Mokhoa oa ho Lokisetsa Oxalic Acid e Tloaelehileng
Mokhoa oa ho lokisa tharollo o tlameha ho latela ka tieo mekhoa ea laboratori ea lik'hemik'hale. Taba ea pele, khetha lijana tse entsoeng ka polyethylene e nang le bongata bo phahameng (HDPE), e fanang ka khanyetso e phahameng ea oxalic acid ha e bapisoa le polasetiki e tloaelehileng. Lijana tsa khalase li ka sebelisoa nako e khuts'oane, empa polokelo ea nako e telele e ka baka ho tsoa ha sodium ion, e amang botsitso ba tharollo.
Ha o ntse o lokisa, kamehla lekanya bongata ba metsi bo hlokahalang pele, ebe o tshela butle-butle o kenya oxalic acid ka lehlakoreng la setshelo. Tatellano ena ha ea lokela ho fetoloa. Liteko li bontša hore ho eketsa metsi ho concentrated acid ho baka karabelo ea hang-hang ea exothermic e fihlang ho 80–100°C, e leng se ka lebisang likotsing tsa ho fafatsa habonolo. Ho latela tatellano e nepahetseng ho boloka mocheso o phahama sebakeng se sireletsehileng.
Bakeng sa ho hlohlelletsa, sebelisa khalase kapa polytetrafluoroethylene (PTFE) stir bar, 'me u kopanye ka ho tsoelang pele metsotso e 5-7 ho fihlela tharollo e hlakile ka botlalo. Hlokomela hore ho qhibiliha ha oxalic acid ke ts'ebetso ea endothermic. Lumella tharollo e lokiselitsoeng ho ema metsotso e 20-30 ho fihlela tekanyo ea mocheso oa kamore, moo pH e tla tsitsa ka tekanyo e loketseng ea 1.5-2.0.
Asiti ea Oxalic – Zibo Anhao Chemical Co., Ltd.
Zibo Anhao Chemical Co., Ltd. ke moetsi le mofani ea tšepahalang oa oxalic acid e hloekileng haholo (ethanedioic acid, CAS 144‑62‑7) e nang le ntlo-kholo e Zibo, Shandong, Chaena. Oxalic acid ea rona e fumaneha ka mefuta ea anhydrous (C₂H₂O₄, MW 90.03) le dihydrate (H₂C₂O₄·2H₂O, MW 126.07), e nang le bohloeki bo bonyane ba 99.6%. E hlaha e le likristale tse bonaletsang tse se nang 'mala kapa phofo e tšoeu ea kristale, ha e na monko, 'me e qhibiliha haholo metsing le ethanol.
E hlahisitsoe tlas'a taolo e tiileng ea boleng le lits'ebetso tse netefalitsoeng tsa ISO 9001, asiti ea rona ea oxalic e fihlela maemo a indasteri le a reagent ka litšila tse tlase (Cl⁻ ≤0.005%, SO₄²⁻ ≤0.10%, Fe ≤0.05%). Jwalo ka asiti ea dicarboxylic le moemeli oa ho fokotsa lintho tse fapaneng, e sebetsa e le moemeli oa bohlokoa oa chelating, moemeli oa bleach, le moemeli oa lik'hemik'hale. E sebelisoa haholo kalafong ea bokaholimo ba tšepe (ho tlosa mafome, ho passivation), ho daea le ho hatisa masela (mordant, bleach), ho soeufatsa letlalo, ho bentša 'mabole le kalafo ea metsi. E boetse e bohlokoa bakeng sa ho ntša likarolo tse sa tloaelehang tsa lefats'e, tlhahiso ea organic (matsoai a oxalate/esters), metsoako ea meriana le mekhoa ea ho hloekisa lihlahisoa.
Ho Anhao Chemical, re netefatsa phepelo e tsitsitseng ea bongata, tlhahlobo e matla ea boleng, le sephutheloana se tenyetsehang: mekotla ea 25kg, litanka tsa 500kg/1000kg tsa FIBC, le ISO. Ka lilemo tse mashome tsa tlhahiso ea lik'hemik'hale le boiphihlelo ba ho romela kantle ho naha, re fana ka oxalic acid ho bareki ho pholletsa le Asia Boroa-bochabela, Europe, Bochabela bo Hare, le libakeng tse ling, re tšehelitsoe ke tšehetso ea botekgeniki ea litsebi le thepa e sebetsang hantle. Re ikemiselitse ho fana ka litharollo tsa oxalic acid tsa boleng bo holimo, tse theko e tlaase tse etselitsoeng litlhoko tsa hau tsa indasteri le tsa khoebo.
