Kungani Abakhiqizi Be-Synthetic Turf Besuka Ku-PFAS?

I-Per- kanye ne-polyfluoroalkyl substances (PFAS) ngamakhemikhali okwenziwa avame ukusetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi i-synthetic turf, ngenxa yezakhiwo zawo zokuxosha amanzi, ukumelana namabala, nezihlala isikhathi eside. Kodwa-ke, ukusetshenziswa kwe-PFAS ku-synthetic turf kuphakamise ukukhathazeka okukhulu, okwenze ukuthi kuguqukele kwezinye izindlela ezingenayo i-PFAS. Ngezansi izizathu ezibalulekile abakhiqizi bagwema i-PFAS kanye nesifiso esiqhubekayo se-PFAS-free process performance additives (PPAs) nezinye izindlela ezingenayo i-fluorine:

1. Izingozi Zezempilo

Inkinga:I-PFAS, evame ukubizwa ngokuthi "amakhemikhali angunaphakade" ngenxa yokuphikelela kwebhondi ye-carbon-fluorine, ixhunywe ezingozini ezinkulu zezempilo, ezihlanganisa umdlavuza, ukuphazamiseka kwamasosha omzimba, kanye nezinkinga zentuthuko. Ku-synthetic turf, i-PFAS ekusekelweni kukakhaphethi, izindwani, noma ukugcwaliswa kungangenwa noma kuhogelwe, ikakhulukazi izingane noma abasubathi ezinkundleni ezonakele lapho kukhishwa khona uthuli nezinhlayiya.

Ubufakazi:Izifundo, ezinjengombiko we-Environmental Science & Technology wango-2022, zithole amazinga e-PFAS abonakalayo kumasampula amathe abasubathi abasebenzisa izinkundla zokwenziwa.

Impendulo Yezimboni:Abakhiqizi abakhulu manje babeka phambili i-PFAS-free turf, ikakhulukazi izikole nezinkundla zokudlala, ukuze banciphise isikweletu futhi bahambisane nemigomo yomsebenzi wokunakekela.

2. Umthelela Wendawo: Ukuvimbela Ukungcoliswa Kwesikhathi Eside
Inkinga: I-PFAS ayehlisi ngokwemvelo futhi iqongelela kuma-ecosystems. Ukugeleza kwensimu ye-Turf kukhonjiswe ukuthi kungcolisa amanzi.

Ucwaningo lwesigameko:Ucwaningo lwango-2021 lwe-Water Research Foundation luthole i-PFAS ku-78% wamasampula amanzi angaphansi komhlaba eduze nokufakwa kwe-synthetic turf.

Isenzo Sokulawula:Umthetho Wamanzi Okuphuza Aphephile wase-California kanye Nomthetho Wokuphoqelela Ubuthi (Isiphakamiso 65) ubala i-PFAS njengento elawulwayo.

Uhlaka lwe-EU Lokubhaliswa, Ukuhlola, Ukugunyazwa kanye Nokukhawulelwa Kwamakhemikhali (REACH) luqeda i-PFAS ezimpahleni zabathengi.

Isixazululo:Izinhlelo ze-turf zamahhala ze-PFAS zisusa ukumbozwa okukhanyayo futhi zibhangqwe nokugcwaliswa okusimeme (isb, ukhokho, ikhoba likakhukhunathi) ukunciphisa ukuphikelela kwemvelo.

3. Ingcindezi Yokulawula: Ukuhambisana Noshintsho Lokushayela

Imithetho Yomhlaba Wonke:

E-US: Amazwe afana ne-California (Assembly Bill No. 1423, esebenza ngo-2024) kanye ne-New York igunyaza amazinga e-PFAS angatholakali kumaphrojekthi omphakathi.

I-EU: Ukuvinjelwa kwe-PFAS okuhlongozwayo ngaphansi kwe-REACH kungase kuqale ukusebenza ngo-2025.

Amazinga Wokuhlola:Abakhiqizi basebenzisa i-EPA Method 533 (kumasampula aqinile) noma i-ASTM D7968 ukuze baqinisekise isimo sokungakhokhiswa kwe-PFAS.

Ukuzijwayeza kwemboni:Izinkampani ezifana ne-TenCate Grass kanye ne-SYNLawn zenza kabusha imikhiqizo ye-Synthetic Turf ukuze ihlangabezane nalawa mazinga, ngokuqinisekiswa okuvela eceleni.

Kungani i-PFAS itholakala otshanini bokwenziwa?

