Ucwaningo nge-Corrosion Resistance ye-Basalt Fiber Concrete
Ukugqwala kukakhonkolo kungenye yezimbangela ezinkulu zokuwohloka kokuqina kokhonkolo, futhi izindaba zokugqwala okukhonkolo zidala ukulahlekelwa okukhulu kwezomnotho minyaka yonke. Ukunciphisa ukulahlekelwa kwezomnotho okubangelwa ukugqwala kukakhonkolo, kubaluleke kakhulu ukufunda ukumelana nokugqwala kwe-corrosion. I-Basalt Fiber ukhonkolo.
Njengamanje, ucwaningo mayelana nokumelana nokugqwala kukakhonkolo we-basalt fiber ikakhulukazi kuhilela ukucwiliswa kwezibonelo zikakhonkolo ezixazululweni ezihlukene zokugqwala isikhathi esithile kanye nokuhlaziya ukumelana nokugqwala kukakhonkolo we-basalt fiber ngokusebenzisa izivivinyo. Izifundo zokuhlola zithole ukuthi amandla okucindezela kanye namandla okuguquguquka kwe i-basalt fiber ukwehla okukhonkolo njengoba ukugcwala kwesixazululo esigqwalayo kukhuphuka, futhi ziphinde zehle ngokwanda kwesikhathi sokugqwala esixazululweni esigqwalayo sokugxila okufanayo. Ukwengezwa kwemicu ye-basalt kungathuthukisa amandla okhonkolo acindezelayo futhi aguquguqukayo endaweni ebolayo. Kodwa-ke, ukwengeza inani eliningi lemicu ye-basalt kuzoholela ekwehleni kwamandla kakhonkolo acindezelayo futhi aguquguqukayo. Abanye abacwaningi babeke izibonelo zikakhonkolo ze-basalt fiber esixazululweni se-sodium sulfate izinsuku ezingu-90 futhi bathola ukuthi ukungezwa kwemicu ye-basalt kungathuthukisa ngempumelelo ukumelana nokuqhekeka kukakhonkolo, ngaleyo ndlela kuthuthukise ukumelana nokugqwala. Ngaphansi kwalezi zimo, ukumelana nokuqhekeka okungcono kakhulu kwafinyelelwa ngokuqukethwe kwevolumu ye-basalt fiber engu-0.1%. Ngesikhathi esifanayo, izibonelo zikakhonkolo ze-basalt fibre zafakwa kusisombululo se-sodium chloride izinsuku ezingu-90, izinsuku ezingu-180, nezinsuku ezingu-270. Ukuqhathanisa kwabonisa ukuthi ukungezwa kwe imicu ye-basalt ingavimbela ukuthuthukiswa kokuqhekeka kokuqala kukakhonkolo, futhi njengoba isikhathi sokugqwala sikhula, ukumelana nokuqhekeka okungcono kakhulu kufinyelelwa nge i-basalt fiber okuqukethwe kwevolumu ka-0.1%. Ukwengezwa kwenani elifanele lemicu ye-basalt kungathuthukisa ukumelana kukakhonkolo nokugqwala kusuka ku-sodium sulfate ne-sodium chloride. Ukuhlolwa okucindezelayo kuma-specimens afakwe kwisixazululo esonakalisayo kutholwe ukuthi ukungezwa kwe imicu ye-basalt ingathuthukisa amandla kakhonkolo wokuguga kanye namandla okuthwala ekugcineni, ibe nomphumela omuhle kakhulu wokuqukethwe kwevolumu ye-basalt fiber engu-0.1%.
Kafushane, ukungezwa kwe imicu ye-basalt ingathuthukisa ukumelana nokugqwala kukakhonkolo. Kodwa-ke, ukuhlola kwamanje ngokuyinhloko kugxile ezimeni zokugqwala okukodwa (njenge-sulfate noma ukugqwala kwe-chloride), futhi ingxoxo eyengeziwe iyadingeka ukuze kwenziwe ucwaningo lwezixazululo ezixubile zezinto ezimbili noma ngaphezulu ezonakalisayo.
