Kagwiritsidwe Ntchito
Oxalic acidNjira yokhazikika ndi yankho la oxalic acid lomwe lili ndi kuchuluka kodziwika bwino ndipo limagwiritsidwa ntchito kwambiri m'magawo monga kusanthula mankhwala, kupanga mafakitale, ndi kafukufuku wasayansi. Njira zazikulu zogwiritsira ntchito ndi izi:
Kusanthula kwa Mankhwala ndi Kutsimikiza
- Kuchuluka kwa asidi: Oxalic acid ndi asidi wofooka wa dibasic yemwe amatha kuchitapo kanthu ndi ma base. Itha kugwiritsidwa ntchito ngati njira yokhazikika ya asidi kuti adziwe kuchuluka kwa yankho losadziwika la alkaline. Mwachitsanzo, poyesa yankho la sodium hydroxide ndi yankho lokhazikika la oxalic acid, pogwiritsa ntchito phenolphthalein ngati chizindikiro, kuchuluka kolondola kwa yankho la sodium hydroxide kumatha kuwerengedwa kutengera ubale wa stoichiometric ndi kuchuluka kwa yankho lokhazikika la oxalic acid lomwe limagwiritsidwa ntchito kumapeto kwa titration.
- Kuchuluka kwa mpweya mu oxalic acid: Katundu wa kaboni mu oxalic acid ali ndi valence ya +3, kusonyeza kuchepetsedwa mphamvu komanso kutha kuchitapo kanthu ndi zinthu zamphamvu zopangitsa kuti oxygen ikhale yofanana ndi redox. Mu acidity medium, sodium oxalate imatha kusungunuka ndi potassium permanganate. Pogwiritsa ntchito izi, njira yokhazikika ya oxalic acid ingagwiritsidwe ntchito kuyeretsa kuchuluka kolondola kwa potassium permanganate.
Kuwongolera Ubwino wa Mafakitale
- Kukonza Zinthu Pamwamba pa Chitsulo: Pakukonza zinthu pamwamba pa zitsulo monga aluminiyamu, njira zothetsera zinthu za oxalic acid zitha kugwiritsidwa ntchito pokonza ndi kuyeretsa. Pogwiritsa ntchito njira yokhazikika ya oxalic acid, kuchuluka kwa mankhwala kumatha kuyendetsedwa bwino kuti zitsimikizire kuti mphamvu ya pamwamba pa zitsulo ndi yokhazikika, motero kukonza ubwino wa mankhwala. Mwachitsanzo, powongolera kuchuluka kwa mankhwala a oxalic acid mkati mwa mtundu winawake, chinthu cha aluminiyamu chikhoza kujambulidwa kuti chikhale ndi mawonekedwe ofanana komanso okongola.
- Makampani Opangira Ma Electroplating: Njira yodziwika bwino ya oxalic acid ingagwiritsidwe ntchito kusintha acidity ndi kapangidwe ka yankho la electroplating, kuonetsetsa kuti layer yopangidwa ndi electroplated ndi yabwino komanso ikugwira ntchito bwino. Kuwongolera molondola kuchuluka kwa oxalic acid kumathandiza kukonza kukanikiza, kunyezimira, komanso kukana dzimbiri kwa layer yopangidwa ndi electroplated, kuonetsetsa kuti zinthu zomwe zapangidwa ndi electroplated zikukwaniritsa miyezo yaubwino.
Kulongedza ndi Kutumiza
25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Kutumiza: Mitundu 6 ya katundu woopsa ndipo imatha kutumizidwa kudzera panyanja.
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
