Brik na-eguzogide phosphate
A na-akpọkwa brik ndị na-eguzogide phosphate dị elu nke aluminom dị elu nke na-eguzogide phosphate na-eguzogide. Brik ndị na-eguzogide Phosphate bụ ụdị ihe na-ajụ oyi, nke bụ akwa bauxite clinker ma ọ bụ ihe ngwọta phosphoric acid dị ka isi akụrụngwa, ma ọ bụ ihe nkedo aluminom phosphate, Mgbe igwe akọchara ya wee kpụọ ya, a na-agwọ ya ọkụ. na 400-600 ℃ iji mepụta ngwaahịa nrụgharị kemịkal jikọtara ọnụ. A na -ejikọta ya na brik. Iji zere nnukwu ịbelata n’oge a na -eji ngwaahịa ahụ na oke okpomọkụ, ihe ndị na -emepụta ihe na -adịkarị mkpa iwebata akụrụngwa ịgbasa ọkụ, dị ka kyanite, sillimanite, pyrophyllite, na carbide silicon. N’ịbụ nke nwere nnukwu brik alumina na seramiiki, nguzogide peeling ka mma, mana ọnọdụ ịkpa ahụ dị ala yana nkwụsị nzere, yabụ ekwesịrị ịgbakwunye obere ego nke fused corundum, mullite, wdg. Dabere na phosphoric acid na brik phosphoric acid na -eguzogide, brik na -agbanwe agbanwe nke sitere na brik aluminom nkịtị dị elu site na teknụzụ pụrụ iche na mgbakwunye kemịkaị emeela ka nguzogide abrasion dị mma na ibu nro dị nro, dị elu karịa brik alumina dị elu, ike dị mma, ngwa ngwa jụrụ oyi na nguzogide ọkụ ngwa ngwa, Na -eguzogide ọgwụ corrosion na abrasion. Ọdịdị ya dị elu karịa nke brik aluminom dị elu na klọmkụ rotary ciment.
Ọrụ aka:
(1) arụmọrụ nguzogide dị elu dị mma, ọnọdụ okpomọkụ na -ajụ oyi karịrị ogo 1770, nwere ike iguzogide oke okpomọkụ, na mgbanwe na oke okpomọkụ enweghị nnukwu mmetụta.
(2) Nkwụsi ike ọkụ dị mma nke ukwuu, iguzogide oyi ngwa ngwa na ọkụ ọkụ, na enweghị delamination ma ọ bụ peeling n’okpuru mgbanwe okpomọkụ.
(3) Nguzogide kemịkal, enweghị mgbawa na peeling ga-eme na ikuku ikuku na okpomọkụ nke 400-600 ° C.
(4) Ezi na -eguzogide na elu mkpakọ ike.
Achọpụtala brik Phosphate dị ka bricks dị mma maka klọm ciment na igwe ọkụ lime.
E nwere ụdị brik aluminna abụọ jikọtara phosphate: otu bụ brik phosphate nwere njikọ (nke a na-akpọ brik phosphate), na nke ọzọ bụ blọk aluminna dị elu nke phosphate (nke a na-akpọ brik na-eguzogide).
Brick phosphate na -eji ihe ngwọta acid phosphoric nwere mkpokọta 42.5% ruo 50% dị ka ihe nrachi, na nchịkọta bụ bauxite clinker calcined na okpomoku dị elu karịa 1600 Celsius C n’ọkụ na -agbanwe agbanwe. N’oge a na -eji brik ahụ eme ihe, phosphoric acid na -eji ezigbo ntụpọ bauxite eme ihe na brik iji jiri ụrọ na -emegharị emegharị mechaa, n’ikpeazụ, ọ na -etolite ihe nkedo nke mejupụtara cristobalite aluminom orthophosphate. Bricks na-eguzogide ọgwụ na-eji phosphoric acid ụlọ ọrụ na aluminom hydroxide na-emepụta ihe iji kwadebe ngwọta phosphate aluminom dị ka ihe mgbochi. Ogo ntụpọ ya bụ Al2O3: P2O5 = 1: 3.2. Nchịkọta a na -eji eme ya bụ nke brik phosphate. N’ime usoro iji brik, dị ka phosphate, a na-akpụ ihe nragide dabere n’ụdị cristobalite-ụdị aluminom orthophosphate.
Brick phosphate dị mma maka ọnụ ekwenti nke mpaghara ntụgharị nke ọkụ ọkụ rotary na akụkụ ndị ọzọ ebe brik dị mfe ịda, ọ bakwara uru maka mpaghara ọkụ. A na -ejikwa ya na igwe ihe ọkụ ọkụ, ihe ọkụkụ lime, ụlọ ọrụ carbon rotary kilns, wdg.
Arụmọrụ ngwaahịa: Ọ nwere njirimara nke ike mkpakọ dị elu na ọnọdụ ụlọ, ezigbo nkwụsi ike ujo dị elu, oke ọkụ na -eme ka ọ dị nro, nha ziri ezi, njupụta olu dị elu, yana ezigbo nguzogide.
