Sodium Hydroxide Granules Caustic Soda Pearl
Sodium hydroxide, nke a na-akpọkarị caustic soda ma mara ya dị ka "Brother's" na Hong Kong n'ihi aha njirimara a.Ọ bụ ngwakọta inorganic na kristal na-acha ọcha na ọnọdụ okpomọkụ nkịtị, yana nrụrụ siri ike.Ọ bụ alkali a na-ahụkarị, ma nwee ọnụnọ ya na ụlọ ọrụ kemịkalụ, metallurgy, ime akwụkwọ, mmanụ ala, akwa akwa, nri, ọbụlagodi ụlọ ọrụ ịchọ mma na ude.
Sodium hydroxide na-agbaze nke ukwuu n'ime mmiri ma na-ahapụ oke okpomọkụ n'ihu mmiri na uzuoku.Mgbe ekpughere ya na ikuku, sodium hydroxide ga-amịkọrọ mmiri dị n'ikuku, ma jiri nwayọọ nwayọọ gbazee mgbe elu dị mmiri, nke a bụ ihe anyị na-akpọkarị "deliquescence" N'aka nke ọzọ, ọ ga-emeghachi omume na carbon dioxide na ikuku ma na-akawanye njọ. .Ya mere, ekwesịrị ịkpachara anya na nchekwa na nkwakọ ngwaahịa sodium hydroxide.Na mgbakwunye na njirimara nke ịbụ soluble na mmiri, sodium hydroxide bụkwa soluble na ethanol, glycerol, ma ọ bụghị na ether, acetone, na mmiri mmiri amonia.Tụkwasị na nke ahụ, ekwesịrị ịmara na ngwọta mmiri sodium hydroxide bụ nke siri ike alkaline, astringent na griiz, ma nwee ike corrosivity.
Enwere ike kewaa sodium hydroxide nke a na-ere n'ahịa ka ọ bụrụ soda siri ike siri ike na mmiri soda dị ọcha.N'ime ha, soda siri ike siri ike dị ọcha na-acha ọcha, n'ụdị ngọngọ, mpempe akwụkwọ, mkpanaka na urughuru, na kenkuwa;Mmiri mmiri dị ọcha caustic soda enweghị agba na mmiri mmiri doro anya.

Ugbu a, anyị ga-ewebata ngwa nke sodium hydroxide n'ụzọ dị iche iche n'ụzọ zuru ezu.
Dị ka ihe akụrụngwa alkaline siri ike, enwere ike iji sodium hydroxide mepụta borax, sodium cyanide, formic acid, oxalic acid, phenol, wdg, ma ọ bụ jiri ya na ụlọ ọrụ kemịkalụ inorganic na ụlọ ọrụ kemịkalụ organic.
1)Inorganic chemical ụlọ ọrụ:
① A na-eji ya emepụta salts sodium dị iche iche na metal hydroxides dị arọ.
② A na-eji ya eme ihe maka mkpochapụ nke ore.
③ Gbanwee uru pH nke ngwọta mmeghachi omume dị iche iche.
2)Ụlọ ọrụ kemịkalụ Organic:
① A na-eji sodium hydroxide maka mmeghachi omume saponification iji mepụta etiti anionic nucleophilic.
