxazulula ukwakheka kwe-die, ukuthuthukisa isikhumba se-sharks, njalo njalo. Yasungulwa okokuqala yiDuPont ngo-1961 yafakwa emakethe ngawo-1980, yabe isiqaliswa yinkampani ye-3M ukwandisa ukuthunyelwa kwe-fluorine elastomer PPA…… Ngentuthuko eqhubekayo yobuchwepheshe, i-PPA fluorine-containing processing aids isetshenziswa kabanzi futhi kancane kancane ithatha isikhundla esibaluleke kakhulu ekucutshungulweni kwamafilimu, amashubhu, amapayipi, izintambo, kanye neminye imikhakha.

Isiphakamiso sokuvimbela i-PFAS (Perfluoro and Polyfluoroalkyl Substances), esilungiselelwe yiziphathimandla zaseDenmark, eJalimane, eFinland, eNorway, naseSweden, sathunyelwa ku-ECHA ngoJanuwari 13, 2023, ngenhloso yokunciphisa ukukhishwa kwe-PFAS emvelweni nokwenza imikhiqizo nezinqubo ziphephe ngokuvimba i-Perfluoroalkyl Substances (PFAS) kanye ne-Polyfluoroalkyl Substances (PFAS) equkethe okungenani i-athomu eyodwa yekhabhoni efakwe i-perfluorine (okulinganiselwa ukuthi iyi-molecules eziyi-10,000 sezizonke), kufaka phakathi ama-fluoropolymers athandwayo. (PFAS), kufaka phakathi ama-fluoropolymers athandwayo. Amazwe angamalungu azovota ngokuvinjelwa ngo-2025. Isiphakamiso saseYurophu, uma singashintshiwe, ekugcineni sizoqeda ukusetshenziswa kwama-fluoropolymers avamile njenge-PTFE kanye ne-PVDF, sinciphise ukusetshenziswa okuningi ngaphandle kwamadivayisi ezokwelapha, izinto zokuxhumana zokudla, amaseli kaphethiloli, njll., futhi sithinte kakhulu imvelo yochungechunge lonke lwezimboni.

Ephendula, i-SILIKE yethule i-enye indlela engenayo i-fluorineku-PPA esekelwe ku-Fluorine ——aIzinsiza zokucubungula i-polymer ezingenayo i-PFAS (i-PPA)LokhuI-PPA MB engena-fluorine, Isithasiselo esingenayo i-PTFE siyi-polysiloxane masterbatch eguquliwe ngokwemvelo esebenzisa umphumela omuhle kakhulu wokuthambisa wokuqala wama-polysiloxanes kanye ne-polarity yamaqembu aguquliwe ekufudukeni nasekusebenzeni emishinini yokucubungula ngesikhathi sokucubungula, okuholela ekusebenzeni okufanayo nesithasiselo esiqukethe i-silicone esingenayo i-Fluorine ekukhishweni kwezintambo nezintambo, amapayipi, nefilimu, futhi inani elincane lalesi sithasiselo lithuthukisa ngempumelelo ukugeleza kwe-resin kanye nokucutshungulwa, kanye nezici zokuthambisa kanye nobuso bepulasitiki ekhishwayo. Ukwengezwa kwenani elincane kungathuthukisa ngempumelelo ukugeleza kwe-resin, ukucutshungulwa, ukuthambisa, kanye nezakhiwo zobuso ngesikhathi sokukhishwa kwepulasitiki, kuzuze amakhasimende e-polymer kanye nomhlaba ngenkathi kukhulisa ukukhiqizwa kanye nekhwalithi yomkhiqizo.

I-PPA MB engena-Fluorine ye-SILIKE, I-PPA engenayo i-PFAS, futhiAyinayo i-PTFEIzithasiselo zingangena esikhundleni se-fluorine PPA masterbatch, i-PFAS Polymer Process Additive, i-PPA MB, imikhiqizo ye-PPA, i-fluoropolymer, ama-PPA asekelwe ku-Fluorine, ezimbonini eziningi ezifana namafilimu epulasitiki, izintambo kanye nezintambo, amapayipi...njll.

Ukusebenza okuvamile:

Thuthukisa ukugeleza kokucubungula ipulasitiki kanye nokusebenza kahle kokukhipha;

Nciphisa i-torque kanye nokuguguleka kwemishini;

Nciphisa ukuvuza kwamanzi futhi uthuthukise ukwenzeka kwesikhumba sikashaka.

Xhumana ne-SILIKE bese uthola eyakhoIzixazululo Ezingeziwe Ze-PTFE!
