  • Publication number: 20220183299
    Abstract: The invention relates to Cu-embedded masterbatches forming by a novel formulation and its production process. The novel formulation comprises a mixing powder prepared from Cu2O and ZnO. The mixing powder is milled in water to form slurry. Spray-dry the slurry at 130˜150° C. to get anti-bacterial powder. Add 12 wt. %˜15 wt. % of the anti-bacterial powder to plastic masterbatches and follow by pre-mixing, heating, stirring, melting, extruding, cooling and cutting process to obtain the Cu-embedded masterbatches.

  • Publication number: 20220123277
    Abstract: A manufacturing method of a carbide includes steps as follows. A carbon source is provided, a contacting step, a heating step and an electrochemical step are performed. The carbon source includes an amorphous carbon and a compound. The compound is a chalcogen compound, a pnictide compound, a halide, a hydroxide or a salt of a metal or a metalloid. In the contacting step, the carbon source is disposed in an alkaline earth metal halide to form a reactant. In the heating step, the reactant is heated to form a heated reactant. In the electrochemical step, a current is applied to the heated reactant, wherein the current passes through the carbon source, so as to make the alkaline earth metal halide, the amorphous carbon and the compound react with one another to form a carbide of the metal or the metalloid.

  • Publication number: 20220118418
    Abstract: A manufacturing apparatus of carbide of the present disclosure includes a tank, a lid, a molten salt crucible, an electrode assembly, an air intake device and a heating device. The lid is connected to the tank to jointly delimit a compartment. The molten salt crucible is disposed in the compartment for containing a salt. The electrode assembly includes a working electrode and a counter electrode. An end of the working electrode and an end of the counter electrode both contact the salt in the molten salt crucible, and the end of the working electrode contacting the salt is for fixing a reactant tablet. The air intake device is configured to exchange the air in the compartment. The heating device is configured to heat the compartment.

  • Patent number: 8815633
    Abstract: A method of fabricating a 3-dimensional structure on a copper-indium-gallium-diselenide material comprises steps: preparing a CIGS (Copper Indium Gallium Diselenide) substrate, and defining two types of regions complementary to each other on the CIGS substrate; providing a mold absorbing an etching solution that can etch the CIGS substrate instead of the mold; aligning the mold to the two types of regions, and allowing the etching solution to flow out from the mold and contact with the two types of regions to etch the two types of regions for generating a level drop between the two types of regions and forming a 3-dimensional (3D) structure on the CIGS substrate. As a result, the present invention can fabricate a large-area 3D structure on a CIGS substrate rapidly without using expensive equipments or complicated processes.
