Bọọlụ Corundum mullite

Uru ngwaahịa: nguzogide okpomọkụ dị elu, nguzogide corrosion, nguzogide ọxịdashọn, nkwụsi ike dị mma, yana ọnụego mgbanwe larịị dị ala.

Ngwa ngwaahịa: A na-ejikarị ya na ụlọ ọrụ mmanụ, nnukwu ihe na-emepụta sịntetị ammonia gasifier na ihe ọkụ ọkụ gas, ihe ọkụ ọkụ na-akwado ụlọ ọrụ na-akwado ihe akụrụngwa, wdg.

nkọwa ngwaahịa

A na-eji corundum na mullite brik mee corundum na mullite dị ka akụrụngwa, na-enwe nnukwu nrụgide wee gbaa ya ọkụ na oke okpomọkụ. Ngwaahịa nwere njirimara nke nguzogide okpomọkụ dị elu, nguzogide corrosion, nguzogide ọxịdashọn, nkwụsi ike dị mma, yana ọnụego mgbanwe dị ala.

Nkọwa nke brik kọlụm mullite:

1. Ihe dị arọ nwere ịdị mma nke ọma, ike mkpakọ dị elu, iguzogide gas dị iche iche na -emebi emebi, nkwụsi ike dị mma dị mma, conductivity thermal magburu onwe ya, na iyi mgbochi.

2. Ihe ndị dị fechaa nwere nhazi nke ime ụlọ, ike mkpakọ dị elu, nguzogide corrosion, nguzogide ujo ọkụ, nguzogide ọxịdashọn, okpomọkụ ọrụ dị elu na conductivity dị ala dị ala.
