Embodiment 1

[0015] Put 1Kg of water-quenched alloy with a nickel content of 67.25% in the synthesis kettle, pass in CO gas with a purity of not less than 99.9%, control the pressure in the synthesis kettle to 9Mpa, and the temperature to 240°C. Water-quenched alloy and carbon monoxide gas A selective carbonylation reaction occurs in the synthesis kettle for 48 hours to generate nickel carbonyl gas; the nickel carbonyl gas and CO are continuously fed into the decomposer at a ratio of 1:20, and the decomposition temperature is controlled at 250°C and the pressure is 0.02Mpa. The substrate is decomposed to form nickel foil. After the reaction, nitrogen gas is passed into the decomposer to replace and remove the undecomposed nickel carbonyl gas, and the nickel foil is obtained after peeling off. The specification of nickel foil is 0.02-0.1×100-400mm, the weight is 0.80Kg, and the purity is 99.0%;

Abstract

The invention provides a method for preparing a nickel foil, and relates to a method for preparing a nickel foil by adopting a carbonyl process. The method is characterized by comprising the steps: carrying out oxonation between nickel-containing water-quenched alloy as a raw material and carbon monoxide gas in a synthesizing kettle in the preparation process to prepare nickel carbonyl gas; and decomposing prepared nickel carbonyl gas in a decomposer, depositing decomposed nickel on a substrate suspended in the middle of the decomposer, cooling, discharging and stripping to obtain the nickel foil. By adopting a thermal decomposition manner to prepare the nickel foil, the components can be controlled, the cost is lowered, the environment is not polluted, and the prepared nickel foil is uniform in thickness.

Description

technical field [0001] A method for preparing nickel foil relates to a method for preparing nickel foil by a carbonyl method. Background technique [0002] Nickel foil is one of the basic materials used in electronics, telecommunications, instruments and other industries. Nickel foil has a high surface finish, good corrosion resistance and mechanical properties, and can be used as magnetic shielding, high energy storage density alkaline storage battery electrode skeleton, magnetic carrier, surface resistance, iron core, decorations, waterproof products and other materials, after treatment It can also be used as a new type of packaging material for fire prevention, moisture resistance and anti-magnetism. In recent years, with the development of industry, the demand for nickel foil, especially thin nickel foil, is increasing day by day, and nickel foil is developing in the direction of thin and wide. [0003] At present, the common methods of nickel foil production are rolli...
