Uruhare rw'ingenzi rwa eteri ya selulose mu nyubako zigezweho

Cellulose ether ni ubwoko bw'ibinyabutabire bya polymer biva mu guhindura cellulose karemano, bifite ubushobozi bwo gushonga neza, gukomera, kubika amazi no gukora filime. Ubwoko busanzwe bwa ether ya cellulose burimohydroxypropyl methylcellulose (HPMC), methylcellulose (MC), selulose ya hydroxyethyl (HEC), hydroxyethyl methylcellulose (HEMC), n'ibindi. Bikoreshwa cyane mu bikoresho by'ubwubatsi, cyane cyane mu buryo bw'imyanda yumye.

1. Uburyo bwo gukora kwa eteri ya selulosi muri morti

Mu buryo bwa none bwo gushushanya ibintu bya morti, cellulose ether, nk'inyongeramusaruro y'ingenzi mu binyabutabire, igira uruhare runini muri ibi bikurikira:

1.1. Kurushaho kubika amazi neza

Molekile za eteri za selulosi zikungahaye ku matsinda akunda amazi, ashobora guhumeka no gufunga amazi, gutinda guhumeka no kwinjira mu mazi, bigatuma amazi agira uruhare rusesuye mu gukora sima, no kunoza imikorere myiza yo gushingwa imbaraga hakiri kare. Iyo yubakishije ku bintu bifite amazi menshi (nk'ubukonje buvamo umwuka, amatafari), eteri ya selulosi ishobora gukumira amazi menshi kandi ikirinda gucikamo ibice no kuyasya.

1.2. Gukomera no kunoza imikorere y'inyubako

Cellulose ether ishobora kongera cyane ubukana n'ubushyuhe bya mortiropi, ku buryo mortiro igaragaza ubushyuhe bwiza n'imikorere myiza mu bwubatsi iyo ivanze kandi ikoreshwa, ariko ifite ubushobozi bwo gufatana no kudaserera mu gihe idahinduka, bityo ikarushaho kunoza uburyo inyubako ikora kandi ikagabanya kugwa.

1.3. Kunoza imbaraga zo guhuza

Mu kongera uburyo urusenda ruhurirana n’imikorere y’urusenda ruhurirana n’urusenda, eteri ya cellulose yongera imbaraga zo guhuza urusenda, birinda ibibazo nko gutandukanya no gupfuka mu gice cya nyuma, kandi ikwiriye cyane cyane kole z’amatafari, urusenda rwo kwihuza n’urusenda rwo hanze.

1.4. Gutinda gushyiraho igihe no kunoza imikorere

Cellulose ether ishobora kongera igihe cyo gufungura cy’imashini, bigatuma abakozi bagira umwanya uhagije wo kuyikosora no kuyikata mu gihe cyo kuyibaka, mu gihe birinda inenge ziterwa no kuma imburagihe.

2. Gukoresha eteri ya selulose mu bwoko butandukanye bwa mortiers

2.1. Gusiga sima

Kongeramo ether ya cellulose muri mortier yo gusigwa bishobora kunoza uburyo mortier n'urukuta bifatanye, kandi bikarinda ibibazo nko "gupfuka no kwangirika". Amazi meza ashobora kandi gutuma urwego rw'ivu rwuma neza kandi bikanoza imikorere yarwo.

2.2. Gufata amatafari

Kole zo mu mabati zifite ibisabwa cyane kugira ngo amazi akomeze kubikwa no kudacika intege. Cellulose ether ishobora kongera imbaraga zayo zo gufatana, ikarinda amabati kugwa hasi, kandi ikagaragaza ingaruka nziza zo gufatana inyuma y’amabati kandi amazi akaba make.

2.3. Sima yo kwiyongerera ubushobozi

Cellulose ether itanga uburyo bukwiye bwo kubika amazi mu gikoresho cyigenga kugira ngo gikoreshwe neza nta bibazo by’ubwiza nko kuva amaraso no kwangirika. Ubwoko bwa cellulose ether bufite umuvuduko muke ni bwo bukwiriye cyane muri ubwo buryo.

2.4. Sima y'ubushyuhe (Sisitemu ya EIFS)

Muri sisitemu yo gukingira inkuta zo hanze, eteri ya cellulose yongerwa kuri morti yo guhuza no kurwanya uduce duto kugira ngo yongere ubushobozi bwo guhangana n’uduce duto, yongere imbaraga zo guhuza, kandi yongere kuramba no guhagarara kw’urusobe rw’ibintu muri rusange.

2.5. Sima y'amabuye yumye ivanze n'umusenyi

Urusenda rw'amabuye rwumye rukunze gukoreshwa mu kubaka amatafari. Cellulose ether ishobora kunoza ubushobozi bwayo bwo gusohora amazi, kubika amazi no kurwanya kugwa, bigatuma urusenda rusa neza kandi rwuzuye, kandi ikongera ubucucike n'imbaraga zo gukanda kw'amabuye.

3. Ibintu bigira ingaruka ku mikorere

Imikorere ya eteri ya selulosi igira ingaruka zikomeye ku mikorere ya nyuma ya mortila, cyane cyane harimo ibi bikurikira:

Ingano y'ubucucike: Eteri ya cellulose ifite ubucucike bwinshi ikwiriye ama-mortar asaba ubushobozi bwinshi bwo kwirinda kunyerera, mu gihe ubucucike buke bukwiriye ibikoresho byigenga.

Ingano yo gusimbuza (DS) n'impinduka z'umuyoboro (MS): Ibi bipimo bibiri bigena uburyo imyuka ishonga, uburyo amazi abikwa n'uburyo imyuka ya selulose ihagaze neza.

Ingano y'uduce: Ifu nziza yoroshye gukwirakwizwa mu gishishwa, bigatuma ibintu byose bihinduka kimwe.

Igipimo cyo gushonga: Eteri ya cellulose ishonga vuba ifasha kunoza imikorere no kuvanga neza.

4. Inama ku ikoreshwa n'uburyo bwo kwirinda

Hitamo ubukana bukwiye n'ubwoko bwa eteri ya selulose kugira ngo bihuze n'ibisabwa mu buryo bwihariye bwa mortier.

Uburyo bwo kuvanga bugomba gutuma eteri ya selulose ikwirakwira neza kugira ngo hirindwe ko ubwiyongere bw'aho hantu bugira ingaruka ku mikorere.

Genzura ingano y'inyongera, muri rusange 0.1%-0.5% by'uburemere bwa sima. Iyo irenze urugero ishobora kugira ingaruka ku bukonje n'igihe cyo kuma.

Iyo ikoreshejwe hamwe n'ibindi birungo (nk'ifu ya latex ishobora gusubirwamo, ikintu gigabanya amazi, nibindi), hakwiye kwitabwaho isuzuma ry'uko bihuye n'ibirungo.

Nk'imwe mu nyongeramusaruro z'ingenzi mu ibumba rigezweho ryumye,eteri ya selulose igira uruhare rudasimburwa mu mikorere y'ubwubatsi, imiterere ya mekanike no kuramba. Bitewe n'iterambere ry'inyubako z'icyatsi kibisi n'inyubako zakozwe mbere, icyifuzo cya sima ikora neza gikomeje kwiyongera, kandi ubwoko n'ikoranabuhanga rya eta ya selulose nabyo bihora binozwa. Guhitamo neza no gukoresha neza eta ya selulose bizamura cyane ireme ry'ibicuruzwa bya sima no kunoza imikorere y'ubwubatsi, ari na cyo cyerekezo cy'ingenzi mu iterambere ry'ibikoresho by'ubwubatsi ririho ubu.
