Thuto mabapi le ts'ebetso ea ho khomarela ea thepa ea samente e matlafalitsoeng ea basalt fiber e nang le li-tendon tsa BFRP

Mabaka a mantlha a susumetsang ts'ebetso ea tlamahano

1. Ho sebelisa tekanyo ea fiber le bolelele ba eona

Ho sebelisa lithethefatsi tse ngata haholo Basalt khoele e kgutshwane e na le phello e kgolo matleng a ho kopanya, mme teko e bontsha hore ho sebedisa doping ya bophahamo ba 0.2% ho na le phello e ntle ka ho fetisisa matleng a ho kopanya, mme ho sebedisa doping e feteletseng ho ka lebisa ho theoheng ha tshebetso ka lebaka la ho kopana ha faeba.

Bolelele ba faeba (mohlala, 6mm le 18mm) bo na le phello e nyane matla a tlamo, empa difaeba tse kgutshwane di hasanngwa habonolo ho fokotsa diphoso tsa interfacial.

2. Sehlopha sa matla sa konkreite e sebelisitsoeng hape

Ho eketsa matla a konkreite e sebedisitsweng hape (mohlala, ho tloha ho C30 ho isa ho C40) ho eketsa matla a tlamo pakeng tsa BMatlafatso ea Frp le substrate, empa keketseho e lekanyelitsoe, 'me sebopeho se kotsing ea ho peeling ha matla a le holimo haholo.

3. Kalafo ea sebopeho le moemeli oa ho kopanya

Ho qhaqha lehlabathe holim'a BFRP Matlafatso e ka eketsa ho rarahana le ho ntlafatsa matla a ho loma a mechini; ho eketsa sesebelisoa sa ho kopanya sa silane ho ka ntlafatsa kamano ea lik'hemik'hale pakeng tsa faeba le resin matrix le ho fokotsa ho thella ha interfacial.

Liteko le mekhoa ea thepa ea sekhomaretsi

1. Teko ea ho ntša e bohareng

Mokoloko oa ho thella ha bond o ithutiloe ka teko ea ho hula, 'me ho fumanoe hore mokhoa oa tšenyo ea bond e ne e le haholo-holo ho hula ha tendon kapa ho petsoha ha konkreite. likhoele tsa basalt e ka diehisa tshenyo e robehang ya konkreite le ho ntlafatsa ho ductility.

Matla a tloaelehileng a tlamo ke 6-12 MPa, 'me boleng bo itseng bo angoa ke tekanyo ea faeba, bophara ba matlafatso (mohlala, 16 mm) le mokhoa oa kalafo ea sebopeho.

2. Mohlala oa kabo ea khatello ea libonto

Kgatelelo ya tlamo e arolwa ka tsela e sa tsamaellaneng le bolelele ba matlafatso, mme kgatelelo ya tlhoro e kgobokantswe qetellong ya mojaro. Mohlala wa thuto o hloka ho nahana ka kganyetso ya katoloso ya mapetso le phello ya kgohlano ya sebopeho sa konkreite e matlafaditsweng ka faeba.

Melemo ea kopo le linyeoe tsa boenjiniere

1. Ho hanyetsa ts'enyeho le ho tšoarella

Matlafatso ea BFRP e boloka matla a eona a tlamo a fetang 90% libakeng tsa khoholeho ea chloride ion (mohlala, boenjiniere ba likepe), e leng se betere haholo ho feta li-bars tsa tšepe le fiberglass.

Mohlala: Borokho ba Qingdao Cross-Sea bo sebelisa matlafatso a BFRP ho nkela matlafatso a tšepe sebaka, 'me nako ea bophelo ba bona e ekelitsoe ho feta lilemo tse 100.

2. Tshebetso e bobebe le ea Tšisinyeho ea Lefatše

Botenya ba matlafatso ea BFRP ke karolo ea 1/4 feela ea tšepe, e ka sebelisoang ho matlafatsa mabala a konkreite ho fokotsa boima ba sebopeho ka 20%-30%, 'me ka nako e ts'oanang ho ntlafatsa bokhoni ba ts'ebeliso ea matla a tšisinyeho ea lefatše ka ho phuthela matlafatso.

Liphephetso tse teng le Tataiso ea Ntlafatso

1. Ho matlafatsa maqhama a sefahleho

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

2. Tshebetso ya nako e telele le ho etswa ha maemo

Ho hloka tlhahisoleseding ya ho thekesela ha nako e telele tlasa mocheso o phahameng le mongobo o phahameng (mohlala, dilemo tse fetang 10), ho hlokahala diteko tse potlakileng tsa botsofali ho netefatsa; ditlhaloso tsa moralo ha di so tshwane ho pholletsa le dinaha, mme leha China e lokollotse maemo a GB/T 38143-2019, ditataiso tsa moralo wa dintlha di ntse di hloka ho ntlafatswa.

3. Moralo oa tšebelisano-'moho oa maemo a mangata

Nakong e tlang, re ka hlahloba theknoloji e kopaneng ea BFRP matlafatso le faeba ya tshepe/khabone ho aha metsoako ya gradient le ho leka-lekanya matla le ductility.

Litaelo tsa Lipatlisiso tsa Nakong e Tlang  

1. Tlhokomelo e bohlale le mohlala oa dijithale

Li-sensor tsa fiber optic tse kentsoeng ka har'a li-tendon tsa BFRP, tlhokomelo ea nako ea sebele ea khatello ea sebopeho sa bond le nts'etsopele ea mapetso, hammoho le ketsiso ea likarolo tse lekanyelitsoeng ho ntlafatsa moralo.

2. Mokhoa oa ho lokisa khabone e tlase

Fokotsa ho qhibiliha ha faeba ea basalt le ho hula mocheso (oo hona joale o leng 1400-1500 ℃), nts'etsopele ea resin e phekolang mocheso o tlase ho fokotsa tšebeliso ea matla.

3. Tšebeliso e sebetsang hantle ea thepa e sebelisitsoeng hape

Kopanya aggregate e sebelisitsoeng hape le faeba ya basalt le matlakala a kaho ho kgothaletsa sistimi ya thepa ya kaho e tala e "ntjhafatswang ka botlalo" le ho fokotsa tshebediso ya mehlodi.

Kakaretso

Phuputso mabapi le ts'ebetso ea ho kopanya thepa ea samente e matlafalitsoeng ke fiber ea basalt le BFRP Tendons e fihletse liphetho mohato ka mohato, empa ts'ebeliso ea eona e kholo e ntse e hloka ho phunyeletsa litšitiso tsa ntlafatso ea interfacial, netefatso ea ho tšoarella ha nako e telele le moralo o tloaelehileng. Nakong e tlang, ka boqapi bo fapaneng ba mafapha a mangata (mohlala, thepa e bohlale, lits'ebetso tse nang le khabone e tlase), ho lebelletsoe hore e tla fihlela katleho ea theknoloji masimong a boenjiniere ba likepe le matlafatso e hanelang litšisinyeho tsa lefatše, le ho thusa nts'etsopele ea meaho e tsitsitseng.
