Kafukufuku pa ulusi wa basalt mu ntchito zama engineering
1.Malangizo akuluakulu a ntchito
- Konkire kulimbikitsa zipangizo
Fiber Concrete (BFRC): Short-cut Basalt Fibers (6-24mm) ali osakaniza konkire (kusakaniza kuchuluka 0.1% -0.5%), amene akhoza kwambiri kusintha ming'alu kukana (kuchepetsa mng'alu m'lifupi ndi 30% -50%), kukana mphamvu (kuchuluka kwa 2-3 nthawi), ndi durability (amaundana-thaw kupalasa kukana chinawonjezeka ndi 40%).
Kubwezeretsanso zitsulo zolimbitsa zitsulo: M'malo owononga (monga uinjiniya wapamadzi), mipiringidzo ya basalt fiber reinforcing (Zithunzi za BFRP) amatha kusintha zitsulo zolimbitsa thupi kuti apewe zovuta za dzimbiri. Mwachitsanzo, kugwiritsa ntchito bfrp Kulimbitsa mlatho wodutsa panyanja ku Qingdao kukuyembekezeka kukulitsa moyo wake mpaka zaka 100.
- Kulimbikitsa ndi kukonza zomangamanga
Nsalu za Fiber / Mesh Reinforcement: Nsalu ya Basalt fiber (mphamvu yamatenda ≥2000MPa) imayikidwa pamwamba pa matabwa ndi mizati, zomwe zingathe kuwonjezera mphamvu yonyamula katundu ndi 20% -30%. Mwachitsanzo, mlatho wakale ku Sichuan utalimbikitsidwa ndi nsalu ya BF, kuchuluka kwa katundu kumakwezedwa kuchokera ku Highway-II kupita ku Class I.
Kulimbitsa zivomezi: zophatikizika zowonjezeredwa ndi fiber (Mtengo wa BFRP) mizati ya konkire yokulungidwa, yomwe imatha kupititsa patsogolo mphamvu yamagetsi ndi mphamvu yowonongeka, ndipo ndi yoyenera ku nyumba zomwe zili m'madera omwe amapezeka ndi zivomezi.
- Zomangamanga zatsopano
Masangweji a masangweji a Basalt fiber-polymer: amagwiritsidwa ntchito popanga madenga opepuka ndi makoma ogawa, okhala ndi mphamvu zonse komanso kutsekemera kwamafuta (kutentha kwamafuta ≤ 0.05 W/mK).
Zida zomangira zosindikizira za 3D: basalt fiber-Zida zolimbitsa simenti zimatha kuzindikira kusindikiza kwamapangidwe ovuta ndikuchepetsa zinyalala zomanga.
2.Technical Ubwino ndi Core Data
| Zizindikiro za Ntchito | Basalt fiber | Kuyerekeza zinthu (galasi CHIKWANGWANI) |
| Kulimba kwamakokedwe | 3000-4800 MPa | 2000-3500 MPa |
| Kukana kwa alkali (pH=13) | Kusunga mphamvu ≥90% | Ulusi wagalasi: kusunga mphamvu ≤ 50% |
| Ubwino wa chilengedwe: kugwiritsa ntchito mphamvu zopangira ndi 30% yokha ya fiber yamagalasi, ndipo imatha kusinthidwanso 100%. | ||
3.Research Progress and Typical Cases
- Kafukufuku wapakhomo
Yunivesite ya Tsinghua: idapanga konkriti yosinthidwa ya basalt fiber-nano-silica yokhala ndi 25% yowonjezera mphamvu yamphamvu ndi kuchepetsa 60% chloride ion permeability.
Southeast University: akufuna BF/epoxy resin laminate yolimbitsa ukadaulo wa konkriti, moyo wotopa umakulitsidwa nthawi zopitilira 3.
- Ntchito yapadziko lonse lapansi
Japan: Pambuyo pa chivomezi cha Hanshin, nyumba yotalikirapo ku Osaka idatengera BF mesh yolimbitsa khoma lometa ubweya, ndipo magwiridwe antchito adakula ndi 40%.
Europe: Konkire yolimba ya BF idagwiritsidwa ntchito poletsa kusefukira kwa madzi ku Venice, Italy, kwa moyo wazaka 50 motsutsana ndi kukokoloka kwa madzi a m'nyanja.
- Milandu ya Engineering
China - Hong Kong-Zhuhai-Macao Bridge: Basalt fiber zinthu zophatikizika zimagwiritsidwa ntchito pa anti-corrosion wosanjikiza wa ma pier ena, kuchepetsa mtengo wokonza ndi 30%.
USA - San Francisco Bay Area Rapid Transit (BART): Nsalu ya BF imagwiritsidwa ntchito polimbitsa mizere ya ngalande, ndipo kukana kwa deformation kumawonjezeka ndi 25%.
4.Challenges ndi Njira Zamtsogolo
- Mavuto omwe alipo
Kusakwanira kwa kulumikizana pakati pa nkhope: mawonekedwe pakati pa fiber ndi konkriti / utomoni amakonda kuvula, zida zatsopano zolumikizirana (mwachitsanzo, zosintha za silane) ziyenera kupangidwa.
Kupanda deta yogwira ntchito kwa nthawi yayitali: makhalidwe okwera a BF kulimbikitsa pansi pa kutentha kwakukulu ndi chilengedwe cha chinyezi chambiri (zoposa zaka 10 za deta akadali opanda ungwiro).
Kufanana kwadongosolo lokhazikika: Mafotokozedwe a uinjiniya wa zida za BF m'maiko osiyanasiyana sanakhazikitsidwe (China yatulutsa GB/T 38143-2019, koma tsatanetsatane wa ntchitoyo iyenera kukonzedwanso).
- Malangizo ofufuza zamtsogolo
Zophatikizika zanzeru: masensa ophatikizika kuti akwaniritse zowunikira zaumoyo (mwachitsanzo, kupsinjika, kudzidziwitsa nokha).
Green kukonzekera luso: kuchepetsa kusungunuka ndi kujambula kutentha (panopa akufunika 1400-1500 ℃), ndi kukhala otsika mpweya ndondomeko.
Multi-scale synergistic reinforcement: kuphatikiza ndi kaboni CHIKWANGWANI ndi chitsulo CHIKWANGWANI kuti apange ma gradient composites.
5.Chidule
Kugwiritsa ntchito kwa basalt fiber mu zomangamanga zasintha kuchoka ku labotale kupita ku engineering, ndipo mawonekedwe ake otsika mtengo komanso okonda zachilengedwe amagwirizana ndi kufunikira kwa nyumba zobiriwira pansi pa cholinga cha "carbon-carbon". M'tsogolomu, ndikofunikira kudutsa kukhathamiritsa kwa mawonekedwe, kutsimikizika kwanthawi yayitali ndi matekinoloje ena ofunikira, ndipo nthawi yomweyo kulimbikitsa kuwongolera kwa mapangidwe ndi ma synergies amakampani, kuti apititse patsogolo ntchito yake yayikulu muzomangamanga zazikulu, zomangamanga zam'madzi, zivomezi ndi kupewa ngozi ndi zochitika zina.
