Embodiment 1
[0019] The component weight percentage content of the formaldehyde removal solution is 14% titanium dioxide, 0.52% sodium phosphate powder, 3.2% calcium carbonate powder, 0.03% xylene, 0.05% brown sugar, 2.2% metal manganese powder, and 80% thinner.
[0020] Brown sugar is exposed to the sun for 1h. Manganese metal powder is soaked in conventional sodium hydroxide solution for 2.5 days and then dried.
[0021] The process steps of the paint for furniture wood board in addition to formaldehyde: substrate processing → white blank treatment → spray primer → mixed top coat spray → post treatment;
[0022] Substrate processing: According to the door size and knife type of the order, use double-sided melamine facing MDF in CNC milling cutter type;
[0023] White billet treatment: Use 240# sandpaper to sand the white billet for the first time. After removing the fly dust, spray the sealing primer. After it is dry for 30 minutes, use 360# sandpaper for four-sided sanding. Fill the large reces...
