ABSTRACT

Evaluation of the effects of 8% methanol (MeOH) pretreatment on the finishing performance of Acacia mangium wood was carried out using different coating systems, i.e., nitrocellulose (NC), acid catalysed (AC) and polyurethane (PU). The coated surfaces were tested for adhesion test-cross cut, scratch resistance test, abrasion test, impact resistance test, surface roughness, and gloss measurements test according to the relevant standard. The results have shown that A. mangium wood surface treated with 8% methanol resulted in a superior finished surface compared to untreated panels except gloss. Among coating systems, AC and PU appear to be more compatible with MeOH than with NC. Applying 8% of methanol to A. mangium surface before coating, application of AC or PU improved the quality of finished A. mangium wood and meeting the minimum requirements outlined in the standards.

甲醇表面处理相思锰木的涂饰性能

摘要

使用不同的涂料体系,即硝酸纤维素 (NC)、酸催化 (AC) 和聚氨酯 (PU),评估了 8% 甲醇 (MeOH) 预处理对相思锰木饰面性能的影响。根据相关标准对涂层表面进行附着力测试-划格测试、耐刮擦测试、磨损测试、抗冲击测试、表面粗糙度和光泽度测量测试。结果表明,与未经处理的面板相比,用 8% 甲醇处理过的A. mangium木材表面除了光泽外,产生了更出色的成品表面。在涂料体系中,AC 和 PU 似乎与 MeOH 比与 NC 更兼容。将 8% 的甲醇用于A. mangium在涂层之前的表面,AC 或 PU 的应用提高了成品A. mangium木材的质量,并满足标准中列出的最低要求。
