Tlhahlobo ea ho ts'oaroa ha metsi ea Hydroxypropypropyl Methylcelllllulose (HPMC)

1. Selelekela

Hydroxypropypropinyl methylcelllulose Ho boloka metsi a matle ka metsi ke e 'ngoe ea litšobotsi tsa bohlokoa tsa kopo e pharalletseng ea HPMC.

2. Sebopeho le thepa ea hpmc

2.1 Sebopeho sa lik'hemik'hale
HPMC ke semi-synthelose celthelose ether. Sebaka sa hydroxypropyl le methyl selelekela ka sebopeho sa lik'hemik'hale se fana ka linyeoe tse ikhethang tsa lianye le tsa colloidal. Sebopeho sa mantlha sa HPMC e na le liketane tsa Β-D-Glucose tsa Cellulose, moo litloholo tse ling tsa hydroyyl li nkeloang ke lihlopha tsa methyl le hydroxyl. Boemo le tekanyo ea sebaka sena sa lintho tsena li ama linyebelle ka kotloloho li ama linyebelle, tse bolokiloeng ka metsi le metsi a HPMC.

2.2 Thepa ea 'mele ea' mele
Sello sa metsi: HPMC e qhibiliha habonolo ka metsing a batang 'me a etsa tharollo ea colloidal ka metsing a chesang.
Thepa ea thickening: e ka theha tharollo ea li-viscous ka metsing mme e na le phello e ntle e toba.
Thepa e 'ngoe e etsang lifilimi: E ka theha filimi e pepenoang le e boreleli.
Ho emisoa: E na le ts'ebetso e ntle ea ho emisoa ka tharollo mme e ka tsitsisa taba.

3. Ho boloka metsi ka hpmc

3.1 Mechanism ea ho boloka metsi
Ho boloka metsi ka HPMC ho hlahisoa haholo ka tšebelisano lipakeng tsa hydroxyl le lihlopha tsa sebaka ka sebopeho sa likelek'hule le limolek'hule tsa metsi. Ka ho khetheha, HPMC e boloka metsi ka menyako e latelang:
Hydrogen Hoba: Lihlopha tsa hydroyl tse ka limolek'hule tsa HPMC li hlasimollang likutu tsa metsi le limolek'hule tsa metsi. Matla ana a thusa limolek'hule tsa metsi hore li tlameletsoe ka thata ho potoloha HPMC, li fokotsa mouoane oa metsi.
Phello e phahameng ea liketsahalo: Tharollo e phahameng ea pono e phahameng e thehiloeng ke HPMC ka metsing e ka thibela ho sisinyeha ha metsi, ka hona a fokotsa tahlehelo ea metsi.
Sebopeho sa marang-rang: Sebopeho sa marang-rang se thehiloeng ke HPMC ka metsing li ka hapa le ho boloka limolek'hule tsa metsi, e le hore metsi a ka ajoa ka mokhoa o tšoanang ka sebopeho sa marang-rang.
Phello ea Colloid: Mokopi o thehiloeng ke HPMC e ka koahela metsi ka har'a kokoana-hloko 'me e eketsa nako ea ho boloka metsi.

Lintlha tsa 3.2 tse amang ho boloka metsi
Degree of Study: ho boloka metsi ha hpmc ho angoa ke boemo ba sebaka (DS). Ho phahamisoa ha sebaka, ho matla le ho feta ha hydrophphilicity ea HPMC le ts'ebetso ea eona ea metsi a ho boloka metsi.
Boima ba Molecular: Boima bo phahameng ba balek'hente bo thusa ho theha marang-rang a balek'hule manonyeletso a kelello, ka ho etsa joalo a tlisa bolokolohi ba metsing.
Ho tsepamisa mohopolo: Khatello ea tharollo ea HPMC e na le phello e bohlokoa ho boloka metsi. Litharollo tse phahameng tsa mahloriso li khona ho theha litharollo tse ngata tse chefo le meaho e tsitsitseng ea marang-rang, ka tsela eo ka hona e boloka metsi a mangata.
Mocheso: ho boloka metsi ka hpmc ho fapana ka mocheso. Ha mocheso o tsoha, ke pono ea tharollo ea HPMC e fokotseha, e fella ka ho fokotseha ha metsi.

4. Sepehelo sa HPMC maemong a fapaneng

4.1 Lisebelisoa tsa Kaho
Lisebelisoa tsa moaho, HPMC e sebelisoa e le ho khutlisetsoa ka metsing bakeng sa lihlahisoa tsa samente le tsa gyppum. Mesebetsi ea eona e ka sehloohong e kenyelletsa:
Ntlafatso ea ho haha: Ka ho boloka mongobo o lekaneng, nako e bulehileng ea samente le saypsum e atoloha, e etsa hore ts'ebetso ea kaho e sisinyehe.
Fokotsa mapetso a likotlo: Ho boloka metsi hantle a metsi ho thusa ho fokotsa mapera nakong ea ho omisa le ho ntlafatsa matla le ho se khone ho ba le matla.
Ntlafatsa matla a bonnte: Ho lidhereives tsa dile, HPMC li ka eketsa matla a ho band le ho ntlafatsa matla a ho tlala.

4.2 Litokisetso tsa meriana
Meputso ea meriana, ho boloka metsi ho HPMC ho bapala karolo ea bohlokoa ho tokollo le botsitso ba lithethefatsi:
Litokisetso tsa ho lokolla: HPMC li ka sebelisoa e le mokhoa o tsitsitseng bakeng sa lithethefatsi ho fihlela lithethefatsi tse sireletsehileng tsa ho kenella ha metsi le sekhahla sa disceotion sa lithethefatsi.
Bosholu le banyane: Lithethefatsi tse nontseng

LITLHAKISO TSA BOPHELO
Indastering ea Lijo, HPMC e sebetsa e le bolo ea thickener le seterata sa eona sa metsi se sebelisetsoa ho:
Ho ntlafatsa tatso: Ka ho boloka metsi, HPMC e ka ntlafatsa sebopeho le tatso ea lijo, e etsa hore e be monate le ho e thabisa.
Ho atoloha bophelo ba sehatse: Ka ho boloka metsi, HPMC e ka thibela ho lahleheloa ke metsi nakong ea polokelo, ka tsela e ka fetisang bophelo ba sehatsetsing.

Li-cosmetics tsa 4.4
Li-cosmetics, ho boloka metsi ka hpmc ho sebelisetsoa:
Tšusumetso e Mofokoi: Ha Moisturizer, HPMC e ka thusa ho koala mongobo sebakeng sa lehlaka 'me u fane ka phello ea nako e telele ea nako e telele.
Ho tsitsisa ha ho tsitsipana: ho emulsions le ho emisa - HPMC e tiisa sehlahisoa le ho thibela ho stratation le thetsi.

Ho boloka metsi ka metsi ho hlatsoa hpmc ho e etsa ntho ea bohlokoa masimong a mangata. E boloka metsi mme e fokotsa mouoane oa metsi ka ho tlatlapa metsi ka ho tlatlapa ea metsi, litlamorao tse phahameng tsa pono, sebopeho sa marang-rang le litlamorao tsa marang-rang. Ho boloka metsi ho angoa ke boemo ba sebaka, boima ba semolao le mocheso, tse khethollang ts'ebetso ea HPMC ka ts'ebeliso e itseng. Hore na thepa ea moaho, litokisetso tsa meriana, limpho tsa meriana, litlolo tsa lijo kapa litlolo tsa metsi, ho boloka metsi ho ntlafatsa boleng ba sehlahisoa le tšebetso ea sehlahisoa.
