Specification of Concrete Admixture PVA Short Fiber for Thin Layer Cement Based Overlays

Litlhoko tsa Concrete Admixture: PVA Short Fiber bakeng sa Thin Layer-Thehiloeng ka Samente

Tlhahlobo ea Sehlahisoa

PVA short fiber ke fiber ea maiketsetso e sebetsang hantle haholo e entsoeng ka joala ba polyvinyl. E entsoe ka ho khetheha bakeng sa ho sebelisoa ka holim'a moalo o mosesaane oa samente. Likarolo tsena hangata li beoa holim'a lintho tse lokisoang kapa ho sireletsa bokaholimo ba konkreite. Fiber e thusa ho matlafatsa mesifa, laola fracturing, le ho tsoha thata.

Senotlolo se Akarelletsa

Fiber e na le matla a ikhethang a tlamahano le matrices a konkreite. E mamella tlhaselo ea alkali, e hlolang maemong a konkreite. Fiber e 'ngoe le e' ngoe e fokotsehile hore e be boholo bo nepahetseng– hangata mahareng 6 mm le 12 mm– ho etsa bonnete ba hore esita le kabo ka motsoako. Sebaka se ka holimo sa fiber se phekoloa ho ntlafatsa ho khomarela le peista ea konkreite e potolohileng. Sena se lebisa ho ho hanyetsa ha crack ho betere le ho theola ho koeneha.

Sebopeho sa Theknoloji

– Lintho tse bonahalang : Polyvinyl joala (PVA).
– Boholo : 6– 12 mm.
– Diameter : 20– 40 microns.
– Tensile stamina : ≥ 1,200 MPa.
– Modulus e feto-fetohang : ≥ 30 Karolelano ea lintlha tsa mophato.
– Elongation nakong ya khefu : ≤ 8%.
– Ho hanyetsa alkali : E sireletsehile libakeng tse phahameng tsa konkreite.

Melao ea Tšebeliso

Hobaneng U Sebelisa PVA Short Fiber??

Fiber e khuts'oane ea PVA ke fiber ea maiketsetso e kenyellelitsoeng holim'a mekhabiso e entsoeng ka samente. E ntlafatsa haholo ts'ebetso ea lisebelisoa tsa lera le tšesaane. Li-overlay tsena hangata ke tsona feela 10 ho 25 limilimithara tse teteaneng. Ntle le ho matlafatsa, masela a joalo a masesaane a ka robeha kapele tlas'a khatello ea maikutlo kapa a fokotseha. Likhoele tsa PVA li thusa ho laola fractures tsena ho tloha ho nts'etsopele le ho hasana.

Melemo ea Bohlokoa Mererong ea Sebele

Taolo e Ntle ea Arohano: Likhoele tsa PVA li theha marang-rang a teteaneng ka har'a sekoaelo. Marang-rang ana a tšoara sehlahisoa hammoho le ha ho robeha ho honyenyane ho hlaha. Phello ke bokaholimo bo lulang bo sa senyehe nako e telele 'me bo shebahala bo le betere ha nako e ntse e feta.

Boitshoko bo Fetang: Li-overlays tse tšesaane li sebetsana le hora ea lebelo, liphetoho tsa boemo ba leholimo, le meroalo e phetoang. Likhoele tsa PVA li eketsa ho tiea le ho hanyetsa tšusumetso. Sena se fana ka maikutlo a ho fokotseha haholo, spalling, kapa ho apara ka holim'a libaka tsa ho paka likoloi, litselana tsa maoto, le mekato ea borokho.

Boemo bo Bonolo: Ho fapana le mesh ea tšepe kapa likhoele tse kholoanyane, Likhoele tse khutšoane tsa PVA li tsoakana ka ho lekana ka samenteng ntle le ho hohla.
