Xiaki xo hunguta (Rongalite) .
Vito ra Tikhemikhali: Sodium hydrosulfite
Loko ku pimanyisiwa na ti oxidizing agents, Rongalite yivanga ku onhaka kutsongo swinene eka malapi. Yinga tirhisiwa eka swiambalo leswi endliweke hi ti fibre to hambana hambana handle ko vanga khombo, hikokwalaho ka vito ra “Rongalite” (leswivulaka “safe powder” hi Xichayina). sodium hydrosulfite i crystalline yo basa ya sandi kumbe powder yo tshwuka yo vonikela ya ti khemikhali leyingana melting point ya 300°C (decomposition) na mahiselo ya ignition ya 250°C. A yi khuluki eka ethanol kambe yi khuluka eka sodium hydroxide solution. Loko yi hlangana ni mati, yi angula hi matimba naswona ya hisa.
Vulawuri bya hina bya khwalithi ya sodium hydrosulfite byi tiyile swinene, laha ntlawa wun’wana na wun’wana wu endlaka ku tikambela ka fektri na tioditi ta xiphurofexinali ta SGS, ku tiyisisa leswaku khwalithi yi nga tiyisela xikambelo xa nkarhi. Click laha ku kuma quote leyi hungutiweke.
