Hydroxypropyl methylcellulose(HPMC) ke komporo e feto-fetohang e sebelisoang haholo liindastering tse fapaneng, ho kenyeletsoa indasteri ea kaho.Thepa ea eona e ikhethang e etsa hore e be motsoako oa bohlokoa mefuteng e mengata ea kaho.Sehloohong sena, re tla hlahloba ts'ebeliso e arohaneng ea hydroxypropyl methylcellulose indastering ea kaho, re totobatsa bohlokoa ba eona le melemo ea eona.
HPMC kepolymer e qhibilihang ka metsie tsoang ho cellulose.Hangata e fumaneha e le tharollo ea hydroxypropyl methylcellulose, e ka kopanngoang habonolo le metsi ho etsa ntho e kang gel.Tharollo ena e sebetsa joalo ka setlamo, setenya, le filimi ea pele lits'ebetsong tsa kaho.
E 'ngoe ea litšebeliso tsa mantlha tsa hydroxypropyl methylcellulose indastering ea kaho ke sefetoleli sa seretse le samente.Ha e eketsoa ho thepa e thehiloeng ho samente, HPMC e ntlafatsa ts'ebetso ea bona, matla a sekhomaretsi, le bokhoni ba ho boloka metsi.E sebetsa e le ntho e teteaneng, e fokotsang monyetla oa ho fokotseha le ho ntlafatsa ho lumellana ka kakaretso ha motsoako.Sena se nolofalletsa basebetsi ba kaho ho tlotsa seretse kapa samente hantle le ka ho lekana.

Ho phaella ho li-modifiers tsa seretse le li-adhesives tsa lithaele, hydroxypropyl methylcellulose e boetse e sebelisoa haholo e le motsoako oa ho ikemela.Metsoako ea ho ikemela e sebelisetsoa ho finyella libaka tse boreleli esita le ho feta pele ho kenngoa likoahelo tsa fatše.HPMC e eketsoa ho metsoako ea ho ikemela ho ntlafatsa phallo ea bona le thepa ea bona.E ntlafatsa mokelikeli oa motsoako, o o lumella ho ata habonolo le ho itšehla thajana, ho fella ka sebaka se phethahetseng, se bataletseng.
Ho feta moo,hydroxypropyl methylcellulosee bapala karolo ea bohlokoa ho thehoeng ha litsamaiso tsa kantle tsa ho kenya le ho qeta (EIFS) indastering ea kaho.EIFS ke litsamaiso tse nang le mekhahlelo e mengata tse sebelisetsoang ho kenya mocheso le ho khabisa.HPMC e sebelisoa ka har'a seaparo sa motheo le seaparo sa ho qetela sa EIFS ho ntlafatsa ts'ebetso ea bona, ho hanyetsa ho phatloha, le ho khomarela substrate.E ntlafatsa ho tenyetseha le ho tšoarella ha liphahlo, ho netefatsa ts'ebetso ea nako e telele.
Qetellong, hydroxypropyl methylcellulose e na le lits'ebetso tse ngata indastering ea kaho.Bokhoni ba eona ba ho fetola lirafshoa le li-plaster, ho matlafatsa likhomaretsi tsa lithaele, ho ntlafatsa metsoako ea ho ikemela, le ho matlafatsa EIFS e etsa hore e be motsoako oa bohlokoa oa thepa ea kaho.Tšebeliso ea HPMC lits'ebetsong tsena e thusa ho sebetsa hantle, ho eketsa matla a bonto, litšoaneleho tse ntlafalitsoeng tsa ho folisa, le ho tšoarella ho matla ha merero ea kaho.Ha indasteri ea kaho e ntse e tsoela pele ho fetoha, karolo ea hydroxypropyl methylcellulose e tla lula e le bohlokoa, ho fana ka tharollo bakeng sa mathata a fapaneng a tobaneng le merero ea kaho.
