Mafunso Ofunsidwa Kawirikawiri

Mukufuna thandizo? Onetsetsani kuti mwapita ku malo athu othandizira kuti mupeze mayankho a mafunso anu!

Kodi tingasindikize chizindikiro chathu pa chinthucho?

Inde, tikhoza kuchita. Ingotitumizirani kapangidwe ka logo yanu.

Kodi mumalandira maoda ang'onoang'ono?

Inde. Ngati ndinu wogulitsa pang'ono kapena bizinesi yoyambira, ndife okonzeka kukula nanu. Ndipo tikuyembekezera kugwira nanu ntchito limodzi kwa nthawi yayitali.

Nanga mtengo wake ndi wotani? Kodi mungaupange kukhala wotsika mtengo?

Nthawi zonse timaona ubwino wa kasitomala kukhala chinthu chofunika kwambiri. Mtengo ungathe kukambidwa pazifukwa zosiyanasiyana, tikukutsimikizirani kuti mupeza mtengo wopikisana kwambiri.

Kodi mumapereka zitsanzo zaulere?

Ndife okondwa kuti mutha kutilembera ndemanga zabwino ngati mumakonda zinthu ndi ntchito zathu, tidzakupatsani zitsanzo zaulere pa oda yanu yotsatira.

Kodi mumatha kupereka zinthu pa nthawi yake?

Zachidziwikire! Takhala akatswiri pa mzerewu kwa zaka zambiri, makasitomala ambiri amapanga mgwirizano ndi ine chifukwa timatha kutumiza katunduyo pa nthawi yake ndikusunga katunduyo ali wabwino kwambiri!

Kodi ndingapite ku kampani yanu ndi fakitale yanu ku China?

(1) Kuchotsa Madontho a Dzimbiri pa Nsalu
Chitsulo chomwe chimakhudzidwa ndi mpweya ndi chinyezi cha mumlengalenga chimapanga zinthu zovuta zomwe zimatchedwa dzimbiri. Ngakhale kuti dzimbiri limasiyanasiyana malinga ndi momwe zimakhalira, dzimbiri lonse limakhala ndi ma ayoni atatu achitsulo (Fe3+). Madontho a dzimbiri pa nsalu za thonje amapanga zilema zosaoneka bwino zomwe ziyenera kuchotsedwa, ndipo oxalic acid ndi chinthu chothandiza kwambiri pa izi.
Njira: Oxalic acid imayanjana ndi ma ayoni achitsulo atatu (Fe3+) kuti ipange complex ya anionic yosungunuka
[Fe(C2o4)3−, yomwe imasungunuka m'madzi, zomwe zimapangitsa kuti dzimbiri lisambitsidwe.
Fomula Yovomerezeka: 20 g/L oxalic acid + ~30 mL/L 98% acetic acid.
Chenjezo Lofunika Kwambiri: Oxalic acid imatha kuwononga ulusi. Pambuyo pochiza, nsalu za thonje ziyenera kutsukidwa bwino kuti zichotse oxalic acid yotsala. Ngati sizitsukidwa bwino, yankho la oxalic acid lochepetsedwa lidzakhazikika kwambiri pakuwumitsa nsalu, kuwononga ulusi kwambiri komanso kuyambitsa mabowo. Chenjezoli likugwiranso ntchito ku nsalu za nayiloni, komwe oxalic acid imagwiritsidwa ntchito kuchotsa madontho a dzimbiri omwe amachititsa chikasu.
