Description
Technical field
Transparent matt top coat top coat is repaired the present invention relates to LED-UV woodenware.
Background technology
At present at finishing work scene, due to the imprudence or other factorses of workmen, make already installed wood
Device gadget surface, which is scratched or encountered, small depression, and field patch recovery must just be carried out by such case occur, traditional
Method is all that repairing filling is carried out using PU paints or PE paints, and the paint film time to be dried of traditional PU paint PE paints is long
Dust and impurity in (needing 5-8 hours paint films to do solid work completely, to carry out next process), air, can not have in paint film
This period (30-60 minute) of complete surface drying is interior, flies to coating surface, causes after paint film does solid work completely, surface effect is poor,
Gloss is unstable, the bad situation such as feel difference.
UV paints currently used in the market have the characteristics of efficiently (paint film can be achieved in 3-5 seconds to be fully cured), typically all
It is to use high-pressure sodium lamp luminous radiation, carrys out cross-linking and curing reaction and complete paint film forming.High-pressure sodium lamp is high (generally due to power
80W/cm), with strong light intensity brightness, it can produce ozone when very strong heat radiation and work and need supporting radiating system
System, therefore be unpractical in engineering construction onsite application, and the appearance of LED-UV lamps compensate for this defect, LED-UV lamp works
As when there is low (general portable LED-UV curing the be 9-12W) heat radiation of power small (impinging upon workpiece surface just increase by 3 degree of left sides
Right temperature, and 20 degree or sos of workpiece surface temperature of conventional high-pressure mercury lantern festival increase), ozone free generation, availability height, volume
