The invention relates to a kind of spray-coating device, espespecially a kind of spray-coating device of non-combustion meltallizing.
Background technology
Universalness along with 3C Product, electromagnetic interference (Electro-Magnetic Interfering, EMI) new public hazards have been become, no matter the consideration from electrical equipment normal operation demand or HUMAN HEALTH, electromagnetic interference problem has been subject to the common people's concern, and various countries are among the people or NGO also begins to pay attention to the Electromagnetic Interference problem, thereby stipulate the electromagnetic interference control test of various electronic products.Electromagnetic interference for the prevention electronic product, the most direct method is for using a shell with good electromagnetism screening effect that the circuit module of electronic product and the external world are intercepted fully, the better screening effect of metal shell tool now, yet, metal shell is to adopt sheet-metal forming now, therefore metal shell is quite heavy, and is difficult to be configured as through the mode of sheet-metal forming complicated exquisite profile.
Due to plastics tool plasticity-, can utilize mould to become required profile, so plastic casing remains the main flow of electronic product casing now, but plastic casing itself is non-conductive, and can't reach the purpose of covering electromagnetic radiation.Therefore the working method of plastics conductionization is developed, add electro-conductive fiber, plastic casing surface such as: plastics and spray electric conduction paint or electroless nickel plating or hot dip process or vacuum splashing and plating etc., but the working method of the plastics conductionization of prior art has the problem that tension force is not enough, sticking power is not enough or stress can't overcome, in addition, the galvanizing electrochemical plating have the problem of corrosion, and the pickle solution that the flushing electronplate is used can affect environment, therefore the product of galvanizing is by control or forbid peddling, and vacuum splashing and plating can't be used for large-area coating film based on cost consideration.
In addition, the surface working mode of prior art more includes the meltallizing cladding process, and the meltallizing mode that it adopts comprises flame plasma spraying, electric arc plasma spraying, oxygen fuel plasma spraying at a high speed alive and electricity slurry plasma spraying.See also Fig. 1, it is the structural representation of spray-coating device of the flame meltallizing of prior art.as shown in the figure, the spray-coating device 10 of the flame meltallizing of prior art is to comprise a nozzle 12, nozzle 12 inboards arrange a feed track 122, feed track 122 is carried and is sprayed material 14, be provided with plural fuel flow channel 124 and plural air flow channel 126 difference transfer the fuel and air around feed track 122, spray-coating device 10 is via nozzle 12 combustion fuels and air and produce flame 128, with spraying on material 14 to one base materials 16 of meltallizing feed track 122, spray layer 162 and form one, wherein spray material 14 and can be powder or wire rod, but the flame meltallizing can be with higher transfer of heat to base material 16, so can easily produce hydrogen embrittlement to iron and steel material quality, and affect the intensity of steel member, toughness and endurance.
as shown in Figure 2, it is for the spray-coating device of knowing the electric arc meltallizing 20 of prior art, it comprises a nozzle 22, plural number guide unit 24 and plural supply unit 26, those guide units 24 are arranged at nozzle 22 both sides, and the outlet of those guide units 24 is oppositely arranged, those supply units 26 are delivered to complex lead 262 respectively in those guide units 24, spray-coating device 30 is via the pressurized gas that produces electric arcs and utilize jet orifice 222 to spray in nozzle 22 outsides between those wires 262, with those wire 262 to one substrate surfaces 28 of meltallizing, spray layer 282 on substrate surface 28 and form one, but the electric arc meltallizing of prior art still has the problem that layer 282 is peeled off substrate surface 28 that sprays.
As shown in Figure 3, it is the spray-coating device 30 of the high speed oxygen fuel alive meltallizing of prior art, it comprises a nozzle 32, plural fuel flow channel 34, plural air flow channel 36 and and sprays material runner 38, fuel flow channel 34 carries the oxygen fuel of living to nozzle 32, air flow channel 36 carries pressurized air to nozzle 32, spray 38 conveyings of material runner and spray material 382 to nozzle 32, blow and the astable burning of the oxygen fuel of living by pressurized air, and cause producing seismic wave square 322, spray material 382 to one substrate surfaces 40 with meltallizing, form one and spray layer 42 on substrate surface 40.
as shown in Figure 4, it is the spray-coating device 50 of electricity slurry meltallizing, it comprises a nozzle 52, one positive electrode 54, one negative potential 56, plural number gas flow 58, plural powder syringe 522 is set around nozzle 52, positive electrode 54 is located on nozzle 52 inboards, it is inboard central that negative potential 56 is arranged at nozzle 52, the rare gas element of so carrying by gas flow 58 forms electricity slurry 524 by the electric arc between positive electrode 54 and negative potential 56, with the powder of meltallizing powder syringe 524 injection on a substrate surface 60, spray layer 62 on substrate surface 60 and form one, in addition, the melt temperature of electricity slurry meltallizing is quite high, need to carry out cooling by water-cooling pattern to nozzle 52, with rapid cooling, so electricity slurry meltallizing can increase cooling cost.As shown in following table one, it is the result that sprays of above-mentioned four kinds of meltallizing modes.
Table one
As shown in Table 1, the melt temperature of above-mentioned meltallizing mode is minimum is 80 degree Celsius, so still, can the hot melting plastic case surface, and affect the plastic casing outward appearance, in addition, because the melt temperature of above-mentioned meltallizing technology is higher, restricted for the upper meeting of selecting of base material, the base material that burning-point is lower or temperature tolerance is relatively poor, such as: paper, plastics etc. also can't utilize above-mentioned meltallizing technology to spray, so above-mentioned meltallizing mode can't be used for spraying all substrate surfaces, most of 3C electronic products also can't use above-mentioned meltallizing technology to carry out spraying of ELECTROMAGNETIC OBSCURANT simultaneously.
Therefore, a kind of spray-coating device of non-combustion meltallizing is proposed for the problems referred to above, not only improve the traditional metal shell and can't be configured as the shortcoming of random appearance and the shortcoming of conventional plastic shell conductionization processing, can promote the bond strength that sprays thing again, to address the above problem.
