Thepa ea Methyl Cellulose

Methyl cellulose (MC) ke cellulose ether e nang le lisebelisoa tse ngata tse fapaneng liindastering tse fapaneng, ho kenyeletsoa lijo, meriana le kaho. Tse ling tsa thepa ea MC li kenyelletsa:

1. Solubility: MC e qhibiliha ka metsing 'me e ka etsa tharollo e hlakileng le e tsitsitseng mocheso oa kamore. E boetse e qhibiliha ka har'a metsoako e meng ea tlhaho, joalo ka ethanol le methanol.
2. Viscosity: Viscosity ea litharollo tsa MC e ipapisitse le lintlha tse 'maloa, ho kenyeletsoa tekanyo ea ho nkela sebaka, boima ba limolek'hule, le ho tsepamisa mohopolo oa tharollo ea MC. Litharollo tsa MC li bonts'a boits'oaro ba phallo e seng ea Newtonian, ho bolelang hore viscosity e fetoha ka sekhahla sa ho kuta.
3. Ho etsa filimi: MC e ka etsa filimi ha e qhibiliha ka metsing ebe e omisoa. Filimi e entsoeng ke MC e tenyetseha, e pepenene, 'me e na le thepa e ntle ea thibelo.
4. Ho tsitsa ha mocheso: MC e na le botsitso bo botle ba mocheso 'me e khona ho mamella mocheso ho fihlela ho 200 ° C ntle le ho senyeha ho hoholo.
5. Tšebelisano: MC e lumellana le lisebelisoa tse ling tse ngata, ho kenyelletsa le li-cellulose ethers, starch, le liprotheine.
6. Hydrophilicity: MC e na le hydrophilic haholo, ho bolelang hore e na le kamano e matla ea metsi. Thepa ena e etsa hore MC e be le thuso ho lipeo moo ho boloka metsi ho leng bohlokoa, joalo ka lijong le lihlahisoa tsa tlhokomelo ea motho.

Ka kakaretso, thepa ea MC e etsa hore e be thepa e fapaneng e ka sebelisoang lits'ebetsong tse ngata tse fapaneng.
