The sensory appeal of furniture with a silky,matte finish,characterized by low gloss and smooth roughness,is closely associated with the curing technology of the coating.This research investigates the influence of production parameters on the texture of matte finishes during the coating process,focusing on variables such as the volume of coating applied,the pre-curing energy of LED lamps,and the radiation energy of 254 nm excimer lamps.Using both single-factor experiments and response surface methodology,this study measures the roughness and gloss at an 85° angle after pre-curing with an LED lamp and curing with both 254 nm excimer lamps and a gallium-mercury arc lamp.Findings suggest that increases in coating volume and pre-curing energy reduce roughness and enhance gloss,with LED pre-curing energy exerting a more pronounced effect than coating volume.Additionally,as the radiation energy of the 254 nm excimer lamp increases,roughness initially increases before decreasing,while gloss decreases without further changes beyond 1400mJ/cm2.Applying the Box-Behnken design wwithin theresponse surface methodology,the results indicate that lower LED pre-curing energy,higher coating vvolumes,and 254 nm excimer lamp radiation energy increase roughness and decrease gloss.The order of impact on the coating's surface roughness and glossiness is as follows:LED pre-curing energy＞coating amount＞254 nm excimer lamp radiation energy.
