Qhov ntsuas kub qis dua, qhov tseem ceeb tshaj qhov cuam tshuam thaum ntxov ntawm calcium formate, thiab qhov ntau npaum li cas tuaj yeem txo qis rau lub caij ntuj sov.
Calcium formate yog siv los ua calcium chiv thiab av hloov kho hauv kev ua liaj ua teb, nrog rau kev ua haujlwm ntawm calcium ntxiv, tswj cov av acidity thiab alkalinity, thiab txhawb cov qoob loo loj hlob. Cov ntsiab lus calcium nyob rau hauv calcium formate tau yooj yim nqus los ntawm cov nroj tsuag thiab tuaj yeem tiv thaiv kab mob ntawm lub cev los ntawm calcium deficiency nyob rau hauv cov qoob loo, xws li txiv lws suav navel rot thiab kua iab pob txuv. Qhov tsis muaj zog acidity ntawm calcium formate tuaj yeem cuam tshuam cov av alkaline, txhim kho cov qauv av, thiab txhim kho av fertility. Piv txwv li, foliar spraying: diluted thiab sprayed on qoob loo nplooj kom sai sai ntxiv calcium ntsiab. Daim ntawv thov chiv: tov nrog cov organic chiv thiab siv rau hauv av los txhim kho cov av ib puag ncig. Thaum ua ntawv thov ib txhij, kev hloov kho yuav tsum tau ua raws li cov av hom thiab cov qoob loo uas yuav tsum tau ua kom tsis txhob muaj av acidification ntau dhau. Cov nyhuv ntawm daim ntawv thov yog zoo dua thaum lub sij hawm tseem ceeb ntawm cov qoob loo loj hlob, xws li flowering thiab fruiting.
Tawv kev lag luam
Calcium formate, ua tus neeg sawv cev tanning thiab neutralizer hauv kev tsim cov tawv nqaij, tuaj yeem txhim kho softness, elasticity, thiab durability ntawm tawv. Calcium formate khi nrog collagen nyob rau hauv tawv kom tsim ib tug ruaj khov ntoo khaub lig-txuas qauv, txhim khu lub cev zog ntawm tawv. Calcium formate tuaj yeem kho tus nqi pH thaum lub sijhawm tawv dyeing thiab ua tiav cov txheej txheem kom ntseeg tau tias txawm tias adhesion ntawm dyes thiab cov neeg ua tiav. Piv txwv li, high- tawv tawv: siv los ua khau tawv, tsho tawv tawv, khoom tawv tawv, thiab lwm yam, los txhim kho cov khoom zoo. Muaj tawv tawv: siv rau lub rooj zaum hauv tsheb, rooj zaum, thiab lwm yam. Thaum lub sij hawm tanning txheej txheem, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj qhov kub, lub sij hawm, thiab pH tus nqi kom tsis txhob tawv tawv dhau los yog deformed. Kev siv cov calcium formate yuav tsum ua raws li ib puag ncig cov qauv thiab txo cov dej khib nyiab.
Calcium formate, raws li ib tug drilling kua additive nyob rau hauv roj av drilling, tuaj yeem txhim kho stability thiab lubricity ntawm drilling kua. Calcium formate tuaj yeem kho tus nqi pH ntawm cov kua dej drilling, tiv thaiv qhov dej tawg, thiab ua kom muaj kev nyab xeeb ntawm qhov drilling. Txo qhov kev sib txhuam ntawm lub laum me ntsis thiab lub pob zeb, txhim kho kev ua haujlwm ntawm drilling, thiab txuas ntxiv lub neej kev pab cuam ntawm lub laum ntsis. Piv txwv li, nyob rau hauv qhov tob tob drilling, calcium formate tuaj yeem tswj kev ruaj ntseg ntawm kev ua haujlwm ntawm cov dej hauv qhov kub thiab txias. Shale gas kev loj hlob: tiv thaiv shale hydration thiab nthuav dav, thiab tsis txhob muaj qhov tsis txaus ntseeg. Nyob rau tib lub sijhawm, nws yuav tsum tau siv ua ke nrog lwm cov kua dej ntxiv kom tsis txhob muaj sedimentation lossis stratification. Tom qab drilling tiav lawm, cov dej khib nyiab drilling yuav tsum tau kho tsis zoo.
zaub mov kev lag luam & Lwm yam kev siv

Peb yog cov chaw tsim khoom calcium formate. Peb siv peb tus kheej txoj kev tsim khoom los ua calcium formate wholesale.
Synthetic calcium formate:
1. Neutralization txoj kev
Kev lag luam calcium formate yog tau los ntawm neutralizing formic acid nrog hydrated txiv qaub los tsim calcium formate
2. Compound decomposition txoj kev
Nyob rau hauv lub xub ntiag ntawm catalyst, sodium formate reacts nrog calcium nitrate los tsim calcium formate thiab sodium nitrate. Kev lag luam calcium formate tau los ntawm kev ua kom zoo.
3. Epoxy fatty acid methyl ester los ntawm -cov txheej txheem khoom
Kev tsim cov epoxy fatty acid methyl ester txhim kho sai. Ntau npaum li cas los ntawm - cov khoom formic acid yuav raug tsim thaum lub sij hawm tsim cov khoom no. Ib txoj kev siv ntawm qhov no los ntawm - cov khoom formic acid yog tsim cov calcium formate.
