1, Gịnị bụihe mkpuchi na-eguzogide iyi silicon carbide?
Silicon carbide (SiC) bụ ihe mejupụtara silicon na carbon, nke nwere nhazi kristal pụrụ iche ma kwụsie ike. Akụkụ nhazi ya bụ SiC na CSi tetrahedra jikọtara ọnụ. Ihe mkpuchi na-eguzogide iyi silicon carbide bụ oyi akwa nchebe nke ejiri ihe silicon carbide mee iji chebe ime akụrụngwa ka ọ ghara imebi ma dọka. Enwere ike ime ya n'ụdị dị iche iche, dị ka mgbaaka seramiiki, ihe mkpuchi seramiiki, wdg, wee tinye ya na mgbidi dị n'ime nke akụrụngwa dị ka pipeline, ahụ ọkpọkọ, na silos ndị nwere ike ibute mbuze na esemokwu ihe.
2, Uru nke mkpuchi na-eguzogide iyi silicon carbide
1. Ike siri ike na oke nguzogide iyi: Ike nke seramiiki silicon carbide dị oke elu, nke abụọ karịa dayamọnd kacha sie ike n'okike. Ike siri ike a na-enye ya ike iyi siri ike, nwee ike iguzogide mbuze ọsọ ọsọ na esemokwu siri ike nke ihe, na-agbatị ndụ ọrụ nke akụrụngwa nke ukwuu, na-eme ka ọ bụrụ ihe zuru oke na-eguzogide iyi n'ọhịa nke iyi dị arọ. Ma e jiri ya tụnyere ihe ndị ọzọ na-eguzogide iyi nkịtị, ihe mkpuchi na-eguzogide iyi silicon carbide nwere uru dị ukwuu na iguzogide iyi, nke nwere ike ibelata ugboro ole mmezi na nnọchi akụrụngwa maka ụlọ ọrụ yana obere ọnụ ahịa mmepụta.
2. Njupụta dị ala na ibu dị mfe: Silicon carbide nwere njupụta dị ala karịa ọla dịka ígwè. Dịka ọmụmaatụ, njupụta nke seramiki silicon carbide sintered reaction sintered bụ naanị 3.0g/cm³, ebe njupụta nke seramiki silicon carbide sintered na-enweghị nrụgide bụ 3.14-3.0g/cm³. N'ihe gbasara otu olu ahụ, ibu nke mkpuchi silicon carbide na-eguzogide iyi dị mfe, nke na-eme ka ọ bụghị naanị na ọ na-eme ka njem na ntinye dị mfe, kamakwa ọ na-ebelata ibu igwe nke akụrụngwa, na-eme ka ọrụ akụrụngwa dịkwuo mfe, ma na-eme ka ntinye nke pipelines na akụrụngwa ndị ọzọ dị elu ma dị anya.
3. Nguzogide okpomọkụ dị elu: O nwere ezigbo nkwụsi ike okpomọkụ na nhazi kristal pụrụ iche nke silicon carbide na-enye ya ohere iguzogide okpomọkụ dị elu, yana okpomọkụ sintering nke ruru 1350 ℃. Njirimara a na-eme ka mkpuchi silicon carbide na-eguzogide iyi iji nọgide na-arụ ọrụ kwụsiri ike ọbụlagodi na gburugburu okpomọkụ dị elu, na-enweghị mgbanwe ma ọ bụ mmebi n'ihi okpomọkụ dị elu, na-eme ka ọ dabara adaba maka ọnọdụ ụlọ ọrụ dị iche iche dị elu dị ka ígwè, ike na ụlọ ọrụ ndị ọzọ.
4. Nguzogide ncha: Silicon carbide nwere ihe ndị sitere na kemịkalụ kwụsiri ike ma nwee ike igosipụta ezigbo nguzogide ncha n'ihu ihe dị iche iche nke kemịkalụ. Ma ọ bụ n'ibugharị nke siri ike nke acidic na alkaline na mmepụta kemịkalụ ma ọ bụ n'ọhịa nke nchekwa gburugburu ebe obibi dịka ọgwụgwọ nsị mmiri, mkpuchi na-eguzogide iyi silicon carbide nwere ike ichebe akụrụngwa nke ọma, gbochie akụrụngwa ka ihe kemịkalụ ghara imebi, ma gbasaa ndụ ọrụ nke akụrụngwa.
5. Ike na-adịghị ike na mgbochi-static: Seramiki silicon carbide nwere ike ọ gaghị arụ ọrụ nke ọma, nke na-eme ka ha dabara adaba maka ngwa ndị nwere ihe achọrọ siri ike maka ọkụ eletrik kwụ ọtọ, dịka ebe a na-arụ ọrụ na-anaghị agbawa agbawa. N'ebe ndị a, ọkụ eletrik kwụ ọtọ nwere ike ibute nnukwu ihe mberede nchekwa, ọrụ mgbochi-static nke mkpuchi silicon carbide na-anaghị arụ ọrụ nwere ike igbochi mkpokọta ọkụ eletrik kwụ ọtọ ma hụ na nchekwa mmepụta dị.
6. Ọ dị mfe ịkpụ, nwee ike ịhazi akụkụ ndị buru ibu na ndị dị mgbagwoju anya: Enwere ike iji usoro dịka sintering mmeghachi omume hazie silicon carbide, nke na-enye ya nnukwu uru n'ịkpụ. Site na usoro a, enwere ike ịmepụta seramiiki buru ibu na seramiiki dị mgbagwoju anya. Nke a pụtara na n'agbanyeghị otú ụdị na nha nke akụrụngwa ahụ si dị iche, enwere ike ịhazi mkpuchi na-eguzogide iyi silicon carbide nke ọma iji gboo mkpa nke ngwa ọrụ mmepụta ihe dị iche iche.
Ihe mkpuchi na-eguzogide iyi silicon carbide egosila nnukwu uru n'ọrụ n'ọhịa ụlọ ọrụ n'ihi ọtụtụ uru ya. Site na mmepe na ọganihu nke sayensị ihe, a kwenyere na a ga-etinye ihe mkpuchi na-eguzogide iyi silicon carbide n'ọtụtụ ebe, na-enye nkwado siri ike maka ọrụ dị irè na nke kwụsiri ike nke mmepụta ụlọ ọrụ mmepụta ihe. Ọ bụrụ na ị nwere mmasị na ihe mkpuchi na-eguzogide iyi silicon carbide, biko nweere onwe gị ịkpọtụrụ anyị n'oge ọ bụla iji chọpụta ihe nzuzo ndị ọzọ gbasara seramiiki silicon carbide ọnụ.
