Inqubo Yokulungiselela Ejwayelekile ye-Oxalic Acid
Inqubo yokulungiselela isixazululo kumele ilandele ngokuqinile izinqubo zamakhemikhali zezinga lelebhu. Okokuqala, khetha izitsha ezenziwe nge-polyethylene ephezulu (i-HDPE), enikeza ukumelana okuphezulu kwe-oxalic acid uma kuqhathaniswa nepulasitiki evamile. Izitsha zeglasi zingasetshenziswa isikhathi esifushane, kodwa ukugcina isikhathi eside kungabangela ukuvuza kwe-sodium ion, okuthinta ukuqina kwesisombululo.
Uma ulungiselela, hlala ulinganisa inani lamanzi elidingekayo kuqala, bese uthela kancane i-oxalic acid phansi ohlangothini lwesitsha. Lokhu kuhleleka akumelwe kuguqulwe. Ukuhlolwa kubonisa ukuthi ukwengeza amanzi ku-concentrated acid kubangela ukusabela okusheshayo kwe-exothermic okufinyelela ku-80–100°C, okungaholela kalula ezingozini zokuchaphaza. Ukulandela ukulandelana okufanele kugcina izinga lokushisa likhuphuka ngaphakathi kwebanga eliphephile.
Ukuze uxube, sebenzisa ingilazi noma i-polytetrafluoroethylene (PTFE) stir bar, bese uxuba njalo imizuzu emi-5-7 kuze kube yilapho ikhambi selicacile ngokuphelele. Qaphela ukuthi ukuncibilika kwe-oxalic acid kuyinqubo ye-endothermic. Vumela ikhambi elilungisiwe lime imizuzu engama-20-30 ukuze kufinyelelwe izinga lokushisa legumbi, lapho i-pH izozinza khona ebangeni elifanele lika-1.5-2.0.
I-Oxalic Acid – Zibo Anhao Chemical Co., Ltd.
I-Zibo Anhao Chemical Co., Ltd. ingumkhiqizi othembekile kanye nomhlinzeki we-oxalic acid emsulwa kakhulu (i-ethanedioic acid, i-CAS 144‑62‑7) enendlunkulu eZibo, eShandong, eShayina. I-oxalic acid yethu itholakala kokubili ngezinhlobo ze-anhydrous (C₂H₂O₄, MW 90.03) kanye ne-dihydrate (H₂C₂O₄·2H₂O, MW 126.07), enobumsulwa obuncane obungu-99.6%. Ibonakala njengamakristalu angenambala noma i-crystalline powder emhlophe, ayinaphunga, futhi incibilika kakhulu emanzini nase-ethanol.
Ikhiqizwe ngaphansi kokulawulwa kwekhwalithi okuqinile kanye nezinqubo eziqinisekiswe yi-ISO 9001, i-oxalic acid yethu ihlangabezana nezindinganiso zezimboni nezezinga le-reagent ezinokungcola okuphansi (Cl⁻ ≤0.005%, SO₄²⁻ ≤0.10%, Fe ≤0.05%). Njenge-dicarboxylic acid eguquguqukayo kanye ne-reducing agent, isebenza njenge-agent eyinhloko ye-chelating, i-bleaching agent, kanye ne-chemical intermediate. Isetshenziswa kabanzi ekwelapheni ubuso bensimbi (ukususa ukugqwala, ukudlulisa), ukudaya nokuphrinta izindwangu (i-mordant, i-bleach), ukushiswa kwesikhumba, ukupholisha imabula, kanye nokwelashwa kwamanzi. Ibalulekile futhi ekukhishweni kwezinto ezingavamile zomhlaba, ukwenziwa kwezinto eziphilayo (ama-oxalate salts/esters), izinto ezisetshenziswa emithini, kanye nokwakheka kwemikhiqizo yokuhlanza.
Kwa-Anhao Chemical, siqinisekisa ukutholakala kwenqwaba okuzinzile, ukuhlolwa kwekhwalithi okuqinile, kanye nokupakishwa okuguquguqukayo: izikhwama ezingama-25kg, amathangi angama-500kg/1000kg e-FIBC, kanye ne-ISO. Njengoba sineminyaka eminingi yokukhiqiza amakhemikhali kanye nesipiliyoni sokuthumela kwamanye amazwe, siletha i-oxalic acid kumakhasimende kulo lonke elaseNingizimu-mpumalanga ye-Asia, eYurophu, eMpumalanga Ephakathi, nangale kwalokho, sisekelwa ukwesekwa kobuchwepheshe obuchwepheshile kanye nokuphathwa kwempahla okusebenzayo. Sizibophezele ekuhlinzekeni ngezixazululo ze-oxalic acid ezisezingeni eliphezulu nezingabizi kakhulu ezilungiselelwe izidingo zakho zezimboni nezentengiselwano.
