Malebela a ho Hlela Hydrating Hydroxyethyl Cellulose (HEC)

Hydroxyethyl cellulose (HEC) ke polima e qhibilihang ka metsi e atisang ho sebelisoa liindastering tse fapaneng bakeng sa thepa ea eona e teteaneng, e tsitsitseng le ea ho etsa lifilimi. Ha o sebetsa le HEC, ho etsa bonnete ba hore ho na le metsi a nepahetseng ho bohlokoa ho fihlela ts'ebetso e lakatsehang ho liforomo. Malebela ke ana a ho nosetsa HEC ka katleho:

1. Sebelisa Metsi a Silafetseng: Qala ka ho sebelisa metsi a silafetseng kapa metsi a hloekisitsoeng bakeng sa hydrating HEC. Litšila kapa li-ion tse teng metsing a pompo li ka ama ts'ebetso ea hydration mme li ka lebisa liphellong tse sa tsitsang.
2. Mokhoa oa ho itokisa: Ho na le mekhoa e fapaneng ea ho futhumatsa HEC, ho kenyelletsa ho kopanya ho bata le ho kopanya ho chesang. Ka ho kopanya ho batang, HEC e kenngoa butle-butle metsing ka ho tsosoa ho tsoelang pele ho fihlela e qhalakane ka ho feletseng. Ho kopanya ho chesang ho kenyelletsa ho futhumatsa metsi ho pota 80-90 ° C ebe o eketsa butle-butle HEC ha u ntse u hlohlelletsa ho fihlela metsi a feletseng. Khetho ea mokhoa o itšetlehile ka litlhoko tse khethehileng tsa tlhahiso.
3. Keketso ea Butle-butle: Ho sa tsotellehe hore na ho sebelisa motsoako o batang kapa ho kopanya ho chesang, ho bohlokoa ho eketsa HEC butle-butle metsing ha u ntse u tsoela pele ho sisinyeha. Sena se thusa ho thibela ho thehoa ha maqhubu le ho etsa bonnete ba ho hasana ho tšoanang ha likaroloana tsa polymer.
4. Ho susumetsa: Ho hlohlelletsa hantle ho bohlokoa bakeng sa ho nosetsa HEC hantle. Sebelisa mochini o hlasimollang kapa motsoako o phahameng oa ho kuta ho etsa bonnete ba ho hasana ka ho feletseng le ho phalla ha polymer. Qoba ho sebelisa pherekano e feteletseng, kaha e ka hlahisa li-bubble tsa moea tharollong.
5. Nako ea Hydration: Lumella nako e lekaneng ea hore HEC e noe metsi ka botlalo. Ho itšetlehile ka sehlopha sa HEC le mokhoa oa hydration o sebelisitsoeng, sena se ka tloha metsotso e 'maloa ho ea ho lihora tse' maloa. Latela likhothaletso tsa moetsi bakeng sa kereiti e ikhethileng ea HEC e sebelisoang.
6. Taolo ea Mocheso: Ha u sebelisa motsoako o chesang, shebella mocheso oa metsi ka hloko ho thibela mocheso o feteletseng, o ka senyang polima. Boloka mocheso oa metsi ka har'a mefuta e khothalletsoang ho pholletsa le ts'ebetso ea hydration.
7. Phetoho ea pH: Ka mekhoa e meng, ho fetola pH ea metsi pele u eketsa HEC ho ka ntlafatsa metsi. Buisana le moetsi oa lihlahisoa kapa u bue ka lintlha tsa sehlahisoa bakeng sa tataiso mabapi le tokiso ea pH, ha ho hlokahala.
8. Teko le Tokiso: Ka mor'a hydration, leka viscosity le ho tsitsa ha tharollo ea HEC ho netefatsa hore e kopana le litlhaloso tse lakatsehang. Haeba ho hlokahala liphetoho, metsi a eketsehileng kapa HEC a ka eketsoa butle-butle ha a ntse a hlohlelletsa ho finyella thepa e lakatsehang.

Ka ho latela malebela ana, o ka etsa bonnete ba hore hydroxyethyl cellulose (HEC) e na le hydration e nepahetseng le ho ntlafatsa ts'ebetso ea eona mekhoeng ea hau.
