Hydroxy ethyl methyl cellulose
Hydroxy ethyl methyl cellulose (HEMC), e tsejoang hape e le methyl hydroxy ethyl cellulose (MHEC), ke polymer e sebetsang ka mefuta e mengata e tsoang ho selulose. E entsoe ka phetoho ea lik'hemik'hale ea selulose, e hlahisang motsoako o nang le thepa e ikhethang e loketseng lits'ebetso tse fapaneng tsa indasteri. HEMC ke setho sa lelapa la cellulose ether 'me e arolelana lintho tse tšoanang le tse ling tse tsoang ho tse ling tse kang methyl cellulose (MC) le hydroxypropyl methyl cellulose (HPMC).
Lintho tsa Bohlokoa tsa Hydroxy ethyl Methyl Cellulose (HEMC):
1.Metsi a Solubility: HEMC e qhibiliha ka metsing, e etsa litharollo tse hlakileng le tse hlakileng. Thepa ena e lumella ho tšoara habonolo le ho kenngoa ka har'a mekhoa ea metsi, e etsang hore e tšoanelehe ho sebelisoa mefuteng e mengata ea libopeho.
2.Thickening Agent: HEMC e sebetsa e le setsi se sebetsang sa ho teteka ka mokhoa o sebetsang ka mokhoa o entsoeng ka metsi. Ha e qhibiliha ka metsing, liketane tsa polymer tsa HEMC lia kopanya 'me li theha mohaho oa marang-rang, ho eketsa viscosity ea tharollo. Thepa ena e bohlokoa bakeng sa ho laola rheology le thepa ea phallo ea lipente, likhomaretsi le lihlahisoa tse ling tsa metsi.
3.Bokhoni ba ho Etsa Lifilimi: HEMC e na le bokhoni ba ho etsa lifilimi ha e sebelisoa holim'a libaka ebe e lumelloa ho omella. Lifilimi tsena li pepeneneng, lia tenyetseha, 'me li bonts'a ho khomarela hantle ho li-substrates tse fapaneng. Lifilimi tsa HEMC li sebelisoa lits'ebetsong tse kang liphahlo, likhomaretsi le thepa ea kaho.
4.Tlhaloso e Ntlafetseng ea Metsi: HEMC e tsejoa ka thepa ea eona ea ho boloka metsi, e thusang ho thibela ho lahleheloa ke mongobo le ho boloka ho lumellana ho lakatsehang ha lihlahisoa ka nako. Thepa ena e bohlokoa haholo linthong tsa kaho tse joalo ka seretse, li-grouts le likhomaretsi tsa lithaele, moo ho hlokahalang hore ho sebetse nako e telele.
5.Tlhahiso e ntlafetseng ea ho sebetsa le ho khomarela: Ho eketsoa ha HEMC ho libopeho ho ka ntlafatsa ts'ebetso ka ho ntlafatsa ho phalla le ho ata ha thepa. E boetse e khothalletsa ho khomarela li-substrates, e lebisang ho tlamahano e ntle le ts'ebetso ea sehlahisoa sa ho qetela.
6.Ho tsitsisa ha Emulsions le Suspensions: HEMC e sebetsa e le stabilizer ka emulsions le suspensions, ho thibela ho arohana ha mekhahlelo le ho lokisa likaroloana. Thepa ena e thusa ho boloka homogeneity le botsitso ba metsoako, ho netefatsa boleng bo tsitsitseng ba sehlahisoa.
7.Ho lumellana le Lisebelisoa tse ling: HEMC e lumellana le mefuta e mengata ea lik'hemik'hale tse ling le li-additives, tse kenyelletsang li-pigment, li-fillers le li-rheology modifiers. E ka kenyelletsoa habonolo ka mekhoa e rarahaneng ho finyella litšobotsi tse lakatsehang tsa ts'ebetso.
Lisebelisoa tsa Hydroxy ethyl Methyl Cellulose (HEMC):
1.Lisebelisuoa tsa Kaho: HEMC e sebelisoa haholo indastering ea kaho e le setsi se teteaneng, se bolokang metsi, le se tlamang ka seretse se entsoeng ka samente, li-plaster le li-adhesives tsa lithaele. E ntlafatsa ts'ebetso, ho khomarela, le ho hanyetsa sag ea lisebelisoa tsena, e lebisang ho ts'ebetso e ntlafetseng le ho tšoarella.
2.Paints and Coatings: HEMC e hiriloe e le rheology modifier, thickener, le stabilizer ka lipente tse thehiloeng metsing, liphahlo le li-inks. E matlafatsa ho hasana ha pigment, e thibela ho fokotseha, 'me e ntlafatsa thepa ea tšebeliso ea metsoako ena.
3.Adhesives le Sealants: HEMC e sebelisoa ka li-adhesives le sealants ho ntlafatsa matla a ho kopanya, tack, le nako e bulehileng. E boetse e sebetsa e le sesebelisoa se teteaneng le rheology modifier, e fana ka viscosity e lakatsehang le thepa ea phallo bakeng sa ts'ebeliso.
4.Lihlahisoa tsa Tlhokomelo ea Botho: HEMC e fumana likopo ho lihlahisoa tsa tlhokomelo ea botho tse kang litlolo, litlolo, le li-shampoo e le ntho e teteaneng, e tsitsitseng, le ea pele ea filimi. E fana ka sebopeho se lakatsehang, botsitso, le thepa ea rheological ho libopeho tsena.
5.Meriana ea Meriana: Mekhahlelong ea meriana, HEMC e sebetsa e le setlamo se kopanyang, se senyang, le se laoloang-ho lokolloa ka matlapa, li-capsules le mafura. Biocompatibility ea eona le ho qhibiliha ha metsi ho etsa hore e tšoanelehe bakeng sa tšebeliso ea molomo le ea lihlooho.
6.Indasteri ea Lijo: Le hoja e sa tloaeleha hakaalo, HEMC e boetse e sebelisoa indastering ea lijo e le setepi, se tsitsitseng, le emulsifier lihlahisoa tse ling tse kang li-sauces, li-dressings le li-dessert.
Hydroxy ethyl Methyl Cellulose (HEMC) ke polima e feto-fetohang e nang le lits'ebetso tse fapaneng liindastering tse ngata. Ho qhibiliha ha eona ha metsi, thepa ea eona e teteaneng, bokhoni ba ho etsa filimi, le ho lumellana le lisebelisoa tse ling ho etsa hore e be ea bohlokoa kahong, lipente le liphahlo, li-adhesives, lihlahisoa tsa tlhokomelo ea botho, meriana, le lihlahisoa tsa lijo. Ha boiteko ba lipatlisiso le nts'etsopele bo ntse bo tsoela pele, HEMC e lebelletsoe ho bapala karolo ea bohlokoa haholoanyane lits'ebetsong tsa morao-rao tsa indasteri.
