Ho ba le thepa e bohlokoa ka sekhukhung le likeleli, ho susumetsa likarolo tse fapaneng tsa merero ea kaho, ho kenyelletsa le ts'ebetso ea ts'ebeliso, le ts'ebetso ea ho qeta, le ts'ebetso ea nako. Ho fihlela ho ba le mosebetsi o mongata ho bohlokoa ho netefatsa liketso tse phethahetseng le sephetho se khotsofatsang. Hydroxypropypropypropinyl methylcelllulose (HPMC) e eketsoa ka bongata lisebelisoa tsa kaho ka lebaka la bokhoni ba eona ba ho ntlafatsa ho ntlafatsa.
1. Bohatsetso ba Hpmc:
HPMC ke sesebelisoa sa cellulose e tsoang ho khefu ea tlhaho. E fetotsoe ka lik'hemituli ka phapanyetsano ea ho fana ka thepa e ikhethang e loketseng likopo tse fapaneng, ho kenyelletsa le kaho. HPMC e tšoauoa ka bophahamo ba eona bo phahameng ka metsing, bokhoni ba tokiso, thepa e etsang lifilimi le ho se beha hantle lits'ebetsong tse thehiloeng metsing. Libaka tsena li etsa hore e be e 'nete bakeng sa ho ntlafatsa tšebetso ea likelello le libaka tsa polasetiki.
2. TLHOKOMELISO EA HO FIHLELA METSOALLE EA BOPHELO:
Ho eketsoa ha HPMC ho ea ho tšoantšetso le likotola li susumetsa lipehelo tsa bona tsa rheological, haholo-holo ka ho boloka metsi le tse matlafatsang. HPMC MOELCULES Etsisa filimi e sirelletsang ho pota-potiloe ke maemo a tšohanyetso, ho thibela tahlehelo ea metsi a potlakileng ka mouoane. Ts'ebetso ena e telele e ntlafalitse ho ntlafatsa ka motsoako, ho haella habonolo, ho hasana le ho se jala.
HPMC e sebetsa e le bolo ea thickener, e eketsa viscosity ea seretse kapa sahale. Phetoho ena ea pono e thusa ho laola kapa ho oela likopong, ka ho etsa joalo ho ntlafatsa tsitsipano le ho feto-fetoha ha thepa nakong ea kopo.
3.beofits of hpmc ka lepapa le likeleli:
Ho Ntlafatsa Lintho: HPMC e ntlafatsa ho ba le bofokoli le lijalo ka ho boloka litaba tse lekaneng le taolo ea li-viscoity, tse hlahisang kopo e matla le ho feta.
Tlhokahalo e Fosahetseng: Lihlopheng tsa ho Boloka Metsi a HPMC li fokotsa tlhokeho ea metsi a mang ka motsoako, e lebisang ho ntlafatsang ntle le ho tela matla kapa ho tšoarella.
Kholiseho e ntlafalitsoeng: Litšobotsi tse etsang lifilimi tsa lifilimi li khothalletsa ho felise ka theko e ntle pakeng tsa substrate le seretse kapa ho hlokahalla likotsi tsa ho lieha ho khaotsa.
Ho senya: ka ho matlafatsa ts'ebetso le tlhoko ea metsi, HPMC e thusa ho fokotsa shrinkage le li-placester ho phekola ts'ebetso ea nako e telele le ho tšoarella.
Ho fapanyetsana maikutlo: HPMC e ka sebelisoa ka mefuta le likepe tse fapaneng, ho kenyeletsoa le mekhoa e thehiloeng ho salemente le e etsang hore tekanyo e kenyeletsang lits'ebetsong tse fapaneng tsa kaho.
Litšireletso tsa 4.POSICA:
HPMC e kenyelletsoa ka tloaelo e kenngoeng ka mekhabiso ea seretse se seretse le mekhabiso ea bolulo, khoebo khoebong le kaho ea liindasteri. Litekanyetso tsa eona hangata li tloha ho 0,1% ho isa ho 0.5% ka boima ba lisebelisoa tsa mafetoheli, leha litlhokahalo tse khethehileng li ka fapana ka thepa le maemo a tikoloho.
Likopo tse ntle tse kang ho fana kapa li-hpmc li thusa ho ntlafatsa ho hanela mathata le ho fokotsa metsi a ho ntlafatsa. Likolong tse ka hare joalo ka ho koalla kapa ho koahela kapa skim, ho etsa hore ho be le moea o bonolo le ho tšelela ts'ebetso e ntle, ho ntlafatsa li-aesthetics tsa ho kenya le ho ntlafatsa li-aesthetics.
Hydroxypropypropinyl MethylceLulose Ka ho utloisisa mekhoa ea thepa ea eona ea ts'ebetso le ho kenya tšebetsong litekanyetso tse nepahetseng le mekhoa e nepahetseng, litsebi tsa kaho li ka ntlafatsa boleng le botsitso ba merero ea bona. Ha isosi ea kaho e ntse e tsoela pele ho fetoha, bohlokoa ba eketsang joalo ka hpmc ho fihlela ho ba le matla a phahameng le ts'ebetso e tla lula e le bohlokoa.
