Tšusumetso ea Fiberglass ho Khanyetso ea Khoholeho ea Konkreite e Sebelisitsoeng Hape

Tšusumetso ea fiberglass ho haneleng khoholeho ea konkreite e sebelisitsoeng hape (e entsoeng ka li-aggregates tsa konkreite e sebelisitsoeng hape) ke taba e khahlisang haholo saenseng ea thepa le boenjiniere ba sechaba. Leha konkreite e sebelisitsoeng hape e fana ka melemo ea tikoloho le ho sebelisa hape mehloli, litšobotsi tsa eona tsa mechini le ho tšoarella ha eona (mohlala, ho hanyetsa khoholeho ea konkreite) hangata li tlase ho konkreite e tloaelehileng. Fiberglass, e lethepa ea ho matlafatsa, e ka ntlafatsa tshebetso ya konkreite e sebedisitsweng hape ka mekgwa ya mmele le ya dikhemikhale. Tlhahlobo e qaqileng ke ena:

1. Thepa le Mesebetsi eaKhalase ea Fiber

Fiberglass, e leng thepa e seng ea tšepe e sa pheleng, e na le litšobotsi tse latelang:
Matla a ho thaepa a phahameng: E ​​lefella bokgoni bo tlase ba ho thaepa ba konkreite.
Ho hanyetsa tshenyo: E hanela ditlhaselo tsa dikhemikhale (mohlala, di-ion tsa chloride, di-sulfate).
Ho tiisa le ho hanyetsa mapetso**: Ho kopanya mapetso a manyenyane ho diehisa ho ata ha mapetso le ho fokotsa ho kenella ha metsi.

2. Mefokolo ea ho Tšoarella ea Konkreite e Sebelisitsoeng Hape

Lihlopha tse sebelisitsoeng hape tse nang le peista ea samente e setseng e nang le masoba holim'a tsona li lebisa ho:
Sebaka se fokolang sa phetoho ea interfacial (ITZ): Kamano e fokolang pakeng tsa li-aggregate tse sebelisitsoeng hape le peista e ncha ea samente, e leng se etsang hore ho be le litsela tse kenang ka metsing.
Ho se kenelle metsi ho tlase: Dintho tse hoholehang (mohlala, Cl⁻, SO₄²⁻) di kenella habonolo, di baka ho bola ha tshepe kapa tshenyo e kgolo.
Ho se kgone ho hanela serame le ho qhibilihisa: Ho atoloha ha leqhoa masobeng ho baka ho petsoha le ho phatloha.

3. Mekhoa ea Fiberglass ho Ntlafatsa Khanyetso ea Khoholeho ea Moroallo

(1) Litlamorao tsa Tšitiso ea 'Mele
Thibelo ea mapetso: Likhoele tse hasaneng ka mokhoa o ts'oanang li koala mapetso a manyenyane, li thibela kholo ea 'ona le ho fokotsa litsela tsa lintho tse senyang.
Ho teteana ho matlafalitsoeng: Lifaeba li tlatsa masoba, li fokotsa masoba le ho liehisa ho hasana ha lintho tse kotsi.

(2) Ho Tsitsisa Lik'hemik'hale
Fiberglass e hananang le alkali(mohlala, khalase ea AR): Likhoele tse phekotsoeng holim'a metsi li lula li tsitsitse libakeng tse nang le alkali e ngata, li qoba ho senyeha.
Matlafatso ea sebopeho: Ho hokahana ho matla ha fiber-matrix ho fokotsa liphoso ho ITZ, ho fokotsa likotsi tsa khoholeho ea mobu sebakeng seo.

(3) Ho Hanela Mefuta e Ikhethang ea Khoholeho ea Moroallo
Khanyetso ea li-ion tsa chloride: Ho fokotseha ha ho petsoha ho liehisa ho kenella ha Cl⁻, ho liehisa ho bola ha tšepe.
Ho hanyetsa tlhaselo ea sulfate: Ho hola ha mapetso ho thibela tšenyo e bakoang ke ho kristaleha ha sulfate le katoloso.
Ho tšoarella ha leqhoa le ho qhibilihisa: Ho tenyetseha ha faeba ho monya khatello ea maikutlo e bakoang ke ho thehoa ha leqhoa, ho fokotsa ho phatloha ha bokaholimo.

4. Lintlha tsa Bohlokoa tse Susumetsang

Tekanyo ea faeba: Sekhahla se setle ke 0.5%–2% (ka bophahamo); lifaeba tse feteletseng li baka ho bokellana le ho fokotseha ha ho kopana.
Bolelele ba faeba le ho hasana: Lifaeba tse telele (12–24 mm) li ntlafatsa ho tiea empa li hloka kabo e ts'oanang.
Boleng ba di-aggregate tse sebedisitsweng hape: Monyelo o mongata wa metsi kapa seretse se setseng se fokodisa ho kopana ha faeba le matrix.

5. Liphihlelo tsa Lipatlisiso le Liqeto tse Sebetsang

Litlamorao tse ntle: Lithuto tse ngata li bontša hore ho loketsefiberglassHo eketsa ho ntlafatsa ho se kenele metsi haholo, ho hanyetsa chloride, le ho hanyetsa sulfate. Mohlala, fiberglass ea 1% e ka fokotsa li-coefficients tsa ho hasana ha chloride ka 20%–30%.
Tshebetso ya nako e telele: Ho tshwarella ha difaeba dibakeng tsa alkaline ho hloka tlhokomelo. Dikobo tse hanelang alkali kapa difaeba tse kopantsweng (mohlala, ka polypropylene) di ntlafatsa bophelo bo bolelele.
Meeli: Lihlopha tse sebelisitsoeng hape tsa boleng bo tlaase (mohlala, masoba a mangata, litšila) li ka fokotsa melemo ea faeba.

6. Litlhahiso tsa Kopo

Maemo a loketseng: Libaka tsa leoatle, mobu o letsoai, kapa meaho e hlokang konkreite e sebelisoang hape e tšoarellang nako e telele.
Ts'ebetso e ntle ea motsoako: Leka tekanyo ea faeba, karolelano ea phetolo ea aggregate e sebelisitsoeng hape, le tšebelisano-'moho le li-additives (mohlala, silika fume).
Taolo ea boleng: Netefatsa hore faeba e hasana ka ho lekana ho qoba ho kopana ha likhoele nakong ea ho kopanya.

Kakaretso

Fiberglass e ntlafatsa ho hanyetsa khoholeho ea konkreite e sebelisitsoeng hape ka ho tiisa 'mele le ho tsitsisa lik'hemik'hale. Katleho ea eona e itšetlehile ka mofuta oa faeba, tekanyo le boleng ba kakaretso bo sebelisitsoeng hape. Lipatlisiso tsa nakong e tlang li lokela ho shebana le ho tšoarella ha nako e telele le mekhoa ea tlhahiso e theko e tlaase ho nolofatsa lits'ebetso tse kholo tsa boenjiniere.
