1. Waihona
ʻO nā huahana Tungsten a me ka molybdenum he mea maʻalahi ke hoʻololi a hoʻololi i ke kala, no laila pono lākou e mālama i kahi kaiapuni me kahi 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 waikawa, e ʻoluʻolu e hoʻolohe!
2. Embrittlement haumia
(1) Ma ka wela kiʻekiʻe (kokoke i ka helu heheʻe o ka metala), e hana ia me nā metala ʻē aʻe (ka hao a me kona mau ala, nickel a me kona mau ala, a me nā mea ʻē aʻe), i kekahi manawa e hoʻoheheʻe ʻia ka mea.I ka hana ʻana i ka mālama wela o nā huahana tungsten a me molybdenum, pono e uku ʻia!
Pono e hana ʻia ka hoʻomaʻamaʻa ʻana i ka wela i loko o ka momi (ma lalo o 10-3Pa), e hoʻemi ana (H2) a i ʻole ke kinoea inert (N2, Ar, etc.) lewa.
(2) E lilo ana nā huahana Tungsten a me molybdenum i ka embrittle ke hana lākou me ke kalapona, no laila, mai hoʻopā iā lākou i ka wā e hana ʻia ai ka mālama wela ma kahi mahana ma luna o 800°C.Akā ʻo nā huahana molybdenum ma lalo o 1500 ℃, liʻiliʻi loa ka degere o ka embrittlement i hana ʻia e ka carbonization.
3. Mīkini
(1) ʻO ke kuʻi, ke kuʻi, ke ʻoki ʻana, ka ʻoki ʻana, a me nā mea ʻē aʻe o nā huahana pāpaʻi tungsten-molybdenum e maʻa mau i nā māwae ke hana ʻia ma ka lumi wela, a pono e wela.I ka manawa like, ma muli o ka hana kūpono ʻole, i kekahi manawa e hele mai ka delamination, no laila ua ʻōlelo ʻia ka hana hoʻomehana.
(2) Eia naʻe, e lilo ka pā molybdenum i mea palupalu i ka wā i wela ai ma luna o 1000 ° C, kahi e pilikia ai ka hana ʻana, no laila pono e uku ʻia.
(3) I ka mīkini wili ʻana i nā huahana tungsten a me molybdenum, pono e koho i kahi ʻano wili kūpono no nā manawa like ʻole.
4. ʻO ke ʻano o ka wehe ʻana i ka oxide
(1) He mea maʻalahi nā huahana Tungsten a me ka molybdenum e hoʻohemo.Ke hoʻoneʻe ʻia nā oxides kaumaha, e ʻoluʻolu e hāʻawi i kā mākou hui a mālama ʻia me ka waikawa ikaika (hydrofluoric acid, nitric acid, hydrochloric acid, etc.), e ʻoluʻolu e hoʻolohe i ka wā e hana ai.
(2) No nā oxide māmā, e hoʻohana i kahi mea hoʻomaʻemaʻe me nā abrasives, e holoi me kahi lole palupalu a i ʻole ka sponge, a laila holoi me ka wai mahana.
(3) E ʻoluʻolu e nalowale ka luster metala ma hope o ka holoi ʻana.
5. Hoʻomalu no ka hoʻohana
(1) He oi loa ka pepa tungsten-molybdenum e like me ka pahi, a e oki paha na lima o na pahu ma na kihi a me na maka hope.I ka hoʻohana ʻana i ka huahana, e ʻoluʻolu e hoʻokomo i nā mea pale.
(2) ʻO ka nui o ka tungsten ma kahi o 2.5 mau manawa o ka hao, a ʻo ka nui o ka molybdenum ma kahi o 1.3 mau manawa o ka hao.ʻOi aku ke kaumaha o ke kaumaha maoli ma mua o ka hiʻohiʻona, no laila e hōʻeha ka lima i nā kānaka.Manaʻo ʻia e hana i ka hana lima inā ʻoi aku ke kaumaha ma lalo o 20KG.
6. Hoʻomalu no ka lawelawe ʻana
ʻO nā huahana tungsten a me ka molybdenum o nā mea hana pāʻani molybdenum he mau metala brittle, kahi i maʻalahi i ka haki a me ka delamination;no laila, i ka lawe ʻana, e makaʻala ʻaʻole e hoʻopili i ka haʻalulu a me ka haʻalulu, e like me ka hāʻule ʻana.Eia kekahi, i ka wā e hoʻopili ai, e ʻoluʻolu e hoʻopiha i nā mea hoʻopuʻi.
