Ether ya selulose ni polymers zitandukanye kandi zinyuranye zikoreshwa mubikorwa bitandukanye, harimo no gukora ibumba ryubuki nibindi bicuruzwa.
1. Intangiriro kuri selile ether:
Ether ya selile ni inkomoko ya selile, polymer karemano iboneka murukuta rwibimera.Iraboneka muguhindura imiti ya selile, bikavamo gushonga amazi cyangwa polymers ikwirakwiza amazi.Inkomoko rusange ya selile irimo ibiti, ipamba, nibindi bikoresho byibimera.
2. Ubwoko bwa selile ya selile:
Hariho ubwoko bwinshi bwa selile ethers, buri kimwe gifite imitungo yihariye ikwiranye na progaramu yihariye.Ubwoko bumwe busanzwe burimo methylcellulose (MC), Ethylcellulose (EC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), na carboxymethylcellulose (CMC).Guhitamo selulose ether biterwa nibintu byifuzwa byibicuruzwa byanyuma.
3. Uburyo bwo gukora:
Umusaruro wa selile ya selile urimo intambwe nyinshi, harimo gukuramo selile, guhindura imiti, no kweza.Cellulose yabanje gukurwa mubihingwa hanyuma imiti ikoreshwa mugutangiza amatsinda akora nka methyl, ethyl, hydroxyethyl cyangwa carboxymethyl.Ether ya selile ivamo noneho isukurwa kugirango ikureho umwanda kandi igere kubwiza bwifuzwa.
4. Ibyiza bya selile ether:
Ethers ya selulose ifite ibintu bitandukanye byifuzwa, bigatuma ikoreshwa muburyo butandukanye bwa porogaramu.Iyi miterere irimo gushiramo amazi, ubushobozi bwo gukora firime, ubushobozi bwo kubyimba, no gutuza hejuru yubushyuhe bwagutse na pH.Iyi mitungo igira uruhare muburyo butandukanye bwa selile ya selile mu nganda zitandukanye.
5. Gukoresha selile ether:
Ether ya selile ikoreshwa mu nganda nyinshi, harimo imiti, ibiryo, ubwubatsi, imyenda n’ububumbyi.Porogaramu zayo ziratangira gukoreshwa nkibikoresho byiyongera mubiribwa kugeza kuzamura imitungo yibikoresho.Mu rwego rw’ubutaka, ethers ya selile igira uruhare runini mukubyara ubuki bwubuki.
6. Cellulose ether mubutaka bwubuki:
Ubuki bwubuki nibikoresho byubaka hamwe na selile zitondekanye muburyo bwa mpande esheshatu cyangwa ubuki.Ubukorikori buzwiho ubuso burebure, kwaguka kwinshi kwubushyuhe, hamwe nubushyuhe buhebuje hamwe nubwinshi bwimurwa.Ether ya selile ikoreshwa mugukora ubukerarugendo bwubuki kubera impamvu zikurikira:
Guhindura hamwe na Rheologiya Guhindura: Ethers ya selile ikora nka binders, ifata uduce duto twa ceramic hamwe mugihe cyo kubumba.Byongeye kandi, ikora nka moderi ihindura imvugo, igira ingaruka kumyuka no guhindura ibintu bya ceramic.
Imiterere yumubiri wicyatsi: Ceramic slurries irimo selile ya selile ikoreshwa mugukora umubiri wicyatsi kubutaka bwubuki.Imibiri yicyatsi nuburyo butemewe bwubutaka bwakozwe kandi bwumutse mbere yo gutunganywa.
Guhuriza hamwe no gukama: Ethers ya selile ifasha uduce twa ceramic gukomera mugihe cyo kumisha.Irinda gucika no guhindura ibintu, kwemeza umubiri wicyatsi kugumana ubusugire bwimiterere.
Gutwika no gucumura: Mubyiciro byakurikiyeho kubyara ubuki bwibumba ceramic, ethers ya selile irashya, hasigara icyuho gifasha gukora imiterere yubuki.Inzira yo gucumura noneho ikomeza kubona ibicuruzwa byanyuma bya ceramic.
7. Ubundi buryo bukoreshwa na selile ya selile:
Usibye ubukerarugendo bwubuki, ethers ya selile ikoreshwa mubindi bicuruzwa bitandukanye ninganda:
Imiti ya farumasi: Ikoreshwa nka binder kandi idahwitse muburyo bwa tablet.
Inganda zibiribwa: Ethers ya selile ikoreshwa nkibibyimbye, stabilisateur na emulisiferi mubiryo.
Ibikoresho byubwubatsi: Itezimbere imiterere ya minisiteri, ibifatika hamwe na coatings.
Imyenda: Ethers ya Cellulose ikoreshwa mugucapa imyenda no gupima porogaramu.
8. Ibibazo n'ibitekerezo:
Mugihe selile ya selile itanga ibyiza byinshi, imikoreshereze yabo nayo itanga ibibazo bimwe.Ibi birashobora kubamo ibibazo by ibidukikije bijyanye nibikorwa byumusaruro no gukenera isoko yibikoresho birambye.Ibikorwa byubushakashatsi niterambere birakomeje kugirango bikemure ibyo bibazo kandi bitezimbere muri rusange ibicuruzwa bya selile.
9. Ibizaza hamwe niterambere:
Mugihe ikoranabuhanga ritera imbere kandi rirambye rikaba ikibazo cyingenzi, ejo hazaza ha ethers ya selile irashobora kuba irimo udushya mubikorwa byo gukora, kongera ikoreshwa ryibikoresho bishingiye kuri bio, no guteza imbere ibikorwa bishya.Ubwinshi bwa selile ethers ituma iba ibikoresho bitanga inganda zitandukanye, kandi ubushakashatsi burimo burashobora kwerekana uburyo bushya.
10. Umwanzuro:
Cellulose ethers ni polymers zitandukanye hamwe nibikorwa byinshi mubikorwa byinshi.Imikoreshereze yacyo muri selile yububiko bugaragaza akamaro kayo muguhindura ibikoresho bigezweho bifite imiterere yihariye.Mugihe inganda zikomeje gushakisha ibikoresho birambye kandi bikora, selile ya selile iteganijwe kugira uruhare runini mugukemura ibyo bikenewe.Ubushakashatsi niterambere bikomeje bizakomeza kwagura ibikorwa bya selile ether kandi bizamura iterambere ryabo muri rusange.
