中文摘要 | 本報告係探討利用浸酚化粧單板與台板合板進行一次熱壓所製成之合板供為地板材料使用之可行性。化粧單板使用紅檜、栓木及紅樑等三種。面板區分為未浸酚與浸酚,共製成九類三十三種合板,進行其吸脫濕性及磨損性試驗,其結果歸納於次;(1)各種合板之氣乾比重均較其單板狀態稍增。(2)各種合板之吸濕平衡含水率與脫濕平衡含水率各為10%RH:2.5%~3.0%及2.6%~2.9%;45%RH:5.8%~6.2%及7.6%~8.2%;95%RH:13.2%~14.1%。(3)各種合板之平均吸濕膨潤率及平均脫濕收縮率各約為其實木狀態的1/10左右。(4)面板浸酚與塗裝的後其耐磨損性均改善甚多,重量減少改善效應;面板浸酚合板為75.7%~99.3%,表面塗裝PU合板為28.8%~71.0%。厚度減少改善效應:面板浸勵合板為84.8%~98.4%,表面塗裝PU合板為37.9%~76.7%。(5)面板浸酚合板之研磨重量減少與厚度減少量均會隨熱壓時壓力增加而呈直線狀減低。(6)各種合板之研磨重量減少量與厚度減少量均以與面板之木理方向成垂直者會大於平行者。(7)各種合板之吸濕膨潤率,脫濕收縮率及耐磨損性均不受其化鞋單板樹種的影響。(8)面板浸酚合板,其吸濕膨潤及脫濕收縮率均小,尺寸安定,且而磨損性大,足夠當作地板材料使用。 |
英文摘要 | This paper investigated the feasibility of using plywood hot-press overlaid with one layer of decorative veneer impregnated with PF resin for the flooring materials. Taiwan red cypress (Chamaecyparis formosensis) , Sen (Kalopanax sp.) and Red Oak (Quercus sp.) were used as the veneer materials and the face and back of veneers were either unimpregnated or impregnated with alcohol saluble phenolic resin. In total, three groups included thirty-three kind plywoods with different constuction were prepared for this study. The hygroscopic characteristics and abrasion resistance of those specimens were studied and the experimental results are summarized as follows: (1) The specific gravity of plywoods in air dry condition increased slightly as compared with those of veneers. (2) The equilibrium moisture content (EMC) of plywoods under adsorption and desorption at relative humidity conditions of 10%, 45% and 95% were 2.5%-3.0% and 2.6%-2.9%, 5.8%-6.2%, and 7.6%-8.2%, and 13.2%-14.1% and 13.1%-14.1% respectively. (3) The values of average swelling percentage and average shrinkage of plywoods were only the tenth of their solid wood. (4) The abrasion resistance of these plywoods could be significantly improved by the treatment of PF impregnation or coating with PU resin of their face veneers. The values for weight loss improvement were 75.7%-99.3% for plywoods faced with PF resin impregnated veneers, and 28.8%-71.0% for those coated with PU resin. While the values for thickness loss improvement were 84.8%-98.4% for the former, and 37.9%-76. 7% for the latter. (5) The amount of weight loss and thickness loss under sanding test for plywoods with face veneer impregnated with PF resin decreased linearly with the increase of the pressure during hot press for overlay process. (6) The values of weight and thickness loss in plywoods, overlaid with PF impregnated and unimpregnated veneers were greater for the case of sanding direction perpendicular to the fiber direction in the face veneer than those of parallel groups. (7) The absorptive swelling percent age, desorptive shrinkage percentage, and abrasion resistance were not influenced by the wood species of overlaid veneers. (8) The plywoods overlaid with veneer impregnated with PF resin are feasible to be used for the flooring materials because of their hygroscopic swelling and shrinkage are relatively low, and abrasion resistance is relatively high. |
