Nthawi zambiri, kuchuluka kwa madzi osefukira kumatsegulidwa panthawi yopanga, ndipo valve yolowera imatsekedwa panthawi yomwe kupanga kuyimitsidwa.Siziyenera kukhetsa kapena kuwonjezera madzi mu thanki yonse.Ngati madzi akukhala mu thanki yoyamba yochapira pambuyo pa okosijeni kwa mphindi zingapo, kuthamanga kwa utoto kumathamanga, ndipo ngati madzi atakhala mu thanki yachiwiri yochapira, utotowo umachepetsedwa.
Popanga zinthu zachitsulo zokhala ndi utoto wonyezimira, njira yopaka utoto nthawi zambiri imatengedwa koyamba, kenako ndikubwereranso ku mbale yokhazikika. Chifukwa cha kusiyana kwamitundu yamitundu yotsatsira chitsulo chowongolera nthawi ndi yaying'ono (2 ~ 3 masekondi) , ndipo kugwiritsa ntchito lamulo lozimiririka kumatha kukhala ndi masekondi 10 ~ 15 a nthawi yowongolera mtundu, ndipo kufota kogwirizana kumathandizanso kumtundu womwewo wakumbuyo, chifukwa kutsanzira chitsulo kuzirala ndi mitundu yofananira ndi mtundu umakonda kutembenukira wobiriwira, ndipo utoto wanthawi imodzi umakonda kukhala wofiira.
Lembani zinthu zopachikidwa pa thanki yopaka utoto ndi thanki yoyamba yotsuka pambuyo poyanika mukamapachika musayime nthawi yopanda kanthu ndi yayitali kwambiri, apo ayi mawonekedwe amtundu adzawoneka riboni, mtundu wosagwirizana ndi kutha kwa chodabwitsa choyera, ayenera kukhala pang'ono pamtundu wa wotsatira wosambitsa mu nthawi, mtundu wolondola ayenera kukhala wachiwiri wosambitsa pambuyo.Nthawi zambiri, kutsanzira zitsulo zinthu, monga kusiyanitsa Chinsinsi mtundu wofiira, zimasonyeza kuti utoto nthawi sikokwanira kuti agwirizane mtundu; Ngati mtundu chikasu. , yakhala ndi utoto, malinga ndi kuya kwa mtundu, mutha kusankha kutsika mu thanki yopaka utoto kapena mu thanki yoyamba yochapira mutapaka utoto.
Njira yowonjezeramo mankhwala mu thanki yopaka utoto: stannous sulfate ndi nickel sulfate ziyenera kusungunuka mu thanki, ndipo chowonjezera cha utoto chiyenera kusungunuka m'madzi oyera (madzi oyera amasungunuka).Ndikoyenera kudziwa kuti chowonjezera cholimba chimatha kutsanuliridwa pambuyo pa kusungunuka kwathunthu, ndipo sulfuric acid yokhazikika imatha kutsanuliridwa mu thanki yopaka utoto.
Kutentha, nthawi ndi khalidwe la madzi la kutsuka madzi otentha pamaso pa electrophoresis ayenera kutsimikiziridwa.Ngati otsalira SO42- mu dzenje filimu okusayidi sanatsukidwe, chikasu ndi opacity wa utoto filimu zikhoza kuchitika pambuyo electrophoresis ndi baking.Muzikhalidwe bwinobwino, kutentha madzi otentha amalamulidwa pa 60 ~ 70 ℃, ndi kutsuka madzi otentha. nthawi ndi 5-10 mphindi.
