Description
Technical field
The present invention relates to spraying technology field, in particular to cleaning material in a kind of metal works spraying process and its make
Use method.
Background technique
Powder spray is the surface with powder spray coating device powder paint to workpiece, under electrostatic interaction, powder
It can be uniformly adsorbed in workpiece surface, form 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 generally carries out in powder spray room.Chinese patent (publication number: CN203044282U, publication date:
On July 10th, 2013) it points out, the spray gun in powder spray room with pulverized powder and the pendant for installing workpiece.Wherein, it sprays
Rifle and pendant can move, to guarantee that the surface of workpiece forms uniform coating.Spraying for vestibule profile, pendant include
Drive beam and the single hook on drive beam, vestibule profile are generally linked up with by c-type and are connected, then will linked up with by c-type
The both ends of the vestibule profile of connection are hung on single hook, so that vestibule profile is distributed from high to low in the vertical direction,
Wherein, spray gun generally moves along the vertical direction, and drive beam is moved along the length direction of vestibule profile.
When powder spraying chamber dust operation, the powdery paints to suspend in air is easy to be adsorbed to chamber interior walls of dusting,
When colour changing spraying, being adsorbed on the indoor powdery paints that dusts can be mixed to the powdery paints of new color, and workpiece is caused to spray
Powder colour developing is abnormal, influences the quality dusted, therefore is the appearance for avoiding above situation, when needing colour changing, need to carry out to powder spraying chamber
Cleaning, common way are by manually stepping into the efficiency cleared up using hairbrush, extension knife etc. in powder spraying chamber, but cleared up
It is low, the time very is expended, when influencing the working efficiency that dusts of powder spraying chamber, while being cleared up using scraper powder spraying chamber, is scraped
Knife is easy to increase the roughness for the chamber surface that dusts, and when leading to subsequent dust, powdery paints is easier to be adsorbed in the inner wall 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.

Workpiece described above includes the metal products such as bed board item, goods carrier, toast rack.
The experimental result of three above embodiment is as shown in table 3:
Table 3
From the experimental result in table 3 it is found that when being cleared up using tools 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 process provided by the invention
In cleaning material when, not by workpiece absorb powdery paints, there is 95% or more can be recycled.This is because using
When the tools such as conventional bristle brush and scraper clear up powder spraying chamber, it is easy to generate scratch 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 process provided by the invention is used, the component B of clean membrane material is applied
It is overlying on coarse component A coating film surface, forms smooth component B coated film, the powdery paints not absorbed by workpiece is only
There is sub-fraction to be adsorbed in the surface of component B coated film, the powder coating without being adsorbed in component B coating film surface
With recycling and reusing.
When being cleared up using tools such as conventional bristle brush and scrapers powder spraying chamber, with the increase of clearing times, powder spraying chamber
The roughness of inner wall is increasing, and the powdery paints of chamber interior walls of dusting absorption is more and more, is increasingly difficult to clear up, therefore,
Repeatedly when replacement paint color, the powdery paints newly sprayed is easy to be easy to be mixed in the powdery paints for being adsorbed in chamber interior walls of dusting
Together, it causes finished work surface to have mottle, influences product quality.And it is provided by the invention in chamber surface spraying of dusting
When cleaning material in metal works spraying process, then phenomenon appearance is not had.
When the chamber surface that dusts sprays the cleaning material in metal works spraying process provided by the invention, when needing replacing
When paint color, when due to using the modes such as inflate or pour water to clear up clean membrane material, it is only necessary to the time of half an hour, clearly
It is sustainable to use two weeks after reason；And when the tools such as conventional drag and hairbrush being used to clear up powder spraying chamber, cleaning needs every time
Two hours, and after cleaning, it is only sustainable to use one week.It can be seen that spraying spray provided by the invention in chamber interior walls of dusting
When the clean membrane material that powder room is convenient to clean, working efficiency can be greatly improved.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
