[0002] A sign is a sign indicating the direction, also called a billboard, a sign, such as a toilet pointing sign, a road sign, etc., can be called a sign. The corrosion resistance during use is relatively poor, and the sign is prone to discoloration and damage when it is used outdoors for a long time
[0003] At present, there are still some deficiencies in the existing aluminum alloy signs, for example, the hardness, wear resistance, corrosion resistance and oxidation resistance of the existing aluminum alloy signs are relatively general during use, and the signs are The probability of deformation and damage is prone to occur during use, which shortens the service life of the sign, and the primer and topcoat sprayed on the existing aluminum alloy sign have poor weather resistance and corrosion resistance, and the sign is used for a long time. Paint peeling and discoloration are prone to occur when used outdoors, reducing the clarity of information displayed on the sign

Embodiment 1

[0038] The anti-corrosion surface treatment process of the aluminum alloy sign, the treatment steps are as follows:

[0039]a. First, cut the installation size of the aluminum alloy base material. The motor speed of the cutting process is 2500-3000r / min to form the blank of the sign, and then polish and polish the blank of the sign after cutting. The speed of the motor is 1800-2000r / min, the thickness of polishing and grinding is 0.3-0.5mm, and the sign is obtained;

[0040] b. After step a is completed, heat-treat the polished and polished signboard;

[0041] c. After step b is completed, conduct ion nitriding treatment on the indicator board after heat treatment. First, connect the furnace body to the anode, and the indicator board to the cathode. N 2 The gas undergoes a brilliant discharge to become positive ions, which move to the working surface. In an instant, the cathode voltage drops sharply, causing the positive ions to rush to the cathode surface at high speed, con...

Abstract

The invention discloses an anti-corrosion surface treatment process for an aluminum alloy indication board. The process comprises the following treatment steps that a, firstly, an aluminum alloy base material is cut according to the mounting size, the rotating speed of a cutting motor is 2500-3000r / min, an indication board blank is formed, then polishing and grinding are carried out on the cut indication board blank, the rotating speed of a polishing and grinding motor is 1800-2000r / min, the polishing and grinding thickness is 0.3-0.5mm, and the indication board is obtained; b, after step a is completed, the polished and ground indication board is subjected to heat treatment; and c, after step b is completed, ion nitriding treatment is carried out on the indication board subjected to heat treatment, firstly a furnace body is connected with an anode, the indication board is connected with a cathode, and hundreds of volts of direct-current voltage is introduced between the anode and the cathode. After the indication board is subjected to corrosion resistance treatment, the hardness, wear resistance, corrosion resistance and oxidation resistance of the indication board in the using process are effectively enhanced, the probability of deformation and damage of the indication board in the using process is reduced, and the service life of the indication board is prolonged.

Description

technical field [0001] The invention relates to the technical field of sign treatment, in particular to an anti-corrosion surface treatment process for an aluminum alloy sign. Background technique [0002] A sign is a sign indicating the direction, also called a billboard, a sign, such as a toilet pointing sign, a road sign, etc., can be called a sign. The corrosion resistance during use is relatively poor, and the sign is prone to discoloration and damage when it is used outdoors for a long time. [0003] At present, there are still some deficiencies in the existing aluminum alloy signs, for example, the hardness, wear resistance, corrosion resistance and oxidation resistance of the existing aluminum alloy signs are relatively general during use, and the signs are The probability of deformation and damage is prone to occur during use, which shortens the service life of the sign, and the primer and topcoat sprayed on the existing aluminum alloy sign have poor weather resist...
