摘要
在电场作用下, 通过聚醋酸乙烯乳液胶合杨木单板的正交试验, 探索了板坯垫板间电势差及单板含水率对胶合强度的影响。结果表明: 单板含水率和垫板间电势差及其交互作用对胶合强度都有极显著影响。在试验范围内达到理想胶合强度的垫板间电势差为30 V, 单板含水率为70 % ~90 % 。图1 表4
Based on the orthogonal tests of PVAc bonding to poplar veneers with the electric field,the influence of the electric potential differences of backing plates and moisture contents of veneer on adhesive strength was explored.The results showed that moisture content of veneer,the electric potential difference of backing plates and the interaction of them all had significantly effects on adhesive strength.Within test ranges,better adhesive strengthes could be obtained under 30 V of electric potential difference and 7 0%~9 0% of moisture content of veneer.
