Description
Technical field
The present invention relates to plastic material powder injection process, specially a kind of nylon adds the work of dusting of the plastic material of glass fibre
Skill.
Background technology
Dust and refer to make powdery type clagging in a kind of coating process on workpiece after dusting again pass through with corona discharge
It successfully, is process essential in Modern High-Speed multi-color blanket technique that heat, which coats, and traditional powder injection process, refers at home
Dusted above hardware material, and the powder injection process on plastic cement is also in developing stage, substantially a blank stage, is moulding
On the powder injection process of glue material, the emphasis of problem is to need solve conductive, adhesive force and roasting temperature etc..
The content of the invention
For problem above, the powder injection process of the plastic material of glass fibre is added the invention provides a kind of nylon, is passed through
Powder injection process, protective is provided for glue part, to extend the service life of glue part, next to that it is ornamental, reach aesthetically pleasing, again
It is specific use, to reach adiabatic, fire prevention, waterproof and other effects.
To achieve the above object, the present invention provides following technical scheme：A kind of nylon adds the plastic material of glass fibre
Powder injection process, comprise the following steps that：
A, the spray-coating surface of glue part is wiped or soaked first with white spirit or industrial alcohol, it is ensured that glue part spray-coating surface is without any
Greasy dirt matter, then air-dry or dry；
B, wiped, soaked or sprayed using conduction liquid onto glue part, make each part of glue part have conduction liquid covered with,
By drying or low temperature drying, it is ensured that glue part parches completely；
C, glue part is preheated using preheater, preheating temperature is 60-80 degree, ensures that the electric conductivity of glue part is in complete shape
State, then according to the actual conditions of glue part, regulation and control dust process when the electric current of podwer gun used, rifle is away from, thickness；
D, after spraying, glue part is put into roasting incubator roasting temperature, temperature control is located at perseverance in 140-200 degree, roasting warm time
Warm 25-40 minutes, it can be packed through supercooling.
Compared with prior art, the beneficial effects of the invention are as follows：First, powder injection process is coated in glue part reaches certain thickness
Degree, makes the corrosion resistant performance of glue part fine, there is provided protective, to extend the service life of glue part；Second, powder injection process possesses commonly
Spraying coating process without dicoration, bring aesthetically pleasing effect for glue part；3rd, powder injection process can be that glue part brings spy
Different purposes, to reach adiabatic, fire prevention, waterproof and other effects, improve the practical performance that glue part overcomes various environment；4th, work of dusting
The coating of skill is free of solvent, three wastes public hazards, improves labour health condition；5th, using the new of electrostatic powder spraying
Technique, efficiency high, suitable for automatic production line application, powder using efficiency is high, recyclable.
Embodiment
The technical scheme of the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment
Only part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the common skill in this area
The every other embodiment that art personnel are obtained under the premise of creative work is not made, belong to the model that the present invention protects
Enclose.
Embodiment：
The present invention provides a kind of technical scheme：A kind of nylon adds the powder injection process of the plastic material of glass fibre, including with
Lower processing step：
A, the spray-coating surface of glue part is wiped or soaked first with white spirit or industrial alcohol, it is ensured that glue part spray-coating surface is without any
Greasy dirt matter, then air-dry or dry；
B, wiped, soaked or sprayed using conduction liquid onto glue part, make each part of glue part have conduction liquid covered with,
By drying or low temperature drying, it is ensured that glue part parches completely；
C, glue part is preheated using preheater, preheating temperature is 60-80 degree, ensures that the electric conductivity of glue part is in complete shape
State, then according to the actual conditions of glue part, regulation and control dust process when the electric current of podwer gun used, rifle is away from, thickness；
D, after spraying, glue part is put into roasting incubator roasting temperature, temperature control is located at perseverance in 140-200 degree, roasting warm time
Warm 25-40 minutes, it can be packed through supercooling.
The general principle of the present invention：On glue part surface covered with conduction liquid, it is ensured that its electric conductivity, when powder injection process starts,
A high-voltage corona discharge electric field is formed between podwer gun and glue part, when powder particle is sprayed by gun slot passes through region of discharge,
Just the substantial amounts of electronics of supplementary set, turns into electronegative particulate, in the presence of electrostatic attraction, is adsorbed to positively charged workpiece
Up.When powder is attached to certain thickness, then the effect of " identical charges repel each other " can occur, it is impossible to absorption powder again, so that respectively
Partial powder layer thickness is uniform, and then bisque levelling turns into uniform film layer after heated baking-curing.
Wherein, application of powder injection process can obtain thicker coating, such as the coating of 80~150 μm of coating, with one
As common coatings volatile organic compoundses, about need coating 5~10 times, and then a can reaches the thickness with powdery paints.
And the resistivity of powder is ideal in 1010~1016 ohm/cms, the too low powder that is also easy to produce of resistivity is dividing
Dissipate, resistivity is too high to influence coating layer thickness.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
