Akwadoro brik corundum

Akwadoro brik corundum

Uru ngwaahịa: ike mkpakọ okpomọkụ dị elu (ihe ruru 340MPa), oke ọkụ na -eme ka ịdị nro dị elu (okpomọkụ dị nro mbụ dị elu karịa 1700 ° C), nkwụsi ike kemịkal dị mma, ezigbo acid na slag alkali, ọla a wụrụ awụ na nguzo iko.

Ngwa ngwa: Ihe ndị a na-ejikarị brik corundum fused bụ klọọkụ iko borosilicate, nnukwu ọwara ọkụ na-agbaze eriri, eriri na-enwu ọkụ na-arụ ọrụ, akwa na-agbaze igwe anaghị agba nchara, wdg. ngalaba nkọwa, ngalaba jụrụ oyi, ọdọ mmiri na -arụ ọrụ, wdg. Tụkwasị na nke ahụ, a na-ejikwa blọk und-β corundum fusedị n’uko ụlọ na ihe owuwu dị elu nke ite ọkụ, ndị na-ekesa ihe nkedo na-aga n’ihu na okporo ọkụ slide slide. Enwere ike iji brik corundum fused naanị maka ihe owuwu dị elu nke ebe a na -etinye iko na uzuzu SO2, dị ka usoro elu nke ọdọ mmiri na -arụ ọrụ, mgbidi ara dị n’akụkụ onye na -ere ọkụ, onye na -enwu obere ọkụ, mgbidi kwụgide na ihe ndị ọzọ. .

nkọwa ngwaahịa

Akụkụ kristal bụ isi nke bred corundum bụ corundum, yana ọdịnaya nke Al2O3 na -adịkarị elu karịa 93%. Nguzogide ịma jijiji ahụ nke brik corundum agwakọtara nwere njikọ chiri anya na ahụ. Nnukwu ngwaahịa corundum nwere nguzogide corrosion ka mma, mana adịghị ike ujo dị ọkụ. Enwere ike kewaa bred corundum agbakwunyere na bred fused α corundum, fused α-β corundum na bred fused β corundum.

Njirimara nke bred corundum:

1. Ike mkpakọ dị elu na ọnọdụ ụlọ (ruo 340MPa)

2. Oke ibu na -eme ka ọ dị nro (ọnọdụ ịkpa nro mbụ dị elu karịa 1700 ℃)

3. Ezigbo nguzogide kemịkal

4. Ezi iguzogide slag acid na alkali, ọla a wụrụ awụ na iko
