ʻO kahi mea me nā talena kūikawā-Tungsten
Hiki iā ʻoe ke loaʻa ka tungsten ma ka hana i ka wā e wela ai ka wela.No ka mea, ʻaʻohe metala ʻē aʻe e hoʻohālikelike me ka tungsten i ka wā e pili ana i ka pale wela.ʻO Tungsten ka helu hoʻoheheʻe kiʻekiʻe loa o nā metala āpau a no laila kūpono no nā noi wela kiʻekiʻe.Hōʻike ʻia ia e kahi ...Heluhelu hou aku -
ʻO ka mālama ʻana no ka hoʻohana ʻana i nā huahana tungsten a me molybdenum
1. ʻO ka mālama ʻana i nā huahana Tungsten a me ka molybdenum e maʻalahi i ka oxidize a hoʻololi i ka waihoʻoluʻu, no laila pono e mālama ʻia i loko o kahi kaiapuni me ka haʻahaʻa ma lalo o 60%, kahi mahana ma lalo o 28 ° C, a hoʻokaʻawale ʻia mai nā kemika ʻē aʻe.Hiki ke hoʻoheheʻe ʻia nā oxides o ka tungsten a me ka molybdenum i ka wai a he acidic, pl ...Heluhelu hou aku -
ʻenehana hana o ka pā tungsten
ʻO ka powder metallurgy tungsten ka mea maʻamau i ka palaoa maikaʻi, koho ʻia kona blank e ke kiʻekiʻe kiʻekiʻe o ka hoʻoulu ʻana a me ke ʻano o ka ʻōwili ʻana, ke hoʻomalu ʻia ka mahana ma waena o 1500 ~ 1600 ℃.Ma hope o ka hakahaka, hiki ke ʻōwili hou ʻia ka tungsten, hana ʻia a milo paha.ʻO ka paʻi ...Heluhelu hou aku -
ʻO ka hoʻohana ʻana i ka uea Molybdenum, ka pauka Molybdenum, a me MoO3
Hoʻohana MoO3: Hoʻohana nui ʻia i ka pauka metallurgy e hoʻomākaukau i ka pauka molybdenum, hana i nā catalysts, nā mea hoʻohui kila a me nā puaʻa.ʻO ka pauka Molybdenum ka wehewehe ʻana i ka huahana: ʻO kēia huahana he pauka metala hina, e hoʻoheheʻe mālie ʻia i ka lewa, a hoʻomākaukau ʻia ma ka hoʻemi ʻana i ka molybdenum trioxide me ka hydrogen....Heluhelu hou aku
