Methyl Hydroxyethyl Cellulose (MHEC) yashongeshejwe mu gikoresho gitose

Selirulose ya Methyl Hydroxyethyl (MHEC)ni eteri ya cellulose idafite ionic ikoreshwa cyane mu bikoresho by'ubwubatsi, cyane cyane mu gikoresho cy'amazi, kandi igira uruhare runini. Gushonga kw'amazi n'imiterere ya molekile nyinshi bituma ikora umuti utose mu mazi, bigatuma igikoresho cy'amazi kiba cyiza cyane, bigatuma amazi agumana neza kandi kikagira ubushobozi bwo kwihutisha imirimo yo kucyubaka.

1. Imiterere y'ibanze ya MHEC

MHEC ni eteri ikomoka kuri selulosi ikorwa binyuze mu kwinjiza amatsinda ya methyl na hydroxyethyl muri selulosi karemano binyuze mu gukora etherification. Ifite ubushobozi bwo gushonga neza mu mazi, ubushobozi bwo gukora filime, kubika amazi no gufatana. Irahamye mu bihe biri hagati y’imiterere ya aside na alkaline kandi ifite ubushobozi bwo guhuza neza n’ibidukikije kandi ifite umutekano mu bidukikije.

MHEC ishongeshwa mu mazi akonje ku bushyuhe bw'icyumba kugira ngo ikore umuti wa colloidal ubonerana cyangwa unyuranamo, kandi ntishongeshwa mu mazi ashyushye cyangwa mu bintu byinshi bishongeshwa mu buryo bw'umwimerere. Uburyo bwo kuyishongesha ni uburyo bwo kwaguka no gukwirakwiza no kuyishongesha, kandi ntabwo ikubiyemo imikorere ya shimi.

2. Uburyo bwo gushonga kwa MHEC mu gikoresho gitose

Mu gikoresho cy’amazi, MHEC ikunze gushyirwa mu mvange yumye mu buryo bw’ifu, hanyuma ikagenda ishonga buhoro buhoro mu gihe cyo kongeramo amazi no kuvanga:

Intambwe ya mbere - kwinjiza amazi no kubyimba: Uduce twa MHEC twuma amazi hanyuma tukabyimba hejuru nyuma yo kugera ku mazi, bigatuma habaho irangi rya gel.

Icyiciro cyo hagati - gukwirakwira no kubyimba: Iyo ukoresheje uburyo bwo gukurura, igice cy'imiterere ya kolloidal kirasenyuka, maze MHEC itangira gukwirakwira mu buryo bwose.

Icyiciro cya nyuma – gusenyuka burundu: Nyuma yo kuvanga kenshi n'igihe runaka, MHEC irashonga burundu kugira ngo ikore umuti wa polymer uhamye, ugakwirakwizwa mu buryo bungana muri mortier.

Mu bikorwa bifatika, igipimo cyo gusenyuka kwa MHEC kizaterwa n'ubukana bwo gukangura, ubushyuhe bw'amazi, ingano y'uduce, n'ibindi bikoresho biri muri formula (nka sima, gypsum, umucanga, nibindi). Gugenzura neza ibi bipimo bishobora kwirinda ikibazo cyo kwivanga cyangwa gusenyuka ku buryo budahagije.

3. Ibikorwa byingenzi bya MHEC muri minisiteri itose

3.1. Kongera ubushobozi bwo kubika amazi

Ingaruka zikomeye za MHEC ni ukunoza cyane ubushobozi bwo kubika amazi muri sima, kugabanya imyuka y’amazi yihuta, kongera igihe cyo kunywa sima, bityo bikanongera imbaraga n’imbaraga byo gufatana, no gukumira gucika vuba.

3.2. Kunoza imikorere y'ubwubatsi

Bitewe n'uburyo MHEC ikoresha amavuta menshi kandi ikagira ubugari, sima ifite ubushobozi bwo gukora neza, ikoroha kandi ikwirakwira neza, bigabanya ingorane zo kubaka no kunoza imikorere. Cyane cyane mu gihe cyo gusigwa no gusigwa amatafari, ishobora kubuza sima kugwa no kunyerera.

