Ho ithuta ka ts'ebetso ea ho khomarela ea basalt fiber e matlafalitsoeng ka thepa ea samente e nang le li-tendon tsa BFRP

Lintho tse susumetsang tsa mantlha tsa ts'ebetso ea bonding

1. Fiber volume doping le bolelele

Bophahamo ba doping ea Basalt khoele e khaotsoeng ka nako e khuts'oane e na le phello e kholo ho matla a tlamahano, 'me tlhahlobo e bontša hore tekanyo ea doping ea 0.2% e na le phello e ntle ka ho fetisisa ea ho matlafatsa matla a bonding,' me doping e feteletseng e ka lebisa ho fokotseha ha ts'ebetso ka lebaka la fiber agglomeration.

Bolelele ba fiber (mohlala 6mm le 18mm) bo na le phello e fokolang matleng a bond, empa likhoele tse khutšoane li hasanngoa habonolo ho fokotsa mefokolo ea sefahleho.

2. Sehlopha sa matla sa konkreite e tsosolositsoeng

Ho eketsa matla a konkreite e sebelisitsoeng hape (mohlala, ho tloha ho C30 ho isa ho C40) ho matlafatsa maqhama lipakeng tsa B.Frp Matlafatso le substrate, empa keketseho e lekanyelitsoe, 'me sebopeho se ka hlaseloa habonolo ke brittle peeling ha kereiti ea matla e phahame haholo.

3. Phekolo ea sefahleho le moemeli oa ho kopanya

Ho qhomisa lehlabathe bokahodimo ba BFRP matlafatso ka eketsa roughness le ho ntlafatsa mochine loma matla; Ho eketsa silane coupling agent ho ka ntlafatsa maqhama a lik'hemik'hale pakeng tsa fiber le resin matrix le ho fokotsa ho thella ha sefahleho.

Liteko le mekhoa ea thepa ea ho khomarela

1. Teko ea ho hula bohareng

Bond-slip curve e ile ea ithutoa ka teko ea ho hula, 'me ho ile ha fumanoa hore mokhoa oa ho senya bond e ne e le haholo-holo ho hula ha tendon kapa ho arohana ha konkreite. Keketso ea likhoele tsa basalt e ka liehisa tšenyo e brittle ea konkreite le ho ntlafatsa ductility.

Mefuta e tloaelehileng ea matla a bond ke 6-12 MPa, 'me boleng bo khethehileng bo angoa ke tekanyo ea fiber, bophara ba matlafatso (mohlala, 16 mm) le ts'ebetso ea phekolo ea sebopeho.

2. Mohlala oa kabo ea khatello ea bond

Khatello ea bond e ajoa ka tsela e sa tsitsang ka bolelele ba ho matlafatsa, 'me khatello ea tlhōrō e tsepamisitsoe qetellong ea ho laela. Moetso oa theoretical o hloka ho nahana ka ho hanyetsa katoloso ea crack le phello ea khohlano ea sehokelo sa konkreite e matlafalitsoeng ka faeba.

Melemo ea kopo le linyeoe tsa boenjiniere

1. Ho hanyetsa kutu le ho tšoarella

Matlafatso ea BFRP e boloka ho feta 90% ea matla a eona a bond tikolohong ea khoholeho ea chloride (mohlala, boenjiniere ba leoatleng), bo betere haholo ho feta litšepe le fiberglass e matlafatsang mekoallo.

Taba ka ntlha: Qingdao Cross-Sea Bridge e amohela matlafatso ea BFRP ho nkela matlafatso ea tšepe sebaka, 'me nako ea bophelo ea eona e ekelitsoe ho feta lilemo tse 100.

2. Tshebetso e bobebe le ya Seismic

Boima ba matlafatso ea BFRP ke 1/4 feela ea tšepe, e ka sebelisetsoang ho tiisa maballo a konkreite ho fokotsa boima ba sebopeho ka 20% -30%, 'me ka nako e ts'oanang ho matlafatsa matla a ts'ebeliso ea matla a seismic ka ho phuthela matlafatso.

Mathata a teng le Tataiso ea ho ntlafatsa

1. Ho matlafatsa maqhama a sefahleho

Bothata bo teng: Khokahano pakeng tsa likhoele le matrix ea samente e tloaetse ho peel ka lebaka la khatello ea maikutlo, 'me li-interfacial agents tse fetotsoeng ka nano (mohlala, nano-SiO₂ doped) li hloka ho ntlafatsoa ho matlafatsa bonding ba lik'hemik'hale.

2. Ts'ebetso ea nako e telele le maemo

Khaello ea data ea nako e telele ea creep tlas'a mocheso o phahameng le mongobo o phahameng (mohlala, lilemo tse fetang 10), liteko tse potlakileng tsa botsofali lia hlokahala ho netefatsa; Litlhaloso tsa moralo ha li so tšoane ho pholletsa le linaha, mme leha China e lokolotse maemo a GB/T 38143-2019, litataiso tsa moralo oa lintlha li ntse li hloka ho ntlafatsoa.

3. Moralo oa kopanelo oa mekhahlelo e mengata

Nakong e tlang, re ka hlahloba theknoloji e nyalisitsoeng ea BFRP matlafatso le fiber ea tšepe / carbon fiber ho aha metsoako ea gradient le ho leka-lekanya matla le ductility.

Litaelo tsa Lipatlisiso tsa Kamoso  

1. Tlhokomelo e bohlale le mohlala oa dijithale

Li-sensor tsa fiber optic tse kentsoeng ka har'a li-tendon tsa BFRP, tlhahlobo ea nako ea 'nete ea khatello ea sehokelo sa bond le nts'etsopele ea crack, e kopantsoeng le papiso ea finite element ho ntlafatsa moralo.

2. Mokhoa oa ho lokisetsa khabone e tlaase

Fokotsa mocheso oa ho qhibiliha ha fiber ea basalt le mocheso oa ho hula (hona joale ke 1400-1500 ℃), nts'etsopele ea resin e folisang mocheso o tlase ho fokotsa tšebeliso ea matla.

3. Tšebeliso e nepahetseng ea thepa e sebelisoang hape

Kopanya motsoako o tsosolositsoeng le fiber ea basalt le litšila tsa kaho ho khothalletsa "tsohle-nchafatsoang" tsamaiso ea thepa ea mohaho o motala le ho fokotsa tšebeliso ea lisebelisoa.

Kakaretso

Lipatlisiso mabapi le ts'ebetso ea tlamahano ea thepa ea samente e matlafalitsoeng ka fiber ea basalt le BFRP li-tendon li fihletse liphetho tsa mohato ka mohato, empa ts'ebeliso ea eona e kholo e ntse e hloka ho phunyeletsa litšitiso tsa ho ntlafatsa sefahleho, netefatso ea nako e telele le moralo o hlophisitsoeng. Nakong e tlang, ka mekhoa e mengata ea lintlafatso (mohlala, lisebelisoa tse bohlale, lits'ebetso tsa khabone e tlase), ho lebeletsoe ho hlokomela tsoelo-pele ea theknoloji mafapheng a boenjineri ba maoatle le matlafatso e hanyetsanang le tšisinyeho ea lefatše, le ho thusa ntlafatso ea meaho e tšoarellang.
