Ndezvipi zvinhu uye kushandiswa kukuru kwe rongalite?

Zita: Sodium formaldehyde sulfoxylate;Rongalite C mapundu;Rongalite dihydrate;

Sodium bisulfoxylate formaldehyde;sodium hydroxymethane sulfinate

Molecular formula:NaHSO2-CH2O-2H2O

CAS No.:149-44-0/6035-47-8

Zvivakwa:Inozivikanwawo sesodium formaldehyde bisulfate (rongalite).

Rongalite poda translucent chena rhombohedral makristasi kana zvidimbu zvidiki.

Inooneka density 1.80-1.85g/cm3. kunyungudika 64 ℃ (yakanyungudika mumvura yayo yekristaro). Inoora kupfuura 120°C.

Kunyungudika zvakasununguka mumvura, kunyungudika zvishoma mudoro.

Anhydrous salt yakanyanya kugadzikana. Zvisinei, inoora zvishoma nezvishoma mumhepo ine mwando. Kunyanya kuderedza pakupisa kwepamusoro.

Iyo yechinyakare-nhanho-nhanho yekugadzira nzira yerongalite poda ine zinc poda nemvura kuti igadzire slurry,

pfuura muSulfur dioxide kuti uite kuti ugadzire kunyange zinc dithionite, wobva wawedzera formaldehyde kuwedzera,

zinc poda kuderedza uye wobva waita ne sodium hydroxide kugadzira.

Iyo nyowani-imwe nhanho yekugadzira nzira inoshandisa sodium metabisulphite seyakagadzirwa zvinhu

uye inopedzwa mune imwe nhanho nekuderedzwa kwe zinc poda uye kuwedzerwa kwe formaldehyde.

Inoshandiswa semumiriri wekudhirowa uye inoderedza mumiriri wekudhinda nekudhaya,

yekugadzira rabha, yekugadzira shuga,

yekugadzira dhayi dze indigo uye kuderedza dhayi.

Iyo sodium formaldehyde sulfoxylate inotengeswa neRongda Chemical inogadzirwa uchishandisa maitiro matsva.

Uine zvinotevera zvakanakira.

yakaderera zviri mukati meheavy metal

ipa yakanakisa mushure mekutengesa sevhisi
