Nkibikoresho bisanzwe bikoreshwa mubikorwa bitandukanye, ifu ya selulose ether ifata neza, kubyimba no kubika amazi. Byakoreshejwe cyane mubwubatsi, ubuvuzi, kwisiga, ibiryo nibindi byinshi. Ariko, kugirango ubone imikorere myiza ivuye muri selulose ether ifu, hagomba kwitonderwa uburyo bwo gusesa. Dore ibintu bimwe byingenzi ugomba gusuzuma mugihe ushonga ifu ya selile ether:
1. Hitamo igisubizo gikwiye
Ifu ya selulose ether irashonga cyane mumazi, ikora igisubizo kiboneye, kibonerana. Nyamara, ubwoko butandukanye bwa selile ya selile ifite imbaraga zitandukanye mumazi, kandi gukomera kwayo bizaterwa nibintu nkubushyuhe na pH. Kubwibyo, guhitamo igisubizo gikwiye kubisubizo byiza ni ngombwa.
Kurugero, niba ifu ya selulose ether ikeneye gushonga mubushyuhe buke cyangwa muri sisitemu ya pH nkeya, hydroxypropylmethylcellulose (HPMC) cyangwa methylcellulose (MC) irashobora kuba nziza kuruta Ethylcellulose (EC) cyangwa carboxylate Nziza Guhitamo Methylcellulose (CMC). Ni ngombwa guhitamo igisubizo gikwiye urebye ibisabwa nibisabwa hamwe nibisabwa.
2. Kugenzura ubushyuhe
Ubushyuhe ni ikindi kintu cyingenzi kigira ingaruka ku iseswa rya puderi ya selile. Ububasha bwa selile ya selile yiyongera hamwe nubushyuhe, ariko rero nigipimo cyo gusesa, gishobora gutera ifu ya agglomerated cyangwa agglomerated. Kubwibyo, ubushyuhe bugomba kugenzurwa neza mugihe cyo gusesa.
Muri rusange, ubushyuhe bwiza bwo gushonga selulose ether ni 20-40 ° C. Niba ubushyuhe buri hasi cyane, birashobora kuba nkenerwa kongera igihe cyo gusesa cyangwa gukoresha igisubizo gikwiye. Niba ubushyuhe buri hejuru cyane, burashobora gutera kwangirika kwa selile kandi bigira ingaruka kumikorere.
3. Kangura kandi ubyuke
Gukangura no guhagarika umutima nabyo ni ngombwa mugihe ushonga ifu ya selile. Imyitozo ikwiye ifasha ifu gutatana neza mumashanyarazi kandi ikarinda guhuzagurika. Gukangura bifasha kandi kongera umuvuduko wo guseswa, cyane cyane kubisubizo bihanitse cyane.
Nyamara, guhagarika umutima cyane bishobora kubyara umwuka mwinshi cyangwa ifuro, bishobora kugira ingaruka kumyumvire no gutuza kwumuti. Niyo mpamvu, birakenewe guhindura umuvuduko ukabije hamwe nimbaraga ukurikije ibisabwa byihariye hamwe nibidukikije bya porojeri ya selile.
4. Inyongera
Inyongeramusaruro zirashobora kongerwaho mugihe cyo gusesa ifu ya selile ether kugirango yongere imikorere cyangwa ituze. Kurugero, borax cyangwa ibindi bintu bya alkaline birashobora kongerwaho kugirango uhindure pH yumuti kandi wongere ubwiza. Sodium bicarbonate nayo yongerera ubwiza bwumuti, igabanya umuvuduko wo gushonga.
Ibindi byongeweho nka surfactants, umunyu cyangwa polymers birashobora gukoreshwa mugutezimbere, gutuza cyangwa indi miterere yumuti wa selile. Nyamara, ni ngombwa gukoresha inyongeramusaruro mu rugero hanyuma ugahitamo witonze, kuko inyongera zirenze cyangwa zidakwiye zishobora gutera ingaruka zitifuzwa.
5. Gukuraho igihe
Igihe cyo gusesa nikintu cyingenzi mugukora no gukoresha ifu ya selile. Igihe cyo guseswa biterwa nibintu byinshi nkubwoko bwa selile ya ether, solvent, ubushyuhe, kubyutsa umuvuduko no kwibanda.
Muri rusange, ifu ya selulose ether igomba kongerwaho umusemburo gahoro gahoro hamwe no guhora bivanga kugeza habonetse igisubizo kimwe. Ibihe byo gutandukana birashobora gutandukana muminota mike kugeza kumasaha menshi, bitewe nibintu byavuzwe haruguru.
Ni ngombwa gukurikirana witonze inzira yo gusesa no guhindura ibipimo nkibikenewe kugirango hamenyekane ubuziranenge nuburinganire bwumuti wa selile.
Mu gusoza, ifu ya selulose ether ni ibintu byinshi kandi bifite agaciro mubikorwa bitandukanye byinganda. Nyamara, inzira yo gusesa ni ngombwa kugirango igere ku mikorere yayo myiza. Mu kwitondera ibintu nko guhitamo ibisubizo, kugenzura ubushyuhe, gukurura, inyongeramusaruro, nigihe cyo gusesa, birashoboka kubona igisubizo cyiza cya selile cyiza cya ether cyujuje ibisabwa.
