I-1.wet udaka oluhlanganisiwe: Udaka oluxubile luhlobo lwesimende, i-aggregate enhle, ukuhlangana namanzi, futhi ngokuya ngesilinganiso esikhethekile, bese ungena esitolo esikhethekile esitsheni bese usebenzisa ingxube eseqedile yesikhathi esichaziwe.
I-2.hydroxypropyllyllylylylylylyll pullulose isetshenziswa njenge-ejenti yokugcina amanzi ngodaka kasimende kanye ne-retarder ye-dollar mpompe. Endabeni ye-gypsum njenge-binder yokuthuthukisa uhlelo lokusebenza lwe-application kanye nesikhathi esandisa khona, ukugcinwa kwamanzi kwe-HPMC kuvimbela ama-slurry kusuka ekuqhekekeni ngokushesha okukhulu ngemuva kokomiswa, futhi kuthuthukise amandla ngemuva kokuqina. Ukugcinwa kwamanzi kuyindawo ebalulekile ye-hydroxypropylylylylylylyll methyl cellulose hpmc, futhi futhi ukukhathazeka kwabakhiqizi abaningi basemakhaya abaxubayo basemakhaya. Izici ezithinta umphumela wokugcinwa kwamanzi ngodaka oluxutshwe olumanzi lubandakanya inani le-HPMC elingeziwe, ukubonwa kwe-HPMC, ukubusa kwezinhlayiya kanye nokushisa kwendawo yokusebenzisa.
3.Imisebenzi eyinhloko ye-hydroxypropyllylylylyllyllllll pullulose HPMC ngodaka oluyiminyene olumanzi ikakhulukazi, enye ithonya lokuvumelana kwamanzi, kanti elinye liyithonya lodaka olumanzi, kanti lwesithathu kungukusebenzisana nosimende. Ukugcinwa kwamanzi kwe-cellulose ether kuya ngesilinganiso sokutholwa kwamanzi kwesisekelo, ukwakheka kodaka, ukushuba kongqimba lwesidakamizwa, ukufunwa kwamanzi ngodaka, kanye nesikhathi sokusetha. Lapho kuphakama okusobala kwe-hydroxypropyllylylylylylylyl, okungcono ukugcinwa kwamanzi.
Abakwa-4.Factors bathinta ukugcinwa kwamanzi kodaka oluxutshwe namanzi kufaka i-cellulose ether vispelity, inani lokungezelela, usayizi wezinhlayiyana kanye nokushisa. Lapho kukhuphuka khona i-viscose ether, kungcono ukugcinwa kwamanzi. I-Viscosity iyipharamitha ebalulekile yokusebenza kwe-HPMC. Ngomkhiqizo ofanayo, imiphumela yokusebenzisa izindlela ezahlukahlukene ukukala ukubonakala kwehlukahluka kakhulu, futhi abanye banegebe eliphindwe kabili. Ngakho-ke, ukuqhathanisa kwe-viscosity kumele kwenziwe ngendlela efanayo yokuhlola, kufaka phakathi izinga lokushisa, i-spindle, njll.
Ngokwezwisisa, okuphezulu kwe-viscosity, kungcono ukugcinwa kwamanzi. Kodwa-ke, ukukhuphuka kwesisindo esiphakeme, isisindo esiphakeme se-HPMC kanye ne-solubity ye-HPMC, enomthelela ongemuhle emandleni nasekwenzeni kokwakha kodaka. Lapho kuphakama i-viscosity, kusobala kakhulu umphumela wokuqina wodaka, kepha ahlobene ngqo. Lapho esekhuphuka i-viscosity, i-viscous mores ngodaka olumanzi, ingcono ukusebenza kwezokwakha, ukusebenza kwesikhafu se-viscous kanye nokunamathela ku-substrate. Kodwa-ke, amandla esandayo enhlaka kadaka olumanzi uqobo alusizi. Lezi zakhiwo ezimbili azinawo ukusebenza okusobala kwe-anti-sag. Ngokuphambene nalokho, ukuhlakanipha okuphakathi nendawo okuphansi kodwa okulungiselelwe i-hydroxypropylllylylylylylylyly methyl celtule
6.Umakhulu inani le-cellulose ether elingezwe ku-HPMC Wet Data, okungcono ukugcinwa kwamanzi, kanye nokuphakama okuphezulu, kungcono ukugcinwa kwamanzi. I-Fechness nayo iyinkomba yokusebenza ebalulekile ye-hydroxypropyllylylylylylylylylylylylyl.
7.Ubuwula be-hydroxypropylllylylylylylylylyllllllle futhi unethonya elithile ekugcinweni kwalo kwamanzi. Ngokuvamile, nge-hydroxypropyllylylylylyl puelsose ngokubonakala okufanayo nobunzima obuhlukile, okuncane okubucayi, okuncane okubuyiselwa kwamanzi okutholakale ngaphansi kwenani elifanayo lezengezo. okungcono.
8. Udaka oluxutshwe olumanzi, inani lokungezwa le-cellulose ether hpmc liphansi kakhulu, kepha lingathuthukisa kakhulu ukusebenza kosuku lodaka lwamanzi, futhi yisengezo esikhulu esithinta kakhulu ukusebenza ngodaka. Ukukhetha okufanele kwe-hydroxypropyllylylylylylylylylylyllose, ukusebenza ngodaka olumanzi kuthinteke kakhulu.
