Textile flame retardancy ndiyo yakakosha kuchengetedza tekinoroji yakagadzirirwa kudzikisa kupisa kwemachira, kunonoka kupisa uye kupararira kwemurazvo, nekudaro vachiponesa hupenyu nemidziyo. Flame retardant (FR) marapirwo anoshanda kuburikidza neakasiyana makemikari uye emuviri nzira kukanganisa kutenderera kwekupisa pamatanho akasiyana: kupisa, kuora, kubatidza, kana kupararira kwemurazvo.
Makiyi Mechanism:
1. Kutonhodza: Mamwe maFR anotora kupisa, achidzikisa tembiricha yejira pazasi pekupisa.
2. Char Formation: Phosphorus kana nitrogen-based systems inokurudzira kuumbwa kwekudzivirira, insulating char layer panzvimbo yezvinopisa zvinopisa.
3. Dilution: FRs inoora kuti isunungure magasi asingabatiki (semhute yemvura, CO₂, nitrogen), diluting okisijeni uye magasi emafuta pedyo nemurazvo.
4. Radical Trapping: Halogenated compounds (kunyangwe ichiwedzera kurambidzwa) inoburitsa radicals inovhiringidza exothermic cheni maitiro munzvimbo yemoto.
Mhando dzeMarapirwo:
Yakasimba: Kemikari yakasungirirwa kune fiber (yakajairika yekotoni, polyester blends), inorarama yakawanda washing. Mienzaniso inosanganisira Pyrovatex® ye cellulose kana THPC-based marapirwo.
Haisi-Yakasimba / Semi-Yakasimba: Inoshandiswa kuburikidza nekuputira kana kumashure-kupfeka (kazhinji kune synthetics, upholstery, maketeni). Izvi zvinogona kubuda kunze kana kuderedza nekuchenesa.
Inherent FR Fibers: Fibers senge aramids (Nomex®, Kevlar®), modacrylic, kana mamwe maFR rayons/viscose ane murazvo wemoto wakavakirwa muchimiro chavo chemolecular.
Zvikumbiro zvakakosha:
Zvipfeko zvekudzivirira zvevanodzima moto, mauto, vashandi veindasitiri.
Fenicha yakasimudzwa, matiresi, uye maketeni mudzimba nezvivakwa zvavose.
Zvifambiso zvemukati (ndege, zvitima, mota).
Makapeti nematende.
Zvinetso & Zvinotarisirwa:
Kuenzanisa yakakwira FR kuita nekunyaradza, kusimba, mutengo, uye kunyanya kwezvakatipoteredza / hutano kukanganisa kwakakosha. Mitemo (seCalifornia TB 117, NFPA 701, EU REACH) inogara ichishanduka, ichityaira hunyanzvi hwakananga kune yakagadzikana, isina chepfu, uye inoshanda isina halogen-isina mhinduro. Tsvagiridzo inotarisa pane bio-based FRs uye nanotechnology kuwana akachengeteka, epamusoro-kuita machira kune remangwana rinosimba moto.
