Chifukwa chiyani opanga ma turf opanga akuchoka ku PFAS？

Zinthu zopangidwa ndi Per- ndi polyfluoroalkyl (PFAS) ndi mankhwala opangidwa omwe amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo udzu wopangidwa, chifukwa cha mphamvu zawo zoletsa madzi, zosabala, komanso zokhalitsa. Komabe, kugwiritsa ntchito PFAS mu udzu wopangidwa kwabweretsa nkhawa zazikulu, zomwe zapangitsa kuti anthu asinthe njira zina zopanda PFAS. Nazi zifukwa zazikulu zomwe opanga akupewa PFAS ndi kufunafuna kwa PFAS-free process performance additives (PPAs) ndi njira zina zopanda fluorine:

1. Zoopsa pa Thanzi

Nkhani:PFAS, yomwe nthawi zambiri imatchedwa "mankhwala osatha" chifukwa cha ma bond awo a carbon-fluorine omwe amapitilira, imalumikizidwa ndi zoopsa zazikulu paumoyo, kuphatikizapo khansa, kusokonezeka kwa chitetezo chamthupi, komanso mavuto a chitukuko. Mu udzu wopangidwa, PFAS yomwe ili kumbuyo kwa kapeti, masamba, kapena zinthu zodzaza imatha kudyedwa kapena kupumidwa, makamaka ndi ana kapena othamanga m'minda yowonongeka komwe fumbi ndi tinthu tating'onoting'ono timatulutsidwa.

Umboni:Kafukufuku, monga lipoti la 2022 Environmental Science & Technology, adapeza kuchuluka kwa PFAS komwe kumaonekera m'malovu a othamanga omwe amagwiritsa ntchito minda yopangidwa.

Yankho la Makampani:Opanga akuluakulu tsopano akuika patsogolo udzu wopanda PFAS, makamaka masukulu ndi malo osewerera, kuti achepetse udindo ndikugwirizana ndi mfundo za udindo wosamalira.

2. Zotsatira za Chilengedwe: Kupewa Kuipitsidwa Kwa Nthawi Yaitali
NkhaniPFAS siiwonongeka mwachilengedwe ndipo siimadziunjikira m'malo osungiramo zinthu zachilengedwe. Madzi otuluka m'munda wa dothi awonetsedwa kuti amadetsa madzi.

Phunziro la Nkhani:Kafukufuku wa 2021 Water Research Foundation adapeza PFAS mu 78% ya zitsanzo za pansi pa nthaka pafupi ndi malo opangira udzu.

Zochita Zoyang'anira:Lamulo la California la Madzi Omwa Moyenera ndi Kutsata Malamulo a Poizoni (Proposition 65) limalemba kuti PFAS ndi mankhwala olamulidwa.

Ndondomeko ya EU yolembetsa, kuwunika, kuvomereza ndi kuletsa mankhwala (REACH) ikuchotsa PFAS mu katundu wogwiritsidwa ntchito ndi anthu.

Yankho:Makina opanda udzu a PFAS amachotsa zokutira zofewa ndikuphatikiza ndi zodzaza zokhazikika (monga cork, kokonati) kuti achepetse kupitirira kwa chilengedwe.

3. Kupanikizika kwa Malamulo: Kutsatira Malamulo Kumayendetsa Kusintha

Malamulo Padziko Lonse:

US: Mayiko monga California (Assembly Bill No. 1423, kuyambira 2024) ndi New York alamula kuti PFAS isadziwike m'mapulojekiti aboma.

EU: Ziletso za PFAS zomwe zikuperekedwa motsatira REACH zitha kuyamba kugwira ntchito pofika chaka cha 2025.

Miyezo Yoyesera:Opanga amagwiritsa ntchito EPA Method 533 (pa zitsanzo zolimba) kapena ASTM D7968 kuti atsimikizire kuti PFAS siili ndi mankhwala.

Kusintha kwa Makampani:Makampani monga TenCate Grass ndi SYNLawn akusintha zinthu za Synthetic Turf kuti zikwaniritse miyezo iyi, ndi kutsimikiziridwa ndi chipani chachitatu.

Nchifukwa chiyani PFAS imapezeka mu udzu wopangira?

Kuyambira pakati pa zaka za m'ma 1900, mafakitale akhala akugwiritsa ntchito zowonjezera za fluorinated process performance (PPAs) monga muyezo popanga mapulasitiki ndi nsalu. Zowonjezera izi, zomwe zimaphatikizapo ma fluoropolymers monga ma polytetrafluoroethylene derivatives ndi ma fluoroelastomers, zimakhala ndi ma bond a carbon-fluorine (CF) omwe amagwirizanitsidwa ndi zinthu za per- ndi polyfluoroalkyl (PFAS).

