Graphite crucible refractory okpomọkụ

Graphite nwere ngwa dịgasị iche iche ma bụrụ otu n’ime mineral ndị na-eguzogide okpomọkụ dị elu. Dị ka graphite crucibles, a na-eji akụrụngwa graphite sitere n’okike mee ha ma na-ejigide ihe mbụ mara mma nke graphite. Gịnị bụ refractory okpomọkụ nke graphite crucible?

Uru nke graphite crucible:

1. Ọsọ ọkụ na-eduzi ọkụ ngwa ngwa, njupụta dị elu, belata oge mgbasa, chekwaa ike, nrụpụta mmepụta dị elu, ma chekwaa ikike mmadụ.

2. Ọdịdị n’ụdị, mgbochi mgbochi kpọmkwem na nkwụsi ike kemịkal dị mma.

3. Nchekwa gburugburu ebe obibi, nchekwa ike, nkwụsị nke corrosion, acid na alkali resistance, wdg.

Dị ka ọla kọpa anyị na-ahụkarị, aluminum, gold, silver, lead, zinc na alloys, ha niile nwere ike gbazee site na oghere graphite. Enwere ike ịhụ na okpomọkụ nke graphite crucible nwere ike ịnagide dị elu karịa ebe agbaze nke ọla ndị a.

Ebe mgbaze nke graphite bụ 3850°C±50°, ebe isi ya bụ 4250°C. Graphite bụ ihe dị ọcha nke ukwuu, ụdị mgbanwe kristal. Ike ya na-abawanye na mmụba nke okpomọkụ. Na 2000 Celsius, ike nke graphite na-abawanye. Ọbụlagodi na ọ na-ere ọkụ ọkụ dị oke elu, oke ibu dị ntakịrị, yana ọnụọgụ mgbasawanye thermal dịkwa obere.

Kedu oke nguzogide okpomọkụ dị elu nke graphite crucible? Ọ ga-ekwe omume iru ogo 3000, mana onye nchịkọta akụkọ na-atụ aro na ojiji gị ekwesịghị ịfe ogo 1400, n’ihi na ọ dị mfe ịnweta oxidized na ọ bụghị ogologo oge.
