Hydroxye ether (HEC) ni amazi adafite amazi -imisemburo ya polymer ikomoka kuri selile.Ubusanzwe ikoreshwa mu nganda zitandukanye, nk'imiti, amavuta yo kwisiga n'ibiryo, nk'ibyimbye hamwe na gel.Gukemura HEC ni inzira itaziguye, ariko igomba gusuzuma ibintu nkubushyuhe, pH no gukurura.
Umwirondoro wa Hec:
Hydroxye Ethyl selulose (HEC) ni selile ikomoka kuri selile ikomatanyirizwa hamwe na reaction ya oxyde.Igisubizo cyinjiza hydroxyl mumurongo wingenzi wa selile, bityo igaha polymer mumazi -gushonga.HEC irangwa nubushobozi bwo gukora gele ibonerana kandi ihamye mugisubizo cyamazi, bigatuma iba ibintu byinshi mubikorwa byinshi.
Ibintu bigira ingaruka ku iseswa rya HEC:
1. Ubushyuhe:
Ubushyuhe bwa HEC.Ubushyuhe bwo hejuru mubusanzwe butera gushonga vuba.
Amazi ashyushye ubusanzwe akoreshwa mugutezimbere inzira yo gukemura.Nyamara, ubushyuhe bukabije bugomba kwirindwa kugirango birinde kwangirika.
2. Urwego rwa PH:
HEC ihagaze neza mugari ya pH mugari, mubisanzwe hagati ya 2 na 12. Guhindura pH agaciro k'igisubizo bishobora kugira ingaruka kumuvuduko.
Iseswa ryiza mubisanzwe ni ihitamo ryambere kuba alkaline nkeya ya pH.
3. Kangura:
Kangura cyangwa ukangure kugirango wongere iseswa rya HEC.Ivangavanze ryoroheje rifasha polymer kuringaniza mumashanyarazi kugirango irinde guhagarika.
Gukoresha imashini cyangwa gukoresha imashini ivanga ibintu bisanzwe muri laboratoire.
4. Guhitamo ibisubizo:
HEC ibora mumazi kugirango ibone igisubizo kiboneye.Guhitamo ubwiza bwamazi (distillation, exfoliating) birashobora kugira ingaruka kumeneka.
Kwirinda umwanda mumashanyarazi ni ngombwa kugirango wirinde ingaruka mbi zose.
Uburyo bwo gusesa HEC:
1. Kuramo amazi ashyushye:
Shyushya amazi kubushyuhe burenze ubushyuhe bwicyumba, ariko munsi yubushyuhe bwa HEC.
Guhora ubyutsa HEC buhoro buhoro wongere mumazi kugirango wirinde guhagarara.
Komeza ubushyuhe kugeza bumaze gushonga.
2. Amazi akonje arashonga:
Nubwo itinda kuruta amazi ashyushye, amazi akonje arashobora gushonga neza HEC.
Buhoro buhoro ongeramo HEC mumazi akonje hanyuma uvange imvange.
Gutandukanya no gusesa igihe gihagije kuri polymers.
3. Guhindura PH:
Ukurikije ibisabwa, pH yamazi akoreshwa muguhindura pH yamazi kurwego rusabwa.
Kurikirana impinduka za pH mugihe cyo guseswa kugirango umenye neza.
4. Ikoranabuhanga rishimishije:
Koresha imashini, gukurura magnetiki, cyangwa kuvanga byoroheje ubundi buryo kugirango ufashe HEC gutatana.
Komeza kubyutsa kugeza igisubizo kiboneye.
5. Guhuza uburyo:
Gukomatanya ubushyuhe, pH guhinduranya no gukurura bikoreshwa mugutezimbere.
Ibipimo bitandukanye byubushakashatsi kugirango ugere ku gipimo gikenewe cyo guseswa.
gukemura ibibazo:
1. Guhagarika:
Niba guhagarika bibaye, nyamuneka gabanya ubwiyongere bwumuti kandi wongere imbaraga za HEC.
Intoki zangirika itsinda iryo ariryo ryose ryashizweho, cyangwa uhindure umuvuduko ukurura.
2. Iseswa ridahagije:
Niba polymer idashonga burundu, reba umwanda uri mumashanyarazi cyangwa udahagije.
Tekereza guhindura ubushyuhe cyangwa gukoresha uburyo butandukanye bwo gukemura.
Gukemura HEC bikubiyemo ibintu bitandukanye, birimo ubushyuhe, pH, hamwe no gukurura.Gusobanukirwa ibiranga HEC nibisabwa byihariye bya porogaramu ni ngombwa kugirango iseswa ryiza.Ubushakashatsi bwikigereranyo no gukurikirana neza bizafasha gukemura ibibazo byose bishoboka.Buri gihe ukurikize ubuyobozi bwumutekano kandi ubaze imbonerahamwe yamakuru ya tekiniki kugirango ubone amabwiriza yihariye yatanzwe nuwabikoze.
