Hydroxypropyl Methyl Cellulose (HPMC) ke polymer e feto-fetohang e fumanang ts'ebeliso e pharaletseng lisebelisoa tse fapaneng tsa kaho ka lebaka la thepa ea eona e ikhethang. Sehlahisoa sena sa ether ea cellulose se nkiloe ho cellulose ea tlhaho 'me se sebelisoa haholo lihlahisoa tsa kaho bakeng sa bokhoni ba eona ba ho boloka metsi, ho a tiisa le ho a tlama.
1. Selelekela ho Hydroxypropyl Methyl Cellulose (HPMC)
Hydroxypropyl Methyl Cellulose ke ether ea cellulose e seng ea ionic e fumanoang ka ho phekola cellulose ea tlhaho ka propylene oxide le methyl chloride. E qhibiliha ka metsing 'me e etsa tharollo e bonaletsang, e tiileng. Tlhaho e feto-fetohang ea HPMC e hlaha ka lebaka la bokhoni ba eona ba ho fetola thepa ea rheological, ho boloka metsi le ho khomarela thepa ea kaho.
2. Likopo ka Mortar
2.1. Ho Boloka Metsi
HPMC e sebediswa haholo mefuteng ya seretse ho ntlafatsa ho boloka metsi. Tlhaho ya yona e ratang metsi e e dumella ho monya le ho boloka metsi, e thibela ho oma pele ho nako ha seretse. Thepa ena e netefatsa ho sebetsa hantle, nako e telele ya ho seta, le ho kgomarela ha di-substrate ho ntlafetseng.
2.2. Taolo ea ho Tetefala le Rheology
Ho eketsoa ha HPMC mefuteng ea seretse ho fana ka thepa e lakatsehang ea ho teteana, e susumetsang boitšoaro ba rheological ba motsoako. Sena se bohlokoa bakeng sa ho nolofatsa tšebeliso le ho fihlela botsitso bo lakatsehang seretseng.
2.3. Khomarelo e Ntlafetseng
Ho kenyelletsa HPMC ka har'a seretse ho ntlafatsa ho khomarela libakeng tse fapaneng, ho tlatsetsa matla le ho tšoarella ha thepa ea kaho ka kakaretso. Sena se bohlokoa haholo lits'ebetsong tse kang ho kenya lithaele tsa letsopa.
3. Litšebeliso ho Likhomaretsi tsa Lithaele le Li-Grout
3.1. Ho Sebetsa ho Ntlafalitsoeng
Hangata likhomaretsi tsa thaele li na le HPMC ho ntlafatsa ho sebetsa hantle le nako e bulehileng. Polima e etsa bonnete ba hore sekhomaretsi se lula se le boemong bo sebetsang ka nako e telele, e leng se lumellang ho beoa ha thaele hantle ntle le ho oma pele ho nako.
3.2. Ho Fokotseha ha ho Koaleha
HPMC e kenya letsoho ho theheng ha dikhomaretsi tsa dithaele tse thibelang ho thekesela. Sena se bohlokwa ha ho kenngwa dithaele hodima bokahodimo bo otlolohileng, kaha se thibela dithaele ho thella pele sekhomaretsi se seta.
3.3. Ho Hanela Mapetso ho Di-Grout
Mefuteng ea grout, HPMC e thusa ho thibela ho petsoha ka ho fana ka ho tenyetseha le ho fokotsa ho fokotseha. Sena se molemo haholo libakeng tseo ho tsona liphetoho tsa mocheso li ka amang thepa ea kaho.
4. Litšebeliso ho Plaster
4.1. Bokgoni bo Ntlafetseng ba ho Sebetsa le ho Ata
Hangata HPMC e eketsoa mefuteng ea plaster ho ntlafatsa ho sebetsa le ho hasana. Polima e thusa ho fihlella ts'ebeliso e boreleli le e tsitsitseng ea plaster holim'a libaka.
4.2. Khanyetso ea Mapetso
Jwalo ka karolo ya yona ho di-grout, HPMC e thusa ho hanela mapetso ka hara plaster. E etsa filimi e tenyetsehang e amohelang metsamao ya tlhaho ya thepa ya kaho, e fokotsang kgonahalo ya mapetso.
5. Litšebeliso ho Metsoako ea Boithati
5.1. Taolo ea Phallo
Metswakong e iketsang e lekantsoeng, HPMC e sebediswa ho laola phallo le thepa ya ho lekantswa. Polima e netefatsa kabo e tshwanang mme e thusa ho boloka botenya bo lakatsehang ba motsoako hodima bokahodimo ba kopo.
5.2. Khomarelo e Ntlafalitsoeng
HPMC e ntlafatsa ho khomarela ha metsoako e iketsang e lekantsoeng le li-substrate tse fapaneng, e leng se fanang ka tlamo e matla le e tšoarellang. Sena se bohlokoa bakeng sa ts'ebetso ea nako e telele ea bokaholimo bo lekantsoeng.
6. Qetello
Hydroxypropyl Methyl Cellulose e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso ea thepa e fapaneng ea kaho. Ts'ebeliso ea eona ho seretse, likhomaretsi tsa thaele, li-grout, plaster le metsoako e ikamahanyang e bontša ho tenyetseha le katleho ea eona indastering ea kaho. Litšobotsi tse ikhethang tsa HPMC, ho kenyeletsoa ho boloka metsi, ho teteana le ho ntlafala ha ho khomarela, li kenya letsoho boleng bohle, ho tšoarella le ho sebetsa ha thepa ena ea kaho. Ha indasteri ea kaho e ntse e tsoela pele ho fetoha, HPMC e ntse e le motsoako oa bohlokoa ho etseng thepa ea kaho e tsoetseng pele le e sebetsang hantle.
