Abstract
The invention discloses a powder spray process for fitness equipment. The powder spray process includes the following steps that firstly, early-stage preparation is conducted, whether a spray box and an oven work normally or not is checked, and powder of the required specification is put into a powder cylinder; secondly, a workpiece to be sprayed with the powder is put into the spray box and then subjected to electrostatic spraying more than three times, and the thickness of the powder on the surface of the workpiece is kept larger than or equal to 100 micrometers; thirdly, the workpiece sprayed with the powder is hung in the oven, and the temperature of the oven is adjusted to range from 180 DEG C to 220 DEG C and kept for 10 minutes to 15 minutes; and fourthly, the baked workpiece is air-dried and cured and then taken down. According to the powder spray process, electrostatic spraying is conducted on the workpiece of the fitness equipment more than three times, the workpiece is then put into the oven to be baked, it is guaranteed that the surface of the fitness equipment has high water resistance and corrosion resistance, meanwhile electrostatic spraying is adopted, the thickness of the powder on the surface of the workpiece is kept larger than or equal to 100 micrometers, and it is guaranteed that the painted face of the equipment is even and smooth after the workpiece is taken out of the oven.
Description
Technical field
The invention belongs to equipment manufacture field, specifically a kind of powder injection process of body-building equipment.
Background technology
Powder injection process also claims powder coating, and be a kind of Novel coating technique developed rapidly nearly decades, the raw material used is plastic powders.Just to begin one's study experiment as far back as some country of the forties, but make slow progress.Polyethylene fluidized bed process applies successfully by Zhan's nurse of Germany in 1954; after the Leroy Samse company invention powder electrostatic spraying of France in 1962; powder coating just starts formally to adopt in production; in recent years because various countries are to the attention of environmental protection; to the powdery paints that water and air do not pollute, obtain fast development.
General principle: form a high-voltage corona discharge electric field between spray gun and workpiece, when powder particle is sprayed through region of discharge by gun slot, just a large amount of electronics of supplementary set, becomes electronegative particulate, under the effect of electrostatic attraction, be adsorbed to positively charged workpiece and get on.When powder is attached to certain thickness, then can there is the effect of " two like magnetic poles repel each other ", can not absorption powder again, thus make the powder layer thickness of each several part even, then after baking-curing of heating, bisque levelling becomes uniform rete; Powder Electrostatic Coating Technology flow process, typical Powder Electrostatic Coating Technology flow process is as follows: upper part → degreasing → clean → derust → cleaning → phosphatization → cleaning → passivation → electrostatic powder spraying → solidification → cooling → lower part; Affect the principal element of electrostatic powder spraying quality.
In field of exercise equipment, powder injection process is applied too, but body-building equipment has certain particularity, especially outdoor body-building equipment, owing to being in outdoor environment for a long time, not only to the resistance to water, corrosion resistance etc. of equipment, all there is higher requirement, also require that equipment surface can keep smooth for a long time simultaneously, without point without hole.Traditional like this dusts in the just needs further improvement of body-building equipment manufacture field, to meet the special technological requirement of body-building equipment.
Summary of the invention

(2) workpiece to be dusted is sent into spray box, carry out more than three times electrostatic sprayings, the powder thickness of surface of the work remains on >=100um, guarantees surface of the work powder uniform ground, without point without hole;
(3) after dusting, workpiece is linked in baking box, and avoids contacting with each other between workpiece, and regulate the temperature of baking box to reach 180 DEG C ~ 220 DEG C, constant temperature time is 10 ~ 15 minutes;
(4) baked workpiece is carried out drying solidification, and hang under workpiece.
The present invention further preferably technical scheme is, when workpiece is multiple color, before step (3), first oven temperature is adjusted to 120 DEG C ~ 150 DEG C, and inserts in baking box by workpiece, constant temperature 15 minutes.
Preferably, anti-ultraviolet stabilizing agent is also mixed with in the powder of specification needed in step (1).
Preferably, in step (1), the powder of required specification is that outdoor environmental protection polyester sprays last coating.
Preferably, will before workpiece be dusted sends into spray box in step (2), first check the surface of workpiece to be dusted without plane ash, polish and the phenomenon such as failure welding.
Preferably, before workpiece feeding spray box to be dusted, first air blowing dedusting will be carried out to surface of the work in step (2).
Preferably, check before Refresh Product being dusted that workpiece does not exist original paint.
Beneficial effect: first the workpiece of body-building equipment is carried out more than 3 times electrostatic sprayings by (1) the present invention, insert baking box again and carry out roasting knot, guarantee that the surface of body-building equipment has higher water-fast and corrosion resistance, simultaneously owing to adopting electrostatic spraying, and the powder thickness of surface of the work remains on >=100um, ensure that workpiece is after taking-up baking box, the lacquer painting of equipment is even, smooth;
(2) the present invention is when processing the workpiece of multiple color, first oven temperature is adjusted to 120 DEG C ~ 150 DEG C, and inserts in baking box by workpiece, constant temperature 15 minutes, the powder of surface of the work is melted, then carries out roasting knot, can prevent dyeing, guarantee that surface of the work is bright in luster;
(3) the present invention adopts outdoor environmental protection polyester to spray last coating, and mix anti-ultraviolet stabilizing agent, the powder of workpiece surface spraying hot setting in baking box can be promoted, make equipment surface smooth, and there is uvioresistant,, there is not be full of cracks, every being coated with the defects such as show-through, bubble and heavier current mark, elephant skin in the advantage of difficult drop-off, simultaneously equipment surface uniform color.
