I-textile flame retardancy iwubuchwepheshe bokuphepha obubalulekile obuklanyelwe ukunciphisa ukuvutha kwezindwangu, ukunciphisa ukuvutha nokubhebhetheka kwelangabi, ngaleyo ndlela kusindise izimpilo nempahla. Ukwelashwa kwe-flame retardant (FR) kusebenza ngezindlela ezihlukahlukene zamakhemikhali nezomzimba ukuze kuphazamise umjikelezo wokusha ezigabeni ezihlukene: ukushisisa, ukubola, ukuthungela, noma ukusakazeka komlilo.
Izindlela Eziyinhloko:
1. Ukupholisa: Amanye ama-FR adonsa ukushisa, ehlisa izinga lokushisa lendwangu ngaphansi kwendawo yokuthungela.
2. Ukwakhiwa Kwezinhlamvu: I-Phosphorus noma i-nitrogen-based systems ikhuthaza ukwakheka kokuvikela, ungqimba lwe-char oluvikelayo esikhundleni sezivunguvungu ezivuthayo.
3. I-Dilution: Ama-FR ayabola ukuze akhiphe amagesi angashi (njengomhwamuko wamanzi, i-CO₂, i-nitrogen), ahlanza umoya-mpilo namagesi kaphethiloli eduze nelangabi.
4. I-Radical Trapping: Inhlanganisela ye-halogenated (nakuba ikhawulelwa ngokuya ngokuya) ikhulula ama-radicals aphazamisa ukusabela kweketango elishisayo endaweni yelangabi.
Izinhlobo Zokwelashwa:
Ihlala isikhathi eside: Iboshwe ngamakhemikhali kumafayibha (okujwayelekile ukotini, imixube ye-polyester), isaphila lapho iwashwa kaningi. Izibonelo zifaka i-Pyrovatex® ye-cellulose noma ukwelashwa okusekelwe ku-THPC.
Okungahlali isikhathi eside/okungahlali isikhathi eside: Kusetshenziswa ngezimbotshana noma ngezingubo ezingemuva (ngokuvamile okokwenziwa, i-upholstery, amakhethini). Lezi zingase ziphume noma zinciphe ngokuhlanza.
I-Inherent FR Fibers: Ama-Fibers afana nama-aramids (Nomex®, Kevlar®), modacrylic, noma ama-FR rayons/viscose athile anokumelana nelangabi okwakhelwe esakhiweni sawo samangqamuzana.
Izicelo zibalulekile:
Izingubo zokuvikela izicishamlilo, amasosha, abasebenzi bezimboni.
Ifenisha efakwe upholstered, omatilasi, namakhethini ezindlini nezakhiwo zomphakathi.
Ingaphakathi lezokuthutha (izindiza, izitimela, izimoto).
Okhaphethi namatende.
Izinselelo Nokucatshangelwa:
Ukulinganisa ukusebenza kwe-FR ephezulu nokunethezeka, ukuqina, izindleko, futhi ikakhulukazi umthelela wendawo/wezempilo kubalulekile. Imithetho (efana ne-California TB 117, NFPA 701, EU REACH) ihlezi iguquguquka, iqhubekisela phambili ukuqanjwa okuholela ezixazululweni ezisimeme, ezingenabuthi, nezisebenzayo ezingena-halogen. Ucwaningo lugxile ku-bio-based FRs kanye ne-nanotechnology ukuze kuzuzwe izindwangu eziphephile, ezisebenza kahle ngekusasa elikwazi ukumelana nomlilo.
