    摘要: Provided is a forming method of a metal layer suitable for a 3D printing process. The method includes the steps of providing a plurality of metal particles on a substrate; applying an oxide-removing agent to the metal particles to remove metal oxides on the metal particles; at a first temperature, performing a first heat treatment on the metal particles for which the metal oxides are removed to form a near shape; and at a second temperature, performing a second heat treatment on the near shape to form a sintered body. The first temperature is lower than the second temperature.

    摘要: Provided is a forming method of a metal layer suitable for a 3D printing process. The method includes the steps of (1) providing first metal particles on a substrate to form a first layer; (2) performing a first pre-heat treatment on the first layer; (3) applying an oxide-removing agent on selected first metal particles in the first layer to remove metal oxides; (4) providing second metal particles on the first layer to form a second layer; (5) performing a second pre-heat treatment on the second layer; (6) applying the oxide-removing agent on selected second metal particles in the second layer to remove metal oxides; repeating (1) to (6) until a latent part is formed; performing a first heat treatment on the first and second metal particles of the latent part to form a near shape; and performing a second heat treatment on the near shape to form a sintered body.

    摘要: A fire-resistant polyurethane foam is provided. A hydroxyl-containing inorganic fire retardant is premixed with a polyisocyanate and a polyol, respectively, to form two premixtures. Then, the two premixtures are mixed for reaction to form a fire-resistant polyurethane foam. Preferably, a combination of different particle sizes of the fire retardant is employed to maximize the amount of the fire retardant and increase the fire resistance of the foam.
