Methylcellulose ke derivative e tloaelehileng ea selulose e sebelisoang haholo meriana, lijo le indasteri. Ke polymer e qhibilihang ka metsing haholo-holo e entsoeng ka selulose ea limela tsa tlhaho ka phetoho ea lik'hemik'hale, 'me e na le lintho tse ngata tse ikhethang, tse kang ho teteaneng, ho tsuba, ho emisa, ho etsa filimi le ho boloka metsi.
Litšobotsi le tšebeliso ea methylcellulose
Thickener le gelling agent: Lefapheng la lijo, methylcellulose e atisa ho sebelisoa e le ntho e teteaneng le ea gelling ho thusa ho ntlafatsa sebopeho le tatso ea sehlahisoa. Ka mohlala, lihlahisoa tse kang ice cream, jeme le liaparo tsa salate, methylcellulose e ka fana ka viscosity e ntle le ho ntlafatsa botsitso ba sehlahisoa.
Bajari ba lithethefatsi le li-excipients: Ka indasteri ea meriana, methylcellulose e atisa ho sebelisoa e le motsoako oa lithethefatsi, joalo ka se tlamang le ho tlatsa matlapa. E ka boela ea sebelisoa e le moemeli oa ho lokolloa ha lithethefatsi ho laola sekhahla sa ho lokolloa ha lithethefatsi le ho netefatsa botsitso le ho tšoarella ha phello ea lithethefatsi.
Kopo ho thepa ea mohaho: Lefapheng la thepa ea mohaho, methylcellulose e sebelisoa e le setsi se teteaneng le se bolokang metsi ka samente, gypsum le liphahlo ho ntlafatsa ts'ebetso ea kaho le ho tšoarella ha thepa.
Phapang lipakeng tsa methylcellulose le li-antifoaming agents
Li-antifoaming agents ke sehlopha sa lik'hemik'hale tse sebelisetsoang ho hatella kapa ho felisa li-bubble ka har'a maro, 'me hangata li fumanoa ho lokisa lijo, meriana, litlolo, ho etsa pampiri, lik'hemik'hale le ho hloekisa metsi. Hangata li-antifoaming agents li sebetsa ka ho fokotsa tsitsipano ea holim'a metsi ho thibela ho thehoa ha foam, kapa ka ho khothalletsa ho oa ka potlako ha foam e entsoeng. Li-antifoaming agents tse tloaelehileng li kenyelletsa oli ea silicone, li-polyethers, li-ester tse mafura a mafura, le likaroloana tse itseng tse tiileng, tse kang silicon dioxide.
Leha ho le joalo, methylcellulose ha se moemeli oa antifoaming ka tlhaho. Le hoja methylcellulose e ka etsa tharollo ea viscous ha e qhibiliha ka metsing, 'me viscosity ea tharollo ena e ka' na ea ama ho thehoa ha foam maemong a mang, ha e na lisebelisoa tse sebetsang ka holimo tsa mahlahana a tloaelehileng a antifoaming. Ka mantsoe a mang, mosebetsi o ka sehloohong oa methylcellulose ke hore e sebetsa e le motenya, moemeli oa gelling, moemeli oa ho emisa, joalo-joalo, ho e-na le ho sebelisoa ka ho khetheha ho hatella kapa ho felisa foam.
Pherekano e ka bang teng le linyeoe tse khethehileng
Le hoja methylcellulose e se moemeli oa antifoaming, ka mekhoa e itseng kapa lihlahisoa tse itseng, e ka 'na ea ama ka tsela e sa tobang boitšoaro ba foam ka lebaka la phello ea eona e teteaneng le litšobotsi tsa tharollo. Ka mohlala, lijong tse ling kapa lihlahisoa tsa lithethefatsi, li-viscosity tse phahameng tsa methylcellulose li ka fokotsa ho thehoa ha li-bubble kapa tsa etsa hore li-bubble tse entsoeng li qhalane ka potlako. Leha ho le joalo, phello ena ha e lumelle hore e khethoe e le moemeli oa antifoaming hobane mokhoa oa eona o ka sehloohong oa ts'ebetso o fapane haholo le tlhaho ea lik'hemik'hale le mokhoa oa ts'ebetso ea li-antifoaming agents.
Methylcellulose ke motsoako o sebelisoang haholo oa selulose o nang le mesebetsi e mengata, empa ha o nkoe e le moemeli oa antifoaming. Le hoja e ka 'na ea e-ba le phello boitšoarong ba ho phophoma maeba maemong a itseng, sena ha se bolele tšebeliso ea eona ea mantlha kapa mokhoa oa ts'ebetso. Li-antifoaming agents hangata li na le ts'ebetso e khethehileng ea holim'a metsi le matla a ho laola foam, athe methylcellulose e sebelisoa haholo bakeng sa ho teteka, ho phunya, ho emisa le ho boloka metsi. Ka hona, ha u sebelisa methylcellulose, haeba ho hlokahala hore ho be le phello e hlakileng ea antifoaming, moemeli o khethehileng oa antifoaming o lokela ho khethoa hore o sebelisoe hammoho.
