Nhoroondo yeTungsten
Nhoroondo yeTungsten
Tungsten imhando yemakemikari element ine chiratidzo W uye ine nhamba yeatomu ye74, inogona zvakare kunzi wolfram. Tungsten yakaoma kuwanikwa mumasikirwo seyemahara tungsten, uye inogara yakavambwa semakomboni nezvimwe zvinhu.
Tungsten ine marudzi maviri emaori. Iwo scheelite uye wolframite. Zita rokuti Wolfram rinobva kune rekupedzisira. Muzana remakore rechi16, vashandi vomumugodhi vakashuma imwe mineral yaiwanzoperekedzwa nerata. Nekuda kweruvara dema uye kutaridzika kwebvudzi kwemhando iyi yemaminerari, vacheri vakadaidza rudzi urwu rwesimbi“wolfram”. Ichi chisaririra chitsva chakatanga kushumwa muna Georgius Agricola’s bhuku, De Natura Fossilium muna 1546. Scheelite yakawanikwa muna 1750 muSwede. Wekutanga kuidaidza kuti Tungsten ndiAxel Frederik Cronstedt. Tungsten inoumbwa nezvikamu zviviri, tung, zvinoreva kurema muchiSwedish, uye sten, zvinoreva dombo. Kwete kutozosvikira kutanga kwema1780, Juan José de D´Elhuyar akaona kuti wolfram yaive nezvinhu zvakafanana nesheelite. Mukudhindwa kwaJuan nemukoma wake, vanopa iyi simbi itsva zita idzva, wolfram. Pashure pacho, masayendisiti akawanda akaongorora iyi simbi itsva.
Muna 1847 mumwe injiniya anonzi Robert Oxland akapa patent ine chekuita ne tungsten., inova nhanho yakakosha kuenda kumaindasitiri.
Muna 1904, magirobhu ekutanga etungsten akaiswa patent, ayo akakurumidza kutsiva zvimwe zvigadzirwa, semwenje usingashande wecarbon filament pamisika yekuvhenekesa.
Mumakore ekuma1920, kugadzira kudhirowa kunofa nekuomarara kwakanyanya, iri padyo nedhaimani, vanhu vakaramba vachigadzira zvimiro zvecemented carbide.
Mushure meHondo Yenyika II, hupfumi hunowana kupora kukuru uye kukura. Tungsten carbide inowedzera kufarirwa semhando yemidziyo yekushandisa, iyo inogona kuiswa kune akawanda mamiriro.
Muna 1944, K C Li, Mutungamiriri weWah Chang Corporation muU.S., akaburitsa mufananidzo muEngineering & Mining Journal waiti: “Makore makumi mana Kukura kweTungsten Tree (1904-1944)"kuratidza kukurumidza kusimudzira kweakasiyana tungsten application mumunda wesimbi uye chemistry.
Kubva ipapo, nekuvandudzwa kwehupfumi uye nzanga, vanhu vanga vaine chinodikanwa chepamusoro chezvishandiso zvavo uye zvigadzirwa, izvo zvinokurudzira kuenderera mberi kwekuvandudza tungsten carbide zvigadzirwa. Kunyangwe iye zvino, vanhu vachiri kutsvagisa nekugadzira simbi iyi kuti vape zvirinani kushanda zvakanaka uye ruzivo.
Heino ZZBETTER. Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
