Mtondo wodziyimira pawokha ukhoza kudalira kulemera kwake kuti upange maziko athyathyathya, osalala, komanso olimba pagawo loyikapo kapena kulumikiza zida zina, ndipo amathanso kumanga zazikulu komanso zogwira mtima. Chifukwa chake, kuchuluka kwamadzimadzi ndi gawo lofunikira kwambiri pakudziwongolera matope; Kuonjezera apo, iyeneranso kukhala ndi mlingo wina wa kusungirako madzi ndi mphamvu zomangirira, popanda kuchitika kwa kulekanitsa madzi, ndikukhala ndi makhalidwe otsekemera komanso kutentha kochepa. Nthawi zambiri, matope odziyimira pawokha amafunikira madzi abwino, koma madzi enieni a slurry simenti nthawi zambiri amakhala 10-12cm; Cellulose ether ndi chowonjezera chachikulu mumatope osakaniza okonzeka. Ngakhale kuti ndalama zomwe zimawonjezeredwa ndizochepa kwambiri, zimatha kusintha kwambiri ntchito yamatope. Ikhoza kupititsa patsogolo kusasinthasintha, kugwira ntchito, kugwirizanitsa ntchito, komanso kusunga madzi kwa matope. Zimagwira ntchito yofunika kwambiri m'munda wa matope osakanikirana.

1. Liquidity
Cellulose ether imakhudza kwambiri kusungidwa kwa madzi, kusasinthika, ndi kamangidwe ka matope odziyimira pawokha. Makamaka ngati matope odziyimira pawokha, kuthamanga ndi chimodzi mwazizindikiro zazikulu zodziwunikira momwe mukugwirira ntchito. Pamaziko owonetsetsa kuti matope apangidwe bwino, madzi amadzimadzi amatha kusinthidwa mwa kusintha mlingo wa cellulose ether. Komabe, mlingo wochulukirawu ukhoza kuchepetsa kusungunuka kwa matope, kotero mlingo wa cellulose ether uyenera kuyendetsedwa mosiyanasiyana.

2. Kusunga madzi
Kusungidwa kwamadzi kwa matope ndi chizindikiro chofunikira choyezera kukhazikika kwa zigawo zamkati zamatope osakanikirana a simenti. Kuti zinthu za gel zikhale zodzaza ndi madzi okwanira, kuchuluka kwa cellulose ether kumatha kusunga chinyezi mumatope kwa nthawi yayitali. Nthawi zambiri, kuchuluka kwa kasungidwe kamadzi ka slurry kumawonjezeka ndi kuchuluka kwa cellulose ether. Mphamvu yosungiramo madzi ya cellulose ether imatha kuletsa gawo lapansi kuti lisatenge madzi kwambiri kapena mwachangu kwambiri, ndikulepheretsa kutuluka kwa madzi, motero kuwonetsetsa kuti chilengedwe cha slurry chimapereka madzi okwanira a simenti. Komanso, mamasukidwe akayendedwe a cellulose ether kumathandizanso kwambiri posungira madzi matope. Kuchuluka kwa mamasukidwe amphamvu, kumapangitsa kuti madzi asungidwe bwino. Ma cellulose ether okhala ndi kukhuthala konse kwa 400mpa. s amagwiritsidwa ntchito popanga matope odzipangira okha, omwe amatha kuwongolera magwiridwe antchito komanso kuphatikizika kwa matope.
