Abstract:
Pob zeb yog cov khoom siv hauv tsev uas siv dav hauv kev tsim kho vim nws lub zog, durability thiab versatility.Ntau yam khoom siv ntxiv tau ua haujlwm los txhim kho cov khoom vaj khoom tsev thiab daws cov teeb meem tshwj xeeb cuam tshuam nrog nws cov khoom tsim thiab kev siv.Ib qho ntxiv ntawm kev txaus siab yog calcium formate, ib qho kev sib xyaw nrog cov khoom tshwj xeeb uas pab txhim kho cov khoom vaj khoom tsev.
qhia:
Pob zeb yog cov khoom sib xyaw ua ke ntawm cov cement, aggregate, dej thiab admixtures thiab yog cov pob txha ntawm kev tsim kho niaj hnub.Hauv kev tshawb nrhiav cov khoom siv tshiab los txhim kho cov khoom vaj khoom tsev, calcium formate, ib qho chaw muab tau los ntawm formic acid thiab calcium carbonate, tau tshawb nrhiav.Cov kab lus no txhawm rau kom nkag siab tob txog qhov cuam tshuam ntawm calcium formate ntawm pob zeb, qhia nws cov khoom, qhov zoo thiab ntau yam kev siv.
Cov khoom ntawm calcium formate:
chemical muaj pes tsawg leeg:
Calcium formate yog dej-soluble ntsev uas muaj calcium ions (Ca2+) thiab formate ions (HCOO-).
Nws cov tshuaj formula yog Ca (HCOO) 2.
Solubility:
Calcium formate nthuav tawm siab solubility hauv dej, uas ua rau nws yooj yim dispersion thoob plaws hauv cov pob zeb sib tov.
Kev ywg dej:
Thaum lub sij hawm hydration txheej txheem, calcium formate pab tsim cov khoom hydration ntxiv uas cuam tshuam rau microstructure ntawm pob zeb.
Qhov zoo ntawm Calcium Formate hauv pob zeb:
Accelerated lub sij hawm:
Calcium formate ua raws li lub accelerator, shortening lub sij hawm teem ntawm pob zeb.Qhov no tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv huab cua txias qhov chaw ncua sij hawm tuaj yeem ua rau muaj teeb meem.
Ua kom muaj zog:
Lub xub ntiag ntawm calcium formate txhim khu lub zog thaum ntxov thiab zaum kawg ntawm cov pob zeb, yog li kev txhim kho cov qauv kev ua haujlwm.
Txo los ntshav thiab sib cais:
Calcium formate pab txo cov ntshav thiab kev sib cais, txhawb kev sib koom ua ke hauv kev sib xyaw ua ke.
Txhim kho machinability:
Kev sib xyaw ua ke ntawm calcium formate feem ntau qhia txog kev ua haujlwm zoo dua qub, ua kom yooj yim rau kev tswj thiab qhov chaw thaum siv.
Mitigating Frost puas:
Hauv cov huab cua txias, qhov sib ntxiv ntawm calcium formate tuaj yeem pab txo qis kev puas tsuaj los ntawm kev ua kom lub sijhawm teem sijhawm thiab txo qhov tsis zoo ntawm cov pob zeb kom khov-thaw mus.
Kev siv calcium formate hauv pob zeb:
Cov huab cua txias pob zeb pouring:
Calcium formate feem ntau yog siv nyob rau hauv huab cua txias qhov chaw tso rau hauv counteract qhov tsis zoo ntawm qhov kub thiab txias ntawm qhov chaw thiab txheej txheem kho.
Kev kho sai:
Hauv cov ntawv thov uas xav tau kev kho sai, xws li kev kho thaum muaj xwm txheej ceev lossis kev kho vaj tse, siv calcium formate tuaj yeem ua kom lub sijhawm tsim kho.
Precast qhob ntau lawm:
Lub sijhawm teem sijhawm nrawm thiab kev txhim kho lub zog cuam tshuam nrog calcium formate ua rau nws tsim nyog rau precast qhob ntau lawm qhov twg ceev tig lub sij hawm yog qhov tseem ceeb.
High kev ua tau zoo pob zeb:
Calcium formate pab tsim cov pob zeb ua haujlwm siab nrog kev txhim kho durability thiab lub zog, ua rau nws tsim nyog rau cov phiaj xwm tseem ceeb.
Cov kev sib tw thiab kev txiav txim siab:
Kev xav txog tus nqi:
Txawm hais tias calcium formate muaj ntau qhov zoo, nws cov nqi yuav yog qhov tseem ceeb rau kev txiav txim siab hauv koj qhov project pob nyiaj siv.
Dose Optimization:
Qhov zoo tshaj plaws ntawm calcium formate yuav tsum tau txiav txim siab raws li cov kev xav tau tshwj xeeb, suav nrog ntau yam xws li kev sib xyaw tsim, ib puag ncig thiab cov khoom tsim nyog.
nyob rau hauv xaus:
Hauv cov ntsiab lus, calcium formate tawm los ua ib qho tseem ceeb ntxiv hauv kev siv tshuab ua vaj tse, muab cov txiaj ntsig zoo uas daws cov teeb meem cuam tshuam nrog kev tsim khoom thiab kev siv.Los ntawm kev teeb tsa sai dua rau kev txhim kho lub zog thiab ua haujlwm tau zoo, calcium formate cov khoom siv ntau yam ua rau nws muaj kev vam meej rau ntau yam kev tsim kho.Raws li kev tshawb fawb txuas ntxiv thiab thev naus laus zis nce ntxiv, kev koom ua ke calcium formate rau hauv cov pob zeb sib xyaw ua ke tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv thiab kev coj ua yav tom ntej.
