Zotsatira za Cellulose Ether pa Gypsum ndi Cementitious Mortar

Ma cellulose ether amagwiritsidwa ntchito kwambiri kuti apititse patsogolo ntchito zomangira ma hydraulic, monga gypsum ndi simenti. Mu matope opangidwa ndi gypsum ndi simenti, imathandizira kusunga madzi, imatalikitsa kuwongolera ndi nthawi yotseguka, komanso imachepetsa kugwa.

1. Kusunga madzi

Cellulose ether imalepheretsa chinyezi kulowa khoma. Madzi okwanira amakhala mumatope, kotero kuti gypsum ndi simenti zikhale ndi nthawi yotalikirapo madzi. Kusungidwa kwa madzi kumagwirizana mwachindunji ndi kukhuthala kwa cellulose ether solution mumatope. Kuchuluka kwa mamasukidwe amphamvu, kumapangitsa kuti madzi asungidwe bwino. Chinyezi chikachuluka, kusunga madzi kumachepa. Chifukwa pa mlingo womwewo wa mankhwala a cellulose ether, kuwonjezeka kwa madzi kumatanthauza kuchepa kwa mamasukidwe akayendedwe. Kuwonjezeka kwa kusungidwa kwa madzi kudzawonjezera nthawi yochizira ya matope omwe akumangidwa.

2. Kuchepetsa mamasukidwe akayendedwe ndi kusintha workability

Kutsika kwa mamasukidwe a cellulose ether omwe amagwiritsidwa ntchito, kumachepetsa kukhuthala kwa matope ndipo motero kumagwira ntchito bwino. Komabe, low viscosity cellulose ether ali ndi mlingo wapamwamba chifukwa cha kuchepa kwa madzi.

3. Anti-sagging

Mtondo wabwino wosasunthika umatanthawuza kuti matope omwe amagwiritsidwa ntchito mumagulu okhuthala alibe chiopsezo chogwa kapena kutsika pansi. Kukana kwa Sag kumatha kusinthidwa ndi cellulose. Ma cellulose ether amatha kupereka kukana kwamatope kwabwinoko.

4. Zomwe zili mkati

Kuchuluka kwa kuwira kwa mpweya kumabweretsa kukolola kwamatope komanso kugwira ntchito bwino, kumachepetsa kupangika kwa ming'alu. Zimachepetsanso kuchuluka kwa mphamvu, zomwe zimapangitsa kuti pakhale zochitika za "liquefaction". Kuphulika kwa mpweya nthawi zambiri kumadalira nthawi yogwedeza.
