Dagewar harshen wuta shine fasaha mai mahimmancin aminci da aka ƙera don rage ƙonewar yadudduka, rage ƙonewa da yaduwar harshen wuta, ta haka ne ceton rayuka da dukiyoyi. Jiyya na kashe wuta (FR) suna aiki ta hanyoyi daban-daban na sinadarai da na jiki don katse zagayen konewa a matakai daban-daban: dumama, bazuwar wuta, kunnawa, ko yada harshen wuta.
Mahimman Hanyoyi:
1. Cooling: Wasu FRs suna ɗaukar zafi, suna rage yawan zafin jiki a ƙasa da wurin kunnawa.
2. Samar da Char: Phosphorus ko tsarin tushen nitrogen suna haɓaka samar da kariya mai kariya, mai sanya shingen caja a maimakon ƙona wuta.
3. Dilution: FRs bazuwa don saki iskar gas maras ƙonewa (kamar tururin ruwa, CO₂, nitrogen), diluting oxygen da gas gas kusa da harshen wuta.
4. Radical Trapping: Halogenated mahadi (ko da yake ƙara ƙuntatawa) sakin radicals wanda ke tsoma baki tare da halayen sarkar exothermic a cikin yankin harshen wuta.
Nau'in Jiyya:
Dorewa: Chemically bonded to fibers (na kowa don auduga, polyester blends), tsira da yawa wankewa. Misalai sun haɗa da Pyrovatex® don maganin cellulose ko tushen THPC.
Mara Dorewa/Semi-Durable: Ana amfani da shi ta hanyar sutura ko suturar baya (sau da yawa don roba, kayan kwalliya, labule). Waɗannan na iya fita ko ragewa tare da tsaftacewa.
