Boron carbide (B4C) siv dab tsi?
Rau nws hardness:
Cov yam ntxwv tseem ceeb ntawm Boron carbide, uas yog qhov txaus siab rau tus tsim qauv lossis engineer, yog hardness thiab cov muaj feem cuam tshuam kev hnav tsis kam. Cov piv txwv raug xws ntawm kev siv tau zoo tshaj plaws ntawm cov khoom muaj xws li: Padlocks; Tus kheej thiab lub tsheb los tiv thaiv kev plees plating; Grit blasting nozzles; Lub Dav Hlau Dej Siab Cutter Nozzles; Kos thiab hnav cov tshuaj tiv thaiv kab mob loj; Tej cuab yeej thiab tuag; Abrasivesives; Hlau Compix Composites; Nyob rau hauv cov kab nres tsheb.
Rau nws txoj kev nyuaj:
Boron Carbide siv los ua cov cuab yeej tiv thaiv kom tiv taus qhov cuam tshuam ntawm cov khoom ntse zoo li cov mos txwv, shrapnel, thiab cuaj luaj. Nws yog feem ntau ua ke nrog lwm cov khoom sib xyaw thaum ua tiav. Vim tias nws lub siab tawv, B4C armor yog qhov nyuaj rau lub mos txwv nkag mus. Cov khoom siv B4C tuaj yeem nqus tau lub zog ntawm cov mos txwv thiab tom qab ntawd dissipates xws li lub zog. Cov saum npoo yuav tawg mus rau hauv me me thiab tawv lus tom qab. Siv Boron Carbide cov ntaub ntawv, cov tub rog, tso tsheb hlau luam, thiab dav hlau yuav zam tsis tau raug mob hnyav los ntawm cov mos txwv.
Rau lwm yam khoom:
Boron Carbide yog qhov kev tswj cov khoom siv ntau yam hauv nuclear fais fab nroj tsuag rau nws cov neutron-abs nqus muaj peev xwm, tus nqi qis, thiab muaj txiaj ntsig tsawg. Nws muaj kev nqus cov khaub lig siab. Lub peev xwm ntawm boron carbide kom nqus cov neutrons tsis muaj kev sib haum xeeb rau neutron hluav taws xob cog thiab los ntawm kev tiv thaiv cov neeg ua haujlwm neutron foob pob. Boron Carbide yog siv los thaiv, raws li kev tswj hwm tus pas nrig hauv nuclear reactor thiab raws li kaw pellets cog hauv lub zog hluav taws xob cog.
