Abstract

Studies address determination of the strength and water resistance of glue joints based on poly(vinyl acetate) dispersions according to EN 204 and EN 205 European Standard methods. These standards govern the test procedure and the required values when determining wood shear strength along its fibers. The strength and water resistance of the glue joints are determined using adhesives based on poly(vinyl acetate) dispersions of various brands. The quality of adhesive materials applied in the woodworking industry in Russia is analyzed, and recommendations for their further use are proposed. In the joinery-construction production, the D3 adhesives should be applied. The glue joints based on these adhesives may be used indoors under various temperature–humidity conditions. As a result of tests, the strength and water resistance of the glue joints formed by various brand adhesives are determined. It is shown that only four adhesive brands comply with the DIN EN 204–2003 D3 standard. Mobex 3335 adhesive, K-1 adhesive dispersion, and Kestokol D30 and Polidis PVA adhesives meet the DIN EN 204–2003 D3 standard in the average strength and water resistance. The Kestokol D300 adhesive shows the maximum strength and water resistance.

实木胶接强度和耐水性研究

研究涉及根据 EN 204 和 EN 205 欧洲标准方法测定基于聚（醋酸乙烯酯）分散体的胶接强度和耐水性。这些标准规定了测定木材纤维剪切强度时的测试程序和所需数值。使用不同品牌的聚醋酸乙烯酯分散体粘合剂可确定胶接强度和防水性。分析了俄罗斯木工行业使用的粘合剂材料的质量，并提出了进一步使用这些材料的建议。在细木工建筑生产中，应使用 D3 胶粘剂。基于这些粘合剂的胶合接头可在室内各种温湿度条件下使用。试验结果确定了不同品牌粘合剂形成的胶接强度和防水性。结果表明，只有四种品牌的粘合剂符合 DIN EN 204-2003 D3 标准。Mobex 3335 胶粘剂、K-1 胶粘剂分散体、Kestokol D30 和 Polidis PVA 胶粘剂的平均强度和耐水性符合 DIN EN 204-2003 D3 标准。Kestokol D300 胶粘剂具有最高强度和防水性。
