Description
Technical field
This utility model is related to electrostatic powder coating technical field, especially relates to plate surface powder curing equipment.
Background technology
Electrostatic powder coating process comes across the sixties in 20th century, is mainly applied to coating metal surfaces.Enter 20 generation
Record the end of the nineties, with the development of powdery paints and spraying equipment, make electrostatic powder coating process be applied to nonmetallic surface
For possibility.
After powder paint technology enters application industry, powdery paints is occupied in general industry coating
The sustainable growth year by year of market ratio, its reason is the advantage that powder spray technology has uniqueness.
With the regulation that environmental law is increasingly stricter to organic volatile in an atmosphere (voc) content, application industry is tried always
Figure exploitation relatively mild application techniques to environment, after long-term research and experiment, finds that " electrostatic powder coating " is current
The application techniques the cleanest that can reach.Powdery paints does not use the volatile solvents such as organic solvent, water, is inorganic solvent
Type coating, this greatly reduces and result from the pollution nuisance of solvent, including because causing operator's containing organic solvent
Poisoning；Also will not because of organic solvent initiation fire.Emerge so far from powdery paints, also do not occurred because of powdery paints
And the serious accident causing.Powdery paints is the coating of pure solid constituent, can adopt full-automatic spraying completely, in a large number
Or surpass the powder spraying, easily collected by recovery system, reach the purpose of recycling.Therefore, the utilization rate of powdery paints is several
Up to 100% so that application industry reduces the processing cost of garbage, the degree of environmental pollution can be made to be preferably minimized simultaneously.
In the composition that film is formed, solvent-borne type is about 60%～65%, and powdery paints almost can reach 100% efficiency,
And it is not attached to be sprayed-on the powder of object, can be with recycling.Generally, using powder spray technology, painting can be made
Pretend industry and reach economy and effectiveness as far as possible.In powder coating operation, if there are spraying bad position, can without
Before baking, blown down using air gun, then carried out application again.Surface stream paint therefore can be avoided, drip the phenomenons such as paint, significantly
Reduce the probability that recoating is done over again.Because powder spray uses electrostatic spraying operation, coating equipment almost can reach full-automation,
Human resourcess are saved.Even if needing human assistance, application personnel also need not have been trained for a long time, you can grasps operant skill.
Powdery paints is 100% solid constituent, is not required to add any solvent, so coating content reduces, saves packaging, reduces storage empty
Between.
The extensive application that Electrostatic Spraying of powder Coatings is coated in industry of artificial boards not just merely because it is application techniques the cleanest,
Also as electrostatic powder mdf plate surface spraying solidification after formed envelope glaze layer color beautiful, and seal glaze layer can be by mdf
The poisonous hazardous substance sealing of sheet material itself, using safety.
For over ten years, electrostatic powder coating process and powder configuration reach its maturity, the coating quality of mdf sheet material more depends on
Improvement in equipment.And, the powder for spraying is divided into infrared attribute powder and ultraviolet attribute powder, at present, sprays factory pair
The powder answering both attributes builds a production equipment respectively, and cost is high.
