Selirulose ya Methyl Hydroxyethyl (MHEC)ni eteri ya cellulose ikoreshwa cyane ikoreshwa cyane mu bukorikori. Igaragaza ubushobozi bwiza bwo gukurura, kubika amazi, gukora filime, gufatanya no gukwirakwiza, bigatuma iba inyongeramusaruro y'ingenzi mu byuma byumye bivanze, kole z'amatafari, ifu ya putty, ibikoresho bishingiye kuri gypsum, na sisitemu zo gusiga.
1. Kugenzura ububyimbirwe n'imitsi y'amaraso
Mu bintu bikozwe muri sima na gypsum, MHEC irushaho gukomera ikora imigozi ya hydrogen hamwe na molekile z'amazi, bikongera ubukana bw'umuti. Iyi miterere irushaho kunoza uburyo amazi atemba n'imikorere y'umuti, ikarinda gutandukana cyangwa kuva amaraso mu gihe cyo kuvanga no gukoresha. Mu matiles ateye ku matafari n'ifu ya putty, kongeramo MHEC bituma ibikoresho byoroha gushyiramo, bigatuma ubuso bungana, kandi bikanoza imikorere myiza y'ubwubatsi.
2. Kubika amazi no gutinda kumisha
Imwe mu miterere igaragara ya MHEC ni uburyo ifata amazi neza. Mu gihe cyo kubaka sima na gypsum, amazi ahinduka mu buryo bwihuse bishobora gutuma adakomera neza, adacika cyangwa ngo agire imiterere ihagije. MHEC ikora filime imwe ya molekile muri sisitemu, igatuma amazi agabanuka kandi igakomeza gushonga neza, bityo sima igakomera neza, bityo igakomeza gukomera no kuramba kwayo. Iyi miterere ni ingenzi cyane mu nyubako zishyushye kandi zumye.
3. Gukoresha neza imikorere
MHEC irushaho kunoza cyane ubushobozi bw'imiti yo mu bwubatsi. Yongera ubushobozi bwo gusya ibintu bya sima, bigatuma byoroha mu gihe cyo gusya no gukurura, ikagabanya imbaraga zo gukora no gukoresha cyane. Byongeye kandi, bitewe n'ubushobozi bwayo bwa thixotropic, MHEC igumana ubukana bwinshi iyo idahinduka mu gihe cyo kubaka, ikarinda kugwa cyangwa kugwa. Iyo ishyizwe mu bikorwa n'imbaraga zo hanze, ubukana bwayo buragabanuka, bigafasha mu kuyikoresha no kuyikwirakwiza. Uku kuvugurura imikorere y'imitsi byongera cyane uburambe mu bwubatsi.
4. Ingufu zongerewe mu mibanire
Mu matiles afatanye, sisitemu zo gukingira inkuta zo hanze, na mortiers zigenga, MHEC irushaho kubika amazi no gutose muri mortiers, yongera uburyo bwo gufatana kwayo ku gice cyo hasi no ku gice cyo hejuru. Kongera MHEC muri tile afatanye bituma amatiles afunguka neza mu gihe cyo kuyashyiraho, birinda ko amazi agwa cyangwa akagwa bitewe n'amazi atakaza vuba. Byongeye kandi, uburyo amazi akoreshwa muri mortiers butuma inyubako ikomera cyane, bigatuma inyubako ikomeza kuba nziza kandi ikagira umutekano.
5. Kunoza imiterere y'ikirere n'ubwiza bw'ubuso
MHEC ifasha mu gukora imiterere y’ubuso bumwe kandi bunini mu buryo bwa mortier na irangi, bigabanya neza amahirwe yo kwangirika. Mu ifu ya putty n’imyambaro yo hanze y’inkuta, MHEC yongera ubushobozi bwo gukora filime no koroshya, bigatuma ubuso bw’inkuta burushaho kuba bwiza kandi butoshye kandi butanga urufatiro rwiza rwo gusigamo imyenda nyuma yaho. Byongeye kandi, irushaho kunoza ubushobozi bwo kudakonja no kudashira kw’ikirere, bigatuma imikorere ihamye mu bihe bitandukanye.
6. Ingero z'Ishyirwa mu Bikorwa
Udukoresho two gufatanya amatafari n'udupira: MHEC igenzura ko amatafari agumana amazi kandi agatuma adakora neza, ikongera igihe cyo gukora no kunoza imbaraga z'imigozi.
Ifu ya Putty n'ibikoresho byo kugereka ku rukuta: MHEC yongera uburyohe n'amazi agumana mu gihe cyo gukurura, ikarinda ingwa no gusenyuka. Ibikoresho bishingiye kuri Gypsum: Nka plaster ya gypsum yigenga na plaster ya gypsum: MHEC yongera ubushobozi bwo gukora no gukomera, ikarinda gutakaza amazi vuba.
Utwuma two gukingira inkuta two hanze: Bituma utwuma twongera ubushobozi bwo gukora, amazi akabikwa, kandi bigatuma utwuma dukomera.
Uruvange rw'imvange: Rukoreshwa cyane mu gusana imvange, imvange ya sima, no gusana imvange, bigatuma imvange ikora neza.
Imitako y’ubwubatsi: MHEC ikomeza, igatatanya, kandi igatuza imitako ishingiye ku mazi nka latex, bigatuma ikora neza kandi ikagira ubwiza bwa firime.
7. Kugereranya n'izindi Ether za Cellulose
Mu ikoreshwa ry’imiti mu bwubatsi, MHEC ikunze kugereranywa na HPMC (hydroxypropyl methylcellulose). Nubwo byombi bifite imiterere isa, MHEC itanga ubushobozi bwo gushonga no kugabanya ikiguzi, bigatuma ikoreshwa mu buryo bwihuta. Ku rundi ruhande, HPMC igaragaza ubushobozi bwo kwihanganira ubushyuhe bwinshi no kuramba. Kubwibyo, mu buryo nyabwo, MHEC cyangwa HPMC, cyangwa uruvange rwabyo byombi, akenshi bitoranywa hashingiwe ku bisabwa mu bwubatsi n’iby’ubukungu kugira ngo haboneke umusaruro mwiza.
Nk'inyongeramusaruro y'ingenzi mu bwubatsi,MHEC, hamwe n’imiterere yayo yuzuye yo gukurura, kubika amazi, kunoza imikorere, gufata neza, no kurwanya ikirere, yakoreshejwe cyane mu bikorwa bitandukanye, harimo kole y’amatafari, ifu ya putty, ibicuruzwa bya gypsum, mortiers zo gukingira, n’amabara. Ntabwo ikora neza gusa ku miterere y’ibikoresho by’ubwubatsi ahubwo inanoza imikorere myiza y’ubwubatsi n’ubwiza bw’umushinga wa nyuma. Uko ibikoresho by’ubwubatsi bikomeza gutera imbere bikagera ku bimera bito, bitangiza ibidukikije, kandi bifite imikorere myiza, amahirwe yo gukoresha MHEC azagenda yiyongera, kandi umwanya wayo w’ingenzi mu nganda z’ubutabire mu bwubatsi uzakomeza kwiyongera.
