Kugwiritsa Ntchito Kwambiri Kuchepetsa Madzi Kufunsira
1. Kusintha kwa Mapangidwe a Maselo
Makina ochepetsera madzi a polycarboxylate okhala ndi unyolo wam'mbali wa ≥1.2 pa nm² amasankhidwa. Zotsatira zake zolepheretsa zimatha kuchepetsa kuwonongeka kwa adsorption wosanjikiza chifukwa cha kutentha kwambiri. Mukawonjezeredwa ndi 30% yosakaniza phulusa la ntchentche, kuchepetsa madzi kumatha kufika 35% -40%, ndi kutayika kwa ola limodzi osachepera 10%. Chotsitsa cham'mbali cha polycarboxylate chochepetsera madzi cham'mbalichi chimapanga mawonekedwe owoneka bwino pamwamba pa tinthu tating'ono ta simenti, zomwe zimapangitsa kuti tinthu tating'ono ta simenti tikhalebe mobalalika ngakhale m'malo otentha kwambiri. Kuphatikiza apo, kuwonjezera phulusa la ntchentche sikungochepetsa kugwiritsa ntchito simenti ndikuchepetsa kutentha kwa hydration, komanso kumapangitsa kuti pakhale mgwirizano wochepetsera madzi, kupititsa patsogolo kugwira ntchito komanso kulimba kwa konkriti.

2. Slump-Preserving Synergistic TechnologyKuyambitsidwa kwa methyl allyl polyoxyethylene etha monomer kumapanga mawonekedwe a maukonde amitundu itatu. M'malo ofananirako pa 50 ° C, kuphatikiza ndi gawo lobwezeretsa, kukulitsa konkire kumatha kusungidwa pamwamba pa 650mm kwa mphindi 120, kukwaniritsa zofunikira za kupopera kwa nyumba zapamwamba kwambiri. Kumayambiriro kwa methyl allyl polyoxyethylene etha monomers kumasintha kapangidwe ka maselo a polycarboxylate superplasticizer, kupanga mawonekedwe atatu azithunzithunzi zolumikizirana zomwe zimakulitsa luso lake lophatikiza ndi kufalitsa tinthu tating'ono ta simenti. M'malo otentha kwambiri, mawonekedwewa amatsutsana bwino ndi kusokonezedwa ndi zinthu za simenti za hydration, kusunga madzi ndi kutsika kwa konkire. Ikagwiritsidwa ntchito molumikizana ndi zinthu zobwezeretsanso, imatha kuchedwetsa simenti yothira madzi ndikusunga kutsika, kukwaniritsa zofunikira pakumanga konkriti wowoneka bwino, monga kupopera kokwera kwambiri.
