Selirulose ya Methyl Hydroxyethyl (MHEC), eteri isanzwe ya selulosi mu bikoresho by'ubwubatsi, ikoreshwa cyane mu byuma byumye bivanze, kole z'amatafari, ifu ya putty, na mortiers zishyushya ubushyuhe bitewe n'uko zikomera, zibika amazi, kandi zigatuma zikora neza. Injeniyeri nyinshi zihangayikishijwe n'ikibazo cy'ingenzi iyo zikoresha MHEC: Ni iki gipimo cya MHEC gisabwa muri mortiers za sima?
1. Ingano y'igipimo cya MHEC gisabwa mu ibumba rya sima
Ubusanzwe, igipimo cyo kongeramo MHEC kuri sima kiri hasi, nyamara gishobora kunoza cyane imikorere ya sima. Hashingiwe ku bunararibonye mu nganda n'amakuru ya tekiniki, ingano isabwa muri rusange ni:
Sima isanzwe: hafi 0.2‰–0.6‰ (ni ukuvuga garama 200–600 kuri toni y'ifu yumye).
Gusigwa ibumba n'ibumba ry'amabuye: ubusanzwe biri hagati ya 0.3‰–0.5‰.
Utwuma duto two gukamura cyangwa utundi twihariye: birashoboka ko hakenerwa ingano iri hejuru gato, hafi 0.4‰–0.7‰. Gufata amatafari cyangwa utundi twinshi: Igipimo gishobora kongerwa kikagera kuri 0.6‰–1.0‰ uko bikenewe, ariko gake cyane kirenga 1%.
Icyitonderwa ni uko igipimo cya MHEC gisabwa atari agaciro gahoraho kandi kigirwaho ingaruka n'ibintu nk'ibigize sima, ubwoko bwa sima, ubunini bw'ibiceri, ubushyuhe n'ubushuhe. Kubwibyo, mu musaruro nyawo, igipimo cyiza gikunze kugenwa binyuze mu bizamini by'igerageza.
2. Ibintu bigira ingaruka ku gipimo cyagenwe
2.1. Ubwoko bwa sima n'ingano yayo
Imikorere n'ubunini bwa sima, ndetse n'ingano y'ibivangwa (nk'ivu ry'umukungugu n'ifu y'ubutare), byose bigira ingaruka ku gipimo cyiza cya MHEC. Mortars zikora cyane kandi zikoresha amazi menshi akenshi zikenera ether nyinshi ya cellulose kugira ngo zigumane amazi.
2.2. Imiterere y'umucanga n'ibikoresho byo kuzura
Ikwirakwira ry'uduce tw'umucanga n'ubugari bwawo bigira ingaruka zikomeye ku ikenerwa ry'amazi. Umucanga muto cyangwa mortiers zirimo utuzu duto duto akenshi bisaba ko ingano ya MHEC yiyongera kugira ngo ikomeze kuba myiza kandi ikore neza.
2.3. Imiterere y'Ubwubatsi
Mu bushyuhe bwinshi, ubushuhe buke, cyangwa umuyaga mwinshi, ubushuhe bwa mortier buhita bushira, bigasaba ko ingano ya MHEC yongera kugira ngo amazi akomeze kugumana kandi yongere igihe cyo gufungura.
2.4. Imikorere y'intego
Niba amazi agumana kandi agakomera, igipimo gishobora kongerwa ku rugero ruciriritse.
Niba ubushobozi bwo gukora ari bwo bw'ingenzi, ingano nto y'umuti irahagije.
Ku birebana n'uburyo bwo gushyiramo ibintu bito (nk'amatafari yo gushushanya), kongera ingano ya MHEC mu buryo bukwiye ni ingenzi cyane.
3. Ingaruka za MHEC mu ibumba
Kongeramo MHEC mu buryo bwumvikana bishobora kongera cyane imiterere ya mortilage, harimo:
3.1. Kubungabunga Amazi mu buryo bwiza
Cellulose ether ikora umuti umwe kandi urimo uburyaryate muri mortilage, igafunga neza ubushuhe kandi ikarinda amazi ya sima kutagira ingano, bityo ikongera imbaraga.
3.2. Guteza imbere ubushobozi bwo gukora no gukora neza
Urusenda rugenda rworoha kandi rugafata neza, bigatuma byoroha gukwirakwira, gushyiramo, no gufungana mu gihe cyo kubaka, bigagabanya kuva amaraso no gutandukana kw'ibice.
3.3. Gukomera cyane no kudacika intege
Mu gihe cyo kubaka uhagaze, sima ntabwo ishobora kugwa cyane kandi ihuza neza n'ubuso bw'icyuma gikozwe mu cyuma, mu byuma bikozwe mu cyuma cyangwa mu byuma bikingira.
3.4. Igihe kirekire cyo gufungura
MHEC igabanya umuvuduko w'amazi mu gishishwa, bigatuma abakozi b'ubwubatsi babona umwanya wo kumenyera no kunoza imikorere y'ubwubatsi.
3.5. Imikorere myiza ya Mortar muri rusange
Ibi birimo kudacika kw'imivuniko, kuramba, n'ubwiza bw'ubuso, bituma sima ifite imbaraga kandi ihamye nyuma yo gukomera.
4. Inama ku ikoreshwa
Isuzuma Mbere yo Gupima: Bitewe n'ubwoko bwinshi bw'imiti, ni byiza gukora ibizamini byo muri laboratwari kugira ngo hamenyekane ingano nziza.
Irinde gukoresha MHEC cyane: Kongeramo MHEC cyane bishobora gutuma mortilage ikomera cyane, bigatuma kuyikoresha bigorana ndetse bikanagira ingaruka ku bukonje.
Menya neza ko ibimera bikwirakwira mu buryo bumwe: Mu gihe cyo kuvanga byumye, menya neza ko MHEC ivanze neza n'umucanga na sima kugira ngo hirindwe ko bishonga.
Igipimo cya MHEC gisabwaMuri sima isanzwe iri hagati ya 0.2 na 0.6, aho sima zidasanzwe zituma ziyongera neza zikagera kuri 0.7 kugeza kuri 1.0. Igipimo cyihariye kigomba kunozwa hashingiwe ku bwoko bwa sima, imiterere y'ibikoresho fatizo, n'aho bubaka. Gukoresha neza MHEC ntibituma amazi ya sima agumana gusa, ubushobozi bwo gukora, n'imikorere y'ubwubatsi, ahubwo binatuma imbaraga n'ubudahangarwa bikomera. Ni ikintu cy'ingenzi mu miterere ya sima igezweho.
