Shenhai e fakamoʻoni fakaʻauha
ʻOku fakamahinoʻi mai ʻe he fakafaʻahinga ʻo e T4 kuo pau ke ngaue ʻaki ʻe he ngaahi meʻangaue fakaʻuhila ʻa e mafana ʻo e ʻea ʻo ʻikai toe laka hake ʻi he 135 ° c. ʻOku fakaʻaongaʻi ʻa e ngaahi koloa ʻoku ʻi ai ha faʻahinga T6 ʻi he ngaahi kulupu mafana kehekehe, ka ʻoku fenapasi ʻa e ngaahi device T4 mo e T4, T3, T2, mo e ngaahi tuʻunga T1.
| 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 |
Ko e ʻuhinga ʻoku ʻikai faʻa fakaʻaongaʻi ai ʻa e T6 ko e ngaahi meʻangaue lahi, tautautefito kiate kinautolu ʻoku nau fie maʻu ha malohi maʻolunga pe kau ai ʻa e resistive circuits, ʻOku ʻikai ke nau lava ʻo aʻusia ʻa e ngaahi tuʻunga stringent ʻo e ʻea ʻi he fakafaʻahinga ʻo e T6.
