Ubushakashatsi kuri fibre ya basalt mubikorwa byubwubatsi
1.Icyerekezo kinini cyo gusaba
- Ibikoresho byubaka
Fibre beto (BFRC): Gucisha bugufi Fibres (6-24mm) ivangwa muri beto (kuvanga amafaranga 0.1% -0.5%), bishobora guteza imbere cyane kurwanya guhangana (kugabanya ubugari bwa 30% -50%), kurwanya ingaruka (kwiyongera inshuro 2-3), no kuramba (kurwanya amagare ya freze-thaw byiyongereyeho 40%).
Gusimbuza ibyuma byubaka ibyuma: Mubidukikije byangirika (urugero nka marine engineering), basalt fibre ikomeza utubari (BFRP) irashobora gusimbuza ibyuma kugirango wirinde ibibazo bya ruswa. Kurugero, ikoreshwa rya bfrp gushimangirwa muri piers yikiraro cyambukiranya inyanja muri Qingdao biteganijwe ko cyongerera igihe cyacyo imyaka irenga 100.
- Gushimangira ibyubaka no gusana
Imyenda ya Fibre / Mesh Kongera imbaraga: Umwenda wa fibre ya Basalt (imbaraga za tensile ≥2000MPa) zometse hejuru yibiti hamwe ninkingi, bishobora kongera ubushobozi bwo gutwara imitwaro 20% -30%. Kurugero, nyuma yikiraro gishaje muri Sichuan gishimangiwe nigitambaro cya BF, igipimo cyumutwaro kizamurwa kuva mumihanda-II kugera mucyiciro cya I.
Gushimangira imitingito: fibre-yongerewe imbaraga (BFRP.
- Imiterere mishya
Basalt fibre-polymer sandwich: ikoreshwa mubisenge byoroheje hamwe nurukuta rwibice, hamwe nimbaraga nyinshi hamwe nubushyuhe bwumuriro (ubushyuhe bwumuriro ≤ 0.05 W / mK).
Ibikoresho byo gucapa 3D: fibre-ibikoresho bya sima byongerewe imbaraga birashobora kumenya imiterere igoye yo gucapa no kugabanya imyanda yo kubaka.
2.Ikoranabuhanga rya Tekinike hamwe namakuru yibanze
| Ibipimo byerekana imikorere | Fibre | Kugereranya ibikoresho (fibre yikirahure) |
| Imbaraga | 3000-4800 MPa | 2000-3500 MPa |
| Kurwanya Alkali (pH = 13) | Imbaraga zo kugumana ≥90% | Fibre yikirahure: kugumana imbaraga ≤ 50% |
| Ibyiza bidukikije: gukoresha ingufu zitanga umusaruro ni 30% gusa ya fibre yibirahure, kandi birashobora gukoreshwa 100%. | ||
3.Gushakisha Amajyambere n'imanza zisanzwe
- Ubushakashatsi bwo murugo
Kaminuza ya Tsinghua: yateje imbere basalt fibre-nano-silika igizwe na beto yahinduwe hamwe na 25% imbaraga zo kwikuramo kwiyongera no kugabanya 60% ya chloride ion.
Kaminuza yo mu majyepfo y’iburasirazuba: isabwa BF / epoxy resin laminate ishimangiwe na tekinoroji ya beto ya tekinoroji, ubuzima bwumunaniro bwongerewe inshuro zirenga 3.
- Porogaramu mpuzamahanga
Japan
Uburayi: BF ikozwe muri beto yakoreshejwe mu marembo yo kurwanya umwuzure muri Venise, mu Butaliyani, ubuzima bwe bumara imyaka 50 mu kurwanya isuri y’amazi.
- Imanza zubwubatsi
Ubushinwa - Ikiraro cya Hong Kong-Zhuhai-Macao: Fibre ibikoresho byinshi bikoreshwa murwego rwo kurwanya ruswa ya piers zimwe, kugabanya ikiguzi cyo kubungabunga 30%.
Amerika - Agace ka San Francisco Bay Byihuta (BART): Umwenda wa BF ukoreshwa mugukomeza umurongo wa tunnel, kandi kurwanya ihindagurika byiyongereyeho 25%.
4.Ibibazo hamwe nicyerekezo kizaza
- Ibibazo biriho
Imikorere idahagije ihuza imikorere: intera iri hagati ya fibre na beto / resin ikunda kwamburwa, ibikoresho bishya byo guhuza (urugero, moderi ya silane) bigomba gutezwa imbere.
Kubura amakuru yigihe kirekire yimikorere: ibiranga creep biranga imbaraga za BF munsi yubushyuhe bwinshi nubushuhe bukabije (imyaka irenga 10 yamakuru aracyatunganye).
Uburinganire bwa sisitemu isanzwe: igishushanyo mbonera cy’ibikoresho bya BF mu bihugu bitandukanye ntikiramenyekana neza (Ubushinwa bwasohoye GB / T 38143-2019, ariko ibisobanuro birambuye bigomba gutunganywa).
- Icyerekezo cyubushakashatsi
Ubwenge bwa fibre yibikoresho: byashyizwemo ibyuma kugirango ugere kubuzima bwiza (urugero, kunanirwa, kwikuramo).
Tekinoroji yo gutegura icyatsi: gabanya gushonga no gushushanya ubushyuhe (kuri ubu ukeneye 1400-1500 ℃), kandi utezimbere inzira ya karubone.
Gushimangira byinshi-gushimangira imbaraga: kuvanga na fibre ya karubone hamwe nicyuma kugirango wubake ibintu bya gradient.
5. Incamake
Porogaramu ya fibre mubwubatsi bwa gisivili yavuye muri laboratoire yerekeza mubikorwa byubwubatsi, kandi ibiranga ibicuruzwa byangiza kandi bitangiza ibidukikije bihuye nibisabwa ku nyubako zicyatsi hagamijwe “karuboni ebyiri”. Mu bihe biri imbere, birakenewe guca mu buryo bunoze bwo kugenzura imiterere, kugenzura igihe kirekire no kugenzura ubundi buryo bw'ikoranabuhanga, kandi icyarimwe bigateza imbere kunoza imiterere y'ibishushanyo mbonera ndetse no guhuza inganda, kugira ngo byihutishe ikoreshwa ryayo rinini mu bikorwa remezo binini, ubwubatsi bwo mu nyanja, umutingito no gukumira ibiza n'ibindi bintu.
