Sodium Hydrosulfite 90%, Yagadzirira Kutumirwa ~

Mashandisirwo:
1. Kushandiswa kwe sodium hydrosulfite kwakakura zvikuru, kunosanganisira kuderedza kudhaya, kuchenesa kuderedza, kudhinda uye kubvisa ruvara muindasitiri yemachira, pamwe nekuchena kwesiriki, mvere dzemakwai, nayiloni nedzimwe machira. Sezvo sodium hydrosulfite isina simbi dzinorema, ruvara rwejira rakacheneswa runopenya zvikuru uye haruna kuomarara.

2. Sodium hydrosulfite inogona kushandiswawo pakuchenesa chikafu, zvakaita segelatin, sucrose, michero ine makeke, nezvimwewo, pamwe nesipo, mafuta emhuka (miti), bamboo, porcelain clay bleaching.

3. Mubasa rekugadzira zvinhu zvakasikwa, sodium hydrosulfite inoshandiswa senzira yekuderedza kana kuti bleaching mukugadzira madhayi nemishonga, kunyanya senzira yebleaching yekugadzira mapepa emapuranga emapuranga.

4. Sodium hydrosulfite inogona kuderedza maion akawanda esimbi dzakakora akadai sePb2+, Bi3+, nezvimwewo kuita simbi mukurapa mvura nekudzora kusvibiswa, uye inogonawo kushandiswa kuchengetedza chikafu nemichero.

Njodzi
Inobvira moto:Sodium dithionite chinhu chinobatidza moto chemhando yepamusoro kana chakanyorova zvichienderana nezvinodiwa nenyika. Chinoita zvine simba kana chasangana nemvura, chichiburitsa magasi anobatidza moto akadai sehydrogen sulfide nesulfur dioxide, uye chichiburitsa kupisa kwakawanda. Muedzo wekuita ndewekuti: 2Na2S2O4+2H2O+O2=4NaHSO3, uye zvigadzirwa zvinobatidzawo kugadzira hydrogen sulfide nesulfur dioxide. Sodium dithionite ine mamiriro epakati evalent yesarufa, uye hunhu hwayo hwemakemikari hahuna kugadzikana. Inoratidza hunhu hwakasimba hwekuderedza. Kana ikasangana neacids dzakasimba dzeoxidizing, dzakadai sesulfuric acid, perchloric acid, nitric acid, phosphoric acid nedzimwe acids dzakasimba, zviviri izvi zvichasangana neredox reaction, uye kuita kwacho kune simba, kuchiburitsa kupisa kwakawanda nezvinhu zvine chepfu. Muedzo wayo wekuita kwacho ndewekuti: 2Na2S2O4+4HCl=2H2S2O4+4NaCl

Kupisa kunoitika kamwe kamwe:Sodium dithionite ine poindi yekupisa inongoerekana yavapo ye250℃. Nekuda kwepoindi yayo yekupisa yakaderera, isimbi inobvira moto yemhando yepamusoro (poindi yekupisa inowanzo kuve pasi pe300℃, uye poindi yekupisa yakaderera iri pasi pe100℃). Zviri nyore kwazvo kutsva kana yaiswa pakupisa, moto, kukweshana uye kurova. Kumhanya kwekupisa kunokurumidza uye njodzi yemoto yakanyanya. Gasi rehydrogen sulfide rinogadzirwa panguva yekupisa rinogonawo kukonzera nzvimbo yakakura yekupisa, zvichiwedzera njodzi yemoto.

Kuputika:Sodium dithionite chinhu chine hupfu hweyero yakapfava. Chinhu chine hupfu chiri nyore kugadzira musanganiswa unoputika mumhepo. Kuputika kweguruva kunoitika kana wasangana nechinhu chinopisa. Musanganiswa we sodium dithionite nezvimwe zvinhu zvinopisa, zvakaita se chlorates, nitrates, perchlorates, kana permanganate, unoputika. Kunyangwe paine mvura, inoputika mushure mekukweshana kudiki kana kurovera, kunyanya mushure mekuora kwekupisa, gasi rinobvira rinogadzirwa mushure mekunge reaction yasvika pamuganho wekuputika, ipapo njodzi yaro yekuputika inokura.
