Higher waikura Tungsten

whakaaro Tungsten waikura te tetahi o te whakangutungutu tino i roto i te piha haapiiraa o ngā matū pararopi. I roto i te tikanga ki te hoatu i te āhuatanga o te whakarewa, ki te tātari i te kounga o te whakarewa ake.

Āhuatanga Tungsten

Hei mahino te hiranga mahi o Tungsten waikura, mōhio e te whakarewa ano he parenga hiko, tau whakarea o roha rārangi, ira whakakoero tiketike.

He Tungsten parakore te kōngohe tiketike. Te whakarewa rewa i roto i te waikawa anake ka hana ki te pāmahana ^o 5000 C. tauhohe reira ki te waro, hanga rite te hua tauhohe o Tungsten carbide. Te pūhui hua he kaha nui.

Ko te waikura Tungsten tino noa - trioxide Tungsten. Ko te painga matua ko te kaha o te pūhui ki whakahokia puehu whakarewa hanga rite i-hua o waikura raro.

Metal he kiato tiketike, friability me te kaha i pāmahana iti ki te hanga i waikura Tungsten.

alloys Tungsten

Kua tawhiti Scientists kotahi-wāhanga momo o alloys, titoa nei o tetahi atu ranei huānga. Ko te pūhui mohiotia tino pai o Tungsten me molybdenum. faarahi koranu Alloying huānga molybdenum Tungsten kurut kaha.

E whakaaro alloys Single-wāhanga ki te hei pūhui: Tungsten - zirconium, Tungsten -gafny, Tungsten - Niobium. piri te ukanga mōrahi Tungsten rhenium. Tāpiri i te reira e kore e pā te mahi o te whakarewa tutu.

Takanga o te konganuku

e kore e taea e tikanga tikanga riro i te alloys whakangutungutu Tungsten: pa te ira whakarewa whakakoero tonu haere ki te puka haurehu waihā. Ko te whāinga matua ko te takanga o te iahiko whakarewa parakore. I roto i te tauine ahumahi ki te whiwhi Tungsten metallurgy koranu paura whakamahia. Ki te mahi i tenei, te hanga i tētahi tikanga tukatuka motuhake mā te whakamahi i te ereraa i.

Te riroraa i roto i te āhua

Tungsten waikura, WO ₃ te tuku ki rite te pūhui rawa nei tātai. e kore e puta ia i roto i te āhua i roto i tona ahua parakore, engari ko te wahi o tokahuke Tungsten. Ko te tukanga o te tangohanga, me te tukatuka o whakarewa whakangutungutu tā maha ngā wāhanga.

waikura teitei ora ake o Tungsten te i te papatipu ore. kawea fakatupulaki atu o te pūhui i roto i, me te i muri i te maimoatanga ki te whakarewa parakore taratahi.

I roto i te tukanga ahumahi he waea Tungsten angiangi e matakitaki ana i roto i te tikanga ki te tino tango i nga poke. Kore, te āhuatanga hangarau o te hua oti ka kia tino heke.

Ngā wāhanga o te whakamahi o te Tungsten

Me pēhea te ki te ora Tungsten waikura? Hauwai, e pāhekoheko ki te pūhui, tauturu ki te tiki whakarewa parakore. Kei te hiahiatia te reira i roto i te hanga o ngā whenu kakawaea, te hanga korere X-ray, hatete mata me oumu korehau e prednaznachngy hoki te whakamahi i pāmahana teitei.

Steel, te huānga alloying he ai Tungsten, āhuatanga e ngā āhuatanga kaha teitei. Products hanga o taua koranu e whakamahia i roto i te hanga o taputapu hauora, tapahi fakahū mo puna kōhao. whakaaro te painga matua o te pūhui te ātete ki te deformation aunoa.

Ko te tino iti te tūponotanga o tupu i roto i te mahi o nga kapiti hua oti me maramara. Ko te waitohu tino rongonui o te parahi, o nei ngā Tungsten te, kua whakaaro te reira ki te riro.

