Igihe cyo gushyiraho sima ni ikintu cy'ingenzi kigira ingaruka ku bwiza bw'inyubako n'iterambere ryayo. Iyo igihe cyo gushyiraho ari kirekire cyane, bishobora gutuma imirimo yo kubaka itinda kandi bikangiza ubwiza bwa sima; iyo igihe cyo gushyiraho ari gito cyane, bishobora guteza ingorane mu kubaka sima no kugira ingaruka ku ngaruka z'umushinga. Kugira ngo hakosorwe igihe cyo gushyiraho sima, gukoresha ibintu bivanze byabaye uburyo busanzwe mu gukora sima igezweho.Hydroxyethyl Methyl Cellulose (HEMC), nk'ikintu gisanzwe gikoreshwa mu guhindurwa kwa selulosi, gikoreshwa cyane mu bivange bya beto kandi gishobora kugira ingaruka ku miterere y'amazi, uburyo amazi abikwamo, igihe cyo gushyiraho beto n'ibindi bintu biyiranga.1. Imiterere y'ibanze ya HEMC
HEMC ni selulosi yahinduwe, ubusanzwe ikorwa muri selulosi karemano binyuze mu mikorere ya ethylation na methylation. Ifite ubushobozi bwo gushonga neza mu mazi, gukomera, kubika amazi no kubika gel, bityo ikoreshwa cyane mu bwubatsi, gusiga irangi, imiti ya buri munsi n'ibindi bikorwa. Muri sima, HEMC ikunze gukoreshwa nk'umuti ugabanya ubukana, umuti ugabanya amazi no kugenzura rheology, ushobora kunoza imikorere ya sima, kongera gufatana no kongera igihe cyo kuyishyiraho.
2. Ingaruka za HEMC ku gihe cyo gushyiraho sima
Gutinda gushyiraho igihe
Nk’ikivange cya selulosi, HEMC irimo umubare munini w’amatsinda akunda amazi mu miterere yayo ya molekile, ashobora gukorana n’uturemangingo tw’amazi kugira ngo akore hydrate ihamye, bityo bigatinza inzira yo gutonyanga sima ku rugero runaka. Uburyo amazi akoreshwa muri sima ni bwo buryo bw’ingenzi bwo gukonja kwa sima, kandi kongeramo HEMC bishobora kugira ingaruka ku gihe cyo gushyiraho ibintu binyuze mu buryo bukurikira:
Kongera ubushobozi bwo kubika amazi: HEMC ishobora kunoza cyane uburyo amazi ya sima abikwa, igabanye umuvuduko w’amazi ava mu kirere, kandi ikongera igihe cyo kunywa sima. Binyuze mu kubika amazi, HEMC ishobora kwirinda gutakaza amazi menshi, bityo igatinza igihe cyo kuyashyiraho mbere n’icya nyuma.
Kugabanya ubushyuhe: HEMC ishobora kubuza uburyo ibice bya sima bigongana kandi bigabanyije ubushyuhe binyuze mu kongera ubukana bwa sima no kugabanya umuvuduko w'ingendo z'ibice bya sima. Kugabanya ubushyuhe bifasha gutinza igihe cyo gushyiraho sima.
Guhindura imikorere y'imitsi: HEMC ishobora guhindura imiterere y'imitsi ya sima, kongera ubukana bwayo, no gutuma sima ikomeza kugenda neza mu gihe cya mbere, birinda ingorane mu bwubatsi ziterwa no gufungana cyane.
Ibintu bigira ingaruka ku buzima
Ingaruka zaHEMCKugena igihe ntibifitanye isano ya hafi n'ingano yabyo gusa, ahubwo binagira ingaruka ku bindi bintu byo hanze:
Uburemere bwa molekile n'urwego rwo gusimbuza HEMC: Uburemere bwa molekile n'urwego rwo gusimbuza (urwego rwo gusimbuza ethyl na methyl) bya HEMC bigira ingaruka zikomeye ku mikorere yayo. HEMC ifite uburemere bwinshi bwa molekile n'urwego rwo gusimbuza muri rusange ishobora gukora imiterere ikomeye y'urusobe rw'amazi, ikagaragaza ubushobozi bwo kubika amazi no kuyagwingira, bityo ingaruka zo gutinda ku gihe cyo gushyiraho ibintu zikaba ingenzi cyane.
