摘要:
A ceramic-and-plastic composite includes a ceramic article, a nano-silicon containing coating bonded on a surface of the ceramic article, a glue layer bonded with the nano-silicon containing coating, and at least a plastic article bonded to the glue layer. The nano-silicon containing coating partially permeates into the ceramic article. An electronic device using the ceramic-and-plastic composite is also described.
摘要:
A surface treatment method for substrate includes: spraying liquid is provided, the spraying liquid includes silane coupling agent, leveling agent, isopropyl alcohol, ethanol, acetic acid and water; a substrate having a metallic coating disposed thereon is provided; the spraying liquid is sprayed on the metallic coating, and then spraying liquid is baked to form a transparent protecting layer on the metallic coating; and a painting layer is formed on the protecting layer. The housing formed by the surface treatment method is also provided.
摘要:
A housing includes a substrate made of aluminum or aluminum alloy, an anodic oxide film disposed on the substrate, and an abrasion resisting layer disposed on the anodic oxide film. The abrasion resisting layer is an alkylate silicon dioxide layer containing nano aluminum oxide powder. An electronic device using the housing is also described.
摘要:
A device for applying a magnetic field to a container comprises an adjustable magnetic field generator. The adjustable magnetic field generator is adjacent to the container and has a magnet having one magnetic pole adjacent a wall of the container and another magnetic pole away from the wall of the container. The adjustable magnetic field generator comprises a magnet. The intensity of magnetic field applied to the container gradually decreases from the container wall adjacent the magnetic pole of the magnet to the opposite container wall. Method for coloring anode coatings using the coloring device is also provided.
摘要:
A paint composition contains polyurethane paint and nano silicon dioxide. The weight percentage of the nano silicon dioxide in the paint composition is about 2% to about 10%. The surface of the nano silicon dioxide chemically bonds with a silane coupling agent having amino function groups or an aluminate coupling agent having amino function groups.
