Ukugcinwa kwamanzi kusukaI-Hydroxypropyl Methyl Celluloseingenye yezimpawu ezibalulekile ze-Hydroxypropyl Methyl Cellulose. Izici ezifana nokushisa komoya, izinga lokushisa kanye nesivinini sokucindezela komoya kuzothinta izinga lokuguquguquka kwamanzi emikhiqizweni yesamente kanye nemikhiqizo esekelwe ku-gypsum. Ngakho-ke, ezinkathini ezahlukene, kunomehluko othile emphumeleni wokugcina amanzi wemikhiqizo enenani elifanayo le-Hydroxypropyl Methyl Cellulose elingeziwe.
Ngokuvamile, uma i-viscosity ye-Hydroxypropyl Methyl Cellulose iphakeme, umphumela wokugcina amanzi uzoba ngcono, kodwa umphumela we-viscosity ekugcinweni kwamanzi uzoncishiswa lapho i-viscosity idlula ama-mpa ayi-100,000. Ku-Hydroxypropyl Methyl Cellulose ene-viscosity engaphezu kuka-100,000, kuyadingeka ukwandisa inani le-Hydroxypropyl Methyl Cellulose ukuze kwandiswe kakhulu izinga lokugcina amanzi.
Ekwakhiweni okuthile, umphumela wokugcina amanzi kwe-slurry ungalungiswa ngokwandisa noma ukunciphisa inani le-Hydroxypropyl Methyl Cellulose. Imikhiqizo yochungechunge lwe-Hydroxypropyl Methyl Cellulose ingaxazulula ngempumelelo inkinga yokugcina amanzi ngaphansi kokushisa okuphezulu. Ezinkathini zokushisa okuphezulu, ikakhulukazi ezindaweni ezishisayo nezomile kanye nokwakhiwa okunezingqimba ezincane ohlangothini olunelanga, i-hydroxypropyl methylcellulose esezingeni eliphezulu iyadingeka ukuthuthukisa ukugcina amanzi kwe-slurry.
I-Hydroxypropyl Methyl Cellulose esezingeni eliphezulu inokufana okuhle kakhulu. Amaqembu ayo e-Methoxy kanye ne-Hydroxypropoxy asatshalaliswa ngokulinganayo ku-cellulose molecular chain. Ingathuthukisa ama-athomu e-oxygen kuma-hydroxyl kanye ne-ether bonds. Amandla okuhlangana kwamanzi okwenza ama-hydrogen bonds aguqula amanzi akhululekile abe amanzi aboshwe, ngaleyo ndlela ilawula ngempumelelo ukuhwamuka kwamanzi okubangelwa isimo sezulu esishisa kakhulu futhi ifinyelele ukugcinwa kwamanzi okuphezulu.
Ikhwalithi ephezului-hydroxypropyl Methyl Celluloseingahlakazeka ngokulinganayo nangokuphumelelayo ku-samente mortar kanye nemikhiqizo esekelwe ku-gypsum, igoqe zonke izinhlayiya eziqinile, bese yakha ifilimu emanzi, futhi umswakama osesisekelweni uzokhishwa kancane kancane esikhathini eside. Kwenzeka ukusabela komswakama ngezinto ezingaphili ze-gelling, ngaleyo ndlela kuqinisekiswe amandla okubopha kanye namandla okucindezela kwezinto. Ngakho-ke, ekwakhiweni kwehlobo okushisa okuphezulu, ukuze kufezwe umphumela wokugcina amanzi, kuyadingeka ukwengeza imikhiqizo ye-Hydroxypropyl Methyl Cellulose esezingeni eliphezulu ngobuningi obanele ngokwefomula, ngaphandle kwalokho, kuzokwenzeka umswakama onganele, amandla ancishisiwe, kanye nokuqhekeka ngenxa yokomisa ngokweqile. Izinkinga zekhwalithi ezifana nokugoba, ukugoba kanye nokuwa nazo zandisa ubunzima bokwakha kwabasebenzi. Njengoba izinga lokushisa lehla, inani le-Hydroxypropyl Methyl Cellulose elingeziwe lingancishiswa kancane kancane, futhi umphumela ofanayo wokugcina amanzi ungafinyelelwa.
