Polycarboxylate Superplasticizeryog suav tias yog qhov kev ua tau zoo admixture. Cov neeg ib txwm cia siab tias yuav muaj kev nyab xeeb dua, yooj yim dua, thiab muaj ntau dua yoog raws li kev tso cai nyob rau hauv cov ntawv thov, tab sis qhov xwm txheej tiag tiag tsis yog. Tau ntsib teeb meem sib txawv. Yog li, dab tsi yog qhov kev ceev faj rau kev sivPolycarboxylic Acidmmixtures?
1. Polycarboxylate Superplasticizerxav tau tswj hwm cov dej uas tsim nyog. Ntawm ib sab tes, txhawm rau kom ntseeg tau tias cov kav dej-cov muaj sib piv, ntawm qhov tod tes, vim tiasPolycarboxylate Superplasticizeryog rhiab heev rau kev siv dej. Cov ntsuas ntsuas uas feem ntau cuam tshuam cov kev ua tau zoo ntawm cov pob zeb ua ke suav nrog cov hmoov sib xyaw, cohesion thiab dej khaws cia. VimPolycarboxylate Superplasticizeryog rhiab heev rau kev siv dej, qee zaum kev noj dej tsuas yog nce los ntawm 1kg ~ 3kg thaum lub sijhawm sim thiab cov txheej txheem ntau lawm. Los ntshav, piles ntawm cov pob zeb loj, thawb hauv qab los ntawm daim lev, thiab tsis tuaj yeem lav cov kev sib xyaw ntawm cov pob zeb sib xyaw. Yog li ntawd, kev siv dej tsis sib haum yuav tsum ua nruj me ntsis thaum muaj ntau yam.
2. Tswj cov ntsiab lus ntawmPolycarboxylic AcidCov. Cov ntsiab lus tsis txaus ntawm qhob yog manifested los ntawm kev poob nrawm nrawm, ploj, thiab fluidity tsis zoo; Ntau dhau lawm yuav ua rau los ntshav, cais, thiab hauv qab tsaj. Nws yog ib qho tsim nyog los ua ntau yam kev ntsuas los txiav txim siab qhov zoo tshaj plaws haum ntawm kev noj dej thiabPolycarboxylate Superplasticizercov ntsiab lus. Point, uas yog, kev noj dej zoo tshaj plaws thiab admixture noj.
3. Nws yog nruj me ntsis txwv tsis pub sib xyaw naphthalene admixtures. Raws li cov phiaj xwm sib txawv, feem ntau pob zeb ua kom sib xyaw cov nroj tsuag yuav tsum tau siv naphthalene admixtures thaum sivPCECov. Yog tias muaj kev mob daim ntawv tso cai, nws yog qhov zoo tshaj plaws los siv hauv cov chaw nres tsheb sib txawv. Yog tias tib chav tsev muaj ob qho tib sipolycarboxylate tus superplasticizerThiab naphthalene, lub nra hnyav, pipeline thiab tov khoom rau admixture yuav tsum tau huv si thaum xaiv lwm yam, thiab cov vaj tse nqa khoom yuav tsum tau ntxuav. Huv si thiab reload. YogPolycarboxylic AcidThiab naphthalene-raws admixtures tau sib xyaw thiab siv, ob lub admixtures yuav ua rau cov pob zeb ua kom nruj "sai sai", ua rau tag nrho cov tsheb kom raug kaw.
4. Tswv kev soj ntsuam ntawmPolycarboxylate Superplasticizeradmixtures. Thaum kuaj xyuas cov qauv admixtures, coj cov qauv los ntawm cov ntaub ntawv raw uas twb muaj lawm uas yuav siv, thiab sim cov pob zeb raws li cov kev xav tau ntawm txoj haujlwm. Yog tias muaj teeb meem tshwm sim, thov kom sai nug cov neeg ua haujlwm ntawm admixture ua kom haum.
Hauv ntej, qhobPolycarboxylic acid adm machpshatureyog hom khoom tshiab. Piv nrog tsoos dej ib txwm muaj, nws tsis tsuas yog muaj cov dej tsawg dua, cov tshuaj txo dej siab, qis alkalinity, thiab qhov tseeb pom tseeb hauv qab nyhuv. Txhim kho cov kav dej ruaj khov, thiab cov txheej txheem ntau lawm ntawmPolycarboxylate SuperplasticizerDej reducer yog huv thiab muaj kuab paug-dawb. Nws yog hom tshiab ntawm ntsuab thiab ib puag ncig tus phooj ywg siab-ua tau zoo dej reducer.
