Silicon carbide seramiiki mandrel bụ ihe nwere ụdị mkpara ejiri ihe seramiiki silicon carbide mee. Silicon carbide seramiiki mandrel nwere ọmarịcha anụ ahụ na kemịkalụ ma na-ejikarị ya na mpaghara ụlọ ọrụ mmepụta ihe n'okpuru oke okpomọkụ, nrụgide dị elu na gburugburu gburugburu.
Silicon carbide bụ ụdị ceramik ọhụrụ nwere arụmọrụ dị oke ọnụ yana akụrụngwa akụrụngwa mara mma. N'ihi njirimara dị ka ike dị elu na ike siri ike, oke okpomọkụ na-eguzogide, nnukwu okpomọkụ conductivity na chemical corrosion resistance, Silicon Carbide nwere ike ọ fọrọ nke nta ka ọ ghara iguzogide ọgwụ niile. Ya mere, a na-eji SiC eme ihe na ngwuputa mmanụ, kemịkalụ, igwe na ikuku, ọbụna ike nuklia na ndị agha nwere ihe ha chọrọ na SIC.

Na okpomọkụ ruo 1400 ℃, SiC nwere ike ịnọgide na-enwe ike ya
N'ihi kemịkalụ ya na nkwụsi ike anụ ahụ, SiC nwere ike siri ike na nguzogide corrosion.
Isi atụmatụ:
1. Nkwụsi ike dị elu: Silicon carbide ceramic mandrel nwere ike ịnọgide na-enwe nkwụsi ike nke nhazi ya na ịrụ ọrụ na gburugburu ebe okpomọkụ dị elu. Ọ nwere ike iguzogide oke okpomọkụ dị oke elu ma nwee ezigbo nguzogide okpomọkụ, nke kwesịrị ekwesị maka ngwa na usoro okpomọkụ dị elu na akụrụngwa.
2. Nguzogide corrosion: Silicon carbide ceramic mandrel nwere ezigbo nguzogide corrosion ma nwee ike iguzogide mmebi nke acid, alkalis, ihe mgbaze na ụfọdụ mgbasa ozi na-emebi emebi. Ọ gaghị emeghachi omume na kemịkalụ ma ọ bụ mebie ya na gburugburu ebe na-emebi emebi, na-ejigide arụmọrụ mbụ ya na nkwụsi ike ya.
3. Yiri nkwụsi ike: Silicon carbide ceramic mandrel nwere oke isi ike ma na-eyi nkwụsi ike, ma nwee ike ịnọgide na-enwe ọnụ ọgụgụ dị ala n'okpuru nnukwu ọsọ na nnukwu esemokwu. Nke a na-eme ka ọ nwee ogologo ndụ na ntụkwasị obi na gburugburu ebe obibi siri ike.
4. Ọrụ mkpuchi dị mma: Silicon carbide ceramic mandrel nwere arụmọrụ mkpuchi dị mma ma nwee ike inye nchebe mkpuchi a pụrụ ịdabere na ya n'okpuru nnukwu voltaji na ọnọdụ ọkụ eletrik dị elu. A na-eji ya eme ihe na akụrụngwa voltaji dị elu na ihe mkpuchi mkpuchi na mpaghara nke ike, eletrọnịkị na semiconductor.
5. Dị arọ na ike dị elu: Silicon carbide ceramic mandrels nwere obere njupụta na ike dị elu, ma nwee ihe ndị dị mma na-arụ ọrụ. Ha nwere nnukwu mgbada na ike nkwụsịtụ ma nwee ike iguzogide nrụgide dị elu na nrụgide ígwè ọrụ.
