Hydroxyethyl Methyl Cellulose (HEMC)ni ikintu cy'ingenzi cya eteri ya selulosi kandi kiri mu gice cya eteri ya selulosi itari ioni. HEMC iboneka binyuze mu guhindura imiti hamwe na selulosi karemano nk'ibikoresho fatizo. Imiterere yayo irimo hydroxyethyl na methyl substituents, bityo ikaba ifite imiterere yihariye y'umubiri n'imiti kandi ikoreshwa cyane mu bikoresho by'ubwubatsi, gusiga irangi, imiti ya buri munsi, ubuvuzi n'ibindi bikorwa.
1. Imiterere y'umubiri n'iya shimi
Ubusanzwe HEMC ni ifu cyangwa uduce tw’umweru cyangwa tudafite umweru, byoroshye gushonga mu mazi akonje kugira ngo bikore umuti wa colloidal ubonerana cyangwa ufite umwuka wa colloidal. Ibiranga by'ingenzi birimo:
Gushonga: HEMC ishobora gushonga vuba mu mazi akonje, ariko ishonga nabi mu mazi ashyushye. Gushonga kwayo no gushonga kwayo birahinduka bitewe n'impinduka mu bushyuhe n'agaciro ka pH.
Ingaruka zo gushonga: HEMC ifite ubushobozi bukomeye bwo gushonga mu mazi kandi ishobora kongera ubukana bw'umuti.
Kubika amazi: Ifite ubushobozi bwiza bwo kubika amazi kandi ishobora gukumira ibura ry'amazi mu bikoresho.
Imiterere yo gukora filime: HEMC ishobora gukora filime ibonerana ku buso ifite imbaraga n'ubukana runaka.
Ubushyuhe: Bitewe n'imiterere yayo yihariye ya molekile, HEMC ishobora gutanga ubushyuhe bwiza cyane.
2. Uburyo bwo gukora
Uburyo bwo gukora HEMC bukubiyemo ahanini intambwe zikurikira:
Alkalization: Selulosi karemano ivurwa mu gihe cy'ubukana bwa alkali kugira ngo ikore selulosi ya alkali.
Uburyo bwo gupima imiterere y'ibintu biva mu bintu bihindura imiterere y'ibintu: Iyo wongeyeho uburyo bwo gupima imiterere y'ibintu biva mu bintu bihindura imiterere y'ibintu (nk'imiti ya methyl kloride) n'uburyo bwo gupima imiterere y'ibintu biva mu bintu bihindura imiterere y'ibintu (nk'imiti ya ethylene oxide), cellulose ihinduka uburyo bwo gupima imiterere y'ibintu biva mu bintu bihindura imiterere y'ibintu ku bushyuhe n'umuvuduko runaka.
Nyuma yo kuvurwa: Umusaruro w'ibikomoka ku bimera uvamo urakurwamo, wozwa, wumishwa, hanyuma ugasenywa kugira ngo amaherezo uboneHEMCibicuruzwa.
3. Ahantu hakuru hakoreshwa
(1) Ibikoresho by'ubwubatsi HEMC ikoreshwa cyane mu bwubatsi, cyane cyane mu byuma bya sima, ifu ya putty, kole y'amatafari, gypsum n'ibindi bicuruzwa. Ishobora kunoza ubukana, kubika amazi no kwirinda kugwa kw'ibikoresho by'ubwubatsi, kongera igihe cyo gufungura, bityo ikanoza imikorere y'ubwubatsi.
(2) Amarangi n'iwino Mu marangi, HEMC ikora nk'ikintu gikomeza ubukonje n'ubudahangarwa kugira ngo yongere ubukana n'imiterere y'irangi no gukumira ko irangi rigwa. Byongeye kandi, ishobora gutanga imiterere myiza yo gukora firime, bigatuma ubuso bw'irangi burushaho kuba bumwe kandi bunoze.
(3) Imiti n'amavuta yo kwisiga HEMC ishobora gukoreshwa nk'umuti ufata neza kandi ugakora filime mu binini bya farumasi, ndetse no mu gukurura no koroshya uruhu. Bitewe n'umutekano wayo mwinshi no kuba ikora neza, ikunze gukoreshwa mu bicuruzwa nka ibitonyanga by'amaso, imiti isukura mu maso, n'amavuta yo kwisiga.
(4) Imiti ikoreshwa buri munsi Mu miti ikoreshwa buri munsi nk'isabune n'amavuta yo koza amenyo, HEMC ikoreshwa nk'umuti ukomeza ubushyuhe n'ubudahangarwa kugira ngo yongere imiterere y'umubiri n'ubudahangarwa bw'umuti.
4. Ibyiza no kurengera ibidukikije
HEMC ifite ubushobozi bwo kwangirika cyane no kurengera ibidukikije kandi ntabwo izatera umwanda mu gihe kirekire ku bidukikije. Ariko kandi, ntabwo ari uburozi kandi nta ngaruka mbi ifite, ntitera uruhu rw'umuntu n'ururenda rw'imitsi, kandi yujuje ibisabwa mu kurengera ibidukikije n'iterambere rirambye.
5. Ibyiza by'isoko n'iterambere ryaryo
Bitewe n’iterambere ry’inganda z’ubwubatsi n’inganda zikora imiti ya buri munsi, isoko rya HEMC rikomeje kwiyongera. Mu gihe kizaza, uko abantu barushaho kwita ku bikoresho bibungabunga ibidukikije no kunoza imikorere y’ibicuruzwa, HEMC izakoreshwa cyane mu nzego zitandukanye. Byongeye kandi, ubushakashatsi n’iterambere ry’ibicuruzwa bishya bikora neza bya HEMC (nk’ibidashyuha cyane n’ibidashyuha vuba) nabyo bizateza imbere ikoreshwa ryabyo ku isoko ryo ku rwego rwo hejuru.
Nk'umusemburo wa cellulose ukoresha imikorere myinshi kandi ukora neza,hydroxyethyl methylcellulose (HEMC)Ifite uruhare runini mu bwubatsi, gusiga irangi, ubuvuzi n'izindi nzego hamwe n'imiterere yayo yihariye y'umubiri n'imiti. Hamwe n'iterambere rya siyansi n'ikoranabuhanga no kwaguka kw'amashami akoreshwa, HEMC izagira uruhare runini mu nganda zigezweho kandi itange inkunga ikomeye mu iterambere ry'inganda zifitanye isano.
