Kungani Abakhiqizi Be-Synthetic Turf Besuka Ku-PFAS？
Izinto ze-Per- kanye ne-polyfluoroalkyl (PFAS) zingamakhemikhali okwenziwa avame ukusetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi utshani bokwenziwa, ngenxa yezakhiwo zabo ezingangenisi manzi, ezingangeni amabala, futhi ezihlala isikhathi eside. Kodwa-ke, ukusetshenziswa kwe-PFAS kutshani bokwenziwa kuphakamise ukukhathazeka okukhulu, okuholele ekushintsheni kwezinye izindlela ezingenayo i-PFAS. Ngezansi kunezizathu ezibalulekile ezenza abakhiqizi bagweme i-PFAS kanye nokufuna okuqhubekayo kwezithasiselo zokusebenza kwenqubo ezingenayo i-PFAS (PPAs) kanye nezinye izindlela ezingenayo i-fluorine:
1. Izingozi Zempilo
Inkinga:I-PFAS, evame ukubizwa ngokuthi “amakhemikhali angunaphakade” ngenxa yezibopho zayo eziqhubekayo ze-carbon-fluorine, ihlotshaniswa nezingozi ezinkulu zempilo, okuhlanganisa umdlavuza, ukuphazamiseka kwesistimu yomzimba, kanye nezinkinga zokuthuthukiswa. Etshanini lokwenziwa, i-PFAS engemuva kwekhaphethi, ama-blades, noma i-infill ingadliwa noma ihogelwe, ikakhulukazi yizingane noma abasubathi ezindaweni ezonakele lapho kukhishwa khona uthuli nezinhlayiya.
Ubufakazi:Izifundo, ezifana nombiko weSayensi Yezemvelo kanye Nobuchwepheshe ka-2022, zithole amazinga e-PFAS atholakalayo kumasampula amathe abasubathi abasebenzisa izinkundla zokwenziwa.
Impendulo Yemboni:Abakhiqizi abakhulu manje sebebeka phambili utshani obungenazo i-PFAS, ikakhulukazi ezikoleni nasezindaweni zokudlala, ukuze kuncishiswe umthwalo wemfanelo futhi kuhambisane nezimiso zomsebenzi wokunakekela.
2. Umthelela Wezemvelo: Ukuvimbela Ukungcola Kwesikhathi Eside
Inkinga: I-PFAS ayonakali ngokwemvelo futhi iqoqeke ezindaweni zemvelo. Ukugeleza kwamanzi endle kuye kwabonakala kungcolisa imithombo yamanzi.
Ucwaningo lwesigameko:Ucwaningo lwe-Water Research Foundation lwango-2021 luthole i-PFAS kumasampula angama-78% amanzi angaphansi komhlaba eduze kokufakwa kotshani bokwenziwa.
Isenzo Sokulawula:UMthetho Wokuphoqelelwa Kwamanzi Okuphuza Okuphephile kanye Nokusetshenziswa Kwezidakamizwa eCalifornia (Isiphakamiso 65) ubala i-PFAS njengento elawulwayo.
Uhlaka lwe-EU lokubhalisa, ukuhlola, ukugunyaza kanye nokukhawulela amakhemikhali (REACH) luqeda i-PFAS ezimpahleni zabathengi.
Isixazululo:Izinhlelo zotshani ezingenayo i-PFAS zisusa izembozo ezifakwe i-fluorine bese zihambisana nezindawo ezihlala isikhathi eside (isb. i-cork, i-coconut husk) ukuze kuncishiswe ukuqhubeka kwemvelo.
3. Ingcindezi Yokulawula: Ukuthobela Umthetho Kuqhuba Ushintsho
Imithethonqubo Yomhlaba Wonke:
I-US: Izifundazwe ezifana neCalifornia (uMthethosivivinywa Womhlangano No. 1423, oqala ukusebenza ngo-2024) kanye neNew York ziyalela amazinga e-PFAS angabonakali kumaphrojekthi omphakathi.
I-EU: Ukuvinjelwa kwe-PFAS okuhlongozwayo ngaphansi kwe-REACH kungase kuqale ukusebenza ngo-2025.
Izindinganiso Zokuhlola:Abakhiqizi basebenzisa i-EPA Method 533 (kumasampula aqinile) noma i-ASTM D7968 ukuqinisekisa isimo sokungabi na-PFAS.
Ukuzivumelanisa Nezimo Kwemboni:Izinkampani ezifana ne-TenCate Grass kanye ne-SYNLawn ziguqula imikhiqizo ye-Synthetic Turf ukuze ihlangabezane nalezi zindinganiso, ngokuqinisekiswa okuvela eceleni.
Kungani i-PFAS itholakala otshanini bokwenziwa?
