Kuvanga hydroxyethyl selulose (HEC) nakazi gasaba kugenzura neza no kumenya neza tekinike. HEC ni ibikoresho bya polymer bifata amazi bikoreshwa cyane mubwubatsi, gutwikira, imiti, imiti ya buri munsi nizindi nganda, hamwe no kubyimba, guhagarikwa, guhuza, emulisation, gukora firime, kurinda colloid nibindi bikorwa.
1. Hitamo uburyo bukwiye bwo gushonga
Ubusanzwe HEC ishonga mumazi akonje, ariko irashobora kandi gushonga mumashanyarazi kama nka Ethanol hamwe nuruvange rwamazi, Ethylene glycol, nibindi. ikoreshwa mubisabwa cyane. Ubwiza bw’amazi bugomba kuba butarimo umwanda, kandi amazi akomeye agomba kwirindwa kugirango yirinde kugira ingaruka kumuti no gukemura.
2. Kugenzura ubushyuhe bwamazi
Ubushyuhe bwamazi bugira uruhare runini mu iseswa rya HEC. Muri rusange, ubushyuhe bwamazi bugomba kubikwa hagati ya 20 ° C na 25 ° C. Niba ubushyuhe bwamazi ari hejuru cyane, HEC iroroshye guhuriza hamwe no gukora misa igoye gushonga; niba ubushyuhe bwamazi buri hasi cyane, igipimo cyo gusesa kizatinda, bigira ingaruka kumikorere. Noneho rero, menya neza ko ubushyuhe bwamazi buri murwego rukwiye mbere yo kuvanga.
3. Guhitamo ibikoresho bivanga
Guhitamo kuvanga ibikoresho biterwa nibisabwa byihariye nibisabwa. Kubikorwa bito cyangwa laboratoire, blender cyangwa intoki zifatishijwe intoki zirashobora gukoreshwa. Kugirango habeho umusaruro munini, kuvanga imisatsi miremire cyangwa gutatanya birasabwa kwemeza kuvanga kimwe no kwirinda gushiraho geli. Umuvuduko ukabije wibikoresho ugomba kuba muke. Kwihuta cyane bizatera umwuka kwinjira mubisubizo kandi bitange ibibyimba; buhoro cyane ntibishobora gukwirakwiza HEC neza.
4. Uburyo bwo kongerera HEC
Mu rwego rwo kwirinda ishingwa rya gel cluster mugihe cyo gusesa HEC, mubisanzwe HEC igomba kongerwaho buhoro buhoro ikurura. Intambwe zihariye nizi zikurikira:
Kubanza kubyutsa: Muburyo bwateguwe bwo gusesa, tangira agitator hanyuma ukangure kumuvuduko wo hagati kugirango ube umuyaga uhamye mumazi.
Buhoro buhoro wongeyeho: Buhoro buhoro kandi binganya kuminjagira ifu ya HEC muri vortex, irinde kongeramo byinshi icyarimwe kugirango wirinde agglomeration. Niba bishoboka, koresha icyuma cyangwa umuyoboro kugirango ugenzure umuvuduko wongeyeho.
Gukomeza kubyutsa: HEC imaze kongerwaho byuzuye, komeza ukangure mugihe runaka, mubisanzwe iminota 30 kugeza kumasaha 1, kugeza igisubizo kiboneye rwose kandi ntagace kacitse.
5. Kugenzura igihe cyo gusesa
Igihe cyo guseswa biterwa nicyiciro cya viscosity cya HEC, ubushyuhe bwikigereranyo gishonga hamwe nuburyo bukurura. HEC ifite urwego rwo hejuru rwinshi rusaba igihe kinini cyo gusesa. Mubisanzwe, bisaba amasaha 1 kugeza kuri 2 kugirango HEC iseswe burundu. Niba ibikoresho byogosha bikoreshwa cyane, igihe cyo gusesa kirashobora kugabanywa, ariko hagomba kwirindwa gukabya gukabije kugirango wirinde kwangirika kwimiterere ya molekile ya HEC.
6. Ongeraho ibindi bikoresho
Mugihe cyo gusesa HEC, ibindi bikoresho birashobora gukenera kongerwaho, nkibibuza, imiti ya pH cyangwa ibindi byongeweho bikora. Ibi bikoresho bigomba kongerwaho buhoro buhoro nyuma yuko HEC isheshwe burundu, kandi gukangura bigomba gukomeza kugirango isaranganya rimwe.
7. Kubika igisubizo
Nyuma yo kuvanga, igisubizo cya HEC kigomba kubikwa mu kintu gifunze kugirango wirinde guhumeka amazi na mikorobe. Ibidukikije bigomba guhorana isuku, byumye kandi bitarenze izuba. Agaciro pH k'igisubizo kagomba guhindurwa murwego rukwiye (mubisanzwe 6-8) kugirango wongere igihe cyo kubika.
8. Kugenzura ubuziranenge
Nyuma yo kuvanga, birasabwa gukora igenzura ryiza kubisubizo, cyane cyane ibipimo ngenderwaho nko kwijimisha, gukorera mu mucyo na pH agaciro k'igisubizo kugirango harebwe niba byujuje ibyateganijwe. Nibiba ngombwa, mikorobe irashobora kandi gukorwa kugirango isuku yumuti ibe.
Hydroxyethyl selile irashobora kuvangwa neza kugirango ibone ibisubizo byiza bya HEC kugirango ihuze ibikenewe ahantu hatandukanye. Mugihe cyibikorwa, buri murongo uragenzurwa cyane kugirango wirinde gukoreshwa nabi no kwemeza kuvanga neza hamwe nubwiza bwibicuruzwa byanyuma.
