Hydroxypropyl methylcellulose (HPMC) ke thepa e sebelisoang haholo indastering ea kaho ka lebaka la thepa ea eona e ntle ea ho boloka metsi.Lits'ebetsong tsa kaho tse kang li-plaster tsa samente, li-plaster le li-adhesives tsa lithaele, ho boloka metsi ho bohlokoa bakeng sa ts'ebetso e nepahetseng le katleho.
E le e 'ngoe ea thepa ea bohlokoa ka ho fetisisa ea HPMC, ho boloka metsi ho amana ka ho toba le viscosity ea thepa.Ha HPMC e na le viscosity e phahameng, e ntlafatsa bokhoni ba eona ba ho boloka metsi.Thepa ena e etsa HPMC khetho e ratoang ea thepa bakeng sa litsebi tsa kaho le tsa kaho.
Ho boloka metsi ho bohlokoa kahong kaha ho netefatsa hore lisebelisoa tse sebelisoang li boloka botsitso le ha li omme.Ka mohlala, ka li-samente tse fetoletsoeng kapa li-plaster, ho boloka metsi ho thibela thepa hore e se ke ea phunyeha, e senya botšepehi ba moralo.Ka mokhoa o ts'oanang, ho lokisa lithaele, ho boloka metsi ho thusa ho netefatsa hore sekhomaretsi sa lithaele se tšoarella ka thata ho substrate.Lisebelisoa tsena kaofela li itšetlehile ka HPMC ho fana ka mokhoa o nepahetseng oa ho boloka metsi bakeng sa ts'ebetso e nepahetseng.
Ha HPMC e sebelisoa e le thepa ea kaho, e thusa ho laola boemo ba mongobo 'me e tiisa hore ha ho tahlehelo ea mongobo ka ho omisa pele ho nako.Sena se bohlokoa bakeng sa li-stucco kapa lits'ebetso, kaha thepa e omellang kapele haholo e ka peperana mme e ka baka tšenyo ea sebopeho.Bokhoni ba HPMC ba ho ntlafatsa ho bolokoa ha metsi bo thusa ho boloka boemo ba mongobo bo tsitsitseng nakong eohle ea ts'ebetso, ho lumella thepa hore e ome ka ho lekana ntle le ho baka tšenyo leha e le efe.
The viscosity e phahameng ea HPMC e fella ka tharollo e teteaneng, e thusang ho ntlafatsa thepa ea eona ea ho boloka metsi.Ho tsitsa ha HPMC ho tiisa hore thepa e lula e le holim'a metsi ka nako e telele, kahoo e boloka mongobo oa eona.Ho feta moo, ho tsitsa ho teteaneng ho liehisa mouoane, ho etsa bonnete ba hore thepa e omella butle le ka mokhoa o tsitsitseng bakeng sa pheletso ea boleng bo holimo.
Ntle le thepa ea eona e ntle ea ho boloka metsi, viscosity e phahameng ea HPMC e boetse e kenya letsoho ho sekhahla sa phallo ea eona, matla a tlamo le ts'ebetso.HPMC e phahameng ea viscosity e fana ka litekanyetso tse betere tsa phallo, ho etsa hore ho be bonolo ho hasana le ho sebetsana le bokaholimo bo alafshoang.High-viscosity HPMC e boetse e na le matla a sekhomaretsi a betere, a etsa hore e tlamahane ka thata ho substrate le ho ntlafatsa ts'ebetso ea kakaretso ea thepa.
Ha e sebelisoa lits'ebetsong tsa lithaele, HPMC e ntlafatsa ts'ebetso ea li-adhesives tsa lithaele, e etsa hore li se ke tsa sisinyeha haholoanyane, 'me li se ke tsa senyeha habonolo.Sena se bohlokoa haholo-holo libakeng tseo ho lebeletsoeng hore ho tsamaee meralo, joalo ka marokho, litsela tse kholo le lisebelisoa tse ling tsa sechaba.
HPMC ke thepa ea bohlokoa indastering ea kaho ka lebaka la thepa ea eona e ntle ea ho boloka metsi e lebisang pheletsong ea boleng bo holimo.Viscosity e phahameng ea HPMC e ntlafatsa thepa ea eona ea ho boloka metsi, sekhahla sa phallo, matla a tlamo le ts'ebetso ea ts'ebetso, e etsa hore e be e loketseng bakeng sa mefuta e fapaneng ea likopo indastering ea kaho, ho kenyeletsoa li-renders tsa samente, li-plaster le li-adhesives tsa lithaele.Ts'ebetso ea eona e phahameng ka ho fetisisa lits'ebetsong tsa meralo e tiisa hore meaho le meaho li tla ema ka nako e telele, ho matlafatsa polokeho, ts'ebetso le ho tšoarella ha tikoloho e hahiloeng.
