Polycarboxylate superplasticizer ndi m'badwo wachitatu wa superplasticizer wochita bwino kwambiri wopangidwa pambuyo pa superplasticizer wamba yoimiridwa ndi calcium yamatabwa ndi superplasticizer yoyimiridwa ndi mndandanda wa naphthalene.

Polycarboxylate based superplasticizer pakadali pano ndiyothandiza kwambiri kuchepetsa madzi yokhala ndi zasayansi komanso ukadaulo wapamwamba kwambiri, chiyembekezo chogwiritsa ntchito bwino kwambiri, komanso magwiridwe antchito abwino kwambiri.PCE mankhwala amakhalanso mndandanda wa ochepetsera madzi omwe ali ndi ntchito zabwino kwambiri zomwe zimagwirizanitsa kuchepetsa madzi, kusungirako kugwa, kulimbikitsa, kutsutsa-kuchepa komanso kuteteza chilengedwe.Ikhoza kuthetsa kwathunthu kufooka kwa konkire yamphamvu kwambiri, yogwira ntchito kwambiri ndi ntchito ya viscosity yapamwamba komanso ntchito yomanga yomanga.

Ubwino wogwiritsa ntchito mu zosakaniza za konkriti ndi izi:

1) Kuwonjezeka kwakukulu kwamphamvu koyambirira

2) Kuchepetsa kwakukulu kwa kugwa kotayika

3) Kukhalitsa kwabwino kwambiri: Kuchepetsa kusweka, kutsika ndi kukwawa

4) Kuchepetsa madzi apamwamba: Kuchepetsa madzi kuposa 30% malinga ndi ntchito zosiyanasiyana

5) Zogulitsa zachilengedwe: Palibe kuipitsa panthawi yopanga

6) Kugwirizana kwabwino ndi mitundu yosiyanasiyana ya simenti

7) Kutsika kwa kloridi ndi zamchere, palibe dzimbiri pazitsulo zachitsulo

Ndi ma PCE ati omwe tikupereka pamsika wapakhomo ndi wakunja?
