Isishwankathelo seBasalt Fiber-Reinforced Plaster Mortar
1. Iimpawu ezisisiseko zeBasalt Fiber
Ifayibha yeBasaltI-silicon oxide yenziwe ngokuyintloko, i-aluminium oxide, kunye ne-iron oxide, enamanqanaba aphezulu e-silicon oxide kunye ne-aluminium oxide, nto leyo eyinika iingenelo ezibalulekileyo ekumelaneni nobushushu kunye Ikhemikhali ukumelana nokugqwala. Xa kuthelekiswa nefayibha yeglasi, ifayibha yebasalt ayinazo ii-oxide zesinyithi eziyingozi, nto leyo ebangela uzinzo olungcono lweekhemikhali kunye nokuqina okugqwesileyo kwiindawo ezigqwala njenge-alkalis ezinamandla kunye nee-asidi ezinamandla.
Amandla okutsalwa kwefayibha ye-basalt aqhele ukuba phakathi kwe-3000 ukuya kwi-4800 MPa, kwaye i-modulus yayo elastiki iphakathi kwe-80 ukuya kwi-110 GPa. Oku kuyenza ibe namandla kunefayibha yeglasi, inobude obuphantsi xa iqhekeka, nto leyo ephucula ngempumelelo ukumelana nokuqhekeka kwezinto ezisekwe kwisamente.
Ifayibha yeBasalt inamandla okumelana nobushushu obuphezulu, apho iqondo lokunyibilika lidlula i-1400°C kunye nobushushu benkonzo yexesha elide obufikelela kwi-700°C, obudlula kakhulu obo befayibha yeglasi. Oku kuyivumela ukuba igcine iipropati zomzimba ezizinzileyo nakwiindawo ezinobushushu obuphezulu.
I-Basalt fiber ikwanokumelana okuphezulu kwe-alkali, ukumelana ne-asidi, kunye nokumelana ne-UV. Ingagcina ubomi obude benkonzo kwiindawo ezinzima ezifana nokufuma, i-salt spray, kunye nokubola kweekhemikhali, okwenza ukuba ifaneleke ngakumbi kwizixhobo zobunjineli ezifana neengqimba zeplasta zangaphandle ezivezwa kwiindawo ezinzima ixesha elide.
2. Indlela Yokumelana NeeCrack yeFiber-Reinforced Mortar
Impembelelo yokuqinisa iifayibha kwi-mortar ixhomekeke kakhulu kukusasazwa kwazo kwendawo, ubude, umxholo, kunye nokusebenza kokubopha ngezinto ezisekwe kwisamente. Ngexesha lenkqubo yokuqina kwe-mortar, ii-micro-cracks zinokwakheka ngokulula ngaphakathi ngenxa yezinto ezifana nokuncipha komthamo ngenxa yokusabela komswakama kunye noxinzelelo lobushushu olubangelwa kukutshintsha kobushushu.
Iifayibha zinokuvala amacala omabini emiqhekezo emincinci, zibonelele ngesiphumo sokuvala xa imiqhekezo iqalwa, zibambezele ngokufanelekileyo ukusasazwa kwemiqhekezo kwaye ziphucule ukumelana nokuxinana kwezinto. Ifayibha yeBasalt inomphezulu orhabaxa, obonelela ngokudityaniswa okuqinileyo komzimba nentlama yesamente. Xa imithwalo yangaphandle ifakwa kwi-mortar, inxalenye yoxinzelelo ingadluliselwa ngeefayibha ukuya kwi-matrix ejikelezileyo, ngaloo ndlela kunciphisa uxinzelelo lwendawo kwaye kuthintelwe ukwanda kweentanda. Le ndlela yokusabalalisa uxinzelelo inceda ukuphucula ukuqina kunye nokumelana nempembelelo kwe-mortar.
Ngexesha lenkqubo yokuqinisa udaka, imicu inokwenza isasazwe ngokungacwangciswanga Ukuqinisa iMesh ulwakhiwo ngaphakathi kwe-matrix, nto leyo ephucula ukumelana nokuguquguquka kwe-mortar. Xa umaleko we-plaster uphantsi kotshintsho lobushushu bangaphandle, uxinzelelo lokomisa lokuncipha, okanye imithwalo yoomatshini, le mesh yokuqinisa inokumelana ngempumelelo nokuguquguquka kwiindawo zoxinzelelo, nto leyo ekhokelela ekuchaseni okuphezulu kokuqhekeka kwisixhobo.
