MHEC ke eng?

Methyl Hydroxyethyl Cellulose (MHEC) ke motsoako oa cellulose ether o sebelisoang haholo liindastering tse kang kaho, meriana le lihlahisoa tsa tlhokomelo ea botho.E entsoe ka ho arabela selulose ka ethylene oxide le methyl chloride, e hlahisang motsoako o nang le lihlopha tse peli tsa hydroxyethyl le methyl tse khomaretsoeng mokokotlong oa cellulose.

MHEC e arolelana thepa e ngata le li-ether tse ling tsa cellulose joalo ka Hydroxypropyl Methylcellulose (HPMC) le Hydroxyethyl Methylcellulose (HEMC), ho kenyelletsa:

1. Ho Boloka Metsi: MHEC e na le bokhoni ba ho monya le ho boloka metsi, e leng se etsang hore e be molemo ho thepa ea kaho e kang seretse, li-grouts le li-adhesives tsa lithaele ho thibela ho omisoa pele ho nako le ho ntlafatsa ho sebetsa.
2. Thickening: E ​​ka eketsa viscosity ea metsoako ea mokelikeli, e leng molemo lits'ebetsong tse kang lipente, lirafshoa le lihlahisoa tsa tlhokomelo ea botho ho finyella botsitso bo lakatsehang.
3. Ho tsitsisa: MHEC e thusa ho tsitsisa li-emulsions le ho emisoa, ho thibela ho arohana ha mekhahlelo le ho boloka homogeneity ea lihlahisoa.
4. Tlhahiso ea Lifilimi: Ho tšoana le li-ethers tse ling tsa cellulose, MHEC e ka etsa filimi e tšesaane ha e sebelisoa holim'a libaka, e fana ka tšireletso le ho matlafatsa ho khomarela.
5. Thepa e Ntlafetseng ea Phallo: E ka ntlafatsa litšobotsi tsa phallo ea metsoako, ho nolofatsa ts'ebetso le ts'ebeliso.

Hangata MHEC e khethoa bakeng sa motsoako oa eona o khethehileng oa thepa, joalo ka bokhoni ba eona ba ho fana ka mokhoa o motle oa ho boloka metsi ha o ntse o boloka viscosity e tlaase ha e bapisoa le li-cellulose ethers tse ling.Sena se etsa hore e be e loketseng ka ho khetheha bakeng sa likopo moo ho hlokahalang ho boloka metsi a mangata ntle le ho eketsa ka mokhoa o feteletseng viscosity ea tlhahiso.

Methyl Hydroxyethyl Cellulose (MHEC) ke motsoako oa selulose oa ether o nang le mefuta e mengata e nang le mefuta e mengata ea likopo, moo thepa ea eona e le e teteaneng, e tsitsitseng, e bolokang metsi, le ea pele ea filimi e le ea bohlokoa haholo.
