3. Makina a zochita za superplaciliction

Njira yamadzi yochepetsera mankhwala kuti isinthe madzi osakaniza konkriti makamaka imaphatikizapo kubalalitsa mphamvu ndi kuthira mafuta. Madzi ochepetsa madzi ndi owonjezera, kumapeto kwake kumatha kusungunuka mosavuta m'madzi - gulu la hydrophilic, ndipo mbali inayo ndi yopanda mphamvu m'madzi - hydrophobic gulu.

a. Kubalalika: Pambuyo pa simenti itasakanikirana ndi madzi, chifukwa cha kukopeka kwa ma cementine tating'ono, simenti slurry kumapangitsa kuti 10% ya madzi osakanikirana itakulungidwa mu tinthu tating'onoting'ono Kuyenda ndi kupangira mafuta. Zotsatira zake zimakhudza madzimadzi osakaniza konkriti. Pamene madzi kuchepetsa mankhwalawo amawonjezeredwa, chifukwa madzi kuchepetsa mamolekyulumini azithunzi amatha kukhala pachibwenzi pamtunda wa simementi Imalimbikitsa kubalalitsidwa kwa simenti tikulu ndi kuwonongedwa kwa malo osungirako malo. , kumasula gawo lokutidwa la madzi ndi kutenga nawo mbali poyenda, potero kuwonjezera madzimadzi a konkriti.

b. Mafuta: Gulu la Hydrophilic ku Superplucise lomwe lili Polar, motero filimu ya Adsorption ya SuperPuccizer Padera tinthu tating'onoting'ono ndi mamolekyulu, ndipo filimu yamadziyi imachepetsa bwino Kutsutsa pakati pa denga la simenti, potero kukonza madzima simenti.

Zotsatira za kuchepa kwa madzi pa konkreti, etc.:

a. Khazikitsani nthawi. Superplariciters nthawi zambiri ilibe kubwezera, ndipo ingakweze ngakhale hydration ndi kuuma simenti. Superputericcizercizercizercizercise yobwezeretsedwa ndi compucite ya superplasticiter. Pakakhala zovuta zina, kuti achedwetse mankhwala a simenti ndikuchepetsa kutaya kwa slump, obwezeretsanso amawonjezeredwa kumadzi.

b. Zokhudzana ndi mafuta. Pakadali pano, pogwiritsa ntchito polycaxylate wamadzi ofala amakhala ndi mpweya wina, ndipo mpweya womwe uli ndi konkriti suyenera kukhala wokwera kwambiri, apo ayi mphamvu yotsirizika idzachepetsedwa kwambiri.

c. Kusungidwa kwamadzi.

Superplasticizers sizimathandiza kwambiri kuchepetsa magazi a konkriti, ndipo amathanso magaziwo. Kutulutsa kwa simenti kumawonjezeka pomwe Mlingo wake ndi wowonjezera.
