Umlando we-Tungsten
Umlando we-Tungsten
I-Tungsten iwuhlobo lwamakhemikhali anophawu W futhi inenombolo ye-athomu engu-74, engabuye ibizwe ngokuthi i-wolfram. I-Tungsten inzima ukutholakala emvelweni njenge-tungsten yamahhala, futhi ihlale isungulwe njengezinhlanganisela nezinye izakhi.
I-Tungsten inezinhlobo ezimbili zamatshe. Ziyi-scheelite ne-wolframite. Igama elithi Wolfram livela kwelakamuva. Ngekhulu le-16, abavukuzi babika nge-mineral evame ukuhambisana ne-tin ore. Ngenxa yombala omnyama nokubukeka okunoboya kwalolu hlobo lwamaminerali, abavukuzi babiza lolu hlobo lwensimbi“wolfram”. Le nsalela entsha yabikwa okokuqala kuGeorgius Agricola’s book, De Natura Fossilium in 1546. I-Scheelite yatholakala ngo-1750 eSwede. Owokuqala ukuyibiza ngokuthi i-Tungsten ngu-Axel Frederik Cronstedt. I-Tungsten yakhiwe izingxenye ezimbili, i-tung, okusho ukuthi iyasinda ngesiSwidi, kanye ne-sten, okusho itshe. Kuze kube sekuqaleni kwawo-1780, uJuan José de D´U-Elhuyar uthole ukuthi i-wolfram iqukethe izakhi ezifanayo ne-scheelite. Encwadini kaJuan nomfowabo, banikeza le nsimbi entsha igama elisha, i-wolfram. Ngemva kwalokho, ososayensi abaningi ngokwengeziwe bahlola le nsimbi entsha.
Ngo-1847. unjiniyela ogama lakhe linguRobert Oxland wanikeza ilungelo lobunikazi elihlobene ne-tungsten., okuyisinyathelo esibalulekile esiya embonini.
Ngo-1904, amalambu okukhanya e-tungsten okuqala anelungelo lobunikazi, ashintsha ngokushesha eminye imikhiqizo, njengezibani ze-carbon filament ezingasebenzi kahle ezimakethe zokukhanyisa.
Ngawo-1920, ukukhiqiza umdwebo uyafa ngobulukhuni obukhulu, obuseduze nedayimane, abantu baqhubeka bethuthukisa izakhiwo ze-cemented carbide.
Ngemva kweMpi Yezwe II, umnotho uthola ukusimama okukhulu nokukhula. I-Tungsten carbide ibuye idume kakhulu njengohlobo lwempahla yamathuluzi, engasetshenziswa ezimeni eziningi.
Ngo-1944, u-K C Li, uMongameli we-Wah Chang Corporation e-US, washicilela isithombe ku-Engineering & Mining Journal enesihloko esithi: "Iminyaka Engu-40 Yokukhula Kwesihlahla Se-Tungsten (1904-1944)"ebonisa ukuthuthuka okusheshayo kwezicelo ezihlukahlukene ze-tungsten emkhakheni we-metallurgy namakhemikhali.
Kusukela ngaleso sikhathi, ngokuthuthukiswa komnotho kanye nomphakathi, abantu baye baba nesidingo esiphezulu samathuluzi abo nezinto zokwakha, ezikhuthaza ukubuyekezwa okuqhubekayo kwemikhiqizo ye-tungsten carbide. Ngisho namanje, abantu basacwaninga futhi bathuthukise le nsimbi ukuze banikeze ukusebenza kahle kanye nolwazi olungcono.
Nansi i-ZZBETTER. Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
