Abstract
The invention relates to a color steel plate processing method. The color steel plate processing method comprises the following steps of 1, steel plate treatment, 2, steel plate surface passivation treatment under the conditions of a passivating agent, a treatment temperature of 28-35 DEG C and treatment time of 3-5h, 3, by ammonium hydroxide with content of 5%, washing the surface of the steel plate treated by the step 2 and carrying out air drying to remove water on the surface, and 4, spraying priming paint on the steel plate treated by the step 3, drying the priming paint and spraying finish. The color steel plate processing method has simple processes, utilizes the novel passivating agent in steel plate surface passivation, has good treatment effects, produces a compact, uniform and fine passivated layer, and improves color plate corrosion resistance. The passivated layer produced by the color steel plate processing method has weak polarity and is conducive to surface coating so that a phosphorization process is avoided and color steel plate processing efficiency is improved.
Description
Technical field
The invention belongs to steel plate manufacture field, be specifically related to a kind of working method of color steel.
Background technology
The coat type of color coated steel sheet can be divided into polyester, silicon modified polyesters, polyvinylidene fluoride and plastisol.The condition of surface of color coated steel sheet can be divided into paint sheet, matrixes for embossing and printing plate, color coated steel sheet is widely used in industry such as building household electrical appliances and communications and transportation etc., steel-structure factory building is mainly used in for construction industry, airport, the roof wall surface of storehouse and the industry such as freezing and commercial building and door etc., color steel needs to carry out surface treatment before carrying out spray-on coating, to increase the corrosion resistance nature of steel plate and to spray the contact stability of rear coating and surface of steel plate, in present treatment process, first Passivation Treatment is carried out to steel plate, improve the antiseptic property of surface of steel plate, then bonderizing is carried out, conveniently spray treatment is carried out to surface of steel plate, complex process, processing cost is high.
Summary of the invention
The object of this invention is to provide a kind of working method of color steel, disposable process is carried out in the passivation of color steel and phosphatization, and processing efficiency is high, and treatment effect is even.
The present invention is achieved through the following technical solutions:
A working method for color steel, comprises the following steps:
(1), steel plate process, steel plate is cut into required specification, stamping machine is used to be washed into required shape, then surface of steel plate is used the sodium hydrogen carbonate solution cleaning surface of steel plate of 35-42 DEG C 8%, then hexane solution is used to clean, then surface of steel plate is dried, the greasy dirt of removing surface of steel plate and dust;
(2), surface of steel plate Passivation Treatment, passivator process is used at 28-35 DEG C, passivator is made up of following component by weight: potassium permanganate 8-15 part, potassium primary phosphate 5-7 part, diatomite 3-5 part, 45% sulfuric acid 3-5 part, water 15-20 part, after mixing, PH is adjusted to 4.5-6, the treatment time is 3-5h;
(3) surface of steel plate, by step (2) handled well uses the ammoniacal liquor cleaning of 5%, then dries the moisture on surface;
(4) the steel plate spray base, by step (3) handled well, after priming paint drying, topcoating.
Preferably, passivator is made up of following component by weight: 12 parts, potassium permanganate, potassium primary phosphate 7 parts, 3.5 parts, diatomite, 45% 4 parts, sulfuric acid, 16 parts, water, after mixing, PH is adjusted to 5.5.
Beneficial effect of the present invention: the working method technique of color steel provided by the invention simply especially uses new passivation agent in surface of steel plate Passivation Treatment process, treatment effect is good, passivation layer compacts, evenly fine and closely woven, improve the Corrosion Protection of color steel, meanwhile, the passivation layer after process has weak polarity, can be conducive to carrying out top coat operation, thus eliminate the step of phosphatization, improve the working (machining) efficiency of color steel.
Embodiment
A working method for color steel, comprises the following steps:
(1), steel plate process, steel plate is cut into required specification, stamping machine is used to be washed into required shape, then surface of steel plate is used the sodium hydrogen carbonate solution cleaning surface of steel plate of 35-42 DEG C 8%, then hexane solution is used to clean, then surface of steel plate is dried, the greasy dirt of removing surface of steel plate and dust;
(2), surface of steel plate Passivation Treatment, passivator process is used at 28-35 DEG C, passivator is made up of following component by weight: potassium permanganate 8-15 part, potassium primary phosphate 5-7 part, diatomite 3-5 part, 45% sulfuric acid 3-5 part, water 15-20 part, after mixing, PH is adjusted to 4.5-6, the treatment time is 3-5h;
(3) surface of steel plate, by step (2) handled well uses the ammoniacal liquor cleaning of 5%, then dries the moisture on surface;
(4) the steel plate spray base, by step (3) handled well, after priming paint drying, topcoating.
Preferably, passivator is made up of following component by weight: 12 parts, potassium permanganate, potassium primary phosphate 7 parts, 3.5 parts, diatomite, 45% 4 parts, sulfuric acid, 16 parts, water, after mixing, PH is adjusted to 5.5.
In the present invention, use the obtained passivator of potassium permanganate, potassium primary phosphate, diatomite, sulfuric acid allotment, because diatomite has good absorption property, the each stock dispersion of passivator can be made evenly, the thickness of process post passivation layer is even, and the polarity of surface of steel plate after using the process of this passivator, can be kept, the spraying of coating is carried out after being convenient to passivation, and the bonding strength of coating and steel plate greatly can be improved at a small amount of diatomite of steel plate passivation layer surface remnants, coating is combined more firm with steel plate.
When this Passivation Treatment temperature is 30-32 DEG C, Passivation Treatment better effects if, and also passivation speed is very fast.
Plating spraying can be carried out or brush in step (4) sprays paint step.
