Mechanism yeBasalt Fiber muKongiri

Concrete, sechinhu chinoputika, inowanzobatanidza fiber kuti iwedzere kushanda kwayo. The mechanism of Basalt Fiber mukongiri zvinonyanya kuratidza mune zvinotevera mativi .

1.Crack Inhibition uye Bridging Effect

Kubva pane iyo fiber spacing theory uye elastic fracture mechanics, basalt fibers kunatsiridza chimiro chemukati chekrete kuburikidza nekubatana kwemuviri-mechanical. Munguva yekuomesa shrinkage uye kunyorova evaporation kwekongiri, mafiber aya anonyatso kuvharira kutangwa uye kupararira kwekutanga-nhanho kuomesa shrinkage microcracks uye kupatsanurwa kutsemuka, nekudaro kudzivirira kumwe kukura kwekutsemuka. Izvi zvinonyanya kuwedzera kupesana nekutsemuka uye kusamira kwekongiri. Uyezve, kana pakatsemuka pakaita mukongiri matrix, basalt fibers bhiriji mativi ese emakatsemuka, inotakura mitoro yekunze uye kudzivirira kamwe kamwe kupatsanuka kwekongiri. Iyi meshini inovandudza kuoma uye kutsemuka kuramba kwekongiri.

2.Kuwedzera kweMechanical Properties

Basalt fibers uye kongiri matrix yakabatana inotakura mitoro yekunze. Muchikamu chekutanga chekurodha, matrix inotakura yakawanda yemutoro. Kamwe kutsemuka kuchikura mumatrix, mafiibhi anoramba achitakura mutoro, achivandudza deformation simba rekongiri muchikamu chepurasitiki. Zvidzidzo zvinoratidza kuti kubatanidza basalt fibers zvakanyanya kunowedzera simba rekumanikidza, kusimba kwesimba, kuomarara, kupatsanura simba rekusimba, uye flexural tensile simba rekongiri.

3.Kuvandudzwa kweDurability

Nekusunga mabhiriji uye nekudzikisa kuumbwa kwawo, basalt fibers inosimudzira kuramba kwechando uye kukanganiswa kwekongiri, ichivandudza zvakanyanya kusimba kwezvivakwa zvekongiri. Pamusoro pezvo, kusanganisirwa kwemafayibha kunonatsiridza kusamira, chando kuramba, uye kuomesa shrinkage zvivakwa, kuwedzera hupenyu hwebasa rekongiri munzvimbo dzakaoma.

4.Microstructural Optimization

Basalt fiberskupindirana nesamende matrix kuburikidza Chemical uye zvisungo zvemuviri, zvichigadzira microstructure yakaoma. Iko kubatanidzwa kwemafiber kunogadzirisa iyo kongiri's microstructure uye inokwidziridza yayo kushushikana-kunetseka maitiro, nekudaro ichiwedzera kuita kwese kwechinyorwa.
