Boron hmoov siv rau dab tsi?
Boron hmoov yog dav siv hauv metallurgy, electronics, tshuaj, ceramics, nuclear kev lag luam, tshuaj lom neeg kev lag luam thiab lwm yam kev lag luam.
1. Boron hmoov yog ib hom roj hlau uas muaj siab gravimetric thiab volumetric calorific qhov tseem ceeb, uas tau dav siv nyob rau hauv cov tub rog teb xws li khoom propellants, high-zog explosives, thiab pyrotechnics. Thiab qhov kub ntawm qhov hluav taws kub ntawm boron hmoov yog txo qis heev vim nws cov duab tsis zoo thiab thaj chaw loj tshwj xeeb;
2. Boron hmoov yog siv los ua ib qho khoom siv hlau hauv cov khoom siv hlau tshwj xeeb los tsim cov alloys thiab txhim kho cov khoom siv ntawm cov hlau. Nws tseem tuaj yeem siv los ua cov tungsten xov hlau los yog ua cov khoom hauv cov khoom sib xyaw nrog cov hlau lossis ceramics. Boron feem ntau siv nyob rau hauv cov hom phiaj tshwj xeeb alloys rau harden lwm yam hlau, tshwj xeeb tshaj yog kub-kub brazing alloys.
3. Boron hmoov yog siv los ua deoxidizer hauv oxygen-dawb tooj liab smelting. Ib qho me me ntawm boron hmoov yog ntxiv thaum lub sij hawm cov txheej txheem hlau smelting. Ntawm ib sab, nws yog siv los ua deoxidizer los tiv thaiv cov hlau los ntawm oxidized ntawm qhov kub thiab txias. Boron hmoov yog siv los ua ib qho additive rau magnesia-carbon bricks siv nyob rau hauv kub kub furnaces rau steelmaking;
4. Boron Powders kuj tseem siv tau rau txhua daim ntawv thov uas qhov chaw siab siab xav tau xws li kev kho dej thiab hauv cov roj cell thiab daim ntawv thov hnub ci. Nanoparticles kuj tsim cov chaw siab heev.
5. Boron hmoov kuj yog ib qho tseem ceeb raw khoom rau kev tsim cov high-purity boron halide, thiab lwm yam boron compound raw khoom; Boron hmoov kuj tuaj yeem siv los ua kev pabcuam vuam; Boron hmoov yog siv los ua tus pib rau lub tsheb airbags;