3.3. Kunoza imikorere y'imibanire

Imiterere y'urusobe rw'imiyoboro ya colloidal ikorwa na MHEC muri mortilator yongera imbaraga zo guhuza hagati ya mortilator n'urwego rw'ibanze, cyane cyane iyo yubakwa ku buso buhagaze cyangwa hejuru, bigatuma mortilator idagwa kandi ikongera icyizere cyo kubaka.

3.4. Hindura imiterere n'uburyo ibintu bigenda neza

Mu guhindura ingano ya MHEC, imiterere n'imikorere ya rheological ya mortical itose bishobora kugenzurwa, kugira ngo igire fluid ikwiye, yoroheye kubaka, kandi ntigire ingaruka ku ngaruka zo gushushanya bitewe n'amazi menshi atemba.

3.5. Kunoza imikorere yo kurwanya kunyerera

Mu bikorwa nka kole z'amatafari n'uduti two guhuza, MHEC ishobora kubuza neza kole z'amatafari kunyerera, kunoza uburyo inyubako zihagaze neza, no kubahiriza ibisabwa mu bwubatsi byo gupakira uburebure n'ubunini bw'amatafari.

4. Ingaruka z'igipimo cya MHEC ku mikorere ya mortilage

Ingano y’inyongera ya MHEC isanzwe igenzurwa hagati ya 0.1% na 0.5% (hashingiwe ku giteranyo cy’ibikoresho byumye). Ingaruka z’ibipimo bitandukanye ku mikorere ya mortiweri ni izi zikurikira:

Igipimo gito (<0.1%): amazi agumana yarushijeho kuba meza, ariko iterambere mu mikorere y'inyubako ntirigaragara.

Igipimo kiringaniye (0.2% ~ 0.4%): Imikorere myiza cyane, iterambere riringaniye ry’amazi abikwa, imikorere y’inyubako, n’imbaraga zo gufatanya.

Gukoresha cyane (> 0.5%): Bishobora gutuma sima ikomera cyane, bigabanura amazi, kandi bikongera igihe cyo kuyishyiraho.

Bityo rero, mu itegurwa ry’ifishi yihariye, ni ngombwa kumenya ingano nziza y’inyongera ya MHEC binyuze mu igerageza kugira ngo haboneke ingaruka nziza zo kuyikoresha.

5. Guhuza n'izindi nyongeramusaruro

MHEC ishobora gukoreshwa hamwe n'ibindi bintu bitandukanye by'ingenzi, nka:

Hamwe n'ifu ya latex ishobora gusubirwamo (VAE): bifasha hamwe kongera ubworoherane n'imbaraga zo gufatanya kwa morti;

Ku bijyanye n'ibikoresho bigabanya ubushyuhe: gutinza amazi ya sima, gukorana na MHEC kugira ngo inoze idirishya ry'ubwubatsi;

Hamwe n'ibirungo byuzuza/ibirungo by'amabuye y'agaciro: guhuza uburyo amazi ahinduka n'iterambere ry'imbaraga, gushimangira imiterere ya morti.

Nk'inyongeramusaruro y'ingenzi mu gikoresho cy'amazi,hydroxyethyl methylcellulose (MHEC) igira uruhare runini mu gutuma ibintu bikomera, kubika amazi, kunoza no kunoza ubwubatsi mu buryo bwa mortiweri binyuze mu miterere yayo myiza yo gushonga mu mazi. Ni inyongeramusaruro ikomeye mu bikoresho by'ubwubatsi bigezweho. Binyuze mu guhitamo ingero n'ingano bya siyansi, MHEC ishobora kunoza imikorere ya mortiweri, ihuze n'ibikenewe mu bwubatsi butandukanye, kandi igafasha kubaka mu buryo buzira uburyarya kandi bunoze.