Mai i tenei e mau whakarewa onge hua kaiwhakakökï kounga teitei, ngā peita, uhi motuhake me crucibles Tungsten m. N. I roto i hou ahumahi karihi te whakamahia whānui me ngā mō te tikanga ururua iraruke.

whakarewa refractoriness whai wāhi nui i roto i te fehokotaki'anga pewa. Mai whakaaro te Tungsten i roto i te puka parakore te he whakarewa onge, ki tona tukanga faaineineraa kawea te haamaitairaa, me te hangaruatanga i te ore Tungsten. I roto i te puka parakore te mea he tae hina marama ki te umeraa konganuku āhuatanga. alloys Tungsten Paerewa, tuku ki rite stellite, Kei hoki hinu, me te chromium. Ko te wāhanga matua i roto i taua pūhui tavini konukurahina. He alloys i roto i te tono i roto i te engineering aunoa.

waikura Tungsten

He aha he waikura ngā Tungsten (6), te tātai o e kua te ahua o WO _3? Ka taea e Metal whakaatu ngā āhua hāora: pūmautanga mōrahi he rerekē ki te honohono, whakarewa (4), me te (6). WO momo hononga tuatahi ₂ pā ana ki waikura waikawa me te he te āhuatanga e whai ake nei: ira whakakoero tiketike, me te kiato ngā. Ko tata rewakore i roto i te wai i tenei pūhui matū, engari e taea te rewa ina hana i roto i te waikawa me kawakore. I roto i te ahumahi matū te whakamahia te reira rite te whākōkī i roto i te tahi mau tauhohenga. Hei tauira, Aue, pūhui ₂ whakamahia i roto i te hanga o ngā hua uku.

whakaaturia hoki Tungsten waikura he honohono, o (6) te āhuatanga āhuatanga waikawa. tali tēnei pūhui te ki kawakore, engari e kore e ahei o ā tātau i roto i te wai. Hoatu e te rewa wāhi pūhui nui, Kei te whakamahia te reira anake hei tukanga whakatere matū.

mutunga

I roto i te akoranga o te matū pararopi hāngai ana ki te ako o waikura, te tātaritanga o ratou āhuatanga, me te ahumahi āhuatanga primeneniyav. Hei tauira, i roto i te mahi whakamātautau whakamutunga iwa graders whai tuku: "Titoa waikura Tātai parahi, rino, me te Tungsten, ka whakatau ano ratou āhuatanga taketake matū."

I roto i te tikanga ki te pai akakoromaki i te mahi, me whai koe i te whakaaro o nga āhuatanga o te waikura. Whakaaro aua pūhui ā-rua, i roto i nei te rua i te huānga, ko te hāora. waikura katoa ki te whakarōpū ki ngā rōpū e toru: taketake, waikawa, amphoteric.

Iron me parahi he āhuatanga o te rōpū whakawhiti, kia taea e o honohono, tāupe. Hoki parahi taea te tuhituhia kōwhiringa e rua anake waikura whakaahua āhuatanga taketake - Cu ₂ E te ko CuO.

e kore ko te rino i roto i te matua iti-rōpū o ngā āhuatanga matū, na reira ko te āhua pitihāoratanga +2 me +3. I roto i enei take, i te momo e whai ake nei o waikura e hanga e - FeO ko Fe ₂ E _3.

Tungsten i roto i pūhui ā-rua ki te hāora i roto i te nuinga o maha faaite honohono (4), me te (6). whakaatu rua o te waikura whakarewa āhuatanga waikawa, na e whakamahia ratou i roto i te ahumahi rite accelerators tukanga matū.

Ko te whakaaro matua o te waikura Tungsten ko te wehe o enei whakarewa parakore i roto i tono i roto i te ahumahi matū, me te metallurgical.
