Nei Vagadziri veSynthetic Turf Vari Kutama Kubva kuPFAS？

Zvinhu zvePer- uye polyfluoroalkyl (PFAS) makemikari ekugadzira anowanzo shandiswa mumaindasitiri akasiyana-siyana, kusanganisira huswa hwekugadzira, nekuda kwehunhu hwawo hunodzivirira mvura, hunodzivirira mavara, uye hunogara kwenguva refu. Zvisinei, kushandiswa kwePFAS muhuswa hwekugadzira kwakakonzera kunetseka kukuru, zvichikonzera shanduko kune dzimwe nzira dzisina PFAS. Heano zvikonzero zvikuru nei vagadziri vari kudzivirira PFAS uye kutsvaga kuri kuenderera mberi kwePFAS-free process performance additives (PPAs) uye dzimwe nzira dzisina fluorine:

1. Njodzi dzehutano

Dambudziko:PFAS, inowanzonzi "makemikari asingaperi" nekuda kwekubatana kwayo necarbon-fluorine, ine chekuita nenjodzi huru dzehutano, kusanganisira kenza, kukanganiswa kwemasoja emuviri, uye matambudziko ekukura. Muhuswa hwekugadzira, PFAS iri mumakapeti, mashizha, kana infill inogona kudyiwa kana kufemerwa, kunyanya nevana kana vatambi vari muminda yakaora uko guruva nezvimedu zvinoburitswa.

Uchapupu:Zvidzidzo, zvakaita semushumo we2022 Environmental Science & Technology, zvakawana huwandu hwePFAS hunoonekwa mumasampuli emate evatambi vanoshandisa minda yekugadzira.

Mhinduro yeIndasitiri:Vagadziri vakuru vava kukoshesa huswa husina PFAS, kunyanya kuzvikoro nenzvimbo dzekutamba, kuderedza mutoro uye kuenderana nenheyo dzebasa rekutarisira.

2. Kukanganiswa Kwezvakatipoteredza: Kudzivirira Kusvibiswa Kwenguva Refu
DambudzikoPFAS haiori zvakasikwa uye haiunganidzike muzvinhu zvipenyu. Mvura inoyerera mumunda wevhu yakaratidzwa kuti inosvibisa mvura.

Chidzidzo Chenyaya:Chidzidzo che2021 Water Research Foundation chakawana PFAS mu78% yemasampuli emvura yepasi pevhu pedyo nemidziyo yekugadzira huswa.

Chiito Chekutonga:Mutemo weCalifornia weSafe Drinking Water and Toxic Enforcement Act (Proposition 65) unoti PFAS inorambidzwa kushandiswa nemutemo.

Hurongwa hweEU hwekunyoresa, kuongorora, kubvumidza uye kurambidza mishonga yemakemikari (REACH) huri kubvisa zvachose PFAS muzvinhu zvinotengeswa nevatengi.

Mhinduro:Masisitimu evhu asina PFAS anobvisa machira ane fluorinated uye anobatana nemafuta anozadza (semuenzaniso, cork, coconut husk) kuderedza kugara kwenguva refu kwezvakatipoteredza.

3. Kumanikidzwa Kwemutemo: Kutevedzera Mutemo Kunosimudzira Kuchinja

Mitemo Yepasi Pose:

US: Nyika dzakadai seCalifornia (Mutemo weMutemo Nhamba 1423, unoshanda muna 2024) neNew York dzinorayira kuti PFAS isaonekwe mumapurojekiti everuzhinji.

EU: Kurambidzwa kwePFAS kuri pasi peREACH kunogona kutanga kushanda panosvika 2025.

Mitemo Yekuyedza:Vagadziri vanoshandisa EPA Method 533 (yemasampuli akasimba) kana ASTM D7968 kuratidza kuti hapana PFAS.

Kugadziriswa kweMaindasitiri:Makambani akaita seTenCate Grass neSYNLawn anogadzirisa zvigadzirwa zveSynthetic Turf kuti zvienderane nezvinodiwa izvi, nekusimbisa makambani echitatu.

Sei PFAS inowanikwa muuswa hwekugadzira?

