Abstract
The invention relates to a production method of a ground net grounding body protected by hot-dip galvanizing and coating in a coordinating manner, which belongs to the technical field of production and manufacture of the ground net grounding bodies. The production method is characterized in that dip plating and hot shaping are carried out on a single workpiece, and the coating is vertically downwards sprayed onto the workpiece which is in horizontal movement and flatly laid through a spray head; and the production method further comprises the following steps: forming, cleaning, hot-dip galvanizing, hot shaping for carrying out roughening treatment on the surface, passivating treatment, sweeping, cleaning and purifying with xylene solvent, spraying of the nano-carbon anti-corrosion conductive coating, and drying. The production method has the positive effects that the hot shaping is immediately carried out after the hot-dip galvanizing for producing the surface with roughened teeth and a complete passivating film, the purchased nano-carbon anti-corrosion conductive coating is used for spraying the surface, the thermal stability of a coating layer after the treatment can withstand 30KA/2s high current impact, the coating layer can not be burned or fall off, the saline-alkaline performance can pass through 10% NaCl immersion 720-hour test, and the adhesive force can achieve grade 1, thereby meeting the requirements on the performances of the compound anti-corrosion ground net grounding body; and the production method can realize bath production and meet the market demands.
Description
Technical field
Production, the manufacturing technology field of possession net earth electrode.
Background technology
The zinc-plated section bar of the general employing of the earth mat earth electrode of hot galvanizing and coating coordinating protection, the method production of the direct manual brushing paint in the coarse back of surface finish
Galvanizing surface is very smooth, and is very poor to ADHESION OF PAINTS power, therefore does coating at galvanizing surface and must polish to galvanizing surface, though polishing can obtain surface roughness, but destroys the passivating film of galvanizing surface, influences the anticorrosion life-span of zinc coat.Can not effectively bring into play the antiseptic property of the earth mat earth electrode of hot galvanizing and coating coordinating protection; On-the-spot ground surface roughness is difficult to reach requirement, and polishing produces dust polluting environment.
Summary of the invention
The present invention provide thermal stability bear 30KA/2s heavy current impact coating do not burn do not come off, salt tolerant alkalescence is good and the production method of a kind of earth mat earth electrode by hot galvanizing and coating coordinating protection of strong adhesive force.
The technical scheme that the present invention takes:
A kind of production method of the earth mat earth electrode by hot galvanizing and coating coordinating protection; Zinc-plated and the paint spay-coating that comprises workpiece; Its scheme is: the zinc-plated of workpiece is hot shaping before the immersion plating of single-piece independence, the passivation, and paint spay-coating is that shower nozzle is sprayed on the workpiece that moves horizontally tiling vertically downward; And operation is implemented according to the following steps:
1) the raw material coil of strip is sheared shaping,
2) remove surface irregularities and conventional clean,
3) hot galvanizing, the immersion plating of single-piece independence,
4) hot shaping: the two sides extruding of band tooth planing tool is done roughening treatment to the surface,
5) Passivation Treatment: soak workpiece by passivator, make the surface form the passivation protection film,
6) purging, xylene solvent clean, and surface of the work is purified,
7) airless spraying nano-carbon anticorrosion conductive coating: shower nozzle is sprayed on the workpiece that moves horizontally tiling vertically downward,
8) oven dry makes coarse iron plate or galvanized iron sheet surface coverage dry nano-carbon anticorrosion conductive coating layer,
9) packing,
10) warehouse-in.
Good effect after the embodiment of the present invention is:
Because workpiece is not to adopt many braidings to connect to drag the formula hot galvanizing; But the immersion plating of single-piece independence just can be made hot shaping and Passivation Treatment to the single-piece workpiece after the hot galvanizing immediately, makes the surface, both sides obtain band tooth alligatoring and complete passivating film; It is big to have overcome cold polishing dust, contaminated environment; And with the nano-carbon anticorrosion conductive coating of outsourcing; Be sprayed on vertically downward on the surface of the work that moves horizontally tiling through the high-pressure airless spraying gun shower nozzle; Because workpiece is not vertically to hang spray, has avoided coating sagging vertically downward, has improved the surfacing and the thickness evenness of coating; Strong through handling like this back coating adhesion strength, thick coating, thermal stability stand 30KA/2s heavy current impact coating and do not burn and do not come off, and anti-corrosive properties are good; Soak 720 hours (one month) coatings through 10%NaCl and do not destroy, strong adhesion, adhesive force reach 1 grade, have satisfied composite anti-corrosive earth mat earth electrode performance requirement; Because above technological operation improves, just feasible can continued operation, produce by batch, meet the need of market.
