Hydroxypropyl methylcellulose(HPMC) ke motsoako o feto-fetohang o sebelisoang haholo indastering e fapaneng, ho kenyeletsoa le indasteri ea kaho. Thepa ea eona e ikhethang e etsa hore e be motsoako oa bohlokoa lits'ebetsong tse fapaneng tsa kaho. Sehloohong sena, re tla hlahloba ts'ebeliso e arotsoeng ea hydroxypropyl methylcellulose indastering ea kaho, re totobatsa bohlokoa le melemo ea eona.
HPMC kepolymer e qhibilihang ka metsinge nkiloeng ho cellulose. E fumaneha hangata e le tharollo ea hydroxypropyl methylcellulose, e ka kopanngoang habonolo le metsi ho etsa ntho e kang gel. Tharollo ena e sebetsa e le sehokelo, se tenyang le se entsoeng ka filimi lits'ebetsong tsa kaho.
E 'ngoe ea tšebeliso ea mantlha ea hydroxypropyl methylcellulose indastering ea kaho ke ho fetola seretse le plaster. Ha e eketsoa thepa e thehiloeng samenteng, HPMC e ntlafatsa bokhoni ba tsona ba ho sebetsa, matla a sekhomaretsi le bokhoni ba ho boloka metsi. E sebetsa e le moemeli oa ho teteana, e fokotsa monyetla oa ho thekesela le ho ntlafatsa botsitso ka kakaretso ba motsoako. Sena se nolofalletsa basebetsi ba kaho ho sebelisa seretse kapa plaster hantle le ka ho lekana.
Tšebeliso e 'ngoe ea bohlokoa eaHPMCkahong e le sehokelo sa sekhomaretsi sa thaele. Ha e eketsoa ho likhomaretsi tsa thaele, HPMC e ntlafatsa matla a tsona a ho kopanya 'me e fana ka nako e ntle ea ho buleha, e leng se lumellang ho lokisoa habonolo ha sebaka sa thaele. E boetse e ntlafatsa litšobotsi tsa ho ata le ho kolobisa tsa sekhomaretsi, e netefatsa ho khomarela hantle holim'a substrate. Ho feta moo, HPMC e sebetsa e le colloid e sireletsang, e thibela ho oma pele ho nako ha sekhomaretsi le ho fokotsa ho thehoa ha mapetso.
Ntle le di-modifiers tsa seretse le di-glue tsa dithaele, hydroxypropyl methylcellulose e boetse e sebediswa haholo e le sehlomathiso sa motswako o iketsang. Metswako e iketsang e sebediswa ho fihlella dibaka tse boreleli le tse lekanang pele ho kenngwa dikobo tsa fatshe. HPMC e eketswa metswakong e iketsang ho ntlafatsa phallo ya yona le thepa ya ho iketsa. E ntlafatsa phallo ya motswako, e o dumella ho ata ha bonolo le ho iketsang boemong, e leng se fellang ka bokahodimo bo phethahetseng, bo bataletseng.
Ho feta moo,hydroxypropyl methylcellulosee bapala karolo ea bohlokoa ho thehoeng ha litsamaiso tsa ho kenya le ho qeta tsa kantle (EIFS) indastering ea kaho. EIFS ke litsamaiso tse nang le mekhahlelo e mengata tse sebelisetsoang ho kenya le ho khabisa mocheso. HPMC e sebelisoa karolong ea motheo le ea ho qetela ea EIFS ho ntlafatsa bokhoni ba tsona ba ho sebetsa, ho hanyetsa mapetso le ho khomarela substrate. E eketsa ho tenyetseha le ho tšoarella ha liphahlo, ho netefatsa ts'ebetso e tšoarellang nako e telele.
Qetellong, hydroxypropyl methylcellulose e na le lits'ebetso tse ngata indastering ea kaho. Bokhoni ba eona ba ho fetola li-mortar le li-plaster, ho ntlafatsa likhomaretsi tsa thaele, ho ntlafatsa metsoako e ikamahanyang le maemo, le ho matlafatsa EIFS e etsa hore e be motsoako oa bohlokoa haholo thepa ea kaho. Tšebeliso ea HPMC lits'ebetsong tsena e tlatsetsa ho sebetseng hantle, matla a eketsehileng a tlamo, litšobotsi tse ntlafetseng tsa ho folisa, le ho tšoarella ho matlafalitsoeng ha merero ea kaho. Ha indasteri ea kaho e ntse e tsoela pele ho fetoha, karolo ea hydroxypropyl methylcellulose e tla lula e le ea bohlokoa, e fana ka litharollo bakeng sa liphephetso tse fapaneng tse tobaneng le merero ea kaho.
