Description
Technical field
The present invention relates to plastic-blasting technique field, specifically a kind of workmanship of spraying plastics flow.
Background technology
The electrostatic spraying of powdery paints is referred to as plastic-spraying, and its principle is：Powdery paints absorption is set to exist using corona discharge phenomenon
On workpiece.Its process is such：Powdery paints borrows compressed air gas to send into spray gun by powder-supply system, adds in spray gun front end
The high pressure for having HV generator to produce, due to corona discharge, produces intensive electric charge, powder is sprayed by rifle mouth in its vicinity
When, powered coating particle is formed, it is acted on by electrostatic force, is drawn onto with its opposite polarity workpiece up, with what is sprayed
Powder increases, and charge buildup is also more, when reaching certain thickness, due to producing electrostatic repulsion, does not just continue absorption, from
And whole workpiece is obtained certain thickness powder coating, then make powder melts, levelling, solidification through overheat, i.e., in workpiece table
Face forms hard film.
The content of the invention
It is an object of the invention to provide a kind of workmanship of spraying plastics flow, above-mentioned technological deficiency is solved.
To achieve the above object, the present invention provides following technical scheme：
A kind of workmanship of spraying plastics flow, comprises the following steps：
（1）Pretreatment：Surface sanding；
（2）Oil removing：Using 20-30% degreasing agent, it is heated to after 50-60 DEG C, immersion 20-30 minutes is carried out to workpiece；
（3）Once wash：Spot is washed away after being soaked 20-30 minutes to oil removing workpiece with 50 DEG C of clear water；
（4）Derusting：Workpiece is soaked 10-15 minutes with 30-40% Deruster for metal；
（5）Secondary washing：Dried after being rinsed well again to the workpiece after derusting with 60 DEG C of clear water；
（6）It is levelling：Applied according to the defect level of workpiece and scrape conductive putty, polished smooth after drying with sand paper smooth；
（7）Dedusting：Using electrostatic precipitation；
（8）Protection：If some positions have not required coating on workpiece, it can be covered up before preheating using Protection glue etc., to keep away
Exempt to spray coating；
（9）Preheating：Depend on the circumstances, some workpiece require that coating is thicker, and workpiece can be preheated to 150-200 DEG C, so can be with
Increase coating layer thickness；
（10）Spraying：In high-pressure electrostatic off field, podwer gun is connect into negative pole, workpiece grounding constitutes loop, and powder is by compressed air
Sprayed by spray gun and carry negative electrical charge, sprayed to by principle of opposite sex attraction on workpiece；
（11）Solidification：Heated in the drying room that workpiece after spraying is sent into 180~200 DEG C, make powder curing；
（12）Cleaning：After curing of coatings, protection is removed, smooth is repaired to the burr burr of coating；
（13）Examine：Check workpiece coating, it is all have drain spray, damage, the defect such as pin bubble, should all do over again and respray.
Compared with prior art, the beneficial effects of the invention are as follows：
The invention provides a kind of workmanship of spraying plastics flow, the workmanship of spraying plastics belongs to continuous productive process, and individual program is all linked with one another, it is impossible to
It is disconnected, it is energy-saving, and also method is simple, and plastic-spraying quality is good, difficult for drop-off.
Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
