Nk'ibikoresho bikunze gukoreshwa mu nganda zitandukanye, ifu ya eteri ya cellulose ifite ubushobozi bwo gufata neza, gukomera no kubika amazi. Ikoreshwa cyane mu bwubatsi, mu buvuzi, mu mavuta yo kwisiga, mu biribwa no mu bindi bikorwa byinshi. Ariko, kugira ngo ifu ya eteri ya cellulose igire umusaruro mwiza, hagomba kwitabwaho uburyo bwo kuyisesa. Dore ibintu by'ingenzi ugomba kuzirikana mu gihe usesa ifu ya eteri ya cellulose:
1. Hitamo umuti ukwiye wo gushonga
Ifu ya eteri ya selulosi irashonga cyane mu mazi, bigatuma habaho umuti ubonerana kandi urimo kugorama. Ariko, ubwoko butandukanye bwa eteri za selulosi bufite uburyo butandukanye bwo gushonga mu mazi, kandi uburyo bwo gushonga kwazo buzaterwa n'ibintu nk'ubushyuhe na pH. Kubwibyo, guhitamo umuti ukwiye kugira ngo ubone umusaruro mwiza ni ingenzi cyane.
Urugero, niba ifu ya ether ya cellulose ikeneye gushonga mu bushyuhe buke cyangwa muri sisitemu ya pH nke, hydroxypropylmethylcellulose (HPMC) cyangwa methylcellulose (MC) bishobora kuba byiza kurusha ethylcellulose (EC) cyangwa carboxylate Better Choice Methylcellulose (CMC). Ni ngombwa guhitamo solvent ikwiye ukurikije ibisabwa mu gukoresha n'imiterere y'solvent.
2. Kugenzura ubushyuhe
Ubushyuhe ni ikindi kintu cy'ingenzi bigira ingaruka ku gushonga kw'ifu ya eteri ya selulosi. Gushonga kwa eteri za selulosi kwiyongera uko ubushyuhe bugenda bushira, ariko n'umuvuduko wo gushonga ugenda ushira, bishobora gutuma habaho ifu zivanze cyangwa zivanze. Kubwibyo, ubushyuhe bugomba kugenzurwa neza mu gihe cyo gushonga.
Muri rusange, ubushyuhe bwiza bwo gushonga eteri ya selulosi ni 20-40°C. Iyo ubushyuhe buri hasi cyane, bishobora kuba ngombwa kongera igihe cyo gushonga cyangwa gukoresha solvent ikwiye. Iyo ubushyuhe buri hejuru cyane, bishobora gutuma eteri ya selulosi yangirika kandi bigagira ingaruka ku mikorere yayo.
3. Kangura hanyuma uvange
Gukangura no gukangura nabyo ni ingenzi mu gushonga ifu ya eteri ya cellulose. Gukangura neza bifasha ifu gukwirakwira neza mu gishongesho kandi bikarinda gushonga. Gukangura binafasha kongera umuvuduko wo gushonga, cyane cyane ku bisubizo bifite ubukana bwinshi.
Ariko, gukurura cyane bishobora gutera utubumbe tw’umwuka cyangwa ifuro, bishobora kugira ingaruka ku buryo umuti usobanutse neza kandi uhamye. Kubwibyo, ni ngombwa guhindura umuvuduko n’ubukana bw’ibyuka bikurura bitewe n’ibisabwa byihariye n’aho ifu ya eteri ya cellulose ikoreshwa.
4. Inyongeramusaruro
Inyongeramusaruro zishobora kongerwamo mu gihe cyo gushonga kw'ifu ya ether ya cellulose kugira ngo yongere imikorere cyangwa ihamye. Urugero, borax cyangwa ibindi bintu bya alkaline bishobora kongerwamo kugira ngo bihindure pH y'umuti no kongera ubukana. Sodium bicarbonate nayo yongera ubukana bw'umuti, bigatinda umuvuduko wo gushonga.
Izindi nyongeramusaruro nka surfactants, umunyu cyangwa polymers zishobora gukoreshwa mu kongera ubushobozi bwo gushonga, kudahungabana cyangwa izindi ngaruka z'umuti wa ether ya cellulose. Ariko, ni ngombwa gukoresha inyongeramusaruro mu rugero no guhitamo witonze, kuko inyongeramusaruro nyinshi cyangwa zitari nziza zishobora gutera ingaruka mbi zitari ngombwa.
5. Igihe cyo gusesa
Igihe cyo gusenya ni ikintu cy'ingenzi mu ikorwa n'ikoreshwa ry'ifu ya eteri ya selulosi. Igihe cyo gusenya giterwa n'ibintu byinshi nko ubwoko bwa eteri ya selulosi, solvent, ubushyuhe, umuvuduko wo gukurura n'ubwinshi.
Muri rusange, ifu ya ether ya cellulose igomba kongerwa muri solvent buhoro buhoro kandi buhoro buhoro uvanga buri gihe kugeza igihe habonetse umuti uhuye. Igihe cyo gushonga gishobora gutandukana kuva ku minota mike kugeza ku masaha menshi, bitewe n'ibintu byavuzwe haruguru.
Ni ngombwa gukurikirana witonze inzira yo gusenya no guhindura ibipimo uko bikenewe kugira ngo hamenyekane ubwiza n'ubuziranenge bw'umuti wa eteri ya selulose.
Mu gusoza, ifu ya eteri ya selulose ni ibikoresho bifite akamaro kandi bifite akamaro mu nganda zitandukanye. Ariko, inzira yo gusenya ni ingenzi kugira ngo igere ku musaruro mwiza. Mu kwita ku bintu nko guhitamo ibinyabutabire, kugenzura ubushyuhe, gukangura, inyongeramusaruro, n'igihe cyo gusenya, birashoboka kubona umuti wa eteri ya selulose wujuje ibisabwa mu ikoreshwa.
