Waa maxay Broron Carbide (B4C) loo adeegsaday?
Si adag,
Astaamaha ugu muhiimsan ee Boron Carbide, oo xiiseynaya naqshadeeye ama injineerku, waa adkaan iyo caabbinta xirta caabbinta. Tusaalooyinka caadiga ah ee isticmaalka ugu fiican ee guryahaas waxaa ka mid ah: gogoshado; Shaqsi ahaaneed iyo gaari xasaasi ah oo lagula dagaallamayo hubka hubka kudhaca; Giraanyo cufan; Xannaanada jidhka sare ee madaxa-sare ee jidka culayska. Xoq oo xidho jaakad iska caabin ah; Goynta aaladaha oo dhinta; Absaloves; Astaan bir ah oo bir ah; Ee isku xirka gogosha baabuurta.
Wixii adag:
Boron Carbide waxaa loo isticmaalaa in lagu sameeyo awood difaac oo ilaalin ah si ay uga hortagaan saameynta walxaha fiiqan ee sida rasaasta, Shrapnell, iyo gantaalada. Badanaa waxaa lagu daraa kooxo kale inta lagu gudajiro howsha. Sababta oo ah adkaadeynta sare, hubka B4c waa ku adag tahay in xaashida si ay u galaan. Qalabka B4C wuxuu nuugi karaa xoogga rasaasta ka dibna wuu kala bixi karaa tamar noocaas ah. Dusha sare waxay ku dhex burburin doontaa walxaha yaryar oo adag goor dambe. Isticmaalka Qalabka Boron Carbide, askarta, taangiyada, iyo diyaaradaha ayaa ka fogayn kara dhaawacyo halis ah rasaas ka yimaada rasaasta.
Guryaha kale:
Boron Carbide waa mid si aad ah loo isticmaalo xakameynta kontoroolka ee dhirta tamarta nukliyeerka ee awoodeeda neerfaha, qiimaha hooseeya, iyo isha badan. Waxay leedahay qaybta iskutallaab-dhaafka ah ee dheeraadka ah. Awoodda Boron Carbide si loo nuugo yetrons oo aan sameynin radionuclides-ka dheer waxay ka dhigeysaa mid soo jiidasho leh iyadoo ay u nuuxnuuxsato dhirta nutroolka ee ka yimaadda dhirta tamarta nukliyeerka iyo ka hortagga bambaanooyinka neotron bambo. Boron Carbide waxaa loo isticmaalaa gaashaan, sidii usha kontoroolka ee ku-celinta nukliyeerka iyo sidii loo xiray pellet-ka ee warshad tamarta nukliyeerka.
