Hydroxypropyl methylcellulose (HPMC) ke cellulose ether e nkiloeng ho selulose ea tlhaho 'me e sebelisoa haholo indastering ea kaho ka lebaka la thepa ea eona e ikhethang le mefuta-futa. Ka thepa ea samente, HPMC e etsa mesebetsi e fapaneng, ho kenyelletsa ho ntlafatsa ts'ebetso, ho boloka metsi, ho khomarela le ho tšoarella.
1. Ntlafatsa ts'ebetso:
Ho sebetsa ke karolo ea bohlokoa ea konkreite le seretse, e amang mekhoa ea bona ea ho beha, ho kopanya le ho qeta. Li-additives tsa HPMC li bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso ka ho fokotsa litlhoko tsa metsi ha li ntse li boloka botsitso bo lakatsehang. Bokhoni bo phahameng ba ho boloka metsi ba HPMC bo eketsa ts'ebetso bakeng sa ho beoa hantle le ho phethoa ha motsoako oa konkreite le seretse. Ntle le moo, lisebelisoa tsa samente tse fetotsoeng tsa HPMC li bonts'a thepa e ntlafalitsoeng ea rheological, e nolofatsang ts'ebetso ea ho pompa le ho tšollela mererong ea kaho.
2. Ho boloka metsi:
Ho boloka metsi ho bohlokoa ho netefatsa hore ho na le metsi a lekaneng a lisebelisoa tsa samente, haholo-holo libakeng tse chesang kapa tse omileng moo tahlehelo ea mongobo e potlakileng e ka hlahang. Li-additives tsa HPMC li sebetsa e le lisebelisoa tse sebetsang tsa ho boloka metsi, ho thibela ho omisoa pele ho nako ha motsoako oa konkreite le seretse. HPMC e liehisa mouoane oa metsi ka ho etsa filimi e tšesaane ho pota-potile likaroloana tsa samente, ka tsela eo e lelefatsa ts'ebetso ea hydration le ho khothalletsa ntlafatso e nepahetseng ea matla. Tšobotsi ena e molemo ka ho khetheha libakeng tse nang le mocheso o phahameng kapa oa mongobo o tlase, moo ho boloka maemo a mongobo a lekaneng ho ka bang thata.
3. Ntlafatsa ho khomarela:
Tlamahano pakeng tsa thepa ea samente le substrate e bohlokoa bakeng sa ts'ebetso le nako e telele ea likarolo tsa mohaho tse kang li-adhesive tsa lithaele, li-plaster le li-plaster. Li-additives tsa HPMC li ntlafatsa ho khomarela ka ho matlafatsa matla a maqhama pakeng tsa bokaholimo ba thepa le sekhomaretsi kapa ho roala. Thepa ea ho etsa filimi ea HPMC e etsa mokoallo o ntlafatsang ho kopana pakeng tsa sekhomaretsi le substrate, e leng se hlahisang ts'ebetso e phahameng ea ho kopanya. Ho feta moo, HPMC e thusa ho fokotsa ho hlaha ha mapheo a honyehang, ka hona ho ntlafatsa ho tšoarella ha bokaholimo ba bokaholimo.
4. Ntlafatsa ho tšoarella nako e telele:
Ho tšoarella ke taba ea bohlokoa kahong, haholo meahong e pepesehileng maemo a thata a tikoloho kapa likhatello tsa mochini. Li-additives tsa HPMC li thusa ho ntlafatsa ho tšoarella ha lisebelisoa tsa samente ka ho eketsa ho hanyetsa ha tsona linthong tse kang li-cycles tsa leqhoa, tlhaselo ea lik'hemik'hale le abrasion. Ka ho ntlafatsa bokhoni ba ho sebetsa le ho fokotsa ho kenella ha metsi, HPMC e thusa ho fokotsa ho kenella ha lintho tse kotsi ka konkreite le seretse, kahoo e lelefatsa bophelo ba bona ba ts'ebeletso. Ho feta moo, lisebelisoa tse fetotsoeng tsa HPMC li bonts'a matla a matla a ho feto-fetoha le maemo, ka hona a ntlafatsa ts'ebetso ea sebopeho le ho tšoarella.
5. Melemo ea nts'etsopele ea moshoelella:
Ntle le melemo ea bona ea tekheniki, litlatsetso tsa HPMC li tlisa melemo e mengata ea ts'ebetso lekaleng la kaho. E le thepa e ka senyehang le e nchafalitsoeng e nkiloeng ho selulose, HPMC e thusa ho fokotsa tšusumetso ea tikoloho mesebetsing ea kaho. Ka ho ntlafatsa thepa ea thepa ea samente, HPMC e ka sebelisa dikahare tse tlase tsa samente motsoakong, ka hona, e fokotsa tlhahiso ea khabone e amanang le tlhahiso ea samente. Ntle le moo, HPMC e matlafalitse lirekere le konkreite li thusa ho ntlafatsa ts'ebetso ea matla ea meaho ka ho ntlafatsa thepa ea ho kenya mocheso le ho fokotsa tlhoko ea ho futhumatsa le ho pholisa ka maiketsetso.
6. Litebello:
Tlhokahalo ea lisebelisoa le mekhoa ea moaho e tsitsitseng e ntse e hola, e ntse e tsoela pele ho nts'etsapele lits'ebetso tsa ntlafatso ea li-additives tse baballang tikoloho joalo ka HPMC. Bokamoso ba HPMC indastering ea kaho bo khanya haholo, 'me lipatlisiso tsa hajoale li shebane le ho ntlafatsa ts'ebetso ea eona le ho holisa lits'ebetso tsa eona. Ntle le moo, tsoelo-pele ea lits'ebetso tsa tlhahiso le thekenoloji ea tlhahiso e lebelletsoe ho ntlafatsa ts'ebetso le katleho ea li-additives tsa HPMC, e leng ho etsang hore ho ata ha tsona mererong ea kaho lefats'eng ka bophara ho eketsehe.
Li-additives tsa Hydroxypropyl methylcellulose (HPMC) li bapala karolo ea bohlokoa ho ntlafatseng thepa le ts'ebetso ea lisebelisoa tsa samente lits'ebetsong tsa kaho. Ho tloha ka mokhoa o ntlafetseng oa ho haha le ho boloka metsi ho ea ho ho khomarela ho matlafatsang le ho tšoarella, HPMC e fana ka mefuta e mengata ea melemo e thusang ho ntlafatsa boleng, ts'ebetso le bophelo bo bolelele ba tikoloho e hahiloeng. Ha indasteri ea kaho e ntse e tsoela pele ho etelletsa pele botsitso le boqapi, HPMC e lebelletsoe ho tsoela pele ho ba motsoako oa bohlokoa ntlafatsong ea lisebelisoa tsa kaho tse sebetsang hantle, tse baballang tikoloho.
