Polycarboxylate water reduction (PCE) muri sima

Imashini igabanya amazi ya polycarboxylate(PCE)ni ubwoko bushya bw'ibikoresho bigabanya amazi neza cyane, bikoreshwa cyane kandi bikora neza cyane mu bikoresho bigezweho bishingiye kuri sima. Bikoreshwa cyane mu gukora sima ivanze neza, sima yigenga, ibikoresho byo gusya, sima yo gusana na sima ikora neza.

1. Uburyo bw'ibikorwa

Polycarboxylate water reducer ni ubwoko bwa surfactant ifite molekile nyinshi irangwa n'iminyururu yo ku ruhande rwa polyether n'iminyururu mikuru ya aside carboxylic. Ubushobozi bwayo bwo kugabanya no gukwirakwiza amazi buturuka ahanini ku bintu bibiri:

1.1. Gutera imbaraga hakoreshejwe amashanyarazi

Uruhererekane rw'ingenzi rwa molekile ya Polycarboxylate igabanya amazi rugizwe n'amatsinda menshi ya carboxyl (-COOH), ashyirwa muri iyoni mu kirere cya alkaline kugira ngo akore radicals za carboxylate (-COO⁻), zihambirwa ku buso bw'uduce twa sima, bigatuma uduce dutwara umuriro umwe, bityo tukirukanana kandi bigatuma uduce twa sima dukwirakwira.

1.2. Ingaruka zo kubangamira sterike

Iminyururu yo ku ruhande rwa polyether nka polyoxyethylene groups (PEO) ibuza uduce twa sima kongera kwiteranya binyuze mu kubangamira sterique, bityo ikongera igihe cyo gukwirakwira. Iyi miterere ni myiza cyane kurusha naphthalene isanzwe na aliphatic water reduction.

2. Uruhare rw'ingenzi mu gusya sima

2.1. Bituma habaho imikorere myiza cyane

Iyo igipimo cy’amazi na sima kidahinduka, PCE ishobora kongera cyane uburyo sima itemba, bigatuma byoroha kubaka no gukwirakwiza neza, cyane cyane ikwiriye ibikoresho byo kwihuza na sima n’ibikoresho byo gusya.

2.2. Kugabanya cyane ikoreshwa ry'amazi

PCE ishobora kugabanya amazi avangaho ku kigero cya 20%-35% idahinduye imiterere y'amazi, bityo ikongera ubucucike n'imbaraga bya mortiweri kandi igakomeza kuramba.

2.3. Kunoza uburyo amazi abikwa n'imikorere y'inyubako

Mu gukwirakwiza ibice bya sima ku buryo bungana, PCE ishobora kugabanya amazi ava mu mazi no kuyatandukanya, bigatuma sima ikomera, ibyo bikaba byiza mu kubungabunga no kongera imbaraga.

2.4. Guteza imbere uburyo bwo guhumeka neza kw'isima

Kugabanya ukwivanga kw'uduce twa sima no kubireka bigahura neza n'amazi bizafasha uburyo bumwe bwo guhumeka neza no gukura kw'imbaraga za sima mu gihe gito.

2.5. Kunoza imiterere y'imashini

Bitewe n’uko amazi menshi agabanuka kandi ikaba igizwe n’imiterere mito, sima ivanze na PCE ifite imbaraga zo gukanda no gupfunyika cyane cyane mu sima ikomeye cyane.

3. Ibyiza ku mikorere

Kugabanya amazi neza cyane: Ugereranyije n'imiti isanzwe igabanya amazi ishingiye kuri naphthalene na lignin, PCE ifite igipimo cyo kugabanya amazi kiri hejuru kandi ikora neza kurushaho.

Igipimo gito n'umusaruro mwinshi: Ubusanzwe igipimo ni 0.1%-0.3% gusa by'ibikoresho bitera sima, bishobora kugira ingaruka nziza zo kugabanya amazi.

Guhuza neza: Ishobora guhuzwa n'uburyo butandukanye bwa sima n'ibindi bivangwa, kandi irashobora guhinduka mu buryo burambuye.

Kurengera ibidukikije no kwirinda umwanda: Polycarboxylate igabanya amazi ni ikintu kibisi kandi kidahumanya ibidukikije gihuye n’ibikenewe mu iterambere rirambye rya none mu bwubatsi.

4. Imikorere mu bikorwa bifatika

4.1. Sima yo kwiyongerera ubushobozi

PCE ituma mortilage igira ubushobozi bwo kugenda neza no kwifata, ikaba ikwiriye gukurura ubutaka, gufunga no gusana.

4.2. Kole y'amatafari, sima yo mu bwoko bwa plaster ifite urwego rwo hasi

Kunoza imiterere y'inyubako, kongera uburyo ifatana n'urwego rw'ibanze, no kugabanya guturika.

4.3. Gusana mortier n'ibikoresho byo gusya

Gabanya igipimo cy’amazi na sima, wongere ubucucike n’imikorere y’imbaraga hakiri kare, bikwiranye n’imishinga ifite imbaraga nyinshi kandi ikenera amazi menshi.

5. Amabwiriza yo kwirinda gukoresha

5.1. Kugenzura igipimo

Igipimo gikabije gishobora gutera amazi menshi ya mortical, amazi atemba cyangwa igihe kirekire cyo gushyiraho, ibyo bikaba bigomba guhindurwa hashingiwe ku isuzuma.

5.2. Kwivanga n'ibindi bivange

PCE igomba gupimwa kugira ngo irebe niba ihuye n’ibikoresho bireta, ibikoresho bifasha mu guhumeka, nibindi kugira ngo hirindwe amakimbirane mu mikorere.

5.3. Ingaruka z'ibikoresho fatizo

Ubwoko bwa sima, uburyo umucanga utoshye, ubushyuhe n'ibindi bintu bigira ingaruka zikomeye ku ngaruka za PCE, kandi igipimo cy'imvange kigomba kunozwa hakurikijwe imiterere nyayo y'aho hantu.

5.4. Kubika no gutwara

PCE y'amazi igomba kuba irinda ubukonje, idaterwa n'izuba, kandi ifunze neza kugira ngo ibikwe, kandi iguma mu bubiko mu gihe cy'amezi 6; ibikomoka ku ifu bigomba kuba birinda ubushuhe.

Imashini igabanya amazi ya polycarboxylate igira uruhare rudasimburwa mu ibumba rya simahamwe n’ubushobozi bwayo bwo kugabanya amazi, gukwirakwiza neza no kubika neza ibidukikije. Hamwe n’iterambere rihoraho ry’ibikoresho by’ubwubatsi by’icyatsi kibisi n’ibirungo bikoresha ikoranabuhanga rihanitse, imiterere n’ikoranabuhanga ryo gukoresha PCE nabyo birimo kunozwa buri gihe. Gukoresha PCE mu buryo bushyize mu gaciro ntibishobora gusa kunoza imikorere ya birungo, ahubwo binafasha kugera ku ntego ebyiri zo kubungabunga ingufu no kugabanya imyuka ihumanya ikirere no kunoza ireme ry’ubwubatsi.
