Foda Alumina da aka yi wa allurar Platelet
An yi foda mai gogewa na faranti Calcined Alumina da ingantaccen foda na masana'antu a matsayin kayan aiki, kuma ana sarrafa shi ta hanyar wani tsari na musamman na samarwa. Siffar lu'ulu'u na foda mai gogewa na alumina da aka samar tana da siffar hexagonal mai faɗi kamar tabular, don haka ana kiranta da Platelet Alumina ko Tableular Alumina.
Alumina foda ce mai inganci ta alumina, wacce ta ƙunshi lu'ulu'u mai siffar faranti na Al2O3 mai tsarki sama da 99.0%. Tana da kyawawan halaye masu jure zafi da kuma rashin sinadarai, kuma ba ta lalacewa ta hanyar acid ko alkaline. Ganin cewa ana sarrafa rarrabawar Platelet Alumina sosai, tana iya samar da kyakkyawan saman da aka lanƙwasa, wanda hakan ke ba ta tasiri sosai a matsayin gogewa. Tare da amfani mai yawa, Platelet Alumina foda ce mai gogewa da za ta iya yin ayyuka da yawa.

Amfanin Alumina Foda
1. Idan aka kwatanta da sauran foda na tebur, foda na alumina na tebur yana da kyawawan halaye na haɗin kai. Kamar wurin narkewa mai yawa, ƙarfi mai ƙarfi, ƙarfin injina mai yawa, juriya mai kyau ga lalacewa, juriya ga sinadarai, juriya ga iskar shaka da juriya ga zafi da sauransu.
2. Siffar takardar da aka yi da lebur tana sa gogayya ta fi girma, tana inganta saurin niƙa da inganci, wannan zai iya rage yawan injunan niƙa, aiki da lokacin niƙa.
3. Siffar takardar da ba ta da faɗi ba ta sa niƙa abu ba ta da sauƙi, ƙimar samfuran da suka cancanta na iya ƙaruwa da kashi 10%-15%. Misali, ƙimar wafer silicon mai inganci na semiconductor zai iya kaiwa kashi 96% ko fiye.
4. Yana da tasirin nano da ƙananan foda, aikin saman yana da matsakaici, ba wai kawai yana iya haɗuwa da sauran ƙungiyoyi masu aiki yadda ya kamata ba, har ma ba shi da sauƙin tattarawa da sauƙaƙe watsawa mai tasiri.
5. Yana da kyakkyawan mannewa, babban tasirin kariya da kuma ikon nuna haske.
6. Foda mai siffar alumina kusan tana da haske, ba ta da launi, kuma tana da faɗi mai faɗi da santsi. Lu'ulu'u masu kyau masu siffar hexagons ne na yau da kullun.
7. Ana iya yin foda mai siffar alumina mai kyau ta hanyar amfani da tabular.
1. Masana'antar lantarki: niƙa da gogewa na wafers na silicon monocrystalline na semiconductor, lu'ulu'u na quartz, semiconductors masu haɗaka (gallium na kristal, nano na phosphating).
2. Masana'antar gilashi: niƙa da sarrafa gilashin lu'ulu'u, gilashin quartz, allon harsashi na gilashin kinescope, gilashin gani, gilashin nuni na ruwa (LCD), da kuma gilashin quartz.
3. Masana'antar shafa: shafa na musamman da kuma cikawa don fesawa ta plasma.
4. Masana'antar sarrafa ƙarfe da yumbu: kayan yumbu masu daidaito, kayan yumbu masu siminti, kayan shafa masu zafi mai ƙarfi, da sauransu.
