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 ukhululwa 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.
