1. Sepheo sa mantlha sa hydroxypropyl methyl cellulose (HPMC) ke sefe?
HPMC e sebelisoa haholo ka thepa ea kaho, liphahlo, lirekere tsa maiketsetso, lirafshoa, meriana, lijo, masela, temo, litlolo, koae le liindasteri tse ling.
HPMC e ka aroloa ka sehlopha sa kaho, kereiti ea lijo le kereiti ea bongaka ho latela morero oa eona.
Hona joale, lihlahisoa tse ngata tsa malapeng ke tsa boemo ba kaho.Sebakeng sa kaho, phofo ea putty e sebelisoa ka bongata, hoo e ka bang 90% e sebelisetsoa putty powder, 'me e setseng e sebelisetsoa seretse sa samente le sekhomaretsi.
2. Ho na le mefuta e 'maloa ea hydroxypropyl methyl cellulose (HPMC).Phapano ke efe lipakeng tsa tšebeliso ea tsona?
HPMC e ka aroloa ka mofuta oa hang-hang le mofuta o chesang oa ho qhibiliha.
Sehlahisoa sa hang-hang se qhalana ka potlako metsing a batang 'me se nyamela ka metsing.Ka nako ena, mokelikeli ha o na viscosity, hobane HPMC e qhalakanngoa ka metsing 'me ha e hlile ha e qhibilihe.Hoo e ka bang metsotso e 2, viscosity ea mokelikeli e ile ea eketseha butle-butle, ea etsa colloid e hlakileng ea viscous.
Mofuta oa hang-hang, mefuta e mengata ea lisebelisoa, e ka sebelisoa ka putty powder le seretse, hammoho le ka sekhomaretsi sa metsi le pente.
Sehlahisoa se chesang se chesang, ha se kopana le metsi a batang, se ka qhalana ka potlako metsing a chesang 'me sa nyamela metsing a chesang.Ha mocheso o theohela mocheso o itseng, viscosity e bonahala butle-butle ho fihlela ho thehoa li-viscous colloid tse hlakileng.
Mofuta oa ho qhibiliha o chesang o ka sebelisoa feela ka phofo ea putty le seretse.

Mokhoa oa ho qhibiliha ha metsi a chesang: Kaha HPMC ha e qhibilihe metsing a chesang, HPMC e ka qhalakanngoa ka mokhoa o ts'oanang metsing a chesang qalong, ebe e qhibiliha ka potlako ha e pholile.Mekhoa e 'meli e tloaelehileng e hlalosoa ka tsela e latelang:
(1) Kenya selekanyo se se tlhokegang sa metsi a a molelo mo setshelong mme o se bese mo e ka nnang 70°C.Butle-butle eketsa hydroxypropyl methylcellulose ka ho sisinyeha butle, qala HPMC e phaphametse holim'a metsi, 'me butle-butle u thehe seretse,' me u pholisoe slurry ka ho sisinyeha.
(2).Kenya 1/3 kapa 2/3 ea palo e hlokahalang ea metsi ka har'a sets'oants'o ebe o se futhumatsa ho 70 ° C.Ho ea ka mokhoa o ka holimo, qhala HPMC ho lokisetsa slurry ea metsi a chesang;ebe o eketsa palo e setseng ea metsi a batang ho slurry ea metsi a chesang.Ka slurry, pholisa motsoako ka mor'a ho hlohlelletsa.
Mokhoa oa ho kopanya phofo: Kopanya phofo ea HPMC le lisebelisoa tse ling tse ngata tsa phofo ka motsoako, ebe u eketsa metsi ho qhibiliha, ebe HPMC e ka qhibiliha ka nako ena ntle le ho phunya, hobane sekhutlo se seng le se seng se senyenyane, ho na le karoloana feela ea HPMC. Phofo e tla qhibiliha hang-hang ha e kopana le metsi.
