Lipatlisiso mabapi le likhoele tsa basalt lits'ebetsong tsa boenjiniere ba sechaba
1. Litaelo tsa kopo e kholo
- Lisebelisoa tsa ho matlafatsa konkreite
Konkreite ea Faeba (BFRC): E khaotsoe ka nako e khuts'oane Fiber ea Basalts (6-24mm) di kopantswe ka konkreite (palo ya ho kopanya 0.1%-0.5%), e leng se ka ntlafatsang haholo kganyetso ya mapetso (ho fokotsa bophara ba mapetso ka 30%-50%), kganyetso ya tshusumetso (e eketseha ka makgetlo a 2-3), le ho tshwarella (kganyetso ya ho tjhesa le ho qhibilihisa potoloho ya ho hatsela e eketsehile ka 40%).
Ho nkeloa sebaka ha matlafatso ea tšepe: Libakeng tse senyang (mohlala, boenjiniere ba likepe), li-bars tsa matlafatso ea fiber ea basalt (Mehala ea BFRP) e ka nkela tšepe e matlafalitsoeng sebaka ho qoba mathata a ho bola. Mohlala, tšebeliso ea bfrp Ho matlafatsoa ha litšiea tsa borokho bo tšelang leoatle Qingdao ho lebelletsoe ho eketsa nako ea bophelo ba bona ho fihlela lilemo tse fetang 100.
- Matlafatso le tokiso ea meaho
Matlafatso ea Lesela la Faeba/Mekhabiso ea Letlooeng: Lesela la faeba la Basalt (matla a ho tensile ≥2000MPa) le khomaretsoa holim'a maballo le litšiea, e leng se ka eketsang bokhoni ba ho jara mojaro ka 20%-30%. Mohlala, ka mor'a hore borokho ba khale ba Sichuan bo matlafatsoe ka lesela la BF, tekanyo ea mojaro e ntlafatsoa ho tloha Highway-II ho ea Sehlopha sa I.
Matlafatso ea litšisinyeho tsa lefatše: metsoako e matlafalitsoeng ke faeba (BFRP) litšiea tsa konkreite tse phuthetsoeng, tse ka ntlafatsang ho ductility le bokgoni ba ho ja matla, 'me li loketse mehaho libakeng tse kotsing ea litšisinyeho tsa lefatše.
- Meaho e mecha e kopaneng
Liphanele tsa sandwich tsa Basalt fiber-polymer: li sebelisoa bakeng sa marulelo a bobebe le mabota a karohano, ka matla a phahameng le ho thibela mocheso (mocheso o tsamaisang mocheso ≤ 0.05 W/mK).
Thepa ea moaho ea khatiso ea 3D: faeba ea basalt-thepa e matlafalitsoeng ea samente e ka etsa khatiso e rarahaneng ea sebopeho le ho fokotsa litšila tsa kaho.
2. Melemo ea Botekgeniki le Lintlha tsa Bohlokoa
| Matšoao a Tshebetso | Faeba ea basalt | Thepa ea papiso (faeba ea khalase) |
| Matla a tšepe | 3000-4800 MPa | 2000-3500 MPa |
| Khanyetso ea alkali (pH=13) | Ho boloka matla ≥90% | Faeba ea khalase: ho boloka matla ≤ 50% |
| Melemo ea tikoloho: tšebeliso ea matla a tlhahiso ke 30% feela ea faeba ea khalase, 'me e ka sebelisoa hape ka 100%. | ||
3. Tswelopele ya Patlisiso le Dinyewe tse Tloaelehileng
- Lipatlisiso tsa lehae
Univesithi ea Tsinghua: e ntlafalitse konkreite e fetotsoeng ea basalt fiber-nano-silica composite ka keketseho ea matla a khatello ea 25% le phokotso ea 60% ea ho kenella ha chloride ion.
