Kev txhim kho keeb kwm ntawm qhob tsa admixtures
Nyob rau hauv xyoo tsis ntev los no, nrog kev txhim kho ceev ceev ntawm cov vaj tse kev lag luam thiab kev tsim kho cov khoom siv tau ua cov khoom muaj zog, thiab tsim lub zog ntawm cov pob zeb tau nce ntxiv. Cov neeg rho nyiaj li yav dhau los dej reducers thiab naphthalene sulfonate-based superfasticizer snf dej uas muaj cov ua haujlwm txo cov khoom lag luam, uas tsis tuaj yeem ua tiav cov kev tsim kho. Txhawm rau txuag lub zog thiab txo qhov hnyav rau tus kheej ntawm cov tuam tsev, lub zog qib ntawm cov qauv siv hauv tsev tau nce siab dua thiab siab dua. Kev muaj zog thiab kev ua haujlwm siab qhob admixtures kom muaj dej siab txo thiab txhim kho kev ua haujlwm ntawm cov pob zeb ua.
Qhov kev thov ntawm engineering thiab kev ua lag luam tau nce rau cov dej thib peb ntawm kev ua tau zoo dej reducer - polycarboxylate superplasticerizylate superplasticerizylate super reducer. Piv nrog cov tsoos dej nyob ib txwm muaj xws li Sudium Nafethoence Sulfonate (SnF) Zoo tuav ntawm lub fluidity ntawm pob zeb ua ke; Kev sib xyaw zoo nrog cov cement; Me me shrinkage ntawm qhob npaj, uas yog qhov ua kom zoo rau kev txhim kho lub ntim ruaj khov thiab lub zog ntawm cov pob zeb ua; Cov phooj ywg ib puag ncig thiab cov pa phem-dawb thaum muaj kev tsim khoom thiab siv, koom nrog ntsuab thiab ib puag ncig admixtures. Nws yog qhov tseeb vim tias cov khoom zoo tshaj plaws uas polycarboxylate superplasticer pce muaj ntau siv cov roj teeb uas muaj kev tsim kho.
Polycarboxylate SuperPlasticizer PCE Cov Dej Kub Ua Si Siv Dej Ntaus Cov Tshuab
Lub ntsiab ntawm polycarboxylate superplasticizer pce siab cov dej ntws tsawg
Polycarboxylate Superplasticizer pce Siab Rev Dej Reven Tus Neeg Sawv Cev Feem ntau yog suav nrog poly-carboxylate superplastic niam cov kua thiab ntau yam kev sib ntxiv. Vim tias cov kev tsim tawm sib txawv ntawm txhua yam kev tsim kho ntawm cov xuab zeb thiab cov khoom sib xyaw ua ke los ntawm cov neeg siv khoom sib xyaw ua ke raws li cov neeg siv khoom kom tau raws li cov neeg siv khoom ntawm txhua tus neeg yuav khoom. Cov khoom siv raw tseem ceeb hauv cov txheej txheem sib xyaw ua ke suav nrog: polycarboxylate cov cai, cov khoom siv cua sov, txhua cov khoom siv ua si hauv lub luag haujlwm tseem ceeb hauv cov txheej txheem sib xyaw.
kev ua haujlwm ntawm lub ntsiab ntawm polyacrylate superplasticizer pce siab cov dej reducer
Tam sim no, muaj plaub hom polycarboxylate superplasticer kua kua rau kua, ib qho yog cov kua dej siab li kua kua, thiab ib qho yog thaum ntxov lub zog hom kua.
Qee zaum, raws li cov neeg siv khoom muaj, cov niam txiv tau sib xyaw ua ke kom tau txais cov dej sib xyaw ua ke kom tau txais kev ua tau zoo dua thiab ntsib cov neeg siv khoom. Txhua yam niam cov kua ua kua rau lwm lub luag haujlwm hauv kev sib xyaw.
- Thaum cov dej-txo tus nqi ntawm cov compounded polycarboxylate superplasticer pce yog tsawg thiab cov nqi txo tau los txhim kho cov dej txo cov dej;
- Thaum ntsib kev kub siab nyob rau lub caij ntuj sov thiab tsis txaus siab rau kev ua tau zoo, khaws cov khoom ua kom zoo nkauj
- Thaum ntsib kev sib tw ntau dhau cov ntaub ntawv thiab cov av nkos siab hauv admixature los ntawm admixture los ntawm cov pob zeb ua hmoov av thiab av nkos;
- Thaum ntsib kev mob siab txias heev lossis xav tau lub zog thaum ntxov ua rau muaj lub zog thaum ntxov rau cov lus teb ntawm lub admixture los txhim kho lub zog thaum ntxov. Tsuas yog los ntawm kev siv cov diversified polycarboxylate superplastic niam niam ua ke nrog cov khoom lag luam zoo tagnrho. Los ntawm kev sib xyaw ntawm kev ua tau sib txawv niam kua, kev ua tau zoo ntawm cov khoom tuaj yeem hloov kho, kev ua tau zoo thiab txhim kho cov khoom ua haujlwm tsis muaj tseeb ntawm cov khoom lag luam.
