HEC bakeng sa Lesela

Hydroxyethyl cellulose (HEC) e sebelisoa haholo indastering ea masela, e bapala karolo ea bohlokoa lits'ebetsong tse fapaneng ho tloha phetohong ea faeba le lesela ho isa ho etseng li-paste tsa khatiso. Mona ke kakaretso ea lits'ebetso, mesebetsi le lintho tse nahanoang ka HEC maemong a masela:

1. Selelekela sa Hydroxyethyl Cellulose (HEC) ho Masela

1.1 Tlhaloso le Mohloli

Hydroxyethyl cellulose ke polymer e qhibilihang ka metsing e nkiloeng ho cellulose ka karabelo le ethylene oxide. Hangata e fumanoa ho tsoa ho pulp ea lehong kapa k'hothone 'me e sebetsoa ho etsa polymer e nang le thepa e ikhethang ea rheological le ea ho etsa filimi.

1.2 Ho Feto-fetoha ha Lisebelisoa tsa Masela

Indastering ea masela, HEC e fumana lits'ebetso mekhahlelong e fapaneng ea tlhahiso, e tlatsetsang ts'ebetsong, qetellong le phetohong ea likhoele le masela.

2. Mesebetsi ea Hydroxyethyl Cellulose ho Masela

2.1 Ho tenya le ho Tsitsisa

HEC e sebetsa e le sesebelisoa sa ho teteana le ho tsitsisa ho daeng le ho hatiseng li-pesta, e ntlafatsa ho teteana ha tsona le ho thibela ho senngoa ha likaroloana tsa dae. Sena se bohlokoa bakeng sa ho fihlela 'mala o ts'oanang le o tsitsitseng masela.

2.2 Sebopeho sa ho Printa Peista

Khatisong ea masela, HEC e atisa ho sebelisoa ho etsa li-paste tse hatisitsoeng. E fana ka thepa e ntle ea rheological ho peista, e lumellang ho sebelisoa ha lidae ka nepo masela nakong ea ts'ebetso ea khatiso.

2.3 Phetoho ea Faeba

HEC e ka sebelisoa bakeng sa phetoho ea faeba, e fanang ka litšobotsi tse itseng ho lifaeba tse kang matla a ntlafetseng, ho tenyetseha, kapa ho hanyetsa ho senyeha ha likokoana-hloko.

2.4 Ho Boloka Metsi

HEC e ntlafatsa ho boloka metsi mefuteng ea masela, e leng se etsang hore e be molemo lits'ebetsong tseo ho tsona ho boloka maemo a mongobo ho leng bohlokoa, joalo ka linthong tse lekanyang boholo kapa lipeista bakeng sa khatiso ea lesela.

3. Litšebeliso ho Masela

3.1 Ho Hatisa le ho Daea

3.2 Li-agent tsa Saese

Ha ho etsoa boholo, HEC e thusa ho tsitsisa le ho teteana ha tharollo ea boholo, e thusa ho sebelisa boholo ba khoele e kobehileng ho ntlafatsa matla a eona le ho loha habonolo.

3.3 Baemeli ba ho Qetela

HEC e sebelisoa linthong tsa ho qeta ho fetola litšobotsi tsa masela, joalo ka ho ntlafatsa maikutlo a 'ona, ho ntlafatsa ho hanyetsa matheba, kapa ho eketsa litšobotsi tse ling tse sebetsang.

3.4 Lidae tse arabelang ka faeba

HEC e tsamaisana le mefuta e fapaneng ea dae, ho kenyeletsoa le dae tse sebetsang ka faeba. E thusa kabong e lekanang le ho tiisa dae tsena holim'a likhoele nakong ea ts'ebetso ea dae.

4. Lintho Tse Lokelang ho Etsoa Mehopolo le Litlhokomelo

4.1 Ho tsepamisa maikutlo

Ho bokellana ha HEC mefuteng ea masela ho lokela ho laoloa ka hloko ho fihlela litšobotsi tse lakatsehang tsa rheological ntle le ho ama litšobotsi tsa sehlahisoa sa masela hampe.

4.2 Ho lumellana

Ho bohlokoa ho netefatsa hore HEC e lumellana le lik'hemik'hale tse ling le lintho tse ling tse sebelisoang lits'ebetsong tsa masela ho qoba mathata a kang ho phaphamala, ho fokotseha ha katleho, kapa liphetoho sebopehong.

4.3 Tšusumetso ea Tikoloho

Ho lokela ho nahaneloa tšusumetso ea tikoloho ea lits'ebetso tsa masela, 'me ho lokela ho etsoa boiteko ba ho khetha likhetho tse tsitsitseng le tse sireletsang tikoloho ha ho etsoa ka HEC.

5. Qetello

Hydroxyethyl cellulose ke setlolo se ka sebelisoang indastering ea masela, se tlatsetsang lits'ebetsong tse kang ho hatisa, ho daea, ho lekanya boholo le ho qeta. Matla a eona a rheological le a ho boloka metsi a etsa hore e be ea bohlokoa ho etseng li-paste le litharollo tse sebelisoang lits'ebetsong tse fapaneng tsa masela. Baqapi ba lokela ho nahana ka hloko ka mahloriso, ho lumellana le lintlha tsa tikoloho ho netefatsa hore HEC e eketsa melemo ea eona mefuteng e fapaneng ea masela.
