Boron Carbide (B4C) siv rau dab tsi?
Vim nws cov hardness:
Cov khoom tseem ceeb ntawm Boron Carbide, uas yog qhov txaus siab rau tus tsim qauv lossis tus kws ua vaj tse, yog qhov nyuaj thiab qhov cuam tshuam txog kev hnav tsis kam. Piv txwv li ntawm kev siv cov khoom no zoo tshaj plaws suav nrog: Padlocks; Tus kheej thiab lub tsheb tiv thaiv ballistic armor plating; Grit blasting nozzles; High-pressure dej dav hlau cutter nozzles; Kos thiab hnav tsis kam coatings; Cov cuab yeej txiav thiab tuag; Abrasives; Hlau matrix composites; Hauv nres linings ntawm tsheb.
Rau nws cov rigidity:
Boron carbide yog siv los ua cov cuab yeej tiv thaiv kom tiv taus qhov cuam tshuam ntawm cov khoom ntse xws li cov mos txwv, cov khoom tawg, thiab cov foob pob. Nws feem ntau yog ua ke nrog lwm cov khoom sib xyaw thaum lub sijhawm ua tiav. Vim nws muaj zog heev, B4C armor nyuaj rau lub mos txwv nkag mus. Cov khoom siv B4C tuaj yeem nqus lub zog ntawm lub mos txwv thiab tom qab ntawd tshem tawm cov zog ntawd. Qhov saum npoo yuav tawg ua tej daim me me thiab tawv tom qab. Siv cov ntaub ntawv boron carbide, cov tub rog, cov tank, thiab cov dav hlau tuaj yeem zam kev raug mob hnyav los ntawm cov mos txwv.
Rau lwm yam khoom:
Boron carbide yog ib yam khoom siv tswj uas siv dav hauv cov chaw tsim hluav taws xob nuclear vim nws muaj peev xwm nqus neutron, tus nqi qis, thiab muaj ntau qhov chaw. Nws muaj qhov nqus tau zoo. Lub peev xwm ntawm boron carbide los nqus neutrons yam tsis tsim cov radionuclides ntev ua rau nws zoo nkauj ua ib qho khoom nqus rau cov hluav taws xob neutron uas tshwm sim hauv cov chaw tsim hluav taws xob nuclear thiab los ntawm cov foob pob neutron tiv thaiv neeg. Boron Carbide yog siv los tiv thaiv, ua tus pas nrig tswj hauv lub tshuab hluav taws xob nuclear thiab ua cov pellets kaw hauv chaw tsim hluav taws xob nuclear.
