Ihe mkpuchi seramiiki ZTA Alumina: Ngwọta Nchedo Kachasị Elu nke Na-eguzogide Iyi

Ihe mkpuchi seramiiki ZTA (Zirconia Touckened Alumina)bụ ihe eji arụ ọrụ dị elu nke e ji eme ihe site n'itinye usoro zirconia (ZrO₂) n'ime matrix alumina (Al₂O₃). Nhazi a jikọtara ọnụ na-ejikọta ike siri ike nke alumina na njirimara nke mgbanwe usoro nke zirconia, si otú a na-eme ka ike mgbawa nke ihe ahụ na iguzogide mmetụta igwe dịkwuo mma. Ọdịdị obere ya dị otu ma dịkwa oke, yana njupụta buru ibu n'ozuzu ya bụ ≥3.95 g/cm³ na ike Rockwell (HRA) nke nwere ike gafere 85. A na-emepụta ihe a site na nhazi ntụ ntụ a nụchara anụcha, ịpị isostatic, na sintering okpomọkụ dị elu, na-eme ka ahụ na igwe kwụsie ike nke ọma.

Isi uru nke eriri a dị na ya bụ ezigbo nguzogide ya na ire ere. N'ebe a na-eyi ihe n'ụlọ ọrụ mmepụta ihe, ọnụego iyi nke seramiiki ZTA nwere ike ịdị ala karịa 30%-50% karịa nke seramiiki alumina nkịtị. Nguzogide iyi ya na-erite uru site na nnukwu nbibi siri ike na-eguzogide abrasive na usoro nnabata ike nke microcracks nke mgbanwe usoro zirconia na-emepụta. N'otu oge ahụ, ọ nwere ike ịdị oke njọ na kemịkalụ, na-eguzogide mbuze site na ọtụtụ acid na alkali media (ma e wezụga hydrofluoric acid na alkali siri ike). Ọ na-ejigide arụmọrụ kwụsiri ike n'okpuru ikpughe ogologo oge na okpomọkụ dị elu (okpomọkụ ọrụ kachasị elu ruo 850°C) na ọnọdụ ọrụ siri ike, yana ndụ ọrụ karịrị nke ihe nchekwa ígwè ọdịnala.

A na-ejikarị ZTA seramiiki lining eme ihe n'ọtụtụ ụlọ ọrụ ndị nwere oke mmebi, gụnyere mmepụta ike okpomọkụ, igwu ala, mmepụta simenti, ịgbaze ígwè, na sistemụ njikwa ihe. Ebe a na-eji ya eme ihe gụnyere ihe ndị na-ekewapụ cyclone, ikpere aka paịpụ, ihe na-eme ka fan impellers, chutes, hoppers, na ngwa nhazi ntụ ntụ dị iche iche. Ụzọ ntinye ya dị iche iche, dị ka njikọ, bolting, ma ọ bụ modular intedding, na-echebe ihe ndị e ji arụ ọrụ nke ọma. Nke a na-ebelata ugboro ole mmezi oge na mmefu mmepụta nke mmebi na-akpata, na-eme ka arụmọrụ na nchekwa nke sistemụ dịkwuo mma.

Na nchịkọta, ihe mkpuchi seramiiki ZTA alumina aghọwo ihe dị mkpa na teknụzụ n'ihe gbasara nchekwa iyi ụlọ ọrụ, n'ihi nhazi ya nke ọma na arụmọrụ dị mma nke a pụrụ ịchọpụta. Ọ na-enye nkwenye a pụrụ ịtụkwasị obi maka ọrụ kwụsiri ike ogologo oge nke akụrụngwa n'ebe siri ike, na-enye uru akụ na ụba na uru ngwa. Nnyocha na-aga n'ihu na ihe na nhazi ga-eme ka oke arụmọrụ ya na ọtụtụ ngwa ya dịkwuo elu.