4. Pentaerythritol los ntawm - cov txheej txheem khoom

Lub discovery ntawmCalcium Formate hmoovyog ze ze rau txoj kev loj hlob ntawm chemical science. Nyob rau hauv lub lig 18th thiab thaum ntxov 19th centuries, chemists pib systematically kawm cov khoom thiab kev npaj ntawm inorganic tebchaw. Formic acid (HCOOH), raws li qhov yooj yim carboxylic acid, tau los ntawm distilling ntsaum thaum ntxov li xyoo pua 17th thiab tau lub npe hu ua "formic acid" vim nws thaum ntxov extraction los ntawm ntsaum. Cov tshuaj lom neeg ntawm formic acid tau maj mam tshwm sim, tab sis txoj kev tshawb fawb ntawm nws cov ntsev lags qab cov kua qaub nws tus kheej. Nyob rau hauv 1789, Fabkis chemist Antoine Laurent de Lavoisier thawj zaug faib cov ntsiab lus rau hauv gases, hlau, tsis yog hlau, thiab alkaline ntiaj teb hlau nyob rau hauv nws ua hauj lwm, nteg lub hauv paus rau kev tshawb fawb tom ntej. Txawm li cas los xij, thaum lub sijhawm ntawd, kev nkag siab ntawm alkaline ntiaj teb hlau (xws li calcium) tseem txwv rau cov ntaub ntawv ntxhia (xws li limestone), thiab kev tshawb fawb txog lawv cov ntaub ntawv tseem ceeb thiab cov ntaub ntawv tseem tsis tau ua.
Thaum pib ntawm lub xyoo pua 19th, British chemist Humphry Davy tau cais ntau yam alkali hlau thiab alkaline ntiaj teb hlau los ntawm electrolysis, uas txhawb nqa qhov tseem ceeb ntawm kev npaj calcium formate. Xyoo 1808, David tau ua tiav cov calcium amalgam los ntawm electrolyzing sib tov ntawm txiv qaub (CaO) thiab mercury oxide (HgO), thiab tom qab ntawd sib cais cov hlau calcium los ntawm distillation. Qhov kev ua tiav no tsis yog tsuas yog tsim kom muaj cov calcium uas muaj nyob hauv ib qho kev ywj pheej, tab sis kuj tseem muab cov ntaub ntawv raw rau kev npaj cov calcium ntsev tom ntej. David txoj kev electrolysis yog ua raws li kev tsim tawm ntawm Voltaic Pile, uas siv cov tam sim no ncaj qha los decompose cov tebchaw hauv molten lossis tov. Txawm hais tias qhov kev sim thaum ntxov yog rudimentary (xws li siv platinum electrodes thiab cov khoom siv hluav taws xob tsis zoo), David tau txhim kho qhov ua tau zoo ntawm cov nag lossis daus los ntawm kev ua kom zoo dua cov electrolyte muaj pes tsawg leeg (xws li ntxiv mercury los tsim mercury amalgam). Cov thev naus laus zis no tau siv dav hauv kev tsim cov hlau xws li sodium, potassium, thiab magnesium. Nyob rau hauv lub xyoo pua 20th, cov tshuab tsim cov calcium formate underwed ob loj nrhav:
- Optimization of Neutralization Method: Nyob rau hauv lub xyoo pua 20th, chemists tau txhim kho cov purity ntawm calcium formate (mus txog 98%) los ntawm kev nruam crystallization thiab recrystallization cov tswv yim, thiab tsim reactors haum rau loj - teev ntau lawm.
- Industrialization ntawm ob txoj kev decomposition: Hauv xyoo 1950, nrog rau kev txhim kho ntawm ion exchange membrane technology, cov txiaj ntsig ntawm cov tshuaj tiv thaiv ob zaug decomposition tau zoo heev thiab cov nqi tsim khoom raug txo. Calcium formate pib dav siv los ua cov khoom siv hauv tsev (xws li cement thaum ntxov zog tus neeg sawv cev) thiab pub additive.
Hauv kev tsim kho, calcium formate ua tus neeg sawv cev muaj zog thaum ntxov tuaj yeem ua kom cov cement hydration cov tshuaj tiv thaiv, txhim kho lub zog thaum ntxov, thiab tshwj xeeb tshaj yog tsim rau qis - qhov kub thiab txias. Hauv kev lag luam pub khoom noj, calcium formate txhawb nqa cov kab mob uas muaj txiaj ntsig zoo thiab ua kom cov zaub mov hloov pauv los ntawm kev tswj hwm tus nqi pH ntawm tus tsiaj plab hnyuv.
Calcium formate hmoov yog ntau yam thiab muaj txiaj ntsig zoo nrog ntau daim ntawv thov thoob plaws ntau yam kev lag luam. Nws cov khoom siv tshuaj tshwj xeeb, suav nrog solubility, stability, thiab reactivity, ua rau nws yog ib qho tseem ceeb additive nyob rau hauv kev tsim kho, kev ua liaj ua teb, tawv ua, thiab lwm yam sectors.
