Mea hoʻolako momi kopa

ʻO ka wehewehe pōkole:

ʻO nā momi kopaʻa (ʻike pū ʻia ʻo ka sodium hydroxide, ka soda, NaOH, ka sodium hydrate, a i ʻole ka Sodagrain) he mau poʻi keʻokeʻo o ka soda me kahi ʻala ʻike ʻole ʻia.Hiki ke hoʻoheheʻe ʻia i ka wai, me ka hoʻokuʻu ʻana o ka wela, a paʻa ma lalo o nā kūlana maʻamau.

Hoʻohana Huahana

ʻO nā momi koʻikoʻi koʻikoʻi koʻikoʻi ke hoʻohana ʻia i nā ʻoihana he nui o ka honua.ʻO ke koi kiʻekiʻe loa no ka soda caustic mai ka ʻoihana pepa kahi i hoʻohana ʻia ai i ka pulping a me ka hana bleaching.Ke koi ʻia nei lākou i ka ʻoihana alumini no ka hoʻopau ʻana o ka soda caustic i ka bauxite ore, ʻo ia ka mea maka i ka hana alumini.ʻO kekahi hoʻohana nui no ka soda caustic ʻo ia ka hana kemika no ka mea ʻo ka soda caustic kahi meaʻai kumu no ka nui o nā huahana i lalo me nā solvents, plastics, fabrics, adhesives etc.

Hoʻohana pū ʻia nā momi kopa caustic i ka hana kopa i ka wā e hoʻoulu ai i ka saponification o nā aila meaʻai a i ʻole nā ​​momona e pono ai no ka hana ʻana i ke kopa.He kuleana ko lākou i ka ʻoihana kinoea maoli kahi i hoʻohana ʻia ai ka sodium hydroxide e kōkua i ka hana ʻana a me ka hana ʻana i nā huahana petroleum a hiki ke hoʻohana ʻia i ka ʻoihana textile kahi i hoʻohana ʻia ai i ka hana kemika o ka pulupulu.

He mau mea hoʻohana liʻiliʻi nō hoʻi ka soda caustic.Hiki ke hoʻohana ʻia no ka etching aluminika, ka nānā ʻana i nā kemika a me ka mea huki pena.He mea ia i loko o ka nui o nā huahana hale e like me ka paipu a me ka hoʻomaʻemaʻe wai, ka umu hoʻomaʻemaʻe a me nā huahana hoʻomaʻemaʻe home.
