Description
Technical field
The present invention relates to lacquer spraying technique。
Background technology
There is processing step phenomenon inharmonious, irrational in existing lacquer spraying technique, produces sometimes to repeat to process or excess processes, have a strong impact on product quality, and percent defective is higher, require higher to employee's operant skill, cause product cost higher。
Additionally existing lacquer spraying technique processing step is tediously long, and the distribution of each operation exists many irrational places。
Summary of the invention
In order to realize the purpose of the present invention, the present invention provides the lacquer spraying technique that a kind of procedure arrangement is reasonable, coordinate。
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that
A kind of lacquer spraying technique, comprises the steps:
1) pre-treatment before, spraying paint
To checking qualified product block pattern row pattern in cleaning basket, it is ensured that exist between each of product and clean gap, surface is existed and carries out grinding process than the more serious place rubber paper got rusty。
01) ungrease treatment, qualified product is lifted up in ferrum defat or aluminum degreasing bath together with cleaning basket, product is totally immersed in groove, require that the concentration in ferrum degreasing bath is 10-20%, temperature is 35-45 degree Celsius, and degreasing time is 10-20 minute, and the concentration in aluminum degreasing bath is 6-10%, temperature is room temperature-45 degrees Celsius, and degreasing time is 2-5 minute。
02) washing processes, the product having be carried out ungrease treatment is put in rinsing bowl together with cleaning basket, product is totally immersed in clear water, suitably rock, action is not easily excessive, requiring that the overfall of rinsing bowl must be always on, water is cleaned in periodic replacement, it is ensured that the water quality in rinse bath meets washing requirement simultaneously。
03) table mediates reason, is put in table tune groove together with cleaning basket by the product having be carried out washing process, it is desirable to product is totally immersed in groove, requires that table adjusts the pH value in groove to be 7-9 simultaneously, and temperature is under room temperature, and the time is 10-20 minute。
04) bonderizing, the product mixed up by table is immersed in Phosphating Slot, product-free exposes in atmosphere, requiring that the total acid in Phosphating Slot is 22-28%, free acid concentration is 08-1.4%, and promoter concentration is 6-8%, product surface is made can fully to enter phosphatization, after phosphatization completes, whether detection phosphating coat is qualified, it is desirable to phosphating coat can guarantee that the salt spray test of 2 hours, and phosphatization thickness is at 3 6um。
05) cleaning treatment after phosphatization, immerses the product after bonderizing in rinse bath and washes, and requires rinse bath periodic replacement clear water, it is ensured that the water quality in rinse bath meets cleaning requirement, it is necessary to twice cleaning simultaneously。
06) blow water drying and processing, cleaned for phosphatization product is sling together with cleaning basket, be placed in appointment position, with high pressure air rifle, the cleaning water in product cavity blown。The product blowing water process being put into baking oven and carries out drying and processing, temperature controls within 180 degrees Celsius, makes the moisture in product fully dry。
07) drape over one's shoulders putty grinding process, after product phosphatization drying and processing, irregular surface is draped over one's shoulders putty and processes, it is ensured that product surface flatness, after draping over one's shoulders putty, it is carried out grinding process。
08) shielding processing, tests to the product after draping over one's shoulders putty polishing, confirms that whether product is qualified。The surface need not spray paint drawing requirement and stud, the screw thread of nut is protected with special adhesive tape。
2) spraying paint process, to checking qualified product block pattern row pattern in the support that sprays paint, prepare to spray paint process。
01) primer spray processes, and is hung in paint spraying frame by qualified product, notes the mutual collision prevented between product。Allotment priming paint, it is desirable to 91061 priming paint: BT110 all-purpose diluent: the ratio of Z92711 firming agent is 100:240:180, is filtered deployed priming paint processing the particle taken out in paint。Priming paint is connected with spray gun, process that product is sprayed paint, it is desirable to spray paint and want uniformly, it is ensured that base coat thickness is more than 40 μ。
02) drying and processing, to the product drying and processing having carried out prime treatment, it is desirable to the drying temperature of epoxy primer is 70 degrees Celsius, and the time is about 60 minutes, and alloy priming paint can carry out in natural environment, it is not necessary to oven for drying processes。
03) SK fluid sealant is broken, according to drawing requirement, inner chamber and all gaps of periphery in frame product are required for breaking fluid sealant, require that the fluid sealant on every gap is beaten in the same size, simultaneously before fluid sealant is but without dry solidification, with suds on finger-dipping, fluid sealant troweling is sliding or floating, it is ensured that glue is close to above gap, and gluing needs to dry after completing。
04) leaking test processes, the inner chamber of electrical appliance kit product needs to leak test, it is desirable to the intracavity at electrical appliance kit fills clear water, shelves more than two hours, anhydrous drain to other intracavity of side be considered as qualified, otherwise need again to play the process of SK fluid sealant。
05) color spray paint and varnish treated, checks that whether product is qualified, is hung in paint spraying frame by qualified product, notes the mutual collision prevented between product。Technological parameter allotment paint according to paint and varnish, is filtered deployed priming paint processing the particle taken out in paint。Paint is connected with spray gun, adjusts the temperature in spray room, humidity, process that product is sprayed paint。Requirement is sprayed paint and is wanted uniformly, it is ensured that base coat thickness is more than 40 μ, and surface is without bad phenomenon such as obvious drain spray and particles。
06) baking processes, and pushes in baking oven by the workpiece having sprayed finish paint together with paint spraying frame, adjusts baking oven according to the Flue curing parameter of paint。The stoving of the paint temperature of requirement Ral7024 is 60 degrees Celsius, and baking time is 60 minutes, and the stoving of the paint temperature of Ral9018 is 60 degrees Celsius, and baking time is 40 minutes。