Kusukela maphakathi nekhulu lama-20, izimboni ziye zamukela kakhulu izithasiselo ze-fluorinated process performance (PPAs) njengezinga elijwayelekile ekukhiqizweni kwepulasitiki kanye nezindwangu. Lezi zithasiselo, ezifaka phakathi ama-fluoropolymers njenge-polytetrafluoroethylene derivatives kanye ne-fluoroelastomers, zinezibopho ze-carbon-fluorine (CF) ezihlotshaniswa nezinto ze-per- kanye ne-polyfluoroalkyl (PFAS).
Ngokomlando, ama-PPA afakwe i-fluorine, ikakhulukazi avela ezinkampanini zomkhiqizo ezifana ne-3M, adlale indima ebalulekile ekukhuliseni ukukhiqizwa kotshani bokwenziwa. Avame ukusetshenziswa ezinqubweni ezifana nokukhishwa kwama-blade kanye nokufakwa kwe-backpaint. Lezi zithasiselo azigcini nje ngokuthuthukisa ukusebenza kahle kwe-polyethylene kanye ne-polypropylene extrusion kodwa futhi zithuthukisa ukuqeda kobuso, ukuqina, kanye nokumelana namanzi kotshani. Ngokunciphisa ukwakheka kwe-die kanye nokuvimbela ukuqhekeka kokuncibilika, zenza kube lula ukwakhiwa kwemicu efanayo, kwandise isikhathi eside somkhiqizo, futhi kunciphisa izindleko zokukhiqiza. Lokhu kuthuthuka kube negalelo elikhulu ekuhlangabezaneni nesidingo esikhulayo sezixazululo zotshani ezisebenza kahle kakhulu, ezingadingi ukulungiswa okuningi.
Izixazululo ze-SILIKE ezingenayo i-fluorine
Ukuze kuxazululwe izinselele ezihambisana ne-PFAS, i-SILIKE yethule uchungechunge lwe-SILIMER. Lo mkhiqizo omusha uhlanganisa uhla lwezithasiselo zokucubungula i-polymer (ama-PPA) ahlanzekile angu-100% angena-PFAS futhi angena-fluorine, kanye nama-masterbatches e-PPA angena-PFAS futhi angena-fluorine. Athuthukiswe kusuka ku-polysiloxane eguquliwe ngokwemvelo, lezi zindlela azigcini nje ngokuthuthukisa ukuthambisa kanye nezakhiwo zomphezulu kodwa futhi zikhuthaza indlela ephephile neqhubekayo ngokuqeda ukusetshenziswa kwamakhemikhali e-fluorine ayingozi. Ngokukhetha uchungechunge lwe-SLIKE SILIMER ama-PPA angena-PFAS, ungafaka isandla endaweni enempilo ngenkathi uzuza ekusebenzeni okuphezulu.
Izinzuzo zama-PPA angenawo uchungechunge lwe-SILIMER i-PFAS:
- Ibhekana ngempumelelo nokuqhekeka okuncibilikile (isikhumba soshaka)
- Kunciphisa ukwakheka kwama-die, okuholela ekunciphiseni isikhathi sokuphumula
- Kuthuthukisa ukusebenza kahle, okufaka isandla ekusebenzeni kahle okukhulu
- Kuthuthukisa izakhiwo zokucubungula jikelele
- Kunciphisa kakhulu ukukhubazeka kobuso, okuholela ekuqedeni kobuso okungcono kakhulu ngesikhathi sokukhishwa kwe-polyethylene noma ama-polypropylene turf blades.
Ukuthuthukisa Ukusebenza Kahle Kokucubungula i-Polymer:Izixazululo ze-PPA Zokukhiqiza
Ama-PPA angenawo uchungechunge lwe-SILIKE lwe-SILIMER i-PFAS-Free ayigugu kakhulu kuzo zonke izimboni ezahlukene. Afaneleka kakhulu ekusetshenzisweni kotshani bokwenziwa (utshani bokwenziwa), i-masterbatch esebenzayo, ifilimu yepulasitiki, ukubumba okuvuthayo, i-extrusion, imicu, amashubhu, amashidi, kanye nezintambo. Lezi zixazululo ze-Polymer Processing Aids eziguquguqukayo zenzelwe ukuhlangabezana nezidingo zokukhiqiza ezahlukahlukene ngenkathi kugcinwa amazinga aphezulu okusebenza.
Ukubhekana nokucindezela okukhula kwemithetho kanye nemakethe ukuzesusa i-PFAS kanye nesengezo esisekelwe ku-fluorinekusuka ezinqubweni zabo ze-polymer? Kumabhizinisi azibophezele ekukhiqizeni okuhambisana nemvelo, i-SILIKE inikeza ikhambi elisebenza kahle kakhulu, elingenayo i-PFAS—elilungiselelwe kahle izidingo zakho.
Ukuze uthole eminye imibuzo yokukhiqiza esimeme, sicela uxhumane no-Amy Wang ku-amy.wang@silike.cnnoma vakashelawww.siliketech.com