4. Joang ho ahlola boleng ba hydroxypropyl methylcellulose (HPMC) habonolo le ka mokhoa o hlakileng?
(1) Bosoeu: Le hoja bosoeu bo ke ke ba etsa qeto ea hore na HPMC e bonolo ho e sebelisa, 'me haeba ho eketsoa ho khanyang ka mokhoa oa tlhahiso, ho tla ama boleng ba eona.Leha ho le joalo, boholo ba lihlahisoa tse ntle li na le bosoeu bo botle.
(2) Bokhabane: Bokhabane ba HPMC ka kakaretso ke 80 mesh le 100 mesh, 120 mesh e nyane, botle bo botle, hangata bo betere.
(3) Phetiso: Kamora ho kenya HPMC ka metsing ho etsa colloid e bonaletsang, sheba phetiso ea eona.Ha phetisetso e kholoanyane, e betere, e bonts'a hore ho na le li-insoluble tse nyane ka hare.
(4) Tekanyo: ha tekanyo e kholoanyane, boima bo bongata bo betere.Bokhabane bo phahameng ka kakaretso bo bakoa ke litaba tse phahameng tsa hydroxypropyl tse ho eona, 'me ha hydroxypropyl e phahame, ho boloka metsi ho molemo.
5. Ke matšoao afe a mantlha a tekheniki a hydroxypropyl methyl cellulose (HPMC)?
Likahare tsa Hydroxypropyl le viscosity, tseo boholo ba tsona li amehileng ka matšoao ana a mabeli.Ho boloka metsi ho molemo ho batho ba nang le hydroxypropyl e ngata.High viscosity, ho boloka metsi, ho amana (ho e-na le ho feletseng) ho molemo, le viscosity e phahameng, e sebelisoang hamolemo ka seretse sa samente.
6. Lisebelisoa tsa mantlha tsa hydroxypropyl methyl cellulose (HPMC) ke life?
Lisebelisoa tse ka sehloohong tsa HPMC: k'hothone e hloekisitsoeng, methyl chloride, propylene oxide, joalo-joalo.
7. Mosebetsi o ka sehloohong oa tšebeliso ea hydroxypropyl methyl cellulose (HPMC) ka putty powder ke ofe?Ho na le karabelo ea lik'hemik'hale?
Ka phofo ea putty, HPMC e bapala likarolo tse tharo tsa ho tiisa, ho boloka metsi le ho haha.
Thickening: Cellulose e ka teteaneng ho emisa le ho boloka junifomo ea tharollo le holimo le tlase, le anti-sagging.
Ho boloka metsi: etsa hore phofo ea putty e ome butle, 'me u thuse k'halsiamo e bohlooho ho itšoara tlas'a ketso ea metsi.
Kaho: Cellulose e na le phello ea lubricating, e ka etsang hore putty powder e be le ts'ebetso e ntle ea ho sebetsa.
HPMC ha e kenye letsoho tšebetsong efe kapa efe ea lik'hemik'hale, e bapala karolo ea tšehetso feela.
8. Monko oa hydroxypropyl methyl cellulose (HPMC) ke ofe?
HPMC e hlahisoang ke mokhoa oa solvent e sebelisa toluene le isopropanol e le mokelikeli.Haeba e sa hlatsuoa hantle, e tla ba le monko o setseng.
9. Joang ho khetha hydroxypropyl methylcellulose (HPMC) e nepahetseng bakeng sa merero e fapaneng?
Tšebeliso ea phofo ea putty: tlhokahalo e tlase, viscosity ke 100,000, e lekane, ntho ea bohlokoa ke ho boloka metsi a le betere.
Tšebeliso ea seretse: litlhoko tse phahameng, viscosity e phahameng, 150,000 e molemo.
Kopo ea sekhomaretsi: lihlahisoa tsa hang-hang lia hlokahala, tse nang le viscosity e phahameng.
10. Tšebeliso ea hydroxypropyl methyl cellulose (HPMC) ka putty powder, ke eng e etsang hore putty powder e hlahise li-bubble?
Ka phofo ea putty, HPMC e bapala likarolo tse tharo tsa ho tiisa, ho boloka metsi le ho haha.Se ke oa kenya letsoho karabelong efe kapa efe.
Mabaka a li-bubble:
