Teem-Accelerator-Calcium Formate

Calcium formate tuaj yeem ua tau raws li qhov chaw accelerator hauv pob zeb. Nov yog qhov nws ua haujlwm li cas:

Teem Acceleration Mechanism:

1. Cov txheej txheem dej: Thaum calcium formate ntxiv rau cov pob zeb sib tov, nws yaj hauv dej thiab tso cov calcium ions (Ca^2+) thiab formate ions (HCOO^-).
2. Txhawb kev tsim CSH: Cov calcium ions (Ca^2+) tso tawm los ntawm calcium formate react nrog cov silicates hauv cov cement, ua kom cov calcium silicate hydrate (CSH) gel. Qhov CSH gel no yog thawj binder hauv pob zeb, lub luag haujlwm rau nws lub zog thiab kav ntev.
3. Lub Sijhawm Teeb Meem Ceev: Kev tsim kom nrawm ntawm CSH gel ua rau lub sijhawm teem sijhawm sai dua rau cov pob zeb sib xyaw. Qhov no tso cai rau kom ua tiav sai dua thiab tshem tawm ua ntej ntawm formwork, ua kom cov txheej txheem tsim kho tag nrho.

Cov txiaj ntsig ntawm Kev Siv Calcium Formate ua qhov teeb tsa Accelerator:

1. Txhim kho Thaum Ntxov Muaj Zog: Lub zog thaum ntxov ntawm cov pob zeb yog txhim kho vim yog cov txheej txheem hydration ceev tau yooj yim los ntawm calcium formate. Qhov no tuaj yeem tau txais txiaj ntsig tshwj xeeb hauv cov huab cua txias uas pom lub sijhawm qeeb qeeb.
2. Txo Lub Sijhawm Tsim Kho: Los ntawm kev ua kom lub sijhawm teem sijhawm ntawm pob zeb, calcium formate pab txo lub sijhawm tsim kho thiab tso cai rau kev ua tiav sai dua.
3. Txhim Kho Kev Ua Haujlwm Zoo: Calcium formate tuaj yeem txhim kho kev ua haujlwm ntawm pob zeb, ua kom yooj yim rau kev tuav thiab qhov chaw, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas yuav tsum tau ceev ceev.

Daim ntawv thov hauv pob zeb:

• Calcium formate feem ntau yog ntxiv rau cov pob zeb sib xyaw ntawm qhov ntau npaum li ntawm 0.1% mus rau 2% los ntawm qhov hnyav ntawm cov cement, nyob ntawm seb lub sijhawm xav tau thiab kev ua tau zoo.
• Nws feem ntau yog siv rau hauv precast qhob ntau lawm, daim ntawv thov txhaj tshuaj, thiab kev tsim kho cov haujlwm uas yuav tsum tau teeb tsa sai.

Kev txiav txim siab:

• Thaum calcium formate tuaj yeem ua kom lub sijhawm teem sijhawm ntawm pob zeb, nws yog ib qho tseem ceeb kom ua tib zoo xav txog cov nqi ntau npaum li cas thiab kev sib raug zoo nrog lwm cov khoom siv kom tsis txhob muaj kev cuam tshuam rau cov khoom vaj khoom tsev.
• Kev tswj xyuas kev ua tau zoo yuav tsum tau ua los xyuas kom meej tias cov pob zeb nrawm nrawm tswj tau lub zog xav tau, ua haujlwm ntev, thiab cov yam ntxwv ua haujlwm.

Calcium formate ua hauj lwm pab raws li ib tug zoo chaw accelerator nyob rau hauv pob zeb, txhawb kom ceev hydration thiab thaum ntxov zog kev loj hlob. Nws siv tuaj yeem pab ua kom lub sijhawm tsim kho sai thiab txhim kho kev ua haujlwm, tshwj xeeb tshaj yog nyob rau hauv huab cua txias lossis lub sijhawm ua haujlwm. Txawm li cas los xij, kev siv ntau npaum li cas thiab kev sib raug zoo yog qhov tseem ceeb rau kev ua tiav cov yam ntxwv uas xav tau thaum siv calcium formate ua tus accelerator.
