Mayankho ena a PPA pansi pa zoletsa za PFAS

PPA (Polymer Processing Additive) yomwe ndi fluoropolymer processing aids, ndi kapangidwe ka fluoropolymer polymer-based polymer ka polymer processing aids, kuti akonze bwino ntchito ya polymer processing, athetse kusungunuka kwa kusungunuka, athetse kusungunuka kwa die, akuwongolera sharkskin, ndi zina zotero. Inayamba kupangidwa ndi DuPont mu 1961 ndipo inayikidwa pamsika m'ma 80s, kenako inayambitsidwa ndi kampani ya 3M kuti iwonjezere kutumiza kunja kwa fluorine elastomer PPA…… Ndi kupita patsogolo kosalekeza kwa ukadaulo, PPA fluorine-containing processing aids imagwiritsidwa ntchito kwambiri ndipo pang'onopang'ono imakhala ndi udindo wofunikira kwambiri pakukonza mafilimu, machubu, ma hoses, zingwe, ndi zina.

Pempho loletsa la PFAS (Perfluoro ndi Polyfluoroalkyl Substances), lokonzedwa ndi akuluakulu a Denmark, Germany, Finland, Norway, ndi Sweden, linaperekedwa ku ECHA pa Januwale 13, 2023, ndi cholinga chochepetsa kutulutsa kwa PFAS m'chilengedwe ndikupanga zinthu ndi njira zotetezeka poletsa Perfluoroalkyl Substances (PFAS) ndi Polyfluoroalkyl Substances (PFAS) zomwe zili ndi atomu imodzi ya kaboni yomwe imapangidwa ndi perfluorine (yomwe ikuyerekezeredwa kukhala mamolekyu 10,000 onse), kuphatikiza ma fluoropolymers otchuka. (PFAS), kuphatikiza ma fluoropolymers otchuka. Mayiko omwe ali mamembala adzavota pa chiletsocho mu 2025. Ngati lingaliro la ku Europe silinasinthe, pamapeto pake lidzathetsa kugwiritsa ntchito ma fluoropolymers wamba monga PTFE ndi PVDF, ndikuletsa kugwiritsa ntchito zinthu zambiri kupatulapo zingapo monga zida zamankhwala, zida zolumikizirana ndi chakudya, maselo amafuta, ndi zina zotero, ndikukhudza kwambiri chilengedwe cha unyolo wonse wamafakitale.

Poyankha, SILIKE yayambitsa pulogalamu yanjira ina yopanda fluorineku PPA yochokera ku Fluorine ——aZothandizira polima zopanda PFAS (PPAS)IziPPA MB yopanda fluorine, Chowonjezera chopanda PTFE ndi polysiloxane masterbatch yosinthidwa mwachilengedwe yomwe imagwiritsa ntchito mphamvu yabwino kwambiri yoyambira ya mafuta a polysiloxanes ndi polarity ya magulu osinthidwa kuti asamukire ndikugwira ntchito pa zida zokonzera panthawi yokonza, zomwe zimapangitsa kuti zikhale zofanana ndi zowonjezera za silicone zopanda Fluorine zomwe zili ndi silicone potulutsa mawaya ndi zingwe, machubu, ndi filimu, ndipo kuchuluka kochepa kwa chowonjezera ichi kumathandizira bwino kusinthasintha kwa utomoni ndi kukonzedwa, komanso mafuta ndi mawonekedwe a pamwamba pa mapulasitiki omwe akutulutsidwa. Kuwonjezera pang'ono kungathandize bwino kuyenda kwa utomoni, kukonzedwa, kukhuthala, ndi mawonekedwe a pamwamba panthawi yotulutsa pulasitiki, kupindulitsa makasitomala a polima ndi dziko lapansi pamene akuwonjezera kupanga ndi khalidwe la zinthu.

PPA MB yopanda Fluorine ya SILIKE, PPA yopanda PFASndiYopanda PTFEZowonjezera zimatha kulowa m'malo mwa fluorine PPA masterbatch, PFAS Polymer Process Additive, PPA MB, PPA products, fluoropolymer, PPAs zochokera ku Fluorine, m'mafakitale ambiri monga mafilimu apulasitiki, zingwe & mawaya, mapaipi ... ndi zina zotero.

Masewero wamba:

Kupititsa patsogolo kusinthasintha kwa pulasitiki ndi magwiridwe antchito a extrusion;

Kuchepetsa mphamvu yamagetsi ndi kuwonongeka kwa zida;

Chepetsani madontho a madzi m'thupi ndikuwongolera khungu la shaki.

Lumikizanani ndi SILIKE kuti mupezePTFE Njira Zina Zowonjezera!
