Waa maxay Boron Carbide(B4C) loo isticmaalaa?
Adayggiisa awgeed:
Astaamaha muhiimka ah ee Boron Carbide, kuwaas oo danaynaya naqshadeeyaha ama injineerka, waa adkaanta iyo caabbinta xidhashada xoqan ee la xidhiidha.Tusaalooyinka caadiga ah ee isticmaalka ugu wanaagsan ee guryahan waxaa ka mid ah: Qufullada;Dahaarka hubka lidka ku ah baabuurka ee shaqsiga iyo baabuurka;Naaso-qarxinta qashin-qubka;Neef-gooyooyinka jet-biyoodka cadaadiska sarreeya;xoqo oo xidho dahaarka adkaysta;Qalab goynta oo dhinta;Abrasives;Isku-darka matrixka birta;In dahaarka biriiga ee baabuurta.
Adaygeeda:
Carbiide boron waxaa loo isticmaalaa in lagu sameeyo sida Hubka Difaaca si looga hortago saameynta walxaha fiiqan sida rasaasta, jeexjeexyada, iyo gantaalada.Inta badan waxaa lagu daraa waxyaabo kale oo isku dhafan inta lagu jiro habaynta.Sababtoo ah adkeysigeeda sare, hubka B4C way ku adagtahay in ay xabadu dhex gasho.Maaddada B4C waxay nuugi kartaa xoogga rasaasta ka dibna waxay baabi'in kartaa tamartaas.Dusha sare ayaa u burburi doonta qaybo yaryar oo adag hadhow.Isticmaalka qalabka boron carbide, askarta, taangiyada, iyo diyaaradaha waxay ka fogaan karaan dhaawacyo halis ah oo ka yimaada rasaasta.
Guryaha kale:
Boron carbide waa shay kantarool oo si weyn loogu isticmaalo dhirta tamarta nukliyeerka awoodeeda nuugista neutron-ka, qiimo jaban, iyo ilo badan.Waxay leedahay nuugista sare ee qaybta.Awoodda boron carbide si uu u nuugo neutrons iyada oo aan la samayn radionuclides muddada dheer nool waxay ka dhigaysaa mid soo jiidasho leh sida shucaaca neutron-ka ee ka soo baxa dhirta tamarta nukliyeerka iyo bambooyinka neutron-ka ee ka hortagga dadka.Boron Carbide waxaa loo isticmaalaa in lagu gaashaanto, sida usha kantaroolka ee tamarta nukliyeerka iyo sida loo xiro pellets warshad tamarta nukliyeerka ah.
