Concrete Superplasticizer

konkriti superplasticizer ndi kuphatikiza kofunikira komwe kumagwiritsidwa ntchito popanga konkriti yogwira ntchito kwambiri. Zimathandizira kukonza magwiridwe antchito ndi mphamvu ya konkriti yogwira ntchito kwambiri molumikizana ndi fume la silika, kuwuluka phulusa, slag, kapena zina zowonjezera.

Superplasticizers (SP) ndi macromolecules sungunuka, zazikulu nthawi mazana kuposa mamolekyu amadzi. Amatchinjiriza ku C3A mu tinthu tating'ono ta simenti ndikutulutsa madzi otsekeka.

Mu kusakaniza konkire, superplasticizers izi anawonjezera pa mlingo otsika ndi munthu pazipita 2 peresenti ya madzi onse. The osakaniza ndiye osakaniza pa osachepera 3 mphindi ndi kubowola makina kapena 5 mphindi ndi chosakanizira matope.

Kuphatikiza kwa superplasticizers kumachepetsa kuchuluka kwa madzi mu zosakaniza za konkire popanda kuchepetsa mphamvu kapena kugwira ntchito kwa kusakaniza.. Zimenezi zingapulumutse ndalama zambiri pa zipangizo zomangira komanso nthawi.

Zimathandizanso kupewa tsankho muzosakaniza zophatikizana.

Vuto lodziwika bwino logwiritsa ntchito superplasticizers ndikuti amakonda kutaya mphamvu zawo mwachangu. Izi zitha kubweretsa zovuta pakuyika konkire chifukwa magalimoto obwera okonzeka amayenera kuyenda maulendo ataliatali pakati pa malo antchito..

Mavutowa angathetsedwe pogwiritsa ntchito chosiyana ndi chochepetsera madzi chapamwamba: viscosity kusintha admixtures (Chithunzi cha VMA). Ma VMA ndi osakaniza a ufa omwe amachepetsa kutsika kwa konkire ndikuthandizira kupewa tsankho mu konkire yokhazikika..

Mphamvu za konkriti zogwira ntchito kwambiri zomwe zili ndi SMF ndi SNF-type superplasticizers ndizokwera kuposa za konkriti zomwe zimapangidwira pakugwa komweko popanda kusakaniza., ngakhale madzi:chiŵerengero cha simenti ndi chofanana. Komabe, kuwonjezereka kwa mphamvu kumabwera makamaka chifukwa cha kuchepa kwa madzi omwe amadza chifukwa chogwiritsa ntchito zosakaniza izi..
