Kuti muthe kuchotsa dzimbiri, ndizofunika kudziwa zomwe zimapangidwira. Ngati maonekedwe a nkhaniyo sadziwika, kuchokera pakhoma kapena msoko wa zovala zoonongeka, dulani chidutswa chaching'ono ndikuchiyang'ana. Pachimake ichi, mukhoza kupanga dzimbiri lomwelo kuti muwone zomwe zimachititsa kuchotsedwa. Kuphunzira koteroko kudzakhala kofunikira makamaka ngati zojambulazo zasinthidwa. Ngati utoto umakhala wosasunthika kuchitapo kanthu kwa ma reagents ogwiritsidwa ntchito, atachotsa banga, zizindikiro zimakhalapo, zomwe zimakhala zoipitsitsa poyerekeza ndi dzimbiri zokha.
Kuti achotse zida za dzimbiri zopangidwa pa nsalu, madzi amachotsa mabala amadzimadzi amapangidwa, omwe amakhala ndi acetic ndi oxalic acid. Kugwira ntchito ndi ndalamazo ndizofunika kokha mu magalavu a mphira, kuchotsa utoto ayenera kugwiritsidwa ntchito ndi swaboni ya thonje, mutachotsa tsaya lakuthwa, minofu imatsukidwa ndi madzi ofunda.
Tsopano tikupereka kuti tiganizire momwe tingatulutsire madontho kuchokera ku dzimbiri, ngati palibe kukonzekera kwina.
Mankhwala a mandimu mwatsopano
Osakanizidwa ndi madzi a mandimu, dera lowonongeka liyenera kusungidwa ndi chitsulo chowotcha, kenaka pukutirani ndi swaboni ya thonje yotsekemera mu madzi a mandimu ndikutsuka dzikolo ndi madzi ofunda.
Acetic, oxalic acid
Supuni ya tiyi imodzi ya iliyonse ya zidulozi kuti muchepetse mu kapu yamadzi ndi kutentha pafupi ndi chithupsa. Nsalu yokhala ndi tsache imathamangira mwamsanga ndipo imatsukidwa bwino ndi madzi ndi kuwonjezera soda kapena ammonia. Ngati dzimbiri banga silichotsedwa nthawi yoyamba, bwerezani ndondomekoyi kangapo.
Hydrochloric acid
Zida zomwe zimakhala ndi thotho zonyansa zimatha kugwiritsidwa ntchito mu njira ya 2% ya hydrochloric acid ndipo imagwiritsidwa ntchito mpaka utoto utatha. Kenaka nkhaniyo iyenera kutsukidwa bwino, kuonjezera ammonia m'madzi (1 lita imodzi ya madzi - supuni 3 ammonia).
Oxalic acid ndi potassium carbonate
Kutentha utsi kumatha kuchotsedwanso ndi yankho la oxalic acid (supuni 2) ndi potaziyamu carbonate (supuni imodzi) pa galasi la madzi. Pofuna kukonzekera kusakaniza, asidi ndi potassium carbonate ziyenera kusungunuka padera, chophatikiza chilichonse mu 100 ml ya madzi, ndiyeno kusakaniza zotsatirazo. M'malo mwa potaziyamu carbonate, soda (sodium carbonate) ndi abwino, koma mumayenera kutenga madzi ambiri kukonzekera yankho ndipo zotsatira za kuchotsa utsi sizikhala zogwira mtima. Mbali yowonongeka ya minofu imathandizidwa ndi swab ya thonje, kenako minofu iyenera kuchapidwa.
Lemon
Mukhoza kuchotsa utoto wa dzimbiri ndi chidutswa cha mandimu, atakulungidwa mu gauze. Iyenera kuikidwa pa malo ogwira ntchito ndikugwedezeka ndi chitsulo chotentha. Ngati nsalu yowonongeka ili yoyera, ndiye mutatha kuchizira, utoto uyenera kukhala wothira ndi haidrojeni peroxide kapena kuupaka munthu wouma. Pambuyo pa mphindi 5-10, minofu ikhoza kutsukidwa.
Tartaric asidi ndi mchere wamchere
Pochotsa utoto, m'pofunikira kukonzekera chisakanizo cha tartaric asidi ndi mchere wothira (1: 1), kusakaniza ndi madzi, kukonzekeretsa slurry kuti agwiritse ntchito utoto wambiri. Kenaka nsaluyo imalimbikitsidwa kuti ikhedwe pa chinthu chilichonse ndikuyikidwa padzuwa mpaka malowa atatha. Kenaka, mankhwalawo ayenera kutsukidwa m'madzi ozizira, atatsuka m'madzi ofunda, pogwiritsa ntchito sopo ndikutsuka bwino.
Hyposulfite
Pofuna kuthetsa yankho lanu, tengani magalamu 15 a hyposulfite pa galasi la madzi, kusakanikirana, kutentha mpaka kutentha kwa 65 ° C. Potsatira njirayi, muyenera kutsikanso nsalu yotchinga, ikani iyo mpaka utoto utatha, ndiye mutsuke poyamba kutentha, ndiye - ndi madzi ozizira.
Mmene mungachotsere dzimbiri kuchokera ku nsalu zachikuda
Njira zogwiritsidwa ntchito pamwambazi zimachokera ku nsalu zoyera ndipo sizikugwiritsidwa ntchito pazinthu zamitundu. Nsalu yotayira ikhoza kuchotsedwa ndi sopo, glycerin ndi madzi (1: 1: 1). Zokonzekera zowonongeka ziyenera kuzungulidwa pa malo ochiritsidwa, ndipo patapita tsiku mankhwalawa ayenera kuchapa ndi kuchapidwa.
