Cellulose ether imakhudza mpweya wamatope ndi simenti hydration

Ma cellulose ether amagwiritsidwa ntchito ngati chowonjezera mumatope ndi konkriti kuti apititse patsogolo zinthu zawo. Mukawonjezeredwa ku matope osakaniza, cellulose ether imatha kusokoneza mpweya ndi madzi a simenti.

Cellulose ether ndi polima yosungunuka m'madzi yomwe imakhala ndi mphamvu yosunga madzi kwambiri. Izi zikutanthauza kuti imatha kugwira mamolekyu amadzi ndikuwaletsa kuti asatuluke, zomwe zimathandiza kuti chisakanizo chamatopecho chizigwira ntchito kwa nthawi yayitali. Chotsatira chake, mpweya mumatope ukhoza kukonzedwa bwino, monga cellulose ether imathandiza kuchepetsa mpweya umene umatayika panthawi yosakaniza ndi kuyendetsa.

Kuphatikiza apo, ether ya cellulose imathanso kukhudza hydration ya simenti mu osakaniza amatope. Cement hydration ndi momwe zimachitikira pakati pa madzi ndi simenti, zomwe zimapangitsa kupanga konkire yolimba. Ma cellulose ether amatha kukhala ngati cholepheretsa, chomwe chimachepetsa kuchuluka kwa simenti. Izi zingakhale zopindulitsa muzochitika zina, monga pogwira ntchito ndi kutentha kapena kowuma, kumene kuyika kwamatope mofulumira kungayambitse ming'alu ndi zolakwika zina.

Ponseponse, kuwonjezeredwa kwa cellulose ether kumatope kumatha kuwongolera magwiridwe antchito ake, mpweya wake, ndi mphamvu za simenti. Ndikofunika kuzindikira kuti zotsatira zenizeni za cellulose ether pamatope zidzadalira mtundu ndi mlingo wa zowonjezera zomwe zimagwiritsidwa ntchito, komanso zinthu zenizeni za simenti ndi zigawo zina mu osakaniza.
