Maitiro Ekugadzirira Oxalic Acid Yakajairika
Maitiro ekugadzirira mhinduro anofanira kunyatsotevedzera maitiro emurabhoritari emakemikari. Kutanga, sarudza midziyo yakagadzirwa nepolyethylene ine density yakakura (HDPE), iyo inopa simba rekudzivirira oxalic acid zvakanyanya kana tichienzanisa nemapurasitiki akajairwa. Midziyo yegirazi inogona kushandiswa kwenguva pfupi, asi kuchengetwa kwenguva refu kunogona kukonzera leaching ye sodium ion, zvichikanganisa kugadzikana kwemhinduro.
Paunenge uchigadzirira, tanga wayera huwandu hwemvura hunodiwa, wobva wadurura zvishoma nezvishoma oxalic acid pasi pechirongo. Kurongeka uku hakufanirwe kuchinjwa. Ongororo dzinoratidza kuti kuwedzera mvura mu concentrated acid kunokonzera exothermic reaction instantly inosvika 80–100°C, izvo zvinogona kukonzera tsaona dzemvura. Kutevedzera kurongeka kwakarurama kunoita kuti tembiricha ikwire munzvimbo dzakachengeteka.
Pakukurunga, shandisa girazi kana polytetrafluoroethylene (PTFE) stir bar, uye sanganisa nguva dzose kwemaminitsi 5-7 kusvika mhinduro yacho yanyatsojeka. Cherechedza kuti oxalic acid dissolving inzira ye endothermic. Rega mhinduro yakagadzirirwa imire kwemaminitsi 20-30 kuti isvike patembiricha yemukamuri, panguva iyo pH ichagadzikana munzvimbo yakakodzera ye1.5-2.0.
Oxalic Acid – Zibo Anhao Chemical Co., Ltd.
Zibo Anhao Chemical Co., Ltd. ikambani inovimbwa nayo uye inopa oxalic acid (ethanedioic acid, CAS 144‑62‑7) ine muzinda wayo muZibo, Shandong, China. Oxalic acid yedu inowanikwa mumhando dze anhydrous (C₂H₂O₄, MW 90.03) uye dihydrate (H₂C₂O₄·2H₂O, MW 126.07), ine kuchena kwe99.6%. Inoratidzika semakristaro asina ruvara kana upfu hwe crystalline chena, haina hwema, uye inonyunguduka zvakanyanya mumvura uye mune ethanol.
Yakagadzirwa pasi pekudzora kwakasimba kwehunhu uye maitiro akabvumidzwa neISO 9001, oxalic acid yedu inosangana nezvinodiwa zveindasitiri uye reagent-grade ine tsvina shoma (Cl⁻ ≤0.005%, SO₄²⁻ ≤0.10%, Fe ≤0.05%). Semushonga unoshanda zvakasiyana-siyana we dicarboxylic acid uye reduction agent, inoshanda semushonga unokosha we chelating, bleaching agent, uye chemical intermediate. Inoshandiswa zvakanyanya mukurapa simbi pamusoro pevhu (kubvisa ngura, passivation), dyeing & printing yemachira (mordant, bleach), dehwe reganda, marble polishing, uye kurapa mvura. Zvakakoshawo pakuburitsa zvinhu zvisingawanzoitiki zvevhu, organic synthesis (oxalate salts/esters), pharmaceutical intermediates, uye cleansing product formulations.
KuAnhao Chemical, tinovimbisa kuti zvinhu zvakawanda zvinogadzirwa zvakanaka, kuongorora kwakasimba kwemhando, uye kurongedza kunochinjika: mabhegi e25kg, 500kg/1000kg FIBC, uye matangi eISO. Nemakore akawanda eruzivo rwekugadzira makemikari nekutumira kunze kwenyika, tinoendesa oxalic acid kuvatengi kuSoutheast Asia, Europe, Middle East, nedzimwe nzvimbo, tichitsigirwa nerutsigiro rwehunyanzvi uye logistics inoshanda zvakanaka. Takazvipira kupa mhinduro dze oxalic acid dzemhando yepamusoro uye dzinoshanda dzakagadzirirwa zvinodiwa nemaindasitiri nemabhizinesi.
