Udaka olumanzi olumanzi: Udaka oluxubile luhlobo losekhulile, okuhlanganisiwe okuhle, ukuhlanganiswa kwamanzi, kanye nokukalwa esiteshini esihlukahlukene, esitsheni esibekiwe, kusetshenziswe isikhathi esibekiwe senhlanganisela ebekiwe.
I-Hydroxypropyllylylylyllllulose isetshenziswa njenge-ejenti yokugcina amanzi ngodaka kasimende, i-retarder durdarder pump. Ku-gypsum njenge-binder ukuze uthuthukise uhlelo lokusebenza futhi unwebe isikhathi sokusebenza, i-hydroxypropyll methylcellulose hpmc yokugcinwa kwamanzi ukuze ukomiswa ngemuva kokomiswa kungabi ngokushesha okukhulu futhi kube lukhuni ukuthuthukisa amandla. Ukugcinwa kwamanzi kuyindawo ebalulekile ye-hydroxypropyllylylylylylylylylylylylylylylylylylylyll methyllulose hpmc, futhi kungukuthi ukukhathazeka kwalabo abakhiqizi abaningi abamanzi. Izici ezithinta umphumela wokugcinwa kwamanzi we-water fortar zifaka inani le-HPMC elingeziwe, i-viscosity ye-HPMC, ukubusa kwezinhlayiya kanye nokushisa kwendawo yokusebenzisa.
I-Hydroxypropylylylylylylylyll pulvu Ukugcinwa kwamanzi kwe-cellulose kuncike emazingeni okufakwa kwamanzi kwesisekelo, ukwakheka kodaka kodumbu, ukuqina kwamanzi kodaka, ukufunwa kwamanzi kodaka, ukusetha isikhathi. Lapho kuphakama okusobala kwe-hydroxypropyllylylylylylylyl, okungcono ukugcinwa kwamanzi.
Izici ezithinta ukugcinwa kwamanzi ngodaka olumanzi kufaka phakathi ukubonakala kwe-cellulose ether, ukungeza inani, usayizi wezinhlayiyana kanye nokushisa. Lapho kukhuphuka khona i-viscose ether, kungcono ukugcinwa kwamanzi. I-Viscosity iyipharamitha ebalulekile yokusebenza kwe-HPMC. Kumkhiqizo ofanayo, usebenzisa izindlela ezahlukahlukene ukukala i-viscosity yemiphumela iyahlukahluka kakhulu, ezinye ngisho nangesici sababili. Ngakho-ke, ukuqhathanisa kwe-viscosity kumele kwenziwe ngendlela efanayo yokuhlola, kufaka phakathi izinga lokushisa, i-rotor, njll.
Ngokuvamile, kuphakama i-viscosity, kungcono ukugcinwa kwamanzi. Kodwa-ke, ukukhuphuka kwesisindo esiphakeme, isisindo samangqamuzana se-HPMC, kanye ne-solubity ye-HPMC, enomthelela omubi emandleni nasekusebenzeni kokwakha kodaka. Lapho kuphakama i-viscosity, kusobala kakhulu umphumela wodaka, kepha ahlobene ngqo. Lapho esekhuphuka i-viscosity, okunamathelayo ngodaka olumanzi, ukusebenza okuhle kokwakha, ukusebenza kwe-viscous scraper kanye nokunamathelisa okuphezulu kuya engxenyeni engezansi. Kodwa-ke, ukuthuthuka kwamandla enhlaka kasidaka olumanzi ngokwalo akuzange kusize. Womabili lokwakha, ukusebenza akubonakali anti - Ukulenga ukusebenza. Ngokuphambene nalokho, ukubukeka okuphakathi nendawo okuphansi kodwa okuguquliwe i-hydroxypropyllylyly methylcellulose kusebenza kahle kakhulu ekuthuthukiseni amandla ahlelekile ngodaka olumanzi.
Lapho imali enkulu ka-cellulose ether pmc emanzi i-PMC yengezwe, okungcono ukugcinwa kwamanzi, kukhuphuka okuvelele, kungcono ukugcinwa kwamanzi. I-Fechness nayo iyinkomba yokusebenza ebalulekile ye-hydroxypropyllylylylylylylylylylylylyl.
Ubumsulwa be-hydroxypropylllylylylylylylylylylloose buye bube nethonya elithile ekugcinweni kwalo kwamanzi. Ngaphansi kwezimo ezijwayelekile, ukubukeka okufanayo nobunzima obuhlukile be-hydroxypropyllylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylyllylylylylylyl methyl cellulose, ngaphansi kwenani elifanayo lokwengezwa, incane ubumsulwa bomphumela wokugcina amanzi bungcono.
Ku-datarter emanzi, ukungezwa kwe-cellulose ether hpmc kuphansi kakhulu, kepha kungathuthukisa kakhulu ukusebenza kosuku lwamanzi, kuyisengezo esikhulu esithinta kakhulu ukusebenza ngodaka. Ukusebenza kodaka olumanzi kuthonywa kakhulu ukukhethwa okufanele kwe-hydroxypropylylylylylylylylylyllop methyl
