Ukusetyenziswa kwe-Oxalic Acid kwiPrinting and Dayeing Textile
Kwishishini leekhemikhali, i-oxalic acid isetyenziselwa ukuvelisa i-pentaerythritol, i-cobalt oxalate, i-nickel oxalate, i-basic fuchsin, izixhobo ze-reagent ezipheleleyo zohlalutyo lwentsimbi nomhlaba, ii-reagents zeekhemikhali, kunye nezinye iimveliso.
Kwiinkqubo zokudaya ngokukhawuleza, isebenza njengearhente yokuphuhlisa umbala kunye nokulinganisa.
Isebenza njengesixhobo sokunyibilikisa i-bleach kwimveliso yengca kunye nengqolowa (isebenzisa iipropati zokunciphisa i-oxalic acid) kwaye isusa amabala omhlwa (i-oxalic acid isabela kunye nentsimbi ukuze yenze i-soluble iron oxalate, ehlanjwa lula ngamanzi, ngaloo ndlela isusa amabala entsimbi kwimpahla).
Ukusetyenziswa kwe-Oxalic Acid kwiPrinting and Dayeing Textile
(1) Ukususa Amabala Okugqwala Kwilaphu
Xa intsimbi ivezwa yioksijini kunye nokufuma emoyeni, yenza i-compound eyinkimbinkimbi ebizwa ngokuba yi-rust. Nangona ukwakheka kwayo ngokuchanekileyo kuyahluka ngokweemeko zokwakheka, yonke i-rust ine-ioni ze-iron ezi-trivalent. Amabala e-rust kwimpahla yekotoni enza iziphene ezihlala zihleli ekufuneka zisuswe, kwaye i-oxalic acid sisixhobo esisebenzayo sokususa ezo ziphene. Umgaqo kukuba i-oxalic acid isabela kunye ne-ioni ze-iron ezi-trivalent (Fe³⁺) ukuze yenze i-ion e-soluble anionic complex, [Fe(C₂O₄)₃]³⁻, enyibilikiswa lula emanzini. Ukusetyenziswa okuqhelekileyo yi-20 g/L ye-oxalic acid ene-30 mL/L ye-98% acetic acid.
Inqaku Elibalulekileyo: I-oxalic acid ingonakalisa imicu. Emva konyango, amalaphu ekotoni kufuneka ahlanjwe kakuhle ngamanzi acocekileyo ukuze kususwe yonke intsalela ye-oxalic acid. Ukuba ayihlanjwanga kakuhle, i-diluted oxalic acid iya kuxinana ngexesha lokomiswa, nto leyo ebangela umonakalo omkhulu kwimicu kwaye idale imingxunya.
I-oxalic acid inokususa amabala okugqwala kwimpahla ye-nylon, ebeya kubangela ukuba kube tyheli.
(2) Ukususa igesi yeNitrous Acid ngexesha lokuphuhliswa ngedayi ye-Ingrain
Xa kusetyenziswa indlela ye-sodium nitrite yokuprinta ngokuthe ngqo ngeedayi ze-ingrain ecaleni kweedayi ze-naphthol, i-nitrous acid iveliswa ngexesha lokukhula kwe-sulfuric acid. Oku kubangela ukuba iityuwa ze-sodium ze-naphthol AS kwilaphu zenze iiprecipitates ezibomvu-mdaka, nto leyo ebangela ukuba kubekho i-ground emhlophe engalinganiyo. Ukususa i-nitrous acid, i-1–2 g/L ye-oxalic acid ngamanye amaxesha yongezwa kwisisombululo sokuphuhlisa i-sulfuric acid njenge-reducing agent (ethatha indawo ye-formic acid, i-urea, okanye i-sulfur). I-Oxalic acid inciphisa i-nitrous acid ibe yigesi ye-nitrogen, ithintela i-HNO₂ ukuba ingasabelani ne-AS ukuze yenze iikhompawundi ezimdaka.
I-Zibo Anhao Chemical Co., Ltd. ibonelela nge-Oxalic Acid (i-Ethanedioic Acid, i-CAS 144-62-7) ekumgangatho ophezulu eyenzelwe ukuthembeka kwimizi-mveliso kunye nokusebenza rhoqo. I-oxalic acid yethu ifumaneka njengomgubo omhlophe wekristale okanye iikristale ezicacileyo ezingenambala, ezinobunyulu obuyi-≥99.6%, ukufuma okuphantsi, kunye nokungcola okuncinci, okuqinisekisa iziphumo ezithembekileyo kuzo zonke izicelo.
Yenzelwe ukusetyenziswa ngeendlela ezahlukeneyo, igqwesile ekucoceni umphezulu wesinyithi, ukudaya kunye nokufunxa ilaphu, ukufunxa isikhumba, ukukhutshelwa komhlaba ongaqhelekanga, kunye nonyango lwamanzi amdaka. Ngenxa yeempawu ezinamandla zokunciphisa nokususa irhasi, isusa ngokufanelekileyo umhlwa, amaxolo, kunye namabala ngelixa ixhasa ukucutshungulwa kweekhemikhali ngokuchanekileyo.
Iveliswe phantsi kolawulo olungqongqo lomgangatho kwaye iqinisekiswe yi-SGS, i-BV, kunye ne-FAMI-QS, i-oxalic acid yethu ihlangabezana nemigangatho yemizi-mveliso yehlabathi. Sinikezela ngokupakisha okuguquguqukayo—iingxowa ezingama-25kg, iidrama ezingama-50kg, kunye nee-IBC ezinkulu—ngobonelelo oluzinzileyo kunye nothungelwano lobuchwephesha ukuxhasa ubudlelwane behlabathi.Nxibelelana nathi ukuze ufumane iiodolo ezininzi okanye iinkcukacha zobugcisa: info@anhaochemical.com
