Matope okhathamira amatha kudalira kulemera kwake kuti apange maziko athyathyathya, yosalala komanso yolimba pagawo lapansi pogona kapena kukanda zinthu zina, ndipo nthawi yomweyo imatha kugwira ntchito zazikulu komanso zomanga bwino komanso zomanga bwino. Chifukwa chake, madzi amtunduwu ndi gawo lofunikira kwambiri pakudzipangitsa nokha. Kuphatikiza apo, iyenera kukhala ndi chitetezo china chamadzi ndi mphamvu ya madzi, palibe mphamvu zam'madzi zophatikiza, ndipo khalani ndi mikhalidwe ya kutentha kutentha ndi kutentha kochepa.
Nthawi zambiri, matope omwe amadzilimbitsa okha amafunikira madzi abwino, koma madzi amtundu weniweni wa simenti nthawi zambiri amakhala 10-300px; cellulose ether ndi chowonjezera cha matope osakanizika, ngakhale kuchuluka kwake kumakhala kochepa kwambiri, kumatha kusintha matope, kumatha kukonza kusasinthika, kugwira ntchito, kugwira ntchito ndi kusunga madzi ndi magwiridwe antchito a matope. Imagwira ntchito yofunika kwambiri m'munda wamatope osakanikirana.
1. Madzimadzi: cellulose ether ali ndi mphamvu yofunika posungira madzi, kusinthasintha komanso zomanga zodzipangira matope okha. Makamaka monga matope odzilimbitsa okha, madzi amtundu ndi chimodzi mwazizindikiro zazikulu zowunikira zolimbitsa thupi. Pansi pa kuwonetsetsa kuti mwakhala ndi matope, madzi amtondowo amatha kusinthidwa posintha kuchuluka kwa maselo a cellulose. Komabe, ngati kuchuluka kwake kuli kochepa kwambiri, madzimadzi a matope adzachepetsedwa, kuchuluka kwa cellulose ether hpmc kuyenera kulamulidwa m'njira zoyenera.
2. Kusunga kwamadzi: Kusunga kwamadzi kwa matope ndi chizindikiro chofunikira kuti muyeze kukhazikika kwa zinthu zamkati mwa matope osakanikirana. Kuti muchitepo kanthu mokwanira za gel, kuchuluka kwa ethel ether kumatha kukhala chinyontho mu matope kwa nthawi yayitali. Nthawi zambiri, kusunga madzi kwa masitolo kumawonjezeka ndi kuchuluka kwa cellulose ether. Kusunga kwamadzi kwa cellulose ether hpmc kungalepheretse madzi ambiri mwachangu, ndikulepheretsa madzi oseketsa, kuti malo otsekemera awonetsetse madzi oseketsa a simenti hydration. Kuphatikiza apo, mafayilo a cellulose ether alinso ndi chidwi chachikulu pamadzi osungira. Maonekedwe akuwoneka, abwinobwino madzi. Nthawi zambiri, cellulose epmc yokhala ndi mafayilo a 400mpa.
3. Kukhazikitsa nthawi: cellulose ether ali ndi mphamvu yofananira ndi matope. Ndi kuwonjezeka kwa zomwe zili mu cellulose ether, nthawi yokhazikitsa matope. Kubwezeretsanso kwa cellulose ether hpmc pa simenti pa simenti pagawo makamaka kumadalira kuchuluka kwa gulu la gulu la alkyl, ndipo alibe ubale wochepa ndi kulemera kwake. Zocheperako kuchuluka kwa alkyl kuloweza, kwakukulu ndi ma hydroxyl, komanso zowonekeratu zobwezera. Ndipo zokulira zomwe zili ndi ether ether, zowonekeratu kuti zikuchedwa kuchedwa kwa filimu yovuta ya simenti, kotero kuti kubwezeretsanso kuli kodziwikiratu.
4. Flemic Mphamvu ndi Mphamvu Yopsinjika: Nthawi zambiri, mphamvu ndi imodzi mwazowunika koyenera pochirikiza zinthu zochirikiza za simenti pazinthu zosakaniza. Mphamvu yomuphwanya yolemetsa ndi kuthekera kwa matope imachepera ndi kuchuluka kwa cellulose ether.
5. Mphamvu Yogwirizanitsa: Cellulose ether hpmc imakhala ndi mphamvu kwambiri pa matope a matope. Cellulose ether filimu ya polymer ndi chipilala chomwe chimakhala pakati pa tinthu tating'onoting'ono tambiri tomwe timadzimadzi, zomwe zimalimbikitsa madzi ambiri pagawo la simemer, ndikuwongolera mphamvu ya phala pambuyo polimbana. Nthawi yomweyo, kuchuluka kwa ma cellulose kumawonjezera matope ndi kusintha kwa matope, kumachepetsa kukhazikika kwa malo osinthira pakati pa matope ndi mawonekedwe a gawo lapansi pakati pa mawonekedwe. Kufikira pamlingo winawake, kulumikizana pakati pa matope ndi gawo lapansi kumakulitsidwa. Kuphatikiza apo, chifukwa cha kukhalapo kwa ma cellulose mu phala la simenti, malo apadera oyenda ndi mawonekedwe a mawonekedwe amapangidwa pakati pa mavuwo ndi mankhwala opatsa mphamvu. Izi zimapangitsa mawonekedwe otseguka mawonekedwe osinthasintha komanso okhazikika, kotero, kotero kuti chilombocho chili ndi mphamvu yamphamvu.
