Mtondo wosakaniza ndi simenti, chosakaniza bwino, chosakanizira, madzi ndi zinthu zosiyanasiyana zomwe zimatsimikiziridwa malinga ndi momwe zinthu zilili. Malinga ndi kuchuluka kwake, pambuyo poyezedwa ndikusakanizidwa mu siteshoni yosakanizira, umasamutsidwa kupita kumalo ogwiritsidwa ntchito ndi galimoto yosakanizira, ndikuyikidwa mu chipangizo chapadera. Chosakaniza chonyowa chimasungidwa mu chidebe ndikugwiritsidwa ntchito mkati mwa nthawi yomwe yatchulidwa.
Hydroxypropyl methylcellulose imagwiritsidwa ntchito ngati chosungira madzi komanso choletsa simenti kuti matopewo azitha kupopedwa. Imagwiritsidwa ntchito ngati chomangira mu pulasitala, imapangitsa kuti madzi azitha kufalikira komanso imawonjezera nthawi yogwira ntchito. Kagwiridwe ka ntchito ka hydroxypropyl methylcellulose HPMC kosunga madzi kumalepheretsa matope kusweka chifukwa chouma mwachangu kwambiri mutagwiritsa ntchito, ndipo kumawonjezera mphamvu pambuyo pouma. Kusunga madzi ndi ntchito yofunika kwambiri ya hydroxypropyl methylcellulose HPMC, komanso ndi ntchito yomwe opanga matope ambiri osakaniza madzi m'nyumba amasamala. Zinthu zomwe zimakhudza momwe matope osakaniza madzi amasungira madzi ndi monga kuchuluka kwa HPMC komwe kumawonjezeredwa, kukhuthala kwa HPMC, kusalala kwa tinthu tating'onoting'ono, ndi kutentha kwa malo ogwiritsira ntchito.
Udindo wofunikira wa hydroxypropyl methylcellulose HPMC mu matope osakaniza madzi uli ndi mbali zitatu, chimodzi ndi mphamvu yabwino kwambiri yosungira madzi, china ndi momwe matope osakaniza madzi amagwirira ntchito komanso momwe amagwirira ntchito, ndipo chachitatu ndi momwe matope osakaniza madzi amagwirira ntchito ndi simenti. Mphamvu yosungira madzi ya cellulose ether imadalira kuyamwa kwa madzi kwa maziko, kapangidwe ka matope, makulidwe a matope, kufunika kwa madzi kwa matope, komanso nthawi yoyika zinthu. Pamene hydroxypropyl methylcellulose ikuwonekera bwino, madzi amasungidwa bwino.
Zinthu zomwe zimakhudza kusunga madzi mu matope osakaniza ndi madzi ndi monga kukhuthala kwa etha ya cellulose, kuchuluka kwa kuwonjezera, kusalala kwa tinthu tating'onoting'ono ndi kutentha kwa ntchito. Kukhuthala kwa etha ya cellulose kumakhala kwakukulu, kumachititsanso kuti kusunga madzi kukhale bwino. Kukhuthala ndi gawo lofunika kwambiri pakugwira ntchito kwa HPMC. Pa chinthu chomwecho, zotsatira za kukhuthala zomwe zimayesedwa ndi njira zosiyanasiyana zimakhala zosiyana kwambiri, ndipo zina zimakhala ndi kusiyana kawiri. Chifukwa chake, poyerekeza kukhuthala, ziyenera kuchitika pakati pa njira zoyesera zomwezo, kuphatikizapo kutentha, rotor, ndi zina zotero.
Kawirikawiri, kukhuthala kwa madzi kukakhala kwakukulu, kumakhala bwino kwambiri. Komabe, kukhuthala kwa madzi kukakhala kwakukulu komanso kulemera kwa mamolekyulu a HPMC kukakhala kwakukulu, kuchepa kofanana kwa kusungunuka kwake kudzakhala ndi zotsatira zoyipa pa mphamvu ndi magwiridwe antchito a matope. Kukhuthala kwa madzi kukakhala kwakukulu, kukhuthala kwa matope kumakhala koonekera bwino, koma sikufanana mwachindunji. Kukhuthala kwa madzi kukakhala kwakukulu, kukhuthala kwa matope onyowa kumakhala kolimba kwambiri, ndiko kuti, panthawi yomanga, kumaonekera ngati kumamatira ku scraper ndi kumamatira kwambiri ku substrate. Koma sizothandiza kuwonjezera mphamvu ya matope onyowa okha. Panthawi yomanga, mphamvu yotsutsana ndi kusagwa siidziwika. M'malo mwake, hydroxypropyl methylcellulose yosinthidwa yokhala ndi kukhuthala kwapakati komanso kotsika imakhala ndi magwiridwe antchito abwino kwambiri pakukweza mphamvu ya matope onyowa.
Kuchuluka kwa ether ya cellulose HPMC yowonjezeredwa mu matope osakanikirana ndi madzi, kumakhala bwino kusunga madzi, ndipo kukhuthala kwake kumakhala kwakukulu, kumakhala bwino kusunga madzi. Kusalala ndi chizindikiro chofunikira cha magwiridwe antchito a hydroxypropyl methylcellulose.
Kusalala kwa hydroxypropyl methylcellulose kumakhudzanso kusunga madzi. Kawirikawiri, hydroxypropyl methylcellulose yokhala ndi kukhuthala komweko koma kusalala kosiyana, kusalala kocheperako kumakhala kocheperako. Zotsatira za kusunga madzi zimakhala bwino.
Mu matope osakanikirana ndi madzi, kuchuluka kwa HPMC yowonjezera ya cellulose ether kumakhala kochepa kwambiri, koma kumatha kusintha kwambiri magwiridwe antchito a matope osakanikirana ndi madzi, ndipo ndi chowonjezera chachikulu chomwe chimakhudza magwiridwe antchito a matope. Kusankha bwino hydroxypropyl methylcellulose yoyenera kumakhudza kwambiri magwiridwe antchito a matope osakanikirana ndi madzi.
