He mea hoʻohuihui kemika koʻikoʻi ka sodium hydrosulfide
2026-06-01
sodium hydrosulfide he mea maka kemika koʻikoʻi a me ka huahana ʻaoʻao, a ke kū nei kāna kaʻina hoʻomaloʻo a me ka hoʻonui ʻana i nā pilikia kūikawā e like me ka corrosive ikaika a me ka ʻike wela kiʻekiʻe.
Ka Nānā ʻana i nā ʻAno Kūikawā o ke Kaʻina Hana Hoʻoheheʻe Sodium Hydrosulfide
He ʻokoʻa loa ka mahu ʻana o nā hopena sodium hydrosulfide mai ko nā paʻakai maʻamau, ʻelua mau ʻano nui: nā waiwai o nā mea a me nā koi hana.
Ma ke ʻano kemika, hoʻoheheʻe koke ʻia ka sodium hydrosulfide i nā mahana kiʻekiʻe, e hana ana i ke kinoea hydrogen sulfide a me ka sodium hydroxide. ʻAʻole wale kēia hopena e hoʻopau ai i ka nalowale ʻana o nā mea hana akā alakaʻi pū kekahi i ka palaho nui o nā lako. Hōʻike nā ʻikepili hoʻokolohua e piʻi nui ana ka nui o ka hydrolysis o ka sodium hydrosulfide ke ʻoi aku ka mahana ma mua o 80°C, e koi ana i ka kaohi pololei o nā mahana hana i loko o ka ʻōnaehana hoʻoheheʻe.
Ma ke kino, he alkaline ikaika a ʻānai loa nā hopena sodium hydrosulfide, e kau ana i nā koi koʻikoʻi ma nā mea hana. Hoʻomohala nā kila kila maʻamau i ka pitting corrosion a me ka stress corrosion cracking ma hope o ka hoʻopili lōʻihi ʻana, e pono ai ka hoʻohana ʻana i nā alloys kūikawā a i ʻole nā ʻenehana lining. I kēia manawa, hana nā ion sulfide i loko o ka hopena me nā ʻili metala e hana i kahi papa FeS wehe, e hoʻolalelale hou aku i ka corrosion. Hōʻike ka ʻikepili hana ʻaʻole iʻoi aku ka lōʻihi o ke ola lawelawe o nā lako kila kalapona pale ʻole i loko o kahi sodium hydrosulfide ma mua o 6 mau mahina.
ʻO nā ʻano kino maʻamau o nā hopena sodium hydrosulfide e komo pū ana: kahi piʻi ʻana o ka paila he 15-25°C no kahi hopena hoʻohuihui 30%; kahi helu pala o 0.5-2.0 mm/makahiki no ke kila kila 316L ma 80°C; kahi helu hydrolysis o 3-8% i kēlā me kēia hola ma 90°C ma lalo o ke kaomi lewa; a me kahi mahana crystallization o 40-60°C no nā hopena saturated.
He ʻokoʻa loa ka mahu ʻana o nā hopena sodium hydrosulfide mai ko nā paʻakai maʻamau, ʻelua mau ʻano nui: nā waiwai o nā mea a me nā koi hana.

ʻO ka Sodium Hydrosulfide (NaHS)
ʻO Zibo Anhao Chemical Co., Ltd. kahi mea hoʻolako loea o ka Sodium Hydrosulfide kiʻekiʻe, kahi kemika inorganic i hoʻohana nui ʻia me CAS No. 16721-80-5. Loaʻa kā mākou huahana ma nā ʻano flake paʻa a me nā ʻano wai, me ka maʻemaʻe kiʻekiʻe, nā waiwai kemika paʻa a me ka solubility maikaʻi i ka wai.
Hoʻohana nui ʻia ia ma nā ʻoihana he nui: ma ke ʻano he mea lana i ka hana ʻeli ʻana no ka hana ʻana i ka metala ʻole-ferrous; he mea kōkua dehailing a me ka tanning i ka ʻoihana ʻili; he mea hoʻemi a me ke kōkua dye i nā kahua lole a me ka dyeing; a he mea maka koʻikoʻi no ka synthesis kemika, ka mālama ʻana i ka wai ʻino a me ka hana pepa.
Hoʻohana mākou i nā kūlana kaohi maikaʻi koʻikoʻi a hāʻawi i nā hoʻonā hoʻopili maʻalahi. Me ka lawa ʻana o ka waihona a me ka logistics kūpono, hiki iā mākou ke hoʻokō i nā kauoha nui a hāʻawi i nā waiwai i ka manawa kūpono. Welina mai i nā mea kūʻai aku honua e hoʻokaʻaʻike mai iā mākou no ke alu like ʻana.
