Chifukwa Chiyani Opanga Ma Turf Opangidwa Akuchoka Ku PFAS?

Per- ndi polyfluoroalkyl substances (PFAS) ndi mankhwala opangidwa omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza ma turf opangira, chifukwa cha zinthu zawo zothamangitsa madzi, zosakanizika, komanso zolimba. Komabe, kugwiritsa ntchito PFAS pakupanga turf kwadzetsa nkhawa zazikulu, zomwe zapangitsa kuti asinthe njira zina zopanda PFAS. Pansipa pali zifukwa zazikulu zomwe opanga akupewa PFAS komanso kufunafuna kosalekeza kwa PFAS-free process performance additives (PPAs) ndi njira zina zopanda fluorine:

1. Kuopsa kwa Thanzi

Nkhani:PFAS, yomwe nthawi zambiri imatchedwa "mankhwala osatha" chifukwa cha kulimbikira kwawo kwa carbon-fluorine, amalumikizidwa ndi zoopsa zathanzi, kuphatikiza khansa, kusokonezeka kwa chitetezo chamthupi, komanso chitukuko. Mu turf yopangira, PFAS yochirikiza kapeti, masamba, kapena kulowetsedwa kumatha kulowetsedwa kapena kulowetsedwa, makamaka ndi ana kapena othamanga pamabwalo owonongeka pomwe fumbi ndi tinthu tating'onoting'ono timatulutsidwa.

Umboni:Kafukufuku, monga lipoti la 2022 Environmental Science & Technology, adapeza milingo ya PFAS m'malovu a othamanga omwe amagwiritsa ntchito mabwalo opangira.

Mayankho a Viwanda:Opanga akuluakulu tsopano amaika patsogolo turf wopanda PFAS, makamaka m'masukulu ndi malo osewerera, kuti achepetse udindo ndikugwirizana ndi mfundo zantchito.

2. Kukhudzidwa Kwachilengedwe: Kupewa Kuipitsidwa Kwanthawi Yaitali
Nkhani: PFAS sichimanyozeka mwachilengedwe ndikudziunjikira muzachilengedwe. Kusefukira kwa turf kumunda kwawonetsedwa kuti kumawononga madzi.

Nkhani Yophunzira:Kafukufuku wa 2021 Water Research Foundation adapeza PFAS mu 78% ya madzi apansi panthaka pafupi ndi kuyika kwa turf.

Zowongolera:California's Safe Drinking Water and Toxic Enforcement Act (Proposition 65) ya California imatchula PFAS ngati chinthu cholamulidwa.

Ndondomeko ya EU ya Kulembetsa, Kuyesa, Kuvomerezeka ndi Kuletsa Mankhwala (REACH) ikuchotsa PFAS muzinthu zogula.

Yankho:Makina a turf opanda PFAS amachotsa zokutira zokhala ndi fluorinated ndi kuwirikiza ndi zodzaza zokhazikika (mwachitsanzo, nkhokwe, mankhusu a kokonati) kuti muchepetse kulimbikira kwa chilengedwe.

3. Kupanikizika Kwadongosolo: Kusintha kwa Kutsatira Kuyendetsa

Malamulo Padziko Lonse:

US: Mayiko ngati California (Assembly Bill No. 1423, 2024 yogwira ntchito) ndi New York amalamula kuti asawonekere ma PFAS pamapulojekiti aboma.

EU: Zoletsedwa za PFAS pansi pa REACH zitha kugwira ntchito pofika 2025.

Miyezo Yoyesera:Opanga amagwiritsa ntchito EPA Method 533 (ya zitsanzo zolimba) kapena ASTM D7968 kuti atsimikizire kuti alibe PFAS.

Kusintha kwa Makampani:Makampani monga TenCate Grass ndi SYNLawn amasinthanso zinthu za Synthetic Turf kuti zigwirizane ndi izi, ndikutsimikiziranso za chipani chachitatu.

Chifukwa chiyani PFAS imapezeka muudzu wopangira?

