Chii chinonzi Sodium Dithionite?
Sodium dithionite (sodium hydrosulphite) chinhu chine simba rekuderedza kuchena kwevhu uye munyu unoderedza kuchena kwevhu unoshandiswa zvakanyanya mumaindasitiri uko mableach e oxidative akadai sehydrogen peroxide kana chlorine angakuvadza substrate kana kukonzera mhedzisiro isingadiwe. Inonyanya kukosha muindasitiri yemachira pakuderedza kucheneswa nekudhayiwa kwevat, uye muindasitiri yemapepa ne pulp pakuchenesa pulp yemakanika.
Kuchenesa Machira uye Maindasitiri
Mukugadzira dhayi yemuchina wekuchenesa, sodium dithionite ndiyo nzira inobvisa ruvara rweganda rusina kunyungudika kuita leucoform inonyungudika, zvichiita kuti ikwanise kunyungudika mu cellulosic fibers. Mushure mekudhayira, leucoform inodzoserwa mumhepo kuti igadzirezve pigment isinganyungudike inogara iri mufiber. Pakuchenesa, sodium dithionite inobvisa ruvara kubva mufibers dzechisikigo (mvere, sirika) uye tannin stains kubva pamatanda nepepa pasina kukuvara kwefiber kunokonzerwa neoxidative bleaches.
Kubata uye Kugovera
Sodium dithionite inonzwa hunyoro uye inopindirana nemvura zvakanyanya, ichiburitsa gasi resulfur dioxide; inofanira kuchengetwa mumidziyo yakavharwa munzvimbo inotonhorera, yakaoma kure nenzvimbo dzinopisa. Terracore Chemicals inopa sodium dithionite yemhando yepamusoro (85–88%) mumabhegi e25 kg nemadhiramu ekugadzira machira, magayo emapepa, mafekitori ekugadzira zvicherwa, uye vagadziri vezvigadzirwa zvekuchenesa zvemhando yepamusoro.
Applications
- Kuderedza dhayi yepurasitiki yemucheka uye kubvisa dhayi
- Kupenya kwesimbi yemuchina nepepa rakaraswa
- Kuvandudzwa kwechiedza cheKaolin nevhu remineral
- Kubvisa mavanga esimbi mukuwacha mbatya uye kuchenesa machira
- Kuchenesa chikafu neshuga
- Mushonga wekuderedza makemikari mukugadzirwa kwemakemikari muindasitiri
