Kushandiswa
Iyo oxal acidSolature Solution ndeye qualic acid mhinduro neyakavimbika yakasarudzika uye inoshandiswa zvakanyanya muminda yakadai sekuongororwa kwemakemikari, kugadzirwa kwemaindasitiri, uye kutsvakwa kwesainzi. Nzira huru yekushandisa ndeyekutevera:
Makemikari ekuongorora uye kutsunga
- Acid - Base titration: oxalic acid ndeye dibasic isina kusimba acid iyo inogona kuitwa neyakaitwa nezvibodzwa. Inogona kushandiswa seyakajairwa acid mhinduro yekuziva kusanzwisisika kwekusazivikanwa - kusimbisa alkaline solution. Semuenzaniso, pakatanga kuitisa sodium hydroxide solution ine oxolic acid solution, iyo yakasarudzika yeiyo sodioms, huwandu hwehupfumi hwechidhidhi uye huwandu hwechiratidzo
- Redox titration: Iyo carbon chinhu mu oxalic acid ine alisence ye +3, kuratidza kudzikisira uye kuve nekugona kuita neine simba rehupfumi zvinhu mune redox maitiro. Mune iyo acidium yepakati, sodium oxacolate inogona kuve oxidized ne potasium permananate. Uchishandisa iyi maitiro, iyo oxalic acid standard mhinduro inogona kushandiswa kuenzanisa iyo chaiyo yekusangana kweiyo potassiganate mhinduro mhinduro.
Maindasitiri Ekugona Kudzora
- Simbi Specreat kurapwa: Mumasangano ekurapa ekurapa esimbi senge aluminium, oxal acid mhinduro dzinogona kushandiswa kune iyo etching uye kuchenesa. Nekushandisa oxal acid yakajairwa mhinduro, iyo yekugadzirisa mhinduro inogona kudzorwa chaizvo kuti ive nechokwadi chekubatanidza uye kugadzikana kwesimbi yekurapa maitiro, saka kuvandudza chigadzirwa mhando. Semuenzaniso, nekudzora kusangana kweiyo oxalic acid solution mukati meimwe renji, chigadzirwa chealuminium chinogona kugumburwa kuti uwane yunifomu uye yakanaka nzvimbo yekuvhura.
- Electroplating Indasitiri: Iyo oxalic acid standard mhinduro inogona kushandiswa kugadzirisa iyo acidity uye kuumbwa kwemhinduro yeElectroplating Solution, ichisimbisa kunaka uye kuita kweiyo yemagetsi emagetsi. Kunyatso kudzora qualic acid kushamwaridzana kunobatsira kuvandudza kuderedza, kupokana kweiyo denderedzwa rewele, kunoita kuti zvigadzirwa zvemagetsi zvinosangana nemhando yemhando yepamusoro.
Kurongedza uye kutumira
25kg / chigubhu kana seyavo zvinodiwa nevatengi.
Kutumira: 6 mhando dzezvinhu zvine njodzi uye zvinogona kuendesa negungwa.
Chengetedza nekuchengetedza
HEREF Hupenyu: Mwedzi wemakumi maviri nemana kubva pazuva rekugadzira mukutanga kwekusarongeka kwekuchengetwa munzvimbo inotonhorera yakaoma yezuva, mvura.
Wantiallated Warehouse, kupisa kwakadzika kuoma, kuparadzaniswa kubva ku odifrilan, acids.
