Boron Carbide

Kufotokozera Kwachidule:

Boron Carbide (B4C), yomwe imadziwikanso kuti diamondi yakuda, yokhala ndi kuuma kwa Vickers> 30 GPa, ndi chinthu chachitatu cholimba kwambiri pambuyo pa diamondi ndi kiyubiki boron nitride. Boron carbide ili ndi gawo lalikulu la kuyamwa kwa ma neutroni (mwachitsanzo, chitetezo chabwino ku ma neutroni), kukhazikika kwa radiation ya ionizing ndi mankhwala ambiri. Ndizinthu zoyenera zogwirira ntchito zambiri zapamwamba chifukwa cha kuphatikiza kwake kokongola kwa katundu. Kuuma kwake kwapadera kumapangitsa kuti ikhale ufa wonyezimira wokwanira kupukuta, kupukuta ndi kudula jeti lamadzi lazitsulo ndi zitsulo.

Boron carbide ndi chinthu chofunikira chokhala ndi zopepuka komanso mphamvu zamakina. Zogulitsa za UrbanMines zili ndi chiyero chokwera komanso mitengo yampikisano. Timakhalanso ndi luso lambiri popereka zinthu zosiyanasiyana za B4C. Tikukhulupirira kuti titha kupereka upangiri wothandiza ndikukupatsani kumvetsetsa bwino kwa boron carbide ndi ntchito zake zosiyanasiyana.

Kodi Boron Carbide (B4C) amagwiritsidwa ntchito chiyani?

Kwa kuuma kwake:

Zofunikira za Boron Carbide, zomwe zimakondweretsa wopanga kapena mainjiniya, ndizolimba komanso kusagwirizana ndi abrasive kuvala. Zitsanzo zodziwika bwino pakugwiritsa ntchito bwino zinthuzi ndi izi: Zikhoma; Kuyika zida zankhondo zamunthu ndi galimoto; Ma nozzles otulutsa grit; Ma nozzles odulira madzi othamanga kwambiri; Kukanda ndi kuvala zokutira zosagwira; Kudula zida ndi kufa; Abrasives; Zitsulo masanjidwewo composites; M'mabuleki agalimoto.

Chifukwa cha kuuma kwake:

Boron carbide amagwiritsidwa ntchito kupanga ngati Zida Zoteteza kuti asawononge zinthu zakuthwa monga zipolopolo, ma shrapnel, ndi zoponya. Nthawi zambiri amaphatikizidwa ndi ma composites ena panthawi yokonza. Chifukwa cha kulimba kwake, zida za B4C zimakhala zovuta kuti chipolopolocho chilowe. Zinthu za B4C zimatha kuyamwa mphamvu ya chipolopolocho ndikutaya mphamvu zotere. Pamwamba pake pakanaphwanyika kukhala tinthu ting’onoting’ono ndi tolimba pambuyo pake. Kugwiritsa ntchito zida za boron carbide, asitikali, akasinja, ndi ndege zitha kupewa kuvulala koopsa ndi zipolopolo.

Kwa katundu wina:

Boron carbide ndi chinthu chowongolera chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale amagetsi a nyukiliya chifukwa cha kuthekera kwake koyamwa ma neutroni, mtengo wotsika, komanso gwero lambiri. Ili ndi gawo lalikulu la kuyamwa. Kuthekera kwa boron carbide kuyamwa ma neutroni popanda kupanga ma radionuclides omwe amakhala nthawi yayitali kumapangitsa kuti ikhale yowoneka bwino ngati choyamwa cha nyutroni yotuluka m'mafakitale opangira mphamvu za nyukiliya komanso ku bomba la anti-personnel neutroni. Boron Carbide imagwiritsidwa ntchito poteteza, ngati ndodo yowongolera mu zida za nyukiliya komanso ngati kutseka ma pellets mu fakitale ya nyukiliya.
