Cov Txheej Txheem Npaj Txheem Oxalic Acid
Cov txheej txheem npaj cov tshuaj yuav tsum ua raws li cov txheej txheem kuaj tshuaj lom neeg. Ua ntej, xaiv cov thawv ua los ntawm cov polyethylene siab (HDPE), uas muaj kev tiv taus oxalic acid zoo dua li cov yas ib txwm. Cov thawv iav siv tau rau lub sijhawm luv luv, tab sis kev khaws cia ntev tuaj yeem ua rau sodium ion leaching, cuam tshuam rau kev ruaj khov ntawm cov tshuaj.
Thaum npaj, ib txwm ntsuas qhov ntau ntawm cov dej uas xav tau ua ntej, tom qab ntawd maj mam nchuav cov oxalic acid rau hauv qab ntawm lub thawv. Qhov kev txiav txim no yuav tsum tsis txhob thim rov qab. Kev sim qhia tau tias kev ntxiv dej rau hauv cov kua qaub concentrated ua rau muaj kev hloov pauv exothermic tam sim ntawd mus txog 80-100°C, uas tuaj yeem ua rau muaj kev sib tsoo dej. Ua raws li qhov kev txiav txim kom raug yuav ua rau qhov kub nce siab nyob rau hauv qhov kev nyab xeeb.
Rau kev sib tov, siv lub khob iav lossis polytetrafluoroethylene (PTFE) sib tov, thiab sib tov tas li rau 5-7 feeb kom txog thaum cov tshuaj ntshiab tag nrho. Nco ntsoov tias kev yaj ntawm oxalic acid yog ib qho txheej txheem endothermic. Cia cov tshuaj uas tau npaj tseg sawv rau 20-30 feeb kom mus txog qhov sib npaug ntawm qhov kub thiab txias hauv chav tsev, thaum lub sijhawm ntawd pH yuav ruaj khov hauv qhov ntau ntawm 1.5-2.0.
Oxalic Acid - Zibo Anhao Chemical Co., Ltd.
Zibo Anhao Chemical Co., Ltd. yog ib lub tuam txhab tsim khoom thiab muag khoom uas ntseeg siab tau ntawm cov kua qaub oxalic acid (ethanedioic acid, CAS 144‑62‑7) uas muaj lub hauv paus nyob hauv Zibo, Shandong, Suav teb. Peb cov kua qaub oxalic acid muaj ob hom: anhydrous (C₂H₂O₄, MW 90.03) thiab dihydrate (H₂C₂O₄·2H₂O, MW 126.07), uas muaj qhov huv tsawg kawg nkaus 99.6%. Nws zoo li cov siv lead ua pob tshab tsis muaj xim lossis hmoov dawb crystalline, tsis muaj ntxhiab, thiab yaj tau zoo hauv dej thiab ethanol.
Tsim los ntawm kev tswj xyuas zoo thiab ISO 9001-certified processes, peb cov oxalic acid ua tau raws li cov qauv kev lag luam thiab reagent-qib nrog cov khoom tsis huv tsawg (Cl⁻ ≤0.005%, SO₄²⁻ ≤0.10%, Fe ≤0.05%). Raws li cov dicarboxylic acid thiab cov neeg sawv cev txo qis, nws ua haujlwm ua tus neeg sawv cev chelating tseem ceeb, tus neeg sawv cev bleaching, thiab tshuaj lom neeg nruab nrab. Siv dav hauv kev kho qhov chaw hlau (tshem tawm xeb, passivation), textile dyeing & printing (mordant, bleach), tawv tanning, marble polishing, thiab kev kho dej. Nws tseem ceeb heev rau kev rho tawm cov khoom tsis tshua muaj, organic synthesis (oxalate ntsev / esters), tshuaj nruab nrab, thiab cov tshuaj ntxuav cov tshuaj.
Ntawm Anhao Chemical, peb ua kom muaj kev ruaj khov ntawm cov khoom loj, kev tshuaj xyuas zoo, thiab kev ntim khoom yooj ywm: 25kg hnab, 500kg/1000kg FIBC, thiab ISO tanks. Nrog ntau xyoo ntawm kev tsim tshuaj lom neeg thiab kev xa tawm, peb xa oxalic acid rau cov neeg siv khoom thoob plaws Southeast Asia, Tebchaws Europe, Middle East, thiab dhau mus, txhawb nqa los ntawm kev txhawb nqa kev tshaj lij thiab kev xa khoom zoo. Peb cog lus tias yuav muab cov kev daws teeb meem oxalic acid zoo, pheej yig rau koj cov kev xav tau kev lag luam thiab kev lag luam.
