Lintho tsa 'Mele le Lik'hemik'hale tsa Hydroxyethyl Cellulose

Hydroxyethyl Cellulose (HEC) ke polima e qhibilihang ka metsing e nang le thepa e ikhethang ea 'mele le ea lik'hemik'hale e e etsang hore e be molemo lits'ebetsong tse fapaneng tsa indasteri le tsa khoebo. Mona ke lintlha tsa bohlokoa tsa 'mele le tsa lik'hemik'hale tsa HEC:

Thepa ea Sebele:

1. Ponahalo: HEC hangata ke phofo e tšoeu ho isa ho e tšoeu, e sa nkhang hamonate, e sa latsoeheng, kapa granule. E ka fapana ka boholo ba likaroloana le boima ba 'mele ho latela mokhoa oa tlhahiso le kereiti.
2. Solubility: HEC e qhibiliha haholo ka metsing, e etsa litharollo tse hlakileng, tse hlakileng. The solubility ea HEC e ka 'na ea fapana le tekanyo ea ho fetola (DS) ea lihlopha tsa hydroxyethyl mokokotlong oa cellulose.
3. Viscosity: Litharollo tsa HEC li bonts'a pseudoplastic rheology, ho bolelang hore viscosity ea bona e fokotseha ka sekhahla sa ho kuta. The viscosity ea litharollo tsa HEC e ka fetoloa ka ho fapanyetsana mahloriso a polymer, boima ba limolek'hule, le tekanyo ea ho kenya sebaka.
4. Tlhahiso ea Lifilimi: HEC e etsa lifilimi tse feto-fetohang le tse hlakileng ha li omisitsoe, li fana ka thepa ea thibelo le ho khomarela holimo. Bokhoni ba ho etsa lifilimi ba HEC bo kenya letsoho ts'ebelisong ea eona ea ho roala, likhomaretsi le lihlahisoa tsa tlhokomelo ea motho.
5. Ho boloka Metsi: HEC e na le matla a phahameng a ho boloka metsi, e lelefatsang ts'ebetso ea hydration ka liforomo tse joalo ka lisebelisoa tsa samente, likhomaretsi le liphahlo. Thepa ena e ntlafatsa ho sebetsa, ho khomarela, le ho beha nako ka ho boloka maemo a mongobo le ho thibela tahlehelo e potlakileng ea metsi.
6. 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.

Lintho tsa Lik'hemik'hale:

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. Ho se Fellehe ha Lik'hemik'hale: HEC ha e sebetse ka lik'hemik'hale 'me e lumellana le mefuta e mengata ea metsoako, 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.
3. Biodegradability: HEC e tsoa mehloling ea selulose e nchafalitsoeng 'me e khona ho senyeha, ho e etsa hore e se ke ea silafatsa tikoloho. E arola likarolo tsa tlhaho tlas'a ts'ebetso ea likokoana-hloko, e fokotsa tšusumetso ea tikoloho le ho khothalletsa ho tšoarella.
4. Ho lumellana: HEC e lumellana le mefuta e meng ea li-polymers, li-additives, le metsoako e atisang ho sebelisoa ha ho etsoa liindasteri. Ho tsamaellana ha eona ho lumella hore ho be le moralo o feto-fetohang oa sebopeho le mokhoa oa hau ho fihlela litlhoko tse ikhethileng tsa kopo.

Ka kakaretso, Hydroxyethyl Cellulose (HEC) e bonts'a thepa e ikhethang ea 'mele le ea lik'hemik'hale e etsang hore e be tlatsetso ea bohlokoa lits'ebetsong tse ngata, ho kenyeletsoa kaho, lipente le liphahlo, likhomaretsi, litlolo, litlhare, masela le tlhokomelo ea motho. Ho qhibiliha ha eona, ho hlaka ha eona, ho boloka metsi, bokhoni ba ho etsa lifilimi, le ho lumellana ha eona ho kenya letsoho ho feto-fetoheng ha eona le ho sebetsa ha eona mekhoeng le lihlahisoa tse fapaneng.
