He aha nga taonga me nga whakamahinga matua o te rongalite?
Ingoa: Sodium formaldehyde sulfoxylate;Rongalite C lumps;Rongalite dihydrate;
Konutai bisulfoxylate formaldehyde; konutai hydroxymethane sulfinate
tātai rāpoi:NaHSO2-CH2O-2H2O
CAS No.:149-44-0/6035-47-8
Āhuatanga: E mōhiotia ana ko te sodium formaldehyde bisulfate (rongalite).
Rongalite paura translucent tioata rhombohedral ma ranei mongamonga iti.
Ko te kiato ahua 1.80-1.85g/cm3. ira whakarewa 64 ℃ (kua memeha ki roto i te wai tioata). Ka pirau ki runga ake i te 120°C.
He memeha noa ki te wai, he paku whakarewa ki te waipiro.
He pai ake te tote anhydrous. Heoi, ka memeha haere i te hau makuku. He tino whakaheke i te pāmahana teitei.
Ko te tikanga tuku iho e toru-taahiraa mo te paura rongalite ko te paura zinc me te wai hei hanga slurry,
haere ki roto i te whanariki hauhā mo te tauhohenga ki te whakaputa i te zinc dithionite, katahi ka taapirihia te taapiri formaldehyde,
te whakaheke i te paura konutea, ka tauhohe ki te konutai waikawa hei whakaputa.
Ko te tikanga hanga kotahi-taahiraa hou e whakamahi ana i te konutai metabisulphite hei rauemi mata
a ka oti i tetahi taahiraa ma te whakaheke i te paura konutea me te taapiri o te formaldehyde.
Ka whakamahia hei kaihoko tuhi me te kaihoko whakaheke mo te ta me te tae,
mo te whakahiato rapa, mo te hanga huka,
mo te hanga waikano indigo me te waikano whakaheke.
Ko te konutai formaldehyde sulfoxylate i hokona e Rongda Chemical ka mahia ma te whakamahi i te tikanga hou.
Ma nga painga e whai ake nei:
ihirangi iti rawa o te konganuku taumaha
tuku ratonga pai muri-hoko
ingoa runga i runga i te mara matū
