Abstract
The invention discloses a method for machining a scaffold. The method comprises the following steps of: performing acid washing on the scaffold by using a special antirust agent so as to reduce the produced volatile hydrochloric acid mist; cleaning the acid-washed scaffold, coating a phosphate film on the surface of the scaffold, and then drying the scaffold, wherein the thickness of the phosphate film is 30 microns; performing molding powder electrostatic adsorption on the surface of the dried scaffold; and baking and painting to obtain the scaffold. In a spraying mode, an anti-corrosion layer covers the surface of a steel scaffold so as to obtain the scaffold which is stable in structure and high in corrosion resistance.
Description
Technical field
The present invention relates to a kind of scaffold, specifically the processing method of the scaffold of a kind of Stability Analysis of Structures, fine corrosion resistance.
Background technology
Scaffold refers to the job site for workman's operation and solves various supports vertical and that the level transportation is set up, is used in the higher place that can't directly construct of exterior wall, inside fitting or floor height in the construction site.Mainly work up and down for the workmen or the maintenance of peripheral safety net and high-altitude installation component etc.It is steel pipe or synthetic material etc. that the tradition scaffold is made material, and scaffold also extensively is used in departments such as advertising, municipal administration, traffic road and bridge, mines.But steel pipe gets rusty easily, and does not have corrosion resistance, and long-term the use do not have safety guarantee, and service life is short.
All parts of aluminium alloy scaffold adopt special aluminum alloy material, lighter by 75% than traditional steelframe, aluminium alloy fast-assembling scaffold solves enterprise's work high above the ground difficult problem, can satisfy the wall corner, the work high above the ground requirement at narrow space places such as stair is good assistants of enterprise's work high above the ground.But aluminium alloy scaffold price is high, and intensity is not as steel pipe.
Summary of the invention
In order to improve the corrosion resistance of scaffold, prolong the service life of scaffold, the purpose of this invention is to provide a kind of processing method of scaffold, this method adopts the mode of spraying, at steel scaffold surface coverage anticorrosive coat, obtain the scaffold of Stability Analysis of Structures, fine corrosion resistance.
The objective of the invention is to be achieved through the following technical solutions:
A kind of processing method of scaffold is characterized in that this method may further comprise the steps:
1) adopts special-purpose antirust agent that scaffold is carried out pickling, reduce the volatility hydrochloric acid acid mist that produces; The quality of described special-purpose antirust agent is formed: antirust agent 30-40%, concentration are 31% hydrochloric acid 70-60%.
2) scaffold after the pickling is cleaned up, cross phosphating coat on the scaffold surface, the thickness of phosphating coat is the 20-30 micron, oven dry; Bake out temperature is 40-60 ℃; Drying time is 15-20 minute.
3) the molding powder Electrostatic Absorption is carried out on the scaffold surface after oven dry; Obtain the molding powder film; The thickness of molding powder film is the 60-70 micron;
4) get scaffold behind the solid lacquer of baking, the temperature of the solid lacquer of baking is 220 ℃; Drying time is 30 minutes.
The present invention adopts special-purpose antirust agent that scaffold is carried out the degree of depth and cleans, and can reduce the volatility hydrochloric acid acid mist of generation.Cross one deck phosphating coat on the scaffold surface, carry out the molding powder Electrostatic Absorption after the oven dry again on the surface, adhesion is good, Stability Analysis of Structures, and fine corrosion resistance has prolonged service life of scaffold.
The scaffold that the present invention obtains is applicable to the occasion of seriously corroded.
The specific embodiment
A kind of processing method of scaffold, this method may further comprise the steps:
1) adopts special-purpose antirust agent that scaffold is carried out pickling, reduce the volatility hydrochloric acid acid mist that produces; The quality of special-purpose antirust agent is formed: antirust agent 40%, concentration are 31% hydrochloric acid 60%.
2) scaffold after the pickling is cleaned up, cross phosphating coat by the phosphatization liquid bath on the scaffold surface, the thickness of phosphating coat is 30 microns, oven dry; Bake out temperature is 40-60 ℃; Drying time is 20 minutes.
3) the molding powder Electrostatic Absorption is carried out on the scaffold surface after oven dry, obtains the molding powder film; Adopt spray gun to spray, the honeysuckle flower powdery paints that molding powder can adopt Nanjing honeysuckle flower synthetic material Products Co., Ltd to produce.The thickness of molding powder film is 70 microns
4) get scaffold behind the solid lacquer of baking, the temperature of the solid lacquer of baking is 220 ℃; Drying time is 30 minutes.
The present invention adopts special-purpose antirust agent that scaffold is carried out the degree of depth and cleans, and can reduce the volatility hydrochloric acid acid mist of generation.The scaffold that obtains, adhesion is good, Stability Analysis of Structures, fine corrosion resistance, long service life.