Kuyambira pakati pa zaka za m'ma 1900, mafakitale akhala akutengera zowonjezera zowonjezera (PPAs) monga mapulasitiki ndi nsalu. Zowonjezera izi, zomwe zimaphatikizapo ma fluoropolymers ngati zotumphukira za polytetrafluoroethylene ndi fluoroelastomers, zimakhala ndi ma bond a carbon-fluorine (CF) omwe amalumikizidwa ndi per- ndi polyfluoroalkyl substances (PFAS).

M'mbuyomu, ma PPA opangidwa ndi fluorinated, makamaka ochokera kumakampani amtundu wa 3M, adathandizira kwambiri kupanga udzu wopangira. Amagwiritsidwa ntchito kwambiri m'njira monga blade extrusion ndi zokutira kumbuyo. Zowonjezera izi sizimangowonjezera mphamvu ya polyethylene ndi polypropylene extrusion komanso zimawonjezera kutha kwa pamwamba, kulimba, komanso kukana madzi kwa turf. Pochepetsa kuchuluka kwa kufa komanso kupewa kusweka kwa kusungunuka, kumathandizira kupanga ulusi wofanana, kukulitsa moyo wazinthu, ndikuchepetsa ndalama zopangira. Kupita patsogolo kumeneku kwathandiza kwambiri kukwaniritsa kufunikira kokulirapo kwa mayankho a turf ochita bwino kwambiri, osakonza bwino.

Matekinoloje a PFAS-Free Synthetic Turf: Njira ina ya fluorine Polymer Processing Aids (PPAs)

Mayankho a SILIKE opanda fluorine

Kuti athane ndi zovuta zokhudzana ndi PFAS, SILIKE idayambitsa mndandanda wa SILIMER. Mzere wazinthu zatsopanozi umaphatikizapo mitundu ingapo ya 100% yoyera ya PFAS-free komanso fluorine-free polymer processing additives (PPAs), pamodzi ndi PFAS-free and fluorine-free PPA masterbatches. Zopangidwa kuchokera ku organically modified polysiloxane, njira zina izi sizimangowonjezera mafuta komanso mawonekedwe apamwamba komanso zimalimbikitsa njira yotetezeka, yokhazikika pochotsa kugwiritsa ntchito mankhwala owopsa a fluorine. Posankha SLIKE SILIMER seriesPFAS-Free PPAs, mutha kuthandizira kuti mukhale ndi thanzi labwino pamene mukupindula ndi ntchito zapamwamba.

Ubwino wa SILIMER mndandanda wa PFAS-Free PPAs:

- Amathana bwino ndi fracture yosungunuka (chikopa cha shark)
- Amachepetsa kuchuluka kwa kufa, zomwe zimapangitsa kuchepa kwa nthawi
- Imawonjezera kutulutsa, kumathandizira kuti magwiridwe antchito azitha kugwira ntchito bwino
- Kupititsa patsogolo katundu wonse wa processing
- Imachepetsa kwambiri zolakwika zapamtunda, zomwe zimapangitsa kuti pakhale kutsirizika kwapamwamba pakutulutsa masamba a polyethylene kapena polypropylene turf.

Kupititsa patsogolo Kuchita Bwino kwa Polima:PPA Solutions for Manufacturing
SILIKE's SILIMER mndandanda wa PFAS-Free PPAs ndiwofunika kwambiri m'mafakitale osiyanasiyana. Ndioyenera makamaka kuyika pakupanga utoto (udzu wopangira), masterbatch yogwira ntchito, filimu yapulasitiki, kuumba nkhonya, extrusion, ulusi, machubu, mapepala, ndi zingwe. Mayankho osinthika awa a Polymer Processing Aids adapangidwa kuti akwaniritse zosowa zosiyanasiyana zopanga ndikusunga magwiridwe antchito apamwamba.

Poyang'anizana ndi kukula kwamalamulo ndi kukakamizidwa kwa msika kutiChotsani PFAS ndi zowonjezera za fluorines kuchokera ku ma polima awo? Kwa mabizinesi odzipereka kupanga zokometsera zachilengedwe, SILIKE imapereka yankho lapamwamba, laulere la PFAS - logwirizana ndi zosowa zanu.
