Makatuʻunga ʻi he fakahokohoko fakamotuʻalea ʻo e taʻofi muimuiʻi (CTI), ʻe lava ke fakafaʻahinga ʻa e ngaahi naunau ʻaofi maluʻi mei fefeka ʻoku fakaʻaongaʻi ʻi he meʻangaue fakaʻuhila ki he tuʻunga ʻe tolu: I, II, mo e IIa, ʻo hange ko ʻene ha ʻi he tepile 1.9. Fakatatau ki he GB/T 4207-2012 “Ngaahi founga ki hono fakapapauʻi ʻo e indices ki hono muimuiʻi ʻo e ʻuhila ʻo e ngaahi naunau maluʻi fefeka,” ʻOku ʻoatu ha fakamaaka ʻo e ngaahi naunau ʻaofi maluʻi mei angamaheni, ʻo hange ko hono fakaikiiki ʻi he tepile 1.10.

Makehe mei he fakafaʻahinga naunau ko ʻeni, kuo pau foki ke feau ʻe he ngaahi naunau ʻaofi maluʻi mei ʻa e ngaahi fie maʻu ki hono fakalele ʻo e ʻea. Kapau ʻoku ngaue ʻaki ʻa e ngaahi meʻangaue fakaʻuhila ki he malu ʻi he ngaahi tuʻunga ʻoku ʻikai fakangofua ʻi hono tuʻunga ngaue, ʻene ngaue lahi taha mafana ʻo e ʻea ʻOku ʻikai totonu ke uesia lahi ʻe he ngaahi koloa fakamisini mo e ʻuhila. Ko ia, ʻOku totonu ke ʻoua naʻa toe siʻi hifo he 20 ° c ʻa e mafana ʻo e naunau ʻaofi maluʻi mei ʻi he mafana ʻo e meʻangaue, pea ʻikai maʻulalo ange ʻi he 80 ° c.

ʻE lava ke fili ʻe he kau ta fakatataa ʻa e ngaahi naunau ʻaofi maluʻi mei totonu ʻo makatuʻunga ʻi he ngaue voltage ʻo e meʻangaue fakaʻuhila mo e ngaahi fie maʻu kehe ʻoku fekauʻaki mo ia. Kapau ʻoku ʻikai feau ʻe he ngaahi naunau ʻoku ha atu ʻa e ngaahi fie maʻu ki he palani, ʻe lava ke siviʻi mo fakamaaka ʻa e ngaahi naunau kehe ʻo hange ko e founga sivi angamaheni (GB/T 4207-2012).
ʻOku mahuʻinga ke fakatokangaʻi ʻoku “ngaahi naunau ʻaofi maluʻi mei fefeka” ʻuhinga ki he ngaahi naunau ʻoku fefeka lolotonga e ngaue. Ngaahi nāunau ʻe niʻihi, ʻa ia ʻoku huhuʻa ʻi he taimi ʻo e meʻakai mo e fakamalohia ʻi hono fakaʻaongaʻi, ʻOku toe lau foki ia ko ha ngaahi naunau ʻaofi maluʻi mei fefeka, hange ko e maluʻi varnishes.
