Tungsten ndi chitsulo chosowa chomwe chimafanana ndi chitsulo. Kusungunuka kwake, kulimba kwake, kusachita dzimbiri bwino, komanso kusinthasintha kwamagetsi ndi kutentha kumapangitsa kuti ikhale yofunikira kwambiri pamakampani amakono, chitetezo, ndi{1}}zaukadaulo wapamwamba. Kotero, kodi tungsten amagwiritsidwa ntchito bwanji?
1. Aloyi
Chitsulo
Tungsten, chifukwa cha kuuma kwake kwakukulu komanso kachulukidwe, imathandizira kwambiri kulimba, kulimba, komanso kukana kwachitsulo. Ndi chinthu chofunika kwambiri cha alloying ndipo chimagwiritsidwa ntchito kwambiri popanga zitsulo zosiyanasiyana. Tungsten wamba-zokhala ndi zitsulo zimaphatikizapo-zitsulo zothamanga kwambiri, chitsulo cha tungsten, ndi tungsten-cobalt magnetic steel. Izi zimagwiritsidwa ntchito popanga zida zosiyanasiyana, monga zobowolera, zodulira mphero, ndi kufa ndi nkhungu.
Tungsten Carbide-Based Cemented Carbide
Tungsten carbide ndi yovala kwambiri-yosamva bwino komanso yosasunthika, ndikulimba koyandikira kwa diamondi, zomwe zimapangitsa kuti ikhale chinthu chodziwika bwino popanga ma carbides opangidwa ndi simenti. Tungsten carbide-based cemented carbide ingagawidwe m'magulu anayi: tungsten carbide-cobalt, tungsten carbide-titanium carbide-cobalt, tungsten carbide-titanium carbide-bintalum,8} ndi carbide {nitalum{8} zitsulo-zomangidwa ndi simenti carbide. Izi zimagwiritsidwa ntchito makamaka popanga zida zodulira, zida zamigodi, ndi kujambula waya kumafa.
Valani-Zophatikiza Zosagwirizana
Tungsten ndi chitsulo chosasunthika chomwe chimakhala ndi malo osungunuka kwambiri (nthawi zambiri amakhala pamwamba pa 1650 digiri) komanso kuuma kwakukulu. Choncho, nthawi zambiri amagwiritsidwa ntchito popanga kutentha-zosamva kutentha ndi kutha-zosakaniza zosamva kutentha. Mwachitsanzo, ma aloyi a tungsten okhala ndi chromium, cobalt, ndi kaboni nthawi zambiri amagwiritsidwa ntchito kupanga-zigawo zosagwira ntchito monga mavavu ndi zonyamulira zama turbine mu injini za ndege. Ma aloyi a tungsten okhala ndi zitsulo zina (monga tantalum, niobium, molybdenum, ndi rhenium) amagwiritsidwa ntchito popanga-kutentha{8}}zigawo zamphamvu monga ma rocket nozzles ndi injini.
High-Ma Aloyi a Gravity
Kuchulukana komanso kulimba kwa Tungsten kumapangitsa kuti ikhale chinthu choyenera kupanga-ma aloyi amphamvu yokoka. Ma aloyi apamwamba kwambiri-akhoza kuikidwa m'magulu a W-Ni{4}}Fe, W-Ni-Cu, W-Co, W-WC{{9}Cu, ndi W{10}}Ag, malingana ndi kapangidwe kawo ndi kagwiritsidwe ntchito. Chifukwa cha mphamvu yokoka, mphamvu, matenthedwe apamwamba kwambiri, magetsi abwino kwambiri, komanso zinthu zabwino kwambiri zogwirira ntchito, zimagwiritsidwa ntchito popanga zida zogwiritsira ntchito zida zankhondo, zozama zamoto, zosinthira mipeni, zowononga dera, ndi zina.
II. Zamagetsi
Tungsten imagwiritsidwa ntchito kwambiri m'mafakitale amagetsi ndi magetsi chifukwa cha pulasitiki yake yayikulu, kutsika pang'onopang'ono kwamadzi, malo osungunuka kwambiri, komanso mphamvu yotulutsa ma elekitironi. Mwachitsanzo, ma tungsten filaments ali ndi mphamvu yowala kwambiri komanso amakhala ndi moyo wautali, zomwe zimawapangitsa kuti azigwiritsidwa ntchito popanga ulusi wamababu osiyanasiyana, monga nyali za incandescent ndi tungsten{1}}nyali za ayodini. Tungsten filaments Angagwiritsidwenso ntchito kupanga mwachindunji mkangano cathodes ndi magidi kwa machubu oscillator pakompyuta, komanso cathode heaters mu zipangizo zosiyanasiyana zamagetsi.
III. Chemical Viwanda
Zinthu za tungsten zimagwiritsidwa ntchito popanga mitundu ina ya utoto, utoto, inki, mafuta opangira mafuta, ndi zopangira. Mwachitsanzo, sodium tungstate nthawi zambiri ntchito kupanga zitsulo tungsten, tungstic acid ndi tungstates, komanso utoto, inki, inki, electroplating, etc.; tungstic acid imagwiritsidwa ntchito ngati mordant ndi utoto m'makampani opanga nsalu, komanso ngati chothandizira kupanga mafuta ochulukirapo-octane m'makampani opanga mankhwala; tungsten disulfide nthawi zambiri amagwiritsidwa ntchito popanga organic synthesis, monga mafuta olimba komanso chothandizira popanga mafuta opangira; Bronze tungsten oxide imagwiritsidwa ntchito pojambula.
