Concrete Superplasticizer – Polycarboxylate Superplasticizers

Timagwiritsa ntchito zosakaniza za mankhwala pokonzekera konkire pamodzi ndi zophatikizira ndi madzi kuti tisinthe zinthu zosiyanasiyana za konkire monga kuwonjezera kugwira ntchito., kuchepetsa kuchepa ndi dzimbiri, lowetsani tinthu tating'ono ta mpweya mu konkire, kufulumizitsa kapena kuchedwetsa kuuma ndi zina zambiri. Zosakaniza izi zimawonjezedwa pang'ono ndipo zimatha kupanga zomanga kukhala zotsika mtengo komanso zosavuta kumaliza.

Ma superplasticizer a konkriti omwe amagwiritsidwa ntchito masiku ano ndi polycarboxylate (PCE) pogwiritsa ntchito kuchepetsa madzi. PCE ndi yosakanikirana kwambiri ndipo akatswiri a zamankhwala akupitirizabe kugwiritsa ntchito polima kuti apereke luso lapadera kusakaniza konkire..

Mwambiri, Ma PCE amatha kuwonjezeredwa ku konkire yotsika ya w / c yokhala ndi nthawi yayifupi yosakanikirana ndikulola kusungika kwanthawi yayitali.. Mbali imeneyi imawapangitsa kukhala abwino kwa okonzeka-kusakaniza konkire ntchito kumene konkire khalidwe, makamaka kusunga kugwa ndikofunikira.

Ubwino wina wa ma PCE ndikuti amatha kugwiritsidwa ntchito ndi phulusa la ntchentche ndi zina zolowa m'malo mwa simenti. Izi ndizothandiza kwambiri m'madera omwe nkhawa zachilengedwe ndi mtengo wake zimadetsa nkhawa chifukwa zimalola kuti zinthu zambiri zobwezeredwa zigwiritsidwe ntchito popanda kupereka mphamvu kapena kutha ntchito.. Amaperekanso zabwino zina zogwirira ntchito monga kukulitsa mphamvu zoyambirira, kuchepetsa permeability ndi kukana bwino kwa ayoni kloridi ndi alkali.
