Cov ntsiab lus
OBC-31S yog cov roj polymer zoo cement kua dej poob additive.Nws yog copolymerized nrog AMPS, uas muaj kev tiv thaiv zoo rau kub thiab ntsev, raws li lub ntsiab monomer, ua ke nrog rau lwm cov ntsev-hlub monomers.Cov molecule muaj ntau ntawm -CONH2, -SO3H, -COOH thiab lwm cov pab pawg muaj zog adsorption, uas ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv ntsev, kub tsis kam, dej dawb adsorption, thiab txo cov kua dej.
OBC-31S muaj ntau yam zoo, tuaj yeem siv ntau yam ntawm cov cement slurry systems, thiab muaj kev sib raug zoo nrog lwm cov khoom ntxiv.
OBC-31S muaj cov ntawv thov dav dav, qhov kub siab tiv thaiv mus txog 180 ℃, zoo fluidity thiab ruaj khov ntawm cov cement slurry system, tsis muaj kua dawb, tsis muaj retardation, thiab kev loj hlob sai.
OBC-31S yog tsim rau cov dej tshiab / dej ntsev slurry sib tov.
