Hydroxypropyl methylcellulose (HPMC) e sebelisoa haholo ho putty-grade putty, haholo-holo ka lebaka la thepa ea eona e ikhethang ea 'mele le lik'hemik'hale. Karolo ea bohlokoa ea sehlahisoa sena sa ether ea cellulose indastering ea kaho e ke ke ea hlokomolohuoa, haholo-holo ka har'a mabota a putty formulations. Sengoliloeng sena se tla hlahisa ka ho qaqileng mokhoa oa ts'ebetso oa HPMC ka putty, ntlafatso ea ts'ebetso le melemo ea eona lits'ebetsong tse sebetsang.
1. Lintho tsa motheo tsa HPMC
HPMC (Hydroxypropyl Methylcellulose) ke nonionic cellulose ether e lokisitsoeng ho tsoa ho phetoho ea lik'hemik'hale ea cellulose ea tlhaho. Lihlopha tsa Methyl le hydroxypropyl li kenngoa ka har'a limolek'hule tsa eona, kahoo li ntlafatsa ho qhibiliha, ho tsitsa ha viscosity le lisebelisoa tse ling tsa 'mele le tsa lik'hemik'hale. Ntho e hlahelletseng ka ho fetisisa ea HPMC ke ho qhibiliha ha eona hantle ha metsi, e ka qhibilihang metsing a batang le a chesang ho etsa tharollo ea colloidal e hlakileng kapa e feto-fetohang. Ho phaella moo, e na le thepa e babatsehang ea ho etsa lifilimi, ho boloka metsi, ho teteaneng le ho ba le lubricity. Lintho tsena li etsa hore HPMC e be le karolo ea bohlokoa ho putty ea lebota.
2. Karolo e ka sehloohong ea HPMC ho putty ea lebota
Sesebelisoa sa ho boloka metsi
Wall putty, e le thepa ea ho tlatsa, hangata e hloka ho theha sebaka se bataletseng, se boreleli leboteng. E le ho finyella phello ena, thepa ea ho boloka mongobo ea putty e bohlokoa. HPMC e na le thepa e matla haholo ea ho boloka metsi 'me e ka thibela mongobo hore o se ke oa tsoa ka potlako nakong ea ho omisa. Kaha putty layer e nka nako ho tiisa kamora kopo, HPMC e ka liehisa sekhahla sa mouoane oa metsi mme ea netefatsa hore putty e na le metsi ka botlalo, e leng molemo ho ntlafatsa boleng ba kaho le ho thibela ho phatloha kapa phofshoana ea lebota.
phello e teteaneng
HPMC haholo-holo e sebetsa joalo ka motenya ka har'a putty. Phello e teteaneng e etsa hore putty e be le kaho e ntle le ho sebetsa hantle. Ka ho eketsa palo e nepahetseng ea HPMC, viscosity ea putty e ka eketsoa, ho nolofatsa ho aha. E boetse e ntlafatsa ho khomarela ha putty leboteng 'me e thibela putty hore e se ke ea sisinyeha kapa ea senyeha nakong ea kaho. Ho tsitsa ho nepahetseng ho boetse ho tiisa hore putty e boloka sephara se setle le ho ts'oana libakeng tse fapaneng tsa kaho.
Lubrication le thepa ea ho thella
HPMC e ka ntlafatsa haholo lubricity ea putty le ho ntlafatsa maikutlo a kaho. Nakong ea ts'ebetso ea ho kenya li-putty, basebetsi ba ka sebelisa putty ka ho lekana leboteng habonolo, ho fokotsa bothata ba ho haha. Ho feta moo, ho thella ho matlafalitsoeng ha putty ho ka ntlafatsa khanyetso ea eona le ho qoba tšenyo ea bokaholimo e bakoang ke likhohlano tsa morao-rao tsa kaho.
Thibela ho petsoha
Ka lebaka la ho boloka metsi le phello e matla ea HPMC, putty e ka lokolla metsi ka mokhoa o ts'oanang nakong ea ts'ebetso ea ho omisa, kahoo e qoba ho phunyeha ho bakoang ke ho omisa ho feteletseng sebakeng seo. Wall putty hangata e angoa habonolo ke liphetoho tikolohong ea kantle joalo ka mocheso le mongobo nakong ea kaho ea sebaka se seholo, athe HPMC e netefatsa bots'epehi ba putty layer ka phello ea eona ea taolo.
Ntlafatsa khanyetso ea sag
Nakong ea ts'ebetso ea kaho, haholo-holo bakeng sa marako a emeng, thepa ea putty e atisa ho oela kapa ho oa. Joaloka moemeli oa ho thibela metsi le ho boloka metsi, HPMC e ka eketsa ka katleho thepa ea ho khomarela le e khahlanong le sag ea putty, ho etsa bonnete ba hore putty e boloka botenya le sebōpeho se tsitsitseng ka mor'a ho hahoa.
