Amfani
Oxalic acidMaganin da aka saba amfani da shi shine maganin oxalic acid wanda aka san shi da cikakken yawan aiki kuma ana amfani da shi sosai a fannoni kamar nazarin sinadarai, samar da masana'antu, da binciken kimiyya. Manyan hanyoyin amfani sune kamar haka:
Binciken Sinadarai da Tabbatarwa
- Tsarin Acid - Tushe: Oxalic acid wani acid ne mai rauni wanda zai iya fuskantar amsawar tsaka-tsaki tare da tushe. Ana iya amfani da shi azaman maganin acid na yau da kullun don tantance yawan maganin alkaline da ba a sani ba. Misali, lokacin da ake yin titration na maganin sodium hydroxide tare da maganin oxalic acid na yau da kullun, ta amfani da phenolphthalein a matsayin mai nuna alama, ana iya ƙididdige daidaiton yawan maganin sodium hydroxide bisa ga alaƙar stoichiometric da adadin maganin oxalic acid na yau da kullun da aka yi amfani da shi a ƙarshen titration.
- Redox Titration: Sinadarin carbon da ke cikin oxalic acid yana da ƙarfin +3, yana nuna raguwar amsawa da kuma iya amsawa da abubuwa masu ƙarfi na oxidizing a cikin redox reaction. A cikin matsakaici mai acidic, ana iya oxidize sodium oxalate ta hanyar potassium permanganate. Ta amfani da wannan amsawar, ana iya amfani da maganin oxalic acid na yau da kullun don daidaita daidaiton yawan maganin potassium permanganate.
Sarrafa Ingancin Masana'antu
- Maganin Saman Karfe: A cikin hanyoyin gyaran saman karafa kamar aluminum, ana iya amfani da maganin oxalic acid don gogewa da tsaftacewa. Ta hanyar amfani da maganin oxalic acid na yau da kullun, ana iya sarrafa yawan maganin daidai don tabbatar da daidaito da kwanciyar hankali na tasirin maganin saman karfe, don haka inganta ingancin samfur. Misali, ta hanyar sarrafa yawan maganin oxalic acid na yau da kullun a cikin takamaiman kewayon, ana iya yin zane da samfurin aluminum don samun yanayin saman iri ɗaya da kyau.
- Masana'antar Electroplating: Ana iya amfani da maganin oxalic acid na yau da kullun don daidaita acidity da abun da ke cikin maganin electroplating, yana tabbatar da inganci da aikin layin electroplating. Daidaita yawan sinadarin oxalic acid yana taimakawa wajen inganta mannewa, sheki, da juriyar tsatsa na layin electroplating, yana tabbatar da cewa samfuran electroplating sun cika ƙa'idodin inganci.
Marufi da Jigilar Kaya
25KG/Drum ko kuma kamar yadda ake buƙata daga abokin ciniki.
Jigilar kaya: nau'ikan kayayyaki masu haɗari guda 6 kuma ana iya isar da su ta teku.
Ajiyewa da adanawa
Rayuwar shiryayye: Watanni 24 daga ranar ƙera shi a cikin marufi na asali wanda ba a buɗe ba, an adana shi a wuri mai sanyi da bushewa, ba tare da hasken rana kai tsaye ba, ko ruwa.
Ma'ajiyar iska, Busar da ƙananan zafin jiki, An raba shi da sinadarai masu guba, acid.
