(1) Tsim nyog tswj kev haus dej
Polycarboxylic acid superplasticizer rhiab heev rau kev siv dej, tshwj xeeb tshaj yog thaum siv cov superplasticizer nrog cov ntsiab lus siab tau siv. Hauv cov txheej txheem ntawm kev sib xyaw thiab tsim khoom, nws tau pom tias qee zaum thaum kev siv dej tau nce me ntsis los ntawm 1kg ~ 3kg, cov khoom sib xyaw ua ke yuav tshwm sim los ntshav loj, nthuav tawm pob zeb sib tsoo, cais cais thiab lwm yam. Yog li ntawd, hauv cov txheej txheem tsim khoom, ntawm ib sab, kev siv dej ib leeg yog tswj nruj me ntsis, thiab cov ntsiab lus dej ntawm cov xuab zeb thiab pob zeb raug ntsuas kom raug, cov xuab zeb ntxuav tshiab yuav tsum tau siv rau ib ntus kom txog thaum cov dej muaj ruaj khov. Ntawm qhov tod tes, polycarboxylic acid dej-txo tus neeg sawv cev nrog cov ntsiab lus tsis tau raug xaiv los txo qhov rhiab heev.
(2) Siv cov tshuaj polycarboxylic acid tsim nyog
Siv cov txheej txheem los ntawm kev ntsuas txhawm rau txiav txim siab qhov tsim nyog noj, ntau npaum li cas ntawm cov pob zeb ua rau lub peev xwm ua tsis tau zoo, poob qis, tsis muaj dej txaus, ntau npaum li cas, yooj yim ua rau muaj kev sib xyaw ua rau muaj ntshav loj, cais, nkag hauv qab. Ua ntej kev tsim khoom, nws yog qhov tsim nyog los ntsuas qhov ua tau zoo tshaj plaws ntawm kev siv cov dej ua ke thiab polycarboxylic acid superplasticizer ntau npaum li cas, uas yog, kev siv dej zoo tshaj plaws thiab kev sib xyaw ntau npaum li cas, thiab ua tib zoo saib xyuas tus tswv ntawm cov khoom siv hloov pauv ntawm polycarboxylic acid superplasticizer ntau npaum li cas. Cov ntaub ntawv raw siv hauv txoj haujlwm yuav tsum raug siv rau hauv qhov kev sim txhawm rau pab tswj kev tsim khoom, thiab qhov chaw tsim kho qhov chaw yuav tsum raug sim raws li qhov yuav tsum tau tsim thaum tsim nyog.
