1.Kunyowa matope osakanikirana: matope osakanikirana ndi mtundu wa simenti, ophatikizana bwino, osakaniza ndi madzi, ndipo malinga ndi katundu wa zigawo zosiyanasiyana, malinga ndi chiwerengero china, atayesedwa pa malo osakaniza, osakaniza, amatumizidwa kumalo omwe galimotoyo imagwiritsidwa ntchito, ndikulowa mu Sitolo yapadera ya chidebecho ndikugwiritsa ntchito kusakaniza konyowa komaliza kwa nthawi yomwe yatchulidwa.
2.Hydroxypropyl methyl cellulose imagwiritsidwa ntchito ngati chosungira madzi pamatope a simenti ndi retarder popopera matope. Pankhani ya gypsum ngati chomangira kuti chiwongolere ntchito ndikutalikitsa nthawi yogwira ntchito, kusungidwa kwa madzi kwa HPMC kumalepheretsa slurry kusweka mwachangu mukatha kuyanika, ndikuwonjezera mphamvu pambuyo poumitsa. Kusunga madzi ndi chinthu chofunikira kwambiri cha hydroxypropyl methyl cellulose HPMC, komanso ndi nkhawa ya opanga matope ambiri apanyumba. Zomwe zimakhudza momwe madzi amasungiramo matope osakanikirana amaphatikizapo kuchuluka kwa HPMC yowonjezeredwa, kukhuthala kwa HPMC, ubwino wa tinthu tating'onoting'ono komanso kutentha kwa malo ogwiritsira ntchito.
3.Ntchito zazikulu za hydroxypropyl methyl celluloseMtengo wa HPMCmu matope wothira wothira makamaka mbali zitatu, imodzi ndi yabwino madzi kugwira mphamvu, wina ndi chikoka pa kusasinthasintha ndi thixotropy wa chonyowa wothira matope, ndipo chachitatu ndi mogwirizana ndi simenti . Kusungidwa kwa madzi a cellulose ether kumadalira kuchuluka kwa mayamwidwe amadzi a m'munsi, kapangidwe ka matope, makulidwe a matope osanjikiza, kuchuluka kwa madzi kwa matope, ndi nthawi yoyika. Kuwoneka bwino kwa hydroxypropyl methyl cellulose kumapangitsa kuti madzi asungidwe bwino.
4.Zomwe zimakhudza kusungidwa kwa madzi kwa matope osakaniza onyowa ndi ma cellulose ether viscosity, kuchuluka kwake, kukula kwa tinthu ndi kutentha. 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 kugwiritsa ntchito njira zosiyanasiyana zoyezera kukhuthala zimasiyana kwambiri, ndipo ena amakhala ndi kusiyana kawiri. Choncho, kuyerekezera mamasukidwe akayendedwe ayenera kuchitidwa mu njira yoyesera yofanana, kuphatikizapo kutentha, spindle, etc.
5.Nthawi zambiri, kumtunda kwa viscosity, ndi bwino kusunga madzi. Komabe, kukhuthala kwamphamvu, kumapangitsa kuti HPMC ikhale yolemera kwambiri komanso kutsika kwa kusungunuka kwa HPMC, komwe kumakhudza kwambiri mphamvu ndi ntchito yomanga matope. Kuchuluka kwa mamasukidwe akayendedwe, kumapangitsa kuti matopewo achuluke kwambiri, koma sizigwirizana mwachindunji. Kukwezeka kwa viscosity, matope amadzimadzi amawonekera kwambiri, ntchito yomanga bwino, ntchito ya viscous scraper ndipamwamba kumamatira ku gawo lapansi. Komabe, kuwonjezereka kwamphamvu kwapangidwe kwa matope okhawo sikuthandiza. Zomanga ziwirizi zilibe ntchito zodziwikiratu zotsutsana ndi sag. Mosiyana ndi izi, ma viscosity ena apakati komanso otsika koma osinthidwa hydroxypropyl methyl cellulose ali ndi ntchito yabwino kwambiri pakuwongolera mphamvu zamapangidwe amatope onyowa.
6.Kuchuluka kwa cellulose ether kuwonjezeredwa ku matope a HPMC onyowa, kusungirako bwino kwa madzi, komanso kukwezeka kwa viscosity, ndi bwino kusunga madzi. Fineness ndiwonso gawo lofunikira la hydroxypropyl methyl cellulose.
7.Kukongola kwa hydroxypropyl methyl cellulose kumakhalanso ndi chikoka pa kusunga madzi. Nthawi zambiri, pa hydroxypropyl methyl cellulose yokhala ndi kukhuthala kofanana ndi kukongola kosiyana, kucheperako kumachepetsa, kumachepetsa kuchepa kwa madzi pansi pa kuchuluka komweko. chabwino.
8.Mu matope osakanikirana ndi madzi, kuchuluka kwa cellulose ether HPMC kumakhala kochepa kwambiri, koma kungathe kupititsa patsogolo ntchito yomanga matope, ndipo ndicho chowonjezera chachikulu chomwe chimakhudza makamaka ntchito ya matope. Kusankhidwa koyenera kwa hydroxypropyl methyl cellulose, magwiridwe antchito amatope amakhudzidwa kwambiri.
