The performance and characteristics of UV Coatings

 First, drying (curing) rate: with the traditional polyester or polyurethane compared, UV paint on the ambient temperature almost does not require the actual curing time for only a few seconds, you can enter the next process or direct packaging. And polyester or polyurethane paint for 4-8 hours, heating also need to bake for 2 hours;

 Second, energy consumption: with paint or other energy-saving coatings, infrared-based paint and coatings compared to microwave, UV ultra-violet curing coating the lowest energy consumption, less than one-tenth of other coatings. Heat-curing solvent-based paint, curing process of a lot of heat for heating the air, was painted objects, as well as solvent evaporation, and only 20% of the heat for curing resin. Varieties of heat-curing coating type (amino paint) water-based paint powder coating paint UV energy 1.1 0.76 0.46 0.046

 Third, production efficiency: UV paint curing rate due to high, the most appropriate organization of large-scale intensive production to UV curing device as the core of UV coating production lines, is the fastest growing sectors of modern painting, the production cycle as soon as possible forms of production, its efficiency as high as other coating production lines unmatched, and its advantage is mainly manifested in the following areas:

 1, short production cycle: 5.5 square meters in order to paint the wooden doors for example, polyester, polyurethane, and the amino acid and other traditional coating, a coating generally dry cycle for four hours in summer, winter is about 8 hours or more, the entire painting three times a day and night cycle, coupled with the frequency of intermittent coating and coating total conservation period 4-5 days, and UV coating that is only one days time to complete.

 2, saving the production of the venues and infrastructure investment: the wooden doors are still painting as an example: In accordance with painting classes every single production of 100 sets of wooden doors assembly-line basis, each workpiece placed stents, Chen Fang four sets of wooden doors, the need for 50 Chen Fang primer planes, 25 Topcoat Chen Fang stent, for a total of 75 Workpiece stents, each covers an area of six square meters stent workpiece (including the channel), the plant is about 450 square meters, two-thirds of winter, it needs to be increased , about 750 square meters. 0.5 yuan per square meter per day venue fee per year is about 135,000 yuan venues cost inputs, each workpiece mount cost 300 yuan, the increase in investment in fixed assets is about 22,500 yuan. Since the moment the UV curing paint, the workpiece can be stacking upon curing or finished product packaging, without having to wait for dry venues and related facilities, greatly reducing the production of venue rental costs and the investment in fixed assets.

 3, to reduce the input of human resources: As the UV characteristics of fast-curing paint, very suitable for the use of coating production lines. 600 mm wide with a floor production line for example, single-class production of 600 square meters can be painting, the number of 25; and traditional polyurethane coating or paint, it would take 130 people, the production cycle should be 4-5 days. UV coating efficiency than traditional painting at least 5 times.

 4, reducing the process: At present, from the wood flooring, to the steel sheet, optical fiber, printing and production of cans and many other areas of flat paint, have formed a mature technology, only three-dimensional curing has been a long time to overcome global challenges . However, UV curing of the workpiece plane only positive and negative sides respectively, and the four sides also need to be dealt with separately alone, it normally takes more than 26 process; In contrast, three-dimensional curing process of curing a single, 20 seconds, three-dimensional completed, UV paint spraying and whether more thick will not crack. Spray the entire curing process takes 10 procedures.
