Hydroxypropyl Methyl Cellulose (HPMC) ke polymer e feto-fetohang e fumanang lits'ebetso tse pharalletseng lisebelisoa tse fapaneng tsa moaho ka lebaka la thepa ea eona e ikhethang. Sehlahisoa sena sa cellulose ether se nkiloe ho selulose ea tlhaho 'me se sebelisoa haholo lihlahisoa tsa kaho bakeng sa ho boloka metsi, ho teteaneng le ho tlama.
1. Selelekela sa Hydroxypropyl Methyl Cellulose (HPMC)
Hydroxypropyl Methyl Cellulose ke ether e seng ea ionic cellulose e fumanoang ka ho phekola cellulose ea tlhaho ka propylene oxide le methyl chloride. E qhibiliha ka metsing 'me e etsa tharollo e hlakileng, ea viscous. Sebopeho se feto-fetohang sa HPMC se hlahisoa ke bokhoni ba eona ba ho fetola thepa ea rheological, ho boloka metsi, le ho khomarela thepa ea kaho.
2. Likopo ho Mortar
2.1. Polokelo ea Metsi
HPMC e atisa ho sebelisoa mefuteng ea seretse ho ntlafatsa ho boloka metsi. Sebopeho sa eona sa hydrophilic se e lumella ho monya le ho boloka metsi, ho thibela ho omisoa pele ho nako ea seretse. Thepa ena e netefatsa ts'ebetso e betere, nako e telele ea ho beha, le ho khomarela ho ntlafalitsoeng ho li-substrates.
2.2. Thickening le Rheology Taolo
Ho eketsoa ha HPMC mefuteng ea seretse ho fana ka thepa e lakatsehang e teteaneng, e susumetsang boitšoaro ba rheological ea motsoako. Sena se bohlokoa bakeng sa ho sebelisa habonolo le ho fihlela tumellano e lakatsehang ka har'a seretse.
2.3. Ntlafatso ea ho khomarela
Ho kenyelletsa HPMC ka seretse ho ntlafatsa ho khomarela libaka tse fapaneng, ho kenya letsoho ho matla le ho tšoarella ha thepa ea kaho. Sena se bohlokoa haholo lits'ebetsong tse joalo ka ho kenya lithaele tsa ceramic.
3. Likopo ho Li-Tile Adhesives le Grouts
3.1. Ntlafatso ea ho sebetsa
Likhomaretsi tsa lithaele hangata li na le HPMC ho ntlafatsa ts'ebetso le nako e bulehileng. Polymer e etsa bonnete ba hore sekhomaretsi se lula se le boemong bo sebetsang ka nako e telele, se lumellang hore ho behoe lithaele hantle ntle le ho omisa pele ho nako.
3.2. Ho fokotsa ho sisinyeha
HPMC e kenya letsoho ho li-anti-sagging properties tsa li-adhesives tsa lithaele. Sena se bohlokoa ha o kenya lithaele sebakeng se otlolohileng, kaha se thibela lithaele hore li se thellehe pele sekhomaretsi se seta.
3.3. Crack Resistance ho Grouts
Ho li-grout formulations, HPMC e thusa ho thibela ho phunyeha ka ho fana ka bonolo le ho fokotsa ho fokotseha. Sena se molemo ka ho khetheha libakeng tseo ho tsona ho fetoha ha mocheso ho ka amang thepa ea mohaho.
4. Likopo ka Plaster
4.1. Ntlafatso ea ho sebetsa le ho hasana
HPMC e atisa ho eketsoa ho libopeho tsa samente ho matlafatsa ts'ebetso le ho ata. Polymer e thusa ho etsa ts'ebetso e bonolo le e tsitsitseng ea samente holim'a bokaholimo.
4.2. Crack Resistance
Joalo ka karolo ea eona ho li-grouts, HPMC e kenya letsoho ho hanyetsang mapheo ka plaster. E etsa filimi e tenyetsehang e amohelang metsamao ea tlhaho ea thepa ea kaho, e fokotsang monyetla oa ho phatloha.
5. Likopo ho Metsoako ea Boiketlo ba Boiketlo
5.1. Taolo ea Phallo
Metsoakong ea ho ikemela, HPMC e sebelisoa ho laola phallo le thepa ea maemo. Polymer e netefatsa kabo e ts'oanang mme e thusa ho boloka botenya bo lakatsehang ba motsoako ho pholletsa le bokaholimo ba kopo.
5.2. Matlafatso a Matlafatsoa
HPMC e matlafatsa khokahanyo ea metsoako ea ho ikemela ho li-substrates tse fapaneng, e fana ka tlamo e matla le e tšoarellang. Sena ke sa bohlokoa bakeng sa ts'ebetso ea nako e telele ea sebaka se lekantsoeng.
6. Qetello
Hydroxypropyl Methyl Cellulose e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso ea lisebelisoa tse fapaneng tsa moaho. Tšebeliso ea eona ho seretse, likhomaretsi tsa lithaele, li-grouts, plaster, le metsoako ea ho ikemela e bonts'a ho feto-fetoha ha eona le katleho ea eona indastering ea kaho. Thepa e ikhethang ea HPMC, ho kenyelletsa ho boloka metsi, ho teteana, le ho khomarela ho ntlafalitsoeng, e kenya letsoho boleng ba kakaretso, ho tšoarella le ho sebetsa ha thepa ena ea moaho. Ha indasteri ea kaho e ntse e tsoela pele ho fetoha, HPMC e ntse e le motsoako oa bohlokoa ho thehoeng ha thepa ea moaho e tsoetseng pele le e sebetsang hantle.