Univesithi ea Boroa-bochabela: theknoloji e sisintsweng ea BF/epoxy resin laminate e matlafalitsoeng ea konkreite e matlafalitsoeng, bophelo ba mokhathala bo atolositsoe ka makhetlo a fetang 3.
- Kopo ea machaba
Japane: Kamora tšisinyeho ea lefatše ea Hanshin, moaho o molelele Osaka o ile oa sebelisa lebota la BF le matlafalitsoeng ka letlooa, 'me ts'ebetso ea litšisinyeho tsa lefatše e ile ea ntlafala ka 40%.
Europe: Konkreite e matlafalitsoeng ea BF e sebelisitsoe lihekeng tsa taolo ea likhohola Venice, Italy, ka nako ea bophelo ba lilemo tse 50 khahlanong le khoholeho ea metsi a leoatle.
- Linyeoe tsa Boenjiniere
Borokho ba Chaena - Hong Kong-Zhuhai-Macao: Faeba ea basalt thepa e kopaneng e sebelisoa lera le thibelang ho bola la lipier tse ling, e leng se fokotsang litšenyehelo tsa tlhokomelo ka 30%.
USA - Sepalangoang se Potlakileng sa Sebaka sa San Francisco Bay (BART): Lesela la BF le sebelisoa ho matlafatsa lesela la kotopo, 'me khanyetso ea ho fetoha ha sebopeho e eketseha ka 25%.
4. Liphephetso le Litaelo tsa Nakong e Tlang
- Mathata a teng
Tshebetso e sa lekaneng ya ho kopanya difacial: kgokelo pakeng tsa faeba le konkreite/resin e sekametse ho hloboleng, di-coupling agent tse ntjha (mohlala, di-silane modifiers) di hloka ho ntshetswa pele.
Ho hloka data ea ts'ebetso ea nako e telele: litšobotsi tsa ho thekesela ha matlafatso ea BF tlas'a mocheso o phahameng le tikoloho e mongobo o phahameng (lilemo tse fetang 10 tsa data li ntse li sa phethahala).
Ho tšoana ha sistimi e tloaelehileng: litlhaloso tsa moralo oa boenjiniere bakeng sa thepa ea BF linaheng tse fapaneng ha li so thehoe ka botlalo (Chaena e lokollotse GB/T 38143-2019, empa lintlha tsa kopo li lokela ho ntlafatsoa).
- Tataiso ea lipatlisiso tsa nakong e tlang
Metswako e bohlale ea faeba: li-sensor tse kentsoeng ho fihlela tlhokomelo ea bophelo bo botle ba sebopeho (mohlala, khatello, ho itlhokomela ka mapetsong).
Theknoloji ea ho lokisa e tala: fokotsa mocheso oa ho qhibiliha le ho hula (hajoale ho hlokahala 1400-1500℃), 'me u ntlafatse ts'ebetso ea khabone e tlase.
Matlafatso ea tšebelisano-'moho ka tekanyo e mengata: ho kopanya le fiber ea khabone le fiber ea tšepe ho haha li-composites tsa gradient.
5. Kakaretso
Tšebeliso ea faeba ea basalt Boenjiniere ba kaho bo fetohile ho tloha laboratoring ho ea ho mokhoa oa boenjiniere, 'me litšobotsi tsa eona tse theko e tlaase le tse sireletsang tikoloho li lumellana le tlhoko ea mehaho e tala tlas'a sepheo sa "khabone e habeli". Nakong e tlang, ho hlokahala ho phunyeletsa ntlafatso ea sebopeho, netefatso ea ho tšoarella ha nako e telele le mahlale a mang a bohlokoa, 'me ka nako e ts'oanang ho khothaletsoa ntlafatso ea litlhaloso tsa moralo le tšebelisano-'moho ea ketane ea indasteri, e le ho potlakisa ts'ebeliso ea eona e kholo meralong ea motheo e meholo, boenjiniere ba likepe, tšisinyeho ea lefatše le thibelo ea likoluoa le maemo a mang.
