A naghịzi eji nrụgide ikuku sintered silicon carbide dị ka ihe abrasive, kama ọ bụ ihe ọhụrụ, a na-ejikwa ya na ngwaahịa teknụzụ dị elu, dị ka seramiki nke ihe silicon carbide. Yabụ kedu uru isii dị na nrụgide ikuku na-eme ka silicon carbide na ngwa nke ceramik silicon carbide?
Uru isii nke ihe nrụgide ikuku sintered silicon carbide:
1. Njupụta dị ala
Ihe onwunwe carbide silicon nwere njupụta dị ala karịa metal, na-eme ka ngwaọrụ ahụ dị ọkụ.
2. Nguzogide corrosion
Ihe siliki carbide nwere ebe mgbaze dị elu, inertia kemịkalụ, nguzogide ujo, silicon carbide na-eji abrasives, ceramic kilns, silicon carbide blanks, enwere ike iji ya na ụlọ ọrụ na-agbaze na ụlọ ịgbaze na ọkụ ọkụ cylinder kwụ ọtọ, brik, aluminom electrolytic cell lining. , tungsten, obere ọkụ na ngwaahịa seramiiki silicon carbide ndị ọzọ.
3, okpomọkụ dị elu, ọnụọgụ mgbasawanye ọkụ na-ebelata
A na-arụpụta ihe siliki carbide na oke okpomọkụ. N'ebe ụfọdụ ọnọdụ okpomọkụ dị elu, ihe ndị chọrọ ike nhazi na nhazi nke ọma nke ceramik carbide silicon nwere ike nweta chọrọ. Igwe ọkụ dị elu nke silicon carbide dị ihe dị ka 800, na okpomọkụ nke ígwè bụ naanị 250. Ngụkọta siri ike, ọnụọgụ mgbasawanye ọkụ nke silicon carbide dị na 25 ~ 1400 bụ 4.10-6 / C. A na-atụle ọnụọgụ mgbasawanye thermal nke silicon carbide, na nsonaazụ ya na-egosi na ego ahụ dị ntakịrị karịa nke abrasives ndị ọzọ na ihe okpomọkụ dị elu. Silicon carbide gbanyere mkpọrọgwụ n'okpuru nrụgide ikuku
4, elu thermal conductivity
Thermal conductivity nke silicon carbide ihe dị elu, nke bụ akụkụ ọzọ dị mkpa nke ihe anụ ahụ nke silicon carbide. Thermal conductivity nke silicon carbide dị ukwuu karịa nke ndị ọzọ refractories na abrades, ihe dị ka ugboro 4 nke corundum. Silicon carbide nwere ọnụ ọgụgụ dị ala nke mgbasawanye thermal na ịdị elu thermal conductivity, yabụ, a ga-edobe workpiece na nrụgide dị ala n'oge kpo oku na jụrụ oyi. Nke a bụ ya mere akụrụngwa SiC ji eguzogide ujo.
5, ike igwe dị elu, isi ike dị mma
Ike igwe nke silicon carbide ihe dị oke elu, na-egbochi nrụrụ ihe. Silicon carbide nwere ike igwe dị elu karịa corundum.
6, elu ike ike na eyi iguzogide
Ihe siri ike nke silicon carbide dị oke elu, na ike nke Moss gap bụ 9.2 ~ 9.6, nke abụọ na diamond na tungsten carbide. E jiri ya tụnyere ihe nchara ọla, ọ na-enye ike siri ike, ọnụ ọgụgụ dị ala nke esemokwu, esemokwu dịtụ ala, obere ihe siri ike n'elu na nguzogide dị mma na-enweghị mmanu mmanu. Tụkwasị na nke ahụ, ọ na-eguzogide ihe ndị dị n'èzí, na-eme ka nkwụsị elu dị elu. Silicon carbide gbanyere mkpọrọgwụ n'okpuru nrụgide ikuku
Ngwa nke nrụgide ikuku sintered silicon carbide ceramik
1, silicon carbide ihe mmepụta nke ceramik pụrụ iche
Silicon carbide ihe onwunwe bụ ihe nwere nnukwu ike na ọnụ ala dị ọnụ ala, nke nwere ike ịmepụta ngwaahịa silicon carbide, dị ka silicon carbide seals, silicon carbide sleeves, silicon carbide bulletproof plates, silicon carbide profiles, wdg, nke nwere ike itinye n'ọrụ akàrà igwe na nfuli dị iche iche. Silicon carbide gbanyere mkpọrọgwụ n'okpuru nrụgide ikuku
2, mmepụta ihe nke zirconia nke ceramik pụrụ iche
Zirconia seramiiki nwere elu ionic conductivity, ezigbo kemịkalụ nkwụsi ike na nkwụsi ike nhazi, wee bụrụ ihe a na-amụ nke ọma ma jiri ya mee ihe. Site n'ịkwalite usoro mmepụta nke ihe nkiri electrolyte nke zirconia, na-ebelata okpomọkụ na-arụ ọrụ na ọnụ ahịa mmepụta nke ihe ndị a, na ịgbalịsi ike nweta mmepụta mmepụta ihe bụkwa ntụziaka dị mkpa nke nyocha n'ọdịnihu.
