Uhlobo olusha lwezinto zokuqinisa ukhonkolo: Imicu ye-basalt enomumo wehinge ongu-12/35/50-millimeter ifinyelela ukusetshenziswa kwezimboni
Emkhakheni wezinto zokuqinisa ukhonkolo, ubuchwepheshe obusha buqala ushintsho olukhulu embonini. Inkampani ehamba phambili yokusungula izinto ezintsha muva nje imemezele ukuthi umkhiqizo wayo oyinhloko - ofana ne-hinge i-basalt fiberenobubanzi obungamamilimitha angu-0.7 kanye nobude obungamamilimitha angu-12/35/50 - ifinyelele ekukhiqizweni kwezimboni. Izosetshenziswa kakhulu ekusebenzeni okuphezulu Izakhiwo Zekhonkrithi, ukuxazulula ngempumelelo inkinga yokuqina kwesikhathi eside.
Ngokungafani nemicu yendabuko enobuso obubushelelezi, lesi sakhiwo esiyingqayizivele esifana ne-hinge se- I-Basalt FiberAma-s angakha amaphuzu amaningi okubambelela komshini ngaphakathi kwe-matrix yekhonkrithi. Lo mklamo uthuthukisa kakhulu ukusebenza kokubopha phakathi kwezintambo kanye ne-matrix, kunciphisa kakhulu ingozi yokuthi izintambo zikhishwe ngaphansi kokucindezeleka. Idatha yokuhlola ikhombisa ukuthi amandla okudonsa ale fibre adlula ama-megapascal angu-1200, kanti i-modulus enwebekayo ifinyelela kuma-gigapascal angu-50. Ingavimbela ngempumelelo ukwakheka nokwanda kwe-microcracks ngesikhathi sepulasitiki kanye nezigaba zokuqina zekhonkrithi.
Ngenxa yokuqina okungokwemvelo kwedwala lentaba-mlilo, lolu hlobo lwefayibha lunokumelana okuhle kakhulu kwe-alkali, okwenza lukwazi ukugcina ukuzinza kokusebenza kwesikhathi eside ezindaweni ezinzima njengobunjiniyela basolwandle, phansi kwezimboni, kanye nengqalasizinda enemijikelezo evamile yokuncibilika nokuqandisa. Ukuhlolwa kokuqala kubonisa ukuthi ukwengeza amakhilogremu angu-3-5 ale fayibha ngemitha eyi-cubic yekhonkrithi kunganciphisa imifantu yokuncibilika ngaphezu kuka-60% uma kuqhathaniswa nokhonkrithi oluvamile, futhi kuphinde kabili ukumelana nokushayisana.
"Lokhu akusikho nje isithasiselo, kodwa kunalokho kuyisisombululo esibanzi sokuthuthukisa esisekelwe ohlelweni," kusho umqondisi we-R&D wase-China Beihai. "Isakhiwo esiyingqayizivele sejometri semicu efana ne-hinge sishintsha ukusatshalaliswa kokucindezeleka ngaphakathi kwekhonkrithi, okwenza onjiniyela bakwazi ukuklama izingxenye ezincane zezingxenye, banciphise inani lemigoqo yokuqinisa, futhi bandise isikhathi sokuphila kwesakhiwo."
Njengamanje, lo mkhiqizo usetshenziswe ngempumelelo kumaphrojekthi abalulekile njengokufakwa kwemigudu eYurophu kanye nokuthuthukiswa kwamachweba eMpumalanga Ephakathi. Amandla awo avelele okumelana nokugqwala kanye nokulawula imifantu aqashelwe kakhulu umphakathi wobunjiniyela. Ngokombono wentuthuko esimeme, ukusetshenziswa kwamandla okukhiqiza kwe imicu ye-basalt iphansi kakhulu kuneyemicu yensimbi noma ye-polymer. Ngaphezu kwalokho, izinto zokusetshenziswa ziningi futhi zivela emvelweni, okuhambisana nomkhuba wokuthuthukiswa kwezakhiwo eziluhlaza.
Ukwethulwa kwalo mkhiqizo kuhambisana nesikhathi esibalulekile sokuthuthukiswa kwezindinganiso zemboni yekhonkrithi yomhlaba wonke. Kuhambisana ngokugcwele nezidingo zezindinganiso zekhonkrithi eziqiniswe ngefayibha zomhlaba wonke, okunikeza onjiniyela ithuluzi eliphumelelayo lokufinyelela amazinga okuqina aphezulu kanye nemigomo yokunciphisa ikhabhoni.
Njengoba izinkinga zokuguga kwengqalasizinda yomhlaba wonke zikhula kanye nezidingo ezikhulayo zentuthuko esimeme, ukwamukelwa kobuchwepheshe bekhonkrithi obuthuthukisiwe obuqiniswe ngefayibha akuseyona nje into entsha yobuchwepheshe; futhi kuyisinqumo esingenakugwenywa sokuthuthukiswa kwemboni. Lokhu kuphumelela kubonisa ukuthi isayensi yezinto zokwakha ikhonkrithi isheshisa ukuthuthuka kwayo ekuhlakanipheni okukhulu, ukuqina okukhulu, kanye nobungane obukhulu bemvelo.
Sizoqhubeka nokuhlola ezicini ezifana nokuklama amafomu e-fiber akhethekile kanye nendlela yokwenza ngcono izixhumanisi zekhonkrithi, ukukhuthaza ukuthuthukiswa kwezindinganiso zemboni kanye nokusungula izinto ezintsha kwezobuchwepheshe, kanye nokuhlinzeka ngezixazululo ezincintisana kakhulu kumaphrojekthi okwakha anamuhla.
