Tungsten disulfide pauda
Hōʻike huahana
ʻO Tungsten disulfide kahi hui i hui ʻia me ʻelua mau mea, tungsten a me sulfur, a ua hoʻopau pinepine ʻia ʻo WS2.Ma ke ʻano o nā waiwai kino, ʻo ka tungsten disulfide kahi paʻa ʻeleʻele me kahi ʻano aniani a me kahi luster metallic.He kiʻekiʻe kona helu heheʻe a me ka paʻakikī, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai a me nā ʻakika maʻamau a me nā kumu, akā hiki ke hana me nā kumu ikaika.Hoʻohana nui ʻia ia i nā lubricants, nā lako uila, nā catalysts a me nā māla ʻē aʻe.Ma ke ʻano he lubricant, hoʻohana nui ʻia ka tungsten disulfide i nā mīkini like ʻole a me ka hana ʻana o nā kaʻa ma muli o kāna mau mea lubrication maikaʻi loa a me ke kūpaʻa ʻana o ka wela wela.I nā mea uila, ʻo ka paʻa wela kiʻekiʻe o ka tungsten disulfide a me ka conductivity maikaʻi e lilo ia i mea hoʻopau wela kūpono.Eia kekahi, ma muli o kona ʻano graphite-like, tungsten disulfide kekahi hana koʻikoʻi i ka hana pākaukau.Ma ke kahua o nā catalysts, hoʻohana ʻia ka tungsten disulfide ma ke ʻano he catalyst no ka decomposition methane ma muli o kona ʻano kūikawā.I ka manawa like, loaʻa i ka tungsten disulfide ka mea hiki ke hoʻohana i nā mea superconducting a me nā composites.

1) Nā mea hoʻohui paʻa no ka lubricating grease
ʻO ka hui ʻana i ka pauka micron me ka momona ma kahi ratio o 3% a hiki i 15% hiki ke hoʻonui i ke kūpaʻa kiʻekiʻe o ka mahana, ke kaomi nui a me nā waiwai anti-wear o ka momona a hoʻolōʻihi i ke ola lawelawe o ka momona.
ʻO ka hoʻopuehu ʻana i ka pauka nano tungsten disulfide i loko o ka ʻaila lubricating hiki ke hoʻonui i ka lubricity (friction reduction) a me nā waiwai anti-wear o ka ʻaila lubricating, no ka mea, he antioxidant mana ka nano tungsten disulfide, hiki ke hoʻolōʻihi i ke ola lawelawe o ka ʻaila lubricating.
2) Lubrication uhi
Hiki ke hoʻokuʻu ʻia ka pauka Tungsten disulfide ma ka ʻili o ka substrate e ka ea maloʻo a me ke anuanu ma lalo o ke kaomi o 0.8Mpa (120psi).Hiki ke hoʻopā ʻia ma ka lumi wela a ʻo ka uhi ʻana he 0.5 micron ka mānoanoa.ʻO kahi ʻē aʻe, ua hui ʻia ka pauka me ka isopropyl alcohol a hoʻopili ʻia ka mea paʻa i ka substrate.I kēia manawa, ua hoʻohana ʻia ka tungsten disulfide coating i nā kula he nui, e like me nā ʻāpana kaʻa, nā ʻāpana aerospace, nā bearings, nā mea ʻokiʻoki, ka hoʻokuʻu ʻana, nā ʻāpana valve, nā pistons, nā kaulahao, etc.
3) Kākoʻo
Hiki ke hoʻohana ʻia ʻo Tungsten disulfide ma ke ʻano he catalyst ma ke kahua petrochemical.ʻO kāna mau mea maikaʻi ʻo ia ka hana kiʻekiʻe kiʻekiʻe, ka hana catalytic kūpaʻa a hilinaʻi, a me ke ola lawelawe lōʻihi.
4) Nā noi ʻē aʻe
Hoʻohana ʻia ʻo Tungsten disulfide ma ke ʻano he palaki non-ferrous i ka ʻoihana kalapona, a hiki ke hoʻohana ʻia i nā mea superhard a me nā mea uea welding.
