Metals eliyinjubaqa. ulwazi olusisiseko malunga Tungsten.

izinyithi eliyinjubaqa - isishwankathelo

Ngokubanzi, ukuthetha "izinyithi eliyinjubaqa" kuya kuqondwa ukuba ezi iintsimbi ube iqondo lobushushu enyibilikayo eliphezulu kakhulu, kusenokuba ukufikelela 4000 ° C. Molybdenum, tantalum, Tungsten, ukrweco kunye oluLula Kakhulu - zesinyithi ezisisiseko eliyinjubaqa. Kwakhona olu luhlu kungongezwa, kunye nabanye - chromium, vanadium, osmium, ചിഹ്നം uphawu, yaye zirconium zesinyithi, lobushushu ukunyibilika i ifikelela 2123 ° C.

izinyithi eliyinjubaqa umdla kwiipropati zabo. Ngoko ke, umzekelo, izalathi si zokunikwa molybdenum kunye Tungsten yokuqaqadeka kukwazeke ukusetyenziswa lwezi methali ukuba unyango ubushushu izinto phantsi cleaner. Iimveliso ezenziwe ezithile zesinyithi eliyinjubaqa kufuneka iipropati ezizodwa, umz, bemicu Tungsten wahlala lobushushu olulingana ukuya 3073 ° C.

Kodwa ukungawi zesinyithi eliyinjubaqa ekunokuthiwa ezingeloncedo zazo eziphambili. Iinkcukacha mpilo ngokubonakalayo iphembelela kwiipropati wobushushu zesinyithi eliyinjubaqa. Esi sisizathu ukusetyenziswa zesinyithi kweli qela - kwindawo apho zingakotshwa bodwa ngokupheleleyo emoyeni.

Tungsten - isiseko zesinyithi eliyinjubaqa yokunyibilikisa isinyithi

Tungsten yenye le iintsimbi kakhulu eliyinjubaqa. Ingongoma ukunyibilika Tungsten liphezulu ngaphezu kwabanye, Tungsten - metal enzima, kunokwenzeka ukuba ukuzoba imisonto kakuhle, ukuba nalo weldable ngokugqibeleleyo. Tungsten sisinyithi inqabile, umxholo wayo kwesikhoko ifikelela% 0,0055 kuphela, abakufumana kwi spectrum solar kwaye akakho apha olwandle. Kodwa ngenxa yokuthandwa kwayo ayikho ngaphantsi intsimbi iintsimbi ngaphantsi ezinqabileyo.

Ukusetyenziswa Tungsten

Tungsten sisinyithi esetyenziselwa mveliso ngemisonto filament, ezisetyenziswa kwi izixhobo zokukhanyisa njengento zokufudumeza - in zidle yamaZiko uxhathiso. I eliphezulu Ukushinyana Tungsten ivumela ukusetyenziswa olu njenge counterweight ngenxa projectiles ezahlukeneyo. Njengoko electrode Tungsten kusetyenziswa ngexesha TIG welding. Xa aluminiyamu esiluqilima of Tungsten khabhayithi zisetyenziswa lokufaka.

Tungsten njenge molybdenum, yaye tantalum isetyenziswa umthetho kwi aluminiyamu, asetyenziswa iindawo zobugcisa nuclear isithuba. Ukukwazi ukumelana amaqondo obushushu aphezulu kakhulu - le njongo ephambili apho ezi aluminium zadalwa.
