Kushandiswa uye kugadzirwa kwe sodium formaldehyde sulfoxylate

Nguva: 2021-07-09 Hits: 226

Sodium sulfoxylate formaldehyde (NaHSO2 · CH2O · 2H2O),

Uyewo inozivikanwa assodium formaldehyde sulfoxylate,

Zita rezvinhu:Rongalite C.

Ibhuroko jena rinopenya rine nzvimbo yekunyungudika ye64 ℃. Iyo ine simba reducibility pakupisa kwakanyanya uye inogona kupera machira akadhayiwa.

Naizvozvo, inonyanya kushandiswa seanoburitsa muindasitiri yekudhinda uye yekudhaya, semugadziri we bleaching murubber synthesis uye shuga indasitiri.

Nekuvandudzwa uye kushandiswa kwezvigadzirwa, mumakore achangopfuura, yakashandiswawo muindasitiri yesipo uye kurapwa senge antidote yeHg, Bi, Ba.

Kugadzirwa kwerongalite kunowanzo shandisa nzira yechinyakare-nhanho nhatu, dzinoti zinc powder-sulfur dioxide-formaldehyde nzira.

Ndiko kuti, sulfur dioxide, zinc powder, uye formaldehyde inoshandiswa sezvinhu zvakasvibirira, uye sulfur dioxide uye zinc powder zvinogadzirisa kuumba zinc dithionite (ZnS2O4), uyezve formaldehyde kuwedzera, zinc powder kuderedza uye sodium hydroxide metathesis reaction kuti iite chigadzirwa.

Kugadzirwa kwedomerongalite kunoshandisawo mabasa echivanhu ataurwa pamusoro apa. Zvigadzirwa zvinonyanya kupihwa kumusika wepamba, uye zvimwe zvinotumirwa kuSoutheast Asia.

Zvatinosuma inzira itsva , ndiko kuti, nzira yekuwana chigadzirwa kubva kune sodium metabisulfite sechinhu chakasvibiswa kuburikidza nekuderedza zinc powder uye kuwedzerwa kwe formaldehyde mune imwe nhanho.

Zvinhu zvakasvibirira zvakaderedzwa uye zvinowedzerwa mu kettle imwe chete, uye zvose zvinogadziriswa zvinoshandurwa kuva zvigadzirwa, uye hapana tsvina.

Pamusoro pezvigadzirwa zvikuru, zvakare inogadzira kemikari yakachena zinc oxide (99.5%) zvigadzirwa.

Iyo nzira ine maitiro epfupi maitiro, yakagadzikana tekinoroji mamiriro, yakaderera michina yekudyara uye nyore kushanda.

Muchinyorwa chinotevera, ini ndichagovera maitiro ekugadzira ane chekuita nesodium formaldehyde sulfoxylate.

Joinha isu uye uve wekutanga kuziva nezve edu azvino zvigadzirwa uye kukurudzira.
