1. Waa maxay ciidda dhoobada ah?
Ciidda dhoobada ayaa inta badan laga sameeyaa macdano ay ku jiraan Al2O3 iyo SiO2 waxaana lagu daraa walxo kale oo macdan ah.Ciid aasaasi ah oo wareegsan oo lagu sameeyay budada, pelletizing, sintering iyo hababka darajooyinka.Qaab dhismeedkeeda ugu weyn waa Mullite iyo Corundum, oo leh qaab hadhuudh wareegsan, refractoriness sare, xasilloonida heerkulbeegga wanaagsan, balaadhinta kulaylka hooseeya, saamaynta iyo iska caabbinta abrasion, sifooyinka kala qaybsanaan xoog leh.Ciidda dhoobada waxaa loo isticmaali karaa in lagu soo saaro shubid tayo sare leh nooc kasta oo ah hababka shubista ciidda.
2. Meesha codsiga ee ciidda dhoobada ah
Ciidda dhoobada ayaa si caan ah loogu isticmaalay aasaaska noocyada teknoolajiyada aasaasiga ah, sida ciid dahaarka leh, habka is-adkeysi (F NB, APNB iyo Pep-set), sanduuqa qabow, sanduuqa kulul, ciid daabacaadda 3D, iyo habka xumbo lumay. .
3. Tilmaamaha ciidda dhoobada
SND waxay bixin kartaa ciid dhoobo ah oo tilmaamo kala duwan leh.Halabuurka kiimikada, waxaa jira aluminium-oxide sare, ciid aluminium-oxide dhexdhexaad ah iyo ciid aluminium-oxide hoose ah, kuwaas oo u isticmaala ka hortagga walxaha kala duwan.Dhammaantood waxay leeyihiin qaybinta cabbirka walxaha kala duwan si loo qanciyo baahida macaamiisha.
