HydroxypropitypropiypropinyLulose (HPMC) ke pherekano ea maiketsetso ea cellulose, polymer ea tlhaho e fumanehang marakong a lily. Ha Hpmc ka boyona ha se feela kang biopolymer hobane e ntse e sebelisoa ka makhetlo-tekano, hangata e nkoa e le li-biopolymers tse entsoeng ka mafometso kapa tse fetotsoeng.
A. Selelekela ho HydroxypropyL methylcell.
HydroxypropypropyLe Methylcelllulose (HPMC):
HydropxypropitypropitypropyLuloseth Celluloselese ke karolo ea mantlha ea marako a limela. HPMC e entsoe ka ho lekanya cellulose ka ho eketsa hydroxxxxxyl le lihlopha tsa methyl.
B. Tsamaiso le ts'ebetso:
1.Chemical sebopeho:
Sebopeho sa lik'hemik'hale sa HPMC se na le likarolo tsa litlokotsebe tsa mokokotlo tsa cellulose Degree of Singlution (DS) e bua ka palo ea hydroxypropyl le lihlopha tsa methyl ka li-glucose ka kemiso ea Glucose. Phetoho ena e fetola thepa ea lik'hemik'hale ea 'mele le ea lik'hemik'hale ea selefou, e bakang limaraka tse fapaneng tsa HPMC e nang le lipolaiti tse fapaneng, tsa solcolity.
Metsi a 2.physical:
SELLE: HPMC e qhibiliha ka metsing le mefuta e hlakileng, e e etsa motsoako oa bohlokoa ka mefuta e fapaneng ea lits'ebetso, lijo le kaho.
Viscosity: Visicosity ea tharollo ea HPMC e ka laoloa ka ho fetola boima ba polymer le moleng. Thepa ena e bohlokoa bakeng sa lits'ebetso tse kang liphallelo tsa meriana le lisebelisoa tsa kaho.
3. Ts'ebetso:
Li-thickeners: HPMC e sebelisoa e le thipa ka har'a thipa lijong, meriana le lihlahisoa tsa tlhokomelo ea motho.
Filimi e thehang: E ka theha lifilimi 'me e ka sebelisoa bakeng sa matlapa a phalleng le li-capsules, le tsa ho hlahisa lifilimi bakeng sa lits'ebeletso tse fapaneng.
Ho Boloka Metsi: HPMC e tsejoa ka thepa ea eona ea ho robala metsi, ho thusa ho ntlafatsa phaello le hydughtion ea thepa e thehiloeng ho thibela.
C. Kopo ea HPMC:
1. Lithethefatsi:
Letlapa la Letlapa: HPMC e sebelisetsoa ho etsa mabaka a matala ho laola ho lokolloa ha lithethefatsi le ho ntlafatsa botsitso.
Tlhahiso ea lithethefatsi ea molomo: Thepa ea ho lokolla le ho lokolloa ha tšoaetsa ho hlekefe ea HPMC e etsa hore e be loketse lits'ebetso tsa ho tlisa limpho tsa molomo.
Indasteri ea 2.
Lihlahisoa tsa seretse le samente: HPMC e sebelisoa ka lisebelisoa tsa kaho ho matlafatsa moea oa metsi, ho ikoetlisa le ho hlakoloa le ho hlakoloa.
3. Indasteri ea lijo:
Li-thickeners le ba thata: HPMC e sebelisoa e le thipa ebile e le thata lijong tsa ho ntlafatsa sebopeho le botsitso.
4. Lihlahisoa tsa tlhokomelo ea motho ka mong:
Sebopeho sa litlolo: HPMC e kenyelletsoa ka mekhoa ea boselamose le e matlafatsang.
5.Paints le likano:
Manahako a ho ba le metsi: Indastering ea Coatiings, HPMC e sebelisoa mefuteng ea boboto ho ntlafatsa Rheology le ho thibela ho lula ha eona.
6. Mehopolo ea tikoloho:
Ha HPM ka boyeng ha se polymer e phethoang ka mokhoa o nepahetseng HPMC can biodegrade under certain conditions, and its use in sustainable and biodegradable formulations is an area of ongoing research.
HydropxypropitypropiypropinyLulose (HPMC) ke polymer ea maiketsetso e nang le kelello e tsoang cellulose. Theo e ikhethang e etsa hore e be bohlokoa indasteri, ea kaho, ho ahoa, lijo, tlhokomelo ea botho le ho penta. Le ha e se mofuta o hloekileng ka ho fetisisa oa biopolymer le semelo sa eona sa contenwalose le monyetla oa biodegraba o ntse o tsamaisana le tlhokeho e matla ea lisebelisoa tse tsitsitseng tsa likopo tse fapaneng. Patlisiso e tsoelang pele e tsoela pele ho fumana mekhoa ea ho ntlafatsa ts'ehetso ea tikoloho ea HPMC ebe o eketsa ts'ebeliso ea eona.
