I-HPMC Hydroxypropyl methyl celluloseodakeni lukasimende kanye ne-gypsum slurry, ikakhulukazi idlala indima yokugcina amanzi nokuqina, ingathuthukisa ngempumelelo ukunamathela kanye nokumelana ne-slurry.
Izinga lokushisa lomoya, izinga lokushisa kanye nezinga lomfutho womoya lingathinta izinga lokuhwamuka kwamanzi odaka lukasimende kanye nemikhiqizo esekelwe ku-gypsum. Ngakho-ke ezinkathini ezihlukene zonyaka, ukwengeza i-hydroxypropyl methyl cellulose inani elifanayo lomphumela wokugcina amanzi womkhiqizo kunomehluko othile. Ekwakhiweni kukakhonkolo, umphumela wokugcina amanzi we-slurry ungalungiswa ngokwandisa noma ukwehlisa inani le-HPMC. Ukugcinwa kwamanzi kwe-methyl cellulose ether ezingeni lokushisa eliphezulu kuyinkomba ebalulekile yokuhlukanisa ikhwalithi ye-methyl cellulose ether.
Kuhle kakhului-hydroxypropyl methyl celluloseimikhiqizo yochungechunge ingaxazulula ngokuphumelelayo inkinga yokugcinwa kwamanzi ngaphansi kwezinga lokushisa eliphezulu. Esikhathini sokushisa okuphezulu, ikakhulukazi ezindaweni ezishisayo nezomile kanye nokwakhiwa kongqimba oluncane ohlangothini olushisayo, isidingo sekhwalithi ephezulu ye-HPMC yokuthuthukisa ukugcinwa kwamanzi okudaka; i-hydroxypropyl methyl cellulose (HPMC), ukufana kuhle kakhulu, kungamaqembu e-oksijini nomoya-mpilo we-hydroxypropyl asatshalaliswa ngokulinganayo eceleni kweketango le-cellulose, angathuthukisa umoya-mpilo we-hydroxyl kanye ne-ether kanye namanzi kukhiye ohlanganisa ikhono le-hydrogen bonding, enze amanzi mahhala we-hydration, ukuze ulawule ngempumelelo isimo sezulu esishisayo esibangelwa ukuhwamuka komswakama, Ukuzuza ukugcinwa kwamanzi okuphezulu.
Ikhwalithi ephezulu ye-hydroxypropyl methyl cellulose ingahlakaza ngokulinganayo nangempumelelo odakeni lukasimende nemikhiqizo kasimende, futhi ipakishe zonke izinhlayiya eziqinile, futhi yakhe ungqimba lwefilimu yokumanzisa, umswakama osesisekelweni isikhathi eside ukhululwa kancane kancane, kanye nokusabela kwe-hydration yezinto ezingaphili zikasimende. , ukuze kuqinisekiswe amandla esibopho namandla acindezelayo wezinto zokwakha.
Ekwakhiweni, ukuze kuzuzwe umphumela wokongiwa kwamanzi, kudingeka wengeze izinga eliphezuluI-HPMCimikhiqizo ngokuhambisana nefomula, ngaphandle kwalokho, kuzoba nokoma ngokushesha okukhulu okubangelwa ukungonelwa kwe-hydration, ukunciphisa amandla, ukuqhekeka, isigubhu esingenalutho kanye nezinkinga zekhwalithi zokuchitha, kodwa futhi kwandise ubunzima bokwakhiwa kwabasebenzi. Njengoba izinga lokushisa lincipha, inani lamanzi i-HPMC lingancishiswa kancane kancane, futhi umphumela ofanayo wokugcina amanzi ungafinyelelwa.
