Description
Technical field
The present invention relates to steel plate processing technique field more particularly to a kind of processing methods of high durable PCM plate.
Background technique
PCM plate refers to color coated steel sheet, and color coated steel sheet is a kind of steel plate with organic coating, currently, coastal area is wet
Hot weather brings serious atmospheric corrosion effect to steel product, to improve corrosion resistance of steel, mainly has increase to close at present
Gold element and the big approach of external coating corrosion-inhibiting coating two, it is exactly stainless steel that the former is most widely used, and the latter is then with various zinc-plated
Plate, zinc-plated aluminum composite plate, paint precoating plate are representative.Zinc coat and the paint of coating are inherently by with resistant material
As insulating surface, perishable base protection is got up.The alloying element added in stainless steel is more expensive, causes stainless steel
Cost be ordinary carbon steel two to more than three times, limit its scope of application.Common galvanized sheet and coating galvanized sheet be not compared to
Rust steel has higher corrosion resistance for cheap price and opposite general steel plate, home appliance panel, in terms of
It is widely applied.But the more demanding place of some severe corrosion resistances of climatic environment, such as decoration panel peculiar to vessel, automobile
Plate, container plate etc., the galvanized sheet of common coating are not available since service life is too short then, it is therefore necessary to develop one kind
Corrosion resistance and good, cost and the close steel plate of common galvanized sheet.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of processing methods of high durable PCM plate, so that
Processing obtained PCM plate has superior corrosion resistance and long service life.
The technical solution adopted by the present invention to solve the technical problems are as follows:
A kind of processing method of high durable PCM plate, comprising the following steps:
Step 1: weather-resistant steel plate substrate pre-processes, weather-resistant steel plate is cut into required specification, and be washed into required shape,
To weather-resistant steel plate surface clean and dry；
The processing Step 2: weather-resistant steel plate quickly gets rusty makes weather-resistant steel plate by hair rust sink, and sink temperature stablizes 45 ~
50 degrees Celsius, apply the ac pulse voltage of 500V in weather-resistant steel plate upper and lower surface；
Step 3: high pressure water is to weather-resistant steel plate except floating rust, and polishing roll polishes weather-resistant steel plate upper and lower surface, then except floating rust
It cleans and uses hot-air blowing；
Step 4: roller coating back paint, priming paint, in weather-resistant steel plate upper and lower surface difference roller coating priming paint and back paint, and are put into solidification
Then drying in furnace water cooling treatment and uses hot-air blowing；
Step 5: roller coating finishing coat, the roller coating finishing coat again on the prime coat of weather-resistant steel plate, then at water cooling treatment and hot wind
Reason, obtains finished product.
As an improvement of the above technical solution, in step 3, after floating rust, on-line measurement weather-resistant steel plate surface hardness,
Compare measured value and standard value, by the pulse width in PID controller feedback regulation step 2, so that steady on weather-resistant steel plate
Determine rusty scale thickness and reaches 20 ~ 50um.
As an improvement of the above technical solution, in step 3, polished surface roughness Ra < 1.6 um.
As an improvement of the above technical solution, in step 4, priming paint is epoxy resin coating, and base coat thickness is 10 ~ 15um,
Back paint is with a thickness of 10 ~ 15um.
As an improvement of the above technical solution, in step 5, finishing coat is with a thickness of 20 ~ 30um.
The beneficial effects of the present invention are as follows:
Pretreated weather-resistant steel plate is carried out processing of quickly getting rusty by this processing method simple process, and high pressure water is except floating rust
Exposing surface stablizes rusty scale, which has the features such as high with substrate bond strength, coating performance is good, can prevent corrosion layer into
The extension of one step, and service life is very long.
Specific embodiment
A kind of processing method of high durable PCM plate of the invention, comprising the following steps:
Step 1: weather-resistant steel plate substrate pre-processes, weather-resistant steel plate is cut into required specification, and be washed into required shape,
To weather-resistant steel plate surface clean and dry；
The processing Step 2: weather-resistant steel plate quickly gets rusty makes weather-resistant steel plate by hair rust sink, and sink temperature stablizes 45 ~
50 degrees Celsius, apply the ac pulse voltage of 500V in weather-resistant steel plate upper and lower surface；
Step 3: high pressure water is to weather-resistant steel plate except floating rust, and polishing roll polishes weather-resistant steel plate upper and lower surface, then except floating rust
It cleans and uses hot-air blowing；
Step 4: roller coating back paint, priming paint, in weather-resistant steel plate upper and lower surface difference roller coating priming paint and back paint, and are put into solidification
Then drying in furnace water cooling treatment and uses hot-air blowing；
Step 5: roller coating finishing coat, the roller coating finishing coat again on the prime coat of weather-resistant steel plate, then at water cooling treatment and hot wind
Reason, obtains finished product.
Specifically, polished surface roughness Ra < 1.6 um；Priming paint is epoxy resin coating, and base coat thickness is 10 ~ 15um, back
Paint is with a thickness of 10 ~ 15um, and finishing coat is with a thickness of 20 ~ 30um.
In addition, after floating rust, on-line measurement weather-resistant steel plate surface hardness compares measured value and standard value in step 3,
Current density is controlled by PID controller, the pulse width in further feedback regulation step 2, to change on weather-resistant steel plate
Stablize rusty scale thickness, is finally reached and reaches 20 ~ 50um.
Weathering steel is a kind of low-alloy steel that the elements such as a certain amount of copper, phosphorus, chromium, nickel are added in common steel grade, due to
Master to be added is that copper, P elements and content are lower, and cost differs smaller with ordinary carbon steel, but by initial stage and common carbon
After the identical corrosion surface corrosion process of steel, weather-proof steel surface to form one layer since copper P elements are enriched with and stablize fine and close amorphous state
Rusty scale tissue, and combine closely with substrate, so that corrosion layer be prevented to further expand, common weather-resistant steel plate need to pass through spontaneous corrosion
Just start to generate stable anticorrosion layer after certain thickness, household appliances higher for appearance requirement can not be used directly, resistance to
It waits PCM plate to stablize by pre-oxidation rusty scale without the coating that derusts again, and rusty scale is stablized, service life is not less than 30 years, also
Have the characteristics that coating performance is good.
The above, only better embodiment of the invention, but the present invention is not limited to above-described embodiments, as long as
The technical effect of the present invention is achieved by any identical or similar means for it, all should belong to protection scope of the present invention.
