Hec ke sekhobo se hlahisoang ke ho kenyelletsa Ethyl (-ch2chchchHoh) ka kemiso ea lilolule tsa cellule some. Sebopeho sa hydroxethyl le 'mala o mong oa hydroxyl, -oh) oa cellulose o nkeloa sebaka ke lihlopha tsa Ethyl hydroxyl (-ch2chchOhhh. Ho fapana le hpmc, sebopeho sa limolek'hule sa hec se na le hydroxethyl e le 'ngoe feela ea hydroeth ebile ha e na lihlopha tsa methyl.
2. Allubity ea Metsi
Ka lebaka la phapang ea sebopeho, scoudity ea metsi ea HPMC le hec e fapane.
HPMC: HPMC e na le liallo tse ntle tsa metsi, haholo-holo ka boleng ba PH ea mahala kapa e nyane ea Alkaline Kenyelletso ea lihlopha tsa hae tsa methyl le hydropity e ka eketsa pono ea eona ka ho sebelisana le limolek'hule tsa metsi.
Hec: Hangata o qhibiliha metsing, empa allourity ea eona e futsanehile, 'me hangata e hloka litlamorao tse matla tsa ho futhumatsa. SHOGUBIN ea eona e amana le phapang ea sebopeho sa cellulose le hydrophphilicity ea sehlopha sa hydroyethl.
3. Litaba tsa liketsahalo tsa Viscosity le tsa Rheology
HPMC: Ka lebaka la boteng ba lihlopha tse peli tse fapaneng tsa hydrophphilic (methyl le hydroxypropity) ho HPM Maemong a fapaneng, HPMC e ka fana ka phetoho ho tsoa ho pono e tlase ea pono e phahameng, 'me Viscosity e tsotella haholo liphetoho.
Hec: Ke pono ea hec e ka fetoloang ka ho fetola khatello, empa phetoho ea phetoho ea eona ea tlhahlobo ea lipapente e nyane ho feta ea HPMC. Hec o sebelisoa haholo maemong ao ho sa tsotelleng pono e mahareng hoa hlokahala, haholo-holo ho haheng. Melemo ea liphiri tsa Hec e tsitsitse, haholo maemong acidic kapa a sa nke lehlakore, hec a ka fana ka lipono tse tsitsitseng.
4. Masimo a kopo

Indasteri ea kaho: HPMC e sebelisoa hangata khoebong ea kaho ho ntlafatsa phatla, ho sebetsa le ho thibela mapetso.
Indasteri ea pharmacectication: Ha e le moeti oa taolo ea lithethefatsi, HPMC e sebelisoa haholo indastering ea meriana. E ke ke ea sebelisoa feela e le moemeli ea etsang litafole tsa matlapa le lilulu, empa hape le ho khomarela lithethefatsi ka botlalo.
Indasteri ea lijo: hpmc hangata e sebelisoa ka ts'ebetso ea lijo e le seliba, thickener kapa emulfier ho ntlafatsa sebopeho le tatso ea lijo.
Indasteri ea Li-Cosmetics: Joalokaha thickener, HPMC e sebelisoa haholo litsing tse kang litlolo, le baetsi ba lihlahisoa.
Hydroxeeyl celloulose (Hec)
Indasteri ea kaho: Hec o sebelisoa hangata saholiie, gypsum, le litlhahiso tsa lihlapiso tsa ho ntlafatsa phokotsi le nako ea ho boloka sehlahisoa.
Bahlahisi: Hangata o sebelisoa hangata ka har'a litlolo tsa malapa, lijana tse ling tse hlahelletseng le lihlahisoa tse ling ho eketsa pono ea sehlahisoa le ho ntlafatsa ts'ebetso ea ho hloekisa.
Indasteri ea Li-Cosmetics: Hec e sebelisoa haholo lihlahisoa tsa tlhokomelo ea letlalo, shampoos, joalo-joalo e le moemeli oa thickener le ho emisoa ha sehlahisoa.
Nts'etsopele ea oli: HEC e ka sebelisoa ts'ebetsong ea oli ho tsoaloe e le thipa ea metsi a senyehileng metsing ho thusa ho eketsa pono ea metsi le ho ntlafatsa phello e chesang.
5. Ph Clitity
HPMC: HPMC e tsotella haholo ho theha liphetoho. Tlas'a maemo acidic, qubu ea HPMC e fokotsehile, e ka ama tšebetso ea eona. Ka hona, hangata e sebelisoa ka pateral ho ea tlaase ho li-alkaline.
Hec: hec e lula e tsitsitse ho tsoa ho blos e pharaletseng. E na le teko e matla ea tikoloho ea acidic le ea alkaline, kahoo hangata e sebelisoa ka mekhoa e hlokang ho tsitsa e matla.
HpmcMmeHecE fapana ka sebopeho sa limolek'hule, sokoli, liphetoho tsa tlhahlobo ea liketsahalo le libaka tsa kopo. HPMC e na le ts'ebetso e ntle ea metsi le liketsahalo tsa tlhahlobo, 'me e loketse likopo tse hlokang lipapatso tse phahameng tsa pono kapa ts'ebetso e sa laoloeng; Ha hec o na le botsitso ba phetho e ntle le lits'ebetso tse fapaneng tsa lits'ebetso, 'me e loketse liketsahalo tse hlokang tloaelo ea mahaeng le e tlase ea pono. Lipholisong tsa bona, khetho ea eona boitsebiso bo hlokang ho hlahlojoa ho latela litlhoko tse itseng.
