Aluminom Hydroxide dị mma

Ojiji: n'ime mmepụta nke aluminom hydroxide. Isi ihe: a na-agbaze mkpụrụ aluminom hydroxide, gwakọta ya na mmiri aluminate. A na-etinye ihe nkwusioru ahụ na-esi na ya apụta ma na-agwakọta ya na carbon dioxide. A na-ekewapụ aluminom hydroxide na mmanya nne. A na-asa aluminom hydroxide.

Ihe mepụtara a metụtara mmepụta nke aluminom hydroxide.

Usoro esi enweta ezigbo aluminum hydroxide [1] nke a na-eme usoro ahụ n'ọkwa abụọ. Na nke mbụ, a na-eji hydrochloric acid eme ka ngwọta aluminate ghara ịdị irè, a na-ejikwa aluminum hydroxide a gbasaara nke ọma dị ka mkpụrụ nke ngwọta aluminate supersaturated na nkebi nke abụọ.

Ihe na-adịghị mma nke usoro a bụ nnukwu ọnụ ahịa nke sitere na mwepụ nke caustic alkali site na acid, mkpokọta nke ihe na-adịghị ọcha na ngwọta, wdg.

Ihe kacha nso n'ihe mepụtara ugbu a bụ ụzọ [2] nke e ji ntụ ntụ aluminom hydroxide mee maka imepụta ezigbo aluminom hydroxide dị ka mkpụrụ.

Ihe na-adịghị mma nke usoro a bụ ngwọta wintopo dị elu.

Ebumnuche nke ihe mepụtara a bụ ibelata ọnụ ahịa ike nke otu nkeji site n'ịbawanye mmepụta nke ezigbo aluminum hydroxide.

A na-eji carbon dioxide emepụta ihe ngwọta aluminate, a na-ejikwa usoro carbonization eme ihe nke ukwuu n'ime osisi alumina na-arụ ọrụ site na sintering. Ojiji nke carbonization nwere ike inye hydroxide mmepụta dị elu.

Nha ọka nke aluminom hydroxide nke a na-enweta n'usoro carbonization na-adaberekarị na okpomọkụ nke carbonization na nhazi nke ngwọta aluminate (ntinye nke alkali na alumina).

Usoro a maara (Ọla dị mfe. 1937, Nke 10, S. 8-15) mmepụta nke ezigbo aluminum hydroxide site na usoro carbonization, gụnyere nhazi nke carbon dioxide ultracracker aluminate solutions (ntinye 200 g/l) na obere okpomọkụ (30)^gbasaraC).

Ọ bụ ezie na usoro a na-enye ezigbo aluminum hydroxide dị elu, ojiji ya agaghị ekwe omume n'ihi nsogbu teknụzụ na-ebilite na ọkwa ikpeazụ nke usoro ahụ: Ngalaba mmiri ozuzo na ịsa ahụ.

Otú ọ dị, mgbe eji usoro nizkokontsentrirovannye nke carbonization ada ada.

Nha ọka nke aluminom hydroxide enwetara n'okpuru ọnọdụ ndị a, nke a na-eji ihe mejupụtara na-abụghị otu na oke ọdịnaya nke ihe ndị dị nro eme ihe.

Ihe mepụtara ya bụ na n'ime usoro mmepụta nke ezigbo aluminum hydroxide, gụnyere ịkpụcha mkpụrụ aluminum hydroxide, ịgwakọta ya na ngwọta aluminate, mee ka nkwusioru ahụ pụta ka ọ dị ọhụrụ site na ịkpalite, kewapụ aluminum hydroxide site na nne mmanya ma saa ya, tupu ekewapụ aluminum hydroxide site na nne mmanya, a na-eji carbon dioxide agwọ slurry ahụ.

Nnyocha egosila na mgbe a na-edozi ngwọta carbon dioxide aluminate nke nwere nnukwu ihe siri ike, nha nke ihe ndị ahụ fọrọ nke nta ka ọ bụrụ otu.

Mgbe a na-eme mkpụrụ a gwepịara egwepịa na mmiri aluminate supersaturated, ma na-eme ka ihe mkpuchi ahụ pụta ka mma site na ịkpalite ya, ọ na-emepụta nnukwu aluminum hydroxide nke gbasaara nke ukwuu. Agbanyeghị, mmepụta nke ezigbo aluminum hydroxide na-enweghị nhazi ọzọ nke ihe mkpuchi ahụ dị obere ma dabere na mkpokọta caustic alkali na ngwọta ahụ: ka oke nke alkali dị, otú ahụ ka mmepụta ahụ na-ebelata.

Mgbe a na-ahazi carbon dioxide, a na-enye nkwụsị mbụ site na mmepụta nke aluminum hydroxide bụ otu ihe ahụ dị ka nhazi nke nkwụsịtụ mgbe mmalite mkpughe gasịrị, Otú ọ dị, ọ na-eme ka nha nha nke aluminum hydroxide dịkwuo elu nke ukwuu.

Enwere ike iji ngwaike dị ugbu a mee ihe n'usoro a.

Usoro a kacha mma osisi alumina dabere na teknụzụ spechitelnoj.

Iji data sitere na ọtụtụ nnwale na-egosi na nhazi nke mmiri mmiri hydrate nwetara mgbe ekpughere ngwakọta nke mmiri aluminate na mkpụrụ a gbuturu agbutu, carbon dioxide na-enye ohere ịnweta ezigbo aluminum hydroxide ma hụ na mmepụta ngwaahịa dị elu.
