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, lirese 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 ho re, 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, ho sisinyeha, 'me mohaho oa ntlafatsoa.
6. HPMC ke ether e seng ea ionic cellulose, joale ke eng eo e seng ea ionic?
—— Karabo: Ho ea ka mantsoe a layman, li-non-ion ke lintho tse sa keneng metsing. Ionization e bolela mokhoa oo electrolyte e arohanang ka eona ho li-ion tse qosoang 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.
