Corundum Bricks-Hengli
Atụmatụ
Brick Corundum, nke a makwaara dị ka brik alumina, bụ ngwaahịa na-eme ka alumina dị elu nwere ọtụtụ atụmatụ dị mkpa:
1. **Elu Ọcha: **Ihe mejupụtara nke ihe karịrị 90% alumina (Al2O3), na-eme ka ihe nrụpụta dị mma.
2. ** Nguzogide oke okpomọkụ: **Nwere ike iguzogide okpomọkụ ruo 1900 Celsius, na-eme ka ha dị mma maka gburugburu ebe okpomọkụ dị elu na-achọsi ike.
3. ** Ike Mechanical: **Brick Corundum nwere ike mkpakọ dị elu na nguzogide dị mma, na-enyere ha aka ijikwa ibu dị arọ na ọnọdụ abrasive.
4. ** Nguzogide corrosion: **Ha na-eguzogide corrosion sitere na slags, acids, alkalis, na kemịkalụ ndị ọzọ, na-agbatị ndụ ha na gburugburu ebe siri ike.
5. ** Obere Ike: **Porosity dị ala na-enyere aka igbochi ntinye nke ihe ndị a wụrụ awụ na gas, na-eme ka ịdịte aka na ihe mkpuchi ọkụ.
6. ** Nkwụsi ike nke okpomọkụ: **Ha na-egosipụta nkwụsi ike dị mma na nguzogide okpomọkụ, nke dị oke mkpa maka usoro metụtara mgbanwe okpomọkụ ngwa ngwa.
7. ** Nkwụsi ike akụkụ: **Ọdịnaya alumina dị elu na-eme ka brik ahụ na-edobe ọdịdị ha na olu ha na oke okpomọkụ, na-egbochi ọdịda nhazi.
Atụmatụ ndị a na-eme ka brik corundum dị mma maka ojiji na ngwa dị elu dị elu, gụnyere ọkụ ọkụ, stovu na-ekpo ọkụ ọkụ, ladles ígwè, na ọkụ ọkụ ndị ọzọ na-arụ ọrụ na kilns.
