I-HPMC idlala kakhulu indima yokugcina amanzi kanye nokujiya odakeni lukasimende kanye ne-gypsum-based slurry, engathuthukisa ngempumelelo ukuhlangana nokumelana nokucwila kwe-slurry.
Izinto ezifana nezinga lokushisa lomoya, izinga lokushisa kanye nomfutho womoya zizophazamisa izinga lokuhwamuka kwamanzi odaka lukasimende kanye nemikhiqizo eyenziwe ngegypsum. Ngakho-ke, ezinkathini ezihlukene zonyaka, ukwengeza inani elifanayo le-HPMC, umphumela wokugcina amanzi wemikhiqizo unomehluko othile. Ukugcinwa kwamanzi kwe-methyl cellulose ether ezingeni lokushisa eliphezulu kuyinkomba ebalulekile yokuhlukanisa ikhwalithi ye-methyl cellulose ether. I-HPMC enhle kakhulu ingaxazulula ngokuphumelelayo inkinga yokugcinwa kwamanzi ngaphansi kwezinga lokushisa eliphezulu. Ezikhathini zokushisa okuphezulu, ikakhulukazi ezindaweni ezishisayo nezomile kanye nokwakhiwa kongqimba oluncane ohlangothini olushisayo, i-HPMC yekhwalithi ephezulu iyadingeka ukuze kuthuthukiswe ukugcinwa kwamanzi odaka. Ikhwalithi ephezulu ye-HPMC, enokufana okuhle kakhulu, amaqembu ayo e-methoxy kanye ne-hydroxypropoxy asatshalaliswa ngokulinganayo eduze kweketango lamangqamuzana e-cellulose, elingathuthukisa ikhono lama-athomu oksijini ku-hydroxyl kanye nezibopho ze-ether ukuhlangana namanzi ukuze akhe izibopho ze-hydrogen, ukuze amanzi amahhala abe amanzi abophekile, ukuze alawule ngempumelelo ukuhwamuka kwamanzi okubangelwa ukuhwamuka okuphezulu kwamanzi okubangelwa ukuhwamuka kwamanzi aphezulu kanye nesimo sezulu esiphezulu.
Ikhwalithi ephezulu ye-cellulose HPMC ingahlakazwa ngokulinganayo nangempumelelo ku-cement mortar kanye nemikhiqizo esekelwe ku-gypsum, futhi ihlanganise zonke izinhlayiya eziqinile, futhi yakha ifilimu yokumanzisa, futhi umswakama osesisekelweni ukhishwa kancane kancane isikhathi eside. Ukusabela kwe-hydration kwe-coagulating material kwenzeka, ngaleyo ndlela kuqinisekiswe amandla okubopha kanye namandla okucindezela kwezinto. Ngakho-ke, ekwakhiweni kwehlobo lokushisa eliphezulu lokushisa, ukuze kuzuzwe umphumela wokugcinwa kwamanzi, kuyadingeka ukwengeza imikhiqizo ye-HPMC yekhwalithi ephezulu ngokusho kwefomula, ngaphandle kwalokho, kuyoba khona ukugeleza okwanele, ukunciphisa amandla, ukuqhekeka, ukugoba nokuwa okubangelwa ukomisa okusheshayo. Kuphinde kwandise ubunzima bokwakha kubasebenzi. Njengoba izinga lokushisa lincipha, inani elingeziwe le-HPMC lingancishiswa kancane kancane, futhi umphumela ofanayo wokugcina amanzi ungafinyelelwa.
