Calcium Formate: Ib qho tshuaj lom neeg zoo uas muaj zog rau ntau yam kev lag luam
Calcium formate (tshuaj mis: Ca(HCOO)₂), yog ib hom hmoov dawb crystalline uas muaj ntxhiab tsw ntawm formic acid me ntsis, yog ib yam khoom siv tshuaj zoo uas muaj nqis heev thiab tau txais kev nyiam thoob plaws ntiaj teb. Nws muaj kev ruaj khov zoo heev, yaj tau hauv dej, thiab tsis ua rau ib puag ncig puas tsuaj, thiab nws tau tshwm sim los ua ib yam khoom siv tseem ceeb hauv kev ua liaj ua teb thiab kev tsim kho mus rau kev tiv thaiv ib puag ncig thiab tshuaj. Nws cov khoom siv tshuaj tshwj xeeb—xws li tsis muaj tshuaj lom, tiv taus corrosion, thiab biodegradability—ua raws li qhov kev thov ntawm cov khoom siv ruaj khov thiab ua tau zoo, ua rau nws nrov zuj zus hauv kev lag luam ib txwm muaj thiab kev lag luam tshiab.
Cov Khoom Tseem Ceeb thiab Cov Qauv Tsim Khoom
Feem ntau, calcium formate muaj qib purity ntawm 98% lossis siab dua, nrog rau cov cim qhia tseem ceeb suav nrog cov dej noo tsawg (≤0.5%), cov hlau hnyav tsawg kawg nkaus (Pb, As, Cd ≤10ppm), thiab kev faib tawm qhov loj me sib npaug. Cov lus qhia no ua kom nws ntseeg tau hauv cov ntawv thov tseem ceeb, vim tias cov dej noo tuaj yeem ua rau cov khoom tsis zoo - piv txwv li, cov dej noo ntau dhau yuav cuam tshuam rau nws qhov ua tau zoo ua cov desiccant lossis binder. Hauv kev lag luam, nws feem ntau yog tsim los ntawm kev sib xyaw ntawm calcium oxide lossis calcium hydroxide nrog formic acid, ib qho txheej txheem uas hais txog kev siv hluav taws xob zoo thiab kev txo cov khib nyiab kom ua tau raws li cov qauv ib puag ncig thoob ntiaj teb xws li ISO 9001 thiab REACH. Cov calcium formate zoo kuj yuav tsum ua kom pom kev ruaj khov thermal zoo heev, tswj nws cov khoom txawm tias nyob rau hauv cov xwm txheej ua haujlwm kub siab (txog li 300 ° C), ua rau nws haum rau ntau yam txheej txheem tsim khoom.
Cov Ntawv Thov Sib Txawv Thoob Plaws Cov Lag Luam Tseem Ceeb
1. Cov Khoom Noj Ntxiv: Txhim Kho Kev Noj Qab Haus Huv thiab Kev Noj Qab Haus Huv ntawm Tsiaj
Ua ib yam khoom noj khoom haus ntxiv, calcium formate ua ob lub luag haujlwm ua ib yam khoom noj khoom haus ntxiv calcium thiab ib yam khoom txhawb kev loj hlob. Nws cov calcium uas muaj bioavailable heev txhawb nqa kev loj hlob ntawm pob txha thiab kev tsim cov qe hauv cov nqaij qaib thiab tsiaj txhu, thaum nws cov format ions pab tswj cov pH hauv plab hnyuv, tiv thaiv kev loj hlob ntawm cov kab mob phem (piv txwv li, Escherichia coli, Salmonella) thiab txhim kho kev nqus cov as-ham. Tsis zoo li cov calcium ib txwm muaj xws li limestone, calcium formate tsis hloov pauv qhov saj ntawm cov khoom noj thiab sib xws nrog lwm yam khoom ntxiv, ua rau nws yog ib qho kev xaiv zoo rau kev ua liaj ua teb hnyav. Nws yog siv dav hauv kev noj haus rau npua, qaib, thiab cov tsiaj txhu aquaculture, pab txhawb rau qhov hnyav nce ntxiv, txo cov neeg tuag, thiab txhim kho kev hloov pauv zaub mov.
