Polycarboxylate Superplasticizer makamaka copolymerized ndi monomers unsaturated pansi zochita za intiators, ndi unyolo mbali ndi magulu yogwira kumezetsanidwa pa unyolo waukulu wa polima, kotero kuti ali ndi ntchito za dzuwa mkulu, kulamulira kugwa imfa ndi shrinkage kukana, osati kumakhudza coagulation ndi kuumitsa simenti. Polycarboxylic acid high-performance water reducer ndi yosiyana kwambiri ndi naphthalene sulfonate formaldehyde condensate NSF ndi melamine sulfonate formaldehyde condensate MSF water reducer. Zingapangitse konkire yamatope kukhala ndi madzi ambiri ngakhale pa mlingo wochepa, ndipo imakhala ndi kukhuthala kochepa komanso kusungirako ntchito zowonongeka pamtunda wochepa wa simenti. Zimayenderana bwino ndi simenti zosiyanasiyana ndipo ndizofunikira kwambiri pa konkriti yamphamvu kwambiri komanso yamadzimadzi.

Polycarboxylate Superplasticizer ndi m'badwo wachitatu wa makina ochepetsera madzi opangidwa ndi matabwa opangidwa ndi matabwa a calcium ndi naphthalene water reducer. Poyerekeza ndi chochepetsera madzi chachikhalidwe, ili ndi zabwino izi:

a. Mlingo wochepetsera madzi: Mlingo wochepetsera madzi wa polycarboxylic acid wochepetsetsa kwambiri wamadzi amatha kufikira 25-40%.

b. Kukula kwamphamvu kwamphamvu: kuchuluka kwamphamvu kwambiri, makamaka kukula kwamphamvu koyambirira.

c. Kusungirako bwino kwambiri: Kusungirako bwino kwambiri kumapangitsa kuti konkire iwonongeke nthawi yochepa.

d. Good homogeneity: Konkire yokonzedwayo imakhala ndi madzi abwino kwambiri, ndi yosavuta kuthira komanso yaying'ono, ndipo ndi yoyenera kudzipangira nokha komanso kudzipangira konkire.

e. Kuwongolera kwapang'onopang'ono: Mlingo wochepetsera madzi, kusungidwa kwa pulasitiki ndi magwiridwe antchito a mpweya wa mndandanda wa zochepetsera madzi zitha kusinthidwa posintha kulemera kwa ma polima, kutalika, kachulukidwe ndi mtundu wamagulu am'mbali.

f. Kusinthasintha kwakukulu: Ili ndi dispersibility yabwino komanso kusungidwa kwapulasitiki kwa silicon yoyera, silicon wamba, simenti ya slag silicate ndi zosakaniza zosiyanasiyana kuti apange konkire.

g. Kutsika kochepa: Kutha kupititsa patsogolo kukhazikika kwa konkire, ndipo 28d shrinkage ya naphthalene-based water reducer konkire imachepetsedwa ndi 20%, zomwe zimachepetsa bwino kuwonongeka kwa konkriti.

h. Zobiriwira komanso zachilengedwe: zopanda poizoni, zosawononga, komanso zilibe formaldehyde ndi zinthu zina zoyipa.
