Inyigo ku mikorere yo gufatana kw'ibikoresho bya sima bya basalt byunzwe na fibre hamwe n'imitsi ya BFRP

Ibintu by'ingenzi bigira ingaruka ku mikorere y'ubufatanye

1. Gupima ingano ya fibre n'uburebure bwayo

Ikoreshwa ry'imiti igabanya ubukana bw'ibiyobyabwenge (volume doping) Basalt Ubudodo bugufi bufite ingaruka zikomeye ku mbaraga zo guhuza, kandi ikizamini kigaragaza ko gukoresha doping ya 0.2% bigira ingaruka nziza ku mbaraga zo guhuza, kandi gukoresha doping nyinshi bishobora gutuma imikorere igabanuka bitewe no guhuza fibre.

Uburebure bwa fibre (urugero: 6mm na 18mm) budatanga ingaruka nyinshi ku mbaraga z'imigozi, ariko fibre ngufi zoroshye gukwirakwira kugira ngo bigabanye inenge zo hagati y'uruso.

2. Ubwoko bw'imbaraga za sima yasubiwemo

Kongera imbaraga za sima yasubiwemo (urugero, kuva kuri C30 kugeza kuri C40) byongera imbaraga z'imibanire hagati ya BGukomeza Frp n'umubumbe, ariko ukwiyongera ni guke, kandi aho uhurira hashobora kwangirika iyo imbaraga zirenze urugero.

3. Uburyo bwo kuvura no guhuza imbuga

Gutwika umucanga hejuru y'ubuso bwa BFRP Gukomeza bishobora kongera ubukana no kunoza imbaraga zo kuruma; kongeramo silane coupling agent bishobora kunoza uburyo imiti ihuza fibre na resin matrix no kugabanya interfacial slip.

Ibizamini n'uburyo bwo gukora ibintu bifatanye

1. Ikizamini cyo gusohoka hagati

Uburyo bwo gupfunyika kw'imigozi bwigwaga binyuze mu igerageza ryo gupfunyika, maze byagaragaye ko uburyo bwo kwangirika kw'imigozi bwari ahanini ugupfunyika kw'imitsi cyangwa gucikamo sima. insinga za basalt bishobora gutinda kwangirika kwa sima no kongera ubushobozi bwo kugenda.

Ingano isanzwe y'imbaraga z'imigozi ni 6-12 MPa, kandi agaciro kayo kagengwa n'ingano ya fibre, umurambararo wo gushimangira (urugero, mm 16) n'uburyo bwo gutunganya aho ihurira.

2. Uburyo bwo gukwirakwiza imigozi y'imyenda

Umuvuduko w'ubuhuza ukwirakwira mu buryo butari umurongo ugororotse ku burebure bw'ubuhuza, kandi umuvuduko w'ubuhuza uba uri ku mpera y'umutwaro. Icyitegererezo cy'inyigisho kigomba gusuzuma uburyo sima ikoresha fibre ihangana n'ingaruka zo gukururana kw'ubuhuza.

Ibyiza byo gukoresha n'ingero z'ubuhanga

1. Ubudahangarwa bw'inkongi no kuramba kwayo

Gukomeza BFRP bigumana imbaraga zirenga 90% by'imibanire yayo mu bidukikije birimo isuri ya chloride ion (urugero, ikoranabuhanga ryo mu mazi), ibyo bikaba ari byiza cyane kurusha ibyuma na fiberglass reinforcement bar.

Urugero: Ikiraro cya Qingdao Cross-Sea cyakoresheje inyongeramusaruro ya BFRP kugira ngo gisimbuze inyongeramusaruro y'icyuma, kandi igihe cyo kubaho cyayo cyongerewe kugeza ku myaka irenga 100.

2. Imikorere yoroheje n'imitingito

Ubucucike bw'inkunga ya BFRP ni 1/4 cy'icyuma, gishobora gukoreshwa mu gushimangira imiringa ya beto kugira ngo kigabanye uburemere bw'inyubako ku kigero cya 20%-30%, kandi icyarimwe cyongere ubushobozi bwo gukoresha ingufu za sima binyuze mu gupfunyika insinga.

Imbogamizi zihari n'icyerekezo cyo kunoza imikorere

1. Gukomeza ubufatanye hagati y'uruso n'uruso

Ikibazo gihari: Uburyo bwo guhuza imigozi na sima bushobora gushwanyuka bitewe n’ubwinshi bw’imihangayiko, kandi hakenewe gukorwa ibikoresho bihuza nano-modified interfacial (urugero, nano-SiO₂ doped) kugira ngo byongere ubushobozi bwo guhuza imiti.

2. Imikorere n'amahame by'igihe kirekire

Kutagira amakuru y’igihe kirekire ku bijyanye n’ubushyuhe bwinshi n’ubushuhe bwinshi (urugero: imyaka irenga 10), ibizamini byihuse byo gusaza birakenewe kugira ngo bigenzurwe; imiterere y’imiterere ntabwo irakwirakwira mu bihugu bitandukanye, kandi nubwo Ubushinwa bwashyize ahagaragara amahame ya GB/T 38143-2019, amabwiriza y’imiterere y’imiterere aracyakeneye kunozwa.

3. Igishushanyo mbonera cy'ubufatanye mu buryo bwinshi

Mu gihe kiri imbere, dushobora gusuzuma ikoranabuhanga rivanze rya BFRP gushimangira no gushimangira ibyuma/fiber ya karuboni kugira ngo hubakwe ibintu bivanze kandi biringanize imbaraga n'ubushobozi bwo gukora ibintu.

Amabwiriza y'ubushakashatsi bw'ejo hazaza  

1. Igenzura ry'ubwenge n'igenamiterere ry'ikoranabuhanga

Utumashini tw’ikoranabuhanga rya fiber optique twashyizwe mu mitsi ya BFRP, gukurikirana mu buryo nyabwo uburyo bwo gukurura imigozi n’iterambere ry’imitsi, hamwe no gukoresha uburyo bwo gupima ibintu kugira ngo imiterere irusheho kuba myiza.

2. Uburyo bwo gutegura ikoreshwa rya karubone nkeya

Gabanya ubushyuhe bwa basalt fibre no gukurura ubushyuhe (ubu buri hagati ya 1400-1500 ℃), iterambere rya resin ikora ubushyuhe buke kugira ngo igabanye ikoreshwa ry'ingufu.

3. Gukoresha neza ibikoresho byasubiwemo

Huza imyanda y’ubwubatsi ikoreshwa mu kongera gukoreshwa n’imyanda ya basalt kugira ngo uteze imbere uburyo bw’ibikoresho by’ubwubatsi bishaje “bishobora kongera gukoreshwa” kandi ugabanye ikoreshwa ry’umutungo.

Incamake

Ubushakashatsi ku mikorere y'ubuhuza bw'ibikoresho bya sima bya basalt-reinforced fibre na BFRP Imitsi y'uruti yageze ku musaruro mu cyiciro ku kindi, ariko kuyikoresha mu buryo bunini biracyakeneye guca mu mbogamizi zo kunoza imiterere y'uruti rw'uruti, kugenzura uburambe bw'igihe kirekire no gushushanya neza. Mu gihe kizaza, binyuze mu guhanga udushya mu nzego zitandukanye (urugero: ibikoresho by'ubuhanga, inzira nke zikoresha karubone), byitezwe ko izagera ku iterambere mu ikoranabuhanga mu bijyanye n'ubuhanga bwo mu mazi no gukomeza imitingito, no gufasha iterambere ry'inyubako zirambye.
