Umukozi Ugabanya Ibiyobyabwenge (Rongalite)
Izina ry'ubutabire: Sodium hydrosulfite
Ugereranyije n’ibintu bigabanya ubushyuhe, Rongalite itera kwangirika guke cyane ku myenda. Ishobora gukoreshwa ku myenda ikozwe mu migozi itandukanye nta ngaruka mbi yangiza, niyo mpamvu izina "Rongalite" (bisobanura "ifu itekanye" mu Gishinwa). Sodium hydrosulfite ni igikoresho cy’umucanga wera cyangwa umuhondo woroshye gifite ubushyuhe bwa 300°C (gushonga) n’ubushyuhe bwa 250°C. Ntishongera muri ethanol ariko ishongera muri hydroxide ya sodium. Iyo igeze mu mazi, irakora cyane kandi igashya.
Igenzura ry’ubuziranenge bwa sodium hydrosulfite rirakomeye cyane, aho buri cyiciro gikorerwa igenzura ry’uruganda n’igenzura rya SGS ry’umwuga, kugira ngo ubwiza bushobore kwihanganira igihe. Kanda hano kugira ngo ubone ibiciro bigabanyirijwe ibiciro.
