1. Lebitso la lebitso la hydroxypropyl methylcellulose ke lefe?
—— Karabo: Hydroxypropyl Methyl Cellulose, English: Hydroxypropyl Methyl Cellulose Khutsufatso: HPMC kapa MHPC Alias: Hypromellose;Cellulose Hydroxypropyl Methyl Ether;Hypromellose, Cellulose, 2-hydroxypropylmethyl Cellulose ether.Cellulose hydroxypropyl methyl ether Hyprolose.
2. Tšebeliso e ka sehloohong ea hydroxypropyl methylcellulose (HPMC) ke efe?
—— Karabo: HPMC e sebelisoa haholo linthong tsa kaho, lijalo, lirekere tsa maiketsetso, lirafshoa, meriana, lijo, masela, temo, litlolo, koae le liindasteri tse ling.HPMC e ka aroloa ka sehlopha sa kaho, sehlopha sa lijo le sehlopha sa meriana ho latela sepheo.Hajoale, boholo ba lihlahisoa tsa lapeng 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.
3. Ho na le mefuta e mengata ea hydroxypropyl methylcellulose (HPMC), 'me ke phapang efe ea tšebeliso ea eona?
—— Karabo: HPMC e ka aroloa ka mofuta oa hang-hang le mofuta oa ho qhibiliha o chesang.Lihlahisoa tsa mofuta oa hang-hang li hasana ka potlako metsing a batang ebe li nyamela ka metsing.Ka nako ena, mokelikeli ha o na viscosity hobane HPMC e qhalakanngoa feela metsing ntle le ho qhibiliha ha sebele.Hoo e ka bang metsotso e 2, viscosity ea mokelikeli e ntse e eketseha butle-butle, e etsa "viscous colloid" e hlakileng.Lihlahisoa tse chesang, ha li kopane le metsi a batang, li ka qhalana ka potlako metsing a chesang 'me tsa nyamela metsing a chesang.Ha mocheso o theohela ho mocheso o itseng, viscosity e tla hlaha butle-butle ho fihlela e etsa "viscous colloid" e hlakileng.Mofuta oa hot-melt o ka sebelisoa feela ka phofo ea putty le seretse.Ka sekhomaretsi sa metsi le pente, ho tla ba le ts'ebetso ea lihlopha 'me e ke ke ea sebelisoa.Mofuta oa hang-hang o na le mefuta e mengata e fapaneng ea lits'ebetso.E ka sebelisoa ka phofo ea putty le seretse, hammoho le sekhomaretsi sa metsi le pente, ntle le li-contraindications.
4. Mokhoa oa ho khetha hydroxypropyl methylcellulose (HPMC) e loketseng merero e fapaneng joang?
—— Karabo :: Kopo ea phofo ea putty: Litlhoko li batla li le tlaase, 'me viscosity ke 100,000, e lekaneng.Ntho ea bohlokoa ke ho boloka metsi hantle.Tšebeliso ea seretse: litlhoko tse phahameng, viscosity e phahameng, 150,000 e molemo.Tšebeliso ea sekhomaretsi: lihlahisoa tsa hang-hang tse nang le viscosity e phahameng lia hlokahala.
5. Ke eng e lokelang ho lebisoa tlhokomelo ho ts'ebetsong ea sebele ea kamano pakeng tsa viscosity le mocheso oa HPMC?
—— Karabo: The viscosity ea HPMC e fapane ka tsela e fapaneng le mocheso, ke hore, viscosity ea eketseha ha mocheso o fokotseha.Viscosity ea sehlahisoa seo hangata re buang ka sona se bolela sephetho sa tlhahlobo ea tharollo ea metsi a 2% mochesong oa likhato tse 20 tsa Celsius.
Litšebelisong tse sebetsang, hoa lokela ho hlokomeloa hore libakeng tse nang le phapang e kholo ea mocheso pakeng tsa lehlabula le mariha, ho kgothaletswa ho sebelisa viscosity e batlang e le tlaase nakong ea mariha, e leng se loketseng ho haha.Ho seng joalo, ha mocheso o le tlase, viscosity ea cellulose e tla eketseha, 'me letsoho le tla ba boima ha le senya.
Viscosity e bohareng: 75000-100000 haholo-holo e sebelisetsoang putty
Lebaka: ho boloka metsi hantle
Viscosity e phahameng: 150000-200000 Haholo-holo e sebelisetsoang polystyrene particle thermal insulation mortar rabara phofo le vitrified microbead thermal insulation seretse.
Lebaka: The viscosity e phahame, seretse ha se bonolo ho oa, sag, 'me mohaho oa ntlafatsoa.
6. HPMC ke ether e seng ea ionic cellulose, joale ke eng eo e seng ea ionic?
—— Karabo: Ka mantsoe a layman, li-non-ion ke lintho tse sa ioniseng metsing.Ionization e bolela mokhoa oo electrolyte e arohanang ka eona ho li-ion tse lefshoang tse ka tsamaeang ka bolokolohi ka har'a motsoako o itseng (joaloka metsi, joala).Ka mohlala, sodium chloride (NaCl), letsoai leo re le jang letsatsi le leng le le leng, le qhibiliha ka metsing 'me le ionize ho hlahisa li-ion tsa sodium (Na+) tse tsamaisoang ka bolokolohi le li-ion tsa chloride (Cl) tse qosoang hampe.Ke ho re, ha HPMC e kenngoa ka metsing, e ke ke ea ikarola ho li-ion tse qosoang, empa e teng ka mokhoa oa limolek'hule.
