Puas yog cov polycarboxylic acid dej tsim tawm thiab cov kab hluav taws xob tiv thaiv ua rau qhov nce ntawm pob zeb viscosity? Thaum dej txo tus neeg sawv cev ntxiv rau hauv cov pob zeb ua kom tshiab los txo cov dej noj ntawm cov pob zeb ua kom tsis muaj dej ntxiv txo tus neeg sawv cev nrog tib qhov poob qis, viscosity ntawm kev sib tov yuav tau nce ntxiv, lub sijhawm luv luv yuav tshwm sim flocculation, tab sis me ntsis kev co tuaj yeem pom qhov ua tau zoo.
Molecular qauv ntawm poly (carboxylic acid tuaj yeem qhia kom muaj qhov chaw loj steric kev ua kom tsis haum ntawm cov hlua ntev ntev, tuaj yeem ua tus choj ntawm cov nplais pob zeb, feem ntau thaum pib ntawm cov pob zeb ua kev sib xyaw nthuav tawm tsis loj, zoo li nplaum dua, tab sis dhau sijhawm, cov qauv ntawm tus choj carboxylate tus qauv rhuav tshem hauv cov roj av ua kua dej, ua kev cuam tshuam ntawm polymer cov pa roj carbon monoxide, adsorption los ntawm cov cement, tom qab ib lub sijhawm txawm tias nrog cov khoom siv dej tsis sib haum, sab saw qauv yuav tsis raug rhuav tshem, tuaj yeem siv sijhawm ntev los tswj hwm nws txoj kev tawg.
Nyob rau hauv luv luv, ntxiv polycarboxylic acid nyob rau hauv lub xeev ntawm tib qhov kev poob ntawm cov pob zeb ci viscosity yog nce, tab sis overmixing yuav xau dej, yog li lub tsev tus Tswv tau hais nrog kev nce ntxiv ntau npaum ntawm cov cement slurry viscosity, yog ib qho-nyob ib sab.In tsim nyog qhov ntau npaum, cov qhob yuav ua rau thicker thaum cov tshuaj ntau dua, tab sis cov fluidity yuav dhau los ua zoo dua.
