Ukuvimbela ilangabi lendwangu ubuchwepheshe obubalulekile bokuphepha obuklanyelwe ukunciphisa ukusha kwezindwangu, ukunciphisa ukusha kanye nokusabalala kwelangabi, ngaleyo ndlela kusindise izimpilo kanye nempahla. Ukwelashwa okuvimbela ilangabi (FR) kusebenza ngezindlela ezahlukahlukene zamakhemikhali nezomzimba ukuphazamisa umjikelezo wokushisa ezigabeni ezahlukene: ukushisa, ukubola, ukusha, noma ukusabalala kwelangabi.
Izindlela Eziyinhloko:
1. Ukupholisa: Amanye ama-FR amunca ukushisa, ehlisa izinga lokushisa lendwangu ngaphansi kwephuzu lokushisa.
2. Ukwakheka Kwe-Char: Izinhlelo ezisekelwe ku-phosphorus noma i-nitrogen zikhuthaza ukwakheka kwesendlalelo se-char esivikelayo nesivikelayo esikhundleni sezinto ezivuthayo ezivuthayo.
3. Ukuncibilikisa: Ama-FR ayabola ukuze akhiphe amagesi angashi (njengomhwamuko wamanzi, i-CO₂, i-nitrogen), ancibilikisa umoya-mpilo namagesi kaphethiloli eduze kwelangabi.
4. Ukudoba Okukhulu: Ama-halogenated compounds (nakuba encishisiwe ngokwandayo) akhipha ama-radical aphazamisa ukusabela kwe-exothermic chain endaweni yomlilo.
Izinhlobo Zokwelashwa:
Ihlala isikhathi eside: Ihlanganiswe ngamakhemikhali nemicu (evamile kukotini, ingxube ye-polyester), isinda ekuhlanzweni okuningi. Izibonelo zifaka phakathi i-Pyrovatex® yokwelapha nge-cellulose noma nge-THPC.
Ayihlali isikhathi eside/Ihlala isikhathi eside kancane: Isetshenziswa ngezimbozo noma ngezimbozo zangemuva (ngokuvamile zezinto zokwenziwa, upholstery, amakhethini). Lokhu kungaphuma noma kunciphe lapho kuhlanzwa.
Ama-FR Fibers Angokwemvelo: Ama-fibers afana nama-aramid (Nomex®, Kevlar®), ama-modacrylic, noma ama-FR rayons/viscose athile anokumelana nomlilo okwakhelwe esakhiweni sawo sama-molecule.
Izicelo zibalulekile:
Izingubo zokuzivikela zabacimi bomlilo, amasosha, abasebenzi basezimbonini.
Ifenisha efakwe upholstery, omatilasi, namakhethini emakhaya nasezindlini zomphakathi.
Izinto zangaphakathi zokuhamba (izindiza, izitimela, izimoto).
Amakhaphethi namatende.
Izinselele kanye Nokucatshangelwa:
Ukulinganisela ukusebenza okuphezulu kwe-FR nenduduzo, ukuqina, izindleko, kanye nomthelela omkhulu kwezemvelo/zempilo kubalulekile. Imithethonqubo (njenge-California TB 117, i-NFPA 701, i-EU REACH) iyaqhubeka nokuguquka, iqhubekisela phambili ukusungula izinto ezintsha ezixazululweni ezizinzile, ezingenabo ubuthi, nezisebenzayo ezingenayo i-halogen. Ucwaningo lugxile kuma-FR asekelwe ku-bio kanye ne-nanotechnology ukuze kufezwe izindwangu eziphephile nezisebenza kahle zekusasa elimelana nomlilo.
