Kodi Boron Carbide (B4C) imagwiritsidwa ntchito pa chiyani?
Chifukwa cha kuuma kwake:
Makhalidwe ofunikira a Boron Carbide, omwe ndi ofunikira kwa wopanga kapena mainjiniya, ndi kuuma kwake komanso kukana kuvala mopitirira muyeso. Zitsanzo zodziwika bwino za kugwiritsa ntchito bwino magwiritsidwe ntchito awa ndi awa: Ma Padlocks; Ma plating a zida zodzitetezera ku zipolopolo za munthu payekha komanso zamagalimoto; Ma nozzles ophulika ndi grit; Ma nozzles odulira madzi othamanga kwambiri; Zophimba zolimba; Zida zodulira ndi ma dies; Ma Abrasives; Zopangira zitsulo; Mu ma brake linings a magalimoto.
Chifukwa cha kulimba kwake:
Boron carbide imagwiritsidwa ntchito popanga ngati Zida Zoteteza kuti zisagwere ku zinthu zakuthwa monga zipolopolo, zidutswa za mfuti, ndi zida zoponyera mfuti. Nthawi zambiri imaphatikizidwa ndi zinthu zina zophatikizika panthawi yokonza. Chifukwa cha kulimba kwake kwakukulu, zida zankhondo za B4C zimakhala zovuta kuti chipolopolocho chilowe. Zipangizo za B4C zimatha kuyamwa mphamvu ya chipolopolo kenako n’kutulutsa mphamvu zoterozo. Pamwamba pake pakhoza kusweka kukhala tinthu tating’onoting’ono komanso tolimba pambuyo pake. Kugwiritsa ntchito zipangizo za boron carbide, asilikali, matanki, ndi ndege kungapewe kuvulala kwambiri chifukwa cha zipolopolo.
Kwa malo ena:
Boron carbide ndi chinthu chowongolera chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale amagetsi a nyukiliya chifukwa cha mphamvu yake yoyamwa ma neutron, mtengo wake wotsika, komanso gwero lake lochuluka. Ili ndi gawo loyamwa kwambiri. Kuthekera kwa boron carbide kuyamwa ma neutron popanda kupanga ma radionuclide omwe amakhala nthawi yayitali kumapangitsa kuti ikhale yokongola ngati yoyamwa ma radiation a neutron omwe amapezeka m'mafakitale amagetsi a nyukiliya komanso kuchokera ku mabomba a neutron otsutsana ndi antchito. Boron Carbide imagwiritsidwa ntchito kuteteza, ngati ndodo yowongolera mu reactor ya nyukiliya komanso ngati ma pellets otseka mufakitale yamagetsi a nyukiliya.
