Tlhahlobo e Felletseng ea Indasteri ea Tshebetso, Ts'ebetso, le Mekhoa ea Nakong e Tlang
'Marakeng oa thepa ea bareki o fetohang ka potlako kajeno,lihlahisoa tsa tlhokomelo ea lapeng—ho kenyeletsoa sesepa, lihlatsoi tsa bokaholimo, lino tse hlatsoang lijana, lihlatsoi tsa ntloana le li-spray tse sebetsang ka bongata—li tlameha ho fihlela litebello tse phahameng haholo. Bareki ba batla lihlahisoa tse seng feela tse sebetsang hantle ho hloekiseng empa hapee tsitsitseng, e bonolo ho e sebelisa, e khahlisa botle, 'me e ikarabella bakeng sa tikoloho. Ka mora litšobotsi tsena tsa tshebetso ho na le sehlopha sa di-additives tse sebetsang tse nolofalletsang katleho ya sehlahiswa ka lenyele. Har'a tsona,Hydroxypropyl Methyl Cellulose (HPMC)E hlahella e le motsoako o feto-fetohang haholo le oa bohlokoa.
Baqapi ba lik'hemik'hale ba lefats'e ba kang Dow Chemical Company, Ashland Global Holdings Inc., le Shin-Etsu Chemical Co., Ltd. ba kentse letsoho haholo ntlafatsong eaHPMCmahlale a etselitsoeng lits'ebetso tsa malapa le tsa indasteri. Sengoloa sena se hlahloba ka botebohore na ke hobane'ng ha HPMC e le ea bohlokoa haholo mefuteng ea tlhokomelo ea lapeng, ho sekaseka mekhoa ea eona, melemo, lits'ebetso le tebello ea bokamoso.
1. Ho utloisisa HPMC: Sebopeho le Motheo oa Ts'ebetso
Hydroxypropyl Methyl Cellulose (HPMC) ke setlolo se sireletsangether ea cellulose e sa qhibiliheng metsing, e seng ea ionice nkiloeng ho cellulose ea tlhaho. Ka phetoho ea lik'hemik'hale, lihlopha tsa hydroxyl tse ka har'a cellulose li nkeloa sebaka kelihlopha tsa methyl le hydroxypropyl, e leng se ntlafatsang ho qhibiliha ha metsi, boitšoaro ba mocheso, le thepa ea rheological.
Litšobotsi tsa Bohlokoa
- Non-ionic → e lumellana le boholo ba li-surfactants
- E qhibilihang ka metsing → e etsa ditharollo tse hlakileng kapa tse nang le mafome hanyane
- E arabela ka thermo → e bontša gelation ea mocheso
- Ho etsa filimi → ho etsa lera le sireletsang
- Ho teteana → ho laola ho teteana
Likarolo tsena li etsa hore HPMC e fetohe habonolo haholo ho pholletsa le mefuta e mengata ea mekhoa ea tlhokomelo ea lapeng.
2. Taolo ea Viscosity le Ntlafatso ea Rheology
2.1 Tshebetso e Nepahetseng ea ho Thibela
Karolo e 'ngoe ea bohlokoa ka ho fetisisa ea HPMC lihlahisoa tsa tlhokomelo ea lapeng ketaolo ea ho hlaka ha mahloBareki ba amahanya boleng ba sehlahisoa le sebopeho—sesepa haholo se ikutloa se sa sebetse, se teteaneng haholo se ikutloa se le thata ho se sebelisa.
HPMC e nolofalletsa:
- Ho teteana ho laoloang ho pholletsa le mekhoa e fapaneng
- Ho teteana ho tsitsitseng ha nako e ntse e ea
- Thepa ea phallo e ka fetoloang
Sena se netefatsa ts'ebetso e tsitsitseng ea sehlahisoa ho tloha tlhahisong ho isa tšebelisong ea sona ea ho qetela.
2.2 Boitšoaro ba ho Fokotsa ho Koahela
Lipontšo tsa HPMCthepa ea ho fokotsa ho kuta ha moriri e seng ea Newtonian, e bolelang:

- Ho fokotsoa ha litšila tsa sehlahisoa
6.2 Phihlelo e Boreleli ea Mosebelisi
Bareki ba khetha lihlahisoa tse latelang:
- Jala habonolo
- Ikutloe u boreleli
- Hlatsoa ka mokhoa o hloekileng
HPMC e kenya letsoho hophihlelo ea kutlo ea boleng bo holimo, ho ntlafatsa khotsofalo ea mosebelisi.
7. Ho lumellana le Li-Surfactants le Li-Additives
HPMC e tsamaisana hantle le:

- E ka bola
- Chefo e tlase
- E tšehetsa mekhoa e sireletsang tikoloho
Likhamphani tse kang Dow Chemical Company li tsetela lits'ebetsong tsa tlhahiso e tala.
10. Ho Bokgoni ba Ditjeo le ho Feto-fetoha ha Sebopeho
Leha HPMC e se sejo se theko e tlase, e fana ka:
- Bokgoni bo phahameng ka tekanyo e tlase
- Tshebetso e mengata
- Tlhoko e fokotsehileng ea li-additives tse ngata
Sena se lebisa hontlafatso ea litšenyehelo ka kakaretso.
11. Papiso le Li-Ether tse ling tsa Cellulose
Ha ho bapisoa le CMC leHEC:
- CMC→ theko e tlase, empa e sa tsitsa haholo lits'ebetsong tse ling
- HEC→ e ntle haholo bakeng sa metsi, maikutlo a betere a kutlo
- HPMC→ e molemohali bakeng sa li-gel, ho thehoa ha filimi le ho boloka metsi
12. Mekhoa ea Indasteri le Tebello ea Bokamoso
Bokamoso ba HPMC tlhokomelong ea lapeng bo kenyelletsa:
- Limaraka tse phahameng tsa ts'ebetso, tekanyo e tlase

- Litharollo tse mosa tikolohong le tse bolang
- Mekhoa e bohlale ea rheology
Likhamphani tse kang Ashland Global Holdings Inc. le Shin-Etsu Chemical Co., Ltd. li etella pele boqapi.
HPMC e fetohiletlatsetso ea bohlokoa lihlahisoa tsa tlhokomelo ea lapengka lebaka la bokhoni ba eona ba ho ntlafatsa ho hlaka, botsitso, ts'ebetso ea ts'ebeliso le boiphihlelo ba mosebelisi. Tlhaho ea eona ea mesebetsi e mengata e e lumella ho nkela metsoako e mengata sebaka ha e ntse e fana ka liphetho tse ntle.
Ha ditebello tsa bareki di ntse di eketseha mme botsitso bo ntse bo ba bohlokwa le ho feta, HPMC e tla bapala karolo e kgolo le ho feta ho bopeng bokamoso ba dihlahiswa tsa tlhokomelo ya lapeng.
