Alumina seramiiki membrane: Isi ihe maka teknụzụ dị elu-Arụmọrụ nkewa

Alumina seramiiki membran bụ porous inorganic akpụkpọ ihe nke mbụ mejupụtara aluminum oxide (Al₂O₃). Nkwụsi ike nke kemịkalụ ha dị mma, nkwụsi ike ọkụ, na ike arụ ọrụ na-eme ka ha bụrụ ihe dị mkpa na-agbanwe na membran polymer organic ọdịnala, yana nchekwa na ike gburugburu ebe obibi. Ọdịdị microporous pụrụ iche ha na nguzogide corrosion dị elu na-eme ka ha bụrụ ezigbo nhọrọ maka akpụkpọ anụ polymer organic omenala, karịsịa na gburugburu ebe dị njọ dị ka okpomọkụ dị elu na acid siri ike na alkalis.

N'usoro, akpụkpọ anụ seramiiki alumina na-egosipụtakarị usoro pore nke hierarchical, nke nwere macropores na oyi akwa nkwado, mesopores na oyi akwa mgbanwe, na obere pores na oyi akwa nkewa. Nhazi a na-ekewa nke ọma n'ụdị dị iche iche. Dabere na nha pore, enwere ike ịkewa ha dị ka akpụkpọ anụ microfiltration (0.1-10 μm), membranes ultrafiltration (0.01-0.1 μm), na nanofiltration membranes (0.01-0.1 μm).<0.01 μm). They are widely used in liquid filtration, gas separation, and catalytic reactions. For example, in wastewater treatment, alumina ceramic membranes effectively retain suspended particles and microorganisms. In the pharmaceutical industry, they ensure the purity and safety of pharmaceutical production processes.

Usoro nkwadebe maka akpụkpọ anụ seramiiki alumina gụnyere siri ike -stetile sintering, sol-gel, na anodic oxidation. Sol-gel, n'ihi ikike njikwa ya dị elu yana nkesa oke nha, abụrụla teknụzụ bụ isi maka nkwadebe akpụkpọ ahụ dị elu-. Mgbanwe ihu ma ọ bụ iji ihe ndị ọzọ na-emekọ ihe (dị ka carbon nanotubes na metal oxides) nwere ike na-ebuli elu hydrophilicity, mgbochi- ihe ndị na-emebi emebi, yana ịrụ ọrụ nkewa họrọ.

N'ọdịnihu, na ọganihu nke sayensị ihe ndị na-ahụ maka akpụkpọ ahụ, akpụkpọ anụ seramiiki alumina ga-egosipụta ike dị ukwuu na mpaghara ndị na-apụta dị ka mmiri mmiri mmiri, nchacha hydrogen, na nzacha biomedical. Ogologo ndụ ha ogologo, obere ume ike, na ijikwa ya na-egbo mkpa mmepe zuru ụwa ọnụ, na-eme ka ha bụrụ isi ihe na-eme ka ọganihu nke teknụzụ nkewa akwụkwọ ndụ akwụkwọ ndụ.
