IGABANYA AMAZI YO MU BURYO BWO HEJURU (SMF)ni amashanyarazi ashongeshwa n'amazi anion nyinshi zikozwe muri polymer. SMF ifite ubushobozi bwo kuyungurura amazi no kuyagabanya. SMF ni imwe mu myobo iri mu bikoresho bigabanya amazi bya sima. Ibintu by'ingenzi ni: umweru, amazi menshi, ubwoko bw'umwuka udakoresha umwuka, ingano nto ya chloride idafite ingese ku byuma, kandi ishobora kwihuza neza na sima zitandukanye. Nyuma yo gukoresha ibikoresho bigabanya amazi, imbaraga za mbere n'ingufu bya sima byariyongereye cyane, imiterere y'inyubako n'amazi byarushijeho kuba byiza, kandi kubungabunga umwuka w'umwuka byarahinduwe.
Mu gihe sima iguye, muri rusange ibintu bimwe bishobora kugabanya cyane imvange y'amazi ivanze yitwa "high efficiency water reducing agent". Mu gihe kimwe, imvange imwe, ikoreshwa ry'amazi n'amazi bishobora kugabanukaho ibirenze 15%.
Iterambere amateka:Icyiciro cya mbere cy’umuti ugabanya amazi neza cyane hamwe na superplasticizer ishingiye kuri amine resin cyakozwe mu ntangiriro za 1960. Bitewe n’imikorere y’umuti ugabanya amazi usanzwe wakozwe na lignesulfonate mu mpera za 1930, uzwi kandi nka superplasticizer. Icyiciro cya kabiri cy’umuti ugabanya amazi neza cyane ni amino sulfonate, nubwo ukurikije uko ibintu byagenze nyuma y’ikiciro cya gatatu cya superplasticizer - polycarboxylic acid series. Copolymer ya graft ifite aside sulfonic na aside carboxylic ni yo y’ingenzi cyane mu kigero cya gatatu cy’umuti ugabanya amazi neza cyane, kandi imikorere yayo ni nayo mu muti ugabanya amazi neza cyane.
Ubwoko bw'ingenzi:Igipimo cyo kugabanya amazi gikoreshwa mu kugabanya amazi gishobora kugera kuri 20%. Ni ubwoko bwa naphthalene, melamine n'ibikoreshwa mu kugabanya amazi bigizwe nabyo, muri byo harimo naphthalene, ikaba ari yo ikoreshwa cyane, ikaba ingana na 67%. By'umwihariko, inyinshi mu bikoresho bikoreshwa mu kugabanya amazi bikoreshwa mu kugabanya amazi bishingiye kuri naphthalene nk'ibikoresho by'ibanze. Dukurikije ingano ya Na2SO4 muri naphthalene series superplasticizer, ishobora kugabanywamo ibicuruzwa bifite ubunini bwinshi (ibikubiye muri Na2SO4 < 3%), ibikubiye muri naphthalene series superplasticizer, bishobora kugabanywamo ibicuruzwa bifite ubunini bwinshi (ibikubiye muri Na2SO4 < 3%), ibikubiye muri naphthalene series superplasticizer 3%-10%) n'ibikubiye muri naphthalene series > 10%). Inganda nyinshi zikora naphthalene superplasticizer zifite ubushobozi bwo kugenzura ibikubiye muri Na2SO4 biri munsi ya 3%, kandi zimwe mu nganda ziteye imbere zishobora no kugenzura ibikubiye muri NA2SO4 biri munsi ya 0.4%.
Uruhererekane rw'ibikoresho bigabanya amazi bya Naphthalene ni rwo runini mu gihugu cyacu rukora, ni rwo rukoreshwa cyane mu kugabanya amazi neza cyane (rufite ingano irenga 70% by'ingano y'ibikoresho bigabanya amazi), rurangwa no kugabanya amazi menshi (15% ~ 25%), nta mwuka urimo, nta ngaruka nyinshi ku gihe cyo gushyiraho, ubushobozi bwo guhuza neza na sima, rushobora gukoreshwa n'ibindi bikoresho bitandukanye, igiciro nacyo ni gito cyane. Superplasticizer ya Naphthalene ikunze gukoreshwa mu gutegura sima ifite uburyo bwo kugenda bwinshi, imbaraga nyinshi n'imikorere myiza. Gutakaza sima hakoreshejwe superplasticizer ya naphthalene byihuta. Byongeye kandi, ubushobozi bwo guhuza amazi na naphthalene hamwe na sima imwe na imwe bugomba kunozwa.
Imitungo:Umuti ugabanya amazi neza cyane ugira ingaruka zikomeye ku isima, ushobora kunoza cyane urujya n'uruza rw'isima no kugwa kwa sima, mu gihe ugabanya cyane ikoreshwa ry'amazi, ukongera cyane ubushobozi bwo gukora bwa sima. Ariko superplasticizer imwe na imwe yihutisha gutakaza sima, kuvanga cyane bigabanya amazi. Umuti ugabanya amazi neza cyane ntabwo uhindura igihe cyo gushyiraho sima, kandi ugira ingaruka nke iyo ingano ari nini (ikoreshwa ry'umuti urenze urugero), ariko ntutinza gukura kwa sima ikomeye hakiri kare.
Bishobora kugabanya cyane ikoreshwa ry'amazi no kongera imbaraga za sima mu myaka itandukanye. Iyo imbaraga zigumanye, sima ishobora kuzigama 10% cyangwa irenga.
Ingano ya iyoni ya kloride ni nto, nta ngaruka ya corruption ku cyuma. Ishobora kongera ubushobozi bwo kutamena, kurwanya frigo no kurwanya corruption ya sima, no kongera réhabilitation ya sima.
UBUSABIZI:
1, Ikwiriye ubwoko bwose bw'ubwubatsi bw'inganda n'ubw'ibikorwa remezo, kubungabunga amazi, ubwikorezi, icyambu, imashini zitunganya ikoranabuhanga mu mujyi ndetse na sima ikomeye ikoreshwa mu gushushanya.
2, Ikwiriye beto ikomeye cyane, ikomeye cyane kandi iciriritse, hamwe n'ibikenewe kugira ngo ikomere hakiri kare, irwanya ubukonje buri hagati, beto nini y'amazi.
3, Bikwiriye ibikoresho bya sima byakozwe mbere mu gutunganya umwuka.
4, Ikwiriye ubwoko butandukanye bw'ibivange by'ibice bigabanya amazi (Master Batch).
