Hydroxethyl Ceyulose (Hec) e sebelisoa haholo indasteri e fapaneng ka lebaka la thepa ea eona e ikhethang e kang ho boloka metsi. Ho phahama ha Hec hantle ho bohlokoa ho netefatsa ts'ebeliso ea eona e sebetsang likopo tse kang pente, litlolo, merati le thepa ea kaho.
1. Ho utloisisa hydroxethyl celdoulose (Hec):
Hec ke ngaka e seng ionic, ea nang le metsi e qhibilihang ea metsi e tsoa ho Cellloulose.
E bapala tharollo e hlakileng ka metsing, e bontša boitšoaro ba pseudopro, ba bolelang hore lipono tsa eona bo fokotseha ka sekhahla se ntseng se eketseha.
2. Khetho ea solvent:
Metsi ke boima bo atileng haholo bakeng sa ho phahamisoa ka lebaka la litsiso tsa eona tse phahameng.
Mocheso le ph ea solvent e ka susumetsa ho senyeha ha hec. Ka tloaelo, ho se nke lehlakore ho feta ka theko e nyane.
3. Ho lokisa mekhabiso e sa laoleheng:
Sebelisa metsi a bolokiloeng kapa a se a phelisitsoeng ho fokotsa liphoso tse ka amang likhoho tsa hec.
Boloka mocheso o lakatsang bakeng sa ts'ebetso ea ho qhala, hangata mocheso oa kamore e le mocheso o phahameng ka hanyane (ho pota 20-40 ° C).
4. Mekhoa ea ho lahla:
a. Ho Kopana Hand:
- E loketse lits'ebetso tse nyane tse nyane.
- Butle-butle eketsa ac phofo ho ea solvent ha u ntse u tsikinyeha ho thibela ho phunya.
- netefatsa ho koloba ka botlalo ka phofo pele u eketsa botebo.
b. Mochini o susumetsang:
- Sebelisa seretse se nang le mochini o nang le lehare le loketseng kapa mochoti.
- Fetola lebelo la ho tsitsipanya ho fihlela ho hloella jwaloka ho bakang ho baka bofokoli bo feteletseng kapa ho phekola moea.
c. Ho kopanya ho hongata haholo:
- Sebelisa motsoako o phahameng joalo ka li-homozeges kapa li hasahlo ka lebelo le phahameng bakeng sa ho hlorisoa hantle.
- laola sekhahla sa shear ho thibela ho nyonya ha limolek'hule tsa Hec.
d. Ultranon:
- Sebelisa matla a ultrasonic ho ea tlase agglomerate le ho ntlafatsa ho hasaha.
- Etsa bonnete ba hore na litekanyetso tsa Boriloe (Khafetsa, ho lieha, ho qoba ho senya kapa ho nyenyefatsa tharollo kapa ho nyenyefatsa tharollo.
5. Malebela a ho hasanya Phetoho:
Etsa bonnete ba hore phofo ea Hec e eketsoa butle-butle ho thibela sebopeho sa khampani.
Qoba liphetoho tsa tšohanyetso ka mocheso kapa u ipolaea, kaha li ka amang qhobosheane ea hec.
Fana ka nako e lekaneng ea hydrate e felletseng le ho hasana ha likaroloana tsa hec.
Hlokomela lipono tsa pono nakong ea ho lahla ho fihlela maemo a lakatsehang.
Sebelisa lisebelisoa le mekhoa e nepahetseng ho latela tekanyo le litlhokahalo tsa kopo.
6. Taolo ea boleng:
Etsa tlhahlobo ea bonono bakeng sa likaroloana tse sa laoloang kapa mekhoa e kang ea gel.
Lekanya Viscosity u sebelisa viceter ho netefatsa ho etsa lintho tse lumellanang le litlhaloso tse lakatsehang.
Tsamaea liteko tsa Rheology ho lekola boitšoaro ba ho phalla le botsitso ba hec.
7. Boloka le ho sebetsana le tsona:
Boloka Hec Ho hasanya Hec Hactiers e hloekile, e besitsoeng ka thata ho thibela tšilafalo le mongobo oa mongobo.
Qoba ho pepesetsoa ha nako e telele ho lithemparetjha tse feteletseng kapa khanya ea letsatsi, e ka fokolisang polymer.
Lijana tsa Label tse nang le tlhaiso-leseling e nepahetseng ho kenyelletsa la batch, ho tsepamisa maikutlo le maemo a polokelo.
8. Mehopolo ea polokeho:
Latela litataiso tsa polokeho ha li sebetsana le phofo ea Hec le tharollo.
Sebelisa lisebelisoa tse loketseng tsa ts'ireletso (PPE) joalo ka liatlana le li-google tsa polokeho.
Qoba ho inhalane ka likaroloana tsa lerōle ka ho sebetsa sebakeng se nang le moea o lekaneng kapa ho sebelisa tšireletso ea phefumoloho haeba ho hlokahala.
Ho phahama ha hydrothyl ho hloka ho hlahloba ka hloko ka khetho, mekhoa ea taolo ea boleng le mehato ea matla. Ka ho latela litataiso tsena, u ka netefatsa ts'ebetso e nepahetseng le botsitso ba hec e sebetsang likopo tse fapaneng tsa indasteri ea indasteri.
