Ho fokotsa lelakabe la masela ke theknoloji ea bohlokoa ea polokeho e etselitsoeng ho fokotsa ho tuka ha masela, ho fokotsa ho chesa le ho hasana ha lelakabe, kahoo ho pholosa bophelo le thepa. Litlhare tsa Flame retardant (FR) li sebetsa ka mekhoa e fapaneng ea lik'hemik'hale le ea 'mele ho sitisa potoloho ea mollo ka mekhahlelo e fapaneng: ho futhumatsa, ho bola, ho hotetsa kapa ho phatlalatsoa ha lelakabe.
Mekhoa ea Bohlokoa:
1. Ho pholisa: Li-FR tse ling li monya mocheso, li theola mocheso oa lesela ka tlas'a ntlha ea ho tima.
2. Tlhahiso ea Char: Phosphorus kapa nitrogen-based systems e khothalletsa ho thehoa ha lesela le sireletsang, le sireletsang la char ho e-na le li-volatiles tse tukang.
3. Dilution: Li-FR li senyeha ho lokolla likhase tse sa cheng (joaloka mouoane oa metsi, CO₂, nitrogen), ho hlapolla oksijene le likhase tsa mafura haufi le lelakabe.
4. Radical Trapping: Lik'hemik'hale tse halogenated (le hoja li ntse li thibetsoe ka ho eketsehileng) li lokolla li-radicals tse sitisang tšebetso ea ketane ea exothermic sebakeng sa lelakabe.
Mefuta ea Kalafo:
E tšoarella: E kopantsoe ka lik'hemik'hale ho likhoele (tse tloaelehileng bakeng sa k'hothone, li-polyester blends), li ntse li le teng ka makhetlo a mangata. Mehlala e kenyelletsa Pyrovatex® bakeng sa kalafo ea cellulose kapa THPC.
E sa tšoarelleng / e tšoarellang ka nako e telele: E sebelisoa ka ho roala kapa ka morao (hangata bakeng sa li-synthetics, upholstery, likharetene). Tsena li ka 'na tsa fokotseha kapa tsa fokotseha ka ho hloekisa.
Inherent FR Fibers: Fibers tse kang aramids (Nomex®, Kevlar®), modacrylic, kapa tse ling tsa FR rayons/viscose li na le khanyetso ea malakabe e hahiloeng ka har'a sebopeho sa tsona sa limolek'hule.
Lisebelisoa li bohlokoa:
Liaparo tse sireletsang bakeng sa bo-ralitima-mollo, sesole, basebetsi ba indasteri.
Thepa ea ka tlung, materase le likharetene tse katiloeng malapeng le meahong ea sechaba.
Libaka tsa lipalangoang (lifofane, literene, likoloi).
Likhapete le litente.
Mathata le Mathata:
Ho leka-lekanya ts'ebetso e phahameng ea FR le boiketlo, nako e telele, litšenyehelo, haholo-holo phello ea tikoloho / bophelo bo botle ke habohlokoa. Melawana (joaloka California TB 117, NFPA 701, EU REACH) e lula e fetoha, e lebisa boqapi bo lebisang ho tharollo e tšoarellang, e seng chefo, le e sebetsang e se nang halogen. Patlisiso e tsepamisitse maikutlo ho li-FR tse thehiloeng ho li-bio le nanotechnology ho fihlela masela a bolokehileng, a sebetsang hantle bakeng sa bokamoso bo mamellang mollo.
