Gutegura Ikoranabuhanga rya Alumina Ceramics (1)

Gutegura ifu

Ifu ya Aluminaitegurwa mubikoresho byifu ukurikije ibicuruzwa bitandukanye bisabwa hamwe nuburyo butandukanye bwo kubumba.Ingano yifu yifu iri munsi ya 1 mm.Niba ari ngombwa gukora ibicuruzwa byiza bya alumina byera ceramic, usibye ubuziranenge bwa alumina bigomba kugenzurwa muri 99,99%, bigomba no gukora inzira yo gusya ultrafine kugirango ibice byayo bigabanye kimwe.

Mugihe ukoresheje ibishushanyo mbonera cyangwa inshinge, binder na plastike bigomba kwinjizwa muri poro, mubisanzwe mubipimo byuburemere bwa 10-30% bya plastiki ya termoplastique cyangwa resin, binder organic igomba kuvangwa nifu ya alumina kubushyuhe bwa 150-200,, murwego rwo koroshya imikorere.

Ibikoresho by'ifu byakozwe muburyo bwo gukanda bishyushye ntibikeneye kongeramo binder.Niba ikoreshwa rya kimwe cya kabiri cyikora cyangwa cyumye cyumye, hari ibisabwa byihariye bya tekiniki kuri poro, dukeneye gukoresha uburyo bwa spray granulation kugirango tuvure ifu, tuyigaragaze neza, kugirango tunonosore amazi yifu, byoroshye kuzuza urukuta rwibumba mu buryo bwikora.Gusasa granulation yifu isabwa mugihe cyo gukama, kandi inzoga za polyvinyl zitangizwa nka binder.Mu myaka yashize, ikigo cy’ubushakashatsi muri Shanghai cyashyizeho paraffine ikabura amazi mu rwego rwo guhuza imiti ya Al2O3, ifite amazi meza mu gushyuha.Ifu nyuma yo gutera spray igomba kuba ifite amazi meza, ubucucike bworoshye, gutemba Ubushyuhe bwo kugabanuka buringaniye buri munsi ya 30 ℃, igipimo cyiza cyingero zingana nibindi bihe, kugirango ubone ubwinshi bwicyatsi kibisi.

Uburyo bwo kubumba

Uburyo bwo kubumbaalumina ceramicshyiramo gukanda byumye, gutontoma, gukuramo, gukonjesha isostatike ikonje, gutera inshinge, gutemba, gukanda bishyushye no gukanda isostatike.Mu myaka yashize haba mu gihugu ndetse no hanze yarwo hanatejwe imbere gushungura igitutu, gushiramo inshinge, guterwa inshinge, gutera inshinge hamwe no gukoresha uburyo bwa tekinoroji.Imiterere itandukanye, ingano, imiterere igoye hamwe nibisobanuro byibicuruzwa bisaba uburyo butandukanye.
