Description
Technical field
The present invention relates to spraying technology field, cleaning material in more particularly to a kind of metal works spraying coating process and its make
Use method.
Background technology
Powder spray is the surface powder paint to workpiece with powder spray coating device, under electrostatic interaction, powder
Workpiece surface can be uniformly adsorbed in, forms the coating of powdery；Powdery coating solidifies by high-temperature baking, and it is different to become effect
The final coating of (different-effect of powder).
Powder spray is typically carried out in powder spray room.Chinese patent (publication number：CN203044282U, publication date：
On July 10th, 2013) point out, the spray gun in powder spray room with pulverized powder and the suspension member for installing workpiece.Wherein, spray
Rifle and suspension member can move, to ensure that the surface of workpiece forms uniform coating.Spraying for vestibule section bar, suspension member include
Drive beam and the single hook on drive beam, vestibule section bar are typically linked up with by c-type and connected, then will linked up with by c-type
The both ends of the vestibule section bar of connection are hung on single hook so that and vestibule section bar in the vertical direction is distributed from high to low,
Wherein, spray gun typically vertically moves, and length direction of the drive beam along vestibule section bar moves.
When powder spraying chamber dust operation, the powdery paints to be suspended in air is easily adsorbed to chamber interior walls of dusting,
When colour changing sprays, adsorbing the powdery paints in powder spraying chamber can mix to the powdery paints of new color, cause workpiece to spray
Powder colour developing is abnormal, influences the quality dusted, therefore is the appearance for avoiding the above situation, and when needing colour changing, powder spraying chamber need to be carried out
Cleaning, conventional way is to be cleared up by manually stepping into powder spraying chamber using hairbrush, extension knife etc., but the efficiency cleared up
It is low, the time is very expended, when influenceing the operating efficiency of dusting of powder spraying chamber, while powder spraying chamber being cleared up using scraper, is scraped
Knife easily increases the roughness for the chamber surface that dusts, and when causing subsequently to dust, powdery paints is easier to be adsorbed in the inwall of powder spraying chamber.
And also have the automatic cleaning apparatus that can be cleared up side plate at present, but such cleaning plant can not will be adsorbed in chamber interior walls of dusting
On powdery paints clean out completely.

The experimental result of three above embodiment is as shown in table 3：
Table 3
It was found from the experimental result in table 3, when being cleared up using instruments such as conventional bristle brush and scrapers powder spraying chamber, do not have
Only having 75% by the powdery paints that workpiece absorbs can be recycled；And use metal works spraying coating process provided by the invention
In cleaning material when, not by workpiece absorb powdery paints, there is more than 95% can be recycled.Because using
When the instrument such as conventional bristle brush and scraper is cleared up powder spraying chamber, scratch easily is produced in chamber interior walls of dusting, makes chamber interior walls of dusting
Roughness increase, in powder spraying chamber when being sprayed to workpiece, be not easily adsorbed at and dust by the powdery paints that workpiece absorbs
Chamber interior walls；And the cleaning material in metal works spraying coating process provided by the invention is used, the component B of clean membrane material is applied
Coarse first component coated film surface is overlying on, forms smooth component B coated film, not by the powdery paints of workpiece absorption only
There is the surface that sub-fraction is adsorbed in component B coated film, the powder coating without being adsorbed in component B coated film surface
With recycling.
When being cleared up using instruments such as conventional bristle brush and scrapers powder spraying chamber, with the increase of clearing times, powder spraying chamber
The roughness of inwall is increasing, and the powdery paints of chamber interior walls of dusting absorption is more and more, is increasingly difficult to clear up, therefore,
When repeatedly changing paint color, the powdery paints newly sprayed is easily easily mixed in being adsorbed in the powdery paints for chamber interior walls of dusting
Together, cause finished work surface to have mottle, influence product quality.It is and provided by the invention in powder spraying chamber surface spraying
During cleaning material in metal works spraying coating process, then phenomenon appearance is not had.
During cleaning material in powder spraying chamber surface spraying metal works spraying coating process provided by the invention, when needing to change
During paint color, during due to clearing up clean membrane material using inflation or the mode such as pour water, it is only necessary to the time of half an hour, clearly
It is sustainable to use two weeks after reason；And when being cleared up using instruments such as conventional drag and hairbrush powder spraying chamber, cleaning every time needs
Two hours, and after cleaning, it is only sustainable to use one week.As can be seen here, spray provided by the invention is sprayed in chamber interior walls of dusting
During the clean membrane material that powder room is convenient to clean, operating efficiency can be greatly improved.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
The present invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：Its according to
The technical scheme described in foregoing embodiments can so be modified, either which part or all technical characteristic are entered
Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention technology
The scope of scheme.
