He aha nā waiwai a me nā hoʻohana nui o rongalite?

Inoa: Sodium formaldehyde sulfoxylate; Rongalite C lumps; Rongalite dihydrate;

Sodium bisulfoxylate formaldehyde; sodium hydroxymethane sulfinate

Huina mole:NaHSO2-CH2O-2H2O

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

Nā waiwai: ʻike pū ʻia ʻo ka sodium formaldehyde bisulfate (rongalite).

Rongalite pauka translucent keʻokeʻo rhombohedral kristal a i ʻole nā ​​ʻāpana liʻiliʻi.

ʻIke ʻia ka mānoanoa 1.80-1.85g/cm3. ka helu heheʻe 64 ℃ (hoʻoheheʻe ʻia i loko o kona wai aniani). Decomposes ma luna o 120°C.

Hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka waiʻona.

ʻOi aku ka paʻa o ka paʻakai anhydrous. Akā naʻe, hoʻoheheʻe mālie ia i ka ea haʻahaʻa. Hoʻemi ikaika i nā wela kiʻekiʻe.

ʻO ke ʻano hana kuʻuna ʻekolu-ʻanuʻu no ka pauka rongalite ka pauka zinc a me ka wai e hana ai i kahi slurry,

e komo i loko o ka sulfur dioxide no ka hana ʻana i ka zinc dithionite, a laila hoʻohui i ka formaldehyde hoʻohui,

ka hoʻemi ʻana i ka pauka zinc a laila hoʻopili me ka sodium hydroxide e hana ai.

Hoʻohana ʻia ke ʻano hana hana hou hoʻokahi i ka sodium metabisulphite ma ke ʻano he kumu

a ua hoʻopau ʻia i hoʻokahi ʻanuʻu ma ka hoʻemi ʻana i ka pauka zinc a me ka hoʻohui ʻana o formaldehyde.

Hoʻohana ʻia ʻo ia ma ke ʻano he mea pena kiʻi a me ka mea hoʻohaʻahaʻa no ka paʻi ʻana a me ke kala ʻana,

no ka hana ʻana i ke kopa, no ka hana ʻana i ke kō,

no ka hana ʻana i nā wai waihoʻoluʻu indigo a me ka hoʻohaʻahaʻa i nā wai.

Hana ʻia ka sodium formaldehyde sulfoxylate i kūʻai ʻia e Rongda Chemical me ka hoʻohana ʻana i ke kaʻina hana hou.

Me keia mau pomaikai:

haʻahaʻa loa o ka metala kaumaha

hāʻawi maikaʻi loa ma hope o ke kūʻai aku

kūlana kiʻekiʻe ma ke kahua kemika
