Kufotokozera Kwachidule

Boron carbide (mankhwala chilinganizo pafupifupi B4C) ndi extremel y zovuta zopangidwa ndi anthu ntchito ngati abrasive ndi refractory ndi ulamuliro ndodo mu nyukiliya reactors, akupanga kubowola, zitsulo ndi num erous mafakitale applications.With a Mohs kuuma pafupifupi 9.497, izo ndi chimodzi mwazinthu zolimba kwambiri zomwe zimadziwika, kumbuyo kwa kiyubiki boron nitride ndi diamondi.Makhalidwe ake apamwamba kwambiri ndi hardness.corrosion resistance ku mankhwala ambiri otakasuka, mphamvu zotentha kwambiri, mphamvu yokoka yochepa kwambiri komanso modulus yapamwamba yotanuka.

ONANI TSOPANO

Mapulogalamu

Boron Carbide ndiyoyenererana ndi ntchito zosiyanasiyana zamafakitale kuphatikiza:

Abrasives kwa lapping ndi akupanga kudula , Anti-oxidant mu carbon-bonded refractory mixes, Zida Nuclear ntchito monga riyakitala ulamuliro ndodo ndi nyutroni kuyamwa kutchinga.

Valani zida monga mphuno zophulitsa, zojambulira mawaya, zitsulo zaufa ndi zida za ceramic kupanga, maupangiri a ulusi.

Amagwiritsidwa ntchito ngati chowonjezera muzowonjezera zoponya mosalekeza chifukwa cha malo ake okwera kwambiri komanso kukhazikika kwamafuta.

Njira Yopanga

Boron Carbide amasungunuka kuchokera ku boric acid ndi mpweya wa ufa mu ng'anjo yamagetsi pansi pa kutentha kwakukulu.Ndi chimodzi mwa zinthu zolimba kwambiri zopangidwa ndi anthu zomwe zimapezeka muzamalonda zomwe zimakhala ndi malo osungunuka otsika kwambiri kuti zilole kuti zikhale zosavuta kupanga mapangidwe ake.Zina mwazinthu zapadera za Boron Carbide ndi izi: kuuma kwakukulu, kusakhazikika kwamankhwala, komanso kuyamwa kwa neutroni, gawo lopingasa.
