Hoʻohana
hoʻohanaʻia ma kaʻoihana mineng e like me ka inoibitor, curing agent, e lawe ana i ka luna
hoʻohanaʻia ma ka hui kikowaena pilikino a me ka hoʻomākaukauʻana i nā hoʻohui sulfur dye hoʻohui.
Hoʻohanaʻia i loko o kaʻoihana mika e like me ka bleaching, e like me ka destulfurizing a me he mea hana dechlorinating
hoʻohanaʻia ma ka pulp a me kaʻoihana pepa.
hoʻohanaʻia i loko o ka mālama waiʻana e like me ka oxygen oxygen scavenger.
ʻO nā mea'ē aʻe i hoʻohanaʻia
♦ Ma ke kiʻi kiʻi kiʻi e pale ai i nā hoʻonā hoʻomohalaʻana mai ka oxidation.
♦ Hoʻohana ia i ka hanaʻana o nā mea kanu a me nā mea kanu lāʻau lapaʻau'ē aʻe.
♦ E hoʻohanaʻia ma nā noi'ē aʻe e pili ana i ka flotation o ka flotation
Hana lima a mālama
A.Precalitions no ka lawelaweʻana
1. Hoʻomoʻaʻia ka 1.handling ma kahi wahi kūponoʻole.
2.Wear kūpono i nā mea pale pale pale.
3.Avoid pili me nāʻili a me nā maka.
4.Keep ma kahi o ka wela / sparks / wehe i nā flames / wela wela.
5.Kike i nā hana mua e kū'ē i nā mea hoʻopiʻi static.
B.precations no ka mālamaʻana
Ua pani paʻaʻia nā mea kūʻai aku 1.
2.keep coainers ma kahi maloʻo maloʻo a maikaʻi a maikaʻi hoʻi.
3.Keep mamao mai ka wela / sparks / wehe i nā flames / wela wela.
4. Hale kūʻai aku i nā mea waiwaiʻole a me nā mea kanu meaʻai.
ʻO nā waiwai pilikino a me ke olakino o ka sodium hydrosulpidide (nahs)
1.ʻO nā waiwai pilikino
ʻO ka hiʻohiʻona:ʻO Soddium hydrosulfide ka mea maʻamau a iʻole ke aniani keʻokeʻo a iʻole ka māmā o ke melemele crystalline. E lilo paha ia i kalaʻole i ka melemele, cliquescent crystal me ka hydrogen sulfide sulfide.
Menging Point:ʻO ka hoʻokaʻawaleʻana o keʻano o keʻano o ka sodium sodium hydrosulfide he 350 ° C; ʻO keʻano o ka menking o ka hydrate he haʻahaʻa, ma 52-54 ° C. Eia naʻe, hōʻike kekahi data data e hōʻike ana i keʻano o ka'ōpū o ka sodium hydrosulfide is 55 ° C.
Density:ʻO keʻano o ka sodium hydrosulfide he 1.79 g / cm³, a iʻole 1790 kg / m³.
ʻO ka hopena: Sodium hydrosulfide e hoʻomoʻa maʻalahi i ka wai a me ka waiʻona, a me kona hopena a me ka alkaline. Wahi a kekahi mau ikepili,ʻo ka palekana o ka sodium hydrosulfide ma ka wai he 620g / l at 20 ° C.
2.ʻO nā waiwai kaulike
ʻO ka aceity a me Alkalin
ʻO ka hopena me Acid: Sodium hydrosulfide e hoʻokuʻu i ka goldide sulfide solfide i ka wā e hālāwai ai me ka acid. ʻO ke hoʻohālikelike e like: nahs + h + → → H2S ↑.
Hiki i keʻano me Sulfur:ʻO SODIum hydrosulfide ke hana me ka sulfur e hana i nā polysulfie, ka hopena hopena.
ʻO ka hōʻemiʻana:ʻO Sodouum hydrosulfide kahi maʻamau maʻamau e hōʻemi ana i nā mea e hiki ke hōʻemi i nāʻano redox redox me nā mea he nui.
3. Nā waiwai'ē aʻe
ʻO ka paʻaʻana:ʻO SODIUM Hydrosulfide he hui pūʻia, akā he hygroscopic. I ka manawa like, he mea paʻa ia a iʻole e hoʻomālamalama i ka lewa.
ʻO ka mea hana No laila, pono e ukuʻia ka manaʻo kūikawā i ka pale palekana i ka wā e hoʻohana ai a mālama.
I kēia manawa,ʻoi aku ka maikaʻi o kaʻoihana i nā mākeke ma waho a me nā'ōlaʻi honua.
I nā makahikiʻekoluʻekolu, ua kūpaʻa mākou e lilo i kahiʻoihana ma luna o ka hana aʻoaʻo ma keʻano he nui a me ka hanaʻana i kahi kula nani.
