Mtondo wosakanizidwa ndi madzi ndi simenti, zophatikizika bwino, zophatikizika, madzi ndi zinthu zosiyanasiyana zomwe zimatsimikiziridwa malinga ndi magwiridwe antchito.Malingana ndi gawo lina, pambuyo poyesedwa ndi kusakaniza mu malo osakaniza, amatumizidwa kumalo ogwiritsidwa ntchito ndi galimoto yosakaniza, ndikuyika mu wapadera Kusakaniza konyowa kumasungidwa mu chidebe ndikugwiritsidwa ntchito mkati mwa nthawi yotchulidwa.
Hydroxypropyl methylcellulose imagwiritsidwa ntchito ngati chosungira madzi komanso chobwezeretsanso matope a simenti kuti matopewo azipopa.Imagwiritsidwa ntchito ngati chomangira popaka pulasitala, imathandizira kufalikira ndikutalikitsa nthawi yogwira ntchito.Kusunga madzi kwa hydroxypropyl methylcellulose HPMC kumalepheretsa slurry kuti zisaphwanyike chifukwa chowuma mwachangu mukatha kugwiritsa ntchito, ndikuwonjezera mphamvu pambuyo poumitsa.Kusunga madzi ndi ntchito yofunika kwambiri ya hydroxypropyl methylcellulose HPMC, komanso ndikuchita komwe ambiri opanga matope ophatikizika apanyumba amalabadira.Zomwe zimakhudza momwe madzi amasungiramo matope osakanikirana ndi madzi amaphatikizapo kuchuluka kwa HPMC yowonjezeredwa, kukhuthala kwa HPMC, ubwino wa tinthu tating'onoting'ono, komanso kutentha kwa malo ogwiritsira ntchito.
Udindo wofunikira wa hydroxypropyl methylcellulose HPMC mumtondo wonyowa wothira makamaka uli ndi mbali zitatu, imodzi ndi yabwino kwambiri yosungira madzi, inayo imakhudza kusasinthasintha ndi thixotropy wa matope osakaniza, ndipo chachitatu ndi kugwirizana ndi simenti.Mphamvu yosungira madzi ya cellulose ether imatengera kuyamwa kwamadzi kwa gawo loyambira, kapangidwe ka matope, makulidwe a matope, kuchuluka kwa madzi amatope, komanso nthawi yoyikapo.Kuwoneka bwino kwa hydroxypropyl methylcellulose kumapangitsa kuti madzi asungidwe bwino.
Zomwe zimakhudza kusungidwa kwamadzi kwa matope osakaniza onyowa ndi ma cellulose ether viscosity, kuchuluka kowonjezera, kununkhira kwa tinthu ndi kutentha kwa ntchito.Kuchuluka kwa kukhuthala kwa cellulose ether, kumapangitsa kuti madzi asungidwe bwino.Viscosity ndi gawo lofunikira la magwiridwe antchito a HPMC.Kwa mankhwala omwewo, zotsatira za viscosity zoyezedwa ndi njira zosiyanasiyana ndizosiyana kwambiri, ndipo zina zimakhala zosiyana kawiri.Chifukwa chake, poyerekeza kukhuthala, kuyenera kuchitidwa pakati pa njira zoyesera zomwezo, kuphatikiza kutentha, rotor, ndi zina.
Nthawi zambiri, kukwezeka kwa mamachulukidwe kumapangitsa kuti madzi asungidwe bwino.Komabe, kukwezeka kwa mamasukidwe apamwamba komanso kulemera kwa mamolekyu a HPMC, kutsika kofananirako kusungunuka kwake kudzakhala ndi zotsatira zoyipa pamphamvu ndi ntchito yomanga ya matope.The apamwamba mamasukidwe akayendedwe, ndi zoonekeratu kwambiri thickening zotsatira pa matope, koma si mwachindunji molingana.Kukwera kwa mamasukidwe akayendedwe, m'pamenenso matope onyowa amakhala owoneka bwino kwambiri, ndiye kuti, pakumanga, amawonetsedwa ngati kumamatira ku scraper ndi kumamatira kwakukulu ku gawo lapansi.Koma sizothandiza kuwonjezera mphamvu zamapangidwe a dothi lonyowa palokha.Pakumanga, ntchito yotsutsa-sag sizowonekera.M'malo mwake, hydroxypropyl methylcellulose yosinthidwa yokhala ndi mamasukidwe apakatikati ndi otsika imakhala ndi ntchito yabwino kwambiri pakuwongolera mphamvu zamapangidwe amatope onyowa.
Kuchuluka kwa cellulose ether HPMC yowonjezeredwa mumatope osakanikirana ndi madzi, kumapangitsa kuti madzi asamasungidwe bwino, komanso kukwezeka kwamphamvu, kumapangitsa kuti madzi asungidwe bwino.Fineness ndiwonso gawo lofunikira la hydroxypropyl methylcellulose.
Ubwino wa hydroxypropyl methylcellulose umakhudzanso kusungidwa kwa madzi.Nthawi zambiri, pa hydroxypropyl methylcellulose yokhala ndi mamasukidwe ofanana koma ubwino wosiyana, uwongopawo umakhala wowoneka bwino kwambiri Mphamvu yosunga madzi imakhala yabwinoko.
Mumatope osakanikirana ndi madzi, kuchuluka kwa cellulose ether HPMC kumakhala kochepa kwambiri, koma kumatha kusintha kwambiri ntchito yomanga matope osakanikirana, ndipo ndi chowonjezera chachikulu chomwe chimakhudza ntchito yomanga matope.Kusankhidwa koyenera kwa hydroxypropyl methylcellulose kumakhudza kwambiri kusintha kwa ntchito ya matope osakanikirana ndi madzi.
