Methylhydroxyethylcellulose (MHEC) ke motsoako oa lik'hemik'hale o sebetsang ka tsela e fapaneng o fumanang lits'ebetso ho liindasteri tse fapaneng ka lebaka la thepa ea eona e ikhethang. MHEC ke ea lelapa la cellulose ethers, e tsoang ho cellulose ea tlhaho. E entsoe ka ho arabela alkali cellulose ka methyl chloride le ethylene oxide. Sehlahisoa se hlahisoang ke hydroxyethylated ho fumana methylhydroxyethylcellulose.
MHEC e khetholloa ke ho qhibiliha ha metsi, matla a ho teteaneng, thepa ea ho etsa lifilimi, le botsitso holim'a mefuta e mengata ea pH le mocheso. Litšobotsi tsena li etsa hore e tšoanelehe bakeng sa lits'ebetso tse fapaneng tse fapaneng, ho kenyelletsa kaho, meriana, lihlahisoa tsa tlhokomelo ea motho, lijo, le tse ling.
1. Indasteri ea Kaho:
Seretse le Lisebelisoa tsa Cementitious: MHEC e atisa ho sebelisoa e le moemeli oa ho thibela metsi le ho boloka metsi ka lihlahisoa tse entsoeng ka samente tse kang seretse, li-adhesives tsa lithaele, li-grouts le li-renders. E ntlafatsa ts'ebetso, ho khomarela, le nako e bulehileng, e lumellang hore ho be bonolo ho sebelisa le ho sebetsa hantle ha lisebelisoa tsena.
Lihlahisoa tsa Gypsum: Ka thepa e thehiloeng ho gypsum joalo ka metsoako e kopantsoeng le li-plaster, MHEC e sebetsa e le ntho e matlafatsang, e matlafatsang botsitso ba bona le ho hanyetsa ha bona.
2. Meriana:
Lihlahisoa tsa Tlhokomelo ea Molomo: MHEC e sebelisoa mefuteng ea sesepa sa meno e le sekontiri le se tlamang. E thusa ho boloka botsitso bo lakatsehang ba sesepa sa meno ha se ntse se tlatsetsa ho thepa ea sona ea sekhomaretsi.
Litharollo tsa Ophthalmic: Ka marotholi a mahlo le mafura, MHEC e sebetsa e le mofetoleli oa viscosity, e fana ka botenya bo hlokahalang bakeng sa boiketlo ba kopo le nako e telele ea ho kopana le sefahleho sa mahlo.
Litlhahiso tsa Lihlooho: MHEC e kenyelelitsoe ka har'a litlolo tse fapa-fapaneng, li-lotion, le li-gel e le moemeli o teteaneng le o tsitsitseng, ho ntlafatsa sebopeho le ho ata ha sehlahisoa.
3. Lihlahisoa tsa Tlhokomelo ea Motho:
Li-Shampoos le Li-conditioners: MHEC e ntlafatsa ponahalo ea lihlahisoa tsa tlhokomelo ea moriri, e fana ka mokhoa o boreleli le o monate o ntlafatsang ho ata le ho netefatsa hore esita le ho ajoa ha metsoako e sebetsang.
Lisebelisoa tsa Letlalo: Lihloekisong tsa sefahleho le ho hlatsoa 'mele, MHEC e sebetsa e le motenya o bonolo le o tsitsitseng, e leng se tlatsetsang sebopeho sa sehlahisoa le thepa ea ho phophoma.
Litlolo: MHEC e sebelisoa litlolong tse kang litlolo, litlolo, le lihlahisoa tsa litlolo ho lokisa viscosity, ho ntlafatsa sebopeho, le ho tsitsisa li-emulsions.
4. Indasteri ea Lijo:
Li-additives tsa Lijo: MHEC e hiriloe e le setei, se tsitsitseng le se emulsifier lihlahisoa tse fapa-fapaneng tsa lijo, ho akarelletsa le li-sauces, liaparo, lihlahisoa tsa lebese le li-dessert. E thusa ho boloka sebopeho se lakatsehang, ho thibela syneresis, le ho matlafatsa molomo.
Ho Baka ha Gluten: Ka ho baka ha gluten, MHEC e ka sebelisoa ho etsisa litšobotsi tsa viscoelastic tsa gluten, ho ntlafatsa ho tsitsisa ha hlama le ho hlahisa lihlahisoa tse kang bohobe, likuku le likuku.
5. Lipente le Mekhabiso:
Latex Paints: MHEC e eketsoa ho lipente tsa latex le liphahlo e le motenya le mofetoleli oa rheology. E ntlafatsa brushability, tshebediso ya rolara, le tshebetso e akaretsang ya filimi ya pente ka ho thibela ho sagging le marotholi.
Liaparo tsa Kaho: Lirapeng tsa marako, siling, le li-facade, MHEC e ntlafatsa ponahalo le ho sebetsa ha sebopeho, ho netefatsa hore ho koaheloa ka mokhoa o ts'oanang le ho khomarela.
6. Likhomaretsi le Li-Sealants:
Li-Adhesives tse thehiloeng ho Metsi: MHEC e sebetsa e le setsi se teteaneng ho li-adhesives le li-sealants tse thehiloeng metsing, ho ntlafatsa tackiness, matla a tlamo le thepa ea kopo.
Li-Grouts tsa Tile: Ka li-tile grout formulations, MHEC e sebetsa e le rheology modifier, e ntlafatsa thepa ea phallo le ho thibela ho fokotseha le ho phunyeha ha ho phekoloa.
7. Lisebelisoa tse ling:
Mekelikeli ea ho Cheka Oli: MHEC e sebelisoa ka har'a maro a ho cheka liliba tsa oli e le sesebelisoa sa viscosifier le se laolang tahlehelo ea mokelikeli, se thusang ho boloka botsitso ba sekoti le ho thibela ho falla ha mokelikeli.
Khatiso ea Textile: Likhatisong tsa khatiso ea masela, MHEC e sebelisoa e le sekontiri le se tlamang, se nolofatsang ts'ebeliso ea lidae le li-pigments holim'a masela.
Methylhydroxyethylcellulose (MHEC) ke ether ea cellulose e feto-fetohang e nang le mefuta e mengata ea lisebelisoa ho pholletsa le liindasteri tse fapaneng. Bokhoni ba eona ba ho teteana, ho tsitsisa le ho fetola thepa ea rheological ea metsoako e etsa hore e be ea bohlokoa haholo ho tsa kaho, meriana, lihlahisoa tsa tlhokomelo ea motho, lijo, lipente, likhomaretsi le tse ling. Ha liindasteri li ntse li tsoela pele ho ntlafatsa le ho hlahisa lihlahisoa tse ncha, MHEC e ka 'na ea lula e le motsoako oa bohlokoa mefuteng e mengata, e tlatsetsang ts'ebetsong ea bona, ts'ebetsong, le boipiletso ba bareki.
