Malebela a Hydration Hydroxethyl celloulose (Hec)

Hydroxethyl celdlouseyeyl ke polymer ea quadmer eo e sebelisoang ka metsing e sebelisoang hangata indastering ea eona e fapaneng bakeng sa eona ea moea, e tsitsitseng, le ho etsa lifilimi tse etsang filimi. Ha u sebetsa le Hc, netefatsa hore ho bohlokoa ho bohlokoa ho fihlela ts'ebetso e lakatsehang e le lifoleng. Malebela a bona ke a hydrap hec hantle:

1. Sebelisa metsi a hlokofalitsoeng: Qala ka ho sebelisa metsi a behiloeng kapa a sentsoeng bakeng sa hōle HEC. Litšitiso kapa lihlekehleke tse teng ka metsing a pompo ho ka ama mokhoa oa ho hloekisa 'me o ka lebisa liphellong tse sa lumellaneng.
2. Mokhoa o hlophisehileng: Ho na le mekhoa e fapaneng ea ho h to fac, ho kenyelletsa ho kopanya ho bata le ho kopanya ho kopanya. Ha a ntse a kopanya, butle-butle HEC o ile a eketsa metsi ka matla a tsoelang pele ho fihlela a hasoa ka botlalo. Ho kopanya ho kopanya ho kenyelletsa ho futhumatsa metsi ho fihlela a 80-90 ° C hape ebe o eketsa Hec a hlohlelletsa hec a hlohlelletso. Khetho ea mokhoa o ipapisitse le litlhoko tse ikhethileng tsa sebopeho.
3. Tlhahiso-leseling: Ho kopanya ho bata kapa ho chesa ho kopanya kapa ho bohlokoa ho eketsa hore Ec butle butle ho ea ka tšohanyetso. Sena se thusa ho thibela ho etsoa ha likhalase 'me se netefatse ho hana lintho tse fapaneng tsa likaroloana tsa polymer.
4. Ho susumetsoa: Ho hlohlelletsa ka nepo ho bohlokoa bakeng sa hydrable hec ka katleho. Sebelisa mongoli oa mochini kapa mongoli ea phahameng haholo ho netefatsa ho fokola ka botlalo le hydration ea polymer. Qoba ho sebelisa ho ferekana ho feteletseng, kaha e ka hlahisa lihlomo tsa moea ka tharollo.
5. Nako ea Heldration: Lumella nako e lekaneng ea hore Hec e hlterate ka botlalo. Ho latela sehlopha sa Hec le mokhoa oa Hydration o sebelisoang, sena se ka tloha ka metsotso e 'maloa ho fihlela lihora tse' maloa. Latela likhothaletso tsa moetsi bakeng sa sehlopha se itseng sa hec.
6. Taolo ea mocheso: Ha u ntse u sebelisa ho tsoa hamonate, ho hlokomela mocheso oa metsi ka hloko ho thibela polymar, e ka nyenyefatsang polymer. Boloka mocheso oa metsi kahare ho moo o khothalletsoang ho pholletsa le tokiso ea toma.
7. Phetoho: Lihlopheng tse ling, ho lokisa PH ea metsi pele u eketsa HEC ho ka ntlafatsa hydration. Buisana le foromo kapa ho sheba litlhaloso tsa lihlahisoa bakeng sa tataiso ho PH phetoho, haeba ho hlokahala.
8. Ho etsa tlhahlobo le liphetoho: Kamora ho hlophisoa, kamora ho hlahloba viscosity le mokhoa oa ho etsa tharollo ea hec ho netefatsa litlhaloso tse utsoitseng. Haeba ho hlokahala liphetoho, metsi a eketsehileng kapa hec a ka eketsoa butle butle ha a ntse a hlohlelletsa ho fihlela thepa e lakatsehang.

Ka ho latela likeletso tsena, u ka netefatsa hydroyethyl celdoulose (Hec) le ho ntlafatsa ts'ebetso ea eona ho liforomo tsa hau.
