Imbali yeTungsten

I-Tungsten luhlobo oluthile lwekhemikhali enophawu W kwaye inenombolo ye-athomu engama-74, enokuthiwa yiwolfram. I-Tungsten inzima ukufunyanwa kwindalo njenge-tungsten yasimahla, kwaye ihlala isekwe njengeekhompawundi nezinye izinto.

I-Tungsten ineendidi ezimbini zentsimbi. Ziyi-scheelite kunye ne-wolframite. Igama elithi Wolfram livela kweli lokugqibela. Ngenkulungwane ye-16, abasebenzi-mgodini bachaza iminerali eyayidla ngokuhamba nentsimbi ekrwada. Ngenxa yombala omnyama kunye nenkangeleko enoboya yolu hlobo lweminerali, abasebenzi basezimayini babiza olu hlobo lwentsimbi“wolfram”. Le fossil intsha yaqala ukuchazwa eGeorgius Agricola’Incwadi ethi, De Natura Fossilium ngo-1546. I-Scheelite yafunyanwa ngo-1750 e-Swede. Owokuqala ukuyibiza ngokuba yiTungsten nguAxel Frederik Cronstedt. I-Tungsten yenziwe ngamacandelo amabini, i-tung, ethetha ukuba nzima ngesiSwedish, kunye ne-sten, ethetha ilitye. Kwada kwasekuqaleni kwee-1780s, uJuan José de D´U-Elhuyar wafumanisa ukuba i-wolfram iqulethe izinto ezifanayo kunye ne-scheelite. Kwincwadi kaJuan kunye nomntakwabo, banika le ntsimbi entsha igama elitsha, i-wolfram. Emva koko, izazinzulu ezininzi ziye zahlola le ntsimbi intsha.

Ngo-1847. injineli egama linguRobert Oxland yanika ilungelo elilodwa lomenzi wechiza elinxulumene ne-tungsten., elinyathelo elibalulekileyo elibhekiselele kushishino.

Ngo-1904, iibhalbhu zokukhanya ze-tungsten zokuqala zanikwa ilungelo elilodwa lomenzi, ezathi zatshintsha ngokukhawuleza ezinye iimveliso, njengezibane ze-carbon filament ezingasebenzi kakuhle kwiimarike zokukhanyisa.

Kwi-1920s, ukuvelisa umzobo uyafa ngobunzima obuphezulu, obusondeleyo kwidayimani, abantu baqhubeka bephuhlisa iimpawu ze-samente carbide.

Emva kweMfazwe Yehlabathi II, uqoqosho lufumana ukuchacha okukhulu kunye nokukhula. I-Tungsten carbide iphinda idume ngakumbi njengohlobo lwezixhobo zesixhobo, ezinokuthi zisetyenziswe kwiimeko ezininzi.

Kwi-1944, u-K C Li, uMongameli we-Wah Chang Corporation e-US, wapapasha umfanekiso kwi-Engineering & Mining Journal enesihloko esithi: "Iminyaka eyi-40 yokuKhula komthi weTungsten (1904-1944)"ebonisa uphuhliso olukhawulezayo lwezicelo ezahlukeneyo ze-tungsten kwicandelo lesinyithi kunye nekhemistri.

Ukususela ngoko, ngophuhliso loqoqosho kunye noluntu, abantu baye banemfuno ephezulu yezixhobo zabo kunye nezinto eziphathekayo, ezikhuthaza uhlaziyo oluqhubekayo lweemveliso ze-tungsten carbide. Nangoku, abantu basaphanda kwaye baphuhlise le ntsimbi ukubonelela ngokusebenza kakuhle kunye namava.

Nantsi iZZBETTER. Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