Ho ntlafala ho hanyetsa ho apara le ho tšoarella
Ka thepa ea eona ea ho etsa lifilimi le ho tiisa, HPMC e ka theha lesela le ts'ireletso le ts'ireletso la putty kamora ho folisa, ho ntlafatsa ho hanyetsa ha eona le ho tšoarella. Sena se ke ke sa lelefatsa bophelo ba ts'ebeletso ea lebota feela, empa hape se ntlafatsa ho hanyetsa ha putty layer ho tikoloho e kantle, joalo ka ho hanyetsa boemo ba leholimo, ho kenella ha metsi, jj.
3. Melemo ea kopo ea HPMC ka putty ea lebota
Ho bonolo ho sebetsa
Kaha HPMC e ka ntlafatsa ts'ebetso ea kaho ea putty, tšebeliso ea HPMC putty e bonolo ho sebetsa ho feta putty ea setso. Basebeletsi ba ka qeta mosebetsi oa kopo ka potlako, 'me li-sags le li-bubble ha li khone ho etsahala nakong ea kaho, kahoo katleho ea kaho e ntlafala haholo. Ntle le moo, lubricity ea HPMC e boetse e lumella basebetsi ho fumana lesela le lengata le boreleli leboteng.
botsoalle ba tikoloho
HPMC ke thepa e baballang tikoloho e sebelisoang haholo lipenteng le li-putty tse thehiloeng metsing 'me ha e lokolle likhase tse kotsi kapa lik'hemik'hale. Tšobotsi ena e kopana le litlhoko tsa indasteri ea kaho ea morao-rao bakeng sa lisebelisoa tse sireletsang tikoloho 'me ha e na kotsi ho' mele oa motho, e leng se etsang hore e sebelisoe haholo ho khabisa ka hare.
Melemo ea moruo
Joalo ka tlatsetso e bolokang litšenyehelo, HPMC e theko e phahameng hanyane ho feta litekanyo tse ling tsa setso, empa tekanyetso ea eona ka putty e tlase, 'me hangata ho hlokahala chelete e nyane ho fihlela sephetho se lakatsehang. Ntle le moo, HPMC e ka ntlafatsa ts'ebetso ea kaho le boleng ba putty, ea fokotsa sekhahla sa ho sebetsa bocha, 'me ea ba le melemo e phahameng ea moruo ka nako e telele.
Ho feto-fetoha ha maemo
Ntle le ho bapala karolo ea ho boloka metsi, ho tenya, ho tlotsa le ho thibela ho senya ka har'a putty, HPMC e ka boela ea sebetsa le li-additives tse ling tse sebetsang ho ntlafatsa ts'ebetso e akaretsang ea putty. Ka mohlala, HPMC e ka sebelisoa hammoho le li-antifungal agents ho ntlafatsa thepa ea antifungal le antibacterial ea putty, e lumellang lerako hore le lule le le letle le le hloekile ka mor'a tšebeliso ea nako e telele.
4. Lintlha tse amang phello ea HPMC
Leha HPMC e sebetsa hantle ka putty, katleho ea eona e boetse e angoa ke lintlha tse ling tsa kantle. Pele ho tsohle, palo ea HPMC e kenyellelitsoeng e hloka ho lokisoa ka nepo ho latela foromo ea putty. Ho feteletseng kapa ho sa lekaneng ho tla ama ts'ebetso ea ho qetela ea putty. Taba ea bobeli, mocheso le mongobo le ona o tla ba le tšusumetso ts'ebetsong ea ho boloka metsi ea HPMC. Mocheso o feteletseng o ka etsa hore phello ea ho boloka metsi ea HPMC e fokotsehe. Ho phaella moo, boleng le boima ba limolek'hule tsa HPMC le tsona li na le tšusumetso e kholo ho phello e teteaneng le ts'ebetso ea ho etsa filimi ea putty. Ka hona, ha ho khethoa HPMC, ho tlameha ho nahanoa ka botlalo hammoho le litlhoko tse khethehileng tsa kopo.
Hydroxypropyl methylcellulose (HPMC), joalo ka setlatsetso se sebetsang ka bongata le se sebetsang hantle haholo, se bapala karolo ea bohlokoa ho putty ea lebota la boemo ba kaho. Ha e ntlafatse feela ts'ebetso ea ho sebetsa, ho hanyetsa ho phatloha le ho tšoarella ha putty, empa hape e ntlafatsa haholo boleng ba kakaretso ea putty ka ho ntlafatsa ho boloka metsi, ho teteaneng le lisebelisoa tse ling. Ha tlhoko ea indasteri ea kaho ea lisebelisoa tse baballang tikoloho le ts'ebetso e phahameng e ntse e eketseha, litebello tsa ts'ebeliso ea HPMC li tla pharalla.
