1. HPMC e arotsoe ka mofuta oa hang-hang le mofuta oa ho hasana ka potlako
Mofuta oa ho hasana ka potlako oa HPMC o kentsoe tlhaku S, 'me glyoxal e tlameha ho eketsoa nakong ea ts'ebetso ea tlhahiso.
Mofuta oa hang-hang oa HPMC ha o kenye litlhaku, joalo ka "100000" e bolela "100000 viscosity fast dispersion type HPMC".
2. Ka kapa ntle le S, litšobotsi li fapane
HPMC e hasaneng ka potlako e qhalana ka potlako ha e kopana le metsi a batang ebe e nyamela ka metsing.Ka nako ena, mokelikeli ha o na viscosity, hobane HPMC e qhalakanngoa feela metsing ntle le ho qhibiliha ha sebele.Kamora metsotso e ka bang peli, viscosity ea mokelikeli e ntse e eketseha butle-butle, e etsa "viscous" e hlakileng ea "Thick colloid".
Instant HPMC e ka qhalakanngoa ka potlako metsing a chesang a ka bang 70°C.Ha mocheso o theohela mocheso o itseng, viscosity e tla hlaha butle-butle ho fihlela ho thehoa li-viscous colloid tse hlakileng.
3. Ka kapa ntle le S, morero o fapane
Instant HPMC e ka sebelisoa feela ka putty powder le seretse.Ka sekhomaretsi sa metsi, pente le lihlahisoa tsa ho hlatsoa, ho tla ba le ts'ebetso ea lihlopha 'me e ke ke ea sebelisoa.
HPMC e hasantsoeng ka potlako e na le lits'ebetso tse fapaneng mme e ka sebelisoa ka phofo ea putty, seretse, sekhomaretsi sa metsi, pente le lihlahisoa tsa ho hlatsoa ntle le li-contraindication.
Mokhoa oa ho qhala
1. Nka tekanyo e hlokahalang ea metsi a chesang, e kenye ka har'a setshelo 'me ue chese ka holimo ho 80 ° C,' me butle-butle u kenye sehlahisoa sena tlas'a ho sisinyeha butle-butle.Selulose e phaphamala ka holim'a metsi qalong, empa butle-butle e qhalakanngoa ho etsa seretse se tšoanang.Tharollo e ne e pholile ha e ntse e hlohlelletsa.
2. Ntle le moo, futhumatsa 1/3 kapa 2/3 ea metsi a chesang ho feta 85 ° C, eketsa selulose ho fumana slurry ea metsi a chesang, ebe u eketsa metsi a batang a setseng, u tsoele pele ho hlohlelletsa, 'me u pholile motsoako o hlahisoang.
3. Mesh ea selulose e batla e le ntle, 'me e teng e le likaroloana tse nyenyane ka bomong ka phofo e ts'oanang e ts'oaretsoeng,' me e qhibiliha ka potlako ha e kopana le metsi ho etsa viscosity e hlokahalang.
4. Butle-butle le ka mokhoa o ts'oanang eketsa cellulose mocheso oa motsoako, o hlohlelletsa ka ho tsoelang pele ho fihlela ho thehoa tharollo e hlakileng.
Ke lintlha life tse amang ho bolokoa ha metsi a hydroxypropyl methylcellulose?
Ho boloka metsi a hydroxypropyl methylcellulose HPMC sehlahisoa ka bosona hangata ho angoa ke lintlha tse latelang:
1. Ho tšoana ha cellulose ether HPMC
HPMC e sebetsang ka ho lekana, methoxyl le hydroxypropoxyl li ajoa ka ho lekana, 'me sekhahla sa ho boloka metsi se holimo.
2. Thermal gelation mocheso oa cellulose ether HPMC
Ha mocheso oa gel o futhumatsang o phahame, sekhahla sa ho boloka metsi se phahame;ho seng joalo, sekhahla sa ho boloka metsi se ka tlase.
3. Cellulose ether HPMC viscosity
Ha viscosity ea HPMC e eketseha, tekanyo ea ho boloka metsi e boetse e eketseha;ha viscosity e fihla boemong bo itseng, ho eketseha ha sekhahla sa ho boloka metsi ho atisa ho ba sephara.
Keketso ea palo ea cellulose ether HPMC
Ha palo e kholo ea cellulose ether HPMC e eketsoa, sekhahla sa ho boloka metsi se phahame le phello e ntle ea ho boloka metsi.
Ho phaella ho 0.25-0.6%, tekanyo ea ho boloka metsi e eketseha ka potlako ka keketseho ea palo ea ho eketsa;ha palo ea tlatsetso e ntse e eketseha, mokhoa oa ho eketseha oa sekhahla sa ho boloka metsi oa fokotseha.
