Uhlolojikelele lwe-Basalt Fiber-Reinforced Plaster Mortar

1. Izici Eziyisisekelo ze-Basalt Fiber

I-basalt fiberngokuyinhloko yakhiwe nge-silicon oxide, i-aluminium oxide, ne-iron oxide, enamazinga aphezulu e-silicon oxide ne-aluminium oxide, okukunikeza izinzuzo ezibalulekile ekumelana nokushisa nokushisa. Amakhemikhali ukumelana nokugqwala. Uma kuqhathaniswa nefayibha yengilazi, i-basalt fiber ayinawo ama-oxide ensimbi ayingozi, okuholela ekuzinzeni okungcono kwamakhemikhali nokuqina okuhle kakhulu ezindaweni ezigqwalile njengama-alkali aqinile nama-asidi aqinile.

Amandla aqinile we-basalt fiber ngokuvamile aqala ku-3000 kuya ku-4800 MPa, futhi imodulus yayo enwebekayo iphakathi kuka-80 kuya ku-110 GPa. Lokhu kuyenza ibe namandla kunefiber yengilazi, ene-elongation ephansi ngesikhathi sekhefu, okuthuthukisa ngempumelelo ukumelana nokuqhekeka kwezinto ezisekelwe kusimende.

Ifayibha ye-Basalt ikhombisa ukumelana nezinga lokushisa eliphezulu okuhle kakhulu, enephuzu lokuncibilika elingaphezu kuka-1400°C kanye nezinga lokushisa lesevisi yesikhathi eside elifinyelela ku-700°C, elidlula kude le le-fiber yengilazi. Lokhu kuvumela ukuthi igcine izakhiwo ezinzile ngisho nasezindaweni ezishisa kakhulu.

I-basalt fiber nayo inokumelana ne-alkali ephakeme, ukumelana ne-asidi, nokumelana ne-UV. Ingagcina impilo ende yesevisi ezindaweni ezinzima ezifana nomswakamo, isifutho sikasawoti, nokugqwala kwamakhemikhali, iyenze ifaneleke ikakhulukazi izinto zobunjiniyela njengezendlalelo zokhonkolo lwangaphandle ezivezwa ezindaweni eziyinkimbinkimbi isikhathi eside.

2. I-Crack Resistance Mechanism ye-Fiber-Reinforced Mortar

Umthelela oqinisayo wamafayibha odaka ngokuyinhloko uncike ekusabalaliseni kwawo indawo, ubude, okuqukethwe, nokusebenza kwebhondi ngezinto ezisekelwe kusimende. Ngesikhathi sokuqina kodaka, imifantu emincane ingakheka kalula ngaphakathi ngenxa yezinto ezifana nokuncipha kwevolumu ngenxa yokusabela kwe-hydration kanye nokucindezeleka okushisayo okubangelwa ukushintsha kwezinga lokushisa.

Imicu ingavala izinhlangothi zombili zemifantu emincane, inikeze umphumela wokuvala lapho imifantu iqala ukuqhekeka, ibambezele ngempumelelo ukusakazeka kokuqhekeka futhi ithuthukise ukushuba kwayo konke kanye nokumelana nokuqhekeka. I-basalt fiber inobuso obuqinile, obuhlinzeka ngokuhlangana okuqinile ngokomzimba nokunamathisela usimende. Lapho imithwalo yangaphandle isetshenziselwa udaka, ingxenye yokucindezeleka ingadluliswa ngemicu iye ku-matrix ezungezile, ngaleyo ndlela kuncishiswe ukugxila kokucindezeleka kwendawo futhi kuvimbele ukusakazeka okuqhubekayo kokuqhekeka. Lo mshini wokusabalalisa ukucindezeleka usiza ukuthuthukisa ukuqina okuphelele kanye nokumelana nomthelela wodaka.

Phakathi nenqubo yokuqinisa udaka, imicu ingakha isatshalaliswa ngokungahleliwe Ukuqinisa i-Mesh isakhiwo ngaphakathi kwe-matrix, ukuthuthukisa ukumelana nokuguquguquka kodaka. Lapho ungqimba lwe-plaster lungaphansi kokushintsha kwezinga lokushisa kwangaphandle, ukucindezela kokuncipha kokuqina, noma imithwalo yemishini, le mesh eqinisayo ingamelana ngokuphumelelayo nokuguquguquka ezindaweni zokugxilisa ukucindezeleka, okuholela ekuqineni kokuqhekeka kwezinto ezibonakalayo.
