Ntho e 'ngoe le e' ngoe eo U Lokelang ho e Tseba ka Methyl Hydroxyethyl Cellulose (MHEC)

Methyl Hydroxyethyl Cellulose (MHEC) ke motsoako oa cellulose ether o fumanang tšebeliso e atileng liindastering tse fapaneng ka lebaka la thepa ea eona e ikhethang le ts'ebetso ea eona. Mona ke ntho e 'ngoe le e' ngoe eo u lokelang ho e tseba ka Methyl Hydroxyethyl Cellulose (MHEC):

1. Sebopeho sa Lik'hemik'hale:

MHEC ke methyl ether ea hydroxyethyl cellulose, moo lihlopha tse peli tsa methyl (-CH3) le hydroxyethyl (-CH2CH2OH) li nkeloang sebaka sa mokokotlo oa cellulose. Sebopeho sena sa lik'hemik'hale se fana ka thepa e khethehileng ho MHEC, e etsa hore e be molemo mefuteng e fapaneng ea likopo.

2. Thepa:

a. Ho qhibiliha ha Metsi:

MHEC e qhibiliha ka metsing, e etsa litharollo tse hlakileng, tse hlakileng. Solubility le viscosity ea tharollo ea MHEC e itšetlehile ka lintlha tse kang boima ba limolek'hule, tekanyo ea ho fetola, le mocheso.

b. Ho tenya:

MHEC e sebetsa e le moemeli ea sebetsang hantle oa ho tenya litharollong tse nang le metsi. E fana ka boitšoaro ba pseudoplastic (shear-thinning), ho bolelang hore viscosity ea eona e fokotseha tlas'a khatello ea ho kuta. Thepa ena e na le molemo lits'ebetsong moo ho hlokahalang viscosity e tsitsitseng tlas'a maemo a sa tšoaneng.

c. Ho Etsa Lifilimi:

MHEC e na le thepa ea ho etsa lifilimi, e lumellang hore e thehe lifilimi tse feto-fetohang le tse momahaneng ha li omisoa. Lifilimi tsena li ka fana ka thepa ea lithibelo, ho khomarela, le tšireletso ho li-substrates lits'ebetsong tse fapaneng.

d. Paballo ea Metsi:

MHEC e bonts'a thepa ea ho boloka metsi, e thusang ho boloka maemo a mongobo ka har'a metsoako le li-substrates. Thepa ena e bohlokoa haholo linthong tsa kaho, moo ho hlokahalang metsi a nako e telele le ho sebetsa.

e. Khomarelo le Momahano:

MHEC e ntlafatsa ho khomarela le ho kopanya ha ho etsoa, ​​​​ho khothalletsa maqhama pakeng tsa likaroloana kapa libaka. E ntlafatsa ts'ebetso le ho tšoarella ha li-adhesives, li-coatings, le lihlahisoa tse ling tse entsoeng.

3. Likopo:

a. Lisebelisoa tsa Kaho:

MHEC e sebelisoa haholo linthong tsa kaho tse kang seretse, li-renders, grouts le li-adhesives tsa lithaele. E sebetsa e le motenya, moemeli oa ho boloka metsi, le mofetoleli oa rheology, ho ntlafatsa ts'ebetso, ho khomarela le ho tšoarella ha lihlahisoa tsa samente.

b. Lipente le Liaparo:

MHEC e eketsoa ho lipente tse thehiloeng metsing, lirafshoa le li-adhesives e le motenya le mofetoleli oa rheology. E ntlafatsa taolo ea viscosity, khanyetso ea sag, le sebopeho sa lifilimi, e lebisang ho koaheleng hantle le ho khomarela li-substrates tse fapaneng.

c. Lihlahisoa tsa Tlhokomelo ea Motho:

MHEC e fumanoa tlhokomelong ea botho le lihlahisoa tsa litlolo tse kang litlolo, litlolo, li-shampoo le li-gel. E sebetsa e le motenya, emulsifier, le stabilizer, e fana ka sebopeho, viscosity, le botsitso ho metsoako.

d. Meriana:

MHEC e sebelisoa mefuteng ea meriana e le setlamo se kopanyang, se senyang, le se laoloang-ho lokolloa ka matlapa le li-capsules. E ntlafatsa thepa ea letlapa joalo ka boima, sekhahla sa ho qhibiliha, le boemo ba ho lokolloa ha lithethefatsi.

Qetello:

Methyl Hydroxyethyl Cellulose (MHEC) ke ether ea cellulose e nang le mefuta e mengata e nang le mefuta e mengata ea thepa le lisebelisoa. Ho qhibiliha ha eona ha metsi, ho teteaneng, ho etsa lifilimi, ho boloka metsi, le thepa ea ho khomarela li etsa hore e be ea bohlokoa liindastering tse kang tsa kaho, lipente le liphahlo, tlhokomelo ea botho le meriana. E le tlatsetso e nang le mesebetsi e mengata, MHEC e kenya letsoho ts'ebetsong, ts'ebetsong, le ts'ebetsong ea lihlahisoa tse entsoeng ho pholletsa le mefuta e sa tšoaneng.
