Chifukwa ChofunikiraNjira Zina za PTFE (PFAS)?

M'dziko lamakono lomwe likupita patsogolo kwambiri lazinthu zokhazikika, mafakitale akuyang'anizana ndi chitsenderezo chowonjezereka kuti atenge njira zothetsera chilengedwe. Mapulasitiki aumisiri, omwe amadziwika kuti ndi olimba komanso osinthasintha, ndi chimodzimodzi. Kwa zaka zambiri, PTFE (Polytetrafluoroethylene) yakhala ikupita ku zida zamapulasitiki opangira uinjiniya, zamtengo wapatali chifukwa cha kukana kwawo kwamankhwala, kugundana kochepa, komanso kukhazikika kwamafuta ambiri.

Komabe, PTFE ndi ya banja la PFAS (Per- ndi Polyfluoroalkyl Substances), lomwe ladzutsa nkhawa za chilengedwe chifukwa cha kulimbikira kwake komanso kukana kuwonongeka. Nthawi zambiri amatchedwa "mankhwala osatha," PFAS imatha kudziunjikira m'chilengedwe ndikuyika pachiwopsezo ku thanzi la anthu, kuphatikiza zovuta zokhudzana ndi chitetezo chamthupi ndi endocrine, magwiridwe antchito a chiwindi, komanso zovuta zina monga khansa.

Poyankha zovutazi, mayiko ambiri akukhazikitsa malamulo ozungulira zinthu za PFAS. Mwachitsanzo:

Lamulo la European Union la REACH lazindikira kuti PFAS ndi "chinthu chodetsa nkhawa kwambiri," zomwe zimapangitsa kuti aziletsa kugwiritsa ntchito kwake.

Bungwe la US Environmental Protection Agency (EPA) layambitsa ndondomeko zowunikira ndi kuchotseratu mankhwala a PFAS.

Ndiye, kodi mapulasitiki opangira uinjiniya angasunge bwanji magwiridwe antchito awo apamwamba ndikuchepetsa kuwononga chilengedwe? Mayankho a PFAS-Free ndi PTFE-Free amapereka yankho loyenera, lopereka maubwino ochita bwino kwambiri popanda kuwopsa kwa chilengedwe ndi thanzi.

M'malo mwa PTFE ndi chiyani? Kuchita bwino kwambiri,Zowonjezera Zaulere za PFAS za Engineering Plastics

Tikubweretsa SILIKE Fluorine-Free Wear-Resistant Additives ndi PTFE Alternatives

Ubwino Waikulu wa PTFE M'malo Wowonjezera SILIKE LYSI-701 wa Engineering Pulastiki:

1. Mapangidwe Opanda Fluorine: Mapangidwe athunthu opanda PFAS omwe amagwirizana ndi miyezo yolimba yachilengedwe padziko lonse lapansi.

2. Kukaniza Kuvala Kwambiri: Ngakhale pang'ono zowonjezera izi zingathe kupititsa patsogolo kulimba ndi moyo wa mapulasitiki a engineering poyerekeza ndi PTFE.

3. Lubrication Yapamwamba: Imachepetsa mikangano bwino ndikuwonjezera magwiridwe antchito, kuyendetsa bwino ntchito.

4. Wide Applicability: Yoyenera pazinthu zosiyanasiyana monga PA6, PA66, PC, ABS, POM, PBT, PPS, ndi mapulasitiki ambiri a engineering.

Mayeso a labotale amatsimikizira: 3 wt% LYSI-701 mu POM amawonetsa kukana kwamphamvu kovala komanso kutsika kocheperako (COF) poyerekeza ndi 10 wt% PTFE pansi pamiyeso yofanana.

Kalozera Watsopano Wopewa PTFE ndi PFAS (Forever Chemicals) mu Engineering Plastics Products

Kwa ofufuza omwe amagwira ntchito zamapulasitiki a engineering, kodi mukuyang'ana zovuta zomwe zimadza chifukwa chakuchulukirachulukira kwa PFAS mu mapulasitiki a engineering? Kodi mukuyang'ana zowonjezera zogwira ntchito kwambiri, anti-abrasion agents, kapena modifiers of engineering plastics, kapena m'malo mwa PTFE yomwe imayika patsogolo thanzi la chilengedwe?

Kubwera kwazinthu zopanda pake za PFAS kumatsegula mwayi wadziko lapansi. Njira zinazi zili ndi kuthekera osati kungofanana ndi magwiridwe antchito a PTFE komanso kuchepetsa momwe chilengedwe chimakhalira.

Pokhala ndi malingaliro osamala zachitetezo komanso okonda zachilengedwe, timawongolera makasitomala athu kuzovuta za msika womwe ukupita patsogolo. SILIKE adachita upainiya njira zingapo zopanda PFAS zopangira mapulasitiki a uinjiniya. Tiyima ngati mthandizi wanu pakufuna njira zina zokhazikika za PTFE komanso kusiya zinthu zomwe zingakhale zoopsa za PFAS.

SILIKE akukupemphani kuti mulumikizane nafe kuti muwone zatsopanoziZosintha Zothandiza za Tribology ndi Njira Zina za PTFEzosankha ndi momwe angapindulire mapulojekiti anu.
