Mokhoa oa ho sebelisa hydroxypropyl methylcellulose le litemoso

1. Kenyelletso ea hydroxypropyl methylcellulose

Hydroxypropyl methylcellulose (HPMC)ke non-ionic cellulose ether e entsoeng ka thepa ea tlhaho ea polymer ka phetoho ea lik'hemik'hale. E sebelisoa haholo kahong, meriana, lijo, litlolo, litlolo le masimo a mang, 'me e na le mesebetsi e mengata e kang ho teteaneng, ho boloka metsi, ho etsa lifilimi le ho khomarela.

2. Mokhoa oa ho sebelisa hydroxypropyl methylcellulose

Ho qhibiliha ha metsi a batang
AnxinCel®HPMC e ka qhalakanngoa ka ho toba metsing a batang, empa ka lebaka la hydrophilicity ea eona, ho bonolo ho etsa maqhubu. Ho kgothaletswa ho fafatsa HPMC butle-butle ka metsing a batang a tsositsoeng ho etsa bonnete ba ho hasana ho tšoanang le ho qoba ho kopana.

Ho qhibiliha ha metsi a chesang
Ka mor'a ho kolobisa HPMC pele ho metsi a chesang, eketsa metsi a batang ho e ruruha ho etsa tharollo e tšoanang. Mokhoa ona o loketse HPMC e nang le viscosity e phahameng.

Ho kopanya phofo e ommeng
Pele o sebelisa HPMC, e ka tsoakoa ka mokhoa o ts'oanang le lisebelisoa tse ling tse tala, ebe e hlohlelletsa ebe e qhibiliha ka metsi.

Indasteri ea kaho
Ka seretse le phofo ea putty, palo ea tlatsetso ea HPMC ka kakaretso ke 0.1% ~ 0.5%, e sebelisoang haholo ho ntlafatsa ho boloka metsi, ts'ebetso ea kaho le ts'ebetso ea anti-sagging.

Indasteri ea meriana
HPMC hangata e sebelisoa ho roala letlapa le matrix a tokollo e tsitsitseng, 'me litekanyetso tsa eona li lokela ho fetoloa ho latela foromo e ikhethileng.

Indasteri ea lijo
Ha e sebelisoa e le motenya kapa emulsifier lijong, litekanyetso li tlameha ho lumellana le litekanyetso tsa polokeho ea lijo, hangata 0.1% ~ 1%.

Liaparo
Ha HPMC e sebelisoa ka liphahlo tse thehiloeng metsing, e ka ntlafatsa ho tiea le ho qhalana ha lesela le ho thibela pula ea pigment.

Litlolo
HPMC e sebelisoa e le stabilizer ho litlolo ho ntlafatsa ho ama le ductility ea sehlahisoa.

3. Litlhokomelo tsa ho sebelisa hydroxypropyl methylcellulose

Nako ea ho qhala le taolo ea mocheso
HPMC e nka nako e itseng ho qhala, hangata metsotso e 30 ho isa ho lihora tse 2. Mocheso o phahameng haholo kapa o tlase haholo o tla ama sekhahla sa ho qhibiliha, 'me mocheso o loketseng le maemo a susumetsang a lokela ho khethoa ho ea ka boemo bo itseng.

Qoba agglomeration
Ha o eketsa HPMC, e lokela ho qhalakanngoa butle-butle le ho tsosoa ka botlalo ho thibela agglomeration. Haeba agglomeration e etsahala, e hloka ho tloheloa nako e itseng ebe e tsosoa ka mor'a hore e ruruhe ka ho feletseng.

Tšusumetso ea mongobo oa tikoloho
HPMC e na le kutloelo-bohloko ho mongobo 'me e atisa ho monya mongobo le ho kopana sebakeng sa mongobo o phahameng. Ka hona, tlhokomelo e lokela ho lefshoa ho omella ha tikoloho ea polokelo mme sephutheloana se lokela ho koaloa.

Ho hanyetsa acid le alkali
HPMC e batla e tsitsitse ho li-acids le alkalis, empa e ka senyeha libakeng tse matla tsa asiti kapa alkali, e amang ts'ebetso ea eona. Ka hona, maemo a feteletseng a pH a lokela ho qojoa ka hohle kamoo ho ka khonehang nakong ea tšebeliso. 

Khetho ea mefuta e fapaneng
HPMC e na le mefuta e fapaneng ea mehlala (e kang viscosity e phahameng, viscosity e tlaase, ho qhibiliha ka potlako, joalo-joalo), 'me ts'ebetso ea bona le ts'ebeliso ea tsona li fapane. Ha u khetha, mohlala o nepahetseng o lokela ho khethoa ho ea ka boemo bo khethehileng ba kopo (joaloka thepa ea mohaho, meriana, joalo-joalo) le litlhoko.

Bohloeki le polokeho
Ha o sebelisa AnxinCel®HPMC, lisebelisoa tsa ts'ireletso li lokela ho apesoa ho qoba ho hema lerōle.

Ha e sebelisoa lijong le meriana, e tlameha ho latela melao le maemo a indasteri e amehang.

Ho lumellana le li-additives tse ling

Ha e kopantsoe le lisebelisoa tse ling ka foromo, ho lokela ho lefshoa ho tsamaellana ha eona ho qoba pula, coagulation kapa litlamorao tse ling tse mpe.

4. Polokelo le lipalangoang

Polokelo
HPMCe lokela ho bolokoa sebakeng se phodileng, se omeletseng, ho qoba mocheso o phahameng le mongobo. Lihlahisoa tse sa sebelisoeng li hloka ho koaloa.

Lipalangoang
Nakong ea lipalangoang, e lokela ho sireletsoa ho pula, mongobo le mocheso o phahameng ho qoba tšenyo ea liphutheloana.

Hydroxypropyl methylcellulose ke lisebelisoa tsa lik'hemik'hale tse feto-fetohang tse hlokang ho senyeha ha saense le ho utloahalang, ho eketsoa le ho boloka lits'ebetsong tse sebetsang. Ela hloko ho qoba agglomeration, laola maemo a ho qhibiliha, 'me u khethe mohlala o nepahetseng le litekanyetso ho latela maemo a fapaneng a kopo ho eketsa ts'ebetso ea ona. Ka nako e ts'oanang, litekanyetso tsa indasteri li lokela ho lateloa ka thata ho netefatsa ts'ebeliso e bolokehileng le e sebetsang ea HPMC.
