Inkqubo yoLungiselelo oluMiselweyo lwe-Oxalic Acid
Inkqubo yokulungiselela isisombululo kufuneka ilandele ngokungqongqo imigaqo yelebhu yeekhemikhali. Okokuqala, khetha izikhongozeli ezenziwe nge-polyethylene enoxinano oluphezulu (i-HDPE), enika ukumelana okuphezulu kwe-oxalic acid xa kuthelekiswa neeplastiki eziqhelekileyo. Izikhongozeli zeglasi zingasetyenziswa ixesha elifutshane, kodwa ukugcina ixesha elide kunokubangela ukuvuza kwe-sodium ion, okuchaphazela uzinzo lwesisombululo.
Xa ulungiselela, soloko ulinganisa ubungakanani bamanzi obufunekayo kuqala, uze ugalele kancinci i-oxalic acid ecaleni kwesikhongozeli. Olu landelelwano akufuneki lujikwe. Uvavanyo lubonisa ukuba ukongeza amanzi kwi-concentrated acid kubangela impendulo ye-exothermic ekhawulezileyo efikelela kuma-80–100°C, nto leyo enokubangela iingozi zokutshiza. Ukulandela ulandelelwano oluchanekileyo kugcina ubushushu bunyuka ngaphakathi komlinganiselo okhuselekileyo.
Ukuze uxube, sebenzisa iglasi okanye i-polytetrafluoroethylene (PTFE) stir bar, kwaye uxube rhoqo imizuzu emi-5-7 de isisombululo sicace ngokupheleleyo. Qaphela ukuba i-oxalic acid dissolving yinkqubo ye-endothermic. Vumela isisombululo esilungisiweyo ukuba sime imizuzu engama-20-30 ukuze sifikelele kubushushu begumbi, apho i-pH iya kuzinza kuluhlu olufanelekileyo lwe-1.5-2.0.
I-Oxalic Acid – Zibo Anhao Chemical Co., Ltd.
I-Zibo Anhao Chemical Co., Ltd. ngumvelisi othembekileyo nomthengisi we-oxalic acid ecocekileyo kakhulu (i-ethanedioic acid, i-CAS 144‑62‑7) enekomkhulu layo eZibo, eShandong, eTshayina. I-oxalic acid yethu ifumaneka kwiifom ze-anhydrous (C₂H₂O₄, MW 90.03) kunye ne-dihydrate (H₂C₂O₄·2H₂O, MW 126.07), enobumsulwa obuncinci be-99.6%. Ibonakala njengeekristale ezingenambala okanye umgubo omhlophe wekristale, ayinavumba, kwaye iyanyibilika kakhulu emanzini nakwi-ethanol.
Yenziwe phantsi kolawulo oluqinileyo lomgangatho kunye neenkqubo eziqinisekisiweyo ze-ISO 9001, i-oxalic acid yethu ihlangabezana nemigangatho yemizi-mveliso kunye ne-reagent kunye nokungcola okuphantsi (Cl⁻ ≤0.005%, SO₄²⁻ ≤0.10%, Fe ≤0.05%). Njenge-dicarboxylic acid eguquguqukayo kunye ne-reducing agent, isebenza njenge-agent ephambili ye-chelating, i-agent ye-bleaching, kunye ne-chemical intermediate. Isetyenziswa kakhulu kunyango lomphezulu wesinyithi (ukususa umhlwa, ukudlulisa), ukudaya kunye nokuprinta ilaphu (i-mordant, i-bleach), ukuthanjiswa kwesikhumba, ukupolishwa kwemabula, kunye nonyango lwamanzi. Ikwabalulekile ekukhutshweni kwezinto ezinqabileyo zomhlaba, ukwenziwa kwezinto eziphilayo (iityuwa ze-oxalate/ii-esters), ii-intermediate zamayeza, kunye neefomyula zemveliso yokucoca.
Apha e-Anhao Chemical, siqinisekisa ukuhanjiswa okuzinzileyo, ukuhlolwa komgangatho okungqongqo, kunye nokupakishwa okuguquguqukayo: iingxowa ezingama-25kg, iitanki ze-FIBC ezingama-500kg/1000kg, kunye ne-ISO. Ngamava eminyaka emininzi emveliso yeekhemikhali kunye nokuthumela kwamanye amazwe, sinikezela nge-oxalic acid kubathengi kulo lonke elaseMzantsi-mpuma Asia, eYurophu, eMbindi Mpuma, nakwezinye iindawo, sixhaswa yinkxaso yobuchwephesha kunye nothutho olusebenzayo. Sizimisele ukubonelela ngezisombululo ze-oxalic acid ezikumgangatho ophezulu nezingabizi kakhulu ezilungiselelwe iimfuno zakho zoshishino kunye norhwebo.
