Ucwaningo ngezakhiwo zomthelela zikakhonkolo we-basalt fiber
Izakhiwo zikakhonkolo zingase zibe nomthelela wengozi phakathi nokusetshenziswa, okungase kubangele ukulimala kwendawo esakhiweni, noma imiphumela emibi njengokubhidlika kwesakhiwo, okuletha ukulahlekelwa okungenakulungiseka. Ukuze kuqinisekiswe ukuphepha kokhonkolo esimweni somthelela, kubalulekile ukutadisha izakhiwo ezithinta ukhonkolo. Izici zomthelela we I-Basalt Fiber ukhonkolo uhlolwe ukuhlolwa kwe-SHPB noma ukuhlolwa komthelela wesando.
Ngokuhlolwa komthelela kutholwe ukuthi ukuxutshwa kwemicu ye-basalt kungathuthukisa ukuqina komthelela kakhonkolo, ukuqina komthelela nokwanda kwenani le-basalt. imicu ye-basalt wabonisa umkhuba wokwanda bese wehla, ucwaningo oluhlobene lubonisa ukuthi umthamo we-basalt fiber mixing 0.3% kanye no-0.36% we-basalt fiber ukhonkolo womthelela ongcono kakhulu; uma kuqhathaniswa nezici zokulimala zesampula, ukuthuthukiswa kokuqhekeka kanye nokulimala kokugcina ngendlela yokuphuka, kutholakale ukuthi ikhonkrithi ye-basalt fiber yokulimala kwepulasitiki, okungukuthi, ukuxuba i-basalt fiber kungenza ikhonkrithi ibambe ngempumelelo amandla omthelela futhi ibe nomthelela oqinile kukhonkolo. Ukuqhathaniswa kwezimpawu zokulimala kwezingcezu zokuhlola, ukuthuthukiswa kokuqhekeka kanye nohlobo lokugcina lokuphuka komonakalo, kutholwe ukuthi ukhonkolo we-basalt fiber ngomonakalo wepulasitiki, okungukuthi, uxutshwe imicu ye-basalt ingenza ikhonkrithi imunce ngempumelelo amandla omthelela, futhi ibe nomthelela oqinile kukhonkolo. Abacwaningi bafunde ukumelana nomthelela kakhonkolo we-basalt fiber ngevolumu ye-basalt fiber (0%, 0.4%, 0.6%, 0.8%) kanye nobude be-basalt fiber (6mm kanye ne-18mm) njengokuguquguqukayo. Kutholakale ukuthi izintambo ze-basalt zingathuthukisa ukuqina komthelela wekhonkrithi, kanye nokuqina komthelela ngokunyuka kokuxuba i-fiber futhi ibe mkhulu; ukuxuba okufanayo kwefayibha, ubude befayibha bokusebenza komthelela ongu-6mm bungcono kunobude bukakhonkolo wefayibha engu-18mm.
Ngokufigqiwe, i-basalt fiber i-admixture ingathuthukisa ukusebenza komthelela wekhonkrithi, kodwa i-fiber admixture elungile ayifani, ngokuhlaziywa okuqhathanisayo kwathola ukuthi lesi simo sibangelwa indlela yokuhlola, isilinganiso sokuxuba ukhonkolo, i-basalt fiber ukuxubana nezinye izici, ubunye bezinto ezifanele kufanele buqiniswe ekuhlolweni okuzayo. Ngaphezu kwalokho, ucwaningo olukhona lugxile emphumeleni womthamo wefayibha ekusebenzeni kwawo komthelela, futhi kufanele lwenziwe esikhathini esizayo ukuze kufundwe umthelela wesilinganiso sobunzima nezinye izici ekusebenzeni komthelela.
