Tsepamisa maikutlo ho Cellulose ethers

Litšebeliso tsa hydroxypropyl methylcellulose ke life?

Hydroxypropyl methylcellulose (HPMC) ke ether e seng ea ionic cellulose e nang le mesebetsi e mengata le mefuta e mengata ea lisebelisoa.

1. Lisebelisoa tsa mohaho

Lefapheng la kaho, HPMC e sebelisoa haholo lihlahisoa tse kang seretse sa samente, lisebelisoa tse thehiloeng ho gypsum, putty powder le sekhomaretsi sa lithaele. Mesebetsi ea eona ea mantlha e kenyelletsa:

Ho boloka metsi: HPMC e ka ntlafatsa haholo ho bolokoa ha metsi a seretse le ho thibela metsi ho tsoa mouoane ka potlako, ka ho etsa joalo ea ntlafatsa ts'ebetso ea kaho le phello ea ho folisa.

Ho tiisa le ho tlotsa: E ka eketsa viscosity le mokelikeli oa seretse, ho etsa hore mohaho o be bonolo le ho fokotsa ho apara ha lisebelisoa tsa kaho.

Anti-cracking: Ka ho ntlafatsa ho boloka metsi le ho khomarela seretse, HPMC e ka thibela seretse le samente hore li se ke tsa phunyeha nakong ea ho phekola.

2. Liaparo le lipente

Indastering ea ho penta le ho roala, HPMC e sebelisoa e le setenya, emulsifier le stabilizer. Mesebetsi ea eona e kenyelletsa:

Ho tiisa: Eketsa ponahalo ea pente, thibela ho sisinyeha, 'me u ntlafatse ho tšoana ha pente.

Botsitso: E thusa ho boloka ho hasana ho tšoanang ha li-pigment le li-fillers, ho thibela ho tsitsa le ho senya.

Thepa ea Anti-sag: Ntlafatsa ts'ebetso ea pente le ho thibela ho rotha le ho rotha.

3. Meriana le Lijo

Liindastering tsa meriana le lijo, HPMC e sebelisoa hangata matlapeng, li-capsules le li-additives tsa lijo. Mesebetsi ea eona ke e latelang:

Ho roala Letlapa: Joaloka lisebelisoa tsa ho roala letlapa, HPMC e ka laola ho lokolloa ha lithethefatsi le ho sireletsa lithethefatsi ho tloha mongobo le oksijene.

Khetla ea Capsule: HPMC ke motsoako o ka sehloohong oa li-capsules tsa meroho, tse loketseng batho ba jang meroho le batho ba hananang le li-capsules tse nkiloeng ke liphoofolo.

Li-thickeners le li-emulsifiers: Lijong, HPMC e sebelisoa e le ntho e teteaneng, emulsifier le stabilizer ho ntlafatsa sebopeho le tatso ea lijo.

4. Litlolo

Indastering ea litlolo, HPMC e sebelisoa lihlahisoa tse kang litlolo, litlolo, li-shampoo le litlolo tsa meno. Mesebetsi ea eona ea mantlha e kenyelletsa:

Thickening: E ​​fana ka viscosity e nepahetseng le botsitso, e etsa hore lihlahisoa li be bonolo ho li sebelisa le ho monya.

Lintho tsa ho etsa filimi: Theha filimi e sireletsang e bonaletsang ho matlafatsa matla a letlalo a mongobo.

Emulsification le botsitso: E thusa ho emulsify le ho tsitsisa metsoako ea oli ea metsi ho thibela stratification.

5. Lisebelisoa tse ling

HPMC e boetse e sebelisoa libakeng tse ling tse ngata tse kang:

Enke ea khatiso: E sebetsa e le setenya le se matlafatsang ho ntlafatsa boleng ba khatiso.

Temo: E sebelisoa e le setlamo sa ho koahela peo le chefo e bolaeang likokoanyana temong ho ntlafatsa katleho le sekhahla sa ho mela ha peo.

Textile: E sebelisoa mekhoeng ea khatiso ea masela le ho daea ho ntlafatsa boleng ba khatiso le ho potlaka ha mebala.

6. Likarolo le Melemo

HPMC e phetha karolo ea bohlokoa liindasteri tse sa tšoaneng ka lebaka la thepa ea eona e ikhethang ea 'mele le lik'hemik'hale. Likarolo tsa eona tsa mantlha li kenyelletsa:

Ho qhibiliha ha metsi: HPMC e ka qhibiliha ka potlako metsing a batang kapa a chesang ho etsa tharollo e hlakileng ea colloidal.

Biocompatibility le polokeho: HPMC ha e na chefo ebile ha e kotsi, e na le biocompatibility e ntle, 'me e sebelisoa haholo masimong a lijo le meriana.

Botsitso: E hanana le li-acids, alkalis le letsoai, e na le botsitso bo babatsehang 'me e ka boloka mosebetsi oa eona libakeng tse sa tšoaneng.

Hydroxypropyl methylcellulose e sebelisoa haholo kahong, ho roala, ho etsa meriana, lijo, litlolo le liindasteri tse ling ka lebaka la ho ikamahanya le maemo le ts'ebetso e ntle. Mesebetsi ea eona ea ho tiisa, ho boloka metsi, emulsification le botsitso e etsa hore e be motsoako oa bohlokoa lihlahisoa tse fapa-fapaneng, ho fana ka liphallelo tsa bohlokoa ho ntlafatsa ts'ebetso ea sehlahisoa le phihlelo ea mosebedisi.
