Incamake:
Inganda z'ubwubatsi zigira uruhare runini mu kurema isi ya none, aho sima ari yo shingiro ry'inyubako. Mu myaka myinshi, abashakashatsi n'abahanga bakomeje gushaka uburyo bwo kunoza ubwiza n'imikorere ya sima. Imwe mu nzira nziza irimo kongeramo inyongeramusaruro, aho calcium formate yamenyekanye cyane.
menyekanisha:
Sima ni igice cy'ingenzi mu bwubatsi kandi isaba kunoza buri gihe kugira ngo ihuze n'impinduka mu nganda. Kongeramo inyongeramusaruro byagaragaye ko ari ingamba nziza yo kunoza ibice bitandukanye bya sima. Formate ya kalisiyumu, ikorwa n'uburyo kalisiyumu ikora na aside formike, yakuruye ibitekerezo ku bushobozi bwayo bwo kunoza imiterere ya sima. Iyi nkuru igamije gusobanura uburyo formate ya kalisiyumu igira ingaruka nziza ku bwiza n'imikorere ya sima.
Imiterere ya calcium formate:
Mbere yo gusuzuma ingaruka za formate ya kalisiyumu kuri sima, ni ngombwa gusobanukirwa imiterere y'iyi nyongeramusaruro. Formate ya kalisiyumu ni ifu y'umweru ya kristu ifite formula ya kinyabutabire ya Ca (HCOO)2. Irashonga mu mazi kandi ifite imiterere ya hygroscopic. Uruvange rwihariye rwa iyoni ya kalisiyumu na formate rutanga imiterere yihariye y'iyi mvange, bigatuma ikoreshwa mu buryo butandukanye, harimo no kunoza sima.
Uburyo:
Gushyira formate ya kalisiyumu mu mvange ya sima bitanga uburyo butandukanye butuma imikorere irushaho kuba myiza. Uburyo bumwe bunini burimo kwihuta mu gutonyanga sima. Formate ya kalisiyumu ikora nk'umusemburo, igatuma habaho hydrate nka calcium silicate hydrate (CSH) na ettringite. Uku kwihuta gutuma habaho igihe cyo gushyiraho ibintu vuba no kongera imbaraga mu gihe gito.
Byongeye kandi, formate ya kalisiyumu ikora nk'ahantu ho gutera amazi mu kirere, bigira ingaruka ku miterere y'icyuma cya sima. Uku guhinduka gutuma amazi akwirakwira cyane kandi akwirakwira neza, bigafasha mu kunoza kuramba no kugabanya kwinjira.
Byongeye kandi, calcium formate igira uruhare mu ihinduka rya pozzolanic, aho ihura na calcium hydroxide ikarema gel y'inyongera ya CSH. Iyi reaction ntigira uruhare mu iterambere ry'imbaraga gusa ahubwo inagabanya ibyago byo gutinda kwa ettringite (DEF), ikintu gishobora kwangiza kuramba kwa sima igihe kirekire.
Kunoza ubuziranenge bwa sima:
Gutera imbere kw'imbaraga hakiri kare:
Ubushobozi bwa calcium formate bwo kwihutisha amazi ya sima butuma habaho iterambere rikomeye mu iterambere ry’ingufu hakiri kare. Ibi ni ingenzi ku mishinga y’ubwubatsi aho imbaraga zigomba kuboneka vuba. Igihe cyo kwihutisha imiterere giterwa na calcium formate gishobora gutuma imashini zikurwaho vuba kandi zigatera imbere vuba mu bwubatsi.
Kongera igihe cyo kuramba:
Formate ya kalisiyumu yongerwamo kugira ngo ihindure imiterere ya sima, bigatuma ibikoresho biramba. Ubwinshi bw'ibinyabutabire n'uburyo bumwe bwo gukwirakwiza amazi mu buryo bumwe bigira uruhare mu kongera ubudahangarwa ku bitero bya shimi, gukonja no kwangirika. Kubwibyo, imiterere ya sima ivuwe na formate ya kalisiyumu iramba.
