Description
Technical field
The utility model belongs to artificial board surface decoration technique field, and in particular to a kind of to use powdery paints artificial
Plate surface forms the production technology and production equipment of DE Specular Lighting decorative effect.
Background technology
Artificial board is detached through over mechanical processing using natural timber, non-wood plant, inorganic non-metallic material as raw material
After various unit materials, each unit material and other additive gluings are formed in the case where applying or not applying adhesive
Plank or pressing, include mainly multilayer solid wood board, particieboard and medium density fibre board (MDF) etc..In order to make the table of artificial board
Layer intensity higher, the service life is longer, appearance is more beautiful, generally can carry out spray paint or powder to the surface of artificial board
Spraying and decorating.
Traditional paint spray be use compressed ir spray gun by oil paint with misty even application in workpiece surface.Paint is in people
Life play an important role, be that modern society is indispensable, still, the whole world is volatilized from paint every year
The volatile organic matter (VOC) being out discharged into air is up to 10,000,000 tons, and China reaches 5,000,000 tons, is atmosphere pollution
Main source.Volatile organic matter (VOC) includes toxic heavy metal element；Benzene homologues, such as toluene, dimethylbenzene, benzene；Nuisance
Matter, such as free formaldehyde, carbimide, free styrene monomer；Ethylene glycol and glycol ether ester；Halogenated solvent class etc., in room
Can make us after inside reaching a certain concentration, in the short time feel headache, Nausea and vomiting, weak etc., will appear when serious twitch,
Stupor is even dead, and can hurt the liver, kidney, brain and nervous system of human body, causes failure of memory etc. serious
Consequence.When people are exposed under the working environment of VOC year in year out, even if special to will produce if human body under low VOC concentration
The toxicity of property, such as allergy and cancer.Therefore, countries in the world government has launched respectively the laws and regulations of control paint VOC.
European Union has REACH regulations and the RoHS instructions of stringent control VOC, the U.S. to have CARB regulations, China also to put into effect control VOC's
GB18581 forces standard, it is intended to which the domestic stem children furniture mark for controlling harmful substance is also implemented in August in 2012 on the 1st.With
Earth environment pollution situation is increasingly serious, and the environmental consciousness of people is continuously improved, and the emission control of VOC will become increasingly tighter
Lattice, the common recognition that green environment friendly coating will replace traditional solvent-based paints coating to become entire society.
The latest development trend of green environmental friendly coatings is water paint, powdery paints and solvent-free Gao Gu on our times
Part coating.Due to being free of organic solvent in solvent-free and water paint, VOC release problems are not will produce.Powder spray is typically
With static plastic spraying machine or other powder spraying apparatus powder paint to workpiece surface, under electrostatic interaction, powder can uniformly be inhaled
Workpiece surface is invested, powder bed is formed, powder bed forms final coating after excessively high temperature bakes baked, levelling, solidification.With traditional spray
Lacquer craftwork is compared, and organic solvent is not used in entire technical process yet, not will produce VOC release problems.While powder itself is not
It is non-toxic containing heavy metal, and powder unattached in powder spray operation can with recycling, no hazardous emission, because
And it is the technique of environmental protection.In addition the coating formed by powder spray is in mechanical strength, adhesive force, corrosion resistance, ageing-resistant
Property, the methods of cost be also better than traditional paint coating.
