Ko e afi fakatuʻutamaki ʻo e ʻAlaminiume Magnesium efu ko e kalasi A

Fakatatau ki he “Katiloka ʻo e ngaahi kemikale fakatuʻutamaki” (GB12268), ʻoku to ʻa e efu magnesium ʻalaminiume ʻi he faʻahinga 4 ko ha meʻa ʻoku velangofua, fakahehema ke ignition mo e afi ʻi he taimi ʻoku fehangahangai ai mo e hauhau.

Hange ko e GB50016-2006 “Kouti maluʻi ʻo e afi ki hono faʻufaʻu ʻo e fale,” ʻOku fakafaʻahinga ʻa e ngaahi meʻa ʻoku ne fakatupu ha vela ʻoku tuʻu fakatuʻutamaki ko e kalasi A. Ko e ngaahi meʻa ʻeni ʻe lava ke ne taʻofi ʻa e mafana ʻo e loki pe fakaulo pe ʻita vave ʻi he oxidation ʻi he ʻea. Ngaohi ʻo e ngaahi naunau hange ko e kalasi kuo pau ke muimui ʻa e ngaahi meʻa fakatuʻutamaki ki ha tuʻunga malu siʻisiʻi taha ʻo e tuʻunga malu 1 pe 2. Neongo ʻoku fakaʻaongaʻi ʻa e ngaahi fale talanoa fakavahaʻa-taʻu ʻi he taimi ʻoku fie maʻu ai, fokotuʻu atu ha ngaahi fale fungavaka taha, pea ʻoku ʻikai ngofua ke fakaʻaongaʻi ʻa e basements pe sub-basements.