Ubwoko bwa sima: Ubwoko butandukanye bwa sima bufite igipimo gitandukanye cy’amazi, bityo ingaruka za HEMC ku buryo butandukanye bwa sima nazo ziratandukanye. Sima isanzwe ya Portland ifite igipimo cy’amazi cyihuta, mu gihe sima imwe ikoresha ubushyuhe buke cyangwa sima yihariye ifite igipimo gito cy’amazi, kandi uruhare rwa HEMC muri ubwo buryo rushobora kuba rugaragara cyane.
Imiterere y'ibidukikije: Imiterere y'ibidukikije nk'ubushyuhe n'ubushuhe bigira ingaruka zikomeye ku gihe cyo gushyiraho sima. Ubushyuhe bwinshi buzihutisha uburyo sima ikoresha amazi menshi, bigatuma igihe cyo gushyiraho kigabanuka, kandi ingaruka za HEMC mu bidukikije ubushyuhe bwinshi zishobora kugabanuka. Ahubwo, mu bidukikije ubushyuhe buke, ingaruka zo gutinda za HEMC zishobora kugaragara cyane.
Ubucucike bwa HEMC: Ubucucike bwa HEMC bugena neza urwego rw'ingaruka zayo kuri sima. Ubucucike bwinshi bwa HEMC bushobora kongera cyane uburyo amazi abikwamo na rheology ya sima, bityo bigatinza igihe cyo kuyishyiraho, ariko HEMC irenze urugero ishobora gutera ubucucike bubi bwa sima no kugira ingaruka ku mikorere y'inyubako.
Ingaruka za HEMC zihuriza hamwe n'izindi mvange
HEMC ikoreshwa n'izindi mvange (nk'izigabanya amazi, izigabanya ubushyuhe, n'izindi) kugira ngo ihindure neza imikorere ya sima. Ku bufatanye n'izigabanya ubushyuhe, ingaruka zo gutinda kwa HEMC zishobora kongerwa. Urugero, ingaruka zo guhuza zimwe na zimwe za mvunge nka fosfeti n'isukari hamwe na HEMC zishobora kongera cyane igihe cyo gushyiraho sima, kikaba gikwiriye imishinga yihariye mu bihe bishyushye cyangwa gisaba igihe kirekire cyo kubaka.
3. Izindi ngaruka za HEMC ku miterere ya sima
Uretse gutinza igihe cyo gushyiraho, HEMC ifite n'ingaruka zikomeye ku yindi miterere ya sima. Urugero, HEMC ishobora kongera uburyo sima itemba, irwanya gutandukanya, ikora neza mu gupompa no kuramba kwayo. Mu gihe ihindura igihe cyo gushyiraho, ingaruka zo gukomera no kubika amazi za HEMC zishobora no gukumira gutandukanya cyangwa kuva amaraso muri sima, no kunoza ubwiza n'ubudahangarwa bya sima muri rusange.
Hydroxyethyl methylcellulose (HEMC) ishobora gutinza igihe cyo gushyiraho sima binyuze mu kubika amazi neza, gukuba kwayo no kugabanya imikorere yayo. Urwego rw'ingaruka za HEMC ruterwa n'ibintu nk'uburemere bwayo bwa molekile, urugero rwo gusimbuza, ubwoko bwa sima, imvange yayo n'imiterere y'ibidukikije. Mu kugenzura neza ingano n'ingano ya HEMC, igihe cyo gushyiraho gishobora kongerwa neza mu gihe hakorwa ibishoboka byose kugira ngo sima ikore neza, kandi ubushobozi bwo gukora no kuramba kwa sima bushobora kunozwa. Ariko, gukoresha HEMC cyane bishobora no kuzana ingaruka mbi, nko kuba amazi adahagije cyangwa amazi adahagije, bityo igomba gukoreshwa witonze hakurikijwe ibikenewe by'ubuhanga.
