Methylhydroxyethylcellulose (MHEC) ni ikintu cy'ingenzi mu nganda zitandukanye, cyane cyane mu bwubatsi, imiti, n'ibicuruzwa byita ku muntu. Igikorwa cyacyo cyambere nkibikoresho bigumana amazi bituma biba ingenzi mubikorwa nkibikoresho bya sima, imiti yimiti, hamwe no kwisiga.
1. Imiterere ya molekulari ya MHEC:
MHEC ni iy'umuryango wa selulose ethers, ikomoka kuri selile - polymer isanzwe ibaho iboneka murukuta rw'utugingo ngengabuzima. MHEC ikomatanyirizwa muri etherification ya selile, aho amatsinda ya methyl na hydroxyethyl yinjizwa mumugongo wa selile. Urwego rwo gusimbuza (DS) rwaya matsinda ruratandukanye, bigira ingaruka kumiterere ya MHEC nko gukemuka, kwiyegeranya, hamwe nubushobozi bwo gufata amazi.
2. Gukemura no gutatanya:
MHEC yerekana imbaraga nziza mumazi bitewe nuko hydrophilique hydroxyethyl ihari. Iyo ikwirakwijwe mu mazi, molekile ya MHEC ihura n’amazi, hamwe na molekile y’amazi ikora hydrogène ihuza amatsinda ya hydroxyl igaragara ku mugongo wa selile. Ubu buryo bwo kuvoma butera kubyimba ibice bya MHEC no gushiraho igisubizo kiboneye cyangwa gutatana.
3. Uburyo bwo gufata amazi:
Uburyo bwo gufata amazi ya MHEC ni impande nyinshi kandi zirimo ibintu byinshi:
a. Guhuza Hydrogen: molekile ya MHEC ifite amatsinda menshi ya hydroxyl ashoboye gukora imigozi ya hydrogène hamwe na molekile zamazi. Iyi mikoranire yongerera amazi gufata imitego muri materix ya polymer binyuze muri hydrogen.
b. Ubushobozi bwo kubyimba: Kuba hari amatsinda ya hydrophilique na hydrophobique muri MHEC bituma ashobora kubyimba cyane iyo ahuye namazi. Mugihe molekile zamazi zinjiye mumurongo wa polymer, iminyururu ya MHEC irabyimba, ikora imiterere isa na gel igumana amazi muri matrise yayo.
c. Igikorwa cya Capillary: Mubikorwa byubwubatsi, MHEC ikunze kongerwaho ibikoresho bya sima nka minisiteri cyangwa beto kugirango bitezimbere imikorere kandi bigabanye gutakaza amazi. MHEC ikora mu myobo ya capillary yibi bikoresho, ikumira amazi yihuta kandi ikagumana ubushuhe bumwe. Iki gikorwa cya capillary cyongera neza hydrated no gukiza inzira, biganisha ku kunoza imbaraga nigihe kirekire cyibicuruzwa byanyuma.
d. Ibyiza byo gukora firime: Usibye ubushobozi bwayo bwo kubika amazi mubisubizo byinshi, MHEC irashobora kandi gukora firime yoroheje mugihe ikoreshejwe hejuru. Izi firime zikora nkinzitizi, zigabanya gutakaza amazi binyuze mu guhumeka no gutanga uburinzi bwimihindagurikire y’amazi.
4. Ingaruka z'impamyabumenyi yo gusimburwa (DS):
Urwego rwo gusimbuza methyl na hydroxyethyl kumatsinda ya selulose umugongo bigira ingaruka zikomeye kumiterere yo gufata amazi ya MHEC. Indangagaciro za DS zo hejuru muri rusange zitera imbaraga nyinshi zo gufata amazi kubera kwiyongera kwa hydrophilique no guhuza urunigi. Nyamara, DS irenze urugero indangagaciro zishobora kuganisha ku gukabya gukabije cyangwa kwishongora, bigira ingaruka kumikorere no mumikorere ya MHEC mubikorwa bitandukanye.
5. Imikoranire nibindi bice:
Mubikorwa bigoye nka farumasi cyangwa ibicuruzwa byita kumuntu, MHEC ikorana nibindi bikoresho, harimo ibikorana imbaraga, surfactants, hamwe nubunini. Iyi mikoranire irashobora kugira ingaruka muri rusange, gukomera, no gukora neza. Kurugero, muguhagarika imiti, MHEC irashobora gufasha guhagarika ibintu bikora neza mugice cyamazi, ikumira imyanda cyangwa guteranya.
6. Ibidukikije:
Mugihe MHEC idashobora kwangirika kandi mubisanzwe ifatwa nkibidukikije, umusaruro wacyo urashobora kuba urimo imiti itanga imyanda cyangwa nibindi bicuruzwa. Ababikora baragenda bashakisha uburyo burambye bwo kubyaza umusaruro no gushakisha selile ikomoka kuri biomass ishobora kuvugururwa kugirango bagabanye ingaruka z’ibidukikije.
7. Umwanzuro:
Methylhydroxyethylcellulose (MHEC) ni uburyo butandukanye bwo kubika amazi hamwe nibikorwa bitandukanye mubikorwa bitandukanye. Imiterere ya molekile yayo, gukomera, hamwe n’imikoranire n’amazi bituma igumana neza ubushuhe, kunoza imikorere, no kuzamura imikorere yimikorere. Gusobanukirwa imikorere yimikorere ya MHEC ningirakamaro mugutezimbere imikoreshereze yayo mubikorwa bitandukanye mugihe urebye ibintu nkurwego rwo gusimbuza, guhuza nibindi bikoresho, hamwe nibidukikije.
