Chifukwa Chake KufunikaNjira Zina za PTFE (PFAS)?

M'dziko lamakono lomwe likusintha mofulumira la zipangizo zokhazikika, mafakitale akukumana ndi mavuto owonjezereka kuti agwiritse ntchito njira zotetezera chilengedwe. Mapulasitiki a uinjiniya, omwe amadziwika kuti ndi olimba komanso osinthasintha, nawonso ndi osiyana. Kwa zaka zambiri, PTFE (Polytetrafluoroethylene) yakhala ikugwiritsidwa ntchito kwambiri pa mapulasitiki a uinjiniya, yomwe imayamikiridwa chifukwa cha kukana kwawo mankhwala, kusagwirizana kochepa, komanso kukhazikika kwa kutentha.

Komabe, PTFE ndi ya banja la PFAS (Per- ndi Polyfluoroalkyl Substances), lomwe ladzutsa nkhawa zazikulu zokhudzana ndi chilengedwe chifukwa cha kupirira kwake komanso kukana kuwonongeka. Nthawi zambiri amatchedwa "mankhwala osatha," PFAS ali ndi kuthekera kodziunjikira m'chilengedwe ndikuyika pachiwopsezo thanzi la anthu, kuphatikiza mavuto okhudzana ndi chitetezo chamthupi ndi endocrine, magwiridwe antchito a chiwindi, komanso matenda oopsa kwambiri monga khansa.

Poyankha mavutowa, mayiko ambiri akukhwimitsa malamulo okhudza mankhwala a PFAS. Mwachitsanzo:

Lamulo la REACH la European Union lazindikira kuti PFAS ndi "chinthu chomwe chimadetsa nkhawa kwambiri," zomwe zapangitsa kuti pakhale malamulo okhwima pakugwiritsa ntchito kwake.

Bungwe la US Environmental Protection Agency (EPA) layamba kuyang'anira ndi kuthetsa mapulani a mankhwala a PFAS.

Ndiye, kodi mapulasitiki opanga zinthu zamakono angasunge bwanji magwiridwe antchito awo apamwamba pomwe akuchepetsa kuwononga chilengedwe? Mayankho a PFAS-Free ndi PTFE-Free amapereka yankho labwino kwambiri, kupereka zabwino zomwezo popanda zoopsa zachilengedwe ndi thanzi.

Kodi njira ina m'malo mwa PTFE ndi iti? Kuchita bwino kwambiri,Zowonjezera Zopanda PFAS za Pulasitiki Zauinjiniya

Kuyambitsa Zowonjezera Zosavala za SILIKE Fluorine ndi Njira Zina za PTFE

Ubwino Waukulu wa PTFE Replacement Additive SILIKE LYSI-701 pa Mapulasitiki a Uinjiniya:

1. Kapangidwe Kopanda Fluorine: Kapangidwe kopanda PFAS konse komwe kamagwirizana ndi miyezo yokhwima yapadziko lonse yokhudza chilengedwe.

2. Kulimba Kowonjezereka kwa Kusavala: Ngakhale pang'ono chabe pa izi zitha kusintha kwambiri kulimba ndi moyo wa pulasitiki waukadaulo poyerekeza ndi PTFE.

3. Mafuta Opaka Mwapamwamba: Amachepetsa kukangana bwino komanso amathandizira kukonza bwino, zomwe zimapangitsa kuti ntchito ikhale yabwino.

4. Kugwiritsa Ntchito Kwambiri: Koyenera zipangizo zosiyanasiyana monga PA6, PA66, PC, ABS, POM, PBT, PPS, ndi mapulasitiki ena ambiri auinjiniya.

Mayeso a labotale amatsimikizira kuti 3 wt% LYSI-701 mu POM imasonyeza kukana kwapamwamba kwa kukalamba komanso coefficient yotsika ya kukangana (COF) poyerekeza ndi 10 wt% PTFE pansi pa mikhalidwe yofanana yoyesera.

Buku Latsopano Lopewera PTFE ndi PFAS (Forever Chemicals) mu Uinjiniya wa Zopangira Mapulasitiki

Kwa ofufuza omwe amagwira ntchito yokhudza pulasitiki ya uinjiniya, kodi mukukumana ndi mavuto omwe amabwera chifukwa chowonjezera kuwunika malamulo pa PFAS mu pulasitiki ya uinjiniya? Kodi mukufuna zowonjezera zogwira ntchito bwino, zotsutsana ndi kuphulika, kapena zosintha za pulasitiki ya uinjiniya, kapena cholowa m'malo mwa PTFE chomwe chimaika patsogolo thanzi la chilengedwe?

Kubwera kwa zinthu zatsopano zopanda PFAS kwatsegula mwayi wambiri. Njira zina izi sizingogwirizana ndi momwe PTFE imagwirira ntchito komanso kuchepetsa kuwonongeka kwa chilengedwe.

Pokhala ndi maganizo osamala za chitetezo komanso oteteza chilengedwe, timatsogolera makasitomala athu ku zovuta zomwe zikuchitika pamsikawu. SILIKE yakhala ikutsogolera njira zingapo zopanda PFAS zomwe zapangidwira ntchito zaukadaulo wa pulasitiki. Tili ngati mnzanu wothandizana nanu pakufunafuna njira zina zokhazikika m'malo mwa PTFE komanso kusiya zinthu zoopsa za PFAS.

SILIKE ikukupemphani kuti mulumikizane nafe kuti mufufuze zatsopanoziZosintha Zogwira Mtima za Tribology ndi Njira Zina za PTFEzosankha ndi momwe zingathandizire mapulojekiti anu.
