Munda wekushandisa we tungsten

Tungsten inozivikanwawo sewolfram, ikemikari ine chiratidzo cheW uye nhamba yeatomu i74. Isimbi yakasiyana-siyana ine huwandu hwakawanda hwekushanda mune teknolojia yemazuva ano. Tungsten simbi yakaoma uye isingawanzo simbi. Inogona kuwanikwa chete pasi pano mumakemikoro emakemikari. Mazhinji emakemikari ayo emakemikari tungsten oxide uye mazhinji emigodhi tungsten akawanikwa muChina. Kunyanya mumatunhu eHunan neJiangxi. Nekuda kwekunyungudika kwayo kwakakwira, kuomarara kwepamusoro, kuramba kwecorrosion, kunaka kwemagetsi conductivity, uye kudziya kwemafuta, chave chimwe chezvinhu zvakakosha zvinoshanda muindasitiri yemazuva ano. Inoshandiswa zvakanyanya mualloy, zvemagetsi, makemikari, zvekurapa, uye mamwe minda.

1. Mumunda weIndustrial alloys

Powder metallurgy ndiyo nzira yekugadzira tungsten sintered zvigadzirwa. Tungsten poda ndiyo inonyanya kukosha mbishi uye yekutanga tungsten mineral zvigadzirwa. Tungsten hupfu inogadzirwa nekugocha nekudziisa tungsten oxide mumhepo yehydrogen. Kuchena, okisijeni, uye saizi yezvidimbu zvakakosha pakugadzirira tungsten hupfu. Inogona kusanganiswa nezvimwe zvinhu zvehupfu kugadzira akasiyana tungsten alloys.

Tungsten carbide-based cemented carbide:

Tungsten carbide inowanzo shandiswa kusanganisa nedzimwe simbi kuwedzera kushanda kwayo. Iyo simbi yakasanganiswa inosanganisira cobalt, titanium, iron, sirivheri, uye tantalum. Mhedzisiro yacho ndeyekuti tungsten carbide-based cemented carbide ine yakakwirira kupfeka kuramba uye yakakwirira refractory zvivakwa. Izvo zvinonyanya kushandiswa mukugadzira maturusi ekucheka, maturusi emigodhi, waya yekudhirowa inofa, etc. Tungsten carbide-based cemented carbide zvigadzirwa zvinofarirwa kunyange kupfuura simbi isina tsvina nekuda kwekuoma kwavo kunoshamisa uye kuramba kusakara uye kubvaruka. Inogona kushandiswa zvakanyanya mukushambadzira kwekuvaka zvikumbiro, zvemagetsi, kugadzira magiya eindasitiri, radiation shielding zvinhu, uye indasitiri yeaeronautical.

Inodzivirira kupisa uye inodzivirira kupfeka alloy:

Nzvimbo yakanyunguduka ye tungsten ndiyo yepamusoro-soro pakati pesimbi dzese, uye kuoma kwayo ndeyechipiri kune diamond. Saka inowanzoshandiswa kugadzira alloys anodzivirira kupisa uye kupfeka-resistant alloys. Semuyenzaniso, maAlloys e tungsten uye mamwe masimbi anopokana (tantalum, molybdenum, hafnium) anowanzo gadzirwa akasimba-akasimba zvikamu senge nozzles uye injini dzemaroketi. Uye ma alloys e tungsten, chromium, uye kabhoni anowanzoshandiswa kugadzira akasimba-akasimba uye asingapfeki zvikamu, senge mavharuvhu einjini dzendege, mavhiri eturbine, nezvimwe.

2. Mumunda wemakemikari

Tungsten makomisheni anowanzo shandiswa kugadzira mamwe marudzi ependi, ingi, mafuta ekuzora, uye macatalysts. Semuenzaniso, tungsten oxide ine bronze-ruvara inoshandiswa mukupenda, uye calcium kana magnesium tungsten inowanzoshandiswa mu phosphors.

3. Mumunda wemauto

Zvigadzirwa zveTungsten zvakashandiswa kutsiva lead uye zvakapera uranium zvinhu kugadzira mabullet warheads nekuda kwezvisiri-chepfu uye kudzivirira kwezvakatipoteredza zvivakwa, kuitira kuderedza kusvibiswa kwezvinhu zvechiuto kune ecology nharaunda. Pamusoro pezvo, tungsten inogona kuita kuti kurwa kwezvigadzirwa zvemauto kuve kwepamusoro nekuda kwekuoma kwayo kwakasimba uye kunaka kwepamusoro-tembiricha kuramba.

Tungsten inogona kushandiswa kwete chete muminda iri pamusoro asiwo mukufamba, simba reatomu, kuvaka ngarava, indasitiri yemotokari, uye mamwe minda. Kana iwe uchifarira tungsten kana uine chero mibvunzo nezvazvo. Ndapota taura nesu ikozvino.