Kusukela maphakathi nekhulu lama-20, izimboni ziye zanda ngokwandayo zamukela izithasiselo ze-fluorinated process performance additives (PPAs) njengezijwayelekile kumapulasitiki nokukhiqizwa kwezindwangu. Lezi zengezo, ezihlanganisa ama-fluoropolymers afana nokuphuma kwe-polytetrafluoroethylene kanye nama-fluoroelastomers, afaka amabhondi e-carbon-fluorine (CF) ahlotshaniswa ne-per- kanye ne-polyfluoroalkyl substances (PFAS).

Ngokomlando, ama-PPA ane-fluorinated, ikakhulukazi ezinkampanini zomkhiqizo ezifana ne-3M, abambe iqhaza elikhulu ekuthuthukiseni ukukhiqizwa kotshani bokwenziwa. Zivame ukusetshenziswa ezinqubweni ezifana ne-blade extrusion kanye nama-backing coatings. Lezi zengezo azithuthukisi nje kuphela ukusebenza kahle kwe-polyethylene ne-polypropylene extrusion kodwa futhi zithuthukisa isiphetho esingaphezulu, ukuqina, nokumelana namanzi kwe-turf. Ngokunciphisa i-die buildup nokuvimbela ukuqhekeka kwe-ncibilika, benza lula ukwakhiwa kwemicu efanayo, bandise isikhathi eside somkhiqizo, futhi banciphise izindleko zokukhiqiza. Lezi ntuthuko zibe neqhaza elikhulu ekuhlangabezaneni nesidingo esikhulayo sezixazululo ze-turf ezisebenza kahle kakhulu, ezingalungiswa kahle.

Ubuchwepheshe be-PFAS-Free Synthetic Turf: Enye ye-fluorine Polymer Processing Aids (PPAs)

Izixazululo ze-SILIKE ezingena-fluorine

Ukuze kubhekwane nezinselelo ezihlobene ne-PFAS, i-SILIKE yethule uchungechunge lwe-SILIMER. Lo mugqa womkhiqizo omusha uhlanganisa uhla lwe-100% ehlanzekile ye-PFAS-free kanye ne-fluorine-free polymer processing additives (ama-PPA), kanye nama-masterbatches e-PPA angenayo i-PFAS nangenayo i-fluorine. Kuthuthukiswe kusuka ku-polysiloxane eguquliwe, lezi zindlela ezihlukile azigcini nje ngokuthuthukisa ukuthambisa kanye nezakhiwo zangaphezulu kodwa futhi zikhuthaza indlela ephephile, eqhubekayo ngokuqeda ukusetshenziswa kwezinhlanganisela eziyingozi ze-fluorine. Ngokukhetha uchungechunge lwe-SLIKE SILIMERPFAS-Free PPAs , unganikela endaweni enempilo kuyilapho uzuza ekusebenzeni okuphakeme.

Izinzuzo zochungechunge lwe-SILIMER lwe-PFAS-Free PPAs:

- Ibhekana ngokuphumelelayo nokuqhekeka kwesikhumba (isikhumba sikashaka)
- Yehlisa ukwakheka kokufa, okuholela ekwehliseni isikhathi sokuphumula
- Ithuthukisa ukusebenza kahle, okunomthelela ekusebenzeni kahle kakhulu
- Ithuthukisa izakhiwo zokucubungula jikelele
- Inciphisa ngokuphawulekayo ukukhubazeka kwendawo, okuholela ekuqedeni okuphezulu ngesikhathi sokukhishwa kwe-polyethylene noma ama-polypropylene turf blades.

Ukuthuthukisa Ukusebenza Kwe-Polymer Processing:Izixazululo ze-PPA Zokukhiqiza
Uchungechunge lwe-SILIKE's SILIMER PFAS-Free PPAs abaluleke kakhulu ezimbonini eziningi. Afaneleka ngokukhethekile ukusetshenziswa ku-synthetic turf (utshani bokwenziwa), i-masterbatch esebenzayo, ifilimu yepulasitiki, i-blow molding, extrusion, fibers, amashubhu, amashidi, nezintambo. Lezi zixazululo eziguquguqukayo ze-Polymer Processing Aids zenzelwe ukuhlangabezana nezidingo ezihlukahlukene zokukhiqiza kuyilapho kugcinwa amazinga aphezulu okusebenza.

Ukubhekana nokukhula kokulawula kanye nengcindezi yemaketheqeda i-PFAS kanye nesengezo esisekelwe ku-fluorines kusukela kuzinqubo zabo ze-polymer? Emabhizinisini azibophezele ekukhiqizeni okuvumelana nemvelo, i-SILIKE ihlinzeka ngesixazululo esisebenza kahle, esingena-PFAS—esivumelane ngokuphelele nezidingo zakho.

Ukuze uthole eminye imibuzo esimeme yokukhiqiza, sicela uthinte u-Amy Wang kuamy.wang@silike.cnnoma vakashelawww.siliketech.com
