Hydroxypropypropinyl Methylcelulo, HPMC) ke ntho e sebelisoang haholo indastering ea kaho, haholo-holo ka litlhahiso tsa matla. Polymer ea lekanyelitsoeng ea metsi e na le thepa e ngata, e e etsa motsoako o tloaelehileng likhariso, likarohano le lik'hemik'hale tse ling tsa kaho.
Selelekela ho Hydroxypropyl Methylcelllllulose (HPMC)
Hydroxypropypropypropinyl methylcelllulose (HPMC) ke manyolo a seng a na le chefo Ke moliba oa selefoui, polymer ea tlhaho e fumanoang lehong le thepa e 'ngoe ea limela. HPMC e fetotsoe ka tatellano ka ho eketsa li-hydroxxproPyL le lihlopha tsa methyl le thepa ea eona ea metsi, e matlafatsang le ho khatholla le ho khomarela.
HPMC ke polymer ea sa fetoheng e ka fuoang litlhokahalo tse ikhethang tsa sehlahisoa. E fumaneha litemaneng tse fapaneng, ho tloha ho tlase ho pono e phahameng, 'me e ka etsoa ka maemo a fapaneng a hydroxypropyl le methyl. Sena se lumella litsebi tsa lihlahisoa tsa lihlahisoa tsa tsona, li li etsa hore li be thata, ho ba bonolo ho li sebelisa le ho fokotsa theko e tlaase ho li hlahisa.
Melemo ea HPMC edheshes ea Tile
HPMC e sebelisoa haholo ka tatellano ea khatello ea maikutlo ka lebaka la melemo ea eona e mengata. Mona ke tse ling tsa Wena na HPMC ke polymer ea khetho ea ho khetha meriana ea Tile:
1. Ho boloka metsi
HPMC e ka monya le ho boloka metsi a mangata, e e etsa metsi a ntlafatsang a bolokang botsoalle ho Tile. Sena se bohlokoa hobane metsi a thusa ho eketsa ts'ebetso le ho o thibela ka substrate. Ka HPMC, Tile e tšoarellang e lula e sebetsa e telele, e fanang ka nako e eketsehileng ea ho sebelisa khabone le ho lokisa thaba pele e fihla.
2. Thickening
HPMC ke thipa e etsang hore litšōmo li be le likepe tse eketsehileng, tse thusang ho ntlafatsa matla a bona a matena. HPMC e tiisa ka khomareho ka ho leleka limolek'hule tsa metsi, tse khanyang 'me li theha karolo e sa fetoheng. Sena se etsa hore ho be bonolo ho sebelisa khomarela le ho fokotsa kotsi ea mapetso a molomo (ke hore ke ho lekanya pakeng tsa lithaelese).
3. Ntlafatsa ho latela moea
HPMC e ntlafatsa ho tšoareloa ha likhoebo tsa tale ka lebaka la mekhoa ea eona ea khang. Ha HPMC e theha filimi e tšesaane holim 'a substrate e thusang ho khomarela teraneng. Filimi eo e boetse e thibela ho rama ha ho omella ka ho sa feleng, ho etsa hore se lahleheloe ke matla.
4. Ho feto-fetoha le maemo
HPMC e ka etsa hore litšōmo e be kotsing ea ho fetoha le maemo khafetsa, tse bohlokoa libakeng tse tsamaeang khafetsa, joalo ka meahong e rarollang kapa e be litšisinyeho tsa lefatše kapa li hlasimollang. HPMC e thusa ho etsa hore e be e bohale haholo, e le hore e tsamaee ka matla le ho tsamaea le moaho, e fokotsa kotsi ea lithaelesa kapa u ikobela.
5. Thepa ea Anti-sag
HPMC e thusa ho fokotsa kotsi ea siile e khanyang ea lerako. Ka lebaka la thepa ea eona e matla, HPMC e thusa ho thibela khomarela ho thellisa kapa ho tlola leboteng pele e fihla leboteng pele e fihla. Sena se ka thusa baetsi ba ho kenya ts'ebetsong ea Tile e sa fetoheng le ho fokotsa tlhokahalo ea ntlafatso.
ha re phethela
HPMC ke polymer e feto-fetohang e fana ka melemo e mengata ea indasteri ea kaho, haholo-holo ka mekhoa e meng ea terene. Metsi a eona - ho boloka metsi, ho tiisa, ho tlama, thepa e tlamang le e nang le meeli e etsa hore e ikhethele har'a litsebi tsa kaho lefatšeng ka bophara. Ka ho sebelisa HPMC ho ea hantle litšobotsi tsa ts'ebetso tsa lidherese tsa lefutso, ho ka etsa hore ho be bonolo ho li sebelisa hantle, 'me ha ho na monyetla oa ho hloleha. Ha ho makatse, joale, HPMC ke karolo ea bohlokoa ea indasteri ea kajeno ea kaho.
