Isi arụmọrụ nke brik magnet

a. Refractoriness

N’ihi na agbaze ebe nke periclase (MgO) kristal dị nnọọ elu, na-eru 2800 ℃, na refractoriness nke magnesia brik bụ ndị kasị elu n’etiti general refractory brik, na-emekarị n’elu 2000 ℃.

b. Ike nhazi oke okpomọkụ

Okpomọkụ dị elu nke brik magnesia adịghị mma, na mmalite nke nro dị nro n’okpuru ibu dị n’etiti 1500 na 1550 Celsius C, nke karịrị 500 ° C dị ala karịa refractoriness.

c. Nguzogide slag

Brick Magnesium bụ ihe ndị na-atụgharị alkaline ma nwee nguzogide siri ike na slag alkaline dị ka CaO na FeO. Ya mere, a na-ejikarị ha eme ihe dị ka ihe masonry maka ọkụ ọkụ na-agbaze alkaline, mana nguzogide ha na slag acid adịghị mma. Brick Magnesium enweghị ike ịmekọrịta ihe na-eme ka acidic refractory, ha ga-emekọ ihe ọnụ na kemịkalụ wee mebie karịa 1500ºC. Ya mere, a pụghị ịgwakọta brik magnesia na brik silica.

d. Nkwụsi ike okpomọkụ

Nkwụsi ike nke ọkụ nke brik magnesia dị nnọọ njọ, ọ pụkwara iguzogide mmiri jụrụ oyi maka oge 2 ruo 8, nke bụ nnukwu ọghọm ya.

e. Nkwụsi ike olu

Ọnụ ọgụgụ mgbasawanye thermal nke brik magnesia buru ibu, ọnụọgụ mgbasawanye ahịrị n’etiti 20 ~ 1500 ℃ bụ 14.3 × 106, yabụ, a ga-ahapụkwa nkwonkwo mgbasawanye zuru oke n’oge usoro brik.

f. Thermal conductivity

The thermal conductivity nke brik magnesia dị ọtụtụ ugboro karịa brik ụrọ. Ya mere, oyi akwa dị n’èzí nke ọkụ ọkụ nke brik magnesia wuru kwesịrị n’ozuzu ya nwere mkpuchi mkpuchi okpomọkụ zuru oke iji belata okpomọkụ. Otú ọ dị, okpomọkụ nke brik magnesia na-ebelata na okpomọkụ na-arịwanye elu.

g. Mmiri mmiri

Magnesium oxide na-ezughị ezu na-emeghachi omume na mmiri iji mepụta mmeghachi omume ndị a: MgO+H2O→Mg(OH)2

A na-akpọ nke a mmeghachi omume hydration. N’ihi mmeghachi omume a, olu na-agbasa ruo 77.7%, na-eme ka brik magnesia mebiri emebi, na-eme ka mgbawa ma ọ bụ oke mmiri. A ghaghị ichebe brik magnesia site na mmiri n’oge nchekwa.
