Cov Ntsiab Cai Tseem Ceeb rau Kev Siv Oxalic Acid Solutions
Cov khoom siv tshuaj ntawm oxalic acid (ethanedioic acid) xav tau kev tswj hwm qhov sib piv ntawm cov tshuaj dilution. Cov tshuaj oxalic acid lag luam feem ntau muaj ob hom: hmoov crystalline thiab cov tshuaj uas tau npaj ua ntej. Hmoov crystalline muaj qhov huv siab (feem ntau ≥99%) thiab yuav tsum tau npaj los ntawm kos, thaum 30% -50% cov tshuaj sib xyaw ua ntej xav tau kev dilution thib ob.
Rau cov hmoov crystalline oxalic acid, qhov piv txwv kev nyab xeeb yog 15-25 grams ntawm hmoov rau 100 grams dej, sib raug rau qhov concentration ntawm kwv yees li 13% -20%. Qhov ntau no ua kom muaj kev zom cov khoom tsis huv xws li xeb thiab limescale thaum tsis txhob xeb rau feem ntau cov substrates. Cov ntaub ntawv sim qhia tau tias thaum qhov concentration tshaj 25%, qhov corrosion ntawm stainless hlau nce ntxiv exponentially.
Cov tshuaj uas tau npaj ua ntej lawm yuav tsum tau muab diluted siv txoj kev stepwise. Pom zoo kom dilute 30% cov tshuaj stock ntawm qhov sib piv ntawm 1:5 txog 1:10 (cov tshuaj stock: dej) kom tau 3%–5% cov tshuaj ua haujlwm. Yuav tsum dilute 50% cov tshuaj stock ntawm qhov sib piv ntawm 1:10 txog 1:20 kom tau qhov concentration ntawm 2.5%–5%. Qhov kev dilution stepwise no ua kom cov tshuaj tseem zoo ib yam thiab ruaj khov, tiv thaiv kev sib xyaw ntau dhau hauv zos.
Zibo Anhao Chemical Co., Ltd. - Oxalic Acid
Zibo Anhao Chemical Co., Ltd. yog ib lub tuam txhab muag khoom oxalic acid (CAS 144-62-7) uas muaj cov tshuaj oxalic acid ntshiab (CAS 144-62-7), uas tseem hu ua ethanedioic acid, nrog rau cov mis molecular C₂H₂O₄. Ua ib qho dicarboxylic acid yooj yim tshaj plaws, nws zoo li cov khoom dawb, tsis muaj ntxhiab, yaj tau hauv dej thiab ethanol, nrog cov kua qaub muaj zog thiab cov khoom chelating zoo heev. Peb cov khoom muaj nyob rau hauv ob qho tib si anhydrous thiab dihydrate, ua raws li cov lus qhia nruj ntawm kev lag luam thiab qib siab kom ntseeg tau tias ≥99.6% ntshiab thiab kev ua haujlwm zoo ib yam.
Oxalic acid yog ib qho tshuaj siv tau ntau yam hauv kev lag luam thoob plaws ntau yam kev lag luam. Hauv kev ua hlau, nws ua haujlwm ua tus neeg tshem xeb tseem ceeb, tus neeg ntxuav nplai, thiab tus neeg sawv cev kho qhov chaw hlau, ua kom hlau thiab lwm yam hlau ions chelating zoo. Hauv kev lag luam textile thiab tawv, nws yog siv rau kev ua kom dawb, zas xim pab, thiab cov txheej txheem deliming. Nws kuj tseem ua lub luag haujlwm tseem ceeb hauv kev rho tawm cov av tsis tshua muaj, kev ua kom dawb ceramic, kev tsim tshuaj, thiab kev tsim cov ntsev oxalate xws li cobalt oxalate thiab lithium oxalate. Tsis tas li ntawd, nws ua haujlwm ua tus neeg sawv cev ntxuav rau cov ntaub ntawv tsim kho thiab cov tshuaj dawb ntoo hauv kev lag luam rooj tog.
Ntawm Zibo Anhao Chemical, peb muab qhov tseem ceeb rau kev tswj xyuas zoo thiab kev tsim khoom ruaj khov. Peb cov oxalic acid yog tsim los ntawm cov txheej txheem txheem nrog kev kuaj xyuas nruj ntawm txhua theem, ua raws li ISO thiab cov qauv kev lag luam thoob ntiaj teb. Peb muab cov kev xaiv ntim khoom yooj ywm, suav nrog 25kg hnab yas-lined woven thiab 50kg nruas, kom ntseeg tau tias muaj kev nyab xeeb cia thiab kev thauj mus los. Nrog rau cov peev xwm muab khoom muaj zog thiab ntau xyoo ntawm kev xa khoom tawm, peb muab cov khoom lag luam ruaj khov, kev sib tw nqi, thiab kev txhawb nqa kev txawj ntse rau cov neeg siv khoom thoob ntiaj teb, txhawb kev koom tes txhim khu kev qha thiab ntev.
