Heat karaihe ātete: hokohoko āhuatanga me Scope

Karāhe - tetahi o nga rauemi matamua a tino pūkenga. Ko te katoa a tawhio noa tatou hua koata, engari ko te tikanga e kore matou e whakaaro nui rawa e pā ana ki ona āhuatanga. Ka taea e ratou rerekē nui i runga i te whakamahi tikanga o ngā hua heke mai rānei. Ko tētahi o nga momo tino noa ko te karaihe wera-tohu. Kia kitea o roto pehea rerekē reira i te mua, me te wahi e hāngai ana.

karaihe wera-tohu

Karāhe Ko te taonga pararopi. Kei te āhuatanga i te reira e te āhuatanga o te totoka, wai whakarewa, he reira he pokey tiketike. rerekē tōna fragility, kaha, kiato, me te wera motuhake whānui me whakawhirinaki i runga i nga poke.

Maoro, Kua whakawhanakehia rauemi i e riro āhuatanga karaihe mohiotia, pērā i te ahi resistance. Ko te tawhā matua e he rerekē i ētahi atu wera karaihe karaihe ātete - te pāmahana i nei pupuritia reira ona āhuatanga. Ka taea e te tu te reira i wera noa 1000 degrees, i tona "hoa" anganga kua i 80 nekehanga.

I refractoriness pā te hanganga me te matotoru o te rauemi. Ki te he nui te karaihe, me kei roto he rahi teitei o waikura alkali, ka waiho i te reira roa. karaihe wera-tohu te nuinga ātete - kiripaka. Ka taea e te tu te reira i huringa pāmahana nui, me te he pāmahana e koropupu teitei (2230 nekehanga).

Production o karaihe wera-ātete

Tikanga, te karaihe ko te ranunga o te maha wāhanga. Ki te tango i te paerewa rauemi takawai onepu, kotakota, me te houra. E te tahu ratou ki pāmahana tiketike rawa (1700 ° C), he aha e rewa ratou, ka i konatunatua ki te tahi i te tahi. I muri iho, i ringihia te ranunga ki te tine whakarewa (kahore e ratou i konatunatua tika ki te rerekētanga kiato), a ka āta te matao o.

Hei hoatu i te āhuatanga e tika ana ki e tapiritia enei wāhanga, me ētahi atu matū. Hei hanga i te karaihe wera-tohu, te whakamahi i waikura rerekē. Ko te kupu, i roto i te borosilicate kei rauemi waikura boron i roto i te takawai - waikura silicon.

Ētahi atu kaha ka whai reira, ki te whakamahi koe i te maha o ngā paparanga. Hoki tenei whakaaro kua hoatu reira ki whakamatao i tino. E u rau oti, horoia, ka tapahia ki te rahi e hiahiatia ana. Na e herea ia he maha o pepa karaihe ki tetahi ki tetahi i te tikanga o te waerau motuhake. Kei te tahu te mutunga pa karaihe "hanawiti" i 660-680 nekehanga.

tono

Ko rongonui i roto i te kīhini Heat karaihe ātete. No te mea kua meinga reira oumu, me te kanisā. Ko hoki hua Common o tenei rauemi he kanga ahi. Te kiripaka karaihe whakamahia i roto i te hanga o te muka whatu, he tirohanga Fresnel, crucibles, insulators, a na i runga i. D. Borosilicate whakamahia hoki mōhiti optical, rihi, whakaata karu.

I roto i te oko o te karaihe wera-ātete maha painga. whakakeke ana te reira i te ara ahi tuwhera, he roa. Ko makona e mangere te rauemi, me te kore e oxidize ka wera, e kore e pera te huri i te hā o rihi. e kore he kaupapa ki te waikura, me te tauine ia.

O te akoranga, he drawbacks ara he karaihe wera-tohu. e kore e huru te reira ki te hua koi ranei iti i roto i te pāmahana. e kore kia hoatu rihi i taua rauemi i runga i te ahi nui i muri tonu i te pouaka tio. I tua atu, e kore e te karaihe fireproof paorooro-tohu, me te maturuturu ona kore utu reira.
