Ucwaningo mayelana nokumelana nokugqwala kwekhonkrithi ye-basalt fibre
Ukugqwala kwekhonkrithi kungenye yezimbangela eziyinhloko zokonakala kokuqina kwekhonkrithi, futhi izinkinga zokugqwala kwekhonkrithi zibangela ukulahlekelwa okukhulu kwezomnotho minyaka yonke. Ukuze kuncishiswe ukulahlekelwa kwezomnotho okubangelwa ukugqwala kwekhonkrithi, kubaluleke kakhulu ukutadisha ukumelana nokugqwala kwekhonkrithi. I-Basalt Fiber ukhonkolo.
Njengamanje, ucwaningo ngokumelana nokugqwala kwekhonkrithi ye-basalt fiber luhilela kakhulu ukucwilisa amasampula ekhonkrithi ezixazululweni ezahlukene zokugqwala isikhathi esithile kanye nokuhlaziya ukumelana nokugqwala kwekhonkrithi ye-basalt fiber ngokusebenzisa izivivinyo. Izifundo zokuhlola zithole ukuthi amandla okucindezela kanye namandla okuguquguquka kwe- i-basalt fiber ukwehla kwekhonkrithi njengoba ukuhlushwa kwesisombululo esibolayo kukhuphuka, futhi kwehla nokwanda kwesikhathi sokugqwala esixazululweni esibolayo esinohlu olufanayo. Ukwengezwa kwezintambo ze-basalt kungathuthukisa amandla okucindezela kanye nokuguquguquka kwekhonkrithi endaweni ebolayo. Kodwa-ke, ukwengeza inani elikhulu lezintambo ze-basalt kuzoholela ekunciphiseni kwamandla okucindezela kanye nokuguquguquka kwekhonkrithi. Abanye abacwaningi babeke izibonelo zekhonkrithi ze-basalt fiber esixazululweni se-sodium sulfate izinsuku ezingama-90 futhi bathole ukuthi ukwengezwa kwezintambo ze-basalt kungathuthukisa ngempumelelo ukumelana nokuqhekeka kwekhonkrithi, ngaleyo ndlela kuthuthukise ukumelana kwayo nokugqwala. Ngaphansi kwalezi zimo, ukumelana okuhle kakhulu kokuqhekeka kwatholakala ngokuqukethwe kwevolumu ye-basalt fiber engu-0.1%. Ngesikhathi esifanayo, izibonelo zekhonkrithi ze-basalt fiber zafakwa esixazululweni se-sodium chloride izinsuku ezingama-90, izinsuku eziyi-180, kanye nezinsuku ezingama-270. Ukuqhathanisa kubonise ukuthi ukwengezwa kwe imicu ye-basalt kungavimbela ukuvela kwemifantu kusenesikhathi kukhonkolo, futhi njengoba isikhathi sokugqwala sanda, ukumelana kwemifantu okungcono kakhulu kutholakala nge i-basalt fiber okuqukethwe kwevolumu okungu-0.1%. Ukwengezwa kwenani elifanele lemicu ye-basalt kungathuthukisa ukumelana kwekhonkrithi nokugqwala okuvela ku-sodium sulfate kanye ne-sodium chloride. Ukuhlolwa okucindezelwe kumasampula acwiliswe esixazululweni esigqwalisayo kuthole ukuthi ukwengezwa kwe imicu ye-basalt ingathuthukisa amandla okuguqulwa kwekhonkrithi kanye namandla okuthwala aphezulu, ngomphumela omuhle kakhulu ngokuqukethwe kwevolumu ye-basalt fiber engu-0.1%.
Ngamafuphi, ukwengezwa kwe imicu ye-basalt kungathuthukisa ukumelana nokugqwala kwekhonkrithi. Kodwa-ke, izivivinyo zamanje zigxile kakhulu ezimweni ezigqwalisayo (njengokugqwala kwe-sulfate noma i-chloride), futhi kudingeka ingxoxo eyengeziwe yocwaningo ngezixazululo ezixubile zezinto ezimbili noma ngaphezulu ezigqwalisayo.
