Hydroxypropyl methylcellulose e na le tumellano e ntle

Hydroxypropyl methylcellulose e entsoe ka selulose ea k'hothone e hloekileng haholo ka etherification e khethehileng tlas'a maemo a alkaline, 'me ts'ebetso eohle e phethoa tlas'a tlhokomelo e itekanetseng. Ha e qhibilihe ka har'a ether, acetone le absolute ethanol, 'me e kokomoha hore e be motsoako o hlakileng kapa oa maru hanyenyane metsing a batang. Tharollo ea metsi e na le mosebetsi oa holim'a metsi, pepeneneng e phahameng le ts'ebetso e tsitsitseng. E ka sebelisoa e le lithaele tsa peista, 'mabole, mokhabiso oa polasetiki, matlafatso ea peista, hape e ka fokotsa bongata ba samente. Ts'ebetso ea ho boloka metsi ea hydroxypropyl methyl fiber e thibela slurry ho phatloha ka lebaka la ho omisa ka potlako ka mor'a kopo, 'me e matlafatsa matla ka mor'a ho thatafala.

Ka ho fokotseha ha litaba tsa methoxyl, ntlha ea gel ea eketseha, ho qhibiliha ha metsi hoa fokotseha, 'me mosebetsi oa bokaholimo le oona oa fokotseha. Sehlahisoa se boetse se na le litšoaneleho tsa bokhoni ba ho teteka, ho hanyetsa letsoai, phofo e tlaase ea molora, botsitso ba pH, ho boloka metsi, botsitso ba dimensional, ho etsa filimi e babatsehang, le mefuta e mengata ea ho hanyetsa li-enzyme, ho arohana le ho kopana.

E sebelisoa e le motenya, dispersant le stabilizer indastering ea pente, 'me e na le ts'ebelisano e ntle ea metsi kapa lihlahisoa tsa tlhaho. E le ho tlosa pente. E sebelisoa e le motenya, dispersant le stabilizer indastering ea enke, 'me e na le tšebelisano e ntle metsing kapa lihlapolli tsa tlhaho. Sehlahisoa sena se boetse se sebelisoa haholo ho letlalo, lihlahisoa tsa pampiri, ho boloka litholoana le meroho le indastering ea masela.
