Polycarboxylate Superplasticizer hmoov

Polycarboxylate superplasticizer hmoov

Nws yog lub cim thib peb ntawm cov dej ua kom txo qis tus neeg sawv cev, nws qhov kev ua tau zoo tshaj plaws yog qhov zoo heev, ntsuab thiab tsis muaj kuab lom, nws yog cov khoom ua tau zoo thiab ib puag ncig-phooj ywg. Nws yog cov hmoov hloov pauv polycarboxylate superplasticizer ua los ntawm cov txheej txheem ziab kom qhuav. Lub fluidity ntawm cov hmoov yog zoo heev, thiab nws yog tshwj xeeb tshaj yog haum rau siv raws li ib tug dispersant nyob rau hauv hmoov cov ntaub ntawv uas yuav tsum tau muaj kev kawm siab. Hom dej txo tus neeg sawv cev no muaj qhov zoo dispersibility, siab dej txo tus nqi, thiab zoo adaptability rau txawv cements. Thaum siv hauv pob zeb thiab mortar, fluidity ntawm qhov sib tov yog zoo heev. Nyob rau tib lub sijhawm, nws tseem tuaj yeem siv rau hauv cov haujlwm xws li cov plag tsev tus kheej thiab cov ntaub ntawv grouting.
