Calcined alumina
Calcined alumina bụ a azụmahịa alumina ma ọ bụ Aluminium oxide. Ọ dị ọcha ntụ ntụ. Otu n'ime ihe ndị pụtara ìhè e ji mara Calcined alumina bụ ya ekweghị ekwe nke bụ 9 on mohs n'ike. E nwere osisi na ulo oru ubi nke ngwa maka ụdị alumina na ọnụ ọgụgụ nke pụrụ iche na klas na-emepụta izute dị iche iche na mkpa.
Identification nke akara ule
1) Calcined Aluminium S-100 akara ule: White granular free etoola powder agabiga 150 m.
2) Calcined Aluminium S-300 ọkwa: White ọkasị mma powder aga ezie 45 micron.
3) Calcined alumina SCM ọkwa: Ọ bụ akpatre ground akara ule esịnede kpamkpam nke superfine-agabiga 45 micron.
4) Calcined alumina S-300 pt: Ọ na-finely ground ọkwa esịnede kpamkpam nke ọkasị mma na n'elu mesoo.
Eji
Iji dị ka a eji ehi ura ihe onwunwe ke okpomọkụ omume nke pụrụ iche alloy steels, Ọ bụ iji dị ka a fluxing ajụ na nzukọ pụrụ iche steels ka a akụrụngwa nke ala mgbasa iko. Ọ na-eji dị ka a constituent nke pụrụ iche china dazes & ọ bụ iji dị ka a akụrụngwa n'ihi na imewe nke eze porcelains. Ọ bụ iji maka refractory ngwa dị ka eletriki insulators. Ọ bụ iji dị ka a abrasive eguzogide ọgwụ. Ọ bụ iji gbazere agbaze seramiiki taịl nile.
1. alumina polishing ntụ ntụ bụ na-acha ọcha crystalline powder esịnede a-alumina. Ọ nwere ike nweta ezi urughuru size nkesa na ekweghị ekwe site pụrụ iche na-achịkwa nhazi izute mkpa nke a dịgasị iche iche nke polishing ngwa.
2. The ngwaahịa nwere edo urughuru size, elu ekweghị ekwe, ike egweri ike, ngwa ngwa polishing ọsọ, elu arụmọrụ, na elu na ihie.
3. Ọ na-atụmatụ warara urughuru size nkesa nso, elu-egweri arụmọrụ, ezi polishing mmetụta, na elu na-egweri arụmọrụ nnọọ elu karịa nke silica ndị ọzọ soft Abrasives. The elu imecha bụ mma karịa polishing mmetụta nke na-acha ọcha corundum. Na a siri ike ọnwụ ike, na ngwa ngwa luster ọbọ ọsọ, ọ nwere ike isi nweta edo na-egbuke egbuke luster.
