Embodiment 1

[0032] A process for galvanizing the surface of a cable tray, comprising the following steps:

[0033] (1) One-time derusting: Soak the bridge frame in an acidic solution for 20 minutes, lightly brush the surface of the bridge frame with a soft brush, and stir the acidic solution to make the surface of the bridge frame have a uniform metallic luster;

[0034] (2) One-time cleaning: put the bridge frame after primary derusting into degreasing cleaning agent and soak at 40°C for 40 minutes, and irradiate the bridge frame with ultraviolet lamp for 5 minutes after soaking;

[0035] (3) Second cleaning: soak the bridge frame after the first cleaning in the biologically active acid solution for 30 minutes;

[0036] (4) Secondary derusting: put the bridge frame after secondary cleaning into the acidic solution for 15 minutes, and keep stirring the acidic solution during soaking;

[0037] (5) Three times of cleaning: wash the surface of the bridge frame after the second derusting wit...

Embodiment 2

[0043] A process for galvanizing the surface of a cable tray, comprising the following steps:

[0044] (1) One-time derusting: Soak the bridge frame in an acidic solution for 30 minutes, lightly brush the surface of the bridge frame with a soft brush, and stir the acidic solution to make the surface of the bridge frame have a uniform metallic luster;

[0045] (2) One-time cleaning: put the bridge frame after primary derusting into the degreasing cleaning agent and soak it at 50°C for 50 minutes, and irradiate the bridge frame with ultraviolet lamp for 10 minutes after soaking;

[0046] (3) Second cleaning: soak the bridge frame after the first cleaning in the biologically active acid solution for 40 minutes;

[0047] (4) Secondary derusting: put the bridge frame after secondary cleaning into the acidic solution for 20 minutes, and keep stirring the acidic solution during immersion;

[0048] (5) Three times of cleaning: wash the surface of the bridge frame after the second der...

Embodiment 3

[0057] A process for galvanizing the surface of a cable tray, comprising the following steps:

[0058] (1) One-time derusting: Soak the bridge frame in an acidic solution for 25 minutes, lightly brush the surface of the bridge frame with a soft brush, and stir the acidic solution to make the surface of the bridge frame have a uniform metallic luster;

[0059] (2) One-time cleaning: Put the derusted bridge frame into the degreasing cleaning agent and soak it at 45°C for 45 minutes, and then irradiate the bridge frame with ultraviolet lamp for 8 minutes after soaking;

[0060] (3) Second cleaning: soak the bridge frame after the first cleaning in the biologically active acid solution for 35 minutes;

[0061] (4) Secondary derusting: put the bridge frame after secondary cleaning into the acidic solution for 18 minutes, and keep stirring the acidic solution during immersion;

[0062] (5) Three times of cleaning: wash the surface of the bridge after the second derusting with 4°C h...

Abstract

The invention discloses a cable bridge surface galvanization process, and relates to the field of cable bridge processing. The cable bridge surface galvanization process comprises primary rust removal, primary cleaning, secondary cleaning, secondary rust removal, ternary cleaning, galvanization, airing, passivation and secondary airing; in primary rust removal, acid solution is used for dipping; in primary cleaning, a degreasing cleaning agent is used for cleaning; in secondary cleaning, biological active acid is used for cleaning; in ternary cleaning, high-pressure water currents are used forcleaning; a mechanical galvanization method is adopted to galvanize the surfaces of bridges, and the galvanization thickness is 52-58 microns; the damp resistance of galvanized cables is improved; and plated layers are not easy to damage, and are firmly combined with the bridges, so that the bridges are longer in service life.

Description

Technical field: [0001] The invention relates to the field of cable bridge processing, in particular to a surface galvanizing process of a cable bridge. Background technique: [0002] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Insulating covering. The cable has the characteristics of internal electrification and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. [0003] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are c...
