Umthelela We-Basalt Fiber Ekusebenzeni Kokhonkolo O Permeable

I-basalt fiber, njengenoveli yezinto ezingaphili, ezisebenza kahle kakhulu, kanye ne-eco-friendly, ithuthukisa kakhulu izakhiwo zemishini, ukuqina, nokusebenza kukakhonkolo ovunyelekayo. Ngezansi ukuhlaziywa kwe-multidimensional kwemithelela yayo namapharamitha wokuthuthukisa:

1. Umthelela Ezimpahleni Zemishini

Amandla Athuthukisiwe Acindezelayo Nama-Flexural

   I-basalt fiber ukuqiniswa kuthuthukisa ngempumelelo amandla okucindezela nokuguquguquka kokhonkolo ovumayo. Ucwaningo lubonisa ukuthi amafayibha akha isakhiwo senethiwekhi esinezinhlangothi ezintathu, eqinisa ukuhlangana phakathi kwama-aggregate nokunamathisela usimende kuyilapho evimbela ukusakazeka kokuqhekeka. Ngokwesibonelo:

Amandla Acindezelayo: Ngemicu engu-12 mm kanye no-24 mm, amandla okucindezela aqala anda bese ehla ngokuqukethwe okuphezulu kwefayibha. Umthamo ophelele ngu-0.1%–0.15% (ngevolumu), namafayibha angama-24 mm athola amandla okucindezela aphezulu angama-24.3 MPa (kumthamo ongu-0.1%).

I-Flexural Strength: Ubude be-fiber bunomphumela ozwakala kakhudlwana emandleni aguquguqukayo. Isibonelo, amafayibha angu-18 mm akhulisa amandla okuguquguquka ngo-66.44% uma kuqhathaniswa nokhonkolo ongenalutho ngenxa yokuxhumana okuhlangene kobuso okuthuthukisiwe okuvela ekuxhumaneni okuhlanganisiwe kwe-fiber-aggregate.

Ukuqina Okuthuthukisiwe kanye Ne-Ductility

"Umphumela wokuvala ibhuloho" we I-Basalt Fibers ithuthukisa ukuqina, iguqule izindlela zokuhluleka ukusuka ku-brittle kuya ku-ductile. Ukuhlaziywa kwe-Microscopic kuveza ukuthi imicu iqinisa uhlaka lwamathambo ngaphakathi kwe-matrix kasimende, ivimbe ngempumelelo ukukhula kokuqhekeka.

Umthelela ku-Permeability

I-Permeability Coefficient eyehlisiwe

Ukufakwa kwe-fiber kuvimbela kancane izimbotshana, kwehlisa ukungena. Isibonelo, ukukhulisa okuqukethwe kwefayibha kusuka ku-0.05% kuya ku-0.2% kancane kancane kunciphisa i-coefficient yokungena, nokho kusahlangabezana nezicaciso (isb., ukufinyeleleka > 1 mm/s ku-20% porosity).

Ukulinganisa i-Porosity ne-Fiber Parameters

Imicu emide (isb., 12 mm → 24 mm) inyusa kancane i-porosity kodwa isehlisa ukungeneka.

Ukuhlanganisa imicu nezixube zamaminerali (isb., umlotha wempukane) kuthuthukisa ukwakheka kwezimbotshana, kunciphisa ukulahleka kokungena ngenkathi kugcinwa amandla.

3. Ukumelana Nesithwathwa Okuthuthukisiwe

Imicu ye-basalt ukuthuthukisa ubuqotho besakhiwo sangaphakathi, kukhulisa kakhulu ukumelana nesithwathwa:

Ngemuva kwemijikelezo engu-100 yokuncibilika kokuqhwaza, ama-specimens aqiniswe ngefayibha abonisa izinga lokulahlekelwa okukhulu okufika ku-0.9% futhi agcine u-62.5% wemodulus eguquguqukayo ehlobene.

I-synergy nomlotha wezimpukane (isb., 6% fly ash + 6 kg/m³ fibers) ifinyelela ukumelana nesithwathwa, njengoba umlotha wezimpukane ucwenga ukwakheka kwezimbotshana kuyilapho imicu icindezela ukuqhekeka kweqhwa.

4. Amapharamitha Wokuthuthukisa Okubalulekile

Ubude Befiber: Amafayibha angu-24 mm anconyiwe ukuze alinganise amandla kanye nokungeneka, nakuba imicu engu-18 mm ihamba phambili ngamandla okuguquguquka.

Ibanga Lomthamo: 0.1%–0.15% ngevolumu (noma 2–6 kg/m³ ngesisindo). Umthamo oweqile ubeka engcupheni i-fiber agglomeration kanye nokuncipha kokusebenza.

I-Synergistic Materials: I-Fly ash (6%–15%) noma i-silica fume (6%–9%) ithuthukisa izici zomshini futhi yehlise ukulahleka kokungena.

5. Izincomo Zohlelo

Izimo: Ilungele abahamba ngezinyawo, amaplaza, nezindawo ezibandayo ezidinga kokubili ukungena namandla.

Ukwakha: Sebenzisa indlela yokuxuba "ehlanganiswe usimende" ukuze uqinisekise ukuhlakazeka kwefayibha efanayo futhi ugweme ukunqwabelana.

Kafushane, i-basalt fiber ithuthukisa i-microstructure nokusebenza kwemishini kokhonkolo ovumayo, kodwa ukulawulwa okuqinile komthamo kanye nemingcele yenqubo kubalulekile ukulinganisa amandla kanye nokungena. Ucwaningo lwesikhathi esizayo kufanele lugxile ekuguqulweni kwendawo yefayibha kanye nokusebenzisana kwezinto eziningi ukuze kunqobe imikhawulo yokusebenza yamanje.
