Mtondo wodziyimira pawokha ukhoza kudalira kulemera kwake kuti upange maziko athyathyathya, osalala komanso olimba pa gawo lapansi poyikapo kapena kumangiriza zida zina.Ikhozanso kumanga bwino m'dera lalikulu.Kuchuluka kwamadzimadzi ndi gawo lofunika kwambiri la matope odzipangira okha.;Kuonjezera apo, iyeneranso kukhala ndi kusungirako madzi ndi mphamvu zomangirira, osatulutsa tsankho la madzi, komanso kukhala ndi zizindikiro za kutentha kwa kutentha ndi kukwera kwa kutentha.
Kawirikawiri, matope odzipangira okha amafunikira madzi abwino.Cellulose etherndi chowonjezera chachikulu cha matope osakaniza okonzeka.Ngakhale kuti ndalama zowonjezera ndizochepa kwambiri, zimatha kusintha kwambiri ntchito ya matope.Iwo akhoza kusintha kugwirizana, ntchito ntchito, ndi katundu Adhesion ndi katundu madzi posungira, etc. Iwo amachita mbali yofunika kwambiri m'munda wa matope okonzeka osakaniza.
Kuchuluka kwa madzi
Cellulose etherZimakhudza kwambiri kusungidwa kwa madzi, kusasinthasintha, ndi ntchito yomanga matope odzipangira okha.Makamaka matope odzipangira okha, fluidity ndi chimodzi mwa zizindikiro zazikulu zowunikira ntchito yodzikweza.Pamaziko owonetsetsa kuti matope apangidwe bwino, madzi amadzimadzi amatha kusinthidwa mwa kusintha kuchuluka kwa cellulose ether.Komabe, mlingo wochuluka kwambiri ungachepetse kusungunuka kwa matope, kotero mlingo wa cellulose ether uyenera kuyendetsedwa mkati mwazokwanira.
Kusunga madzi
Kusungidwa kwamadzi amatope ndi chizindikiro chofunikira choyezera kukhazikika kwa zigawo zamkati zamatope atsopano a simenti.Kuti mukwaniritse bwino momwe ma hydration amachitira ndi zinthu za gel, kuchuluka kwa cellulose ether kumatha kusunga chinyezi mumatope kwa nthawi yayitali.Nthawi zambiri, kuchuluka kwa kasungidwe kwamadzi kwa slurry kumawonjezeka ndi kuchuluka kwa cellulose ether.Ntchito yosungira madzi ya cellulose ether ingalepheretse gawo lapansi kuti lisatenge madzi ochulukirapo mwachangu ndikulepheretsa kutuluka kwa madzi, motero kuwonetsetsa kuti chilengedwe cha slurry chimapereka madzi okwanira a simenti.Kuphatikiza apo, kukhuthala kwa cellulose ether kumathandizanso kwambiri pakusungidwa kwamadzi kwamatope.Kuchuluka kwa mamasukidwe amphamvu, kumapangitsa kuti madzi asungidwe bwino.Ma cellulose ether okhala ndi kukhuthala kwa 400 mpa.
Nthawi ya coagulation
Cellulose etherali ndi vuto linalake pamatope.Pamene zomwe zili mu cellulose ether zikuwonjezeka, nthawi yoyika matope imawonjezeka.Kuchedwetsa kwa cellulose etha pa slurry ya simenti makamaka kumadalira kuchuluka kwa m'malo mwa magulu a alkili ndipo alibe ubale wochepa ndi kulemera kwake kwa maselo.Kuchepa kwa digiri ya alkyl m'malo, kumapangitsa kuti hydroxyl ichuluke, ndipo m'pamenenso zimachedwetsa.Ndipo zomwe zili mu cellulose ether, ndizodziwikiratu kuti filimu yovuta kwambiri ikulepheretsa kuyamwa koyambirira kwa simenti, chifukwa chake, m'pamenenso zimawonekera kwambiri.
Flexural mphamvu ndi compressive mphamvu
Mphamvu ndi chimodzi mwazizindikiro zowunikira zowunikira kulimba kwa zida za simenti zopangidwa ndi simenti pazosakaniza.Pamene zomwe zili mu cellulose ether zikuchulukirachulukira, mphamvu yopondereza ndi mphamvu yosunthika ya matope idzachepa.Iyenera kulamuliridwa pamlingo winawake woyenerera.
Mphamvu yolumikizana
Selulosi ether ali ndi chikoka chachikulu kugwirizana katundu matope.Ma cellulose ether amapanga filimu ya polima ndi kusindikiza pakati pa simenti ya hydration particles mu dongosolo lamadzimadzi, lomwe limalimbikitsa madzi ambiri mu filimu ya polima kunja kwa tinthu tating'ono ta simenti, zomwe zimathandiza kuti hydration yonse ya simenti ikhale yabwino, motero kuwongolera mphamvu ya Bond. pambuyo kuumitsa kwa slurry.Nthawi yomweyo, kuchuluka koyenera kwa cellulose ether kumawonjezera pulasitiki ndi kusinthasintha kwa matope, kumachepetsa kusasunthika kwa malo osinthira pakati pa matope ndi zinthu zoyambira, ndikuchepetsa kuthekera kotsetsereka pakati pa zolumikizira.Pamlingo wina, kulumikizana pakati pa matope ndi zinthu zoyambira kumakulitsidwa.Komanso, chifukwa cha kukhalapo kwa mapadi efa mu slurry simenti, wapadera mawonekedwe zone kusintha ndi mawonekedwe wosanjikiza aumbike pakati pa matope particles ndi mankhwala hydration.Izi mawonekedwe wosanjikiza zimapangitsa mawonekedwe kusintha zone zambiri kusinthasintha ndi m'munsi okhwima.Choncho, , kotero kuti matope ali ndi mphamvu zomangira zolimba.
