1. Muaj tshwm sim teeb meem ntawm kev yoog raws nrog cov cement. Rau qee qhov cement, dej txo tus nqi tsawg thiab qhov poob qis yog qhov loj dua.Qhov ntxiv, xis mas zoo nkauj thiab lub sijhawm khaws cia tseem yuav cuam tshuam rau kev siv kua qaub - acid superplasticizer.
2. Nws muaj kev cuam tshuam cov kev hloov ntawm raw cov ntaub ntawv. Thaum qhov zoo ntawm cov xuab zeb, pob zeb cov ntaub ntawv thiab admixtures xws li ya tshauv thiab hmoov av hmoov hloov pauv hloov ntau, nws yuav muaj qhov cuam tshuam rau kev ua tau zoo ntawm cov pob zeb ua uas muaj polycarboxylic acid superplasticizer.
3. Vim tias cov dej yuav txo qis hauv tsev, pob zeb pob zeb yog qhov tshwj xeeb rau kev noj haus dej.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tswj hwm qhov ntau ntawm cov tshuaj polycarboxylic acid superplasticizer thiab cov dej noj ntawm cov qhob.Yog li cov dhau mus, qhob yuav tshwm sim cais, los ntshav, ua kom tawv thiab roj uas muaj ntau yam tshwm sim uas tsis xav ua.
4. Nws tshwj xeeb tshaj yog cov av nkos cov ntsiab lus ntawm cov sib sau ua ke, thiab cov av nkos ntau dhau yuav txo qis kev ua haujlwm ntawm polycarboxylic acid superplasticizer.Yog li ntawd, qhov zoo ntawm kev sib xyaw yuav tsum nruj tswj hwm thaum siv polycarboxylic acid superplasticizer.The cov ntsiab lus ntawm polycarboxylic acid superplasticizer yuav tsum yog ntau zog thaum cov av nkos cov ntsiab lus ntawm cov ntau ntau zuj zus.
5. Polycarboxylic acid superplasticizer yuav tsum tsis txhob xyaw nrog naphthalene series superplasticizer. Thaum siv cov polycarboxylic acid superplasticizer, nws yog qhov yuav tsum tau yaug cov khoom tov thiab tov nrog naphthalene series superplasticizer, txwv tsis pub, polycarboxylic acid superplasticizer yuav poob nws cov dej-txo cov nyhuv.
6. Zam kev sib tiv tauj ntev nrog cov khoom siv hlau.Because polycarboxylic acid superplasticizer cov khoom lag luam feem ntau tshwm sim kua qaub, kev tiv thaiv ntev ntev nrog cov khoom lag luam hlau yuav tsim cov tshuaj tiv thaiv qeeb, thiab txawm ua rau nws cov xim tsaus, dub, uas ua rau cov khoom lag luam poob qis.Nws yog pom zoo kom siv polyethylene yas nruas lossis stainless hlau nruas cia, kom ntseeg tau tias kev ruaj khov ntawm nws kev ua haujlwm.
