China tungsten bala wopanga ndi katundu | Huacheng

kapamwamba tungsten

Short Description:

Tungsten ndi sanali akakhala zitsulo, ndi yofunika njira zitsulo, miyala tungsten kalelo chikudziwika ngati "mwala wolemera '.1781 ndi Swedish sayansi Karl.William.Scheelite anatulukira ndi asidi latsopano elemental, asidi tungstic, anali yotengedwa . mu 1783, tungsten anali yotengedwa tungsten gawo anapeza mwa Msipanishi DE purya. Mu chaka chomwecho, tungsten ufa anali analandira kwa nthawi yoyamba ndi kuchepetsa mpweya wa trioxide tungsten, ndipo amafotokozera za dzina lake. The zili tungsten mu kutumphuka dziko lapansi 0,001%. mitundu makumi awiri mchere tungsten akhala anatulukira. madipoziti Tungsten kawirikawiri kugwirizana ndi ntchito chiphalaphala granitic. Pambuyo yadothi tungsten ndi siliva woyera chonyezimira zitsulo, kusungunuka mfundo ndi mkulu modzipereka kwambiri ...

    Tungsten  bala / Mzere / ndodo

    Tungsten is a non-ferrous metal, is also an important strategic metal, tungsten ore in ancient times is known as “heavy stone”.1781 by Swedish chemist Karl.William.Scheelite was discovered and a new elemental acid, tungstic acid, was extracted. in 1783, tungsten was also extracted from the tungsten deposit discovered by the Spaniard DE purya. In the same year, tungsten powder was obtained for the first time by carbon reduction of tungsten trioxide, and the element was named. The content of tungsten in the earth’s crust is 0.001%. Twenty kinds of tungsten minerals have been discovered. Tungsten deposits are usually associated with the activity of granitic magma. After smelting tungsten is silver white shiny metal, melting point is very high, very hard. Atomic number 74. Steel gray or silver white, high hardness, high melting point, not subject to air erosion at room temperature, the main purpose is to manufacture filament and high-speed cutting alloy steel, superhard die, also used in optical instruments, chemical instruments. Tungsten rod drawn into the wire, can be used as a light bulb, tube and other inside filament.

    Pamene ndegeyo ifika pa chandamale, mwamsanga akutsikira zipolopolo zake. munitions Modern sizili zofanana monga kale, zipolopolo ntchito kukhala mabomba lolemera, monga mivi tomahawk ndi makilogalamu 450 a TNT, mkulu zachiwawa. warplanes Modern Musatenge mabomba kwambiri. Chingasinthe njira yachilendo angakaphe mipherezero. M'malo ntchito ochiritsira zida, agwetsa chitsulo ndodo zopangidwa tungsten, wotchedwa tungsten ndodo. Kuyambira okwera makumi kapena mazana makilomita, ndodo akhoza waponya pa liwiro yopambana, zokwanira kumira ndi wowonongayo kapena ndege chonyamulira, osanenapo galimoto kapena m'ndege. Choncho ntchito ndi digiri yapamwamba molondola, mofulumira liwiro.
