COMPUTER KEYBOARD WHICH RADIATES MINUS ION

摘要

The present invention relates to a computer keyboard, especially the synthetic SiO ₂ 35 to 55 wt%, ZrO ₂ 20 ~ 35 wt%, Ce ₂ O ₃ 15 ~ 20 wt%, Fe ₂ O ₃ 5 ~ 10 wt%, Al ₂ O ₃ consisting of 5 to 10% by weight and a coloring agent 0.2 to 1.0% by weight powder 99.5% by weight ratio: 0.5 to 65: 35, by molding a blend, to remove heavy metals and waste products accumulated in the skin and activate skin cells, slow aging, as well as smooth blood circulation and anion antibacterial action is emitted on the computer keyboard and a method of manufacturing the same. ; The invention SiO ₂ 35 ~ 55 wt%, ZrO ₂ 20 ~ 35 wt% , Ce ₂ O ₃ 15 ~ 20 wt%, Fe ₂ O ₃ 5 ~ 10 wt%, Al _{mixture 2} O ₃ 5 to 10% by weight and a coloring agent, and 0.2 to 1.0% by weight; And the mixed material melted in the melting furnace to a temperature of 1200 ~ 1350 ; After solidifying the molten material the screen for 12 hours and pulverized to a powder; Mixing the ceramic powder in a predetermined ratio by the resin in the liquid phase, and is manufactured by molding in a molding machine.
