Cov ntsiab lus
OBC-43S yog cov roj polymer zoo cement kua dej poob additive.Nws yog copolymerized nrog AMPS / NN, uas muaj kev tiv thaiv zoo rau kub thiab ntsev, raws li lub ntsiab monomer, ua ke nrog lwm cov ntsev-tiv taus monomers.Cov khoom lag luam qhia cov pab pawg uas tsis yooj yim hydrolyzed, qhov kub thiab txias tsis kam yog pom tseeb txhim kho, thiab cov molecule muaj ntau pawg muaj zog adsorption xws li -CONH2, -SO3H, -COOH, uas ua lub luag haujlwm tseem ceeb hauv qhov kub thiab txias, adsorption. dej dawb, thiab poob dej.
OBC-43S muaj ntau yam zoo, tuaj yeem siv rau ntau yam cement slurry systems, thiab muaj kev sib raug zoo nrog lwm cov khoom ntxiv.
OBC-43S muaj qhov siab qis qis qis viscosity, uas tuaj yeem txhim kho qhov kev ncua kev ruaj ntseg ntawm cov cement slurry system, thaum tuav lub fluidity ntawm slurry, tiv thaiv sedimentation, thiab muaj roj zoo channeling kuj.Lub viscosity ntawm qis shear tus nqi qis dua OBC-33S.
OBC-43S muaj cov ntawv thov dav dav, qhov kub siab tiv thaiv mus txog 230 ℃, zoo fluidity thiab ruaj khov ntawm cov cement slurry system, tsawg dua cov kua dawb, tsis muaj retardation, thiab kev loj hlob sai ntawm lub zog thaum ntxov ntawm qhov kub thiab txias.
OBC-43S yog tsim rau cov dej tshiab / dej ntsev slurry sib tov.