2. Cov Khoom Siv Tsim Kho: Kev Ua Kom Zoo Dua Qhov Ua Tau Zoo ntawm Cov Pob Zeb
Hauv kev lag luam kev tsim kho, calcium formate ua haujlwm ua tus ua kom nrawm nrawm thiab tiv thaiv kev khov. Los ntawm kev txhawb nqa kev ua kom cov cement clinker minerals hydration, nws ua rau lub sijhawm teeb tsa ntawm cov pob zeb ua vaj tse luv dua - tseem ceeb rau cov haujlwm uas xav tau kev tshem tawm cov formwork sai lossis kev tsim kho hauv qhov chaw kub qis (mus txog -10 ° C). Tsis tas li ntawd, nws txhim kho kev txhim kho lub zog ntawm cov pob zeb ua vaj tse, tshwj xeeb tshaj yog nyob rau theem thaum ntxov, thiab txhim kho kev ruaj khov los ntawm kev txo cov porosity thiab ua rau muaj kev tiv thaiv rau cov voj voog khov-thaw. Nws cov ntsiab lus chloride qis tshem tawm qhov kev pheej hmoo ntawm kev xeb hlau, ua rau nws zoo tagnrho rau kev siv hauv cov choj, qhov av, cov tsev siab, thiab cov khoom siv pob zeb ua ntej. Nws kuj pom daim ntawv thov hauv cov mortars qhuav thiab cov nplaum pobzeb, txhim kho kev ua haujlwm thiab kev nplaum.
3. Kev Tiv Thaiv Ib Puag Ncig: Pab Kom Desulfurization Zoo
Calcium formate tau dhau los ua lwm txoj hauv kev ruaj khov rau cov neeg sawv cev desulfurization ib txwm muaj (piv txwv li, limestone) hauv kev kho cov pa roj flue. Hauv cov txheej txheem desulfurization roj flue uas muaj sulfur ntau, nws cuam tshuam nrog sulfur dioxide (SO₂) los tsim cov calcium sulfite thiab calcium sulfate ruaj khov, uas tuaj yeem rov ua dua tshiab ua cov khoom lag luam. Cov txheej txheem no muab kev ua haujlwm desulfurization siab dua (ntau dua 95%), kev siv hluav taws xob tsawg dua, thiab txo cov sludge tsim piv rau cov txheej txheem ib txwm muaj. Nws yog qhov tshwj xeeb tshaj yog rau cov chaw tsim hluav taws xob, cov chaw tsim hlau, thiab cov chaw tsim tshuaj uas nrhiav kev ua raws li cov qauv kev tso pa phem nruj (piv txwv li, EU Industrial Emissions Directive, Tuam Tshoj GB 13223-2011), pab txhawb rau kev siv zog thoob ntiaj teb los txo cov pa phem.
4. Lwm yam kev siv hauv kev lag luam thiab tshuaj
Dhau ntawm cov haujlwm tseem ceeb, calcium formate ua lub luag haujlwm tseem ceeb hauv ntau yam kev siv tshwj xeeb. Ua tus binder hauv kev tsim cov cib carbon, nws txhim kho lub zog thiab qhov ceev ntawm cov khoom siv refractory siv hauv cov cub tawg metallurgical. Hauv kev ua liaj ua teb, nws ua haujlwm ua tus tswj kev loj hlob ntawm cov nroj tsuag, txhim kho kev tiv thaiv kev ntxhov siab thiab cov qoob loo hauv cov qoob loo xws li nplej thiab pob kws. Hauv kev lag luam tshuaj, nws yog siv ua cov khoom xyaw nquag hauv cov tshuaj calcium hauv qhov ncauj, muab cov khoom siv calcium mos mos thiab yooj yim nqus tau rau kev kho cov calcium tsis txaus hauv tib neeg - ntau cov khoom calcium uas yuav tsis tas yuav muaj ntawv yuav khoom vam khom calcium formate rau nws cov bioavailability siab thiab tsawg kawg nkaus kev khaus plab hnyuv. Nws kuj ua haujlwm ua cov khoom siv raw hauv kev tsim cov tshuaj tua kab, cov neeg sawv cev tawv tanning, thiab cov khoom noj khoom haus preservatives.
