(Hydroxypropyl)methyl cellulose | CAS 9004-65-3

(Hydroxypropyl)methyl cellulose, e tsejoang hape ka khutsufatso ea eona ea HPMC kapa nomoro ea eona ea CAS 9004-65-3, ke cellulose ether e nkiloeng ho selulose ea tlhaho. Ke polymer ea semi-synthetic e sebelisoang haholo liindastering tse fapaneng ka lebaka la thepa ea eona e ikhethang le ho feto-fetoha ha maemo. Mona ke ho shebisisa kompone ena:

Sebopeho le Thepa:
1 Sebopeho: HPMC e entsoe ka phetoho ea lik'hemik'hale tsa selulose, moo lihlopha tsa methyl (-CH3) le hydroxypropyl (-CH2CHOHCH3) li hlahisoang mokokotlong oa cellulose.
2 Degree of Substitution (DS): Tekanyo ea ho nka sebaka e bolela palo e tloaelehileng ea lihlopha tse nkang sebaka ka yuniti ea tsoekere ka har'a ketane ea cellulose. E khetha thepa ea HPMC, joalo ka solubility, viscosity, le bokhoni ba ho etsa lifilimi.
3 Thepa: HPMC e bonts'a thepa e joalo ka botenya, ho boloka metsi, sebopeho sa filimi, le ts'ebetso ea bokaholimo. Thepa e ka fetoloa ka ho laola DS nakong ea ho kopanya.

Tlhahiso:
1. Cellulose Sourcing: Cellulose, thepa ea mantlha e tala bakeng sa HPMC, e nkuoa mehloling e ka nchafatsoang joalo ka makhasi a patsi kapa k'hothone.
Etherification: Cellulose e kena etherification, moo e sebetsanang le propylene oxide ho hlahisa lihlopha tsa hydroxypropyl ebe ka methyl chloride ho eketsa lihlopha tsa methyl.
2.Tlhakiso: Selulose e fetotsoeng e hloekisoa ho tlosa litšila le lihlahisoa, e leng se hlahisang sehlahisoa sa ho qetela sa HPMC.
Lisebelisoa:
3.Indasteri ea Kaho: HPMC e sebelisoa haholo linthong tsa kaho tse kang lirekere tse thehiloeng ho samente, li-plaster le li-adhesives tsa lithaele ho ntlafatsa ts'ebetso, ho boloka metsi, le ho khomarela.
4.Pharmaceuticals: E sebetsa e le binder, thickener, film former, and stabilizer in pharmaceutical formulations ho kenyeletsa matlapa, capsules, ophthalmic solutions, le topical creams.
5.Indasteri ea Lijo: HPMC e sebetsa e le setei, se tsitsisa, le emulsifier lihlahisoa tse fapa-fapaneng tsa lijo tse kang li-sauces, li-dressings, ice creams, le thepa e halikiloeng.
6.Litlolo le Tlhokomelo ea Botho: Ka litlolo le lihlahisoa tsa tlhokomelo ea botho, HPMC e sebelisoa e le ntho e teteaneng, e emisang, pele filimi, le moisturizer ka litlolo, lotions, shampoos le li-gel.
7.Paints and Coatings: E ntlafatsa ponahalo, ho hanyetsa ho sag, le thepa ea ho etsa filimi ea lipente tse entsoeng ka metsi, li-adhesives, le liphahlo.
Qetello:
(Hydroxypropyl) methyl cellulose, e nang le mefuta e fapaneng ea ts'ebeliso le thepa e ntle, ke motsoako oa bohlokoa lihlahisoa tse ngata tsa indasteri le tsa khoebo. Karolo ea eona ho ntlafatsa ts'ebetso, botsitso le ts'ebetso ea mefuta e fapaneng e etsa hore e be ea bohlokoa haholo mafapheng a mangata. Ha liindasteri li ntse li tsoela pele ho ntlafatsa, tlhoko ea HPMC e lebelletsoe ho tsoela pele, e tsamaisang tsoelo-pele e eketsehileng mekhoeng ea eona ea tlhahiso le lits'ebetso.
