砂光质量对改性速生杨木透明涂饰性能的影响

Influence of Sanding Quality on the Clear Painting Property of Modified Fast-growing Poplar

采用不同型号的砂纸对改性速生杨木进行的的砂光处理,然后用透明硝基漆和聚酯漆进行涂饰,研究砂纸目数对试件表面粗糙度的影响,分析表面粗糙度对漆膜的附着力的影响以及涂饰前后表面材色的变化。结果表明,240#的砂纸砂光最有利于漆膜附着力的提高和表面材色的天然质感的呈现。

The modified fast-growing poplar was painted with transparent coatings of nitrocellulose and polyester after sanding by different types of sand papers. The paper discussed how the surface roughness of test specimens affected by sand paper, the relationship of coating film adhesion and surface roughness. The results indicate that sanding with the 240# sand paper can enhance coating films adhesion and render the nature color of wood surface.
