Qhob admixtures, raug xa mus ua admixtures rau luv, xa mus rau cov tshuaj ntxiv ua ntej lossis lub sij hawm ua kom sib xyaw ua ke los txhim kho cov khoom ntawm cov qhob ua tshiab thiab / lossis tawv tawv tawv. Cov yam ntxwv ntawm cov pob zeb ua qauv zoo nkauj yog ntau yam thiab
Cov tshuaj tsawg, uas ua lub luag haujlwm tseem ceeb hauv kev hloov pauv. Nrog rau cov chav kawm dav dav ntawm kev tsim kho kev tsim kho, qhov kev thov rau cov pob zeb ua txuas ntxiv, thiab tib lub sijhawm, muaj ntau dua rau kev ua tau zoo thiab ua tau zoo ntawm kev ua vaj tse. Hauv cov ntsiab lus no, raws li cov ntaub ntawv tseem ceeb engineering uas tuaj yeem txhim kho kev ua tau zoo ntawm cov pob zeb ua kom zoo nkauj niaj hnub no, xuab zeb, pob zeb thiab dej.
Kev ua haujlwm hauv dej siab-txo cov dej-txo tus neeg sawv cev yog feem ntau muab faib ua peb pawg, high-effecticiency dej-txo tus neeg saib xyuas thiab kev ua haujlwm siab dej-txo tus neeg sawv cev. Kev txhim kho ntawm superplasticizers tau dhau mus los ntawm peb theem: thawj tiam ntawm superplasticizers muaj sawv cev los ntawmNtoo Calcium, lub cim thib ob ntawm superplasticizers sawv cev los ntawmnaphthaleneseries, thiab lub cim thib peb ntawm superplasticizers sawv cev los ntawmPolycarboxylate Superplasticizerseries. Tiam ntawm kev ua haujlwm siab superplasticer theem.Polycarboxylate Superplasticizermuaj qhov zoo ntawm cov tshuaj qis thiab dej txo qis, thiab siv tau kom muaj lub siab dua, ultra-zog, siab ntev thiab ua pa roj av; Cov txheej txheem tsis muaj cov kua dej pov tseg, khib nyiab pov tseg, khib nyiab tsis txaus thiab lwm yam. Nws yog xim ntsuab thiab ib puag ncig cov dej ntws tsawg, thiab muaj qhov zoo ntawm kev tiv thaiv ib puag ncig thiab kev ua tau zoo. Nrog kev nthuav dav ntawm kev tsim khoom thiab kev txhim kho ntawm permeability, polycarboxylate superplasticizers tam sim no tsim thiab noj hauv kuv lub tebchaws.
Nyob rau hauv cov ntsiab lus ntawm "Kev Loj Hlob Zoo Li Cas" yuav nce ntxiv rau cov chaw tsim khoom tsim tau los ntawm cov khoom tsim kho tib lub sijhawm. Tsis tas li ntawd, raws li tsoomfwv cov ntaub ntawv tshaj tawm ua haujlwm xws li cov phiaj xwm kev thauj mus los thiab cov haujlwm saum toj no muaj rau cov khoom ua vaj tse, thiab kev ua haujlwm siab Reducers yuav tsum tau ua kom tau raws li cov cai ntawm cov pob zeb ua. Piv nrog rau lwm hom kev siv incixtures, kev nqus cov kev siv kev siv thiab kev ntsuas kev sib tw thiab cov kev xav tau ntawm cov haujlwm tshwj xeeb tau muaj txiaj ntsig zoo. Yog li ntawd, kev faib ua feem ntawm kev thov dej siab-ua kom cov neeg sawv cev uas muaj peev xwm ua tiav "kev ua kom nruj" kev ua kom zoo "yuav tsum nce ntxiv.
JuFu Tshuaj Kho Mob Lub Tuam Txhab Ua Lag Luam tsis ua lag luam tshwj xeeb dua li lub lag luam tseem ceeb ntawm cov khoom lag luam hauv qab uas txawv ntawm nws cov neeg sib tw. Nyob rau hauv lub neej yav tom ntej, nws yuav muaj peev xwm rov qab ua tiav ntawm kev ua tiav superplasticizer, thiab chaw ua lag luam qab nthab ntau dua li ntawm superplastizers.
