Tungsten molybdenum crucible W crucible Mo crucible
Kuwonetsa Zamalonda
Monga chitsulo chopanda chitsulo, tungsten ali ndi mphamvu zambiri komanso kuuma.Chifukwa cha 2.Main Mbali iyi, tungsten carbide yokhala ndi kuuma kwakukulu ndi kukana kwamphamvu kuvala kwagwiritsidwa ntchito podula zida ndi zida zamigodi pamlingo waukulu.
Tungsten ndiye chitsulo chosasunthika chokhala ndi malo osungunuka kwambiri.Zitsulo zonse zomwe zimasungunuka kwambiri kuposa 1650 ℃ ndi malo ena osungunuka komanso malo osungunuka a zirconium (1852 ℃) amatchedwa zitsulo zokana.Zitsulo zodziyimira pawokha ndi tungsten, tantalum, molybdenum, niobium, hafnium, chromium, vanadium, zirconium, ndi titaniyamu.Monga chitsulo chosakanizika, mwayi wofunikira kwambiri wa tungsten ndikuti uli ndi mphamvu yabwino yotentha komanso kukana kwa dzimbiri kuzitsulo zosungunuka za alkali ndi nthunzi.Zimangowoneka pamwamba pa 1000 ℃.Molybdenum ndi tungsten ali ndi zinthu zofanana kwambiri, malo otentha odziwika bwino komanso machulukidwe amagetsi, kachulukidwe kakang'ono kowonjezera kutentha, komanso kosavuta kukonza kuposa tungsten.
Kutentha kwachitsulo cha molybdenum [135 Watts / (m · kutseguka)] kumagwira ntchito bwino ndi kutentha kwapadera [0.276 kJ / (kg · kutseguka)], kupanga chisankho chachilengedwe motsutsana ndi kutentha kwa kutentha ndi kutopa kwamafuta.Malo ake osungunuka ndi 2620 ℃, yachiwiri kwa tungsten ndi tantalum, koma kachulukidwe ake ndi otsika kwambiri, kotero mphamvu yake yeniyeni (mphamvu / kachulukidwe) ndi yaikulu kuposa tungsten, tantalum ndi zitsulo zina, zomwe zimakhala zogwira mtima kwambiri pogwiritsira ntchito ndi zofunikira zolemera kwambiri.Molybdenum akadali ndi mphamvu zambiri pa 1,200 ℃.
Main Features
Tungsten imakhala ndi malo osungunuka kwambiri, mpweya wochepa kwambiri, komanso mpweya wochepa kwambiri.The mankhwala zimatha tungsten kwambiri khola, osati zotakataka ndi mpweya ndi madzi kutentha firiji, insoluble mu hydrochloric acid, sulfuric acid, asidi nitric ndi alkali njira.Sungunulani m'madzi achifumu ndi kusakaniza kwa nitric acid ndi hydrofluoric acid.Pa kutentha kwambiri, imatha kuphatikiza ndi chlorine, bromine, ayodini, kaboni, nayitrogeni, sulfure, koma osati ndi hydrogenation.Malo osungunuka a tungsten amafika pa 3410 ℃, omwe akadali ndi mphamvu zambiri pafupifupi 1300 ℃, pomwe aloyi yochokera ku tungsten ilinso ndi mphamvu zambiri pafupifupi 1800 ℃ ndipo imakana bwino kutenthetsa.
Product Application
Chifukwa cha kachulukidwe mkulu wa tungsten, High kuuma, Choncho, wakhala mfundo yabwino kupanga mkulu enieni mphamvu yokoka aloyi, Izi mkulu enieni mphamvu yokoka aloyi anawagawa W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag ndi mndandanda wina waukulu, Mtundu uwu wa alloy uli ndi2.Main Mbalis mkulu chiŵerengero, mphamvu, wamphamvu mayamwidwe poizoniyu mphamvu, lalikulu matenthedwe madutsidwe, yaing'ono matenthedwe kukula koyefishienti, wabwino madutsidwe magetsi, weldability ndi processability wabwino, Amagwiritsidwa ntchito muzamlengalenga, ndege, asilikali, pobowola mafuta, zida zamagetsi, mankhwala ndi zina. mafakitale, monga zida zopangira zida, zoyikira kutentha, nyundo yowongolera chiwongolero ndi zida zolumikizirana monga chosinthira mpeni, chopumira dera, ma elekitirodi owotcherera, etc.
Malo amagetsi
Tungsten ili ndi pulasitiki yolimba, liwiro laling'ono la evaporation, malo osungunuka kwambiri komanso mphamvu yotulutsa ma elekitironi, kotero tungsten ndi ma aloyi ake amagwiritsidwa ntchito kwambiri pamagetsi ndi magetsi.Mwachitsanzo, tungsten waya ali mkulu mlingo wowala ndi moyo wautali utumiki, choncho chimagwiritsidwa ntchito popanga zosiyanasiyana babu filament, monga nyali incandescent, ayodini tungsten nyali, tungsten waya angagwiritsidwenso ntchito popanga mwachindunji otentha cathode ndi chipata chamagetsi oscillator chubu ndi zosiyanasiyana zida zamagetsi mu mbali matenthedwe cathode chowotcha.The2.Main Mbalima tungsten amapangiranso kukhala oyenera kuwotcherera kwa TIG ndi zida zina zama elekitirodi kuti azigwira ntchito yofananira.
Makampani opanga mankhwala
Tungsten mankhwala amagwiritsidwa ntchito ngati chothandizira ndi mitundu inorganic, monga tungsten disulfide ntchito ngati lubricant ndi chothandizira mu kupanga mafuta, bronze tungsten okusayidi ntchito mu zojambula, kashiamu kapena magnesium tungsten amagwiritsidwa ntchito phosphors.
Madera ena
Chifukwa tungsten ndi yofanana ndi galasi la boryl silicate, imagwiritsidwa ntchito popanga magalasi kapena zisindikizo zachitsulo.Tungsten imakhala ndi mphamvu zochepa ndipo imagwiritsidwa ntchito popanga zodzikongoletsera zagolide za tungsten.Kuphatikiza apo, tungsten imagwiritsidwanso ntchito ngati mankhwala a radioactive, ndipo zida zina zimagwiritsanso ntchito waya wa tungsten.
