Description
Technical field
The present invention relates to a kind of coating process, in particular to a kind of auto parts and components novel coating line improves work
Skill.
Background technology
Painting dressing automobiles refer generally to the application of the various types such as car, car, cargo vehicle body of a motor car and parts.Vapour
The vehicles one of of the vehicle as modernization, 90% or more outer surface is painted surface, coating quality (appearance, clarity, light
Pool, color etc.) quality be visual evaluation of the people to car mass, therefore it is the competition for directly affecting automobile labor market
Power.In addition, coating quality is also one of the major measure for improving the corrosion resistance of automobile product and prolonging the service life, so,
Car surface application is all classified as important work by either automobile making or automobile maintenance industry.
The paintings such as automobile assembly line using coatings volatile organic compounds as generated a large amount of VOC, also heavy metal problem.European car
Application film coating technique substitutes application, and application uses aqueous and powdery paints as possible, is far below European Emission laws and regulations requirement.
Since the requirement along with the whole world to environmental protection coating material is higher and higher, more environmentally friendly aqueous and powdery paints at
For Coating Market hot product, wherein requirement of the whole world to environmentally friendly trend is to push a big power of powdery paints development, due to
The approach for reducing product VOC is all being found by manufacturer, therefore in certain field powdery paints naturally instead of liquid coating.Powder
The VOC content of last coating is low, removes and is easy, and crosses the recyclable recycling of coating of spray；Film does not generate pin hole substantially after construction,
Construction usually easier than liquid coating, the film durability of formation are good.Environment-friendly advantage and technical advantage are that powdery paints substitutes biography
The key point of system solvent based coating.
Water paint can greatly reduce the discharge of VOC relative to traditional solvent-borne coating, can effectively reduce to environment
It influences, additionally aids the pathogenetic potential probability of reduction occupation, reduce fire risk and storage hidden danger, simplify and reduce enterprise and is logical
Flow and cost of wind, water process etc. etc., everything demand are also all that certain basis has been established in the development of water paint.
Invention content
Deficiency in for the above-mentioned prior art, the present invention provide a kind of reduction production cost, improve the vapour of production efficiency
Vehicle parts novel coating line modified technique.
