Tsab ntawv xov xwm no qhia txog ib txoj hauv kev npaj cov yas yas rau ntub-sib tov mortar, uas muaj feem xyuam rau kev ua haujlwm ntawm cov khoom ntub-siv mortar admixtures. Tom qab ntawd ntxiv cov khoom A (hydroxyethyl acrylate, mercaptopropionic acid thiab cov dej mos sib xyaw) thiab cov khoom B (Tau los ntawm mixingsodium formaldehyde sulfoxylate / Sodium bisulfoxylate formaldehyde / rongalite nrog dej mos), 16h maturation cov tshuaj tiv thaiv ntawm 2528 ℃, thiab tom qab ntawd ntxiv cov dej mos kom dilute cov dej. cov khoom kom txog rau thaum cov ntsiab lus theoretical ntawm 40%, uas yog, kom tau cov plasticizer.

Lub plasticizer tau txais los ntawm txoj kev npaj no muaj lub sijhawm teem sijhawm ntev dua, zoo dua qhov tsis sib xws thiab cov dej tuav tau zoo dua thaum siv rau cov khoom sib xyaw ntub dej, uas yooj yim dua rau kev tsim kho.
