Basalt Fibers Suna Haɓaka juriyar Carbonation na Kanka
I. Mechanism of anti-carbonation action: Multi-scale synergistic ingantawa
1. Tsarin pore da hana fasa
Basalt fibers Hana faɗuwar robobi na farko a cikin kankare (raguwar 30% -50% a faɗi) da toshe hanyoyin watsa CO₂ ta hanyar rarraba raga mai girma uku. Abubuwan hydration mai yawa da aka samar a cikin ƙirar fiber-matrix na iya rage adadin pores masu cutarwa (> 100 nm) daga 18.6% zuwa 12.3%, yana rage haɓakar haɓaka.
2. Gyaran ruwa da kuma Chemical daidaitawa
Fiber surface roughness yana inganta CSH gel heterogeneous nucleation, accelerating da hydration dauki, 28 kwanaki hydration digiri ya karu da 8% -12%. Lokacin da aka haɗa shi da abubuwan ma'adinai (misali, fume silica), tasirin tokar volcanic tare da ƙarancin ƙarancin fiber ya rage jimlar porosity da 40%, kuma adadin pores mara lahani (
II.Aikin injiniya da fa'idojin tattalin arziki
1. Rayuwar hanya ta inganta sosai
Babban aiki Basalt Fiber Kwalta kankare bincike da ɓullo da da Jami'ar Yangzhou, rutting juriya ya karu da 20% -40%, gajiya fatattaka juriya ya karu da sau 2-8, sake zagayowar sake zagayowar daga 3-5 shekaru zuwa 6-8 shekaru, dogon lokaci kula da tsada tanadi ya ragu sosai.
2. Inganta aikin simintin da aka sake fa'ida
Bincike ya nuna cewa lokacin da aka haxa simintin da aka sake yin fa'ida (RAC) tare da 2 kg/m³ basalt fibers, zurfin carbonation yana raguwa da kashi 41% idan aka kwatanta da simintin da aka sake fa'ida, kuma ana samun mafi kyawun juriya na carbonation tare da 50% sake yin fa'ida ga duka.
III. Abubuwan Gabatarwa da Kalubale
1. Binciken haɗin gwiwa da yawa
Bukatar ƙara bincika aikin dogon lokaci a ƙarƙashin haɗin haɗin gishiri-carbonation-chloride, bayanan farko sun nuna cewa adadin carbonation na fiber kankare a ƙarƙashin 0.5 sau na ƙarshe nauyin har yanzu yana da ƙasa da 28%.
2. Haɗin kai na hankali
Shigar da carbonation-hankali fiber fiber da fiber cibiyar sadarwa, real-lokaci tracking na carbonation gaban (daidai ± 0.1 mm), samar da bayanai goyon baya ga m kiyayewa.
Basalt fiber yana ba da mafita mai yawa don juriya na carbonation ta hanyar haɓaka microstructure da haɓaka aikin macro. Tare da haɓaka daidaitattun tsarin da sabbin fasahohi, aikace-aikacensa za a faɗaɗa daga hanyoyi da gadoji zuwa injiniyan ruwa da sauran fagage, haɓaka dorewar abubuwan more rayuwa zuwa sabon zamani.
