Selelekela sa Hydroxyethyl Cellulose

Hydroxyethyl Cellulose (HEC) ke polima e se nang ionic, e qhibilihang ka metsing e tsoang ho cellulose, polima ea tlhaho e fumanoang limela. HEC e sebelisoa haholo liindastering tse fapaneng ka lebaka la thepa ea eona e ikhethang le lits'ebetso tse fapaneng. Mona ke kenyelletso ea Hydroxyethyl Cellulose:

1. Sebopeho sa Lik'hemik'hale:

• HEC ke cellulose ether e fetotsoeng ka lihlopha tsa hydroxyethyl. E hlahisoa ka ho arabela cellulose ka ethylene oxide tlas'a maemo a laoloang. Tekanyo ea ho kenya sebaka (DS) ea lihlopha tsa hydroxyethyl mokokotlong oa cellulose e lekanya thepa le ts'ebetso ea HEC.

2. Thepa ea 'Mele:

• HEC ke phofo kapa granule e tšoeu ho isa ho bosoeu, ha e nkha, ebile e sa latsoehe. E qhibiliha ka metsing 'me e etsa litharollo tse hlakileng, tse hlakileng tse nang le pseudoplastic rheology. The viscosity ea litharollo tsa HEC e ka fetoloa ka ho fapanyetsana mahloriso a polymer, degree of substitution, le boima ba molek'hule.

3. Lintho tsa Rheological:

• HEC e bonts'a thepa e ntle ea ho tenya le ea rheological, e e etsa hore e be motenya o sebetsang hantle, o tsitsitseng, le oa pele oa lifilimi lits'ebetsong tse fapaneng. E fana ka boitšoaro ba pseudoplastic, ho bolelang hore viscosity ea eona e fokotseha ka sekhahla sa ho kuta, e lumellang ho sebelisoa habonolo le ho hasana.

4. Paballo ea Metsi:

• HEC e na le matla a phahameng a ho boloka metsi, e lelefatsang ts'ebetso ea hydration ka liforomo tse kang lisebelisoa tsa samente, li-adhesives le liphahlo. E ntlafatsa ho sebetsa, ho khomarela, le ho beha nako ka ho boloka maemo a mongobo le ho thibela tahlehelo e potlakileng ea metsi.

5. Phokotso ea Khatello ea Bokahohle:

• HEC e fokotsa tsitsipano ea holim'a metsi a entsoeng ka metsi, ho ntlafatsa ho kolobisa, ho hasana, le ho lumellana le li-additives le li-substrates tse ling. Thepa ena e ntlafatsa ts'ebetso le botsitso ba libopeho, haholo-holo ka li-emulsions le li-suspensions.

6. Botsitso le Kamano:

• HEC ha e sebetse ka lik'hemik'hale 'me e lumellana le mefuta e mengata ea lisebelisoa tse ling, ho akarelletsa le li-surfactants, letsoai, acid le alkalis. E lula e tsitsitse holim'a mefuta e mengata ea pH le mocheso, e netefatsa ts'ebetso e tsitsitseng mekhoeng le lits'ebetsong tse fapaneng.

7. Tlhahiso ea lifilimi:

• HEC e etsa lifilimi tse feto-fetohang, tse hlakileng ha li omisitsoe, li fana ka thepa ea thibelo le ho khomarela holimo. E sebelisoa e le moemeli oa ho etsa lifilimi ka liphahlo, li-adhesive, lihlahisoa tsa tlhokomelo ea botho, le lihlahisoa tsa meriana, ho ntlafatsa nako e telele le boipiletso bo botle.

8. Likopo:

• HEC e fumana lits'ebetso tse fapaneng liindastering tse joalo ka kaho, lipente le liphahlo, likhomaretsi, litlolo, litlhare, masela le tlhokomelo ea motho. E sebelisoa e le motenya, rheology modifier, e boloka metsi, stabilizer, filimi-former, le binder mefuteng e fapaneng ea lihlahisoa le lihlahisoa.

9. Maikutlo a Tikoloho le Polokeho:

• HEC e tsoa mehloling ea selulose e nchafalitsoeng 'me e khona ho senyeha, ho e etsa hore e se ke ea silafatsa tikoloho. E nkoa e sireletsehile bakeng sa tšebeliso ea lihlahisoa tsa bareki 'me e lumellana le litlhoko tsa taolo le litekanyetso tsa boleng linaheng tse fapaneng.

Ka bokhutšoanyane, Hydroxyethyl Cellulose (HEC) ke polymer e feto-fetohang le e sebelisoang haholo e nang le botenya bo botle, ho boloka metsi, rheological, le thepa ea ho etsa lifilimi. Lisebelisoa tsa eona tse fapaneng le ho tsamaellana le li-additives tse ling li e etsa motsoako oa bohlokoa mekhoeng le lihlahisoa tse ngata ho pholletsa le liindasteri.
