I-HPMC Hydroxypropyl methyl celluloseku-samente mortar kanye ne-gypsum slurry, ikakhulukazi zidlala indima yokugcina amanzi kanye nokuqina, zingathuthukisa ngempumelelo ukunamathela kanye nokumelana nokuwa kwe-slurry.
Izinga lokushisa lomoya, izinga lokushisa kanye nengcindezi yomoya kungathinta izinga lokuhwamuka kwamanzi emikhiqizweni yesamente kanye nemikhiqizo esekelwe ku-gypsum. Ngakho-ke ezinkathini ezahlukene, ukwengeza i-hydroxypropyl methyl cellulose inani elifanayo lomphumela wokugcina amanzi womkhiqizo kunomehluko othile. Ekwakhiweni kwekhonkrithi, umphumela wokugcina amanzi we-slurry ungalungiswa ngokwandisa noma ukunciphisa inani le-HPMC. Ukugcinwa kwamanzi kwe-methyl cellulose ether ekushiseni okuphezulu kuyinkomba ebalulekile yokuhlukanisa ikhwalithi ye-methyl cellulose ether.
Kuhle kakhului-hydroxypropyl methyl celluloseimikhiqizo yochungechunge ingaxazulula ngempumelelo inkinga yokugcina amanzi ngaphansi kokushisa okuphezulu. Esikhathini sokushisa okuphezulu, ikakhulukazi ezindaweni ezishisayo nezomile kanye nokwakhiwa kwezingqimba ezincane ohlangothini olunelanga, isidingo se-HPMC esezingeni eliphezulu ukuthuthukisa ukugcinwa kwamanzi kwe-slurry; i-hydroxypropyl methyl cellulose (HPMC), ukufana kuhle kakhulu, iyiqembu le-hydroxypropyl ye-oxygen ne-oxygen elisatshalaliswa ngokulinganayo eceleni kwe-cellulose chain, ingathuthukisa i-hydroxyl ne-ether oxygen namanzi ku-key associate form bonding ability, yenze amanzi akhululekile, ukuze ilawule ngempumelelo isimo sezulu esishisayo esibangelwa umswakama ukuhwamuka, ifinyelele ukugcinwa kwamanzi okuphezulu.
Ikhwalithi ephezulu ye-hydroxypropyl methyl cellulose ingasakazeka ngokulinganayo nangokuphumelelayo emikhiqizweni ye-cement mortar kanye ne-plaster, futhi ipakishe zonke izinhlayiya eziqinile, futhi yakhe ungqimba lwefilimu yokumanzisa, umswakama osesisekelweni isikhathi eside ukhishwa kancane kancane, kanye nokusabela kokumanzisa kwezinto ezingaphili, ukuze kuqinisekiswe amandla okubopha kanye namandla okucindezela kwezinto.
Ekwakhiweni, ukuze kufezwe umphumela wokongiwa kwamanzi, kudingeka ukwengeza ikhwalithi ephezuluI-HPMCimikhiqizo ngokuvumelana nefomula, ngaphandle kwalokho, kuzoba nokomisa ngokushesha okukhulu okubangelwa ukunganeli kwamanzi, ukuncipha kwamandla, ukuqhekeka, izinkinga zedrama engenalutho kanye nokuphuma kwekhwalithi, kodwa futhi kwandisa ubunzima bezisebenzi zokwakha. Njengoba izinga lokushisa lehla, inani lamanzi i-HPMC lingancishiswa kancane kancane, futhi umphumela ofanayo wokugcina amanzi ungafinyelelwa.
