Cov molecules ntawm covpolycarboxylate dej txo tus neeg sawv cevyog tsim los ntawm "molecular tsim" nrog ib tug "comb" los yog "dendritic" qauv, thiab muaj ntau ceg ntawm ib tug tej yam ntev thiab rigidity txuas mus rau lub ntsiab saw ntawm lub molecule (Side saw). Kuj tseem muaj cov sulfonates lossis lwm pab pawg ntawm cov saw tseem ceeb uas tuaj yeem them cov khoom siv cement, uas tuaj yeem ua raws li cov dej txo qis. Qhov tseem ceeb tshaj, thaum cov saw tseem ceeb yog adsorbed rau saum npoo ntawm cov cement hais, cov ceg ntoo yuav cuam tshuam nrog lwm cov khoom. Cov saw saw caj dab tsim ib qho kev sib tshuam ntawm peb sab, uas tiv thaiv cov khoom los ntawm kev sib cuag, kom ua tiav cov txiaj ntsig ntawm kev tawg (xws li dej txo). Qhov no steric hindrance tsis muaj zog los ntawm lub sij hawm ncua, yog li ntawd, cov nyhuv dispersion ntawm lubPob zeb thiab mortar Superplasticizer Polycarboxylate Superplasticizer (PCE Hmoov)yog ruaj dua.

Kev tsim kho chemical Water reducer Polycarboxylate Superplasticier (PCE Liquid) Kev ua haujlwm siab dej reducer yog lub cim thib peb ntawm kev ua haujlwm siab dej reducer tsim tom qab cov dej reducer sawv cev los ntawm cov ntoo calcium thiab cov dej ua haujlwm siab uas sawv cev los ntawm naphthalene series. Nws yog tam sim no tshaj plaws nyob rau hauv lub ntiaj teb no. , Ib qho superplasticizer nrog cov ntsiab lus tshawb fawb thiab thev naus laus zis siab tshaj plaws, qhov kev thov zoo tshaj plaws thiab kev ua tau zoo tshaj plaws.

Polycarboxylate Superplasticizer PCE Liquid Slump Retentionmuaj ib tug loj feem ntawm cov khoom xyaw nquag thiab ib tug concentrated molecular hnyav ntau yam. Yog li ntawd, piv nrog lwm cov dej txo cov neeg ua haujlwm,polycarboxylic acid dej txo tus neeg sawv cevTsis tsuas yog muaj qhov txo qis dej ntau dua, tab sis kuj tswj kev poob qis, thiab qhov ntau npaum li cas me dua. . Cov pob zeb npaj nrog polycarboxylic acid-raws li kev ua haujlwm siab dej-txo tus neeg saib xyuas yuav tsis muaj kev sib cais thiab los ntshav txawm tias muaj kev poob qis, thiab cov tsos thiab xim ntawm cov pob zeb yuav zoo ib yam. Nws yog qhov muaj txiaj ntsig zoo rau kev npaj cov pob zeb ua kom muaj dej ntws zoo, ua kom nws tus kheej-leveling pob zeb, nws tus kheej-compacting pob zeb, thiab cov pob zeb ncaj ncees. Thaum siv rau hauv kev npaj ntawm high-qib pob zeb, cov pob zeb muaj kev ua haujlwm zoo, kev sib koom ua ke zoo, thiab cov pob zeb sib xyaw yooj yim. Nws muaj kev sib raug zoo nrog ntau hom cement thiab admixtures, thiab daws cov teeb meem compatibility ntawm lwm hom dej-txo cov neeg ua hauj lwm thiab cov ntaub ntawv cementitious.