Kugabanya ubushobozi bwo kwinjira mu mubiri:
Kimwe mu bintu by'ingenzi bigira ingaruka ku kuramba kwa sima ni ubushobozi bwayo bwo kwinjira. Formate ya kalisiyumu igabanya ubushobozi bwo kwinjira binyuze mu kugira ingaruka ku miterere y'imyobo ya sima. Ikorwa rya matrix nini ifite imyenge mito rigabanya uburyo amazi n'ibintu bikaze byinjira, bityo byongera ubushobozi bwa sima bwo kurwanya kwangirika.
Kugabanya ingaruka za Alkali Silika Reaction (ASR):
Ubushakashatsi bwagaragaje ko formate ya kalisiyumu ishobora kugabanya ibyago byo kwangirika kwa alkali-silica, ikintu kibi gishobora gutuma habaho kubyimba kwa gel no kwangirika muri sima. Binyuze mu kugira ingaruka ku miterere y'imyobo n'imiterere y'imiti ya sima, formate ya kalisiyumu ifasha kugabanya ibyago byo kwangirika bifitanye isano na ASR.
Kongera imikorere:
Uburyo bworoshye bwo gukoresha mashini:
Ingaruka za calcium formate ku gutonyanga sima zigira ingaruka nziza ku buryo sima nshya ikora neza. Igihe cyagenwe cyo kwihutisha no kongera uburyo amazi akoreshwa bifasha kunoza imiterere y'amazi, bigafasha gushyira sima mu mwanya wayo no kuyicunga. Ibi ni ingirakamaro cyane cyane aho uburyo bworoshye bwo kuyishyira mu mwanya wayo ari ingenzi cyane.
kugenzura ubushyuhe:
Gukoresha formate ya kalisiyumu muri sima bifasha kugabanya ingaruka z'ubushyuhe bukabije mu gihe cyo gushya. Kwihutisha igihe cyo gushyiraho formate ya kalisiyumu bishobora kwihutisha iterambere ry'imbaraga no kugabanya ibyago bya sima ku bibazo bifitanye isano n'ubushyuhe nko gucika kw'ubushyuhe.
Ibitekerezo ku bijyanye no kurambye:
Formate ya kalisiyumu ifite imiterere ijyanye n'intego z'ubudahangarwa mu nganda z'ubwubatsi. Uburyo ikoramo ibintu bidasanzwe byoroshya ikoreshwa ry'imyanda, kandi ingaruka zayo ku kuramba no kuramba kwayo zigira uruhare mu kugabanya ingaruka ku bidukikije zijyanye no gusimbuza no gusana inyubako zishaje.
Imbogamizi n'ibyo umuntu agomba gutekerezaho:
Nubwo ibyiza byo gushyira formate ya kalisiyumu muri sima bigaragara, imbogamizi zishobora kubaho n'imbogamizi zigomba kwitabwaho. Ibi bishobora kuba birimo kwiyongera kw'ikiguzi, uburyo bishobora gukoreshwa n'izindi mvange, ndetse no gukenera kugenzura neza igipimo kugira ngo hirindwe ingaruka mbi. Byongeye kandi, imikorere n'uburambe bya beto ya kalisiyumu itunganyijwe mu bihe runaka by'ibidukikije bisaba ubushakashatsi n'ubushakashatsi bw'ibanze.
mu gusoza:
Gushyira calcium formate muri sima ni uburyo bwiza bwo kunoza ubwiza n'imikorere y'iyi mashini y'ingenzi. Binyuze mu buryo bwayo bunyuranye bwo gukora, calcium formate yihutisha amazi, inoza imiterere mito kandi igatanga imiterere myinshi ishimishije, harimo no guteza imbere imbaraga hakiri kare, kongera kuramba no kugabanya ubushobozi bwo kwinjira mu mazu. Uko inganda z'ubwubatsi zikomeza gutera imbere, uruhare rw'inyongera nka calcium formate mu kunoza imiterere ya sima rushobora kwiyongera cyane. Ubushakashatsi n'ikoreshwa mu buryo bufatika nta gushidikanya ko bizagaragaza ubushobozi bwose n'ikoreshwa ryiza rya calcium formate mu miterere ya sima, bigategura inzira yo kubaka inyubako zikomeye kandi zirambye.
