Ethers ya selile ni urwego rwa polymers ikomoka kuri selile, polyisikaride isanzwe iboneka mubihingwa. Nibyingenzi mubikorwa byinganda bitewe nuburyo butandukanye hamwe nibikorwa byinshi mubikorwa bitandukanye.
1. Ibyiza bya Cellulose Ethers:
Ethers ya Cellulose yerekana imitungo myinshi ihesha agaciro mubikorwa byinganda:
Amazi ya Solubility: Ethers ya selile ikunze gushonga amazi cyangwa irashobora guhagarika ihagarikwa ryamazi mumazi, bigatuma ikoreshwa muburyo butandukanye bwo gukoresha amazi.
Imiterere ya firime: Bafite ubushobozi bwo gukora firime zoroshye, zibonerana, zikagira akamaro nkibifuniko.
Kubyimba no Kuzunguruka: Ethers ya selile irashobora kongera ibisubizo no gukora geles, ifite akamaro munganda nkibiryo, imiti, no kwita kubantu.
Igihagararo: Zitanga umutekano mukurwanya kwangirika kwa mikorobe hamwe nubushakashatsi bwimiti, byongera ubuzima bwibicuruzwa bikoreshwa.
2. Uburyo bwo gukora:
Ether ya selile isanzwe ikorwa hifashishijwe imiti ihindura selile. Uburyo busanzwe burimo etherification na esterification reaction, aho amatsinda ya hydroxyl kuri molekile ya selile asimbuzwa ether cyangwa ester groupe. Izi reaction zirashobora gukorwa hifashishijwe reagent zitandukanye na catalizator, bikavamo ethers ya selile ifite imiterere nibikorwa bitandukanye.
Igikorwa cyo gukora kirimo intambwe nyinshi:
Isuku rya Cellulose: Cellulose ikurwa mumasoko y'ibimera nk'ibiti by'ibiti cyangwa ipamba hanyuma bigasukurwa kugirango bikureho umwanda.
Guhindura imiti: selile isukuye noneho ikorerwa etherification cyangwa esterification reaction yo kumenyekanisha amatsinda ya ether cyangwa ester.
Kweza no Kuma: Cellulose yahinduwe isukurwa kugirango ikureho ibicuruzwa n’ibindi byanduye, hanyuma ikumishwa kugirango ibone ibicuruzwa bya selile ya nyuma.
3. Gusaba Inganda:
Ether ya selile isanga ikoreshwa cyane mubikorwa bitandukanye, harimo:
Ubwubatsi: Mu nganda zubaka, ethers ya selile ikoreshwa nkibibyimbye muri minisiteri ishingiye kuri sima na plasta kugirango bitezimbere imikorere, gufata amazi, no gufatira hamwe. Bakora kandi nk'ibihindura imvugo, bikazamura uburinganire n'ubwuzuzanye bw'ibikoresho byo kubaka.
Ibiribwa n'ibinyobwa: Ethers ya selile ikoreshwa nk'ibibyimba, stabilisateur, na emulisiferi mu biribwa n'ibinyobwa nk'isosi, imyambarire, n'ibikomoka ku mata. Bafasha kunoza imiterere, ubwiza, hamwe numunwa mugihe banarinda gutandukanya ibintu.
Imiti ya farumasi: Muburyo bwa farumasi, ether ya selile ikora nka binders, disintegrants, hamwe nubushakashatsi bugenzura-ibinini na capsules. Zitanga ubunyangamugayo kumiterere ya dosiye, koroshya ibiyobyabwenge, no kugenzura igipimo cyo kurekura ibiyobyabwenge.
Ibicuruzwa byita ku muntu ku giti cye: Ethers ya selile ikunze kuboneka mubicuruzwa byita ku muntu nko kwisiga, ubwiherero, hamwe no kuvura uruhu. Bakora nkibibyimbye, stabilisateur, hamwe nabashinzwe gukora firime, batanga ibyifuzwa byifuzwa, ubwiza, nibintu byunvikana kubicuruzwa.
Irangi hamwe na Coatings: Mu nganda zo gusiga amarangi no gutwikira, ether ya selile ikoreshwa nka moderi ihindura rheologiya hamwe nubushakashatsi bwimbitse kugirango igabanye ububobere, kwirinda kugabanuka, no kunoza amarangi no kuringaniza. Zongera kandi gukomera no kuramba.
Imyenda: Ethers ya selile ikoreshwa mugucapura imyenda no gusiga amarangi nkibibyimbye kandi bihindura viscosity. Bafasha kugera kuburinganire nubusobanuro mugucapura no gusiga amarangi mugihe banongera amabara yihuta nimbaraga.
4. Ibidukikije no Kuramba Ibitekerezo:
Ether ya selulose ikomoka kubikoresho bishobora kuvugururwa, bigatuma ibidukikije byangiza ibidukikije kuri polymrike ya sintetike ikomoka kuri peteroli. Ikigeretse kuri ibyo, birashobora kwangirika kandi bidafite uburozi, bitera ingaruka nkeya kubidukikije mugihe cyo gukoresha no kujugunya. Imikoreshereze yabo mubikorwa bitandukanye irashobora kugira uruhare mu ntego zirambye mu kugabanya gushingira ku bicanwa biva mu kirere no kugabanya ingaruka z’ibidukikije.
5. Umwanzuro:
selile ya selile igira uruhare runini mubikorwa bitandukanye bitewe nimiterere yihariye hamwe nibikorwa byinshi. Kuva mubikoresho byubwubatsi kugeza kubiribwa, imiti, ibikoresho byo kwita kubantu, amarangi, hamwe nimyenda, ether ya selile igira uruhare mubicuruzwa byiza, imikorere, kandi birambye. Hamwe nubushakashatsi bukomeje gukorwa no guhanga udushya, akamaro k’inganda za selulose ethers biteganijwe ko kazakomeza kwiyongera, gutera imbere mubikoresho bya siyansi, ibikorwa byinganda, niterambere rirambye.
