Mtondo wosakaniza wonyowa: Mtondo wosakaniza ndi mtundu wa simenti, wosakaniza bwino, wosakaniza ndi madzi, ndipo malinga ndi makhalidwe a zigawo zosiyanasiyana, malinga ndi chiŵerengero china, pambuyo poyezedwa pamalo osakaniza, wosakaniza, wonyamulidwa kupita kumalo komwe galimotoyo ikugwiritsidwa ntchito, ndikulowetsedwa mu malo apadera. Sungani chidebecho ndikugwiritsa ntchito chisakanizo chonyowa chomalizidwa kwa nthawi yomwe yatchulidwa.
Hydroxypropyl methylcellulose imagwiritsidwa ntchito ngati chosungira madzi cha matope a simenti ndi retarder popopera matope. Pankhani ya gypsum ngati chomangira kuti chigwiritsidwe ntchito bwino ndikuwonjezera nthawi yogwira ntchito, kusunga madzi kwa HPMC kumalepheretsa matope kusweka mwachangu atauma, ndipo kumawonjezera mphamvu pambuyo pouma. Kusunga madzi ndi chinthu chofunikira kwambiri cha hydroxypropyl methylcellulose HPMC, ndipo ndi nkhawa ya opanga matope ambiri osakaniza madzi m'nyumba. Zinthu zomwe zimakhudza momwe matope osakaniza madzi amasungidwira ndi monga kuchuluka kwa HPMC komwe kumawonjezeredwa, kukhuthala kwa HPMC, kusalala kwa tinthu tating'onoting'ono ndi kutentha kwa malo ogwiritsidwa ntchito.
Pali ntchito zitatu zazikulu za hydroxypropyl methylcellulose HPMC mu matope osakaniza ndi madzi, imodzi ndi mphamvu yabwino kwambiri yosungira madzi, ina ndi mphamvu pa kusinthasintha ndi thixotropy ya matope osakaniza ndi madzi, ndipo yachitatu ndi kuyanjana ndi simenti. Kusunga madzi kwa ether ya cellulose kumadalira kuchuluka kwa kuyamwa kwa madzi kwa maziko, kapangidwe ka matope, makulidwe a matope, kufunikira kwa madzi kwa matope, ndi nthawi yoyika. Kuwonekera kwa hydroxypropyl methylcellulose kukakhala kwakukulu, kusunga madzi kumakhala bwino.
Zinthu zomwe zimakhudza kusunga madzi mu matope osakaniza ndi madzi ndi monga kukhuthala kwa ether ya cellulose, kuchuluka kwa kuwonjezera, kukula kwa tinthu tating'onoting'ono ndi kutentha. Kukhuthala kwa ether ya cellulose kukakhala kwakukulu, kusunga madzi kumakhala bwino. Kukhuthala ndi gawo lofunikira pakugwira ntchito kwa HPMC. Pa chinthu chomwecho, zotsatira za kugwiritsa ntchito njira zosiyanasiyana poyesa kukhuthala zimasiyana kwambiri, ndipo zina zimakhala ndi mipata iwiri. Chifukwa chake, kufananiza kukhuthala kuyenera kuchitika mwanjira yoyesera yomweyo, kuphatikiza kutentha, spindle, ndi zina zotero.
Kawirikawiri, kukhuthala kwa madzi kumakhala kwakukulu, ndipo madzi amasungidwa bwino. Komabe, kukhuthala kwa HPMC kumakhala kwakukulu, ndipo kusungunuka kwa HPMC kumakhala kochepa, zomwe zimakhudza mphamvu ndi kapangidwe ka matope. Kukhuthala kwa matope kumakhala kwakukulu, ndipo kukhuthala kwa matope kumakhala koonekera bwino, koma sikukhudzana mwachindunji. Kukhuthala kwa matope kumakhala kwakukulu, ndipo kukhuthala kwa matope kumakhala kolimba, ndipo kapangidwe kake kamakhala bwino, ndipo scraper yokhuthala imagwirira ntchito bwino komanso kumamatira ku substrate kumawonjezeka. Komabe, mphamvu yowonjezereka ya matope onyowa yokha siithandiza. Mapangidwe awiriwa alibe mphamvu yodziwika bwino yotsutsana ndi kutsika. Mosiyana ndi zimenezi, kukhuthala kwapakati ndi kotsika koma kosinthidwa hydroxypropyl methylcellulose kumakhala ndi ntchito yabwino kwambiri pakukweza mphamvu ya matope onyowa.
Kuchuluka kwa ether ya cellulose yowonjezeredwa ku matope onyowa a PMC, kumakhala bwino kusunga madzi, ndipo kukhuthala kwake kumakhala kwakukulu, kumakhala bwino kusunga madzi. Kusalala kwake ndi chizindikiro chofunikira cha hydroxypropyl methylcellulose.
Kusalala kwa hydroxypropyl methylcellulose kumakhudzanso kusunga madzi. Kawirikawiri, pa hydroxypropyl methylcellulose yokhala ndi kukhuthala kofanana ndi kusalala kosiyana, kuchepa kwake kukakhala kochepa, kuchepa kwake kumakhala kochepa posunga madzi pansi pa kuchuluka komweko kowonjezera. Ndikobwino.
Mu matope osakanikirana ndi madzi, kuchuluka kwa ether ya cellulose HPMC kumakhala kochepa kwambiri, koma kumatha kusintha kwambiri magwiridwe antchito a matope onyowa, ndipo ndicho chowonjezera chachikulu chomwe chimakhudza kwambiri magwiridwe antchito a matope. Kusankha koyenera kwa hydroxypropyl methylcellulose, magwiridwe antchito a matope onyowa amakhudzidwa kwambiri.
