Zochepetsera Madzi a Polycarboxylate Superplasticizer Zopangira Simenti
1. Super plasticizers ndi ma surfactants a hydrodynamic (zothandizira zogwira ntchito pamwamba) kuti zigwire ntchito bwino kwambiri pa chiŵerengero chotsika cha w/c mwa kuchepetsa kukangana pakati pa tirigu.
2. Ma Superplasticizer, omwe amadziwikanso kuti ma high range water reducers, ndi zowonjezera zomwe zimagwiritsidwa ntchito popanga konkriti yolimba kwambiri kapena kuyika konkriti yodzikakamiza yokha. Ma plasticizer ndi mankhwala omwe amalola kupanga konkriti yokhala ndi madzi ochepera pafupifupi 15%.
3. PC seris ndi polymer yapamwamba ya Poly carboxylate yomwe ili ndi mphamvu yogawanitsa madzi ndipo imasonyeza kulekanitsa madzi ndi kutuluka magazi, imawonjezeredwa popanga konkriti yogwira ntchito bwino komanso kuphatikiza ndi simenti, aggregate, ndi kusakaniza.

Sulphonated Melamine Formaldehyde (SMF) Superplasticizer ya Konkire Admixtures
1. Sulphonated Melamine Formaldehyde (SMF) imatchedwanso Sulfonated Melamine Formaldehyde, Sulphonated Melamine Formaldehyde Condensate, Sodium Melamine Formaldehyde. Ndi mtundu wina wa superplasticizer kupatula Sulphonated Naphthalene Formaldehyde ndi Polycarboxylate superplasticizer.
2. Super plasticizers ndi ma hydrodynamic surfactants (zothandizira zogwira ntchito pamwamba) kuti zigwire ntchito bwino kwambiri pa chiŵerengero chochepetsedwa cha w/c mwa kuchepetsa kukangana pakati pa tirigu.
3. Monga zosakaniza zochepetsera madzi, Sulfonated melamine formaldehyde (SMF) ndi polima yomwe imagwiritsidwa ntchito mu simenti ndi mapangidwe okhala ndi pulasitala kuti ichepetse kuchuluka kwa madzi, pomwe ikuwonjezera kusinthasintha ndi kugwira ntchito kwa kusakaniza. Mu konkriti, kuwonjezera kwa SMF mu kapangidwe koyenera kosakaniza kumapangitsa kuti pakhale porosity yochepa, mphamvu yayikulu yamakina, komanso kukana bwino malo ozungulira.

Sodium Naphthalene Sulfonate Formaldehyde FDN (Na2SO4 ≤5%) ya Konkriti Yosakaniza
1. Sodium naphthalene sulfonate formaldehyde FDN imatchedwanso naphthalene based superplasticizer, poly naphthalene sulfonate, sulfonated naphthalene formaldehyde. Maonekedwe ake ndi ufa wofiirira wopepuka. SNF superplasticizer imapangidwa ndi naphthalene, sulfuric acid, formaldehyde ndi madzi oyambira, ndipo imakumana ndi zochitika zosiyanasiyana monga sulfonation, hydrolysis, condensation ndi neutralization, kenako nkuumitsa kukhala ufa.
2. Naphthalene sulfonate formaldehyde nthawi zambiri imatchedwa superplasticizer ya konkriti, kotero ndiyoyenera kwambiri kukonza konkriti yamphamvu kwambiri, konkriti yokonzedwa ndi nthunzi, konkriti yamadzimadzi, konkriti yosalowa madzi, konkriti yosalowa madzi, konkriti yopangidwa ndi pulasitiki, zitsulo zomangira ndi konkriti yolimbikitsidwa. Kuphatikiza apo, sodium naphthalene sulfonate formaldehyde ingagwiritsidwenso ntchito ngati chosungunula m'mafakitale a zikopa, nsalu ndi utoto, ndi zina zotero. Monga wopanga waluso wa naphthalene superplasticizer ku China, Longou nthawi zonse amapereka ufa wa SNF wapamwamba kwambiri komanso mitengo ya fakitale kwa makasitomala onse.
