Oxalic Acid: Mashandisirwo uye Chipimo
Oxalic acid imusanganiswa une acid yakawanda une chepfu, unonyanya kushandiswa mukuchenesa maindasitiri, kugadzira mishonga, kubvisa ngura munzvimbo dzakatarwa. Kubata ganda zvakananga kunogona kukonzera kutsva. Zvinosungirwa kupfeka mbatya dzekudzivirira, magirovhosi ekudzivirira uye magirazi ekudzivirira mukati menguva yese, uye kuchengetedza nzvimbo yekushanda ine mhepo yakanaka kudzivirira kuungana kweacid mhute munzvimbo dzakavharirwa. Pazasi pane tsananguro yekushandiswa uye dosage zvichibva pane zviitiko zvakasiyana, nekuchinja kunochinjika kune ratios uye mwero wekuderedzwa kwemvura mumaindasitiri.
Kubviswa kwengura yesimbi:Gadzirira mushonga une huwandu hwe8%–12% (mugumisiro wakawedzerwa munzvimbo ine alkaline inopisa zvakanyanya). Nyungudutsa 800 g kusvika 1.2 kg yeupfu hwe oxalic acid kana makristaro mu 10 kg yega yega yemvura yakachena. Pfapfaidza mushonga kaviri pamusoro pemidziyo mikuru yemakanika kana mapaipi kuti uwane mhedzisiro yakagadzikana, nenguva imwe chete yekuita kwemaminetsi angangoita gumi nemashanu. Mushure mekupukuta, sukurudza nemvura yakachena kusvika yanyatsomira kudzivirira acid yasara kubva mukuora kwezvinhu.
Kudhinda nekudhaya machira: Danho rekunyungudika rakakosha zvikuru. Kana paine kumanikidzwa kwakajairika uye tembiricha yepamusoro (80°C–100°C), shandisa 15 L ye oxalic acid solution (3% concentration) pa cubic meter yehuwandu hwemachira. Nyika jira mudhiramu kusvika mvura yapinda mufibers, wobva waisa kwemaminitsi 8–12. Tarisa kuchinja kweruvara uye kuchinja kwemachira panguva chaiyo.
Pakushandiswa kwemumba, chiyero chinofanira kuderedzwa zvakanyanya kudzivirira njodzi dzehutano:
Kuti uchenese mataira echimbuzi, shandisa mushonga unonyungudutsa une huwandu hwe1%–1.5%. Kazhinji, nyungudutsa 40–60 g yemabhuroko eoxalic acid mu2 L yemvura yakachena, woisiya pavara kweisingasviki maminetsi matatu, wozoikwesha nebhurashi rakasimba.
Kana paine ngura yakawanda pamataira epasi ane nzvimbo diki, isa mushonga we stock solution zvakananga kuti uvhare mavanga wosuka nemvura yakachena mukati memaminitsi mashanu.
Ziva kuti mushure mekuchenesa ne oxalic acid, jira rakaita sewakisi rinowanzo umbwa pamusoro petaira, zvichikonzera kusanyatsoona zvakanaka. Zvinokurudzirwa kupedzisa nekupolisha kwehunyanzvi kana mvura ine sipo isina kusimba kuti iite kuti iwedzere kunaka.

Oxalic Acid kubva kuZibo Anhao Chemical Co., Ltd.
Zibo Anhao Chemical Co., Ltd., yakavambwa muna 2015 uye iri muZibo, Shandong Province—nzvimbo huru yeindasitiri yemakemikari muChina—inopa uye inopa mishonga yemhando yepamusoro yemakemikari emumaindasitiri, ine oxalic acid seimwe yezvigadzirwa zvayo zvikuru. Oxalic acid yedu, inozivikanwawo se ethanedioic acid (CAS: 144-62-7 yeanhydrous, 6153-56-6 ye dihydrate), icrystalline solid chena ine kuchena kwakanyanya kusvika 99.5% min, inosangana nezvinodiwa zveindasitiri zvakasimba uye hunhu hwepasi rose.

Oxalic acid yedu, inozivikanwawo se ethanedioic acid (CAS: 144-62-7 yeanhydrous, 6153-56-6 ye dihydrate), icrystalline solid chena ine kuchena kwakanyanya kusvika 99.5% min, inosangana nezvinodiwa zveindasitiri zvakasimba uye hunhu hwepasi rose.
Inowanikwa mumhando dzeanhydrous nedihydrate, oxalic acid yedu ine hunhu hwakagadzikana hwemakemikari, inonyunguduka zvakanaka mumvura uye ethanol, uye inokwanisa kuderedza uye kuomesa simbi. Inoshandiswa zvakanyanya mukubvisa ngura, kuchena kwemachira, kutsvukisa dehwe, kugadzirisa rare earth, kugadzirisa mvura, uye kuongorora makemikari, zvichishanda sezvinhu zvakakosha mumaindasitiri akasiyana-siyana.
Tichitsigirwa nehurongwa hwakasimba hwekutengesa zvinhu uye masisitimu ekudzora mhando, tinovimbisa kuti zvigadzirwa zvedu zvinoenderana, nzira dzekurongedza dzinochinjika (mabhegi 25kg kana akagadziriswa), uye nzira dzakagadzikana dzekutumira zvinhu. Oxalic acid yedu yakatumirwa kunyika dzinopfuura makumi matatu nenzvimbo, kusanganisira Southeast Asia, Europe, America, neAfrica, zvichiwana mukurumbira nekuda kwehunhu hwayo hwepamusoro, mitengo inokwikwidzana, uye basa rehunyanzvi revatengi.
Tichitevedzera pfungwa ye "Quality First, Customer Supreme", Zibo Anhao Chemical Co., Ltd. yakazvipira kupa vatengi oxalic acid yepamusoro uye mhinduro dzemakemikari dzakazara. Isu tinotevedzera mitemo yekuchengetedza nekuchengetedza nharaunda, tichiona kugadzirwa kwezvinhu zvinogara kwenguva refu uye kuwanikwa kwezvinhu uku tichisangana nezvinodiwa nevatengi zvakasiyana-siyana pasi rese.
