HOʻohana 'ē aʻe

♦ I ka ʻoihana kiʻi e pale i nā mea hoʻomohala mai ka oxidation.
♦ Hoʻohana ʻia ia i ka hana ʻana i nā kemika a me nā mea ʻē aʻe.
♦ Hoʻohana ʻia ia i nā noi ʻē aʻe e like me ka hoʻoheheʻe ʻana o ka ʻaila, ka hoʻihoʻi ʻana i ka ʻaila, ka mālama ʻana i ka meaʻai, ka hana ʻana i nā mea pena, a me ka mea holoi.

ʻO ka sodium sulfide (Na2S), ʻike ʻia hoʻi he alkali ʻala, pōhaku sulphide, sodium sulfide, soda ʻala.ʻO nā huahana maʻemaʻe Anhydrous he mau kristal keʻokeʻo equiaxed.ʻAiʻino a me ka deliquescent;Hiki ke hoʻoheheʻe ʻia i ka wai, he alkaline ka hopena;ʻO ka hoʻoheheʻe ʻana i ka ʻakika e hana i ka hydrogen sulfide;E maʻalahi e oxidize i ka ea.Loaʻa i nā huahana ʻoihana nā wai like ʻole o ka crystallization (Na2S•xH2O), ma kahi o 60% sodium sulfide, ma muli o ka liʻiliʻi o nā haumia he melemele māmā a ʻulaʻula paha.Aia nā huahana i loko o ka poloka, flake a me ke ʻano granular.Hoʻohana nui ʻia e like me ka mea hoʻoheheʻe ʻili maka, ka mea kuke pulp, nā mea hoʻoheheʻe vulcanized, nā mea hoʻoheheʻe hoʻoheheʻe ʻana, nā mea hoʻoheheʻe lole lole, nā mea flotation oka, hiki ke hoʻohana ʻia e like me ka viscose fiber desulfurizer a me ka hana ʻana o ka sodium hydrogen sulfide a me ka sodium polysulfide maka. .

Sodium sulphide - Hoʻohana nui

Hoʻohana ʻia no ka hana ʻana i ka wai sulfide, ka ʻili depilation agent, ka hoʻoheheʻe metala, ke kiʻi, ka rayon denitrification a pēlā aku.Hoʻohana nui ʻia i ka hana ʻili, ka hana pākaukau, ka mālama ʻana i ka wai, ka hana ʻana i ka pepa, ka hoʻoheheʻe ʻana o ka mineral, ka hana ʻana i ka wai, nā intermediates organik, ka paʻi ʻana a me ka waihoʻoluʻu, lāʻau lapaʻau, monosodium glutamate, fiber artificial, plastic engineering kūikawā, polyphenylene sulfide, polyalkali rubber, hoʻohana ʻia i ka ka hana ʻana o ka sodium thihydride, sodium polysulfide, sodium thiosulfate, a me nā mea ʻē aʻe, aia kekahi hoʻohana i ka ʻoihana koa.

Hoʻohana ʻia ma ke ʻano he reagent analytical a ma ke ʻano he precipitant no ka cadmium a me nā ion metala ʻē aʻe.Hoʻohana pū ʻia i ke kiʻi, flotation mineral, mālama metala, zinc a me cadmium plating.No ka hana ʻana i nā dyes, sulfide, a hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe oka, mea hoʻoneʻe lauoho ʻili, mea kuke pepa.

① I ka ʻoihana dye no ka hana ʻana i nā dyes sulfurized, sulfurized green, sulfurized blue or dye intermediates reducing agent, mordant, etc.

② Hoʻohana ʻia ma ke ʻano he flotation agent no nā ores i ka ʻoihana metallurgy nonferrous.

③ Mea hoʻoneʻe hulu ma ka ʻoihana ʻili.

(4) ʻoihana pepa i ka mea kuke pepa.

Hoʻohana ʻia ka sodium sulfide i ka hana ʻana i ka sodium thiosulfate, sodium polysulfide, sodium sulfide a me nā huahana ʻē aʻe.

Hoʻohana nui ʻia ʻo ⑥ i ka textile, pigment, rubber a me nā ʻoihana ʻoihana ʻē aʻe.
