Description
Technical field
The present invention relates to the removal field for being applied to coating for metal surfaces more particularly to a kind of metal surface protection UV ink
Device for removing scum, device for removing scum application method, and combined apparatus centered on device for removing scum and combination technique.
Background technique
So-called metal, as stainless steel alloy refers to the height that can be resisted atmosphere, weak erosive medium, strong corrosive media and corrode
Alloy steel grade and there is excellent corrosion resistance, mouldability, Environmental compatibility and the high intensity in very wide temperature range, height
The features such as toughness, so no matter in war industry, heavy industry, light industry, electrician trade, aerospace, ship or living
It is all had been widely used in the industries such as articles, building decoration.
Metal manufacture beginning needs to carry out melting-casting-hammer cogging-rolling-annealing-machine to numerous raw materials of metal
The treatment process such as tool processing-quenching could obtain final finished product, simple and smallclothes finished product is just straight often over simple packaging
It picks toward market；However big and complexity metalwork is needed by special transport or packing processes, this is frequent in the process
The problems such as colliding with, scratch, deforming of metal product can occur.More have for a long time without using person, idle metal often occurs
The problems such as burn into is denaturalized and lead to metal, such as the decline of mechanical property corrosion resistance performance, therefore would generally be in metal surface
It is armor coated, performance and the service life of metal material are maintained as far as possible, such as oil film, resin layer, ink solidification layer.
In addition, needing to remove the protective film of metallic substrate surface, the side of deprotection when needing using metal
Formula is more various, the method that the present invention only focuses on chemical demoulding, and chemical demoulding is that chemical solvent reacts with paint film, makes it
It dissolves or expands effect, and then paint film removal or paint film is allowed directly to fall off from substrate surface, can more efficiently remove
A kind of chemical mixture of substrate surface paint film, chemical depainting method is to be most commonly used for removing various metal surface paint films at present
Method.
If CN101139474A provides a kind of while efficiently stripping print circuit board surface green paint, will not damage
The green paint scavenger of printed wiring board has and strips that speed is fast, and the advantage that wastewater treatment is easy.In use, it uses first
It removes liquid medicine to soften ink, be completely exfoliated, the potassium hydroxide and liquid alkaline in component are to the oil in plank and hole
Ink, which rises, impregnates emollescence, is then removed using giant, described the prior art has the following problems: (1) remover
Substrate is not influenced, but giant there will obviously be apparent mechanical shock to influence on material, cause to deform；(2) after removing
Green paint direct emission, dangerous environmental protection.This processing mode also appears in CN106497213A, first will be to depainting workpiece
Surface and oil contaminant and Fouling Cleaning it is clean after, then be completely submerged in alkaline paint-removing liquid, treatment temperature is 25 DEG C -60 DEG C,
The processing time is 20 ± 10min, is taken out from alkaline paint-removing liquid after the completion of the processing of workpiece depainting, then by workpiece, and use clear water
The coating residue that its surface depends on is rinsed well；Workpiece is during cleaning, when its surface is difficult to clean, in heaped-up
Residue when, workpiece can clean residue by giant, the workpiece after cleaning further according to client demand into
Row next process, this rough processing mode are not that harmonious society is advocated.
In addition, a kind of polyester enamelled wire paint removing process provided such as CN105670375A Zhejiang University :(a) by paint stripper plus
Enter into lye tank (vat), and is heated to the paint film treatment temperature of polyester enamelled wire；(b) paint stripper in lye tank (vat) band is pumped into stir
Mix the depainting bucket bottom of paddle；Polyester enamelled wire to depainting is put into depainting bucket；(c) start to stir after overflow, revolving speed is every
30~300 turns of minute；The paint film to fall off flows into filter vat as paint stripper is from the overflow launder spilling at the top of depainting bucket； (d)
The paint film and paint stripper to fall off separates in filter vat, and paint stripper goes successively to lye tank (vat), described more excellent in the prior art
Part be to be filtered paint film, separate, but still remain following problem: (1) aqueous alkali is higher to containers demand, and de-
Film slot is open system, and paint stripper is readily volatilized or sputters；(2) paint film removed floats on above paint stripper, when workpiece is mentioned
Out when lye paint stripper slot, paint film still has great probability to be adhered to substrate surface, is necessarily required to the paint of secondary treatment adherency
Film.
Secondly, as CN103923770A discloses plastics adhesive layer cleaning agent, using the plastic cleaning technique of the cleaning agent
And cleaning equipment, after completing overburden operation, cleaning agent in reaction kettle is exported and is recycled after filtering；Then, by plastics
Fragment and adhesive layer overburden import in separating tank, according to plastic pieces density and the density of adhesive layer overburden, in separating tank
The separating liquid for adapting to concentration is inside put, separates plastic pieces up and down in separating liquid according to density difference with adhesive layer overburden,
Floating plastic pieces and sinking adhesive layer overburden or floating adhesive layer overburden and sinking plastic pieces are formed, although open
By different Density Separation overburdens, but not disclosing specific separating liquid, ink material is only to refer to a kind of separation
Mode, and entire complex process, higher cost.It to sum up states: at least there is following area for improvement in the prior art: (1)
The inefficiency of paint stripper is not easy to be completely exfoliated；(2) paint film processing after removing is inconvenient, not environmentally, be unfavorable for industrializing.
