Tungsten isimbi isingawanzo fanana nesimbi. Kunyungudika kwayo kwakakwirira, kuoma kwakakwirira, kusaita ngura, uye magetsi nemafuta ekufambisa zvakanaka zvinoita kuti ive yakakosha kushanda muindasitiri yechizvinozvino, kudzivirira, uye{1}}mashandisirwo emhando yepamusoro. Saka, ndeapi mashandisirwo chaiwo e tungsten?
1. Alloys
Simbi
Tungsten, nekuda kwekuoma kwayo kwakanyanya uye kuwanda, inovandudza zvakanyanya kusimba, kuoma, uye kupfeka kuramba kwesimbi. Icho chinhu chakakosha alloying chinhu uye chinoshandiswa zvakanyanya mukugadzirwa kwesimbi dzakasiyana. Tungsten yakajairika-ine simbi dzinosanganisira yakakwirira-simbi inomhanya, tungsten simbi, uye tungsten-cobalt magnetic simbi. Izvi zvinonyanya kushandiswa kugadzira maturusi akasiyana siyana, senge madhiri, kucheka kucheka, uye kufa uye mold mold.
Tungsten Carbide{{0}Inobva Cemented Carbide
Tungsten carbide inopfekwa zvakanyanya-inoshingirira uye haibatiki, nekuoma kwedhaimondi, zvichiita kuti ive chinhu chinowanzobatanidzwa mukugadzira simende carbides. Tungsten carbide{{2}based cemented carbide inogona kupatsanurwa muzvikamu zvina: tungsten carbide-cobalt, tungsten carbide{4}}titanium carbide-cobalt, tungsten carbide-titanium carbide-bintalum,8} carbide (8) simbi-yakasungwa simende carbide. Izvi zvinonyanya kushandiswa mukugadzira maturusi ekucheka, maturusi emigodhi, uye waya yekudhirowa inofa.
Pfeka-Resistant Alloys
Tungsten isimbi inorambidzika ine nzvimbo yepamusoro yekunyungudika (kazhinji pamusoro pe1650 degree) uye kuoma kwakanyanya. Naizvozvo, rinowanzo shandiswa kugadzira kupisa-kusingachinji uye kusakara-aroyi asingadziviriri. Semuyenzaniso, alloys etungsten ane chromium, cobalt, uye kabhoni anowanzo shandiswa kugadzira kusakara{5}}zvikamu zvinodzivirirwa zvakaita semavharuvhu nemapombi eturbine muinjini dzendege. Ma alloys e tungsten ane mamwe masimbi anodzikisira (se tantalum, niobium, molybdenum, uye rhenium) anowanzo shandiswa kugadzira-kupisa{8}}kwakakwirira mativi semaroketi nemainjini.
High{{0}Gravity Alloys
Kuwanda nekuoma kweTungsten kunoita kuti ive chinhu chakanakira kugadzira-simba rinokwevera zvinhu pasi. Aya epamusoro-density alloys anogona kuiswa muW-Ni-Fe, W-Ni-Cu, W-Co, W-WC{{9}Cu, uye W{10}Ag series, zvichienderana nekuumbwa kwawo uye mashandisirwo awo. Nekuda kwehukuru hwadzo hwegiravhiti, simba, kukwirisa kwemafuta, kufambiswa kwemagetsi kwakanakisa, uye kugadzirwa kwepamusoro, anowanzo shandiswa mukugadzira zvinhu zvekusangana nazvo zvezvombo, masingi ekupisa, ma switch emapanga, macircuit breaker, uye mamwe maapplication.
II. Electronics
Tungsten inoshandiswa zvakanyanya mumagetsi uye maindasitiri ekupa magetsi nekuda kwekukwira kwayo kwepurasitiki, inononoka kubuda evaporation, yakakwira kunyungudika, uye simba rakasimba rekuburitsa maerekitironi. Semuyenzaniso, tungsten filaments ine kupenya kwepamusoro uye hupenyu hwesevhisi hurefu, zvichiita kuti inowanzoshandiswa mukugadzira filaments yemarambi akasiyana-siyana, semarambi eincandescent uye tungsten{1}}marambi ayodhine. Tungsten filaments inogonawo kushandiswa kugadzira yakananga inopisa cathodes uye magridi emagetsi oscillator machubhu, pamwe nemacathode heaters mune zvakasiyana zviridzwa zvemagetsi.
III. Chemical Industry
Tungsten makomisheni anowanzo shandiswa mukugadzira mamwe marudzi ependi, pigment, ingi, mafuta ekuzora, uye catalysts. Semuenzaniso, sodium tungstate inowanzoshandiswa mukugadzirwa kwesimbi tungsten, tungstic acid uye tungstates, pamwe chete nedhayi, pigments, ingi, electroplating, nezvimwewo; tungstic acid inowanzo shandiswa se modant uye dhayi muindasitiri yemachira, uye sechinhu chinokonzeresa kugadzirwa kwepeturu ye-octane yakakwirira muindasitiri yemakemikari; tungsten disulfide inowanzoshandiswa mune organic synthesis, senge yakasimba lubricant uye catalyst mukugadzirwa kwepeturu yekugadzira; bronze tungsten oxide inoshandiswa mukupenda.
