HydroxypropypropyLese (HPMC)

Hydroxypropypropinyl MethylcelllOulose (HPMC), e tsejoang e le hypromellose, ke folymer ever e tsoang cellulose. Ho sebelisoa indastering e fapaneng bakeng sa thepa ea eona e ikhethang, ho kenyelletsa meralo, ea kaho, lijo le tlhokomelo ea motho. Tataisong ena e felletseng, re tla hlahloba sebopeho sa lik'hemik'hale, thepa, ts'ebetso ea ho etsa lintho, likopo le melemo ea HPMC ka botlalo.

1. Selelekela ho HPMC:

Hydroxypropypropypropinyl methylcelllulose (HPMC) ke selefounu e se nang ionic ether e tsoang cellulose ea tlhaho ka ho fetoloa ha tlhaho. E hlophisitsoe ke ho phekola Celsulose le Powerne Oxide le Methyl Chloride ho hlahisa Hydroxypropyl le lihlopha tsa Methyl. Polao e hlahisitsoeng e bonts'a mefuta e fapaneng ea thepa e e etsang e bohlokoa haholo likopo tse fapaneng tsa indasteri ea indasteri ea indasteri.

2. Sebopeho sa lik'hemik'hale le thepa:

HPMC e tšoauoa ka sebopeho sa eona sa lik'hemik'hale, tse nang le mokokotlo oa cellulose o nang le li-hydroxypropyl le methyl li-sup tsa li-hydroyl. Tekanyo ea sebaka (DS) ea hydropypropyl le lihlopha tsa methyl li ka fapana, tse hlahisang limaraka tse fapaneng tse kang lipehelo tse ikhethileng le li-turcolity le bo bong.

Thepa ea HPMC e susumetsoa ke lintho tse kang boima ba limok'hule, le bolelele ba sebaka sa hydroxypropypropy. Ka kakaretso, HPMC e bonts'a thepa e latelang ea bohlokoa:

• Mollo oa metsi
• Bokhoni ba ho etsa lifilimi
• Thepa ea thipa le geming
• Ketsahalo ea pele
• Botsitso holim'a boholo ba pH
• Ho tsamaisana le lisebelisoa tse ling

3. Ts'ebetso ea Tlhahiso:

Tlhahiso ea HPMC e kenyelletsa mehato e mengata, ho kenyelletsa:

1. Ho hlophisoa ha cellulose: choleulose ea tlhaho, hangata e sitisoa le k'hothone, e hloekisitsoe 'me e hloekisoe ho tlosa litšila le ligrin.
2. Karabelo ea Etherization: Colloulose e phekoloa ka Oxide le Methyl Chloride Chohloride ka lebaka la ho hlahisa li-hydroxypropyl le lihlopha tsa methyl.
3. Ho se nke lehlakore le ho phuthoa: sehlahisoa se hlahisoang se sa nke lehlakore ho tlosa Alkali e feteletseng ebe o hlatsoa ho tlosa lihlahisoa le litšila.
4. Ho omella le ho senyeha: HPMC e hloekisitsoeng e amme le fatše ka phofo e ntle e loketseng likopo tse fapaneng.

4. Mera le litlhaloso:

HPMC e fumaneha ka limaraka tsa limaraka tse fapaneng tsa limaraka tsa indasteri le lits'ebetso tse fapaneng. Tsena li kenyelletsa phapang ea Viscosty, boholo ba karoloana, mahlaseli a sebaka sa degree, le a botloholo. Lihlahisoa tse tloaelehileng tsa HPMC li kenyeletsa:

• Limaraka tse tloaelehileng tsa Viscosity (mohlala, 4000 CPS, 6000 CPS)
• Limaraka tse phahameng tsa Viscosity (mohlala, 15000 CPS, 20000 CPS)
• Limaraka tse tlase tsa Viscosity (mohlala, 1000 CPS, 2000 CPS)
• Limaraka tse khethehileng bakeng sa lits'ebeliso tse khethehileng (mohlala, ho lokolloa ka mokhoa o tsitsitseng, ho lokolloa ho laoloang)

5. Likopo tsa HPMC:

HPMC e fana ka ts'ebeliso ea liindastering tse fapaneng ka lebaka la thepa ea eona e fapana le ho lumellana le lisebelisoa tse fapaneng. Tse ling tsa likopo tsa bohlokoa tsa HPMC li kenyeletsa:

a. Indasteri ea meriana:

• Letlapa le Capsule Coatis
• Lihlooho tse laoloang
• Maqhubu le ho ripitla le litafole
• Litharollo tsa mahlo le li-suppenus
• LITLHAKISO TSA PUSO E joalo ka litlolo le litlolo

b. Indasteri ea kaho:

• Lihlahisoa tsa samente le tsa gypsum (mohlala, ho na le litlolo, likeleli)
• Meriana ea Tile le Grouts
• Lits'ebetso tsa Insulation le lits'ebetso tsa ho qeta (Eifs)
• Lits'oaetso tsa ho Iphahamisa
• Li-pente tse thehiloeng metsing le makhapetla a metsi

c. Indasteri ea lijo:

• Ho holisa le ho tiisa moemeli lihlahisoa tsa lijo
• Emulfier le ho emisoa ke moemeli oa lisaketsing le liaparo
• Tlatsetso ea Faber
• Gluten-Free Baking le confectionery

d. Tlhokomelo ea Botho le Litlolo:

• Thickener le moemeli oa ho emisa ka litlolo le lisele
• Tlama le Filimi ea Haipali Lihlahisoa tsa Tlhokomelo ea Moriri
• Ho lokolloa ha ho laoloe ho Foromo ea Skincare
• Li-drops tsa leihlo le li-dons tsa lense

6. Melemo ea ho sebelisa HPMC:

Ts'ebeliso ea HPMC e fana ka melemo e mengata litabeng tse fapaneng:

• Ts'ebetso e ntlafalitsoeng ea sehlahisoa le boleng
• Ho feto-fetoha ha ho feto-fetoha ha maemo le botsitso
• Bophelo bo Akarelwe Gelaf le ho fokotseha
• Ho sebetsa hantle ha ts'ebetso le katleho ea theko
• Ho latela litlhoko tsa taolo le litekanyetso tsa polokeho
• Tikoloho e botsoalle le biocometible

7. Litekanyetso le pono ea Bokamoso:

Tlhokahalo ea HPMC e lebelletsoe ho tsoela pele ho hola, e hlahisoa ke litopo tse ntseng li eketseha, nts'etsopele ea lits'ebeletso tsa phaello le ea tlhokomelo. Boiteko bo sa khaotseng le tsoelo-peleho ea kholo ea ntlafatso e ikemiselitse ho ntlafatsa liforomo tsa HPMC, ho holisa lits'ebetso tsa eona ho fihlela litlhoko tsa 'maraka oa ho tsamaisa' marakeng.

8. Qeto:

HydropxxypropyLe Methylcellll (HPMC) ke polymer e feto-fetohang e nang le lits'ebetso tse fapaneng tsa indastering e mengata. Mekhoa e ikhethang ea eona e ikhethang, joalo ka liallo tsa metsi, bokhoni ba lifilimi, bo etsa hore e rueng haholo meriana, kaho, lijo le litlolo. E le tsoelo-pele ea theknoloji le mebaraka ea 'maraka o batloang phetoho, HPmc e lebelletsoe ho bapala karolo ea bohlokoa ea indasteri e fapaneng.
