I-HPMC idlala kakhulu indima yokugcina amanzi kanye nokujiya odakeni lukasimende kanye nodaka olusekelwe ku-gypsum, olungathuthukisa 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, ukungeza 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 ngempumelelo 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 eceleni kweketango lamangqamuzana e-cellulose, elingathuthukisa ikhono lama-athomu omoya-mpilo ku-hydroxyl ne-ether bond ukuze ahlangane namanzi ukuze akhe izibopho ze-hydrogen, ukuze amanzi amahhala aba amanzi abophekile, ukuze alawule ngokuphumelelayo ukuhwamuka kwamanzi okubangelwa izinga lokushisa eliphezulu futhi kuzuzwe ukugcinwa kwamanzi aphezulu.
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 acindezelayo wento. Ngakho-ke, ekwakhiweni kwehlobo lokushisa eliphezulu, ukuze kuzuzwe umphumela wokugcina amanzi, kuyadingeka ukwengeza imikhiqizo yekhwalithi ephezulu ye-HPMC ngokusho kwefomula, ngaphandle kwalokho, kuyoba khona ukugeleza kwamanzi okwanele, ukunciphisa amandla, ukuqhekeka, ukugoba nokuwa. okubangelwa ukoma ngokushesha okukhulu. Kuphinde kwandise ubunzima bokwakha kubasebenzi. Njengoba izinga lokushisa lincipha, inani elingeziwe le-HPMC lingancishiswa kancane kancane, futhi umphumela ofanayo wokugcina amanzi ungafinyelelwa.
