A kind of center tooth plate of the present invention paint spraying technique, technological process is: the surface treatment-spray-applied primer of middle tooth plate-toast-level lacquer painting-spray paint-baking-inspection, adopt above-mentioned technological process can guarantee middle tooth plate surface cleaning when spraying, there are strict process conditions when spray-applied primer and finish paint, the paint spraying quality of middle tooth plate can be guaranteed.
Accompanying drawing explanation
According to drawings and embodiments the present invention is described in further detail below.
Fig. 1 is a kind of flow chart of center tooth plate paint spraying technique.
Detailed description of the invention
As shown in Figure 1, a kind of center tooth plate paint spraying technique described in the embodiment of the present invention, comprises the following steps:
1) surface treatment: oil removing, rust cleaning and dedusting;
When carrying out oil removing to center tooth plate, adopt the mixed treating liquid of 401 degreasers and water, 401 degreasers: the mass ratio of water is 1:10, the contaminated situation different according to middle tooth plate adopts different deoiling methods:
When a, locally (greasy dirt area is less than 30%), be directly stained with cleaning fluid with brush and scrub, cleaning up rear surface does not have greasy dirt; Cleaning fluid should be made during cleaning to flow, and the sediment produced between the operating period will be cleared up in time, otherwise cleaning effect does not reach requirement.
When b, large area (greasy dirt area is greater than 30%), steel part is put into cleaning fluid and soak and wash with brush, large steel piece surface has large area greasy dirt, when being difficult to find large-volume receptacle, needs cleaning fluid to rinse, and uses brush brush, by surface and oil contaminant except clean.
When eliminating rust to center tooth plate, to needing the steel piece surface of spray paint to carry out bead, after process, steel part returns rust area when being greater than 50% of the gross area, need re-start Shot Blasting.
2) spray-applied primer: the spray-applied primer in 4-12 hour of the middle tooth plate after effects on surface process;
That is: the steel part that surface treatment is qualified needs spray paint as early as possible, more than 12 hours, more than 4 hours, can not can not get rusty with the steel piece surface avoiding surface treatment qualified, or be stained with greasy dirt, dust and dirt time spring rainy weather (relative humidity 85%) under normal circumstances.The moist especially steel piece surface in south wind sky have obviously solidifying water time, can not direct spraying paint, first should toast, or bake with oxygen, spray paint again after the method dryings such as electrothermal blowing cylinder.
3) toast: toast the middle tooth plate after spray-applied primer, baking temperature is 90-100 DEG C, and baking time is 30-40 minute; When baking temperature is 90 DEG C, baking time is 40 minutes, and when baking temperature is 100 DEG C, baking time is 30 minutes, can according to concrete baking temperature determination baking time, and baking temperature is higher, and baking time is shorter.
4) lacquer painting is leveled: the lacquer painting of the middle tooth plate after baking is leveled; To ensure the quality of spray paint.
5) spray paint: spray paint in the middle tooth plate after lacquer painting is leveled 12 hours;
6) toast: toast the middle tooth plate after spray paint, baking temperature is 90-100 DEG C, and baking time is 30-40 minute, from dry 12-24 hour after baking; When baking temperature is 90 DEG C, baking time is 40 minutes, and when baking temperature is 100 DEG C, baking time is 30 minutes, can according to concrete baking temperature determination baking time, and baking temperature is higher, and baking time is shorter.
7) check: inspection outward appearance, coating layer thickness and adhesive force.
A, inspection presentation quality standard:
Qualified: spraying should be even, good without obvious elephant skin, bubble, attachment.
Excellent: spraying is even, color and luster is consistent, without elephant skin, sagging and bubble, attachment is good, and coating is without decortication and return rust.
B, inspection coating layer thickness standard:
The tolerance of application dry coating thickness and the method for inspection should conform with the regulations: dry coating required thickness value and permissible value should meet the requirements (mensuration of GB/T13452.2-1992 paint and varnish coating layer thickness);
Primer coating thickness=primer coating thickness measure mean value;
Total coating thickness measurement mean value-primer coating thickness measure mean value after topcoat thickness=coating finish;
Qualified:
1) the single-piece dry layer thickness mean value of sampling observation sum 70% reaches requirement;
2) the dry coating thickness mean value of all sampling observation steel parts reaches requirement;
3) underproof single products dry coating thickness mean value is not less than 70% of required thickness.
The standard of c, inspection adhesive force:
Adhesive force inspection (mensuration of GB/T13452.2-1992 paint and varnish coating layer thickness) is carried out to the coating on steel part;
Qualified: 2 or 1 grades
Excellent: 0 grade.
Preferably, in step 2) in center tooth plate spray-applied primer and when step 5) is to center tooth plate spray paint, adopt " wetting, it is wet to touch " technique, namely after spraying first pass, allow spraying position from dry a period of time, make partial solvent evaporate into surface drying, after surface to be coated is tack-free, spray second time again, by that analogy until reach coating thickness requirement.Need to strengthen spraying, to guarantee that the coating layer thickness of this position spraying paint reaches technological requirement at the position that the paint such as the position such as medial surface, end face, carding tooth surface of middle tooth plate and limit, angle, weld seam is not easy to arrive.
Present invention process flow process is: the surface treatment-spray-applied primer of middle tooth plate-toast-level lacquer painting-spray paint-baking-inspection, adopt above-mentioned technological process can guarantee middle tooth plate surface cleaning when spraying, there are strict process conditions when spray-applied primer and finish paint, the paint spraying quality of middle tooth plate can be guaranteed.
Last it is noted that the foregoing is only the preferred embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; it still can regulate the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
