Cov ntsiab lus
OBC-30S yog cov roj polymer zoo cement kua dej poob additive.Nws yog copolymerized nrog AMPS / AM, uas muaj kev tiv thaiv zoo rau qhov kub thiab txias, raws li lub ntsiab monomer, ua ke nrog lwm cov ntsev-tso rau 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-30S muaj cov ntawv thov dav dav, qhov kub siab tiv thaiv mus txog 150 ° C, zoo fluidity thiab ruaj khov ntawm cov cement slurry system, tsis muaj kua dawb, tsis muaj retardation, thiab kev loj hlob sai.
OBC-30S yog haum rau configuring ntau seawater cement slurry systems thiab muaj zoo compatibility nrog rau lwm yam additives.
OBC-30S muaj zog dispersibility nyob rau hauv cov cement slurry, thiab tshwj xeeb tshaj yog haum rau kev teeb tsa ntawm cov cement slurry systems nrog cov ntsiab lus siab hauv cov dej tshiab los yog cov khoom siv zoo heev.