M'mbuyomu, ma PPA okhala ndi fluorine, makamaka ochokera kumakampani opanga zinthu monga 3M, akhala ndi gawo lofunika kwambiri pakukweza kupanga udzu wopangidwa. Amagwiritsidwa ntchito kwambiri pazinthu monga kukulitsa masamba ndi zokutira kumbuyo. Zowonjezera izi sizimangowonjezera kugwira ntchito bwino kwa polyethylene ndi polypropylene extrusion komanso zimawonjezera kukongola kwa pamwamba, kulimba, komanso kukana madzi kwa udzu. Mwa kuchepetsa kusungunuka kwa ufa ndikuletsa kusungunuka, zimathandiza kupanga ulusi wofanana, kukulitsa nthawi yayitali ya chinthucho, ndikuchepetsa ndalama zopangira. Kupita patsogolo kumeneku kwakhala kofunikira pakukwaniritsa kufunikira kwakukulu kwa njira zothetsera udzu zomwe sizimasamalidwa bwino komanso zosagwira ntchito bwino.

Ukadaulo wa PFAS-Free Synthetic Turf: Njira ina m'malo mwa fluorine Polymer Processing Aids (PPAs)

Mayankho a SILIKE opanda fluorine

Pofuna kuthana ndi mavuto okhudzana ndi PFAS, SILIKE idayambitsa mndandanda wa SILIMER. Mtundu watsopanowu wazinthu umaphatikizapo zowonjezera za 100% pure PFAS-free and fluorine-free polymer processing (PPAs), pamodzi ndi PPAS-free and fluorine-free PPA masterbatches. Zopangidwa kuchokera ku polysiloxane yosinthidwa mwachilengedwe, njira zina izi sizimangowonjezera mafuta ndi mawonekedwe a pamwamba komanso zimalimbikitsa njira yotetezeka komanso yokhazikika pochotsa kugwiritsa ntchito mankhwala owopsa a fluorine. Mukasankha mndandanda wa SLIKE SILIMER PFAS-Free PPAs, mutha kuthandizira kukhala ndi malo abwino komanso kupindula ndi magwiridwe antchito apamwamba.

Ubwino wa ma SILIMER series PFAS-Free PPAs:

- Imathandiza kuthetsa kusweka kwa ming'alu (sharkskin)
- Amachepetsa kuchuluka kwa ma die buildup, zomwe zimapangitsa kuti nthawi yopuma ichepe
- Zimathandizira kuti ntchito iyende bwino, zomwe zimathandiza kuti ntchito iyende bwino
- Zimawongolera zinthu zonse zogwirira ntchito
- Amachepetsa kwambiri zolakwika pamwamba, zomwe zimapangitsa kuti pamwamba pakhale bwino kwambiri panthawi yotulutsa masamba a polyethylene kapena polypropylene.

Kupititsa patsogolo Kugwiritsa Ntchito Polima Moyenera:Mayankho a PPA Opangira Zinthu
Ma PPA a SILIKE a SILIKE a SILIMER ndi ofunika kwambiri m'mafakitale osiyanasiyana. Amagwiritsidwa ntchito makamaka mu udzu wopangidwa (udzu wopangira), masterbatch yogwira ntchito, filimu ya pulasitiki, kupanga ma blow molding, extrusion, ulusi, machubu, mapepala, ndi zingwe. Mayankho osinthika awa a Polymer Processing Aids adapangidwa kuti akwaniritse zosowa zosiyanasiyana zopangira pomwe akusunga miyezo yapamwamba yogwirira ntchito.

Kukumana ndi kukakamizidwa kwakukulu kwa malamulo ndi msika kutiChotsani PFAS ndi zowonjezera zochokera ku fluorineKodi ndi njira ziti zomwe zimachokera ku njira zawo zopangira polima? Kwa mabizinesi odzipereka kupanga zinthu zosamalira chilengedwe, SILIKE imapereka njira yabwino kwambiri, yopanda PFAS—yokonzedwa bwino kuti igwirizane ndi zosowa zanu.

Kuti mudziwe zambiri zokhudza kupanga zinthu zokhazikika, chonde lemberani Amy Wang paamy.wang@silike.cnkapena pitaniwww.siliketech.com
