Kushandiswa
Oxalic acidMhinduro yakajairika imhinduro ye oxalic acid ine huwandu hwayo hwakarurama uye inoshandiswa zvakanyanya muminda yakaita sekuongorora makemikari, kugadzira maindasitiri, uye kutsvagisa kwesainzi. Nzira huru dzekushandisa ndeidzi:
Kuongorora kweMakemikari uye Kusarudza
- Kuganhurirwa kweAcid - Base: Oxalic acid iasidhi isina simba inogona kuita neutralization reaction ine mabhesi. Inogona kushandiswa se standard acid solution kuona huwandu hwe concentration alkaline solution isingazivikanwe. Semuenzaniso, kana uchiganhurirwa sodium hydroxide solution ne oxalic acid standard solution, uchishandisa phenolphthalein sechiratidzo, concentration chaiyo ye sodium hydroxide solution inogona kuverengerwa zvichibva pahukama hwe stoichiometric uye huwandu hwe oxalic acid standard solution inoshandiswa pakupera kwe titration.
- Redox Titration: Chinhu chekabhoni chiri muoxalic acid chine valence ye +3, zvichiratidza kudzikira uye kukwanisa kuita zvinhu zvine simba re oxidizing mu redox reaction. Munzvimbo ine acidic, sodium oxalate inogona kuoxidized ne potassium permanganate. Uchishandisa reaction iyi, oxalic acid standard solution inogona kushandiswa kugadzirisa huwandu hwakarurama hwe potassium permanganate solution.
Kudzora Hunhu hweMaindasitiri
- Kurapa Simbi Pamusoro: Mukugadzirisa pamusoro pesimbi dzakadai sealuminium, mhinduro dze oxalic acid dzinogona kushandiswa pakuchenesa nekucheka. Nekushandisa mhinduro ye oxalic acid standard, huwandu hwemhinduro hunogona kudzorwa nemazvo kuti ive nechokwadi chekuti simbi inogadzirisa simbi zvakanaka, nokudaro zvichivandudza mhando yechigadzirwa. Semuenzaniso, nekudzora huwandu hwemhinduro ye oxalic acid standard mukati mechikamu chakatarwa, chigadzirwa chearuminiyamu chinogona kuchekwa kuti chiwane chimiro chakafanana uye chakanaka pamusoro.
- Indasitiri yeElectroplating: Mhinduro ye oxalic acid inogona kushandiswa kugadzirisa acidity uye maumbirwo e electroplating solution, zvichiita kuti ive nechokwadi chekuti electroplated layer iri nani uye inoshanda zvakanaka. Kudzora mashandisirwo e oxalic acid zvakanaka kunobatsira kuvandudza kunamira, kupenya, uye kuramba ngura kwe electroplated layer, zvichiita kuti zvigadzirwa zve electroplated zvisvike pamhando yepamusoro.
Kurongedza uye Kutumira
25KG/Drum kana zvichienderana nezvinodiwa nevatengi.
Kutumira: Mhando nhanhatu dzezvinhu zvine njodzi uye zvinogona kutumirwa negungwa.
Chengeta uye chengeta
Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.