Kubva pakati pezana remakore rechi20, maindasitiri ave achinyanya kushandisa fluorinated process performance additives (PPAs) seyakajairika mukugadzira mapurasitiki nemachira. Izvi zvinowedzerwa, zvinosanganisira fluoropolymers senge polytetrafluoroethylene derivatives uye fluoroelastomers, zvine carbon-fluorine (CF) bonds dzinobatanidzwa ne per- uye polyfluoroalkyl substances (PFAS).

Kare, maPPA ane fluorine, kunyanya kubva kumakambani emhando dzakadai se3M, akaita basa guru mukusimudzira kugadzirwa kwehuswa hwekugadzira. Anowanzo shandiswa mumabasa akadai sekubvisa blade uye machira ekutsigira. Izvi zvinowedzera hazvingobatsiri chete pakuvandudza kushanda kwe polyethylene ne polypropylene extrusion asiwo zvinovandudza kupenya kwepamusoro, kugara kwenguva refu, uye kuramba mvura kwehuswa. Nekuderedza kuunganidzwa kwemafuta uye kudzivirira kupwanyika kwemvura, zvinoita kuti huswa huve hwakafanana, kuwedzera hupenyu hwechigadzirwa, uye kuderedza mari yekugadzira. Kufambira mberi uku kwave kuri chinhu chakakosha mukuzadzisa kudiwa kuri kukura kwemhinduro dzehuswa dzinoshanda zvakanyanya uye dzisingagadziriswi zvakanyanya.

Tekinoroji yePFAS-Free Synthetic Turf: Imwe nzira inoshandiswa pane fluorine Polymer Processing Aids (PPAs)

Mhinduro dzeSILIKE dzisina fluorine

Kuti vagadzirise matambudziko ane chekuita nePFAS, SILIKE yakatanga SILIMER series. Iyi mhando itsva yezvigadzirwa inosanganisira 100% pure PFAS-free uye fluorine-free polymer processing additives (PPAs), pamwe chete nePFAS-free uye fluorine-free PPA masterbatches. Yakagadzirwa kubva kupolysiloxane yakagadziriswa organically, dzimwe nzira idzi hadzingowedzere mafuta uye hunhu hwepamusoro chete asiwo dzinosimudzira nzira yakachengeteka uye inogara kwenguva refu nekubvisa kushandiswa kwemakemikari ane fluorine anokuvadza. Nekusarudza SLIKE SILIMER seriesPFAS-Free PPAs, unogona kubatsira kune hutano hwakanaka uku uchibatsirwa nekushanda kwepamusoro.

Mabhenefiti eSILIMER series PFAS-Free PPAs:

- Inoshanda zvakanaka pakubvisa ganda rakanyunguduka (sharkskin)
- Inoderedza kuunganidza kwemafuta, zvichiita kuti nguva yekuzorora ideredzwe
- Inovandudza kufambisa kwemagetsi, ichibatsira mukushanda zvakanaka
- Inovandudza hunhu hwese hwekugadzirisa
- Inoderedza zvakanyanya zvikanganiso zvepadenga, zvichiita kuti pave nekupenya kwepamusoro-soro kwenzvimbo panguva yekubuda kwemashizha evhu re polyethylene kana polypropylene.

Kuvandudza Kushanda Kwekugadzira Polymer:Mhinduro dzePPA dzekugadzira
MaPPA eSILIKE's SILIMER series PFAS-Free PPAs akakosha zvikuru mumaindasitiri akasiyana-siyana. Anonyanya kukodzera kushandiswa muhuswa hwekugadzira (huswa hwekugadzira), masterbatch inoshanda, firimu repurasitiki, blow molding, extrusion, fibers, machubhu, masheti, uye tambo. Mhinduro idzi dzePolymer Processing Aids dzinochinjika dzakagadzirirwa kusangana nezvinodiwa zvakasiyana-siyana zvekugadzira uku dzichichengetedza mwero wekushanda kwepamusoro.

Vari kutarisana nekumanikidzwa kuri kukura kwemitemo nemusika kutikubvisa PFAS uye fluorine-based additiveKubva mumaitiro avo epolymer? Kune mabhizinesi akazvipira kugadzira zvinhu zvine hushamwari nezvakatipoteredza, SILIKE inopa mhinduro inoshanda zvikuru, isina PFAS—yakagadzirirwa zvakakwana zvaunoda.
