Kedu ihe Boron Carbide (B4C) na-eji?
Maka ike ya:
Ihe ndị dị mkpa nke Boron Carbide, nke nwere mmasị na onye nrụpụta ma ọ bụ onye injinia, bụ ike siri ike na nguzogide abrasive yiri ya.Ọmụmaatụ a na-ahụkarị maka iji akụrụngwa ndị a kacha mma gụnyere: Mkpọchi;Mgbochi mgbochi ballistic nkeonwe na ụgbọ ala;nozzles na-agbawa agbawa;Akwa-nrụgide mmiri jet cutter nozzles;Ikpochapu ma yikwasị mkpuchi na-eguzogide ọgwụ;Ịcha ngwá ọrụ na-anwụ anwụ;Abrasives;Metal matrix composites;Na breeki lining nke ụgbọ ala.
Maka ike ya:
A na-eji boron carbide mee ihe dị ka ihe nchekwa nchekwa iji guzogide mmetụta nke ihe dị nkọ dị ka mgbọ, shrapnel, na akụ.A na-ejikọta ya na ngwakọta ndị ọzọ n'oge nhazi.N'ihi isi ike ya dị elu, ngwa agha B4C na-esiri mgbọ ike ịbanye.Ihe B4C nwere ike ịmịnye ike nke mgbọ wee wepụ ike dị otú ahụ.N'elu ga-akụrisị n'ime obere ihe siri ike ma emechaa.Iji ihe boron carbide, ndị agha, tankị, na ụgbọ elu nwere ike zere mmerụ ahụ dị njọ site na mgbọ.
Maka akụrụngwa ndị ọzọ:
Carbide boron bụ ihe eji achịkwa nke ọma na ụlọ ọrụ ike nuklia maka ike nnabata neutron, ọnụ ala dị ala, yana nnukwu isi mmalite ya.Ọ nwere oke absorption cross-ngalaba.Ikike nke boron carbide ịbanye neutrons na-enweghị ịmepụta radionuclides dị ogologo na-eme ka ọ mara mma dị ka ihe na-adọrọ adọrọ maka radieshon neutron na-ebili na ụlọ ọrụ ike nuklia na site na bọmbụ neutron ndị na-emegide ndị mmadụ.A na-eji Boron Carbide na-echebe, dị ka mkpanaka na-achịkwa n'ime ihe nrụpụta nuklia yana mechiri pellets na ụlọ ọrụ ike nuklia.
