Shenhai e fakamoʻoni fakaʻauha
ʻI he malaʻe ʻo e meʻangaue ki he fakaʻauha, ʻOku fakapapauʻi ʻa e malu ʻi he fakafaʻahinga ʻo e ʻea ʻo e meʻangaue. Ko e fakafaʻahinga ʻo e T6, ʻoku ne fakahaaʻi ʻa e “mafana ʻo e ʻea,” fakafofongaʻi ʻa e faʻahinga malu taha ʻi he ngaahi meʻa ni. ʻOku fakapapauʻi ʻe he fakafaʻahinga ko ʻeni ʻoku maʻulalo feʻunga ʻa e mafana ʻo e meʻangaue ke taʻofi igniting ngaahi kasa velangofua, Naʻa mo kinautolu ʻoku ʻi ai ha ignition maʻulalo. ʻI he tafaʻaki ʻe taha, T1, mo e tafaʻaki maʻolunga taha kuo fakangofua mafana ʻo e ʻea, ʻOku ne ʻomi ʻa e tuʻunga fakatuʻutamaki taha ʻi he ngaahi ʻatakai ʻoku maumau.
| Kulupu mafana ʻo e meʻangaue fakaʻuhila | Lahi taha e mafana ʻo e meʻangaue fakaʻuhila (° C) | Kasa/mao ignition e ʻea (° C) | Tuʻunga ʻo e mafana ʻo e meʻangaue |
|---|---|---|---|
| T1 | 450 | >450 | T1 ~ T6 |
| T2 | 300 | >300 | T2 ~ T6 |
| T3 | 200 | >200 | T3 ~ T6 |
| T4 | 135 | >135 | T4 ~ T6 |
| T5 | 100 | >100 | T5 ~ T6 |
| T6 | 85 | >85 | T6 |
ʻI he meʻangaue ki he fakamoʻoni fakaʻauha, ʻOku ʻikai ko ha konga ʻo e tokanga ʻa e tefitoʻi meʻa ʻoku fai ki ai e tokanga, ka ko e fakangatangata ʻo e ivi ne tukuange mei he ngaahi konga ʻo e maumau ke taʻofi igniting ngaahi kasa ʻi he fakafepakiʻi atmospheres. Hange ko e "fokotuʻutuʻu ʻo e ngaahi fakahinohino pau ki he ngaahi meʻa fakaʻuhila ʻi he ngaahi ʻatakai fakatuʻutamaki mo e afi", ʻOku tuʻu ʻa e tuʻunga T6 ko e fakafaʻahinga malu taha. ʻOku ola lelei ʻa e ngaahi device mo e fakafaʻahinga T6 ʻi hono fakaʻehiʻehi mei he lolotonga, tautautefito ʻi he ngaahi ʻatakai ʻoku ignition maʻulalo combustible ngaahi kasa, ke ʻoua naʻa lau ʻa kinautolu ʻoku maʻolunga ange ʻenau ignition.
