Cov teeb meem uas muaj nyob rau hauv kev siv tswv yim ntawm Polycarboxylate Water Reducer hauv pob zeb Engineering
1. Cov txiaj ntsig ntawm kev siv dej ntawm kev ua haujlwm ntawm polycarboxylate pob zeb sib tov
Kev cuam tshuam ntawm kev siv dej yog pom tseeb heev. Hauv kev siv tiag tiag ntawm kev ua vaj tse pob zeb, qee zaum yog tias cov dej haus tau nce los ntawm 1-3kg / m3, cov pob zeb yuav muaj qhov tshwm sim los ntshav loj, uas yuav ua rau muaj qhov tsis xws luag xws li pitting, sanding, thiab qhov ntawm qhov chaw. Uniformity thiab kev tsim kho zoo tsis tuaj yeem lav, yog li txo lub zog thiab kav ntev ntawm cov qauv pob zeb.
2. Polycarboxylate pob zeb yog nquag delamination thiab cais
Feem ntau, ntxiv polycarboxylate superplasticizer rau pob zeb yuav txo tau cov viscosity ntawm slurry. Nyob rau tib lub sijhawm, txawm tias qhov ntau npaum li cas thiab dej noj ntawm polycarboxylate superplasticizer yog qhov zoo tshaj plaws, thiab yuav tsis muaj los ntshav, cov pob zeb ua rau stratification thiab segregation, uas yog feem ntau tshwm sim hauv coarse aggregate thiab mortar. , Lub net pulp yog sib cais thiab dab dej ntau ntau. Hom kev sib xyaw ua ke no tsis muaj kev vibration hauv pob zeb engineering pouring, thiab qhov tshwm sim ntawm txheej txheej thiab cais tawm kuj pom tseeb heev.
3. Kev sib raug zoo tsis yog qhov zoo tagnrho
Naphthalene series, aliphatic series, lignin sulfonate, amino sulfonate thiab lwm yam tshuaj tua kab mob tuaj yeem muab sib xyaw rau hauv ib qho kev faib ua feem, thiaj li ua tau raws li ntau yam kev npaj ua vaj tse. Cov tsoos dej reducers Cov neeg sawv cev tuaj yeem tsis tsuas yog yaj zoo hauv dej, tab sis kuj tuaj yeem ua tiav cov nyhuv superimposed thaum siv ua ke. Polycarboxylate superplasticizer muaj cov kev txwv loj, nws tsuas yog siv tau ua ke nrog cov tsoos superplasticizer lignosulfonate, thiab tsis zoo sib xws nrog lwm cov tshuaj superplasticizers. Yog hais tias nws yog siv nyob rau hauv ua ke nrog nrog rau lwm yam hom ntawm cov tsoos dej txo cov neeg ua hauj, tsis tsuas yog nws nyuaj rau ua tau superimposed los, tab sis lub fluidity ntawm cov pob zeb yuav tsis zoo, cov dej haus yuav nce heev, qhov poob ntawm slump yuav loj heev. , thiab cov pob zeb yuav qhuav thiab nyuaj rau unload. , lub zog thiab durability ntawm pob zeb yuav raug cuam tshuam loj heev.
