Uphando malunga neempawu zempembelelo zekhonkrithi yefayibha yebasalt
Izakhiwo zekhonkrithi zinokudibana neempembelelo ezingalindelekanga ngexesha lokusetyenziswa, nto leyo enokubangela umonakalo kwindawo ethile kwisakhiwo, okanye iziphumo ezibi ezifana nokuwa kwesakhiwo, nto leyo ebangela ilahleko ezingenakulungiswa. Ukuze kuqinisekiswe ukhuseleko lwekhonkrithi kwimeko yempembelelo, kubalulekile ukufunda iimpawu zempembelelo zekhonkrithi. Iimpawu zempembelelo ze I-Basalt Fiber ikhonkrithi ifundwe ngovavanyo lwe-SHPB okanye uvavanyo lwe-drop hammer impact.
Ngovavanyo lwempembelelo lufumanise ukuba ukuxutywa kweefayibha zebasalt kunokuphucula ukuqina kwempembelelo yekhonkrithi, ukuqina kwempembelelo kunye nokwanda kobungakanani be imicu ye-basalt ibonise umkhwa wokwanda nokwehla, uphando oluhambelanayo lubonisa ukuba umthamo wokuxuba ifayibha ye-basalt eyi-0.3% kunye ne-0.36% yempembelelo yokusebenza kwekhonkrithi ye-basalt yeyona ilungileyo; xa kuthelekiswa neempawu zomonakalo zesampuli, uphuhliso lweentanda kunye nomonakalo wokugqibela kwimo yokuqhekeka, kufunyenwe ukuba ikhonkrithi ye-basalt fiber yomonakalo weplastiki, oko kukuthi, ukuxutywa kwefayibha ye-basalt kunokwenza ikhonkrithi ifunxe amandla empembelelo ngempumelelo kwaye inefuthe lokuqina kwikhonkrithi. Ukuthelekiswa kweempawu zomonakalo weziqwenga zovavanyo, uphuhliso lweentanda kunye nefom yokugqibela yokuqhekeka komonakalo, kufunyenwe ukuba ikhonkrithi ye-basalt fiber yomonakalo weplastiki, oko kukuthi, ixutywe ne imicu ye-basalt ingenza ikhonkrithi ifunxe amandla empembelelo ngempumelelo, kwaye inefuthe lokuqina kwikhonkrithi. Abaphandi bafunde ukumelana nempembelelo yekhonkrithi yefayibha ye-basalt kunye nomthamo wefayibha ye-basalt (0%, 0.4%, 0.6%, 0.8%) kunye nobude befayibha ye-basalt (6mm kunye ne-18mm) njengezinto eziguquguqukayo. Kufunyenwe ukuba iifayibha ze-basalt zinokuphucula ukuqina kwempembelelo yekhonkrithi, kunye nokuqina kwempembelelo ngokwanda kokuxuba ifayibha kwaye zibe nkulu; ukuxuba ifayibha okufanayo, ubude befayibha yokusebenza kwempembelelo ye-6mm bungcono kunobude bekhonkrithi yefayibha ye-18mm.
Isishwankathelo, ifayibha yebasalt Umxube ungaphucula ukusebenza kwempembelelo yekhonkrithi, kodwa umxube wefayibha ofanelekileyo awufani, ngohlalutyo oluthelekisayo kufumaniseke ukuba le nto ibangelwa yindlela yovavanyo, umlinganiselo wokuxuba ikhonkrithi, ifayibha yebasalt Ukongeza, uphando olukhoyo lugxile kwimpembelelo yefayibha ekusebenzeni kwayo, kwaye kufuneka lwenziwe kwixesha elizayo ukuze kufundwe impembelelo yesantya soxinzelelo kunye nezinye izinto ekusebenzeni kwempembelelo.
