Embodiment 1
[0025] Embodiment one water-based photocuring open varnish technological process
[0026] 1), blank processing
[0027] To patch holes and gaps, first use 180# white sandpaper to grind the plane, then use 240# white sandpaper to grind the lines and grooves by hand, and polish along the direction of the wood grain, so that the surface of the workpiece is smooth and smooth, the edges and corners of the four sides are smooth, and the lines and grooves are smooth , no stains, sand marks.
[0028] 2) Spray oil seal bottom (two-component water-based bottom)
[0029] Coating amount is generally 30 ~ 160g / m 2 Generally, it is sprayed evenly along the direction of the wood grain twice and dried at room temperature for 4 hours at 25°C.
[0030] 3), grinding
[0031] Use 240# white sandpaper to manually sand in place along the direction of the wood grain.
[0032] 4), wipe water Grace
[0033] Rotate and wipe the specified color Water Gliss on the surface of the workpiece evenly wi...
Embodiment 2
[0046] Embodiment two water-based photocuring open color paint technological process
[0047] 1), blank processing
[0048] To patch holes and gaps, first use 180# white sandpaper to grind the plane, then use 240# white sandpaper to grind the lines and grooves by hand, and polish along the direction of the wood grain, so that the surface of the workpiece is smooth and smooth, the edges and corners of the four sides are smooth, and the lines and grooves are smooth , no stains, sand marks.
[0049] 2) Spray solid color primer
[0050] Spray solid-color water-based light-curing primer, and the coating amount of the paint film is generally 40-120 g / m 2 . Spray one and a half crosses, spray evenly, and then dehydrate in a dehumidification room with a temperature of 23°C-35°C and a humidity of 16%-30% for 2 hours. There is no whitening on the surface, and it is cured by light.
[0051] 3), grinding
[0052] Use 320# emery cloth to polish it evenly without sand marks. Remember ...
Embodiment 3
[0065] Embodiment 3 Process flow of water-based light-curing sealing paint
[0066] 1), blank processing
[0067] To patch holes and gaps, first use 180# white sandpaper to grind the plane, then use 240# white sandpaper to grind the lines and grooves by hand, and polish along the direction of the wood grain, so that the surface of the workpiece is smooth and smooth, the edges and corners of the four sides are smooth, and the lines and grooves are smooth , no stains, sand marks.
[0068] 2), spray UV bottom
[0069] The amount of paint film coating is generally 30 ~ 120g / m 2 . Spray a cross, and after leveling for 5 minutes, it can be cured by light.
[0070] 3), grinding
[0071] Use 240#~320# emery cloth to polish it smoothly without sand marks. Remember not to sand through and affect the hiding power of the primer.
[0072] 4), spray bridging essential oil
[0073] Coating amount 20~50g / m 2 , spray evenly, and dry at room temperature for 2 hours at 25°C.
