Patlisiso ka likhoele tsa basalt lits'ebetsong tsa boenjiniere ba sechaba
1.Main application directions
- Lisebelisoa tse matlafatsang tsa konkreite
Fiber Concrete (BFRC): Short-cut Basalt Fibers (6-24mm) li tsoakoa ka konkreite (ho kopanya chelete 0.1% -0.5%), e ka ntlafatsang haholo ho hanyetsa mapheo (fokotsa bophara ba ho phatloha ka 30% -50%), ho hanyetsa tšusumetso (eketseha ka makhetlo a 2-3), le ho tšoarella (ho hanyetsa ha baesekele ho qhibiliha ho eketsehile ka 40%).
Phetoho ea matlafatso ea tšepe: Libakeng tse senyang (mohlala, boenjineri ba metsing), mekoallo e matlafatsang fiber ea basalt (Libaka tsa BFRP) e ka nkela sebaka sa ho matlafatsa tšepe ho qoba mathata a kutu. Ka mohlala, tšebeliso ea bfrp Matlafatso ea likotopo tsa borokho bo tšelang leoatle Qingdao e lebelletsoe ho eketsa nako ea eona ea bophelo ho fihlela lilemo tse fetang 100.
- Matlafatso ea sebopeho le tokiso
Matlafatso ea Lesela la Lesela / Mesh: Lesela la Basalt fiber (matla a tensile ≥2000MPa) le behiloe holim'a maballo le litšiea, tse ka eketsang matla a ho jara mojaro ka 20% -30%. Ka mohlala, ka mor'a hore borokho ba khale ba Sichuan bo matlafatsoe ka lesela la BF, litekanyetso tsa mojaro li ntlafatsoa ho tloha ho Highway-II ho ea ho Sehlopha sa I.
Matlafatso ea litšisinyeho tsa lefatše: likhomphutha tse matlafalitsoeng ka fiber (BFRP) litšiea tsa konkreite tse phuthetsoeng, tse ka ntlafatsang matla le matla a ho senya matla, 'me li loketse mehaho e libakeng tse kotsing ea tšisinyeho ea lefatše.
- Mehaho e mecha e kopantsoeng
Basalt fiber-polymer sandwich panels: e sebelisetsoang marulelo a bobebe le marako a karohano, a nang le matla a mabeli a phahameng le ho kenngoa ha mocheso (thermal conductivity ≤ 0.05 W / mK).
Thepa ea moaho ea khatiso ea 3D: fiber ea basalt-lisebelisoa tse matlafalitsoeng tsa cementitious li ka hlokomela khatiso e rarahaneng ea sebopeho le ho fokotsa litšila tsa kaho.
Melemo ea 2.Technical le Data Core
| Lipontšo Tsa Tshebetso | Basalt fiber | Thepa ea papiso (fiber ea khalase) |
| Matla a tšepe | 3000-4800 MPa | 2000-3500 MPa |
| Ho hanyetsa alkali (pH=13) | Ho boloka matla ≥90% | Fiber ea khalase: ho boloka matla ≤ 50% |
| Melemo ea tikoloho: tšebeliso ea matla a tlhahiso ke 30% feela ea fiber ea khalase, 'me e ka sebelisoa hape ka 100%. | ||
3.Tlhaloso ea Lipatlisiso le Maemo a Tloaelehileng
- Lipatlisiso tsa malapeng
Univesithi ea Tsinghua e ntlafalitse konkreite e fetotsoeng ea basalt fiber-nano-silica e nang le keketseho ea matla a 25% le phokotso ea 60% ea chloride ion.
Univesithi e ka Boroa-bochabela: BF / epoxy resin laminate e khothalelitsoeng e matlafalitse theknoloji ea maballo a konkreite, bophelo ba mokhathala bo atolosoa ka makhetlo a fetang a 3.
- Kopo ea machaba
Japane: Kamora tšisinyeho ea lefats'e ea Hanshin, moaho o phahameng o holimo Osaka o ile oa amohela BF mesh e matlafalitsoeng ka lerako, mme ts'ebetso ea tšisinyeho ea lefatše e ile ea ntlafatsoa ka 40%.
Europe: Konkreite e tiisitsoeng ea BF e ile ea sebelisoa likeiting tsa ho laola likhohola tsa Venice, Italy, ka nako ea bophelo ea lilemo tse 50 khahlanong le khoholeho ea metsi a leoatle.
- Linyeoe tsa Boenjiniere
China - Hong Kong-Zhuhai-Macao Bridge: Basalt fiber lintho tse entsoeng ka motsoako li sebelisoa lera le thibelang kutu ea li-pier tse ling, ho fokotsa litšenyehelo tsa tlhokomelo ka 30%.
USA - San Francisco Bay Area Rapid Transit (BART): Lesela la BF le sebelisoa ho matlafatsa lesela la kotopo, 'me khanyetso ea deformation e eketseha ka 25%.
4.Liqholotso le Litsela tsa Bokamoso
- Mathata a teng
Ts'ebetso e sa lekaneng ea tlamahano ea sefahleho: khokahano lipakeng tsa faeba le konkreite / resin e tloaetse ho hlobola, lisebelisoa tse ncha tsa ho kopanya (mohlala, li-silane modifiers) li hloka ho ntlafatsoa.
Ho haella ha data ea nako e telele ea ts'ebetso: litšoaneleho tsa creep tsa BF reinforcement tlas'a mocheso o phahameng le tikoloho ea mongobo o phahameng (lilemo tse fetang 10 tsa data li ntse li sa phethahala).
Ho lumellana ha tsamaiso e tloaelehileng: litlhaloso tsa moralo oa boenjiniere bakeng sa thepa ea BF linaheng tse sa tšoaneng ha li e-s'o thehoe ka botlalo (China e lokolitse GB/T 38143-2019, empa lintlha tsa kopo li lokela ho hloekisoa).
- Tataiso ea lipatlisiso tsa nako e tlang
Li-composites tse bohlale: li-sensor tse kentsoeng ho fihlela tlhahlobo ea bophelo bo botle (mohlala, khatello, ho itsebahatsa).
Theknoloji ea ho lokisa botala: fokotsa mocheso oa ho qhibiliha le ho hula (hona joale o hloka 1400-1500 ℃), 'me u ntlafatse ts'ebetso ea carbon e tlaase.
Multi-scale synergistic reinforcement: ho kopanya le carbon fiber le tšepe fiber ho aha metsoako ea gradient.
5.Kakaretso
Tšebeliso ea fiber ea basalt ka boenjiniere ba sechaba e tlohile ho laboratoring ho ea ts'ebetsong ea boenjiniere, 'me litšobotsi tsa eona tse bolokang chelete e ngata le tikoloho li lumellana le tlhokahalo ea mehaho e tala tlas'a sepheo sa "khabone e habeli". Nakong e tlang, hoa hlokahala ho phunyeletsa ts'ebeliso ea sebopeho, netefatso ea nako e telele le mahlale a mang a bohlokoa, 'me ka nako e ts'oanang ho khothaletsoa ntlafatso ea litlhaloso tsa moralo le li-synergies tsa indasteri, e le ho potlakisa ts'ebeliso ea eona e kholo meahong e meholo, boenjiniere ba leoatle, ts'isinyeho ea lefatše le thibelo ea likoluoa le maemo a mang.
